We're off to start Okay, folks. This this weekend. We had a task force maxima had a weekend of action targeting criminal motorcycle gang participants throughout Queensland 23 search warrants were conducted and I've 53 offenders have been charged on a hundred hundred offenses you'll see there is a an amount of stolen property cash and Approximately or there was a hundred and thirty nine thousand dollars in cash seized at one premise I'll now hand over to Detective Inspector Smith from our tactical operations to oversaw the raids As indicated by the superintendent we conducted a series of operations throughout Queensland in conjunction with the regions We saw searches conducted in Mount Isa Townsville to Womba Morton and Brisbane the Gold Coast so we effectively targeted gangs all around the state as as indicated we've seized Weapons drugs cash. I mean it's hundred thirty nine thousand dollars as a significant find it should impact greatly upon their operations Not only did we do search warrants. We also looked at other Operations as well. We did traffic operations. We issued 60 odd traffic infringement notices We got a drink driver in colors. We got a CMG participant for drug driving So we're not just focusing on Criminal behavior in itself. We're looking at all their behavior all facets of their their criminal behavior from traffic right through to drug trafficking and things like that, so it's It really shows how as a service were pulled together to to target these people to effectively eliminate them from the community Are you confident that they'll like these patch members? Of the uh of the 55 persons arrested approximately 15 or 16 were CMG members the rest were Associates and I think it's important to note that there's consequences for people who want to Associate with CMG members It can't be socially acceptable to be a friend of a biking You have to learn that it's not on in Queensland I mean what what clubs are targeted? What clubs were a part of this? Look, uh, all criminal motorcycle gangs were targeted. However, uh, there were offenders from Banditos offenders from Hell's Angels offenders from the rebels motorcycle gangs And in their colors is simply a policy The uh in relation to them handing in their colors, uh, cannot say this that Whilst many of them have handed in their colors. We are still seeing serious crime being committed by gang members And uh, as the evidence comes to light We will arrest and prosecute those persons Does handing in your colors mean that you're exempt From prosecution under the CMG sort of bike blitz? No, it doesn't mean you're exempt if you if you are committing criminal offences You will be arrested and charged The legislation targets criminal organisations Bikes is just one limb of that So if you're a group of people committing criminal acts you will be targeted under this legislation Bikes is only one part Were there any drug syndicates that you think you've tapped into here and then some pseudo-athletes was taken? I think it's too early to say but we've got ongoing inquiries and relations and other addresses that we went to over the weekend Where have you found the snakes or what sort of snakes were they? To the pythons in our tattoo shop here in Brisbane They were being taken by their Department of Natural Resources to be a machine released back into the law. Hopefully not at my place Is the bike his pet of choice? It was uh I suppose you could say it was a chance discovery We were doing an audit of a tattoo parlor and we found the snakes, you know an aquarium in the front for your Any office holders, office bearers that were arrested during these blitz? We can say there were 15 participants Of criminal motorcycle gangs To continue up to keep up this effort running a couple of weeks out from Christmas How hard is it logistically to get all across Queensland and home in on these ones? Well, can I say this? I I think we will we will see even a greater push over the festive season through Christmas inter new year in relation to these investigations you know, it's our intent to Pursue the criminal motorcycle gang participants As long as we have to leave big Leave hasn't been cancelled however, I can say that there is a Uh A large amount of staff working over the Christmas festive periods Have all been reminded in custody Criminal motorcycle participants I refuse bail by police The other persons that were noticed to appear and so forth Can you give us a breakdown of those regions and how many in each? Do you have that? We'll be able to do that for you later years Has been going on for some time can you say whether There are people who have been charged from all the months You know, you might have charged them 10 weeks ago and now again It is a common occurrence to still be finding people doing the wrong thing I want to have to research those figures I can certainly say that there's people that we've charged in recent weeks that have been charged on numerous occasions And are on bail for other offenses And I think that is a clear indication of the criminality of these groups that they don't stop offending just because we arrest them Can you say some more about the the COF during whereabouts it was seized and was it a CMG or a participant involved in that? It was a CMG participant, it'd be inappropriate to say where we got it at this stage due to ongoing investigations And so another three arrested of that broad bench brawl, how many does that bring the total to? Yeah, I'm unsure of the exact numbers, but every day we're getting new pieces of evidence and that That leads to further offenders These recent arrests became available because we discovered New footage which identified more persons involved Bikings, biking footage? No, footage from police officers involved in that in that incident What's the reaction like when when you come knocking on the door of these people? Are they getting frustrated? Do you feel a sense of frustration from them? I hope so, I hope they are frustrated and until they learn to change their ways we'll keep coming back Like we want to make it the most uncomfortable place for them to do organized crime in Australia We do believe that we have been successful and there's a long way to go They'll go to court in the next few days, we've got to get the names from there Christmas time, are you expecting bikies to get together? The festive events? I don't know if it's expected, but it's certainly something we'll be investigating I mean, it's not just Maxima, it's the whole of the police service looking at the CMG We did about 50 walkthroughs of licensed premises on the weekend too Looking for offences under the legislation, the gathering or carrying prohibited items into licensed premises We're looking at all facets of legislation and we're looking at all opportunities to target these people And the possibility that there might be a few bikies having Christmas lunch with their family and the police might come knocking? Well if they're at home and it won't be an offence, but On each and every occasion We will take action if we have the evidence That's it folks. Thanks. Now there's some footage there. There's some jewelry inside


In our previous videos, we introduced one of the simplest classifiers, logistic regression. Today, the first step, like last time, is to paint some data like this. Now, for convenience, let me rename the variables x and y to x1 and x2, to clarify their independent variables and represent the inputs of our model. Now, I'll feed this data into the logistic regression widget and then send the developed model to the predictions widget to use on our training set. This process is prone to overfitting, but at the moment, I'm only interested in the decision boundary. So, let's visualize it in our scatterplot by coloring the points according to the predicted class. And let's also display each point's true class with its shape. Now, logistic regression develops a linear model. In two dimensions, it finds a line that best separates the instances of each class. Our decision boundary is somewhere around here, with all the blue points on one side and all the red points on the other. Now, a decision boundary found by logistic regression is represented as z equals w0 plus w1 times x1 plus w2 times x2. Here, z is proportional to the distance from the line, so points with a z of 0 lie directly on the decision boundary. Note that data points with a positive z are above the decision boundary. Logistic regression classifies them to c1, the blue class. Those with a negative z are below the decision boundary and are classified as c2. Now, logistic regression also outputs the class probabilities, when the distance to the decision boundary is large and positive, the likelihood of the first so-called target class c1 is high, and when z is large and negative, the probability of this class is small. So, let's visualize this probability with the size of points. You can see the probability approaches 1 as we move in this direction away and up from the decision boundary, and 0 as we move down in the other direction. To transform the weighted sum z into probabilities, logistic regression uses the logistic function called g. So, the probability of some class equals g of z, or 1 over 1 plus e to the negative z. Now, let's plot this function. When z is large, the output y, that is the probability of c1 approaches 1, and when the value of z is large but negative, the output y approaches 0. Now, we've explained this in our previous videos, so I apologize for the repetitiveness, but I need to remind everyone of the linear decision boundary and how the distance from it transforms into probabilities. Now, let me schematically represent the inner workings of our logistic regression. For our two-dimensional dataset, logistic regression receives a constant of 1, and features x1 and x2. It weights all of these inputs with w0, w1, and w2, and computes their sum, then transforms it with the logistic function g to obtain the probability y on the output. Great. Now, let's add some more data. I'll draw in some extra blue points like this. Obviously, it's impossible to split these two classes with just a single line. Just take a look at the scatter plot. Here, logistic regression fails miserably. This is the decision boundary. You can see many of the points are misclassified. So returning to our painted data, we need a more complex decision boundary. Maybe we could try composing it with two lines, like this. Now the points below these two lines should be red, and the rest should be blue. It looks like we might need two logistic regressions, one for each line, and then another that combines their two outputs. So let's draw this combination of logistic regressions. Here, two logistic regressions are fed the input features x1 and x2 directly, and the third combines their outputs. I'll emit the weight symbol to keep the graphics relevant, but note that each arrow contains one. Now weights are the parameters of our model, and this one contains six, plus another three, so nine parameters that must be inferred from our training data. Three logistic regressions together, or a network of logistic regressions. Now for historical reasons, such a network of logistic regressions is called a neural network. Neural because some researchers in the past were inspired by the way neurons process information. They also receive inputs from the synapses and dendrites, sum them up in the nucleus, and if the signal is sufficiently strong, fire along the axon. A little bit like logistic regression, perhaps. In any case, the artificial neural network we've graphically assembled here contains three logistic regressions and two layers. One layer, called the hidden layer, includes two neurons. It processes the input data and prepares it for the output layer, where we have one more neuron, and where we expect the class labeled data this layer receives to be linearly separable. Now we can construct such a neural network using the neural network widget in orange. We'll instruct it to contain only two neurons in the hidden layer, use the logistic function for activation, and an LBFGS solver to compute the weights from the training data. So let's pass this newly created model to the predictions widget and change the scatter plots color and size to show the results of our neural network. Wow, that works remarkably great. Most of the circles are blue and the crosses are red, just like they should be. Our small neural network with just three logistic regressions can easily cope with this data set. I can, however, easily construct a data set where my network will fail. Let me just paint another set of blue points here. The scatter plot shows that our network with two logistic regressions in the hidden layer cannot cope with our data set. Several circles belonging to C1 on the left are red, while they should be blue. Okay, we would need three logistic regression models to develop a classifier that combines model with linear decision boundaries, something like this. To do this, I only need to instruct orange to build a neural network with three hidden layers. So let me change this parameter in the neural network widget. And here's the result in scatter plot. Wow, we win again. A network with three logistic regressions in the hidden layer and one logistic regression as the output can produce a suitable model for our data set with a relatively non-trivial decision boundary. This, however, is just the peak of the iceberg as far as neural networks go. A few warnings are in order before we continue. First, we've been playing with a two-dimensional data set, and it was easy to devise just the right neural network architecture. Multidimensional data sets may require more complex decision boundaries, and figuring out the correct architecture is also very complex, even more so since there may not be only one hidden layer but multiple. And think about a data set of images, text, or any other unstructured data. While the neural networks for those applications are large, they stem from the same idea of combining simple models, like logistic regression, to fit possibly very complex data sets. We have yet to arrive there in this series, and there is still much to learn about classification, regression, feature ranking, selection, and overfitting. So stay with us.


You have to pay attention to detail and you have to give it your maximum effort. Division, attention! Welcome to the Only Easy Day was Yesterday, the official Navy SEAL podcast. Naval Special Warfare Preparatory School, otherwise known as NSW Prep, occurs in Great Lakes, Illinois, over two months. There is one goal of NSW Prep, to improve SEAL and SWIC candidates' mental and physical readiness to prepare them for the challenges of Buds and VCS. Cody Pearson, who you'll hear from today, is the program manager for NSW Prep and speaks about expectations for this major milestone in the process. Cody, thank you for taking the time to sit down with us. Obviously, you have a really unique perspective. We're hoping that we can transfer that to as many people as possible that want to find out more about what you do here. If you want to start a little bit about your career and kind of what let you hear, we can start there. Or if you just want to jump right into what you do right now, we can do that. Came in right out of high school. I was a state champion boxer before that. Not much pool work or swim work. Came straight into the Navy. September 11th happened when I was in first phase. Changed the course of how things I thought were going to happen. And I ended up doing two platoons at SEAL Team 1. I was a lead breacher and a lead vehicle driver for both those deployments. Ended up getting out. I was looking to start my own business. Got a call to come up here. This place had just started. Then they offered me a lead instructor position. Then over the course of four years, worked myself into the program manager position. And I've been the program manager for six years. In an overarching way, what is the Naval Special Warfare Preparatory School? And what is its kind of mission and goals? The mission of the NSW Preparatory School is to train, mentor, and coach perspective NSW SEAL and SWIC candidates in NSW-centric specific core physical and mental skills. Unpack that a little bit. What does that kind of mean in real world terms on a day-to-day basis for you? We try to prepare the students as best we can for the rigors that they're going to face out at Buds and at BCS. We basically want to help them get through the next major crucible, which would be Hell Week or the Tour. That's how we gauge our success. We do that by running, swimming, strength and conditioning. We have professional staff that does that.  We also talk to them about ethos, core values, some nutrition and injury prevention as well. Is everyone that's working at PREP here Navy staff? So we have a mix of Navy and civilian staff here. Civilian staff consists of coaches. So they're subject matter experts in running, swimming, strength and conditioning. They have education, kinesiology, exercise, science. We have two former SEALs that are working in tandem with those coaches to help deliver the NSW message and the way the students should be acting in those evolutions and explaining them why we do some of the things that we do. Okay. So how does this tie into the bootcamp piece that they're all going through at the same time? Is this after? Is this before? Is this during for laymen? Can you kind of paint that picture for us? Yes. For how this is structured, it would come from bootcamp, all enlisted people would come from bootcamp. And anybody that's from the fleet would come here. So we get all enlisted candidates for SEAL and SWIC. Okay. And that's right before they get shipped out to San Diego. Okay. So this election process is made and then they're transferred to you? Our goal from that is to take them from bootcamp or from the fleet and help prepare them in an eight week process. And get them out to buds as physically prepared, mentally prepared and injury free as possible. One thing that we try to help with is with their skills as far as running, swimming, strength and conditioning, exercise science, kinesiology. Try to help them as much as possible. What can recruits expect to experience whenever they're turned over to you or your team, so to speak? First off, they'll be expected to take a PST. They'll be expected to pass that PST. At that point, they should be able to pass a PST even on their worst day, so that there's no question. The PST basically assesses trainability. So if an individual falls short of the standards which are posted on SEAL SWIC.com in a PDF format, which candidates can go ahead, read, follow to the T, because that's exactly how we'll administer the test when they're here. There'll be an in-doc week process. And over the course of the next six weeks, it'll be a ramp-up training with the running and the swimming. And also the physical conditioning piece will be in the gym. It'll be on the beach doing sandbag PTs. There'll be out doing team building exercises, rope climbs, things of that nature. And then towards the end, we'll taper things off, get them ready, test them out on the exit tests. So there are two tests that happen here. One's the initial PST, and the other is the exit standard test. How is this exit PST different than the ones previous? Well, it's basically a lot larger. It's at the end of the pipeline here. Once they have successfully passed and they only get one shot at it, they'll be able to progress on to San Diego. Is that something that you think that recruits should try to be concerned with before they even get to basic training here? I don't feel like they need to really focus on that as much. Anybody that's listening to this probably needs to focus on their PST scores and make sure that those are inlined and to become as physically prepared as possible, but also bear in mind that they don't need to over-train. Are you getting the EOD and the other part of NSW coming through here, or is it just all SEAL SWIT candidates? It's all SEAL SWIT candidates. Okay. How long between graduating from boot camp and then getting to BUDS, are they in this phase where they're kind of ramping up if that's an appropriate word? So, we don't ramp them up immediately because we understand that in boot camp they will lose some shape. Most candidates will understand that as well. Once they get here, we'll take their PST scores and we'll basically try to put them in certain run groups if we need to. So, slower runners may be in a different group than some of the faster runners. What we do is we try to train the students as best as possible, given their weaknesses. So, they can talk to any of the coaches, they can pick their brains, that's what they're there for. Coaches are more of a positive motivation, vice the negative motivation that they would see out in San Diego a lot of times. So, it will help them basically find whether they're deficient, identify it, try to fix it. Midway through the training here, we do what we call mock exit test. So, it's the exact same 1000 meter swim, push-ups, sit-ups, pull-ups and a four mile run. The only difference is it's not a final test. It helps the individual identify if they are deficient in that, that they have the next four weeks to go ahead and try to work on where they are. To kind of get a baseline of where they're at. So, can you go back over the exit details in terms of the distance times and such one more time if we haven't already? The exit test is at the very end of the training pipeline here, and it will assess whether or not the individual be able to go out to San Diego or not, if they pass it on successful completion of it. The seal standards are a 1000 meter swim with fins, and that's combat size for a coneley. That has to be under 20 minutes. The push-ups have to be 70 in two minutes. The sit-ups would be 60 in two minutes. The pull-ups are 10. The run is four miles with pants, ten of shoes, and that's in 31 minutes or less. For the SWIC standard on the exit, it would be a 1000 meter swim as well with fins, combat size for a coneley. 22 minutes and 30 seconds is standard for that. Push-ups are for two minutes. They have to get 60. Sit-ups, 60 for two minutes. Pull-ups, 7. The run is three miles, and they have to do that in under 24 minutes. Do you and your staff see people failing to be able to hit these numbers this much into the pipeline? We've had multiple classes where everyone has passed the exit standard, and we've had everyone pass the PST as well, although there have been classes where some do not pass it, and unfortunately they don't identify as trainable at that point. Is those more ailment issues or is this kind of a point where people are flushed out initially in terms of fitness? As far as ailments are concerned, it should not be a concern because everybody needs to go into it healthy. We try to ensure that everybody's healthy, barring them, hiding some type of an injury, which we dissuade because they're not doing themselves a favor by going out to San Diego, or mostly themselves because it's kind of a detriment to them to be hurt and sent out there. When we do have medical staff here that are trained and willing to help with the rehabilitation process here. There's a strong focus on conditioning. What are some of your secondary or other main objectives with this aspect or this portion of the pipeline? Well, as far as other objectives, there will be some academic training, so we try to let them know as much as possible what their body is going to be going through while they're training with these individuals. There's injury prevention, nutrition, we give them classes in that, some mental toughness, and that's designed by our psychiatrist, psychologist in the center. We work on the core values and the ethos because their integrity is paramount. We do stress that quite a bit, so we try to send them out there prepared in that aspect as well. What else is expected of the candidates from you guys? As far as what's expected is 100% every day, they need to be here to perform. I would expect that any candidates that feel any pain or injured that they identify that here so that we can help them. They need to understand that this isn't to be gamed or something that you should be reading up on in the Internet to try to see how you get an angle. It's more about being very open and honest, mostly with yourself when it comes to training and putting forth the max effort when needed. And to also pick the coach's brains and to pick up where they're deficient. What type of assessments are you guys doing? Is this kind of something that's kind of ad hoc in terms of why you're watching these guys work out or how does that work? So as far as assessments are concerned, we track every score physically that they're doing so that we can kind of get a better idea physically of what the candidate's capable of doing. We'll do 3K time trials, we'll do tactical athlete tests. It's another battery of tests that we actually have to minister here. But we try to track their progress in almost everything from running, swimming, and strength and conditioning. And then put that together in a package. So it's constant. Correct. That's interesting. Yeah. Put it out there and do your best. But it doesn't seem like they do one thing wrong in their out in terms of performance. Absolutely not. We're not in a nutrition-centric phase of the training. We're here to try to mitigate that and build them up and send them out there. Guys are physically in shape as anybody that should be in their first platoon. But it really does boil down to the mental capacity once they get out to San Diego. And that's the hardest part. The hardest part of this for them is mental. Is that what you're saying? The hardest part, I think, with all of this training is mental. Physically, it's arduous. But it's something that everybody should be capable of doing. If I were able to take a seal's brain and put it in any one of these young man's body, you wouldn't say leave here. They'd be a Navy seal. You mentioned earlier about people trying to out-gain the system, especially with the amount of information that's available online and stuff in the media. I'd say you'd have to probably watch out for some of the books and the websites that are out there. I know that there's a lot of information and misinformation that can be passed. When it comes to this, there's a lot of attention towards it. I would say that if you're at Sealswick.com, that's the main source. That's the command's official word on how we conduct training and it has all that information in there. So I'm not saying that any of these, I don't know all these websites or all these books or if they're good or bad or indifferent. I can't attest to them. But I can tell any prospective candidate that if they're probably listening to this or they're on the right track, then you listen to their mentors and listen to their coordinators. Maybe just don't get too far into the weeds with things. You don't have to take cold showers for a year to prepare for cold ocean. Right, right. In light of that, is there any additional training or exposure to any apparatus or anything like that that you think is worthwhile for this part of the process? Because it seems like you're exposing them to some new things than what they've been accustomed to in trying to gain a certain PST score. Right. I think that a lot of candidates focus on their PST scores and their physical capabilities. But some of the things that they forget about are water comfortability, being comfortable in water. A lot of times at swim time or being a good swimmer doesn't translate or correlate with water comfortability. The two toughest things that we actually have to do or what students find the hardest here are sandbag PTs and treading the water with bricks which can be mitigated by possibly joining a water polo or recreationally diving as safely as possible. Safety constraints in place, not doing anything under water. Learning how to do an egg beater kick, learning how to tread water. Sandbag PTs, those are longer and they seem to be a little bit more arduous on the students when they're carrying them and it gets a little hot. Yeah, right. It's kind of a mental toughness piece with both of those. But getting the fins on their feet to help with their ankle flexibility prior to them coming in, even though the PST doesn't swim the fins, they're going to be having to swim the fins and buds and BCS predominantly. And a lot of the students end up with ankle pain. Right, right. Some of the pain that they will experience are, it's normal. It's just part of the process of building the strength and trying to build a better candidate. Some individuals don't understand that pain and it's okay if they need to see somebody in our medical department about it, which I do try to get them to do so we can rule it out if it is something they can work through. And if they can work through it, you have an athletic trainer on staff, try to get them back out into the evolutions and back into the training and help them understand it better. But prior to that, if they do any sandbag PT or any type of workouts with that or maybe even just snorkeling or things that are safe that they can do that helps kind of build that water comfortability. So the first time that they're in a situation, it's not completely brand new or something that they are wide-eyed about. Yeah, right. It's scared. Yeah, right. Because if they start off scared here, it's harder for us to train that in the short amount of time that we have them. What other parts of PrEP school do you think are valuable for people to know a little bit more about? I think that one of the things that they need to understand is priority coming to boot camp is some of the studies that we've seen this generation has 10% less bone density than prior generations. Wow. Which we see a lot of lower leg stress injuries, stress reactions, stress changes, and stress fractures, all which will set a candidate back or eliminate them from the program, which would be a disservice to a candidate if they're not preparing correctly in the beginning, if they're not doing things like obviously running and getting out there on a variable terrain in the right shoes at the right pace and not overtraining or doing too much. So it's kind of striking that fine balance between that. Also, vitamin D supplementation. We have a study that we're conducting now to see if some of the supplementation for vitamin D will actually help the students with some of the stress fractures or stress changes help mitigate some of that risk. You can get vitamin D from the sun, get vitamin D from milk. It does body good. It will strengthen your bones. I don't know if it's a cultural thing or what or people are just drinking less milk. I think it's a lot more video games with less running around. Yeah, get the controllers out of your hands and go outside and play. And that's one of the things like how somebody can prepare for prep is have fun with it. You don't have to go take the cold shower and stress out about what you're about to do. You should be very focused. You should be very professional in the way you want to train. That's why I say go ahead and snorkel or join a water polo team. Is there certain things that people should try to take advantage of while they're here that you see people maybe not doing or that you think people should kind of double down on while they're here? I think that what a candidate should take advantage of while they're here is the coaching. The coaches are here for them. They're open. They're able to talk to them. I think that they should do their homework prior to coming here. Obviously they're doing this if they're listening in this podcast right now. But to try to get as comfortable and to understand where they're going and to focus on this time as kind of a, it's a development time. It's a time for them to grow. We're not trying to attract them here. Yeah, I can see that. It's not part of the game. Yeah, people can come in thinking that they're going to be grilled and this is really an opportunity for them to learn. Right, and a lot of candidates come to us and they think that we're playing games with them or we're trying, you know, and we'll actually try to tell them something that we want them to listen to, but they're, oh, well, I think this is kind of a game or they read something somewhere. They've gotten a pass down from some other candidates or somebody that didn't make it through. So there's a lot of misinformation out there and to kind of stick to the ethos. I wish they could read as a civilian and start to memorize and kind of make that a part of their life, you know, prior to even coming in and help build that integrity and that good person, because that's where we're looking for good people that are also in shape and can do the job to mental capacity. So striking a fine balance before that, but you can do that by having fun, getting out there, going outside and playing, running, swimming, strength and conditioning, get the fins on. That way you're not shocked by the fins when you get here. Do a run analysis so you know what type of run shoe that you should be running in prior to that. They have professionals and they have different resources that are out there that are safe, especially this website, that they can reference and it will give them a good declination for them to follow. Yeah, yeah. Good direction. So short of not being able to hit their numbers, what other kind of reasons you see people dropping out of prep or being asked to leave? So we have a 12% attrition rate basically, so 12% of the candidates that we get here won't make it on to San Diego for one reason or the other. Less than half of that are because they drop or they quit. So we don't really see much quitting up here, which is a good thing. Yeah, yeah.  Correct. People before you are. Correct. I think that those individuals that do quit, some haven't even started, some didn't understand as well what they're getting into. Kind of that mental realization that this isn't for them, but it's few and far between. Yeah. We've heard that in talking that the why portion of the motivation for following through and wanting to become NSW candidate or active NSW is one of the most important parts because it's a foundation for whenever you're tired and when the chips are down, so to speak, that's got to be there. So you're going to want to go home. Exactly. Yeah. You need to be focused on what you're about to do. So if you have certain things or extra-curricular things that are pulling an individual's mind away from the task at hand, which is the number one thing that you should be focusing on is making it through training and everything that you do, even when you make that decision as a civilian prior to coming in, should help lend to that. So I think that based on talking to you and the research I've done, it's important for people to come into this part with an open mind and understand that they're getting help at this stage and to kind of continue to absorb from the people that are around. In terms of professionalism and knowledge, obviously continued hands-on training with technique and such, but this is not really a time to try to be a tough guy. This is a time for you to have personal development or physical development, the whole kind of the whole piece. True. But there will be some toughness pieces in this. Just the training alone on its own, it's tough. Right, right. Especially when you get to week six, you're doing interval runs, you're treading water. You're in much better shape, but it gets arduous. So there has to be some type of mental toughness when it comes to that. So there will be kind of a tough love feeling here because we're not here to coddle you. We're here to coach you.  And if you're injured, it's your job to let us know that you're injured so we can help you take care of that, get you healed, get you back on that pipeline. We're here for the same goal. We want to help you get through. The easier part is to have somebody quit, and that's butts. If somebody's going through that mental stress, but the reason we need that and the reason we do have to have a little bit of stress up here is because you can't throw grenades at you like it's time of war and see how you're going to react. You have to be stressed a little bit, help make those decisions. We'll talk about what was done or how they did it and they need to understand that there's consequences for making the wrong decisions as well and to try to kind of teach them before they go on to make any other mistakes and to kind of give them that NSW-centric mindset to help them succeed and to help our community with, like you're saying, a foundation that they can build on. And it is all building rocks. Folding your t-shirts may not translate to being overseas on a real-world mission. It doesn't translate in the beginning. You have to prove that you're capable of folding your t-shirts and capable of having shine boots, capable of doing these regular military things before we can trust you with a weapon that you're now going to have to clean, that it's going to have to be maintained, that possibly have to fire to save somebody, a teammate, a hostage, whatever. But that starts in the beginning. So it's all crawl-walk-run. We're in the crawl stage here. We've got to kind of set the candidate's declination as best as we can here to help them succeed, not only in first phase but future. And that goes with nutrition as well. They're stronger. They eat better. They're just a better candidate than we would have had prior to this coming through. And a lot of the guys that don't even make it and go onto the Navy take these key building blocks and help improve it, possibly come back around for a successful try, or they go out to the Navy and they do great things there and help build a better sailor. And that's really what we're here for. And anybody joining the military should understand that they're here to serve their country first and foremost. That's your building block. And what makes you want to serve your country and what makes you want to be that type of person, that great American? Is it driven by yourself, your own personal needs or is it driven by your capable, your willing, your motivated and you want to try to be that tip of the spear, that person one day. And you have the discipline to go ahead and train for it and train correctly for it and to have the focus in such a long pipeline to stick with it even when it's cold, wet, tired and those things will happen.  Yeah, right. So that's why we have to train like that. Well, thank you so much for sitting down with us. Your knowledge is really valuable to the people that are trying to come through this process. I think it's important to hear from as many people like you as possible. So we appreciate you taking the time. Thank you so much. Great. Thank you for having me.

We have very little time to fight climate change and avoid its worst impacts on migration. This is why the International Organization for Migration is proud to support the Midnight Survival Campaign of our long-standing partner, the Climate Vulnerable Forum. Climate migration is not an abstract concept, it is a daily reality. A reality experienced by countries most vulnerable to climate impacts, such as those belonging to the Climate Vulnerable Forum. Climate change already affects migration patterns around the world. Intense and disruptive events such as droughts, wildfires and heat waves are displacing millions of people each year. Looking ahead, even more is at stake. When a 1.5 degree Celsius global temperature rises, 30 to 60 million people are projected to live in hot areas, with temperatures to high for the human body to function well. With a 2 degree Celsius global temperature rise, this projection increases to more than 100 million people. It is time to act now. We need to make sure that climate action is efficient so people can live productive lives at home and are not forced to live. Thankfully, climate policy makers are increasingly aware that climate plans and policies can have positive impacts in terms of migration. Prior to the 2015 Paris Agreement, 20% of states intended national determined contributions referred to migration. States are now submitting their revised Paris Agreement to the nationally determined contributions before the Climate Survival deadline on 31 December 2020. Now more than ever, it is important to ensure that these new commitments reflect migration realities. IOM stands ready to support states in these efforts. Why? We proudly join the Climate Vulnerable Forum in its call for an ambitious collective response to combat climate change and that builds people at the center.


2020 Donald Trump is much different than 2016 Donald Trump because in 2016 Donald Trump was an actual Outsider so when he claimed that he was anti establishment He actually had a little bit of credibility But now that he's in power and now that he's in that DC bubble that he once criticized He's a different person. He doesn't know what to say To appeal to the voters he won over in 2016 and as a result He keeps shooting himself in the foot and it's astonishing to me that there aren't more people around him Well, he's tried to rain him in at least for purposes of self-preservation Because we just passed a gigantic milestone a really disturbing milestone when it comes to COVID-19 200,000 deaths in America Now I am a little bit worried honestly that as that number grows people will become more and more Insensitized desensitized I should say Because you know, there's a difference when when you see that one person died and there's a face to it You know, that really does have a different sort of impact on us at an individual level But when we just see like these giant numbers like 30,000 100,000 200,000 That is a little bit more difficult to grasp So I worry that people will become more desensitized as the number grows but regardless it's still a really disturbing milestone and Donald Trump did the dumbest thing imaginable to draw attention to the fact that we just passed this milestone By downplaying COVID-19 at a rally by saying the dumbest thing ever as we reached this milestone. Take a look The disease we didn't know it Now we know it affects elderly people elderly people with heart problems and other problems If they have other problems, that's what it really affects.  By the way, open your schools everybody open your school It affects virtually nobody by the way open your schools He says this as we pass 200,000 deaths if you said this when we were at like 185 There would be less attention drawn to it's still a lot of scrutiny But nonetheless not as bad as you say this as we cross this milestone He just keeps shooting himself in the foot and you can argue that he said a lot of idiotic things back in 2016 That should have theoretically ended his campaign when he said that Obama and Hillary Clinton founded ISIS I thought that was stupid when we got the grab them by the pussy tape I thought that was pretty devastating You know after you have woman after woman after woman accuse him of sexual assault or misconduct You know you think that at some point it have an effect, but you know Still after all of those things that he said in 2016 that were bad He still said enough things that made it seem as if he could still be an agent of change Even if he would bring chaos with said change that you know people decided to overlook all those weird things about Donald Trump But now four years later when we have this economic depression brought on by a global pandemic that none of us have ever had to deal with I mean things are different now now when you shoot yourself in the foot I think it actually will hurt you more does that mean that he's gonna lose not necessarily I still think that you know currently as it stands now according to public opinion polls Biden is the favorite to win But you know Trump's not out of it, but he keeps doing things to isolate voters to piss people off He just can't help himself. He just can't help himself and what worked back in 2016 like just Being a loudmouth idiot that might not work in 2020 now as I'm watching this Like I can't help but think who wants to watch this and listen to this old man Just babble on for hours at a time like he's not saying anything. He's not talking about anything meaningful He's not addressing anything like why would you go to a political rally if there's almost never any policy discussed Like he just talks about who's mean to him like it's not even entertaining like I'm tired of the shtick. I'm tired of the oh Trump said this. It's kind of funny I'm just over it.   You don't get policy. You don't get substance. So what's the point? Like I don't understand how people can tolerate this and put up with Donald Trump But regardless he keeps having these rallies where he says idiotic things and I you know I think maybe it's wishful thinking, but I think it's gonna hurt him more than it did in 2016 But you know, we'll wait and see because who knows, you know, there's a chance he says whatever and Gets away with it because the news cycle moves on pretty quickly. I mean just the week before last he Had this huge scandal that should have ended his presidency not just the campaign But his presidency where the Bob Woodward tapes confirmed he knew about the severity of COVID-19 But downplayed it anyway, like nobody's even talking about that So maybe it's the case that even if he's shooting himself in the foot It doesn't matter because you know, he get absorbed these blows it doesn't matter But I don't know I think that at a time when people want a leader to get us out of this mess out of this pandemic You can't be saying shit like this 200,000 Americans are dead and you're saying it affects virtually nobody.  It should be different like America has embraced Stupidity in anti-intellectualism with Donald Trump's presidency So, you know, maybe it's the case that we've been programmed and conditioned to just accept Stupidity from Donald Trump and when he says something stupid, you know The average American just scoffs or laughs at it because it's Trump. He's gonna be Trump But you know when I see this and he says that COVID-19 affects virtually nobody by the way open your schools as we lost 200,000 Americans. I can't help but think this has got to hurt him He's shooting himself in the foot. I mean again having a big mouth is Really great if you are trying to appeal to people and convince them that you're an outsider You're not a traditional politician, but nowadays I just I can't see how this is going to help him Where it's necessary like his die-hards the cultists, they're gonna love this But like the people who flipped from Obama to him in 2016. I can't imagine this is gonna resonate with them I think this is gonna turn them off if anything but again Who knows?  And whatever you do folks do not hit the notification bell either Mike treats me so unfairly


As we do start the enemies red and then do their raptors maybe crux All right. Well, she's starting red.   What the heck? They must be a four-man Dang and no leash. What a rough life we have here Is that the invade?  Oh, it's misfortune support.  No, I didn't hit it. I'm so bad. Oh man, I Am out of there. Peace late, dude Goodbye Thank you, Orianna. Oh, can she get that? Hello. Is that her? Is that her? Nice. Well, James on a rampage. GG boys. I'm coming baby We got this. Good job boys I'm coming. Whoa. What is that auto? What is that power thing? Get out of here. We did it Honestly, I hate saying this but I might start playing Lee Sin guys. I guess a backup He's he's really fun to play. He's just so cheesy Dang, I should really back right now Holy is that him? Is that him? I'm a Lee Sin main.  I would be afk. I Don't know. I really should back. I have like 3k gold, but he wants to do this then Team, why do you keep fighting?  Do we get an entire mall? Well, I'm feeling at least a two-man at least a two-man kick right here at least a two-man kick. Oh We didn't get the two-man, but that's okay because we got a zero kills I'm just soaking up damage at this point Okay, I'm feeling it. I'm feeling it Whoa Okay, this up two One and go get it. I think why I do so well in Lee Sin is because I'm just like I'm really strong at like Being aggressive and getting kills early game Because I play Kazakh so much and that's what Lee Sin's kind of about as well. Holy, okay. Let's back up No, I got knocked up No Dude, I took such a long journey.  That was actually so sick.  Sorry. I'm sorry Get him cause Nice flash. I got him team.  Lee Sin's broken And she's pushing bot.  Oh, man Hello Nope, we did it boys. Oh my god. I'm gonna live.  I had so much gold on me. I gotta start back anymore.  Oh, I hit that I have to go and I'm sorry stream Okay, big mistake big mistake big mistake. We can just end it here


My name is Robert Hanley. I'm the Quality Manager of Atlantic Language based in Galway. Robert, I want to start by asking you what challenges has the pandemic posed in your school? It posed plenty of challenges and I can go into that in a bit of detail now. Maybe just by prefacing remarks, I went about just gathering some input from our team on this procedure. I put out the questions to the group and just going to compile things in. I'll show you a couple of slides with testimony and feedback from our staff and I'll add some comments and context to that then I can as well. So in terms of the challenges, I'm not sharing my screen yet. That's the first challenge, bigger than Zoom. Yeah, I think everybody had to do that course. That should be visible now? Yeah. Yeah, so in terms of the challenges, there are some examples there when I put that question to the team, things they've commented on and you can see it kind of breaks down. The single biggest one I think is the uncertainty. The uncertainty, like the changing status of the school, with short notice, you're closed. Again, with fairly short notice, you're reopened and with a fairly short notice, you're closed again and you can't predict how the pandemic is going to go. But that's obviously the biggest challenge and that has an awful lot of repercussion, knock-on effects then as well. The uncertainty created by that. A couple of other challenges, like you know exactly where we fit in, the English language sector. We don't always know where we belong in terms of guidelines and the structure of the government. Sometimes we're in with further education and the colleges and maybe the instructions that come out in terms of how we operate aren't necessarily tailored to language tools and how we try to keep businesses going and keep businesses alive. And trying to find what's best for us, what's best for our students is a challenge in there as well. And the best practices, if you're going online, how you can do that is a challenge as well. And another big challenge then, like in some of the comments in green, kind of support that is just the disruption to the business, which is a huge catastrophic really. The entire language travel stream just cut off in one go, academic year, junior courses, training courses. And that of course leads to the unavoidable loss of staff, of loads of good staff, good teachers, people you're just not able to keep working. It's a huge challenge to try to keep the business operating, keep people working as much as possible. And even looking to the future, having people still there, whether we're able to keep working throughout this period, or had to be like go and come back, that challenge that you come back with just a stronger team is still a looming one. And because ultimately we've lost a high season, probably introducing a second high season with the spring next year as well. And then that has a spiriting effect on morale as well. It's hard to, with all just working remotely in the process, you lose that ability to check up on students, on staff, see how everyone's doing. And then the other challenge I think in some of the comments of lack there point to that just the logistics. If you move to online, if you do it very quickly without much running time, there's a lot of logistical challenges to that for students and for staff, trying to turn that into something sustainable that brings in revenue to keep the business going, looking for specific programs looking to deliver a form of online tuition for the general students, but also for specific partners to keep revenue going. That is a huge challenge in itself. You're trying to sell something while you're building it, while you're training, while you're also leading talented and qualified people. So that in itself is a challenge. And then not to mention the reopening and the logistical challenges and the housekeeping challenges of that as well, and finding a good way to keep the product going and try and get back to the old Atlantic was the challenge for the period when we were reopening. You know, teaching through the advisors and that presents a unique challenge in itself as well. And how would you say you and your team have responded to those challenges. I did mention some of the specifics of classroom challenges as well. Like, you can see some more feedback here from, from staff on how students have found it, you know, getting into the student were outside as well. So the ways we respond to these, you know, you have to be very reactive. It's the position we're in.  The same thing with staff preparing hardware for and then acquiring a whole new methodology we have doing business. So the ways we try and respond to it. One is the big one and you have to try and almost compensate for all that in face to face communication that that's lost, you know, and you try and get meetings online, you try and have support sessions, information sessions, Q&A sessions for students online as well. You try and have a check-in system, you use the accommodation, the business to check-in and students who are still in the accommodation. You try and have one to one where possible as well. So just compensating as much as possible communication. You know, keeping that communication going there with teachers is something as well, something we've tried to do. And hopefully we can do more with the likes of ELT Ireland as well and support groups to keep that communication going too because of that uncertainty about people's job prospects. Then like obviously the points in green there, there's a big adaptation on the teaching side. It's learned a whole new scale, it's tried to transfer teaching ability online. That's not done with the click of your fingers, that that's quite challenging and it's learning on the job. The people are often ready experiences as well in the process, but it's incumbent on teachers there and I can say ours has done really well with it, it just learned that whole new skills quite quickly and under pressure. And that comes from the other point I'd make there is just being as agile as possible. With fairly agile management, I think in terms of we were online within a week, I think of the first closure and then setting up a virtual learning environment shortly after that. So that agility, something we've obviously got better at throughout the year and it was really necessary now in hindsight to be able to operate quickly like that to set up things quickly to train up people to learn while working as well in order to set up new streams and start doing some of our tuition, some of our programs online. One of the points there is about keeping morale high. Can you tell us something more about that and how that was experienced for staff. It's a challenge because I mentioned in the process you almost forget that everyone's learning to work remotely as well. And that tends to, of us team are working from home as well so you lose that just the physical staff room, all that that brings with it, the chance to share a space, you have a more honest conversation face to face than you will in a kind of minute or two Zoom meeting. So that's the challenge to keep up the morale and you have to try and get creative and find ways to keep people in touch, you know, with their texting or meeting up like you're having groups or, you know, extending meetings beyond the necessary into maybe a chance for a bit more of a chat. Not to forget people are isolated at home and working from bedroom, kitchen, spare rooms as well. So they're trying to keep tabs, I think is vital. And then all you can do, particularly for the teachers who have to learn so much so quickly is just give them the resource, give them the training that they need to allow them to be able to do their job in this new reality as well as they can. All you can do is put it in front of them and you know competence then breeze breeze morale I think and then it just becomes it goes back to that first point I mentioned just just keeping tabs on people checking in people are okay. And how has the, how has feedback from either the staff or the students can informed your response. As you went along. I'll move on here. A couple of examples of our online classes there. There's a couple of visuals there. Maybe to go through some of the feedback for as we've received it first like this is some sample of student feedback because you know my own role that the team role at large will be to look at that feedback and try and extract by practice from it as much as we can. So you can see some student feedback here. You know, the teachers say like students, they do feel the pressure that you can see it ourselves in the communication students maybe will have a little bit less patients perhaps to wait for something might be a little bit more demanding but that comes with more written communication.  So we do, we have asked for more patients from students but also tried to double up and just communicate with them as well as possible and try and not always rely on just emails and give them a bit of context. We do see that students, interestingly, we're happier in the virtual setup than they were in the socially distanced classroom for feedback show that they're quite critical actually and exacting but as you expected them to be once we reopened on how that and they missed the the old relaxed way of the classroom. It wasn't the same what happened with students in the socially distanced. We found that once students settled in and we were able to train them to quit them to do classes online they actually preferred the online. And we also found that like, we, by keeping in touch we were able to maybe get students to continue their bookings to keep their, to keep their studies going as much as possible and transferring them online so that was one of the things we tried to do too. You can see some of the student direct feedback I've copied in there and read a couple of interesting points in it you know and just about exacting communication I've talked about what students are asking us to do and it's important for us to keep tabs on that. Interesting like they're hiring better teachers the same teachers. There must be there must be some positive feedback in there somewhere for hiring new people and we did interesting student feedback that we should reopen the bar. I didn't know we had a bar. It's there. It's well hidden in the student feedback. It is interesting. You know there's a staff feedback then as well. A couple of things I would take from that like when we asked for staff or feedback on the process. You know the communication point is everything, even though it's uncertain I think on certain communication is probably better than communication at all that's one thing we've learned. We've tried to find other creative ways to support and replace all that the common scenario was being in the same building. You have to do much more training and development for staff than you normally would particularly when it comes to teaching but other departments do like registrations and so forth. There's a whole there's a whole new field of training is needed. We try and bring that on and developing house training and power people to lead the way and take on training as well and then entering and joining you know teacher training group teacher interest groups and try to do team building activities as much as we can as well. Some of the ways we'll try to react. And apart from how to use zoom and all of that. What else would you say you've learned along the way as an organization or as professionals. I've got that question to the team as well. These are the some of the responses they got back. You can see kind of go from macro to micro there. Like the logistics, you can simplify what I'd say like learning to teach online, but that's transference as well as learning new digital competences using virtual classroom using the virtual learning environment, preparing for specific programs that they call for a slightly new technology. If we're able to bring in a new stream of business by teaching online. The onus is on everyone to scale up really really quickly on that so everyone has to a new skills in that. And it's, it can range from quite simple mechanical stuff to getting into things like inclusion and making sure students are communicating students aren't always the keyness to leave on a camera or to participate in the class or to have a proper kind of study atmosphere where they are so getting past that as well even into the making connections and relationships with students that that's a big challenge in terms of training and offscaling for teachers. Like another thing we've learned I would say when not very nice and I do when the colonists your hedge and move much quicker. We were able to move procedures online quicker than we would have done so in a different in a different universe without the pandemic. Things like testing level change testing, you know, students of the student services. You have to do it quickly and you have to kind of check later on for quality control and that you're doing it properly and everyone's doing the same way but the technology is there and the software is there and the willingness to learn we'd be glad to see is there as well. So some of these procedures online quite quickly. And when it goes back to a fully reopened school as possible I hope that's that's the skill set that's there. We're all more comfortable with them. More distance communication more online procedures more blended procedures around the communication of students but then in the classroom as well. And yeah, then the other main point like that we've taken from the business model needs to evolve a little bit, you know, we depending like the language travel industry is, you know, every few years there's another reason for there's another injection of volatility. And this time with the pandemic, but it numerous things can happen to that so it's critical I think in our context and maybe for the industry at large as well that we're able to react and not depending on on visa based programs and short stay groups that may be subject to disruption. You know, the pandemic this year came out of the blue but the world we live in now with travel so accessible and people make it so much that kind of thing can happen again or something else that we don't know about. So it's getting past that dependency on on on the stream courses of learning English and Ireland and try to move into more specific, maybe more sustainable models now that we've acquired a little bit of online competency and keep developing that competency, but also look for more alternate revenue streams outside of that as well because it's critical and simply learned that we have to be done. Absolutely. And then just to kind of round it up. Looking forward. How do you see the future in terms of what stays with us. What do we get back or what changes completely again. Once we're, once we're back to the status quo or something like it. Well, in the medium to long term. Yeah, it's very hard to predict. You know the, you can read a lot about the changing the changing workplace and and you know everything to really quickly react to working working from home working remotely team communication, becoming much more use getting familiar with cloud based stuff. You know file storage and things like that. That's all part of the new reality we're all able to do that now comfortable that now so that that changes things a bit. You know the disruption the commercial disruption to students traveling. There's no reason not to offer a digital component of that now. Why shouldn't students be able to do a few weeks sort of before before traveling to the country. Why shouldn't things like placement testing we don't online so that that you know as maybe it's just ingenious to say but it's the most modern in terms of technologically speaking of an industry either. Because accepted maybe, but we can use we can use the tools that are there a bit more so that the rate of progress there I think has been vastly accelerated. This uncertainty like the first point I made that that's not going anywhere. What we've taken from it is a more transparent way to communicate with all the stakeholders with students you know with staff. The agents remember those were just this honestly that transparency, even if you are communicating uncertainty it's still it's still communication and. Yeah, I think the pressure that one of the responses to the challenges has been top the game in terms of communication is still much more to be done but hopefully that's that's something everyone can take from it as well. You know, it was schools teachers staff students that everyone that that circle of communication is much further and more transparent for everybody involved with something I would hope to emerge in this as well as a positive aside from being very, very deeper and quick with the zoom buttons.


In this segment, what we're going to do, we're going to examine the question, why study fluid mechanics? Now, it turns out that fluid mechanics plays a very important role in our lives. It runs throughout our bodies, we breathe in air, that's a fluid, it governs the atmosphere of the earth. Life on earth is very much fluid dependent, but what we're going to do, we're going to take a look at a number of different applications where fluid mechanics is very important. We'll start off by transportation and we'll look at commercial aviation for the most part there. We'll then look at buoyancy driven flows. We'll then move on to atmospheric oceanic flows. We'll then take a look at flow instabilities and we'll conclude with some of the fun aspects of fluid mechanics and I'll call that entertaining flows. So, to begin with what we're going to do, let's take a look at transportation and as I mentioned we're going to be looking at aviation related civilian aviation transportation. So let's look at some video clips on that. So what you're looking at here is the engine of a 777, this is on taxi in Montreal and what you'll notice on the inlet to the engine, there's a light dusting of snow on the ground and you can see a vortex forming. That vortex is originating due to the swirl on the inlet to the engine due to the compressor blades that are spinning around and through the Helmholtz vortex theorems we know that vortex lines can either end on themselves like a smoke ring, they can go to infinity or they can end on a planar surface, a wall and so what we're seeing here is the last of those three where the vortex line is ending on the planar surface or the wall and the vortex then moves into the engine and then as we go off the snow the vortex disappears although it really is still there. This is another 777, this is on takeoff from Paris Charles de Gaulle and watch the inlet to the engine here, again the Boeing 777, you can see moisture because of the low pressure zone that is created on the inlet to the engine and depending upon atmospheric conditions this was kind of a rainy morning and consequently there is high humidity in the air so you can see the moisture and then watch on takeoff, watch above the wing and there you can see the low pressure zone above the wing and again a lot of moisture forming as the pressure goes low vapor forms in the air and you can then visualize it. This is a Boeing 767, it was a flight between Calgary and Norita Airport Tokyo or Japan and you can see here visualization which is quite rare, it's sometimes hard to see this but there is a shock wave that you can visualize through the optical technique called shadow graph, it just happened the angle of the sun was such that you could visualize the shock above the wing and there you can see the shock moving back and forth due to the changing of the inlet flow on the wing due to the turbulence as the aircraft is flying and so the shock wave is not stationary it moves back and forth in response to that. This is a flight from Reykjavik to Paris and what you can see here is an early morning flight and so the light conditions were quite favorable but you can see the contrails forming behind the jet exhaust so there is water vapor due to combustion and the water vapor the particles they form little droplets and then they freeze very quickly and that's what we call the contrails and so here you can see the contrails forming behind an aircraft flying over Calgary and if you watch what happens those contrails break up through the Crowwind stability. Again with the home holds vortex theorems the vortices have to close on themselves and they break up. This is a 747 on landing in Hong Kong International Airport you can see the leading edge trailing edge flaps fully deployed and then finally this is a 757 aircraft landing in Paris and you can see the landing gear deployed the flaps through the shadow and then as we turn to look at the wing the spoilers go up and the thrust reversers at that point would be deployed and the flaps are fully deployed as well in order to decelerate the aircraft. So those are a number of applications showing transportation applications of fluid mechanics and consequently we can see that there is an awful lot of fluid mechanics everywhere within those flows. The next one that we're going to look at is going to be buoyancy driven flows. Buoyancy driven flows are sometimes used in industrial processes sometimes they're used for other things so let's take a look at buoyancy driven flows. Here we have a clip of a smokestack in the middle of Medellin Columbia and this was a very very calm morning and consequently there was not a lot of turbulence within the planetary boundary layer and consequently you can see the smoke going straight up. This is a natural draft cooling tower in Germany. There you can see that it is being driven by the buoyancy of the hot gases the steam rising. This is a flame at a restaurant at Planet Hollywood in Las Vegas and the restaurant's name is Burger and you can see a little bit of a flame instability. This is with high speed video so it's kind of neat to be able to see that flame ripple around but it is caused by buoyancy. This is something that I like doing during the summer and barbecuing in the backyard to get to listen to a little bit of cold play here and you can see due to the index of refraction variations as the air heats up behind the barbecue you can visualize it and then as you go higher up in the barbecue there are some byproducts of combustion coming out which obviously would have different index of refraction as well and consequently you can visualize the flow. This is another buoyancy driven flow this was in front of the Sony building in Tokyo Japan and here you can see the heavier mist descending and then it hits the ground and then moves off to the right in a little bit of a jet and that would be another example of a buoyancy driven flow where it is going downwards instead of up and finally this is in the Toronto Pearson International Airport a neat little display they have there. The bubbles are causing circulation in this flow cell and the cubes you can see them moving due to the injection of the circulation due to the bubbles rising and that would be due to the buoyancy of the bubbles that was causing that to rise so that's a second type buoyancy driven flow the next one we're going to take a look at our atmospheric and oceanic flows so let's take a look at atmospheric oceanic flows and we're going to begin this is a video clip of Cascade Mountain in Banff which is near Calgary and you can see the wake of the mountain that the wind was coming and you can see the snow coming off the mountain you get a recirculation zone there this is a wind turbine that is being propelled by the wind in the planetary boundary layer this was in Germany beautiful apparatus structures that we see unless people live near them they sometimes complain but I find them beautiful this is an aquarium you can see a fish flowing through and bubbles and and this again is a high-speed video clip and what we're going to do in a second here we're going to zoom in on the bubbles and bubble flow is a very very interesting type of flow very important for the oceans because that's where the oxygen comes from but you can see the bubbles are flowing right behind one another and they get entrained in the wake of one another a very complex pattern and these are jellyfish these jellyfish are in the Maui Aquarium a beautiful display that they have with hundreds of jelly fish inside of this and and you can see the jellyfish moving around the propulsion that they have a very different type of propulsion system but very much fluid mechanic related and so a bio bioengineering inspired flow you could study the jellyfish and that as well would be fluid mechanics that you get to see in action there so that is atmospheric oceanic flows the next one we're going to take a look at flow instabilities now these are things that you don't always find and what's it all you do and it's kind of interesting when you do find them and so I'll show you a couple of examples and I've come across over the years we're going to begin at a park in Guangzhou China Bayou Park I believe was the name of it and here is a little fountain that they had and and if you listen you can hear the instability and the wind direction was from the right and when the wind would calm down and stop the way we go away when the wind slows down and it goes away for a very neat ability this is a Ford Fusion car and this had a cavity mode when you drive it and you get about 40 miles per hour it drives you crazy due to the noise but there's vortex shedding off the front of the window and then it impinges on the back of the window so listen to this you slow down the vortex shedding on the cavity gets lower and lower and so it goes away so those are two examples of flow instabilities the water park in China and then the Ford Fusion and and obviously that's not something that's desirable usually the engineers try to avoid it but sometimes you can't avoid it given the particular design of a vehicle and sometimes a sunroof will do that as well and that's why they sometimes have the vortex and break down device at the front of the sunroof to get rid of it last thing we're going to take a look at entertaining flows and so fluid mechanics can sometimes be highly entertaining I think it's always entertaining but let's take a look at that that's a moment and mark this is a room bubbles you can see the kids having a lot of fun trying to pop the bubbles and once in a while the bubbles do escape and you can trace and see what the fluid flow looks like and some bubbles aren't as lucky but this is video and we can fix that and bring the bubble back to life that this is Las Vegas the Bellagio Fountains very very impressive display of fluid mechanics at the Bellagio Fountains so that was some entertaining flows we we saw a fountain with the ball we saw bubbles in Rome and we saw the Bellagio Fountains so there you can see a number of different reasons of why we would want to study fluid mechanics we looked at transportation we looked at buoyancy driven flows a lot of industrial applications atmospheric oceanic flows very very important today with all of the concern about change in weather within in the earth's atmosphere flow instabilities those are sometimes rare but neat when you find them and then entertaining flows fluid mechanics make people happy and consequently I hope you can use this video segment as being a way to provide you with motivation for why you should study hard when you're studying fluid mechanics it's a very fascinating subject has many many applications in our everyday lives


Hi y'all welcome to a week in my life vlog I haven't been able to film these are my favorite videos that I post so we're starting off on actually not even a sad note we're starting off on a good note due to what I thought was happening I'm gonna try to share the story very quickly spoiler alert okay you guys follow me on Instagram you saw she's sitting right next to me I've not left her side all day I had the scariest night like literally in my life last night I woke up at midnight she was next to me I like touched her she shrieked and then I moved her and she couldn't walk like she was just wobbly and falling everywhere and I freaked out she went and hit under the bed which scared me even more I literally threw the mattress off the mattress topper grabbed her we sped off to the vet I think we're at the vet but the emergency vet by like 12 10 we get to the ER they take her vitals she's fine but they're like we're gonna hold it right now until you can get into a room with her because we don't know she's gonna see you or something long story short after three hours there two and a half hours they tell me after like literally I mean I'm thinking the worst and I'm seeing the worst she comes into the room I'm like terrified out of my mind comes into the room and she's like trying to rent to me she's just falling I'm like oh my god I'm literally gonna throw up I'm literally gonna throw up no one that I know is awake my grandma wakes up and I'm like oh my god no no no cuz you know it's a big bad sign when your grandma wakes up and tells her that like she's worried something bad happened all that to say they think she's IV DD or FCE I'm thinking it's IV DD which is treatable all thing I'm thinking like that and I'm like is she ever gonna walk again and they're like oh yeah with surgery like I wish that they would have said that from the beginning they didn't she's fine so she's on lots of meds I've been with her all day I've tried to get her in as early as possible the earliest I can get her into a neurologist Thursday it's Monday she's on two meds right now she's supposed to win three and I'm going to pick up the third one because I think her script finally arrived did you guys know that you can get dog medicine from CVS anyways my story short it's happy because Coco is going to be okay but it was terrifying and I am just so happy she's gonna be okay anyways that has been my Monday it has been the Monday of all Mondays it is currently like 5 30 p.m. it feels weird to be in my car on a weekend I once it's getting dark because you know I don't leave my house just on mom duty today but I hope you guys enjoy this week of my life vlog got a lot going on and we're gonna get to the bottom of this with Coco on her health journey she's only seven which not that old like obviously I know it's not young but like she's a more key she's small you know everyone let's give Coco let's send her some good thoughts I ordered flour child for dinner they didn't even have the script ready for Coco but I did pick up a crate I have a new crate coming tomorrow but I won a one for tonight so I picked one up from my dad's house and I just made it a little home for her oh I wanted to unbox very exciting Margot's newest birth business no particular order so cute a handwritten note love her so much oh my god like this packaging is sick it's just so perfect Margot Lee love her so much whatever your friend starting businesses you need to be the customers like don't be the people who are like wanting free stuff it's very important to support them also with really really hard so anyways that's why that's like one of my like main things in life because it's very important and I think it's just different to when you have like your own business and you realize like this is so cool I love journaling as we know so I'm really really really excited it's just like amazing oh my god I'm so excited it's a journal with so many different prompts so cute oh my god congrats Margot so exciting this crate is obviously a little bit big for her but I started filling it up and she has like walked into it herself she's not a huge fan of crates but it's very important that she's resting in a crate during recovery and also just like currently so hopefully she ends up loving this also my new phone case and water flower like it is so cute I don't remember the last time I bought like a cute phone case or a phone case from wildflower like I think been like five plus years I don't even know but this one is so cute so I had to get it I got flower child for dinner I need to record some stuff and send it in every episode for the next like month or minor of the year is due tomorrow so need to get to work on that it's almost seven I might just send in like this week's and then do the rest tomorrow I don't know I just this has been a day it is 9 p.m. and I finally finished sending in all the episodes through like the first week of January which was a lot at once but they're all sent in so I'm done with the podcast everything is sent in on my end as far as episodes go through the first week of January and it is December 12th so I'm feeling really on it I do have like meetings and stuff for the next two weeks there's other things we're doing and like booking and stuff for the new year but as far as the episodes they're all sent in I feel very accomplished I'm also stressed because it is raining outside and Cocoa gets scared in the rain she needs to sleep in her crate but she like has to sleep on top of me when it's raining so this is not set up well it is the next day it is almost 1 p.m. I have been on dog Judy all day I feel like this is the most boring vlog ever I do have an aqatar of course I don't be like you say aqatar you say a quart of thorns and roses update for y'all I got a package from skims that I ordered I ordered this red dress to wear to our like Santa bar crawl this week and it came the day up so I don't ever wear that I don't really like red much I just got my nails done I it canceled my workout and anything I couldn't take Cocoa to she's been running errands with me all day we picked up her prescription with a star box got her nails done we dropped fits off at the groomers pretty soon she's gonna grab a mic and start working with me I ended up staying up like really late last night getting all the work done that I needed to do today I had like a wave of energy I really want this week to be like a little more chill and I wanted to do more festive things but I'm just too afraid to leave Cocoa by herself so maybe I'll watch some movies from home or just read I just wanted like a chill cozy week this weekend we're going to the lake my family's Christmas like little trip we're going to our lake house and I got myself some cute skimmers pajamas I figured these would be perfect for the lake house all lengthies they're really really really warm and they're like so cute I love brown and black together I'm having really bad allergies like I think I'm sick now I got a whole new coffee set up I just replaced this espresso because it's just never gonna work I got a new frother which I didn't really need so I am looking at the one that I have right here I don't know why I ordered that I think he came with it and then new Nespresso pods and we're gonna have a new coffee situation promise this week is gonna get more entertaining we have so much going on we have a pop-up Alyssa is getting engaged my cousin on Thursday so it's gonna be a really good time anyways I have to give Coco all of her meds I'm not okay also I'm a pharmacist in the back that's all Coco spends as you guys know I've been reading a court Florence and roses the first book everyone is like so obsessed with it I read the first half of it like fine I got to 50% last night and I was like this is so where I like so not into it and then at 50% it really picked up so I'm gonna go finish that today have a little cozy day and I think I will end up really liking it we'll see I don't know if I'm gonna like read all five or if I'm gonna like read immediately after okay I gave Coco all of her meds and she is really wobbly I think it might be a side effect of wobbly or of being drowsy I'm not really sure but just keep me close eye on her oh no let's okay let's lay down let's lay down girl let's just stay there I ordered some ramen I don't feel great at all like literally at all I have a cold so I feel like a man but I just don't feel good so I ordered ramen food I'm in the middle of reading I'm gonna catch up on the cool little reality TV show gonna stop vlogging about this soon but I've literally been sobbing because the new men's Coco's on our muscle relaxers and she like obviously couldn't walk again and I just freaked the fuck out like oh my god I mean it is a side effect and I mean it's a muscle relaxer like what do you expect she really looks like coconut from American girl that's what she's like after but thank God my sister's gonna help me later I think I'm just gonna end vlogging for now because this whole vlog has been really boring but later this week it's gonna be better tomorrow it's gonna be better so don't worry it is now Wednesday this has been the biggest mess of a week I wanted to go to festive stuff the past two days couldn't do it tonight I am hosting the Bumble BFF like supper club at Ficcini I'm sure there's other people who are hosting it I just don't know who else is but like seven of my friends are coming I got to invite them it's gonna be fun we love Ficcini I'm on my way to go get a blowout I'm packing my bag right now the bag that like literally holds everything including my candle I am on like so many meds right now sometimes when I lay around my house for like days at a time because I only do that when I'm sick I like convince myself that I'm sick and I'm not sick you know I have a lot of meetings today I had the Bumble BFF summer club tonight I have some brandals I need to film and post and sent in I'm not leaving a girl alone even though a lot of dogs live with IVDD I know but I am just not leaving her alone to her dog sitter is gonna come here with the dogs while I'm getting my blowout and then tonight she'll also have a sitter I got a new crate for her like a smaller one that's more of her size so I think I'm actually gonna set this up really fast before I leave also I tan last night my face looks crazy cuz it hasn't like washed off yet but like my nut moment of silence I also bought athletic greens myself not sponsored and in days like today it's because in Texas the weather will go from like 70 degrees to 30 the next day and because of that I get sick with the weather dropping so much not like really like I just get like a bad cold but I will say they've been worse than normal I honestly like don't mind the taste of this it's whatever I mean I also like green juice I hate that I mind but I really don't mind this blowout is done it's I got the dirty martini which I never get this looks like literally nothing like the dirty martini looks on their thing but it's going to fall and like I said I always look at crazy at first because it'll fall I also booked an IV because IV is always helped me and I just have to get past this cold I also have a great got in the middle of my nose guys they it's actually comical it's comical but I have got to be on my a game so I'm gonna go get this IV I can work from getting my IV and then hopefully things will start to pick up I am feeling better it's just like I feel you can hear that I'm really nasally like it's just like a bad cold so and like I feel stupid for being like a cold bothers me but like I just don't feel great you know at all one thing about me is that an IV is going to cure all I feel so much better I don't know if it's placebo I don't know if it's reality I don't care okay I feel better obviously I still sound not great but I feel so much better so I'm heading home I have a meeting with your media with Geneva I have to shoot skims and plan B and then I have the dinner tonight I've said that so many times in this vlog oh I finished a quart of thorns and roses for the aqatar series you guys have got to tell me if it's embarrassing to be saying like the acronym like that like I just don't know I gave it a review on my ke book club my bookstagram if you will and I I got some people are a little mad at me I think I knew going into this series that I was gonna commit to probably the first two books because everyone says the first one's like okay or a lot he will have said the first one's okay but the second one is where it really gets good listen I'm not a fantasy girly but I did love Twilight okay and that was like my favorite book growing up I also love the Hunger Games diverge like all that stuff I was into okay so I was like maybe I do like fantasy more than I than I think I do so I read the first one and honestly the first half of the book I don't even know if I really comprehended it because I was just like not into it like I felt like it was just slow I didn't really get what was going on I was like who is this like I don't know I just like wasn't like loving it but I wasn't hating it I just wasn't like hooked the last 50% or the last half is where things really picked up and I ended up enjoying it a lot more but even then I felt like at times I was like alright how much longer I want to just be done but I did like it I rated it a three and honestly I was just because I'm like it's not a book that I was like dying for three is not bad and like it was it was okay like I'm not like super into it but I think I could see myself getting into it with a second book I've done that in other series too where I didn't even like the first one for some reason I read the second and then I loved it so I will be reading the second one don't even worry but let me tell you these fans are really not having my review they called me stupid and they called me dumb and you know what guys honestly I get it I feel that way too when people review my favorite books so wrongly but like everyone has different tastes and I am not the like demographic that would typically like this book you know what I mean but I do know that the book is known as like even if you don't like fantasy you like this book you know I mean so we'll see I would love to just get like sucked into a series especially next week because I'm getting my chin done so we'll see we will see also I don't know if y'all have even seen my nails up close I got red with chrome I saw someone else do it on like tech talk or something weeks ago and I was like this is what I'm gonna do I did get red nails cuz the red nail theory like a month ago and I feel like I liked it okay I'm not I'm not like a red girl just like not my color but I do really like these nails and I feel like they're festive you know I really hope this IV just like fully cures me and like my nose as well yeah my hair by the way it's really interesting like I just don't understand like it's not at all what I asked for but I feel like it's gonna fall well we'll see I finished my meetings we went over 20 23 merch I did say that it was gonna be the end of bramony housewife but I just don't think we're there yet I've heard y'all's request for the navy bramony housewife set to come back and I'm doing what I can to get maybe like a little core collection if you will my body feels good my head hurts but it's like a like a headache from the cold it's like you can take the girl out of LA but you really can't take the LA out of the girl for the record I'm taking dayquel and stuff as well thank God I finished all my recordings for like the rest of the year those are due this year cuz can you imagine if I sounded like this okay so I have two shots I don't know what is what and listen people are like oh girls but if you can take a shot of tequila you can take this okay whoo tequila is easier than these guys look at right now I don't know if I don't remember what I'm vlogging this week but he got a haircut and I mean he just looks so handsome he looks a little bit funny but he looks handsome second shot it's currently 4 p.m. I'm gonna shoot some skim stuff the girls are coming at 6 and then we're heading off to focini for dinner I'm just really grateful for my life I was thinking about how earlier this month they felt like it was a failure and then I have like my year recap meetings are like one of them and I was like I'm not a failure so that's my update not that I should let that define if I feel like I'm a failure or not but I was just being a diva I think is what I was big okay next one this one looks a little bit um yeah that was a lot easier okay I've mentioned this before but I need your help I really want to do a drink so I'm working with slash I'm a chair on the board or I'm a chair for mature for the family place I'm new to this I don't know the right way to phrase this one and three women in Texas are abused which is obviously like crazy it's every form of abuse just really sad anyways I'm doing a lot of things with them next year that I really want to just get the ball rolling on and just waste like make money maybe get more people involved maybe make people aware like things like that and you know since I've really truly like a book or a drink influencer I would love to have a drink in like honestly the rustic would be a dream or where else tribal is like my number one like my good morning drink I would love to like have a drink there that weekend that's like the Kenzie Elizabeth drink or like the week or the month or whatever to where it's benefiting the family place so you go in there and like all of their like profits for that drink goes to the family place I would love to do that but if you guys can think of any good places in us slash if you know or work or live in us or like have any sort of connections let me know because I really want to do that and I just I just to figure out who through anyways I'm drinking my juice is actually this one's not bad well I'm gonna give you all a little garden update so obviously we're really doing something here here is my kale feel like it's getting really bunched in the middle we've got some arugula it has been pouring like the past two days it rained so hard then over here we have some onions this is actually carrots like things are really are really happening here hey guys don just FaceTime me okay so look at what I'm wearing was taking my skims content and this is what Dom was wearing I literally had this on 30 seconds ago yeah and I was like I answered and you couldn't see it and then I go dumb yeah so we're just two skims girlies guys Coco's doing so much better thank god she really really scared us she really did I really can't over how can I focus is what are me and all the girls are going to a bumble bff dinner all your faves Lauren Tess Marissa was going to which you can't all the girls um Jessica Janelle yeah sorry damn wish you were coming there you go hmm okay right guys we're all off we go I could dream oh I was gonna say no flash it was so perfect over here over here it's a Chini my god I can't deal with it I can't deal Lord is thinking everyone for coming to her event love that I get from Dallas is just out for nothing like it the bar crawl the Santa bar crawl it's actually so much fun and I got some like Santa turn 25 and now I get this what a week what a week this is how you know you've just given up this new wagon thing is great oh my god oh too soon do you think it's because of me and the engagement chicken everyone is replying this right now to be fair I fully knew that you were gonna engage when I made that chicken I knew the date cuz I had already played but but I will take the credit thank you very much thank you my hair is very curly I straighten my hair like every day but so in the rain like I'm not going to look great it's gonna be very ugly so I'm like whatever I'll bring an umbrella forgot my umbrella get there it's pouring rain and he sees me and he's like hey you walk into this building and then out of the building into the ice sculptures I'm like doesn't even acknowledge that it's outside I'm like I literally tried to tell you but I didn't say anything okay I'm from Alaska like I've seen plenty of ice sculptures so I'm like are you done like looking around like are you good
