Hi, my name is Sandeep Gupta and I'm the Product Manager of TensorFlow JavaScript. Today, I'm really excited to talk to you at the Chrome Developer Summit about machine learning and JavaScript. As a web developer, you may have felt that all this buzz and excitement about machine learning seems to require Python and how you as a JavaScript developer can jump in and use machine learning. I want to show you that now machine learning and JavaScript is real, powerful and useful and you can do some amazing things with it. Earlier this year, Google released its first ever AI-powered Google Doodle. In this, users could synthesize a box-style harmony using a machine learning model running directly in their browser. So in only three days, more than 50 million people use this Doodle to create, save and share their music. A creative marketing team in Google has built a fun interactive experience where users are shown a zodiac symbol and they try to match the shown animal with the shadow of their hand, making that character come to life. Other teams are experimenting with novel ways of making web interfaces more accessible. In this example here on the bottom left called Creatability, people can control web interfaces with gesture such as playing a keyboard with their face motion. All of these amazing examples have been made possible by TensorFlow.js. TensorFlow.js is an open source library for machine learning and JavaScript. It runs in a web browser and can also be used server side and on many other platforms that support JavaScript. You can use TensorFlow JavaScript in one of three different ways. You can run a pre-trained machine learning model in your application. You can customize a pre-trained model by retraining it on your own data or you can use the lower level ops API to write a new model from scratch directly in JavaScript. There are many reasons why you may want to consider using TensorFlow JavaScript. First of all, it allows web application developers and JavaScript developers to use machine learning directly in their applications and it's really easy to get started and be up and running. With only a few lines of code, you can load our library and you can load a pre-trained model such as the body pics model. And this is a model that allows you to do person segmentation on an image. You create an instance of the model and then you call its estimate person segmentation method on your selected image. And you get back a JSON object which contains the segmentation mask which can then be directly used in your application code. That's all there is to it. So in just a couple minutes, you are up and running and you're using ML in your web application without having to deal with concepts such as tensors, optimizers, losses, etc. TensorFlow.js can be used client side in the browser and other browser like platforms. This has many advantages. You get all the benefits of the interactivity of web as a platform and users can use directly microphones and webcams and other sensors that are attached to the browser. Users don't need to install anything so your application becomes instantly deployable and shareable. Another big benefit is that user data stays client side and this has very big implications for privacy for applications such as healthcare for example and it also helps reduce latency and server side costs. Finally, we support GPU acceleration through WebGL which gives it excellent performance out of the box. Although in this talk, we are mainly talking about browser use cases, I should mention that TensorFlow.js can also be used with node.js server side and this is very useful for enterprise applications where node is heavily used. Another natural question to ask is how fast is it? Well, it turns out it's really fast. For example, on mobile devices running inference with an image classification example using the mobile net v2 model, you get real time performance with 20 milliseconds inference time. And on server side, we have performance parity with Python based TensorFlow. So to help you get started, we have a collection of pre-trained ML models for common ML problems that we have prepackaged for you. These include use cases such as image classification and object detection, detecting human pose and gesture, audio models for recognizing spoken words and building speech command interfaces, and text models for text classification, sentiment analysis, toxicity detection, etc. It's really easy to use any of these pre-trained models with our high-level wrapped APIs from our hosted scripts or you could install from our NPM packages. Using these models as building blocks, applications can be built for a variety of use cases. These include things like accessibility, AR VR experiences such as virtual product trions, conversational agents, and moderating user-generated content on your websites. So these pre-trained models are a great starting point. Often, however, in real life, you need to customize these models on your own data. So one way to do this is, again, by using the power of TensorFlow, running directly in the browser interactively and using that to train a model on your own data. Let's take a look at how easy this is. So in this demo, I will show you how to use Teachable Machine to train a custom model. So the MobileNet image classification model is already running in this browser session, and we will modify it to recognize symbols for rock, paper, and scissors. So we're going to output the word rock for the first class. We will output the word paper for the second class, and we'll output scissors for the third class. Now let's record the training images for these three classes. So first, let's record images for rock. So I'll hold up my hand like this. Rock, and now let's record some images for paper. And now let's record some images for scissors. Paper, scissors. And now our model is ready for inference. So let's take a look. Rock, paper, scissors. Paper, rock, paper, scissors. So that's all there is to it. In a few minutes, you have a custom model trained in the browser. So far we have seen the capabilities of the library. Now let's take a look at some use cases. Modiface is an augmented reality technology company based in Canada. And they have used TensorFlow.js in the VChat mini program platform to build a beauty product virtual try on application for L'Oreal. Using TensorFlow.js, they were able to deploy a custom model meeting their model size and speed constraints for this application. And you can do the same thing in browser extensions. To showcase how you can enable amazing user experiences with the power of TensorFlow.js, we've built an application. Here we are running a state of the art machine learning model to track users lips and face movement. And we use that to lip sync to a song and score how well you do. You get awesome real-time performance that enables this application. And because there are many JavaScript visualization libraries out there, we can use them to add on some cool special effects. So let's take a look. Companies are using TensorFlow.js for a variety of purposes, whether it be for internal tools for experimentation and visualization at Uber, privacy-preserving client-side application at Airbnb, and also offline mobile device use case for field use by IBM Research. Lastly, I want to highlight that the success of the library is due to our amazing contributor and user community. The library continues to grow in users and popularity, and we are really excited about the amazing libraries that the community is building on top of TensorFlow.js to extend its functionality and applications. So thank you all. This was a quick intro to TensorFlow.js. Please do check out our website where we have more demos and examples and getting started guides and resources. And also, from there, you can join our developer mailing list. Thank you so much for watching.


Before we get into the video, people, I am giving away 11,500 Apex coins every single month. To beam with a chance of winning them, make sure you're subscribed to this channel and have that bell notification button ticked. Drop a like on the video and leave a comment down below. More details on the giveaway are in the video description. What is going on guys, welcome back to the channel and I do appreciate you being here. Today I bring you another Apex Legends video and today guys, I bring you the latest news surrounding the game including Respawn commenting on cross-platform play, Apex Legends on Switch, White Seams, Respawn have been silent since the release of Season 1 in regards to many questions people have been asking and also checking out a few more details on the next Legend, Watson. Okay, so last week I spoke of new files fan regarding Watson and her abilities. A render found within the game file showcases something that is called an electric fence, which is a part of Watson's arsenal. While there's more info on these fences, it seems as though Watson is able to link to these fences creating an electric fence that only she can climb, that only Watson can climb, so it basically creates an electric fence much like the name suggests so it kind of makes sense as to why it's called an electric fence because when we first got this render we saw this pole, a lot of people were kind of confused but now you can link two together, probably there's a certain radius at which you can link two together, probably the width of a couple of doors, so you place one down, place another and it will create maybe an invisible fence that until you walk through it you'll get tasered, you'll get shocked, you'll get fried, but these fence it also seems that only Watson can climb over it or climb it, so I can't wait to do this in-game and learn more about this, should be fun times people watching those people fry and if any more details does land on Watson you guys know I will have you covered right here on my channel, I made a video the other day of when I think she will be released into the game along with a new event and a new weapon, if you want to check that out you'll find it linked within the video description. Okay so moving on, a very recent video of response Drew McCoy, the project lead on Apex Legends, he's answering the community's questions on the game, the whole video can be found linked within the video description if you do want to check it out, I mean there isn't much in terms of news about the game besides what I'm about to cover which in all honesty is just basically the insurance and a couple of things we want to see, first thing being cross-platform play, so although Drew doesn't confirm it's common, he states it's something they are very seriously working towards making happen, as he understands us as players and as a community we have many players and trends on other platforms that we'd like to play with, so although he doesn't mention any specifics he does confirm they are a word of fact we want to see this happen, also Apex Legends on Switch, he reassures he is the Nintendo community, as people want to see this on Switch, he states he has nothing to mention but states that respawn team are working on many many things so basically stay tuned for updates. Now I have a Switch, I honestly don't see myself playing Apex Legends on it but hey I guess there's many people out there that would, so hopefully for your guys sake we see this happen, I mean if Fortnite can run on it I'm pretty sure Apex Legends can run on it too. Okay so moving on and in reality since season one kicked off respawn have been a little silent on the future in regards to new content and to be honest I ain't surprised that they've just released season one and they about to pass, well I wouldn't say just released I'd probably say month and a bit but they are bound to be a little quiet but because the season pass didn't live up to expectations many had, people were left having many questions relatively quickly, questions on things such as new skins as many were not introduced with season one, in fact were any introduced I don't think they were, new game modes, new features, new weapons, many many other things, I mean if you go through Reddit you'll see there's so many people upset with the battle pass and the fact that season one really didn't introduce anything new in reality and it's the same if you go through Facebook, if you go through Twitter, if you go through YouTube a lot of people are unhappy. Now respawn dev a few days back replied to a post on the issues many are having and he stated the following, to answer the first question because the artists that make the skins and the operations folks who update the store don't implement gameplay nor are they in charge of game direction as for anything else there's far too much there to answer individually and a lot of it I'm not limited to answer, the best answer I can give you is we will continue to support and improve the game to the best of our ability unfortunately there are far more things for us to spend our development time on than there is time so we have to prioritise. In the end that's going to leave someone unhappy because what they feel is important isn't prioritised as highly as they think it should be that's just reality and we can't make everyone happy as to why I don't give specific answers about unannounced or requested features like alternate modes far too often it's unwise to do so just mentioning this kind of stuff gets taken as a promise the timeline starts the moment it's mentioned and everyone has a different expectation of what's a responsible timeline and many people heavily underestimate what is required I'll give you my somewhat clinical take on how this stuff tends to go if I were to say yes feature x will come to the game some day aside from instantly becoming a promise which we are now obligated to add it would likely get picked up by blogs and gaming news sites posted as response says x is coming to apex and then dependent on how those articles are written they're going to set expectations incorrectly for a lot of people eventually people would talk about how respond announced x ages ago saying that it's taken too long or speculating about why it's been delayed a lot of this can be helpful by careful wordsmithing but even that can be taken out of context or misquoted like a bad game of telephone leading to the same issues so I'll leave that to those whose job it is and post what I can when I can in my free time hello sunday afternoon and after reading what he said people I fully understand his post and another thing to mention in regards to his posts on apex legends his reason is not to disclose the future to avoid expectations is actually what allowed apex legends to explode in the first place on the promise over the liver I feel they 100% learned a lord from season one and as I've stated in the past most of the season one content we had was already made content I don't think they fought the game would blow up the way it did but it did and when season one arrived many of us were left a little underwhelmed I don't think that will happen with future content and like I said he doesn't want to balloon expectations on the future because many of things get taken away at a context and the hopes of people are shattered when said things actually become into play and they aim what was overhyped on silly news sites which takes the smallest of details and blows them up into 3000 word news articles so I truly understand his point and I actually think it's better for the game going forward yes many things about them being silent aren't great but in terms of what we want and what we want to see from the game going forward all because they ain't dropping details on new things to come does not mean they ain't coming I believe and like I said I made an entire video on this point and what is coming I believe on April 30th not long away that video is linked in the video description if you do want to check it out I'd expect a new legend a new weapon and possibly a new mold but hey my message to you guys would be just be a little patient respawn really haven't had a game explode like this before I guarantee you guys we will get some good shit soon and just because this respawn devils replied to a post saying he doesn't want to balloon expectations because obviously like he says once he's get out into the public eye people do all the hype things and blow them out of proportion and when the content does drop it leaves people underwhelmed I mean season one you could argue wasn't blown out of proportion we didn't know really anything on it but when it did land it didn't develop two expectations but like I said I believe that's because season one was mostly already made content they didn't believe the game would explode the way it did but I guarantee you guys season two when that drops and the lead up to season two which I speak about in my video which is linked in the video description I think will be great times for apex a legend so just be patient guys but on that note we have come to the end of the video guys if you enjoyed it even like we'll just have out if you're new around here and enjoy daily apex legend videos be sure to subscribe and if you never want to miss a video I upload you can turn notifications on by hitting that bell button but guys thanks as always for stopping by hopefully you enjoyed the video and hopefully I will see you on that next one


Now, the presidential candidate of the Labour Party, Pito B, has urged Quarra residents to shun ethnic and religious sentiments as the general elections draw closer. He made the comments during the party's residential rally at the Metropolitan Square in Eloran, the Quarra State Capitol on Monday. I have to tell you, I know. But I do not know why we like to understand. That is why we are doing what we are doing. Remember your own future. Remember the future of your family. Remember the whole day in Nigeria. Only that day and I say vote for correct. All your votes say we can find corruption. And we will do it because we must make a government want to reform poverty. So, guys, stop all the problems of this country. Be huge. The women, this will be your government. So, you get notified about fresh news updates.


Well, what I'm going to tell you now, everybody pay attention, is dream characters don't wake up. You will never find a dream character that wakes up, because the definition of being asleep is that there are dream characters, or that there ever were. You see the ego generated them, and so if the ego generated, whatever the ego generates, which is the dream characters, they don't wake up. They're just figures, they're just images that are projected onto a screen, and the only thing that awakens is the mind. The very idea that you believe in these characters is the definition of sleep. So there's only one mind, and there's only one dream, and your only responsibility is to be happy and joyful and realize you are the dreamer of the dream, and no other cause does it have. So let me go deeper into this question, you are the dreamer of the dream, singular, there's one dreamer, there's one dream. The ego made up a trick to keep you from experiencing the simplicity of salvation, and Jesus talks about this pretty late in the text.  So there's the word secret. Everything in the unconscious mind is pushed out of awareness. All that darkness, all that anger, all that hurt, it's almost like you sealed the dream, and it was sealed the darkness by making a pact with the devil, swearing that you would never go down and look at that premise. And Jesus is saying there's nothing but light and love under that hatch.  God is not angry. God would never punish you. God is pure love. There's nothing but light if you go down to that fourth obstacle, fear of God's love, and you go through that hatch. You'll spring into heaven if you go through that hatch, but the ego doesn't even want you to come close to that master switch, doesn't want you to come close to that release point, because if you open that hatch and it's all light, guess what? There's no ego. Great love casts out fear. If you open that hatch that you swore never to open to the ego, you're just going to find out that there's only light.


So today is Halloween because I like multiple choice choose your own adventure you guys at home get to you know Let me know what you think. I'm gonna let you guess what I am today. Am I a Japanese person be a Moroccan princess and my C from the Brady Bunch or D Did I not have a costume at all went to my mom's house and begged for something random I could put on the kind of look like a costume and ended up with this Hey there you beautiful young people This is magic versus logic sex love and relationship advice for generation y with a little bit of a twist How it works is I read out a question and then I answer it from two perspectives one from the head and one from the heart And then in the comments section below you guys are going to thumbs up magic or logic depending on which advice you think the Questioner should follow this week's question comes from Kathy and she writes I am finished college and still a virgin the older I get the harder it gets to tell people I've never had sex and now with snapchat tinder and other social media sites that all my friends are on that seem to Revolve around sex. I'm feeling like more of an outsider than ever How do I tell people about my decision to wait without being judged or excluded? One of the things I noticed right off the bat in celibacy is I had more clarity I had more self-worth and more peace of mind and it was just a lot more relaxed and sure of myself The average North American will lose their virginity around 16 or 17 years old So if you are 20 or something mid 20s or so it's understandable that you might be feeling left out or left behind in some cases I can relate to this. No, I'm not a virgin I wrote a book on sex But what I am is I don't drink and when I first started going out with my friends the clubs and they were like hammering them back I kind of had to nurse this water and just hope people thought it was like vodka all night long And so I really just came into my own decide that this decision was for me I became very confident in how I said that because if you're saying it all like And there really is nothing to be ashamed of the stats are truly on your side There's a really great study done in the family journal of psychology They found that couples that waited to go down the aisle before they got into the bedroom ended up having a 15% higher overall satisfaction with their sex life and we're 20% more likely to be happy with their relationship In general like that relationship.  It's also a great experience in terms of how to be good in bed for whenever you do decide to be with somebody down the line It's the best teacher and I have to assume that if you're waiting to have sex It's because it's actually important to you that it means something that when it does happen You want to be prepared and you want it to be special so with that being said you should have no problem on Reading about it researching it immersing yourself in it. You need to be freakier than the freaks You have to know how many nerve endings a clitoris has what's more sensitive the base or the top of the penis? What's the female prostate? Where is it? What does it do? Does it really even exist familiarize yourself on all the topics? Anatomy mental emotional social aspects of sexuality that way not only one Will you not feel uncomfortable the topic comes up because you can chime in but to you and yourself will feel a lot More sexually fulfilled for further reading. I found the perfect book It is so on point with great reviews the title super long So I'm gonna read it. It is called sensual celibacy the sexy guide to using abstinence for recharging your spirit Discovering your passions achieving greater intimacy in your next relationship by Donna Marie Williams So now it's up to you guys to decide how do you honor your decision to be a virgin in a hyper sexual world? Without being judged logic you stand firm and confidently on your decision no excuses no explanations necessary Except for one it is my damn decision and I'm proud of it magic If you don't want to be pegged as an awkward virgin then don't be awkward Don't let your virginity be the defining factor of your sexuality Make the two very separate in terms of what you do and what you know on last week's episode We asked at what point does online admiration of somebody who you're not in a relationship with become detrimental to your real life Relationship now magic went out last week and there was a lot of great comments and here are some of my favorites This week's email comes from a dude. I know I shouldn't be dancing That's kind of sexist but women just love giving relationship advice to guys I'm gonna take your entire left breast shove it in my mouth to deep throat your nipple


Vice President Kashim Shatima has inaugurated a 37-man tripartite committee on new national minimum wage at the Council Chamber of the Presidential Villa in Abuja. The committee is to be chaired by Bukur Gurney-Aji, a former head of service of the Federation. This is coming barely a week after President Bola-Tinibu approved the inauguration of the committee. The removal of the petroleum subsidy. Barrios committees have been established to examine and make recommendations to the government on major secretion the envisaged painful effects of the increase on workers and the Nigerian population at large. I am pleased to share that action has since commenced on the implementation of the outcome of those agreements and initiatives. The President hereby directs that ministers and head of service of the Federation shall personally attend the meetings. Hello, hope you enjoyed the news.

Members of the People's Democratic Party PDP Inquira state and other loyalists of former governor Abdul Fattah Ahmed this Wednesday stomped the Lorian Zonal Command of the Economic and Financial Crimes Commission, EFCC, to protest the refusal of the anti-graft agency to release the former governor of the state after three days in detention. State published a set tree of PDP Olushego Adirara who led other protesters described the development as gross abuse of power by the anti-graft agency alleging that a former governor is only being persecuted as a strategy to get him to defect to the ruling all-progressive congress in the state. According to the choir state published the secretary of the People's Democratic Party PDP Olushego Adirara former governor Abdul Fattah Ahmed had been denied access to his personal physician and lawyer in the last three days by the anti-graft agency in an attempt to compel him to defect to the ruling party in the state alleging that the EFCC is being used as a tool by Abdul Razak led APC in choir state. We cannot use corruption, corrupt agency like EFCC, especially at the north central zone. But when you want to fight corruption you must follow due process. You cannot keep a former governor, not every citizen of Nigeria, you cannot keep them in detention for more than 24 or 48 hours. Governor Abdul Fattah Ahmed asked E3 of always honoring EFCC, this is not the first time it is surprising that since Monday governor be kept in this custody with a bid and they are telling him please, they are telling him to come to HPC so that this prosecution will be discontinued. We are sending it to them that if EFCC is not putting themselves as a department in HPC, we stand against it. Reacting to the allegation against the EFCC, the Zonal commander of the agency Michael Zekwe said the anti-graft agency is exhausting all windows of due process in its investigations against the former governor. As I speak to you, there's an S.A.N. in there, not just the S.A.N., he has his lawyer. Every statement, we follow the provision of the law, street censors, every single statement he has written, his lawyer is there with him. The lawyer, as I speak to you, is seated with him, he has a doctor and the doctor has attended to him even this morning.


Hi guys, what is up? Welcome to my channel. I am so excited for today's video. I am going to be doing the foundation wardrobe tag. So if you want to see what that is all about, then just keep watching. So this is actually a really fun tag that my friend here on YouTube, Charlotte Hodcroft, she created and it is so fun. I am loving these prompt kind of tags that we have going on. So the whole premise of this tag is that you are given 10 different occasions and you pick the foundation that best fits for that occasion. So I'm going to link you down to her video down below. Make sure you check it out. Thank you Charlotte for coming up with this because I had a blast picking out these foundations. So number one, the first occasion is date night evening event. When I thought of that, I thought of going out for dinner or a movie or both. I find that when I get oily, it really does happen at night. I don't know why. I wanted something that was going to hold up. It wasn't extremely heavy, but definitely gave you some coverage and was comfortable on the skin. So for me, that was definitely the Giorgio Armani Luminous Soak Foundation. This foundation is bomb. It is so lightweight on the skin and that's a big complaint I have about wearing foundations in the evening. I really can't stand when they're too big or I can feel them on my skin. This is not only a really lightweight foundation. It does give you a nice medium coverage. You can build it up a little bit in certain spots. You can't build it up to a full coverage, but this definitely gives me enough coverage. It photographs beautifully. It looks good during the night time and it's just a really comfortable, good coverage. It makes your skin look really beautiful foundation, trying hard, but not trying too, too hard looking. So Giorgio Armani Luminous Soak, I remind in the shade 4.5. So the second occasion that we have is errands.  You're not necessarily looking to do a full face makeup, but you want something. And for that, I chose the Laura Mercier Tinted Moisturizer. This is also what Charlotte chose. And that should tell you how good this is. This is one of my favorite kind of throw-on foundations. It really isn't a foundation. It's a tinted moisturizer.  And you just feel a little bit better about yourself when you wear this. And I love the glow that this gives and it gives you a little bit of SPF. If your skin's feeling a little bit dull or dry, this kind of gives it that pick me up. So I really love this tinted moisturizer. This is one of my favorites. And I felt like I could have put this in multiple categories, but I tried not to repeat. But I absolutely love this. I have mine in the shade 3N1 Sand. The next occasion that we have is Workday Foundation. So everybody's pick is going to be different for this, which I think is really cool kind of depending on what you do. I am a physical education and health teacher. When I'm not in quarantine, I am outside in the heat all day with all of my classes. And if I'm not, I'm in a building and I'm still moving around constantly on my feet all day. So I want something lightweight that's just going to kind of even my skin tone, but also wear throughout the long hours that I'm out. And for that for me, it's the Makeup Forever Matte Velvet Skin Powder Foundation. I love this. I have mine in the shade R330. This is my go-to powder foundation. It really evens out the skin as your oil sink into the powder. It almost turns it into not a liquid foundation, but it becomes more skin light and less so powdery. At the end of the day, I don't look bad. I don't look cakey. I look like I still have a little bit of coverage and it doesn't bother me all day. I don't feel it on my skin because it is a powder and it actually applies a good amount of coverage given the fact that it's a powder. I really enjoy it. It evens out my skin and it really works well throughout my work day with me. The fourth occasion that we have is a wedding. I picked a foundation that I personally will probably be wearing to my own wedding because I love it, but I also wore this to my cousin's wedding because whenever foundation you wear to a wedding, you want to make sure it's going to last you a long time. It's going to look good in any lighting. You know, if it starts off with an outdoor ceremony and then you work your way into the reception and the after-party, which is all late at night, it needs to look good in all lightings, all settings, daylight, moonlight, outside, inside. Every lighting has to look good. In photography, it must look good. It must not have a flashback. And for that, it is the Dior Air Flash Foundation for me. This is probably my favorite foundation. I just think it looks the best on my skin out of any other foundation in my collection. It wears beautifully. It looks good no matter where or when you are wearing it. It is a special occasion foundation, though. That's for sure. It is more pricey. Be prepared for that. For me, it's worth every penny. This is my special occasion wedding foundation. I have mine in the shade 300. My favorite way to apply it is sometimes I just like to directly spray my face. It will get in your hair that way, but if you don't want to do that, get a sponge, spray it on the sponge, pat it in. Really, I feel like this gives an airbrush finish to my skin that none of my other foundations give me. The next occasion, number five, is clubbing. I'm only 24, but it has been a long time since I have gone clubbing. I had to think back to my college days and I was like, what foundations did I wear? And instantly, the foundation that I picked, it's perfect. You want something with coverage because you want to look good.  So you want to make sure it's going to look good. Like you're not going to look as much of a hot mess because of your foundation. You want to make sure you have coverage. You want to make sure it photographs well. It doesn't transfer. And for that immediately, I thought of the Estee Lauder Double Wear Stay In Place makeup. This is what I wore in college as well. This stuff is bulletproof for the amount of coverage that you're given. I love this. It's not going to go anywhere. It's going to look okay at the end of the night. It's going to work well with your sweat. It is so good. Anytime of day, if you're out in the hot summer sun and you want coverage, this is the way to go. And I don't know, for me, when I go clubbing or go out at night, I don't really care if my foundation feels really heavy. I want it to just look good and this looks really good on the skin and it's going to last you all night. So I absolutely love this. I have mine in the shade 2W1 Don. This is a staple cult favorite foundation for a reason because it's going to work and it's going to last. The next occasion is gym slash exercise. Guys, I cannot condone wearing makeup while exercising and working out. I don't do it. I've never done it. I never will do it. I have very sensitive skin and any sort of foundation seeping into my pores is going to cause an irritation and cause me to get zits. I will never ever look out with any type of makeup on. So I passed on this one. I didn't pick anything out. It's not good for your skin and I know people do it all the time but my sensitive acne prone skin, that's a recipe for disaster. That and sleeping with makeup on, I am asking for a reason. Number seven is a festival. So an outside event. The sun's going to be hitting you. You're going to be hot. You're going to be sweaty. You're going to get wet. You're going to get dirty. For me, if I know that's happening most of the time, I probably won't put any foundation on or I'll put just a little bit of powder. But you know what? If you want to look cute, most of the time, I'd rather just start the day off looking cute and if I look a hot mess at the end of the day. If everybody else does, what does it matter? For me, I ended up choosing the Acosmetics CC Cream. I have mine in the shade. Well, I mix light and medium. So I mixed two shades. The reason I chose this is because you're going to look at the beginning of the day. It does add some coverage. You can build it up for more. For me, and this occasion, I would probably try to do as light of a layer as possible so that it doesn't melt off my face and so you don't look as horrible at the end of the day. And also, of course, this has SPF 50. For me, my biggest concern in this was the sun. So I wanted a little bit of coverage to make everything look more even and I wanted sunscreen. So that really does handle this. I would say if you want the full coverage, like you want to look good, go with the Estee Lauder Double Wear. That would be my go-to. But for me and what I would be comfortable with, I would just start off with something light and it's the kind of product where after kind of fades away or you sweat it off, you don't look horrible. So that's why I would go for this. Number eight is Everyday Foundation. There's a few foundations that I was toggling between because I have a large number of Everyday Foundations that I love. But ultimately, I wanted to go for something that I love, that I've worn everyday for years and I prefer a more medium coverage. I have drier skin and I just absolutely love the Makeup Forever Ultra HD Foundation. I have this in R330. This is the makeup that I'm wearing on my skin right now. It provides the perfect medium coverage to the skin. It's really reliable. It's going to look good wherever you wear it to. Whenever you choose to wear it, it's going to last you a decent amount of time. Your skin just always looks better when you wear this foundation. It's really a oldie but a goodie. Like you can still see my freckles and a little bit of acne scarring underneath. But that doesn't bother me. My complexion is overall much more even and much more pretty. I like the skin like finish that it gives. And for me, this is just a really great easy to use everyday foundation. I know it's going to work every time I grab for it. So I like this guy a lot. Number nine is a pool party. And I was looking, I was like, do I have a waterproof foundation that I would want to wear? But honestly, for me, this is what I would do. I prefer a stick foundation for a pool party and you don't even need to go in the pool. Like I'm thinking the sun's coming. You just want to even out your skin a little bit. First of all, make sure you put your sunscreen on. But if you just want to even your skin out, I personally for a pool party would choose a stick foundation because it's easy to wipe away if I want to get in the pool. Or even if you get in a pool, it's not the big of a deal if it comes off. You're not wiping off a mask. So I would put a little bit of a stick foundation on on the areas that I want to even which for me would be the cheeks. Kind of blend it out a little bit and that would be my pool party foundation.  This is just super easy to blend into the skin. It looks very skin light. So if you're not doing a full mask layer, it's going to be relatively a traceless on your skin. You only put it on certain areas of the skin that you need. I love this. This looks so skin like on the skin. It spreads really easily and you really have control of how much you put on. If you just put kind of a dot on your cheeks and blend it out a little bit, you're going to get a very minimal amount of coverage. So this is what I personally would wear to a pool party.  I really meant it's a mixture between two. Like I said, I love my Dior airflash for that but this liquid foundation, if I want a little bit more coverage, a little bit more thickness on my skin to really perfect it. That is the La Mer the Soft Fluid Foundation. This is incredible. If you ask me, this is almost like the Dior in liquid foundation except a little bit more thick but I love the way that this looks on my skin. It looks airbrushed. My skin looks completely flawless without it being full, full coverage. There's something about the finish on this skin that's so natural and so perfecting that I love. This is such an expensive foundation. It's so good. This makes me feel so beautiful in my skin. Like I have flawless skin. I've never had acne a day in my life. I love this foundation a lot. I would wear this every day if it wasn't so much money but it is so good you guys. Highly recommend this foundation. It is worth every penny. That was the last occasion for this foundation wardrobe tag. Really, really fun. Even if you don't have a YouTube channel, answer the prompts down below. You will have so much fun digging through your foundation drawer to figure out what's the best foundation for each category. So thank you so much, Charlotte, for coming up with these questions. If you have a YouTube channel, make sure you do this tag. And it also was really fun to kind of dig out some foundations I hadn't used in a while. Thank you guys so much for watching this video. I hope you enjoyed it. If you aren't subscribed to my channel already, I hope you take the time to do so. And I will see you guys in the next one. Bye, guys. Have a good one.


Welcome back to our YouTube channel. My name is Jolie Greenbong. I'm Mary Kearick's executive assistant and today we're going to be talking again about spousal sponsorship applications but this time we'll be focusing on chat records. So chat records are essentially a way of showing proof of contact between the couple and this is important and it's actually a requirement by IRCC according to the document checklist if you have not been living together. So just to further explain this that so if you've been living together as a couple technically according to the document checklist you do not need to provide chat records however I think it's important to note that with our office regardless of whether the couple has been living together or not we always include excerpts of chat records. If you are however submitting this application by yourself according to the checklist it says you will submit a maximum of 10 pages of chat records but again with our office we usually submit between 10 to 25 pages again depending on how long or short the relationship is or how much extra supplemental documentation we feel the couple needs to build a strong application. But like I said we like to include it with all of our applications because we really feel that it helps build a strong case for the genuineness of the relationship. So when it actually comes time to choosing the chat log this can be a little bit daunting for couples because for couples that have been together for two, three, five, ten years it's really hard to be able to go back through all your chat logs and sort of take out these pertinent excerpts that demonstrate that you're in a genuine relationship. However it is really important that even if you've been in a relationship for 10 plus years that you do not provide pages upon pages of chat logs it is really important to choose quality over quantity so quantity. So that means going back and just choosing very pertinent excerpts that really demonstrate the genuineness of your relationship. And something else that is really important when you're choosing these chat logs is to show that the couple has been speaking and communicating consistently and regularly over time. So that would mean not necessarily choosing excerpts that all fall within the same month for all 25 pages because that doesn't necessarily show that the couple has been talking for 10 plus five plus years. So it's really important that when you're choosing these chat log excerpts that you're choosing them or maybe it's spread out over a few months, a few years, so maybe for the 25 pages you would choose a few excerpts from January 2017 and maybe from October 2017 and so on until you show that the couple has been speaking consistently. Another important thing to note is that all chat logs need to be either in English or in French. So if you do not have chat logs in English or French because you and the couple communicate in Spanish or in Urdu, this is fine but you will need to have it certified translated. So I know that this may be a bit of a hassle but all of our applications, every single document that we submit to IRCC needs to be in either English or French. So like every other document in the application you will need to have it certified translated. And now when it comes time to actually looking for these chat logs you can find these on a variety of platforms. So if you've been speaking over Skype, over WhatsApp, Facebook, Facebook Messenger, Viber, you can really choose it from any platform that you've been speaking over. It's just important to show that really that the couple has been speaking consistently over a certain amount of years. So if you have any questions or concerns regarding chat logs and spouse or sponsorship applications please feel free to contact our office and we'll see you next time. Thanks for watching.


My name is Ståle Hengenag, brilliant to pronounce by the chairman that's not often in an English speaking country that you have your name pronounced correctly when you come from Norway. I'm a content designer in Telmar kompetanse and we are a small company in Norway, we have been working with Moodle since ten years ago. We are working with large organizations like the municipalities in Norway. They have a separate platform, Moodle platform, with close to half a million users right now, and we are also working in other areas. I'm going to talk to you about H5P and as you are well aware of, the H5P is a family of content types with different functionalities that increase the learning, that helps us to make interactive lessons. And a couple of these, you can actually put in more content types into this single content type. So I will show you a couple of examples with a column content type and also with a course presentation content type. And if you have time and I hope we have, I can also show you a small example of a personality quiz. That's not often, at least we, not often we used, but I think we have found a nice way to do it. So these are the three examples that I will show to you that we have made for the first one for the municipalities in Norway. They wanted a self assessment of basic digital competence. They wanted the employees in the municipalities to go through some tests and to see where are my gap in this area. And then we used the column type, the content type together with course presentation and accordion. We were also asked to make a campaign for StartCraft, which is the Norwegian energy company. One of the largest in Europe for renewable energy. This is not a course, but it's a campaign to have focus on a specific area, HSE, health, safety and environment. And then last, I also included a personality quiz if you have time to do that. So let's go live. And I want to show it to you in the actual Moodle workplace platform that we are using. So first the self assessment for basic digital competence. And what, okay, let me see, stop the presentation, yes, like this. Here we are, sorry for that. The first is the self assessment, the basic digital competence. So what we did here was to take this broad area, basic digital competence. And we divided it into different subjects. And we created course presentations, including only questions, different question types. So here we have the net search. And this is all in the column, as you see. This was the net search. Here is user login. Here is security, communication, and so on and so forth. So if we take the first one, the users would go in and answer the questions. And when they continue to do this, they end up on the summary page and they can easily see what are my score. And if this was the case for me, I'm definitely not good enough in net search. So I have to do something. So the user would typically then go through all of these course presentations or tests. And they would be directed to the recommended net courses. And the way we did this is that we made an accordion. And in my case here, maybe I did fine in user login, in the security, communication, and so on. But in net search, I'm weak. So then I go to net search, and I direct it to a course. And this course can either be an internal Moodle course, or it could be out on the internet to wherever. There is a good free, usually, course in net searching. So this was the first example. This is a column where we have combined this with course presentations, with questions, different question types, and an accordion that link to the different courses. The next is the agency campaign. And this was made for Startcraft, which is the leading company, Norwegian's own company for energy. And they had already, when they wanted to launch this campaign, this is not a course. Again, this is a campaign. It's information. They want to have focus on health, safety, and environment. And they had created a word that they would use, which you see here. This is also an Norwegian lesson, by the way. Crash course in Norwegian. This word is Raus. And this is the word for generous in English. This means generous, actually extra generous. So it's a positive word. And it gives good vibes. So this is introduction. And as you can see here also, we have removed the navigation bar. So this is the active surface mode. So we direct them to where they should go, using this blue arrow. So here we explain what are the meaning of these characters. R is risk conscious. A is ansvarlig in Norwegian, responsible in English. U, we don't know yet. S is synlig in Norwegian, visible in English. So risk conscious, responsible, visible. They are all factors related to health, safety, and environment. And the reason for doing this is that this company, they would like focus on the U. And what is U? And what does this has to do with HSE? So we proceed. And here we are introduced to the letters. And we want to explain. We want to read the users to connect these words to HSE. So now we are starting to involve the learners, right? So if we click on the R, we get exported text area, which is a functionality in the course presentation. And they can write whatever they think is connected to this word in an HSE perspective. So when they do this, they engage themselves. What do you mean by risk conscious when it comes to health, safety, and environment? Then they go back. And if they now are very curious, they click on the U, but nothing happens. And if they click on the I for information, they are told to wait. You are not supposed to know this right now. This is something that is coming. So when they continue with the A and the S, they write what they think is connected to visible in this regard, we introduce them to the company, sort of company policy for what do they mean risk conscious with responsible and with visible. So they turn this, these are dialogue cards, also a part of course presentation. And they turn this, and they read, this is the company's thinking of these different words. The next is that they are introduced to two avatars or to fictious employees in this company. And the first name is let's do it and the other is think first. And this is everyone that's worked with HSE understands that this is really one of the main thing. Just don't do it, but think first. What are we supposed to do? What are the risks involved here? How can we plan to do this in a safe way? So we introduce these two avatars and then we introduce cases. Okay, let's take this into practice. What is working in heights? What are the risks? What are the safety issues when working in heights? How can we minimize the risk for accidents? And then the user should, in these exportable text areas, they should again say, how would a person that is just going to do the work, how would he think? How would a think first person think? So they involve themselves in the process. Case two, higher of external workers, what do they have to think about? Number three, ground faults. So here they should involve themselves in the teaching process or learning process. And now we come to the you. So what is you in this context? What does the you stands for? And then we found four words which starts with a you in Norwegian. This is wondering. This is unusual. This is incredible. And this is impossible. So then they have to decide, what do you think the you means? And of course probably they choose wondering, which is right. And then we go further to learn what wondering is all about. And then they are asked to do this in their own department. How can we be risk conscious? How can we be responsible? How can we be wondering? How can we be visible in our department? What do you have to do? And then we conclude this campaign with five, no six different employees, real employees in this company. And they explain what they think is wondering in this sense. So this was a way to engage the learners. We take a quick look at the last one too. I can see the time is running out. We do this also. This is for skogskolen, which is a school for forest owners. They have a platform for forest owners. And they wanted to have a course. And part of this course was for them, the owner of the forest, to find out why do we own the forest. What do we want to do with our forest? Is it for income? Is it for biodiversity and environment? Is it for use in recreational perspective? And then we created personality quiz. And when we start this, we divided this into these areas. So we asked the question, what is most important for you? Is it that the forest should be taken good care of? Is it producer of timber? Or is public access to the forest? And dependent on what you click here then, what is most important for you? Now I take the biological diversity and environmental perspective. And I click on these. And then you end up with, you are a forest owner with focus on environment and diversity. If you have chosen all that was related to income, then they would find, oh, you are most focused on income. So instead of asking just questions, what do you think is most important, then this is better, because they get involved in this way of thinking. And we get the better result. So this was three examples of what you can do using H5P to engage your learners and to motivate them to take these courses. Thank you. Thank you very much. Awesome. We'll have the next presenters begin to set up. I will allow a question. Thank you. I think you showed it at the first slide, but could you tell us what you used? Obviously you used course presentation for the second one. But what are the two other features you used, the first one and the third one? Yeah. The column was with course presentation and the accordion, right? Which one, the first? The column, yeah. Okay, yeah. It was a column. And then it was accordion. And then it was accordion in the column. The one where you were just asking questions. Okay. And the third one? The third one was personality quiz. Personality quiz. I agree. Thank you. And the second one was course presentation in active surface mode, right?


Welcome to BCH Technologies. This is Kevin. Today we're going to change our printhead for T-79, which is... And the first thing you do, of course, is to shut off the electricity when this car is moving.  Some people just yank it and took it out, but if you do that, you're going to leave a piece in there.   And you might get some help from the screwdriver too. Okay, so you put this piece out and the cover will come right off. This is important because later on you're going to move this piece. So some people still have this thing in it. They just rip this off with this piece in it. If you do that, then later on you'll need to remove this piece so this can be pulled out. Okay, the second step is to remove this board. I have one that is already removed. So it goes down like this. What you can see is you get a tab here and you get a tab here. And you don't need to figure out where's the tab. So because this thing is slide on a wall and you can see here this is the notch that holding the tab.  So slide in, just push the screwdriver towards the wall and just squeeze. And you'll use your thumb to lift this thing up. So this side is up, then we work on the other side. So once this whole thing is freed, don't forget to put some gloves on. If the whole thing is freed, we need to remove this piece of plastic. And just remind you again, if you still have this guy in there. If you have this guy in there, you can use your pliers to bend this, but it's likely it's going to break. Or just like me, you just pull the whole thing out. And let's see, one tab is here and one tab is here. And remember the ribbon, see there's a curve here. All the ribbons are sitting like this. So just remember this when you put it back. And now we can disconnect this. Remember for this one, the blue part is facing towards you. Now we're going to remove these screws. It's better to have a magnet, magnified screwdriver. So one's here, one's here.  And they give these labels. So this one is on the, so what I do is I always make the label that's towards back. And this is the chip. And we got a printhead out. So I'll say this is the printhead, printhead. And this is the bottom. That one is not the screw hole. I often get confused. It's the one here on the bottom. Now the chipboard. And often this chipboard, this assembly is really loose. So there are lots of time you put it in and this gets knocked off. And then when you turn a printer on, the printer just says there's no cartridge. If you turn the printer on and say there's no cartridge and you want to test whether it's this cable is loose or you have something going on with your chipboard. What you do is you can take your CIS out and put the original Epson cartridge in. You don't need to put all of them. You can just put one or two of them. See if the printer can recognize it. If they are, so you don't have to take the printhead out again. Focus on troubleshooting the CIS chip. And another time is I did think if I always pull and then they got disconnected and you might get a problem. So remember what we said earlier and you need to put those things in here. I know how I got disconnected. So when you put this thing in, you probably just pull on this. So get a disconnect. Just to make sure it's still good. Yeah, I still good. So now I got this piece and now we put the CIS in it. I hope you enjoyed this video. Visit us at www.bchtechnologies.com or locally at Greensboro, North Carolina. Thank you. Cheers.


Hello, everyone, I'm Sanjay Gupta. I welcome you on Sanjay Gupta Tech School. In this video, I'm going to discuss about HTML templates data binding and I'm going to demo you how you can fetch data using query selector. So in previous two demonstrations, I showed you data binding with the help of property and data binding with the help of data property, right? So here in this example, I will give you a small demonstration around query selector. So first time jumping to HTML file. So I'm just toggling this explorer so that we can have the full space to implement the code. So in this HTML file, I'm just going to remove this code and I'm writing a P tag which will display hello and I'm using this greeting attribute. Now after this P, I'm going to use lightning input then label will be name and value equals to greeting. So by default, this lightning input will be having a greeting as a value and this greeting is a property. So this property's value will be assigned to this value attribute and it will render on the UI. So whenever we will be rendering this lightning web component on the UI, so this lightning input will be having some pre-filled value that is available in this greeting. And in this greeting, we will be storing some value in the JavaScript file. Now after this, I'm using VR tag for line break and then I'm going to use lightning button. So in this demonstration, I'm going to use one more element that is lightning button and its label will be click me and on click of this button, we are going to call a function that is named as handle click. Then we can define the variant as well. So variant I'm defining as brand and I'm closing this lightning button element, right? So in this lightning input, we have used a property in this lightning button, we have used this function which will work on on click event, right? In previous demonstration, if you have seen that video, so in that demonstration, I used on change event here with the lightning input and then with on change, I was calling a particular handle click handle change function. So this way, like if you want to have a function associated with lightning button, so this way you can do. So HTML file is implemented, but it is showing two errors because this greeting and handle click we need to define. So I'm jumping to JavaScript file and I'm just removing this code which I implemented in the previous demonstration. So here I'm going to create a property named as greeting and here I am storing my name. Then I'm going to define a function that is handle click and it will receive a parameter event that we used in previous demonstration as well. So whenever I will be clicking on the button, so this handle click function will be executed because here we have just called handle click function with on click event, right? So now if I save this file, come here, still it is showing the error. So let me just finish the implementation. So now through this event, we will be fetching the value and we will be storing it into greeting property. So this greeting property we are using, reusing here. So that is why I'm using this dot greeting, then equals to, now this is important. This dot template dot and then you need to write query selector. So query selector is a function and here you need to define like which element you want to be selected. So I'm just using lightning hyphen input and then dot value, right? So what will happen? So this dot template dot query selector. So this dot template means this components template. So this components template is available here. Inside this template, wherever you have the query selector like lightning input. So we defined query selector as lightning input. So this lightning input will be selected and its value, whatever is the value, like after changing whatever value is available there. So that value will be fetched and it will be stored in this greeting property. And that greeting property we are displaying here with hello. So once you click on the button, so that handle click function will be executed. It will be assigning the modified value into greeting attribute and that, sorry, greeting property and that greeting property is reactive. So it will show the updated value on the URL. So this way this JavaScript file is implemented. So I'm just saving it. And here we are on HTML. I just saved it as well. So still it is showing some error. So now if you see some problems here. So what you can do, you can just go to this problems tab and you can try to read the error. So it is saying ambiguous attribute value, value equals to greeting. If you want to make it a valid identifier, you should remove the surrounding quotes. Okay. So what I did by mistake, I just used double quotes. So we have to remove this here and from here as well. So double quotes are not required. You can just write them directly, right? So whenever you write value equals to, so sometimes double quotes are available. So you can just remove and then use it like this. So now both HTML and JavaScript files are saved. And this dot XML is already having target as lightning homepage. So now I'm going to deploy this component from source to org. So that whatever changes I have done, that will be deployed. Now I'm going to refresh the homepage so that updated component will be rendered on the UI. So here you can see we have hello, then Sanjay. By default it is showing Sanjay because in greeting property I assigned value as Sanjay. Then name is the label of this lightning input and it is having by default value as Sanjay, right? Now if I remove this and write the cast here and now I need to click on this button. So as I click on this button, so this value will be fast and it will be stored into a greeting property in our JavaScript file. And here after hello, you will see this name. So if I click on click me, you will see the change here. So this way, whatever value you provide in this lightning input, if you click on this button so that value will be fast and it will be stored in greeting property and greeting is reactive. So every time whenever you change something in the property so that that will be reflecting immediately on the UI. So this way, I hope you understood like how we can fast the value with the help of query selector. So through this query selector, I just used lightning input and then dot value. So whatever value was available in that lightning input so it was stored in greeting property and then it was rendering on the UI. So this way, like this was the third way of data binding. So initially like I showed you data binding with the help of property, then I showed you data binding with the help of getters. Now in this video, I just explained to you like how you can bind the data with the help of query selector, right? So this is all about fax data using query selector so that you can implement the data binding in lightning web component.


Today, we are going to discuss the seven emergent trends in early childhood education, so the world over people are thinking and rethinking about how we can train, how we can teach our early children. So, one of them is the increased recognition of the importance of early childhood education. The importance of early childhood education is not felt so much before. It was understood about the children that when they grow up, they will learn. Right now, they don't keep anything so important for them or maybe they are not learning. So, now that people have come to know that the whole life's impact is on the early education and early education of the children. After that, a lot of theories are also coming forward and a lot of things are being done on it. And a lot of things are being emphasized on them more than before. Then one thing is that our assessment process is also being revisited. Earlier, as we are saying that there was a test, a standardized test, through which children were checked, assessed. There is a school test or a teacher test. And through those tests, anxiety arises in the children. They cannot perform at that time. For example, the child is tired, he is in no mood, he has no other problems. And you all understand that a very small child whose attention span is so low, how can he think and write on the whole child? So, it is not possible for such a small child to be given such a hard assessment in the beginning. So, everyone has thought that there should be something different for the children's assessment. Then there is a pattern of the growth of the children and it is with time throughout. In the beginning, the growth rate is very high. And in the coming days, in fact, it goes down. As it gets bigger, the growth rate of its intoxication is already decreasing. Then we see that because of this, physical fitness is very strong on it. Look, you can give strength to academics, you can increase their syllabus, you can do their curriculum better. But you cannot ignore their physical fitness. Because if the child is not healthy, his muscle-brain coordination is not possible, he cannot walk, he cannot play. So, in this situation, nothing is possible. So, the outdoor activities of the children, the physical fitness in which they run and play, all these things are included, they are being given more attention than before. And according to the school, they are being included in their curriculum. Then look at the new century, the 21st century, there is a storm of technology, a revolution has come. So, obviously, there is a lot of distraction for the children. So, now that all the people are concerned about this, we should think about how we can get the children to understand the better technology. And what kind of technology they have, so that they can benefit from it and save themselves from its loss. Then, increased demand for teachers to have more qualifications. Look, if we want to do all these things better, we want to revisit them, if we want to do better than what was happening before, then the education of Asadza is also as important. So, it is said that Asadza should be better qualified. When there was a time, there were some decades, in Pakistan, for the first 40-50 years, there was no such condition, that for the early education or the ECC education, Asadza should be given training or education. But now, it is not like that. Now, for this, there are many cadders, there are programs for the honors, and there are programs for the masters, where early childhood is specially taught. Now, look at the changing demographics. There was a time, when people were not that much of a class distinction. Now, the class distinction is increasing. The world is becoming global. And people have already had many political issues, that the difference between the rich and the poor is increasing. The remote areas were not at all easy. And where there were hubs and cities, there were a lot of difficulties. So, that digital divide also became one. There is a difference on the basis of technology, there is a difference on the basis of money, and then there is a difference on the basis of culture. So, we are saying that, we are looking at all these demographics, all these socio-economic backgrounds, paying attention to the children, and paying attention to their education according to their context. And for that, use the appropriate teaching approaches. Thank you.


Welcome back. Let us consider illustrations of some real life system. Here you have a photograph of a power plant. There are a number of units in this station but in the forefront you will see one thermal power plant. It takes in coal, produces electricity. It takes in cooling water, slightly warmer water is thrown away and through the stacks you throw away flue gases, the burnt product, carbon dioxide, end of the stack. We may consider the whole power plant as our system. It will be an open system because it takes in coal, throws out through the chimneys and exhausts. Because it is coal, it may contain some ash which does not get burnt, so ash is also discharged. Then you have cooling water going in and cooling water going out. And then of course you have energy output as electricity. This whole thing can be considered to be a power plant and we can apply our principles of thermodynamics to such a large system. However, it is also possible to consider components of the power plants. For example, the main subsystems in the power plant are the boiler sometimes called the steam generator. Then steam goes to a turbine. From turbine low pressure steam goes to a condenser where cooling water comes in. So this is the cooling water circuit. Steam condenses, the condensate is pumped back into the boiler. This is a very simplified form of our power plant. Now the turbine produces mechanical power which is passed on to the generator. The generator creates electricity which is the output, final output of the plant. Apart from this, you have in the boiler a furnace in which we put in coal. Air also goes in. It is required for combustion. Ash discharged at the bottom and flue gases at the top. Now this is the approximate internal detail of the earlier system which we saw. So I can put a dotted line around all this and that is essentially the system we saw few minutes ago. But it is also possible to consider subsystems. For example, this is my turbine system and I can apply my laws of thermodynamics to this smaller system which consists of the turbine. One inlet, one exit, so it is an open system. Similarly, we can apply the laws of thermodynamics to the condenser as a system or to the pump as a system. When it comes to boiler, we can consider just the water holding and water flowing part of the boiler which converts water into steam as our system or you could have the furnace which handles coal, burns it with oxygen from the air and transfer the energy liberated as heat to the water in the boiler. That could be a system. This is just to illustrate that the choice of a system and its boundaries is our choice. If we want to look at something at a gross level, overall level, we can consider the whole plant as a system. If you want to consider subcomponents, study their characteristic. For example, we can have the turbine as a system. To study the details of the turbine, we can even go to the internals of the turbine and there are various stages. A typical turbine will have anywhere between 10 and 20 stages, stacked like slices of a loaf of bread. Each stage can be considered as a smaller thermodynamic system. And if you really want to go into details, a stage consists of a few dozen to a few hundred blades and the space between two blades can also be considered to be a properly defined thermodynamic system. So the definition of a system depends on what we want to study and in what detail. Now here we see a photograph of our earth taken from space. Can we consider the whole of our earth as a system? And the answer is yes. All that we have to do is set up an appropriate boundary. We set up the boundary and we say this is earth and its immediate surrounding that is the atmosphere as our system. What would be the neighboring system across the boundary? That would be the part of space part of the solar system just across our atmosphere. We can apply and we do apply the laws of thermodynamics to our earth as a system.  Finally we ourselves each one of us is a thermodynamic system of the biological kind. Of course we any one of us as a thermodynamic system can be studied thermodynamically. However the structure and the internal working of such a system is so complex that in this course we will not make an attempt to study that. Thank you.
