Subunit 3.3, phase A. So let's talk a little bit about what happens during phase A. At this point, you've got some kind of baseline system requirements that you're developing. And in phase A, you're going to really try to work on taking those high-level objectives that the stakeholders define and trying to make these requirements from them. And so we'll talk a lot more about requirements in the other units. What you're trying to do here is take these objectives and break them down into lower and lower levels of detail so that in the end you could provide specific information for, let's say, the person who's going to go off and buy the propulsion tank or the person who's going to go off and buy the battery for the spacecraft. They need very specific direction. The direction is going to be documented in requirements on what the specifications are for that battery. How much energy does it need to hold? How much energy does it need to be able to send out to the spacecraft during the time when the spacecraft is going through its eclipse period where it needs to have the battery providing energy to all the systems? And so all of those requirements at the very low level need to come from all the way back to these objectives that the stakeholders have defined for how this mission needs to successfully operate and what it needs to be able to do, science collection or whatever the objectives are for that mission. So what you're doing here is at the phase A level, you're making sure that the high level objectives are starting to be decomposed into lower levels of requirements, we're now calling them requirements, lower levels of requirements that will allow the system developers to provide more specificity and more detail to all the components of the spacecraft on what they need to do to meet the high level objectives. So specific activities in phase A include developing top level requirements and top level. So we're going to use that term to refer to the first level of requirements that are under the system objectives, under being as in more defined. So stakeholder objectives are at the higher level. They say, let's say for a Mars mission, objectives might include looking for water on Mars, objectives might include studying the atmosphere of Mars to understand its composition. So that's the kind of stakeholder objectives that we might have for a NASA mission. So now the engineering staff has to say, well, gee, what kind of requirements would I have to levy on the system to be able to look for water or to analyze the atmosphere? And so again, we'll get into more detail, but now you're going to get into lower and lower and lower levels of specificity on how the system needs to work to be able to accomplish those high level objectives. And so top level will be the first level of requirements that you define. And now you're going to go lower and lower. And so we're going to call the next, you see in the next bullet, you've got to flow these top level requirements down a few more levels of detail in phase A. And we're going to call those a high level set of requirements. And so you're going to flow them down maybe two more levels of detail and you're going to provide more specificity along the way, right? And you're going to try to figure out what are your driving system requirements? What are the requirements that are going to really cause your designers to have to stretch to meet them, right? What are the requirements that are going to really cause maybe a new technology to have to be used or some, you know, new technique on how you design a satellite? So you want to understand for your specific system, what are your driving requirements that are going to really be the key ones for making sure that the objectives can be met and that are the ones that are going to really push the designers to, you know, to make sure this design is compatible with these objectives. You're going to also define all your primary internal and external system interfaces at this point. Remember, as you decompose any problem into smaller and smaller pieces, there become many more pieces. They all have to interface with each other. And so both within the satellite itself, the power system needs to connect to the propulsion system or to the computer system. Everything needs to connect together. So you need to have to find those interfaces because in the end, there'll be many teams off working on their individual part of the spacecraft. And when they're doing that, you want to make sure that they understand exactly what the interface will be between them and all the other parts so that when everything comes together, everything can work properly to meet those high-level objectives. You also want to understand external interfaces because the satellite doesn't live by itself in its own world as a system. It has to interface to a rocket at launch, a launch vehicle. It's going to have to have certain capabilities to interface to the launch vehicle. When it's on orbit, it's going to have to communicate back to an antenna on Earth and has to be able to interface to that antenna, which is usually used by many missions. So it's an antenna that's already there. It's its own system. So you have to have an interface to that system. So all those kind of high-level system interfaces need to be defined here in phase A. You're also going to perform some key trade studies to evaluate design attributes and alternate design attributes. And we'll talk more about trade studies in another unit. But trade studies being you're going to trade off some alternative ideas. So maybe in the world of propulsion, there are two or three different types of propulsion systems that might be able to meet most of the requirements, high-level requirements for your system. And you might look at them and say, well, gee, which one do I think is maybe the best one? So I'm going to trade them against each other. Which one costs the most? Which one can perform the best in meeting my high-level requirements? Which one uses the most power, electrical power? So I'm going to be doing these studies to look at all these kind of high-level what kind of decisions do I want to make. And you'll be continuing to do trade studies throughout the lifecycle. But in phase A, you're kind of initiating that process to try to refine your system. You're also going to establish an initial system baseline. You're going to identify any key technologies that will require investment during phase A and B to make sure they're ready to be used in the system implementation. You're going to refine your lifecycle cost estimates to make sure your stakeholders understand how much it's going to cost to your best estimate of how much it's going to cost to complete the entire lifecycle and get through the development of the system. And you're going to put in place all of your management tools here in phase A to make sure that along the way, through the rest of the lifecycle, you've got a clear way, clear set of processes and tools to manage all your resources. And resources could be anything from money and schedule. Those are resources and development, as well as things like power and mass, where you only have a certain amount of them to give away to all your development team. And so you have to manage those resources, well, those technical resources. You're going to have to have management processes in place to manage all the risks or things that concern the team that have to be dealt with throughout the lifecycle, as well as all your system engineering processes to make sure that the team gels as a team and understands roles and responsibilities between team members and kind of how you're going to work through the process in a system engineering sense as well. You'll see the example here of the Morris 2020 rover. And so this is a rover that's currently in phase A being designed by the Jet Propulsion Lab out in California. And so this is what you see in this picture is, although a concept, an early concept, again, they're not building it yet, phase A is really the early part of the development cycle. But now in this part of the cycle, they're trying to neck down to one concept. So instead of in the previous example where we had many, many different concepts that could meet the objectives, they're using now one baseline concept in phase A to try to flush out a little bit more details. Maybe there are more than one concept, sometimes there are, but you are trying to move towards a single design as opposed to many different concepts that can meet requirements. So for Morris 2020 rover, it was easy to move to phase A because there are some high-level requirements. They want to keep the budget within, it sounds like a lot, but $1.5 billion. And at $1.5 billion, the only way to do a rover on Mars that's the size of an SUV is to reuse a lot of technology and equipment from the past. And so in this example, you're looking at a rover that will be basically designed around the Curiosity spare parts and the Curiosity technologies. The scientific instruments on board will be modified, changed, and there will be different instruments on board, but the basic shape and the whole system that's going to be used to land it on the surface and rover around will use a lot of heritage from the Curiosity rover. And so that's how they're going to try to keep the cost down, but that also means that in phase A, there are less trade studies to do, there are less analysis to do, because a lot of this is a given. You know what this rover is going to look like. So in phase A, that's the kind of studies you're doing is to try to bring it down to one concept, trying to mature it a little bit and see where there might be some flaws in its ability to meet the objectives, so that's the kind of maturity. So the primary technical reviews in phase A include both a system requirements review and a mission design review. So the system requirements review is where you're going to bring the external technical team in again, and they're going to look at things like have your top-level requirements been clearly defined and do they fit in with your high-level stakeholder-defined system objectives? And so the goal here is you're looking at, you know, did I do the flow down correctly if I looked at these top-level requirements, yeah, do they seem like they're the right ones to meet these system objectives? And then the next bullet is, you know, if I define the top-level requirements right, did I take that down to the next couple levels of detail and form a good set of high-level requirements that look complete to be able to again meet the high-level system objectives? Now the team will also be looking to see if all the internal and external system interfaces have been clearly defined. And that all the risks for the development of this system have been clearly identified and there's a plan for addressing those risks. And that things like a system engineering management plan, how am I going to manage this project from a system engineering standpoint and all of your other processes and tools for management have all been put in place and are ready to go. And that there's an initial plan for verifying and validating the system and we'll talk more about verification and validation in another unit but suffice it to say that as you're defining requirements for a system, sooner or later when you build the system, you're going to want to verify that that system as built can meet the requirements and a requirement might be a performance capability. A thruster needs to be able to provide a certain amount of thrust. Early on when you're developing requirements you may have defined how much thrust later on when you actually purchase a thruster and you might say well gee, let me test it on the ground make sure it can produce the amount of thrust that's required and you might also say well gee the thruster can only weigh a certain amount because overall the whole system can only weigh a certain amount so the thruster has been given an allocation of that and the thruster itself can only have a certain amount of mass so you might put it on a scale and say well how much is that thruster and verify that the requirement I set for how heavy it could be can be met by the thruster that I actually went ahead and purchased and so this plans for verifying and validating and validating here is another term that we'll talk more about and validating is making sure that as you put the system together it performs as a system and meets those high level objectives that you set out for it so verification being very specifically requirement by requirement should, validation being when I put it all together does it perform and meet the high level objectives that were set out for it by the stakeholders and so those plans are developed early on you know you think about that when you are starting to define requirements and objectives you also have to start to think about how in the end when I actually build this thing later on at the end of the life cycle how will I make sure that it's going to perform the way I want it to will I do that through testing in a computer how will I actually do that verification I have to think that through now because I might need to build special tools to be able to do that verification special equipment so I need to know that so that I can make those investments throughout the life cycle I'm also going to look and see that the plans for technology development have matured and then I understand all the technologies that need to be developed and completed before the end of phase B and the system requirements review will also look at the results of any actions that have been assigned to the team back at the mission concept review and so the goal here is that at each one of these technical reviews the technical review team is going to assign some actions to the designers and say you know we thought your system is pretty mature we think you're ready to go to the next level but you know there are some areas of concern we don't think you've thought enough about X Y or Z and we want the team to go back and do a little bit more work on that improve to us that you've completed that so at the next review you're going to want to make sure that all the actions have been closed out the second technical review that happens during phase A is the mission design review so during the mission design review this is again after the system requirements review on the life cycle and at this point the technical review team will be back and they will now be assessing things like your baseline concept baseline concept being your current design instead of requirements and all the things that define the system at this very early part of the life cycle everything you've put together to define what the system is and how it will operate and they're going to look at that baseline concept to ensure that it's reasonable, feasible it's complete it's responsive to the high level requirements that you set out for it and it's consistent with the available resources resources being anything from technical resources like mass and power to programmatic resources like cost and schedule so they want to know that as you're maturing this baseline concept and adding more detail to it that it still looks like it can be executed and that it will meet the high level objectives and be able to be done within the programmatic resources available so they'll also be looking to see that your system level design approach and your operational concept are maturing so that they are consistent with the high level requirements so there's two things going on you're developing requirements what will the system need to do how will it need to perform that's what's being defined by requirements but you're also starting to work more and more on this concept kind of an early stage of a design what is this system going to look like and so you're going to look at in this review both the requirements make sure that they're maturing properly but that was done mainly in the system so you get this design that you're starting to come together with to make sure that it's maturing and could meet the requirements that are being laid out for it you're also looking at any risks that have been identified along the way that the team is worried about things that again may preclude us as a team from being able to finish the system development on time on schedule and meeting its technical objectives and so the review team is going to want to know that you clearly understand the risks and by understanding risks you also have a plan for how you're going to deal with those risks what kind of mitigation strategy or what kind of steps are you going to take to make sure that that risk doesn't end up causing you problems in the life cycle you're also going to be looking at the technology maturation effort you're a little deeper into phase A at this point so the review team wants to know is everything on track is your technology plan executing as planned and are you ready to go so that by the end of phase B you can be matured to where they can be ready for flight and ready for implementation and then you're also going to look back at the system requirements review and say okay were there any actions assigned by the technical review team back at system requirements review that needed to be closed out and what's the status of all those actions you want to know that they've all been completed there are no additional resources for this subunit feel

We're gonna set it for 30 minutes. What will her using, the ink? Since she wants it pearly, we're just doing a couple splashes of this the opaque titanium breast and sparkly shimmer. So you know how on that one, like those little square samples I did, I just like moved around the nickel in it. Just feel like you don't have to vane it, just put it in there and just move it around with your hands unless you wanna vane it. But I feel like the veins are gonna be light. So I didn't do that much of it.   It's just supposed to give it like that clean base that she was talking about wanting on her. You like that a little bit better? So do you wanna do gold, rose? Do the gold mix then. All right, so this is just a hint, right? We're not putting a lot. Use the roller at all with this one. You're just asking, not saying you should, I'm just asking. No. I love these little bubbles. I think that it got in there, right? That's what you said you wanted to do? Yeah, you just do some, what, when this is done, is to pour that out and then do, so that's the one we got from your mom's. I know, but it's the same, like the bottom one's the same. I like that you can see the white. Mm-hmm. All right, so we wanna put it, let's put the next thing that goes on. There should be a crossover between one and the other. I'm gonna put a little white down here and then blow on it. That's just a little bit too blue. On the top of that one? Yeah. That's just not enough for me. Well, this is what I like about that, using the Gola, because it huddles, like it, you know, gathers, like, you can see it, the metallic. It's like, there's so much dirt, there's so much dirt. I don't, okay. It's kind of blue. Very subtle, blue is like not overpowering. I almost wanna do that more of that cream, so it did, like, the first of it, so then the white marbles out. Yeah. You wanna come back in, like, two hours and put a clear coat over it. Two hours is getting myself a little done. You think? Two hours? Three hours? There's some of those little ones down here, coming off here and here. I almost like it when it says that one.


Organizers of the International Eelpalt Festival have made their first public comments regarding a possible change of venue for their annual event. Lakeland News first broke that story for you on our website last Friday afternoon and then later reported on it on our 10 p.m. newscast that night. Eelpalt officials have submitted an application to Beltrami County for approval of a permit to hold the festival on Lake Bemidji in 2018. The festival has been held in Walker since 1979. The Beltrami County Planning Commission will present the application to the county board tomorrow. Today, Eelpalt officials posted a statement on their Facebook site saying they are exploring any and all options to ensure a feasible future for the festival. The statement goes on to say Eelpalt organizers have been in discussions with Walker officials as well as community leaders in other potential locations and that no final decisions have been made. Officials also say the festival will take place in February somewhere, but the exact dates cannot be confirmed at this time. The statement says further details will be announced in the weeks to come.

There is one tool in TubeBuddy that once I started using it actually paid for my TubeBuddy subscription for me And that's what I'm going to be talking about in this video And I'm going to be sharing with you how I used it so that you can understand how you might want to do the same And it can maybe help you out generating a little bit more revenue for Your channel and whatever you're doing around your channel So let's get straight on into it shall we and I'll break the suspense. The tool is drumroll, please It is the find and replace tool I know it doesn't really sound too glamorous does it but it really has helped me a lot So let's look at what we can do with it and that's specifically what I did with it to generate some extra revenue for the channel So first of all, let me show you where to find this We're in the YouTube studio in our content section and here up at the top We've got the bulk and miscellaneous tools and the first one on the list actually in here is bulk video Processing and we've got find and replace text. We've also got thumbnail overlays Which we'll be talking about a little bit later as well, but we're going to start here with the find and replace text So how is it that this managed to pay for my TubeBuddy subscription for me? Well For the first hundred and fifty videos that I did on YouTube, I would guess it was around there I don't remember exactly the number, but it was something like that my my descriptions I didn't really put a huge amount of thought into them I put thought into what I was putting into my main description for the actual video But I certainly wasn't filling them up with the potential of five thousand maximum characters that you can have in there What you'll notice in my descriptions now if I open any one of these particular videos We've got the sort of main video description up here and something related to it And but this bit down at the bottom is actually text with things like, you know my my store take one tech I o slash store for place for people to put consultation calls with me take one tech I o slash consultation it makes sense really to have all of these links down here so that you know if anyone's watching and Wants to get in touch wants to you know have a chat about anything then there are ways for people to do that I also realized that people were interested in the sort of gear that I was using as well And so I do have a link down here for you know different gear that I'm using And what the point about this was I wasn't having this in the description when I first started my channel And at some point I saw somebody else doing this so I just basically thought that's a great idea I'll have to start doing that going forward, but as I say I had got 150 or some odd videos that were that were already up there So what I wanted to do was add in all of that extra information and also all of those affiliate links into all of my My video descriptions for those that existing content So that is where the Find and replace comes in it's really simple to use it can do more than this as well Actually, which I'll come to in a little while but it can do more than this But we can just click on to find and replace and it can be as simple as Find text so all I did was I did look for the sort of stock Template I was using rather for my descriptions and there was a bit of text in there It just wasn't as complete as it is now So I just did a simple search for that particular piece of text and then I added in the replacement text And by the way, this box looks a couple of lines deep But you can just add in you know up to the 5,000 characters if you wanted although that wouldn't leave much space for anything Would it and so I did a replace with all of the the links all of the you know The little emojis and stuff like that that I'd got in there as well wrote that all out and then just pasted it into here the replace text Then you can do things with search So for example look for things that are case sensitive so you can include that you can include Partial word matches as opposed to complete matches and then you can also search in titles or descriptions So I am talking now about an example where I did it in just the descriptions However, this is also a great way if you want to go and update titles You can just do it exactly the same way as well And then once you click on continue all it's going to do is just bring out all of the different matches It will tell you the videos where there is a match and then you just click on Basically go and it then takes the time to go away and add in all of these different Replacement text into all of your descriptions or into your titles and it takes a little while I'm talking like a few minutes or something like that But it's certainly a few minutes that you're not spending and it's also at saving you You know a lot more time than a few minutes because to actually go into every single video and replace all of that text would certainly be a Lot harder and longer job to actually do that So that was the first thing that I did with this particular tool and I added in all of my Amazon links Now what I actually got out of that was I got a tenfold increase on Click-throughs to my Amazon affiliate links because I Previously I did have a gear page on my website where I listed all the gear that I use and I'd have my Amazon affiliate links for all of those Different items that I use and recommend And then if I was doing a video about a specific piece of you know gear my mic or something like that I would have a link to it in the description then But I didn't have this sort of almost, you know a complete high-level gear list down in the description itself So I did get a tenfold increase in traffic through to my my Amazon Affiliate links and then from that that generated revenue, which has actually covered the cost of the the actual TubeBuddy Subscription now I should say that this is not something that's available on the pro plan, which is the lower plan It's on star or legend But yeah, it's certainly if you look at the cost of the star and the legend plan It's certainly if you're you know generating traffic and I've got views on your Your page then it may be something that you might want to to consider there I'll just mention again If you're not use using TubeBuddy Take one tech.io slash TubeBuddy Link in the description for this as well. That is my my affiliate link And that's one of the best ways to help out the channel is to is to use the affiliate links down below If it is something that you're interested in checking out for yourself And so that is a basic find-and-replace just finding a piece of text and then adding in some some text in its place We've also got some other options in here though. So we can either Insert after text or insert before text and you've also got remove or delete text So if there is a say for example, you've got a particular link or something in your description that you want to just completely Remove it's you know a dead link or something like that. You can just go and delete that and Add text to end of description or insert text at beginning of description or replace entire description So there's different things you can do there But this one in particular insert text at beginning of description This is one that I've used recently when I launched my e-cam live masterclass e-cam live masterclass.com To tell you everything from beginner through to experts of using e-cam live And linked to that is in the description When I launched that I wanted to because I've got over 80 videos In fact probably over 90 now on my site related to e-cam live I wanted to basically go through so that anyone who's coming back and watching those videos You know after I launched the masterclass I could leave a link to it So I actually went through and use this sort of prepend option to insert text at the beginning of the description So now at the beginning of all of my e-cam live videos I've got a little bit of text that says you know if you want to learn more about e-cam live in a structured manner Then check out the e-cam live masterclass lifetime access for just $149 and includes over $150 worth of bonuses too So I added in some words to that effect and so I added that into all of my e-cam live videos So it saved me a whole bunch of time in you know I certainly wouldn't have necessarily had the time to go back or wouldn't made the time Realistically to go back and physically add that in you know going into a video editing it pasting in the text coming out Going into the next one and so on it would have taken quite a long time and For sure that has driven people to the e-cam live masterclass and has driven sales So it's definitely been worthwhile from that perspective So really although this is quite a you know simple function really find and replace It's not particularly complex at the end of the day. Is it from a you know a Just written on paper. However, it has been quite powerful for me in terms of generating revenue from it for the channel And also just as I say saving me a bunch of time, which is what TubeBuddy does really well if you value your time Then yet TubeBuddy is definitely something worthwhile now mentioned the thumbnail overlays So with thumbnail overlays you can actually add a you know an image or a partial image over the top of your existing Thumbnails that you've got on your site on your sorry on your your YouTube channel I should say and so I'm going to be talking about that tool in the next video so that you can learn how to use it and Also discover what it can do for you


Welcome back to my channel. So today I've got an energizing cleaning video for you This is for those days whenever you just don't feel like getting up and getting it done This is my normal like I would say daily pickup routine. It doesn't always happen in the evenings Sometimes it happens in the afternoon whenever my daughters are taking their naps, but this night I just had enough of the mess and it was time to pick up I didn't even plan on filming to be honest with you But I just needed the motivation myself. So I was like, you know what? I'm gonna get up and film a cleaning video and I decided to pick out some energizing music to put to this So that it gets you up and gets you going Time I film a cleaning video at night I always get a lot of comments about the fact that we don't have any shades or curtains on some of our windows And that is because they are facing a direction where nobody could see in that window And I absolutely love daylight and just natural light So I would rather not put curtains on windows where that can all come in without people seeing from the outside Let me know in the comments when your prime time is to clean Is it in the morning the afternoon late at night like this? This is kind of an odd time for me generally I do a lot of my cleaning in the morning. It's whenever I'm the most energized to do it but this day I just didn't want to wake up to it the next morning and I knew I had a lot more to tackle the next morning than cleaning up just the things from the day before This day I had also been baking bread so you'll see that my mixer was out I had ingredients left out on the counter that always adds an extra level of mess Do you guys find yourself doing a lot more baking these days? Especially since we've spent a lot more time at home in the last few months It's definitely inspired me to do new things and try new things This is the book that I'm listening to this night. It's called unexpected by Christine Kane. It's so good It just talks about having The courage to walk through unexpected situations because we all have those in life. I love listening to audiobooks it's really what I do a lot whenever I clean and I actually recently got these headphones that I'm wearing right now. They are a cordless headphone They look a little bit like AirPods, but they're a much much cheaper version from Amazon and they work really well I'll try to remember to leave them linked below If you guys are looking for a pair that are handy whenever you're cleaning and doing things around the house I grab my Norwex dish soap for the dishwasher and put that in there I'm still been using that and still been really loving that I also use the rinse age that goes along with it and those paired together I haven't had any issues with my dishes being You know having spots and things like that on them. So again, if you're looking for something more natural I highly recommend that and then I went ahead and hand washed The other dishes just because I had done a lot of cooking and baking this day And I had a lot left over and you know that I loved from my dishwasher even multiple times a day But this day I just had a lot of excess from baking. I got my diffuser going that always energizes me and Gets me the little bit of boost that I need to keep rolling through the house I put in some serenity, which is kind of a Relaxing chill blend since I was winding down from the day. I thought that that was appropriate. I Don't mop the floor every single day But like I said with baking and then the girls had gotten something really sticky across the floor this day I just felt like I needed to do it and that way it wasn't on my list for the next day So if music is your thing that gets you up and gets you energized to clean What is your favorite music to listen to? Maybe it's a certain song or a certain artist or just a certain type of music Let me know in the comments Like I said for me I've been in a huge kick of listening to audiobooks lately They just make it interesting and a little less boring to get my things done I hope that this video got you motivated as much as it did for me to film it And I hope that it inspired you in some way if you're new here Don't forget to hit that subscribe button give this video a like for me And I'll see you guys in my next video


Takeda's liver-tenuated dengue tetravalent vaccine candidate, TAK-003, has been shown to be immunogenic with acceptable reactogenicity in phase 1 trials and a randomized, double-blind, phase 2 study. The primary objective was to show immunologic equivalents in terms of geometric mean titers, GMT, of neutralizing antibodies to the four dengue serotypes one month after one dose of the lyophilized and liquid formulations. However, the primary endpoint was not met because immunologic equivalents after one dose was only shown for the DNV-2 serotype. Nonetheless, GMTs and seropositivity rates to all four serotypes were achieved with all formulations after two doses and are in line with what was observed in previous studies. The data support continuing further clinical development of the lyophilized TAK-003 formulation.


The Stedman Clinic and Stedman Philippon Research Institute are the proud sponsors of the Kids Adventure Race here in Vail. We're positioned here in Solaris Plaza and we are considered the spirit booth. So we have posters that kids can make to cheer on the racers throughout the weekend. Kids Adventure Race features orienteering, running, mountain biking, and obstacle courses throughout the race course. The Stedman Clinic focuses on people that are active and it all starts with kids and being outdoors. Well, we love to give back to the community and this is a great community event for us to be involved in. I don't know, I wanted any challenge and I thought it would be fun. Probably the river. It was cold and it was hard and it was really fun. They're full of excitement and they are ready to take on the next challenge.


What's going on everybody? My name is John Hammond. Welcome back to the YouTube video still looking at the all army cyber stakes or ACI CTF So this challenge I want to showcase is called. Can you look this over? It's 450 points in the Michelinia's category The time recording it has 172 solves. It's Saturday and the game should end Sunday night So we'll see how many more that gets it says our ops guy found a malware author staging server We managed to exfiltrate the source to a back door. They're spreading they give us a download here So I'll grab that link location. I need you to report back once you've cracked their secret password Okay, so let's fire up a terminal. I'll hop on over to a directory here, and I'll make a directory for this Can you look this over? See the end of that guy and let's W get that file down There we go looks like a G zip file So I'll go ahead and gun zip it and it's still a tar so let's tar X ZVF all on that guy And there we go now we have a backdoor directory with a lot of files in here see me a lot of references to SSH I care about What this software really is? Seemly it's SSH right or open SSH. I want to determine what it actually might be version wise So I see this version header file. So let's cat that out just to take a look. Okay. It looks like it's open BSD That might just for be for BSD itself define SSH version open SSH 6.3. Okay so if this is a modified and manipulated version of Open SSH version 6.3, then I want to be able to take the differences between it and the original open SSH 6.3, so I'll try and go scour the internet For a download for open SSH version 6.3. Maybe I could download this somewhere Looks like a lot of vulnerability references. I want to download so if I search for download does that work for me? Linux from scratch offers it slack where seems to have some references This is just the release page on The open SSH website. Can I download it from them? Will they give me? There for open BSD ftp 8.2. Can I get 6.3? maybe oh well theirs isn't portable and The version number on this one is SSH portable. Maybe some of the others might have that Oh, yeah open SSH 6.3 slack where or the beyond Linux from scratch one has a download So let's get that one and that has the P1 that they reference here as well. So maybe that is good Let's W get that guy down Takes a little bit of time to download but he's cruising through it Okay, so now let's go ahead and gunzip that open SSH guy and tar to extract him one more time That should be an X not a Z There we go. Okay, so now we have open SSH 6.3. Let's cut out that version number to make sure it's the same looks to be Okay, fantastic. So what I'm gonna do is I'm actually gonna I want to be able to like compare all of these files at the exact same time It might be kind of dirty it might be kind of messy, but it might still at least work for me So if I grep tack R of everything it will return literally all the output of all the files that it can get I don't have to do this inside of the current directory So it doesn't include that parent name in that file path that's displayed over on the left here So if I grep all these and I put these in like a parent directory original dot text so Move up now. I have that original dot text for all of the files in the Original source code I can do the exact same thing in the back door if I grep tack R Everything and put that in like theirs dot text or what they kind of offer me now I have both the original and The back door all their files and I could compare them kind of easily because grep will allow me to do that since it's all source code Right, so I could potentially just diff the original and theirs. I might be able to see some Particularly interesting stuff. I also immediately see a little auth password and it says there's a static character hash the back door hash This guy here. So that looks like hex I could just steal this and work with it, but I did want to show you another trick and tool I really really like meld. It's a gooey diff viewer So if I were to make a file comparison, I could be able to go specify that can you look this over the original on the left and There's on the right once I start to compare all of this Meld will show me everything that's in both files So I would still be able to see okay These lines match on both the left-hand side for the original and the right-hand side for theirs Eventually it should start to find some differences You can see it's still chewing up there and it's taken a little bit more time to work through it all But I'll let this go and we'll start to go look at that hash But I want to show you where you could potentially see it with that tool as well Let's grab this hash.  Let's remove all of the comma So let's go ahead and grab this hash and I'll try and crack it online I'll use a little crack station just because that's kind of the quick and easy one If I spit that in there. Yep. I'm not a robot crack hashes It could not find it So when I kind of went back to the drawing board and I was looking at the diff here I know that well, okay, this is an md5 theoretically right md5 digest length We can assume they're using some md5 algorithm stuff. This has to be md5 So I try a little bit more googling. I did crack md5 hash online And eventually I found this little cmd5 guy and that one seemed to work for me So if I slap that into This it will decrypt it and that is my hash It is bb me zero y yours might be different I think they know they were doing some of the randomly generated stuff So if we were to go ahead and paste that in this can you look this over challenge? That is the whole flag that you need. It doesn't need the like aci Curly braces and the regular flag format. So that was that that was that challenge Just being able to simply kind of take a look at the differences here Using all the files all at once I tend to like that technique because I could really see Okay, this is all of the output from either side In any every single file because there wasn't going to be a ton And I mean if there were going to be a ton then I could look through it with meld Which was awesome But the auth.c and auth.pass would be pretty easy to detect once we had the right open ssh version number. So okay Hey, thank you guys so much for watching if you did I started if you guys did like this video Please do press that like button if you'd like to leave a comment That'd be fantastic if you'd like to subscribe do all those youtube algorithm things.

So we hear the ID Tech Act show and who are you? I'm David Arthur, I'm the CEO of Kazum Advanced Materials and we're exhibiting today, we're featuring Agent, our carbon nanotube hybrid transparent conducted film materials. So, how does it work? First of all, a carbon nanotube, a hybrid material is a case where you take one material, combine it with another where one plus one is much greater than two, something like ten or a hundred. And so in our carbon nanotube hybrid we have silver nanowires that are coated onto a surface and we have carbon nanotube materials that are printed on top of the silver nanowires. So this noodle-like structure and this rigid rod type structure is the hybrid material. So you do hybrid between the silver nano and carbon. That's exactly correct. And this carbon nanotube hybrid transparent conductive film is better than either material alone. The silver nanowires are highly conductive and highly transparent. And the carbon nanotubes are very robust materials. And the printing technology allows circuit patterns to be made very affordably. So the combination allows for better performance and lower cost. So what do you talk about here in this part? This is our carbon nanotube ink platform and basically we combine carbon nanotubes that we make. We have a factory in Norman, Oklahoma that makes the carbon nanotubes. We mix in polymer binder and then we have our own proprietary ink vehicle technology. The three of these ingredients get mixed together to make an ink. And this ink can be printed using conventional screen printing which is very convenient. It can be dried at low temperature which makes it compatible with plastic film substrates. And the end result is low cost printed flexible electronics. So here you have some demos showing off the implementation how this is set up to work. Like all these right here. So hi, so who are you? Hi, my name is Ken Clapperoth. I'm the Vice President of Marketing for CASM. And I'd like to show you some of the demonstrations that we have available for people that are coming to the show today. So what are these? We have a variety of different products that have been made by our technology. The transparent antennas give you better performance at a better form factor. Covering a broad range of spectrums for wireless. These can be put into or onto an existing platform. Transparent heaters that are formable and flexible. So this is hot? This is hot. So what's the advantage of doing the transparent heater? So the transparent heater allows you to place the heater in front of any object without it being seen. So in an automotive application where microwires might interfere with an optical camera, the transparent can be optically clear so it can ensure that all of your safety devices are still running. Would that be in the seat? It would be in the windshield. It could be in the headlamps and it could also be in the seat. And electric car companies are looking to get rid of the air conditioning that occurs where you're heating and cooling air and put the heating sources and cooling sources right next to where the people are for better mileage on the car. So how transparent there's got to be a little bit of loss of transparency, right? There is a little bit of loss of transparency but we have a full range of materials to give you everything from 99% VLT to 90% VLT and the conductivity that's necessary for the application. So are you able to make different recipes or what's it called? Yeah, the nice thing about the CNT Hybrid as David had mentioned is we can tune the recipe to be most effective to give you the combination of transparency and conductivity that's necessary for your application. Are you in mass deployment? Is it huge already? What are you doing? We are in deployment of the application with a variety of different customers in the variety industries. It's not in full mass production but we are working to fill out both customers and partners who can support us in bringing this to market. So this could be revolutionary for all kinds of consumer electronics and everything also? We are banking on it being revolutionary throughout the industry. It's the only CNT Hybrid that's on the market today and because it gives you advantages that the others do not we think this will be a real game changer. So let's say if you put it for example on the phone or tablet or something like that, what does it improve in the device? So the first thing is it gives better formability and flexibility so for the new flexible format phones that are coming out you've seen some very spectacular failures that have happened. As David had mentioned the CNTs encapsulate the silver so if you're doing a lot of flexing and folding it gives you redundancy there at the joint where it's most needed. Are you talking about the reviewers who are testing out the Galaxy Fold and then they had some kind of issues with the screen breaking or something? Does it have anything to do with the part that you're doing or is it maybe the flexible AMOLED is also fragile? So the failure point in any of those is going to be at the joint and if you've looked at any of the models of the phones that are on the market today they have very complex and very precise hinges to prevent any kind of cross twisting and it's that twisting that can cause the failure. So in both Samsung and in Huawei you can see that they've taken different approaches but they put a lot of effort into making sure that that bending is just across the axis and it doesn't twist. So how's the performance difference between glass and your solution? Is it possible that the consumer would be 100% happy with the efficiency of the system? Yeah, so we are certainly going after the flexible market. We're not really interested in going after IT on glass. IT on glass is very mature and very stable and so if the customer wants to just be on a glass substrate we invite them to continue with that but if they have any need for flexibility, they have any need for formability then our solution provides a superior solution. And he is showing touch screen? Yeah, so we have a variety of different touch screens. So there's one on top of the other. So one is a resistive touch and the other is a capacitive touch. So in both of those you can see it's really quite transparent. What's the happening on the side here, the tracks? So those are the traces that carry the signal back to the controller. So generally those are off the screen in a bezel somewhere so they're printed in silver that's common practice. But people like to do those bezel less devices. Are you able to be bezel less or is it specific to your technology, these tracks? No, the tracks are typical to any flexible printed circuit and we can do our best to hide those in an area where they won't be conspicuous to the users. Nice. And what's this part here? So this is transparent circuitry so if you're an automotive manufacturer and you'd like to put LEDs in the middle of a sculpted surface, this is technology that allows you to place the LEDs right where you need them. So you can put LEDs right in the middle of the device? Correct. So think of smart surfaces today. Smart surfaces are very popular. People want to be able to put touch interfaces and responsive LEDs in the middle of a sculpted surface. This technology allows you to do that. And this is an example of thermo-forming so there is unformed and formed. You can see that we've printed the circuit a little bit heavier so you can actually see the difference. But even forming to this shape of a dome it still maintains the conductivity that's necessary. That's what's more like formed, what's called formed electronics? Yeah, in mold electronics or formed electronics this is the direction that... It's also huge. It's also going to be huge, right? Correct. People are automotive companies want to go this way. You can use this technology to build the heaters into headlamps so you can see the headlamps on cars today are very sculpted. And how about this one? So this is a particular invention that we have. We're selling in two different forms. So this is called our RF shielding film and what this does is it protects users of cellular phones from radiation due to RF signals. So this is a particular pattern in a particular recipe of our technology that will actually direct cell phone signals away from the user and back towards the antenna so it does not degrade antenna performance but it does lower SAR exposure to the user by 25% or more depending upon the phone model. And it can be in an OEM installation which is the thin film or aftermarket which is the screen protector. And this is right on the screen the part that connects, that touches the ear and everything. Correct. For the aftermarket version it's a replacement to the screen protector that you might be using today. The best installation though is in the OEM situation where we put it into the display module it actually provides better protection so we invite any of the cell phone manufacturers to come see us if they're struggling with how to balance signal strength for 5G and protecting the users from exposure.  They say it is more all kinds of stuff happening with the spectrum and there might be a selling point to say that you have a phone that's safer. Correct. And what we're looking to do is talk to the design engineers because what this allows them to do is tune their balance between RF energy output that they need in order to get the signal quality with 5G and the exposure to the user. So they don't have to make the compromise anymore. They can bump up the signal strength to get to the 5G clarity that they need but they can also provide this film that gives the SAR exposure. And how about if we go over there what do you talk about on the screen? People can Google CNT Hybrid to see more stuff. Yeah, so we have a website at chasm. You can visit us on chasmtech.com or you can Google CNT Hybrid and it will bring you to our website where we have more information that people can see and interact with. What more has been shown in this video? So this is a thermal heating video. This is one of our transparent heaters as it goes through the heating cycle. This is a one-to-ones time. It will go up to 50 degrees C. This is the response rate that you can experience with our heaters. Is something about the heating right there? Is this some other? Yeah, this is a variety of different samples that we offer to customers. So a range of the recipes that we talked about earlier. You can see the different types of transparency that's available with the different versions. Plus this is an example of one of those heaters that's been printed showing the bus bars and how the material is put down. So you have been working on this for a while but what's going to happen next? What do you think is in the company 2020 is going to be a big year for this? 2020 I think is going to be an extremely big year for the company. We're working with Lighthouse name customers in all the different industries. Design and wins to their next generation products that they're developing. So we're going to have a big year with respect to sales to end customers. But we're also cultivating a group of preferred integration partners that can help us bring this to market. And where are you based and what are you working on? We are based in Canton, Massachusetts and we have a manufacturing facility in Norman, Oklahoma. So between those two facilities we cover both R&D and manufacturing of the product line that's known as agent. Thank you.
