Okay, how are you? Oh, good. Good morning. But it's a lot easier to go up. It's to do it. So that means you have to get in closer to the fire.  So come in low, get in close to the fire, and sweep from left to right, push into the fire across, get away from it. Oh, we got to go again. Just talk to somebody else. Just talk to the whole car. Back and forth, back and forth. The thing I want to say is that it's easy to want to use it or not. We had to change the galley. It kept holding. This is the prototype. It was exactly like this. It doesn't work as easy as this one. It's going to take a little manipulation, because if you just try like this, drink it. And 1G, this will seal off here eventually. Or you can take this package and hold it down and consume it down to the last middle layer. The other thing I noticed right away is this does not retain the straw as well as the other containers do. It should have the same... It's right on the base, too. This is really weak. There was one of them. There's no septum. No septum? That's what the problem is. That would be a real problem. When you get to the end of the... This is like emptying a gas can without a breather tube. Oh boy, you should have milked cows before. See, I like the beverage containers. The very first one we're going to try is the beef goulash. Do you want to try opening it? These silver packages are commercial products. Just retort packages? Yeah. Whose are they, by the way? Company called Truth Brothers. Do they package under their own name or do they package under others? Just under their name and their... They just sell the institutions right now and they're selling the commercial retail market. Taking some of this stuff from different suppliers of the back package is pretty remarkable. We like these, but they're lower in calories and lower in sodium than the military packs of them. Are we pulling this one yet? Yeah. This particular option? I don't have to eat it all. Of course, we all make mistakes in OD on the first one. Beef stroganoffinables. Use your scissors to get into those. Tell her in space do you usually open it up as far as that, like you just did that one? Yeah. Go ahead and open it up. Except for sausage patties because they'll escape on you. If y'all need another plate, or some extra ones. Those get too messy. Tortillas nowadays? Yeah. There's one right there. And I vote that we pick the whole week, too. Do you like the whole week? Yeah. I've never tried one. That's good. That's really good. Just a little more flavor than that. Typically, you have to separate these both weeks. I think that's why I like it. Yeah. I got tremendous interest from the Japanese people when I went to our space meeting. They mentioned two names. I don't know how we're going to do it. I was sushi. But anyway, they liked the theme of having international food. And I got the support from ESA, European Space Agency. The French guys, they said that it's a very good idea and they're going to support. They're going to participate in our program. So, you think it's a good idea? Hardly. Something good. If you'll heard me that last from the bait chips and mushrooms, that wasn't a true one. It's a what? True it. It's from True It Brothers. Oh. Yes. So a step before Vox was fanned, was that correct? Uh, was fanned on. It's on. Okay. Check both courage valves. I just need to hear your ambit, because I'm so excited. A little bit over to your push. There you go. Courage valves two. To closed and locked. And ready for the check. How's your cooling? I've got full hot valve in, but it's not doing much. Good pressurized traffic. Need somebody to pressurize her? It's going to be close. Well, I got rigid tether here. So, that's all we call it. Good. So, I'll look at that. I think the main thing there is, and then this point, we haven't really looked at it in the water tank, but again, with those, I would bet, you got to take me out of the airlock, position Bruce, position me. Hook them on to a handrail somewhere after we're both in, because they're fairly massive things. Okay. Probably not worth risking the airlock wall. See you tomorrow. Okay. Check. Okay. Let's go to the EMU third. Oh, two actuators. Press. Check them closed. Okay. Okay. And periodically, just flex your arms and legs and stuff and make sure we don't, you know, you get cooling adequately. We're on the pre-greed spot. 50 minutes. Goodbye. Bye-bye. Bye-bye. I'll be back. Let's get a good look. Son of a bag stays in. That stays in. I wouldn't have discovered Charlie would have everything out of here. I'm gonna check. He's taking you out of your room. You want me to bring in a tether? Yeah, I'd like to see how we can imagine ourselves inverted, and we'll look at it again tomorrow, but I don't want to take a look at that. That was what I was going to ask you guys. You want me to read them to you and one of you do it? For the electric stuff, yeah, for the electric stuff, I guess you're ready. We'll look to it. Okay. Yeah. And we'll have to simulate this since you're not anywhere. Okay. Okay. You push out with five marks.  When we get to six, we'll get a little alert tone there. When we get to six, we'll get a gauge pressure and water pressure. 15.0 and 15.0. Check your gauge for suit pressure. 4.4. 4.2. All right. Okay, can't do this. Airlock depress valve to zero. Okay, going zero on my mark. Mark. And again, we check to make sure that the gauge and pressure on the suit does not exceed 5.5. Okay, Bruce, you can figure in the waste tethers for egress. We'll simulate that. Okay. Highlight. You're going... I am. There I am. EDA. You're starting all the way across. Press. Yeah, with the pad. One more. Okay. There you go. And the airlock DP-DT is about zero. Roger. I'm opening the other hatch. All right. Thanks, thanks, thanks.


Hey everyone, it is Derek Weeks with the Linux Foundation. I'm the Chief Marketing Officer here, and I am here to give you your biweekly update on what's been going on within the Linux Foundation. So we've had a number of exciting things going on in the past couple of weeks that have kept us all really busy. So let's dive into them. So first of all, you might have heard that last week Meta transitioned the pie torch, transitioned pie torch to the Linux Foundation. It will now live within the pie torch foundation inside the LF, really exciting news that happened there. And I think that one of the primary reasons why pie torch moved was to give it a more neutral home than what it had at Meta and also make more resources available to it in the community for education, for training, for collaboration that the Linux Foundation can provide. If you didn't catch the news last week, read one of our blogs on the Linux Foundation site or read the blogs on the pie torch site and want to catch a little more, we actually have a live fireside chat coming up with Dr. Ibrahim Haddad. He's going to be the Executive Director of the pie torch foundation and one of my colleagues here at the LF but he's going to be having this chat with Smith Chintala who is one of the co-creators of pie torch and has been working on that project since the very beginning. So really exciting fireside chat that is coming up next week, I believe it's September 28th but check that out on linuxfoundation.org just go into our resources and webinars page and you'll see that there. Additionally, we launched a new training course pie torch and deep learning for decision makers. So if you're wondering what is pie torch, how can I be using it? It is a machine learning framework that is used by over 18,000 organizations now but if you want to learn a little more about the business impact of pie torch and what it could mean to your organization, definitely take a look at that training. It's online and free and available from linuxfoundation's training and certification business. I'll also say that you're really interested in the backstory of pie torch and Smith who's one of the co-creators of pie torch just released earlier this morning on all your major podcast channels, our latest version of the untold stories of open source features Smith and I was just listening to it having completed the whole episode maybe halfway through some great background on his history and kind of what led him from the earliest stages of childhood and his interest in computers through his maybe atypical progress through education and different universities and thought leaders that he had worked with in the industry before co-creating pie torch. So fascinating story, definitely worth tuning into that. Again, the untold stories of open source, just Google search and you'll find it on Spotify, Amazon, Audible and other channels there. So, and again, just released this morning on that. So what do we have next? Things that we introduced last week, the open wallet foundation we announced last week when we are all in Dublin at open source summit Europe. This is the intent to build the open wallet foundation. This will likely form officially later this year. But if you think about what open wallet's going to do and be focused on, think about what's in your wallet today, whether it's money, whether it's ID, whether it's health insurance cards, whether it might be the key to your new automobile, those types of things. How do we get them from your physical wallet to your phone or the thing that you carry around that can house that information? And the open wallet foundation is not going to determine or build any new standards. They're not going to build a wallet itself, but they're going to look at how do we collaborate across industry to build capabilities for anyone to build their technology or their data or their information into these wallets that can be more interoperable across any platform. So definitely stay tuned for that. If you're interested in learning more or getting involved in that, go to openwallet.foundation. You can learn more about the efforts there that we've announced. Now, as we were in Dublin, which is an awesome city, we all had a really good time exploring the temple bar area there among others and visiting the great restaurants, sampling the great food and beer that they have in the city. We also spent time announcing Linux Foundation Europe. So if you went to linuxfoundation.eu, you can visit our new site there, learn more about Linux Foundation Europe. The site is available in local languages. So we have English versions, German versions, French, Italian and Spanish versions of the site that you can access up at the top. Just click on the globe and you can view and read that site in your own local language. But kind of why did we pull together a Linux Foundation Europe in the first place? There are a lot of reasons from where open source is going in Europe, the investments that open source in Europe is getting in supporting billions and billions of dollars in innovation in the region, but also working with academic researchers and universities within the region, as well as government institutions that want to build more open source programs into their practices. One of the great examples that was revealed last week on stage in Dublin when we were talking about launching Linux Foundation Europe came from SAP. They were talking about at the very beginning of the COVID pandemic, the German government came to them and said, we really need help with contact tracing and developing programs that can help us manage all of these different kinds of efforts that we're trying to deal with during the pandemic. And the German government was reaching out to them for their development expertise. And as soon as they got into this and said, yes, we'll do anything to support this, they realized they needed certainly more than just SAP involved. And whether that was local governments or other businesses or healthcare, what have you to work on and collaborate on this, they also realized that efforts like that should not live within SAP, that they should be housed within the open source community. And so for a specific effort like that that was initiated by the German government involving German entities, it wouldn't make sense to say, if we want to open source an initiative like that to have it go and be housed at the Linux Foundation. While we're a global entity, a lot of people could say, well, that's kind of housing it outside of Europe or housing it in this global home. Why not have something closer to home and the Linux Foundation Europe now provides an opportunity for open source projects or initiatives like that to thrive within their own regions and be more specific to what's going on there. We did release our European Spotlight Report from LF Research as well last week. So again, go to linuxfoundation.org. We have a new website or newly designed. It's a lot easier to navigate, look in our research section and you can find it there. You can also find it on linuxfoundation.eu and it talks about open source practices and public and private sector. It talks about open source program offices. It talks about how open sources influencing billions of dollars in innovation across the region. So definitely worth checking that out there. Now moving forward, some couple other things coming up. We have Open3DCon coming up in mid October that's October 17th through 19th in Austin. They just introduced a metaverse track there within the conference. We have a couple of different speakers. Bryce Adelstein-Lelbach from NVIDIA is gonna be on the agenda as well as Deb Nicholson from the Python Software Foundation and of course our GM at Open3D Foundation, Royle O'Brien is going to be on the agenda there. So if you want to learn more about what's happening in the metaverse or what's happening in Open3D gaming and initiatives there with Open3D Engine and other projects under that foundation head to Austin in mid October. We also have in mid October or toward the end, October 24th through the 28th, I and others will be in Detroit, Michigan for KubeCon and CloudNativeCon North America. So always a spectacular show, thousands of attendees there in person as well as online. Keynotes for that are going to be announced shortly. I know hotels are in really short demand or I should say high demand, so they're hard to find but definitely sign up for KubeCon. We can see you there either in person or virtually. So I know we have our chat is open for any questions that are coming in from the community. So I'll take a look at those as they come into the chat. I see one particular question that has come in here. What will the Linux foundation in Europe to be doing to help open source in Europe? So I of course covered that a little before in this update but there are a lot of initiatives not only just in software but open hardware initiatives. You may be familiar with risk five that is initiated or run out of Switzerland within Europe. So open hardware initiatives around semiconductors and semiconductor architectures that risk five is leading open data and open standards initiatives that are very important to the region can also be housed out of Linux foundation Europe. We have a ton of different companies that have come in to be part of this that are based in Europe that have projects that they want to bring in and create new standards for data and governance across open source within the region. So definitely take a look at that. Let's see other questions. Let's see, does PyTorch, what is on the horizon for PyTorch and interoperability with other projects? So the best way to get an understanding of what's going on with PyTorch is to just dive into the project itself. PyTorch.org has loads of information, information, content, tutorials, videos, documentation online. They have I think about 10 introduction tutorial videos that are there that you can work through that were built by the PyTorch team and PyTorch community. So I would definitely start to dive in there. And also there's some great videos on the site of various use cases from anything from veterinary clinics helping pets to Amazon, improving shopping experiences to Dolby, improving sound in different environments. And you name it Tesla of course with self-driving car and a whole host of other use cases that are there described by the people that are using PyTorch within those environments. But as well as I mentioned earlier, we have a fireside chat with Ibrahim and submit next week on I think it's September 28th, check out our webinars page at linuxfoundation.org to find more there. It doesn't look like we have any other questions and we've been about 13 minutes in. So I'm gonna tune off or tune out for this week and end the stream, but definitely come back, subscribe, follow us more and certainly follow us on Twitter, LinkedIn and other social channels that you may follow for more updates on what's happening with the Linux Foundation. That's about it and I'll see you again in a few weeks. Bye.


This is the learning outcome for the student and at the end of this session student will be able to explain the basics of repair and rehabilitation. Actually, repair rehabilitation is very vast big topic that is a research area also but student at least they should know the what are the basics of repair and rehabilitation. This is the basic idea behind this video. Now, let us see the introduction why any structure any building is in need of repair or is in need of rehabilitation that is the main thing. First thing is the when the structure structure components are subjected to distress and the distress in the building is common thing or these are the common occurrences. Third thing is when any building element or component is subjected to crack why it is subjected to crack when the stress in it is reaching the limit of its strength then the crack formation is possible.  So gravity load as well as seismic load or wind load these two are the causes of stresses which are arising in the building components and one more last reason the thermal movements may be expansion or contraction due to temperature changes, moisture changes, chemical action, weathering action these are also causing deformations internally in the material of building. So let us see distress how it can be classified there are two ways to classify the distress one is structural second is non-structural. Let us see what is mean by structural distress if the distress is due to the faulty design faulty design calculations consideration of the loads or due to the faulty construction practices in appropriate practices or last is overloading you will find structural distress in the building. Next is these types of distresses structural distress can endanger the safety of the building also. Now let us see the example for example when overloading is done on any flanger or beam RC beam member definitely extensive cracking you will observe for that beam and that is due to the overloading. Now in case of non-structural cracks or the cracks which are not for the structural component of because of the crack is forming instead of these reasons these are not end danger to the safety of the building but this may look unsightly and it create an impression of faulty work also in proper practice also. Let us see what is mean by non-structural distresses these types of distresses are induced because of stresses in the building components. These generally do not directly resulting structural weakening but the cracks which are non-structural cracks are subjected to the weathering actions atmospheric actions may enter into these cracks and the reinforcement rebar may be subjected to the corrosion and this render to the structure unsafe and finally it may need to collapse also. Now one question is for you you just pause the video and see this question and try to answer this there are two fill in the blanks this is dash dash crack do not directly result into structural weakening and faulty construction and overloading leads to dash dash crack. Now which types of cracks are due to these reasons that you have to answer pause the video think over that and give the answer. The answer is first is non-structural crack do not directly result in structural weakening and faulty construction overloading leads to structural crack this is the answer. Now we are talking about the distress then overloading all those things now finally what is the effect of all those that is the cracking that we are talking about and let us see what are what is the nature of crack and what are the causes of the crack. Now in building components which are subjected to the stresses if the stress tend to move the building away from the steep portion of the buildings which acts as a fixed point due to dimensional changes this is one reason second is in symmetrical structures the center of structure or whatever we can call as the center of resistance acts as a fixed point and movement of the symmetrical building takes place away from the center on either side this is the second reason third is a building as a whole can move easily in a vertical direction but it is horizontal movement in horizontal direction is restricted by the action of substructure and its foundation. So deflection of the building is possible deformations are possible but in horizontal direction its movement or translation is difficult that is why there may be reason of arising vertical cracks on walls and this is more frequent phenomena. The stresses in building components are of three natures one is tensile type of nature compressive nature or having shear stresses or shear nature. Now these cracks once these are forming then this will spoil the internal finish of the building by allowing moisture to percolate and this will increase the maintenance cost of your building the maintenance may be in the form of painting repetitive painting again plaster some repair and this will increase your maintenance cost. Now it is necessary to stitch or seal or stitching or sealing of the cracks is required this is necessary and need where the cracks are formed. Now most of the material in the building it may be mortar concrete it may be masonry all these are very strong in compression but these are weak in shear and tension. So forces of small magnitude of tension or shear type may cause tension tensile or shear stresses and will result into cracking. So the cracking phenomena is very often in the building this is because of this reason. So let us see what is the classification of the cracks and this depends upon based on its width of crack. Now thin crack it is always less than 1 mm in width medium crack it is having width of 1 to 2 mm and wide crack is called as when the width is more than 2 mm. Now this is explaining the nature of the crack or even the type pattern of the crack. Cracks may be of uniform width throughout or may be narrow at 1 n and gradually gets wider at the other end. This is entirely complex phenomena what is the type of crack how it is developed. Next is cracks may be straight tapered to the map pattern random direction wise it is vertical horizontal or diagonal this may be the different patterns of the cracks. Crack may be at the surface or it may extend to the full depth of the member also it may be beam column or it may be a walls closely fine cracks at surface of material is called as grazing. So this phenomena is called as grazing when very fine cracks are on the surface of the plaster basically mapping we can call. Cracks due to different causes have different characteristics and by careful observation only of these characteristics we can diagnosis or we can diagnose the causes of cracking and the adopt we can adopt appropriate remedial treatment for that type of crack. Now what is the way to understand this entire problem first is a visual investigation of the concrete. So this investigation technique can be broadly classified as destructive or non-destructive now how that can be decided we should first visualize visual investigation and walk around the survey we should carry out and it should be taken to decide what type of technique is to be used for that type of cracking. Next is photography and notes should be taken from the site concrete site concrete. Digital photography of large area is helpful in documenting overall condition. So overall condition of the building then afterward they will whenever the photograph is taken in detail you can see very closely you can see what is overall condition of that concrete. Now close-up views can be used to check details such as crack width and its direction. So based on the crack formation and its direction the diagnosis can be made. Now these are the binoculars, telephoto lenses which are used to get the more accurate information and record the same for further use. Visual investigation involves looking for and analyzing cracks. So different phenomena are also explained here spalling of concrete or fine cracks or any other call such defense which can be seen without digging or scratching the surface of the structure or its element. Now to aid this visual examination the following checklist is made and the information which shall be sure should be collected in this checklist this just be as follows. First is the details of owner and occupier next thing is the type of occupancy also. So this detail must be taken first on site then the type of the structure whether this is RC structure, load bearing structure, stone masonry structure, brick masonry structure the type of structure is important. Next the dimensions, dimensions of the structure or structure element in case of building it must be taken at the length level it must be taken at the floor level. In case of the members the exact member irrespective of its extent the member shall be measured as it is which is actual on site. Now the interconnection of element that is also important the interconnection is the connection between walls, connection between the wall to rope, connection between wall to foundation also this is possible only in load bearing wall to foundation. Now material information what is brick masonry, what type of mortar is used plastering, internal plastering, external plastering then the material like concrete, grade of the concrete what was considered during the design and execution this material information is required. Now orientation of the building or building component with respect to north that is also important. Most important is the climatic condition prevailing and wind direction. So the climatic condition prevailing that is very important and based on that the what weathering actions have taken place and what damage that is made to the structure structure component because of weathering action that can be also. The science of the deterioration age of the building and details of the maintenance and previous repair of this. These details are also important. Now these are the equipment and accessories that will helpful in visual examination first is building drawing, layout plan, camera, binoculars, magnifying glass, flashlight, a compass, tape record. These are the references for this video. Thank you.
