 Good afternoon. I want to thank all of you for joining this important lecture demonstration. I mentioned that you would save thousands of rupees and in fact the convenience you would get out of this is priceless. I am going to demonstrate that. So, I will get started with the slides. So, I have in fact named this talk itself Sylab code for 65,000 solved examples of science and engineering textbooks. In fact, this project is Sylab textbook companion and we are delivering this through the Pandit Madan Mohan Malaviya National Mission on Teachers and Teaching. This project has been coordinated by Fossee, the textbook companion and there are many other interesting things we will talk about. In fact, you will also see some of the team members of the spoken tutorial project. So, let me go to the outline. So, this is the way I am going to conduct this session. I am going to explain why we need to use Sylab and then Sylab textbook companion. I plan to devote quite a bit of time on this topic. This is the one that has 65,000 examples already coded in Sylab, already available to you. And then we have a very exciting activity called lab migration. I want to talk about that also. Sylab toolbox is the ongoing work at IIT Bombay in collaboration with students from across the country. In fact, this Sylab textbook companion has been done with the help of more than 1000 students and faculty members from colleges such as yours. Then I want to talk about forum for discussions. This is the way we will take forward after today's meeting. People have asked questions, how do we remain in touch? What happens if we have a question? Will somebody be able to answer? The answer is yes. They will be able to answer. We will be able to answer and that will be through the forum that I will show later. How to use Sylab? For example, after doing all this, somebody could say, hey, you know, all this is fine, but how do I get started with Sylab? I am going to talk about that. That is where I will actually talk about our spoken tutorial team also. We have trained more than 2 lakh students and faculty members on the use of Sylab. The same method can be made available to all of you in case you have difficulty in getting started with Sylab. There are, of course, there are some experts amongst you and they can contribute a lot more. In fact, some of you are so good that you can teach lot of things to us. So, you are, I mean, we would really invite you to become our partner and you want to lead this, lead some of the activities. So, I am going to talk about that also towards the end of this presentation. So, let us get started with why Sylab? The main thing is free and open source software. You can have it running on your eyeball laptop if you want. You can have it running on any machine. In fact, later on I am going to show Sylab running on the cloud which you can make available through your iPhone if you want, your Android phone if you want, any smartphone for that matter. You can do it through any tablet. You can do this while travelling and so on. All that is possible because Sylab is open source. We can make this available to you. It is available absolutely free of cost. Commercial licenses imply that students have access to them only when they are in the college. What happens when they go home? What happens when they go to the hostel? Do they have access to it? And it is always a problem. If it is Sylab, then they have unlimited license. You can have any number of copies and use them legally, not only in academia, but also in industry because some of you could be consulting for some companies. An industry friend might have given you a small project. The licensing that you have for commercial software typically restrict you to academic activity. By the way, helping an industry is not considered an academic activity and typically commercial software license would cost 100 times if you want to solve an industry problem. And in fact, if you solve that problem, if you attempt solving that problem without telling the license provider, it may be a violation and legal action in theory can be taken against you. So, I tell Sylab is very good. It answers all these questions. It is also possible that some of your students could become entrepreneurs. Now, once again entrepreneur means it is an industrial activity. It is no longer an academic activity. And what about the investment? It becomes very expensive. They have to buy commercial software, any commercial software whereas Sylab is open source software. And the initial investment is saved from them. So, seed money that the startups get can be utilized for something lot more important. In fact, I would say that using commercial software in academia is equivalent to is almost like using books that the students cannot take outside your college compound. Whereas if you use open source software, they are free to use them in your college, outside wherever they are and so on and so forth while traveling, coming to college, going back home, all kinds of things. So, Sylab is one such great software. So, let us focus on Sylab in the rest of this presentation. Sylab is free and open source software. It is a great substitute for MATLAB. In fact, if you start using it, you will see that comments are very similar to MATLAB. And I would say that it is about 95 percent compatible. And so, it is very easy to migrate a code that you might already have in let us say in MATLAB into Sylab. And XCOS is a good replacement for Simulink. Some people immediately ask when I talk about open source equivalent, people immediately ask Octave. And they ask why not Octave? Why are you using Sylab? Here is the answer. Octave does not have an equivalent of Simulink. I hear some of you saying that unless there is an equivalent of Simulink, I will not switch over. So, Sylab has it. Having said that Sylab has no problems with Octave. As a matter of fact, the open source software, all of them work together. They all have open API. I will show you later that Sylab will, Sylab works with Octave. In fact, we do make use of functions that are written in Octave inside Sylab. As a matter of fact, all of Octave functions are available now in Sylab. So, we have done that work. I will discuss that when we go to the toolbox part that comes later on in this lecture demonstration. So, let us go to the next slide. Sylab is an excellent computational environment. Lynpac, Icepack, Lopac. These are heavy-duty numerical engines. These have been developed by experts I would say 30, 40 years ago. That 30, 40 years is an important statement because these packages have been used by millions of people all over the world for 30, 40 years. That means if there is any bug that has been completely identified, isolated and solved. So, all these amazing software tools are available on Sylab. In fact, I can say that Sylab is built on these numerical engines, state-of-the-art numerical engines. Not only that, it has other software like Darcyl and Vodeepag which could be available only in Sylab because of licensing requirement. For example, if there is a software that says, look, I am open-source software. If you want to use me, you also have to be open-source software. Then obviously, commercial software cannot use that. Such software is also available on Sylab. So, to tell more about how reliable is Sylab. So, here I have this slide on that. CNES is an acronym. It is a French acronym. It is like our ISRO. This is the French Aerospace Corporation. You may not have heard of it, but you would have heard of Arian rockets that have been launched by CNES. In fact, GSAT 16. In fact, even subsequent to that, there was a GSAT launch. It was done by Arian. So, India's GSAT 16 launched. If you see here and I am not sure whether you can see it, let me make it bigger. I will just say no thanks. So, if you see here, it reads this and you can say that this GSAT 16 was launched by the European Launcher Arian 5. So, this is the Arian I am talking about and this is the product of CNES, which is the French Aerospace Organization. So, you saw that Arian launches our satellite. Possibly, we are using that satellite for the current communication. Maybe that satellite is actually making sure that whatever I talk can be heard by you. Now, so what is the big deal? What is the connection between that and Sylab? It turns out that CNES relies on Sylab for many critical calculations. For example, I want to show you the talk by T Martin of CNES on Sylab. Let me show you where it is. I have opened all of this. So, here is I have gone to this page. It is the Sylab Tech. In fact, there was a meeting first ever Sylab user conference. Let me make this bigger Sylab Tech and you can see the keynote address. I gave the keynote address here. You can see that this was held in Paris National Mission on Education through ICT. In fact, I talked about open source software in the year 2009 in Paris that was the keynote address. In fact, there I mentioned about the textbook companion for the first time ever. But if you go down here, you see this use of Sylab for space mission analysis by T Martin CNES. Let me click this and it will take you to the next page. If you want to see the slides, you can download this, but I am not going to click that. Basically, what he says is we make it bigger. So, you can actually see it better. So, Sylab has been used successfully. Now, for several years in CNES, which is a French National Space Agency and so, he talks about the presentation will explain how Sylab is used throughout the satellite life cycle from the early trajectory design phases up to the operations and so on and so forth. In fact, if you see this slides, he goes on talking about how Sylab is used extensively in French Aerospace Corporation that launches Arian rockets, which in turn places many of our satellites in the orbit. Now, as a matter of fact, I was the session chairman for this talk and I asked Mr. Martin, do not you use anything other than Sylab? You seem to be using Sylab for everything. So, if they can launch Arian rockets and place our satellites in orbit using Sylab, it can certainly be used for your requirement namely optimization, differential equation and FFT, all kinds of things name it Sylab can do that. So, let me go to the next slide. Of course, there are few more industrial applications of Sylab also. I already have the link. So, let me just go and do this anyway, show it to you. So, here for example, open source model based systems engineering, model reduction for wind form optimization, this is enhanced ground proximity warning system, design of experiments and optimization of aircraft design. In fact, this is the one, I think this is another example from Arian. If I click this, it will probably take you there. So, every one of them has lot of things and they have hosted some of them. Here it is design of experiments and optimization of aircraft design and so, they talk about how they have you know done this work and so on. So, let me go back. So, anyway I gave samples of few more industrial applications of Sylab. Let us move on. So, this kind of completes the first part namely you know Sylab is great stuff. Sylab is great stuff, but it is not that it does not have problems. What are the problems? Good documents are missing in open source software because there is no company that is behind it to create this kind of documents. So, at the beginning of this our project, we said that look Sylab is a great stuff, we should promote it, we should make it easy for people to use. So, we came up with this solution called textbook companion. So, what is it? I will just show this to you. Go to the next slide. So, this is the second topic that I am going to textbook companion. We would also call it as TBC, textbook companion TBC. So, we started by saying why do not we use students for creating these documents? Documents are in short supply, we have lots of students, why do not we ask students to create documents? The problem is students are good in coding, but not in documentation. So, we said you know it is a problem because India has 10 lakh engineering students every year. So, that means in 4 years we have 40 lakh engineering students. If only they can do the documentation, it will be fantastic. We would we can cover all open source software, but they are bad in documentation. They are good in coding though. So, we said why do not we solve the inverse problem? What is the inverse problem? Ask the students to create code for existing documents. And what are existing documents for students? It is it is standard textbook. So, we said ask the students to write Sylab code for solved examples of standard textbooks. We are not talking about unsolved problems. We are talking about you know every book has solved example. The instructor, the author of the book gives an example, works it out. So, we ask the students why do not you write a Sylab code? And when you solve it using Sylab, go line by line and the result of every line should match the corresponding answer given in the book. Why answer is given? How do you know answer is given? It is a solved example. So, answer is given. So, it is easy to create, easy to validate and it can be easily contributed by the student who does not have to write a single line of documentation. Students write only code for these. If they do it for the whole book, a book typically has 70, 80 examples. Some bigger books have some 150, 120 examples whatever that is. If they do it for a whole book, we call it one TBC. That is one TBC has textbook companion of a particular book has Sylab code for all solved problems of that book. But remember it has only the Sylab code. It has only Sylab code. It has no text. It has no documentation. If you want to understand it, you have to open the book. As a result, we are not violating any copyright because nothing from the book is reproduced because this textbook has only code after code after code. One book is, if they do it for a whole book, we call it one textbook companion. And thanks to MHRD, thanks to the National Mission on Education through ICT that funded the FOSI project, we pay rupees 12,000 rupees for a student who creates one complete textbook. I will show you when I go to the website how one can access this, how one can contribute to this and so on. Let me go to the next slide. So, because we have lots of students and the students are good in coding, a student can say that look, I attended this class. This book is not already created. This book is not already covered in textbook companion. So, I want to take it up. So, they propose it and then we permit them and they do this. We have created more than 500 Sylab textbook companions. We have more than 500 Python textbook companions. You do the same thing with Python. It becomes a Python textbook companion. That is, for every solved problem, you give Python code. It becomes a Python textbook companion. So, we have eSim textbook companion. We have an open form textbook companion. We have open modelica textbook companion. We have just started our textbook companion. Your students can participate in all of these. I will show you more about this as we go along. So, our Sylab textbook companion. Of course, the focus in today's lecture demonstration is Sylab. We are of course, discussing Sylab TBC textbook companion. More than 1000 college students and faculty have contributed to this development. In the previous slide, I said more than 500. It turns out that it is actually more than 550 textbooks. And if you assume that there are 100 examples in each book, together it will be 55000 examples. It turns out that there are actually 65000 examples. These have been coded by 1000 college students and faculty of all colleges across the country. So, in fact, those of you who are watching this lecture demonstration, it is possible that some of your own students, maybe the past students have already contributed to this effort. Now, I am going to give a demonstration. So, I will give a demo of Sylab cloud on Garuda. Garuda is the cloud on which CEDAC creation, Garuda cloud. And this is in Bangalore. And we have hosted Sylab on top of that. I have given this demonstration from various parts of the world. So, now I am going to give this demonstration from. So, let me go there. So, let me go to Sylab on cloud. So, this is just a browser. I am using Chrome. You can use Chrome or Firefox or whatever it is. So, let me just add 1 plus 2. So, this goes to the Garuda cloud. So, you see the answer has 3, answer has come as 3. Of course, you do not need Sylab to add 1 and 2, but this gives an idea that Sylab can be used as a computing machine. I mean this cloud can be used for computing. So, what I am going to do now is I am going to show you the textbook company. Remember, we are talking about 550 textbooks available on Sylab cloud. It has 65000 examples. All of them are here. So, and these are classified under various categories. So, let me, I want to make it bigger. I got a feedback that it is difficult to see. I just did 1 plus 2. I got the answer 3. So, let me just see the category here. There are lots of topics. Well, let me take, I could choose anything. Let me choose control theory and control systems, which happens to be my field. And I will take BCCO, automatic control systems. Remember, this is the textbook companion we are going through. This cloud is capable of doing Sylab computation. I did 1 plus 2. It gave me the answer as 3. Now, I am saying I am going to use the same facility to run the textbook companion created by one of the 1000 students. So, here is the book that I have taken. What are other books? What are the other 550 books? I am going to show you later. Of course, you can actually go through this and browse this for yourself. So, I have selected automatic control systems. Now, let me select frequency domain analysis and let me choose body plot. The moment I select this, I have got the code. See this? I have got the code coming. So, now, let me execute. So, let me execute. Now, it is executing. The answer should come here. Remember, it goes to Garuda Cloud in Bangalore. This of course, requires that you need access to internet. Of course, you can do this through your smartphone while traveling for example, going by bus to your house. You just open the smartphone and you want to do the computation. You want to set a paper. You can do that. So, while it is executing, let me go to the server is unable to serve your request. Please try after some time. So, I think internet there seems to be some problem. We will come back to this page. I am going to ask my staff members to look into this why it is not working. In the meantime, I am going to show you some of the things, the textbook companion so that you do not have such problems. You can actually download all the code and keep it locally. So, let me, you want me to make it bigger. So, where did I come? I have come to sylab.in. Sylab.in and if you see on the left hand side, you have something called textbook companion project. So, let me click this. It actually explains what this is and it of course, talks about internship, guidelines for coding, hondorium, FAQ and so on. Here I am going to click this completed books. Let me click this. So, you can see the completed books here. It turns out that the total number of books completed as of today is 562 and these are all here. If I click this control theory and control systems, it takes me here. Remember this automatic control system that I was showing, but then it has 12 books. Similarly, if you go up fluid mechanics, there are 31 books, chemical engineering, 26 books and so on. So, here is thermodynamics, mechanical engineering, signal processing. So, let us take one of the very famous books in signal processing, digital signal processing by Procus. This is used in many top universities across the world. So, here it is and it says who is the contributor? Professor Senthil Kumar, Institute of Road and Transport Technology and you can download the Sylab code. Remember I told you that a book has about 100 examples, 120 examples depending on the size and all the solved examples have been coded and the Sylab code is available here. Now, if you click this, you will get the PDF file. Let me click this. So, here it is. It has come. Let me open this. So, you can see that. So, this is let me make it bigger. So, you can actually zoom it or you can see it bigger. This is the one I downloaded by the way. This is the PDF I downloaded. You can actually use it as a book. Remember the other thing that I told you was code of Sylab.sci file, .sci file. You can download the whole directory and keep. Here it is the same code in PDF version. So, this is a typical textbook companion available in a PDF form. And what does it have? It has if I just scroll down a little bit, if you just scroll down quickly, you will see that it has code after code after code. How do I access it? Well, it is very easy. All that you have to do is you go to the beginning and you say that, look, I want to see the code for example, 2.1.25. I want to see what is an odd signal. So, let me click this. So, here it is. So, this is for example, 2.1.25 odd signal and there are 16 lines of this code and so on. So, you can actually see this. Here is the PDF that I downloaded. And of course, you can say that, look, I do not want it for the whole book. I want to do this for only one chapter. Then you can say, I want it only for because basically sometimes people say, well, I want to know how to multiply 2 numbers 2 into 3. Then you say, no, no, you have to download the whole chapter. You have to download the whole book. You have to figure out how to use it, not required. You want to solve only one particular example. You want to get that code for that only. I tell you how to do that. So, here is the title of the chapter, design of design filters. You can download the entire code or you can say that, no, I want it for only for problem 8.3.6 which is IIR Butterworth Analog Filter.se. So, if I click this, it will download the code required for example, 8.36 alone so that you do not have to worry about the whole book. Of course, you can download the whole book and keep them if you want. But if you want to see only one thing, not get bothered by a lot of other clutter, you do not have to do that. So, I gave you example of Textbook Companion. Here is the typical Textbook Companion. So, let me close that. If I can download it and keep it as a book if I want and so I will close this also. I attempted to give a demo of Sila Cloud, but I will come back to you. So, how useful is this Textbook Companion? First of all, if a teacher says, look, I do not know how to use Sila, I will ask them what book are you using, what course are you teaching, what book are you using and here is the Textbook Companion. I already have Sila code for that. So, for example, if you want to say, I do not know how to access FFT, I do not know how to compute FFT, I am teaching this, you know, let us say signal processing book. So, I will say, all right, open that book, go to that example where FFT is done. Go to that particular chapter, go to that particular example. It could be example 5.3.8, then come to the corresponding Textbook Companion, open 5.3.8. Now, so it would have been explained. All that you have to do is, you have to take it, run it and then you have it working. Now, of course, you could ask what is the guarantee that book will be there in the Textbook Companion? The likelihood is very high because it has 550 books. Not only that, we made sure that all AACTE approved books, all AACTE recommended books are already covered in Textbook Companion. As a matter of fact, we gave 20 percent extra Honduriam to any student who took up an AACTE approved book. So, for those books, we gave a special incentive of additional 20 percent Honduriam and we got it done. So, it is likely that, so all AACTE approved textbooks are already available and there are many other books of course, we have covered many of them as well. We have 550 books. So, if in spite of that, your book is not covered, it is a standard textbook, it is a great textbook and so on. Please, I would want you to do that. I would want a bright student from your class to say, to propose to us, I would create this Textbook Companion. So, we will include that also in the future and we pay them, that student, that bright student of yours, a Honduriam certificate and so on. Of course, it will appear on the front page, it will say that such and such person from such and such college created the Textbook Companion and it is used by Sylab community throughout the world. That is a great recognition for you, isn't it? So, you can, this is the way to use it in Sylab. So, it is useful to 99 percent. Why am I saying 99 percent? A software, proprietary software like Matlab is vast. In fact, even Sylab is vast. It turns out that most people do not use even 1 percent of it. Most people do not use even 1 percent of it. For them, that is, I would say 99 percent of our population, what we have in the Sylab Textbook Companion is good enough. By the way, I just came to know that the cloud is working. So, this is, remember, this is what we have taken. So, let me execute this. You can see this wheel spinning. That means, it is gone to Garuda cloud. Let us see whether we get the result. There you are. Here is the body plot. Remember, we are running body plot. See, this is 9.15 body plot. Here it is. I can download it. You know, if I download it, it will come down here and then you can take it, take a printout and so on. But, let me close it now. But, notice the results come here. See the results come here. You can see the transfer function. 2500 divided by this whole thing and that comes here. This is the result. And for those of you who are familiar with this GM, GM stands for gain margin. It is 14.8. Phase margin is 31.71. How to do that? It is already given here. GM is this. Phase margin is this. Now, supposing a student says, hey, what will happen if the transfer function gain is not 2500, but it becomes, let us say, 5000. The numerator becomes 5000. So, let me change it to 5000. I can change it. Remember, I added 1 and 2. So, you can do all kinds of calculation. Naturally, I can change the 2500 to 5000. And let me go back and execute this once again. And I want to ask you a small quiz. Will the margins go up or down? I have increased the gain. So, of course, gain should come down. I mean, your gain margin should come down. Phase margin should come down. We will see whether that happens. Of course, you will see the numerator also changing from 2500 to 5000 now. I have a feeling that it is slow because there it is. Unable to serve your request, please try after some time. I will come back to this later. So, what I will do next is to go to the slides. Let us go to the next slide. This is an, I believe that Syla text to companion is an amazing thing. Why? Because, see, you look at me. I am getting old. Can you see that? So, the problem is, you know, my memory is very bad. I forget things. For example, I do not know what command to use. And once I, even if I find the command, I do not know the syntax. How many arguments? Which argument should come first? Again, so I do not remember all of this. I see many of you telling, well, Matapita, Google Devam. Yes, we all know that. And I am going to follow that, but to some extent. So, let me just show you that. So, this is the true story, true story. I had a quiz to set for my students. And I wanted to set a question in partial fraction expansion. I was teaching a first control course, first quiz. So, I said, let us test the students on partial fraction expansion. Now, it turns out that I did not remember the command for partial fraction expansion in Sylab. So, what did I do? I turned to Google. So, I said Sylab partial fraction expansion. So, it gave the answer as PFSS. See this is PFSS. So, this is fine. But my experience with contacting Google to find the syntax has not really worked, because it will give a million hits. And it is very difficult to figure out what happened. So, what I said? So, I need to open that website, because I opened a new webpage for you people. So, let us go there. Let us do it. Let me go to Sylab.in. Under Sylab.in, there is a search button on top. You can see the TBC code search. What does it do? Remember, I have 65,000 examples already coded. I will search amongst the 65,000 examples. So, in other words, I do not depend on Google, but I do a search within my textbook companion. What do I search for? I search for PFSS. What is this PFSS? This is name of this command. How did I get it? From Google. From Google search, I got the name of the command. In order to find the syntax, I come here and do a TBC code search. And it says, I search for PFSS. Remember, this is what I got from Google search. When I do that, it searches and says 140 results found. Amongst the 65,000 examples, there are 140 examples that talk about PFSS. And it says what these books are, 1, 2 and so on. I go down and I say, no, no, I am not familiar with this and so on. Finally, when I come to this number 27, I say, hey, I use this book when I was a student. Let me view this example. And it already takes me to Sylab on cloud. So, what I did on that day was, I got this example. It tells me, you know, numerator has to be created like this, like this. Denominator has to be created like this. And then, the transfer function, numerator by denominator. And then, I just have to say PFSS. It tells exactly how to use it. So, I can use it directly. I run it. Let me see if I can run it this cloud. If so, I will be able to get the answer. There it is. Denominator. So, these are the partial fractions. You can see the partial fraction. Here is the partial fraction. Denominator is s plus 2. The other one is s minus 2. If I want, I can go back and change, run it and so on. So, let me remove this semicolon. For example, if you see here, if you see here, only denominator is displayed, that you know because denominator does not have a semicolon. Numerator has a semicolon. Let me remove this semicolon so that I can see the numerator also. I mean, those of you are familiar with Matlab or Sylab or Octave will know this. So, let me execute this once again. So, hopefully, we will get NUM here. Hey, this is giving some other answer. Not sure what is happening. I think a lot of people are once again using. So, let me try to run it. Let us see whether it works. So, anyway you saw that at least 2500, the previous example you all saw it. Oh, this is the body plot that has come. So, actually this problem is happening because now we are using it on a view server and it behaves in an unpredictable way. This is the answer I got for earlier. Oh, it put me. So, it has actually both are connected. It does not know that it has to pipe it. It is a problem of a view not of the server. So, let us go back and execute this. Let us see what happens. I should close this. Let me close this. I should close this also. Let me close this also. So, this is executing. Here it is and you can see now it has 5000 in numerator and you can also see the margins lower now. Can you see that? Previously, it was 14 and 30. Now, it has come to 8 and 17. Anyway, so I was trying to do too many things. But obviously, you will not be doing solving two problems simultaneously. You will be solving only one problem at a time. So, let me come back to this. Search within this. Remember this. Let me give this example again. This is that partial fraction expansion. I open it. So, when I open it, I will go and close this so that there is no, this browser does not get confused. Actually, this is not a problem of a view. It is a problem of the browser, the way it is designed. So, it does not know which window it should pipe it to. Remember, I wanted to remove this numerator. Let me remove this. Let me execute this. There it is. Now, you can see the numerator also. I can see it because I removed the semicolon from here. Numerator, denominator. Then this is a partial fraction 1, partial fraction 2 and so on. So, of course, what you can do is you can take this example, you can modify it and give it. You can give the example as it is to your students as assignment, lab problem, your exam problem, your whatever quiz, whatever it is. It turns out that in this particular example, I use this example as it is. Without any change, I gave it as a problem to my students and they all did this computing. Let us go back to our slides. So, this is the code search to locate syntax. I mean, this is going to give you so much help for all of you. You have to set problems. You have to set new problems, all kinds of problems and you have it now. All your examples are available on your fingertip. Now, you can do this while traveling. You might be traveling, you have a smartphone. You can do that and you get your problem set for your exam, for your assignment, lab and so on. And this is available for 65,000 examples of standard textbooks. Let us go to the next slide. So, the next one, lab migration. So, do you want to migrate your lab to SILab? It is a great thing because if you want to use a commercial package in your lab, there is a problem because you have some limited number of licenses. Even of course, if you have limited license also, once students go home, they cannot access it. Once they go to hostels, they may not be able to access it. They may not be able to access it while they are traveling and so on. So, there are many problems. It turns out that in IIT, Bombay, we have limited licenses of MATLAB. So, it turns out that as soon as somebody access it, that license gets locked up for 4 hours. Even if they just use it only once, that gets locked up for 4 hours, then nobody else can use it during that time. That means that licenses get consumed quickly. You do not have enough licenses. So, supposing you have a problem like this, you want to migrate your lab to SILab, we will help you. So, that infinite number of people can use. Everybody can have their own copy. They can do this on the smartphone like I showed you. They can do it on tablet like I showed you. They can download it on their low-cost laptop and so on and so forth on Windows platform, Mac platform, Linux platform, does not matter whatever that platform is, SILab will run for you. So, do you want to migrate your lab to SILab? We are ready to help you. State your lab experiments. You code them in SILab. If you say, look, I already know SILab. I know how to migrate. Let me migrate, but I will share that for the community, to the community. Let everybody use it. We will give a hand rhodium and a certificate or supposing you say, look, I want to do this, but I do not know how to use it. Can you please convert this into SILab and give it to me? We will do this for you and give you the SILab code for your experiments. And it can be done by experts, SILab experts from colleges. You will see in the next slide, many labs have already been migrated to SILab by experts across the country, from various colleges across the country. And they are ready to do this help, give this help for your college, so that you can migrate your lab also to SILab. So, let me show that here it is completed labs. So, you can see that there are many labs available. So, you can see down, there are totally 64 labs that are that have been migrated. You can see colleges that have done this. There is one VIT University Chennai, there is one Saint Xavier's Catholic College of Engineering and so on. There are many colleges, Vishwakarma Institute, Aryanet and so on. Besit, Anjuman, Takkur College. Besit has done lot of lab migrations as you can see. So, Mumbai based college. Now, if you want to say what is this look like? Let us say here is the one from, let us say, take this from Besit. Say antenna wave propagation, if I click this, then it gives the same thing, the way we saw the textual companion. So, let us download the PDF of solutions and it has come here. Let me open this and this is, let me zoom it. SILab manual for antenna wave propagation and you can actually go and see that. There are not too many problems, too many labs here. There seems to be only one here. So, let me take one more example. So, let me take this DSP, digital signal processing download of PDF of lab solutions. I have to download the PDF. If you download, you will get the SILab code. So, let me see what this looks like. So, let me zoom this and you can see lots of labs. So, it depends on the previous one that antenna lab has apparently only one experiment. Whereas, here this one has 13. Of course, this is a basic lab. Let us see that. So, periodogram based spectral estimation. So, it is all here. Once again it is the same way that we saw with the textual companion. So, you can download this. You can go back here. You can see all of them. It is possible that the lab that you want to migrate is already migrated by somebody else. Those experiments are already coded by somebody. So, all that you need to do is to propose to us that you want to migrate. We have some conditions. What are those? So, it is all here. Lab migration project. It says procedure, coding guidelines, hundredium completed labs. Completed labs. We saw 64. There are many more labs in progress. Let us click that. You can see that 15 more labs are happening. We would want all of you to propose labs, to migrate your labs from whatever software you are using to psi lab and the help is already available because all that you have to do is to go to the completed lab and then you can you know your experiments are probably already coded and already available. So, let me just go back. So, this is what I said. Do you want to migrate your lab to psi lab? We will help you state your lab experiment. You code them in psi lab. We will give you hundredium and certificate and we will put your name and say your college did this lab migration for the whole world to see or we can get them coded by psi lab experts from colleges. 65 labs already migrated. Actually, it is 64. 65th is almost going to be there. You can see that 15 are under progress. The next one that I want to talk about is building psi lab tool boxes. Some of you might say, hey, you know, all this is fine. 65,000 examples is it is going to be good enough for 99 percent of the people. What about that one percent? I belong to that one person. Can you please help me? So, we have indeed gone about building psi lab tool boxes. How do we build a toolbox? We identify open source software that have required functions. Basically, psi lab toolbox may not have enough functions. You want to do image processing. Some tool, some function is not there in psi lab or you want to do signal processing, you want to do optimization. It is not there. So, what we do is we identify those functions that are present in open source software. For example, we have Octave, we have OpenCV, we have IT++. This is for communication toolbox. We have IP op. This is a great optimization toolbox. Cayenne OR, this is a collection of lots of optimization code. You know, these are all available. Call them from psi lab using C, C++, Python, whatever is required. Call those things so that those functions are available. And as I mentioned earlier, these are all proven code. Octave is a fantastic software. IP is excellent software. OpenCV is the state of the art in image processing. We can call all of them from psi lab easily. We have done all of that. So, they run very fast because they are also compiled code. They are not interpreted code like, let us say, an ACI function, an interpreted function. These are compiled code. So, not only are they proven, but they also run very fast because they are compiled code. The end user in psi lab does not know all the details, key things or key things that they are actually calling a psi lab function. It is just that it goes and calls that code and you get that. So, to tell more about it. So, we have actually a paper that we wrote. Shamika is leading this effort, the toolbox effort. This developing psi lab toolbox is a multi-first approach. This is an IEEE paper. I uploaded, not sure whether it is available. I gave one more PDF file. Did you upload that? Is it here? So, can you show that? Yeah, here is the thing. So, here is this paper that I have uploaded. You can actually see this. So, this is something. All of you will have access to IEEE papers. You should be able to locate it. And we actually explained in this paper how we built toolboxes. For example, this talks about how we are using IT++, Octave and so on. It talks about the diagrammatically it explains how we built this and then optimization toolbox. How did we go about building? And this one actually talks about optimization toolbox. We go to the next page. This one talks about signal processing toolbox, our solution and so on. So, let me just go back to slides. So, this paper will be available. You will have access to IEEE proceedings. You can download this. Those of you who are interested, remember I am talking about the top 1 percent of the people who want to build toolboxes, who want to use toolboxes, we are ready to work with you. Let me go to the next slide. Now, where are these toolboxes available? These are one of them. Optimization toolbox is already released. Let me show that to you. Here is the atoms. So, you have to go to, I will make it bigger, but I do not know whether the URL will become bigger. But anyway, you can locate this silab. It is called HTTPS colon slash atoms.silab.org. So, once you go there, you can search for FOSI. I search and I got this FOSI optimization toolbox. Let me zoom it bigger. You can see this FOSI optimization toolbox. There are 2662 downloads. As of February 13, 2017, many more people have downloaded since that time. It is an amazing toolbox. FOSI optimization toolbox has everything that you would want in an optimization toolbox. It says on how it is available, what are the features, all functions and then for various systems, you can download and use them. And other toolboxes to be released shortly, code is available here. Let me show you what other toolbox are available. So, let me go to silab.in. What other toolbox are going to be available that I want to show you? Under that, you can see this. So, I went to silab.in. In that, you see FOSI silab toolbox. If you click this, all the toolboxes are listed here. Optimization toolbox, signal processing toolbox, image processing and computer vision toolbox, system identification toolbox, control system toolbox, silab to see toolbox, silab octave interface toolbox. Using this, you can call all of octave. And there are of course, some examples for lecture demonstration. Some of the examples that I have used are there. You can of course, go and access. These are not available, released yet under atoms, but they are going to be released soon. I am going to show you the progress of each of these toolboxes later. If there is an interest, we will give a demo of some of these toolboxes by Shamika as we go along. Maybe after I finish my presentation, Shamika can give a demo in case there is an interest. Let us go back to slides. So, here is the silab toolbox usage. Here is the number of MATLAB functions. Here is the corresponding number of silab functions that we have created. Most of them have been created by us. And of course, we have had lots of interns from colleges such as yours. Brightest students, we have had even 50 interns working with us, taking one toolbox and completing all the functions. Signal processing, we are almost there. Image processing, we are almost there. So, some of the missing functions are possibly not very important. Once again, these should be good enough for lots of people. Some of them we need help. If you have a bright student, you have a PhD from a great college, great institution and you want to contribute, create a toolbox, create a function, you know, you are most welcome. These are all the toolboxes that we are working on. This explains the progress in some other toolboxes. Let me go to the next slide. So, the next question. Now, topic number 5. Some of you asked me, all this is fine. But we want to interact with you. We have questions. How do we help you? Is there any help? I have an advanced question. I know how to use textbook companion. All that is fine. But I want to write a function. I need help. I want to become an intern. I need help. How do I communicate with you? So, for that, we have this forum. So, let us go to the forum. Let me go to fossey.infirst. Fossey is the umbrella organization. You can see that in that forums can be reached from here. But before I go to forums, I want to show you some other things that we are doing. So, Sylab you have already seen. Python is another activity, major activity. eSim is electronic circuit design simulation. We ourselves created this. This also could be useful. Let me make this slightly bigger so you can read it better. We have OSDAG. This is steel structure design. DWSim for chemical process simulation. Open foam, computational fluid dynamics. Open modelica. This is an amazing modeling and simulation environment. What tools I talked about and so on. There are many things available. We also have R. We started creating textbook companions on R. So, you can whatever I am going to talk about these forums, you can ask questions on any of these. So, let me go to I think it is in forums.fossey.in. So, let me just search. So, forums.fossey.in that is all. That is why we say Matapita Google Devam. So, here it is. You can ask questions. So, there are people who have asked questions. So, what we would want you to do is, do you have a question? Do you want to talk to us? Do you have a question on toolbox? How to build it? How to contribute? You come on this forum and ask us a question. So, you can ask a question. But if you want to ask a question, you have to register. Until now, for whatever I did till now, you do not have to log in at all. We do not even want to know who you are, what college you are from, what is your name, what is your email address, what is your password. We do not want to know any of those. But if you want to ask a question, you have to register. Of course, in this case also, we would not know your password because the password is encrypted and kept and only then, you can do. So, let me log in. If my password is correct, so this is fine. We want to save this. Never. We do not want to save my password here. Now, I can select a first category. Let us say Sylab and I can ask this question, question description and submit the question. It goes into the forum. Are people see it? Of course, you could ask questions like, what is a great movie running in Mumbai? Of course, you can ask this question. But then, if you do that, then this forum will be useless. So, I would want you to ask focused questions so that it is not only can we answer your question, somebody else will also answer your question and this will be a useful forum. We would want you to control yourself and ask the right question and we will be able to help you. So, let me go back. So, do you have a question? That is where you have to post. Then, what do we do? Post them on posse forum. Like I showed, only thing is you have to register to post. Please do register. If there are posts, we can come live on. In fact, what we also offered to do is every Tuesday, 3 to 3.30, we offered to come live on Google Hangout. Of course, Google Hangout can accommodate only 25 people at a time. But I do not think there will be more than 25 people because previously, we advertised there were not too many people. So, 25 is a big number. Of course, if there are lots of people, we can come through AVU once again. But I believe it is not required. For example, some 10 people may say, look, I have a question on image processing. So, fine. You come on. You post it on the forum. We will come. Our image processing person will be available and they will answer your questions. So, we have already announced. Google Hangout on Tuesdays, 3 to 3.30 p.m. So, you have specific questions. Please post them now. One of our team members will be there next Tuesday, 3 to 3.30. And where to come? That also we will announce it there as an answer to your forum question. Let me go ahead. And of course, we would also want experts to come and join. Maybe you are an expert in let us say power systems lab. So, and there is a question on power systems. Please come and answer. Be available on Google Hangout and answer your question because this is very important. We want to recognize all people who are good in certain topic. And of course, post questions on other software also. That is what I have written. Unfortunately, I am not able to see this here. So, it does not matter. What I mean is, so remember, Fawcetotin covers lot of other topics, DWC, OpenModelica, OpenForm, Python. You may have question on those. You could post them also. And if there are lot of questions on Python, maybe somebody from the Python team will appear and answer your questions. So, this forum is extremely useful. If we use it nicely, it will be very good. But supposing you ask me a question, is it still raining heavily in Mumbai? Obviously, this is spam. And you do not want to do that. You want to restrict to targeted questions. Then we can really make it useful. And we can, our team can really make itself available to answer all your questions. Remember, now we are talking about the top 1 percent. Top 1 percent. So, you are experts. You will also able to contribute. You will be able to help other people. So, we want to build this as a forum where experts can come also contribute. Of course, there will be some beginners also and they can be helped. Now, how to get started? All this is great. Fantastic. I have never used sila. Can I get started? So, how do you get started? This is the point number 6 in the outline that I presented. So, here is a set of things you need to do. For example, how do you do that? Try the sila TBC for the textbook you are using. That is the easiest. You are a faculty member. You are teaching a course. You have a standard textbook. Its TBC is available. Start with that. You do not even have to do coding. You do not have to know. Just go through it. Sila is so easy to understand. Then what do you do? You modify the code to solve your problems. Learn sila from spoken tutorials. You are running. Then you say, hey, I want to, you know, learn. I want to teach sila. I want to offer sila to my students. Immediately, I get a call. Can you come to this place x, y, z and conduct this course? There are 5000 engineering colleges and many of them want to switch to sila. How many colleges can I go to? How many colleges can we go to? You do not need us actually. That is why we created spoken tutorials. We created spoken tutorials so that you can learn yourself. Spoken tutorial is created for self-learning. So, learn sila from spoken tutorial. I am going to show you where spoken tutorials are. So, let us go back to the website. So, let me come to spoken tutorials. Here it is spoken iPhone tutorial dot org. It is an amazing project. We have a large number of tutorials, lots of topics. You can actually go through this. In case you are not familiar with spoken tutorial, you can actually click this. You will see lots of these. But here the focus is sila. Let us go to sila. Let us choose English. Let us search. And it says there are 25 spoken tutorials. We start out by saying why sila? Installing, of course, you actually know lot more reasons why you should use sila. Because whatever I talk till now is not captured in these spoken tutorials. This is the special talk that I am giving that explains the 65,000 examples. Why sila? Installing, getting started, vector operations, each of them is about 10 minutes long. For example, you can actually click that and you can play that and so on. Welcome to the spoken tutorial on vector operations. So, I am going to pause this. Let me go back. Now, remember the most important thing about spoken tutorials is that it is created for self-learning. That means you can learn yourself. Your students can learn by themselves. You do not need anybody else. You start with textbook companion, you learn all that. Then you say that I want to go next level, come to spoken tutorials, do that. Now, how does one learn this? We use a method called side-by-side learning. Basically, what you will do is you will open the spoken tutorials on one half of the screen. In other half of the screen, you will open the silab software itself. Remember, silab software is open source software. You can download. You can also open it simultaneously. So, let me show you one tutorial called side-by-side learning. It is an important one. This is the method I would want you to follow. If I am not mistaken, it is in something called spoken tutorial technology. So, maybe towards the end, side-by-side method is there. So, let me open that. So, let me play this. I found that people are not following this method exactly. That explains the side-by-side method. So, I created a spoken tutorial to explain what is meant by side-by-side. In this tutorial, let me advance a little bit. Turn in this spoken tutorial. Can hyphen tutorial dot var g? Let us look at silab spoken tutorials. Let me advance a little bit. I have already made it as small as little bit more. In this case, should we maximize the software window? You can see that I have opened the silab software here, but this is the video. You can see that this says it is in English. This is the silab website. This is the video that is playing. Open the video in half the screen. In other half, open silab software. Listen to a command. Pause it. For example, if you play this, you see this button here. See this button? So, this is the video button. You can VCR button. You can stop, play and all that. Listen to a command. Pause that. Try it out. If it works, go to the next command. If not, rewind. Listen to it. Try it again. It will always work because it is created for self-learning. It will always work because it is created for self-learning. So, your students are smart enough to do it by themselves. You do not need me. All the 5000 colleges do not need to call me. You have to pay my airfare and then you have to pay some extra charges. All that is not required. It is too expensive for you to do that. In fact, we are going to make it expensive so that you do not call me. We are going to make it expensive. You do not call me and this is available free of cost for you. So, now, one other thing that I want to show you. We have a great team that will organize sila workshops for you. In fact, let me show you how to access it. See this software training. You are in spoken iPhone tutorial dot var g. It is in our every website. Let me just click that again. See this software training. If you click this, under this, you see this contacts for training. And you have our representatives for all states. So, you can see their names. You can see state, name of the person, email address, phone number and we have covered all the states. What I am going to do is my spoken tutorial team members are here and I am going to pass on the mic. They will just mention the name and their state because we may be running out of time because later on I am going to give the mic also to Shamika and the toolbox team. So, just briefly introduce yourselves and they are all at your service. Yes, Shama, please go ahead. Hello everybody. So, nice to connect with you. I am Shama and I had this training team or look after the training activities nationally. So, I am my mail id and number is also there and you want to get connected with anybody. You can contact me or contact the individuals if you are in that particular state. I am handing over to Hello everybody. My name is Nidhi Soni and I am taking care of Rajasthan state. Thank you. Hi everyone. My name is Varsha Dand and I am handling Uttar Pradesh state. Hello everyone. My name is Sanchita Samant and I am taking care of Andhra Pradesh state. Thank you. Hello. My name is Jesse Veluswamy and I am handling Chhattisgarh, Arunachal Pradesh and Assam. Thank you. Hello everyone. My name is Madhukrti Srivastava. I am taking care of Gujarat, Tripura and Sikkim. Hello everyone. My name is Pooja Singh and I am taking care of Meghalaya and Bihar state. Hello everyone. My name is Daina and I take care of the technical web queries of the team. Thank you. Hello everyone. My name is Ruchi Sharma and I am taking care of Uttarakhand. Thank you. Hello. My name is Swapnilmore and I take care of Nagaland and Jharkhand. Hello. My name is Vidya Kadam and I am handling Maharashtra state. Hello. I am Anushree here and I am taking care of Karnataka state. Thank you. Hello everyone. I am Aatrupti More and I am taking care of West Bengal and Mizoram. Hello everyone. Myself Swati Dongardhiway taking care of Odisha, Goa and Manipur. Thank you. I am Sandra Cruz and I am taking care of Delhi and Pondicherry. Yeah. Hello everyone. I am Mohammad Kasim. I am handling Telangana state. Hi everyone. I am Manita and I am taking care of Himachal Pradesh. Thank you. So, that is the Spokaneutorial team and they are available. So, you want to make it available in your college. They are ready to set it up. By the way, we have already trained 2 lakh students on SILAC. So, you want to see? I will show you our website. I am going to take you to a place called Spokaneutorial.org. We have something called statistics. If you click here, you will see that we have trained close to 40 lakh, 39 lakh actually. And different states you can actually choose, but let us choose SILAB here, filter. You can see that we have trained 2,17,000 students on SILAB in various states and you are welcome to contact our team members. They will be happy to set up this workshop for you and all your students will start using SILAB from the next day. Create textbook companions. How to create textbook companions? Remember, I already showed you in SILAB.in. All the information is there. How to process? How to create? Let me show that for you. In fact, you can do this here. This is the SILAB.in. You can see the textbook companion project. It actually talks about internship, guidelines, honorarium, completed books and so on. It says for more details click here. So, all that information is available here. Contribute to live migration. We would want you to do that. I have already explained how to do that. I am saying that do it in that sequence. Do it in that sequence. Try the SILAB TBC first. Modify it. Use it. Learn SILAB from textbook companion. Use our team. Create textbook companions. Contribute to live migration and going ahead. Now, you want to be a partner. First of all, train your students on SILAB. Then you say, look train the trainers on SILAB. I want to be a partner because I have trained 100 college teachers from various colleges and they are training their people. So, I am one level higher. Answer the questions posed by others on the forum. Remember, we are going to ask questions. You are going to ask questions. We are going to answer. We want experts to answer. So, we will know who is the expert, who is answering these questions. Contribute a function to a SILAB toolbox. Lead the development of a SILAB toolbox. Here, we are leading and you contribute a function. You faculty member contributes, student contributes, becomes an intern or you yourself can spend couple of months at IIT Bombay, whatever it is. Then you say that, hey, I have a great idea. I want to lead the development of a SILAB toolbox. Power sim, for example, or in a power system simulation or whatever it is. So, this is all I wanted to speak. I have taken lot more time. Join the 3 p m meetings on Tuesdays. This is what I have written. Join the 3 p m meetings on Tuesdays. It is not seen for whatever reason. I know that there are lots of questions. I am going to answer some of the questions and I also want to introduce my team before I. So, let me conclude this. Then I am going to give the mic to, in fact, we can do it right now. Can we show Shamika? I want Shamika and Vinita. So, Shamika is the one who leads our toolbox project and in case there is, Shamika has come prepared to give a demonstration of a toolbox. And of course, a toolbox is something niche that may not be of interest to all of you because there are about 2000 people listening and maybe another 2000 people watching it through YouTube. I do not think all 4000 will be interested in a signal processing toolbox. So, we can always set it up. For example, you say that next Tuesday, 3 o'clock, Google Hangout, Shamika is going to describe, give a demonstration of, let us say, image processing toolbox. A lot of people ask for it and we are available. She will definitely come and give a demonstration. She may even be able to give a demonstration of two toolboxes. Although we are saying only half an hour, if a lot of people are there, keep asking questions. She is not going to give, she is not going to leave halfway. She is going to demonstrate, let us say, optimization toolbox, image processing toolbox, let us say, signal processing toolbox, whatever you have a question on. She will do that. But right now, I am going to ask Shamika to say a few words so you know who Shamika is. Hi, everyone. My name is Shamika and I have been part of the SILAP group for the past five years. And currently, I am leading the SILAP toolbox development effort. We have been very happy with the response we have received over ABU as well as YouTube and we have been trying to answer most of the questions. At the moment, we do not have time to demo the toolboxes, but please do get in touch with us over Fawciforums. That is the best way to get in touch with us. Please force your queries on SILAP or do request for YouTube live sessions and we would be more than happy to conduct them. Like Sir said, please ask for such sessions so that we can demo our toolboxes and do go through the links that Sir did show over the past two hours so that you can actually start using these toolboxes and also contribute to these toolboxes. I will just hand over the mic to the rest of the team and they will introduce themselves. Hello, everyone. I am Poonam Borkar and I have joined here as intern and I am working on Power System project. It is coding on SILAP. Thank you. My name is Sharwari Namdar. I am intern here. I am doing the project on the load flow analysis and transient stability by using the SILAP software. Thank you. This is Ashutosh Kumar Bhargav. I am working on Control Toolbox and Identification Toolbox. Hi, my name is Tushar Wang and I am working on Power System Toolbox. I am Siddharth and I am handling the textbook companion project as a reviewer. Hello, everyone. I am Brijesh Gupta and I am working as a research assistant in SILAP. Hi, everyone. My name is Abhinav. I am working as a research assistant in SILAP team. Give it to Vinita. Hi, everyone. I am Vinita and I am working as one of the managers of Fawcay Project and I am taking care of SILAP, basically the textbook companion and the overall website related to SILAP and the whole thing. We are really happy with your response and we will definitely have more sessions like this, but we want you all to come to the weekly meetings which we have every Tuesday. So, we can answer more questions on SILAP and we really look forward to see you on Tuesday. Bye. And we have one more member, Rupak. He will introduce himself. My name is Rupak Rokre. I work at Fawcay and I work for projects such as hardware interfacing with SILAP. So, if you have any questions about how do you interface hardware with SILAP and how do you do data acquisitions with it, you feel free to contact us and please do attend our weekly sessions and you can ask questions. We can discuss a lot of things over these live meetings and I also look after virtual labs. So, if you are interested, you can take it out. Thank you. Okay. So, you saw our team. I want to spend one more minute on what Rupak talked about. Rupak is the last person who talked about hardware interfacing. In fact, he has set up an amazing lab called single board heater system. All kinds of control experiments can be done remotely from your college onto the system that we have at IIT Bombay. You can do open loop experiments, basically you can do all kinds of control experiments using that. And because of lack of time, we will not give a demonstration, but in one of the weekly meetings, I am sure that Rupak can give a demonstration of that, how you can register yourselves, how you can use it for one of your control labs remotely and so on. So, right now we will not spend too much more time on that. Let me get back. Let me complete this. Okay. So, I have come to conclusions. Sylab is a great tool worth thousands of rupees, if not lakhs. You can solve most of your problems using TBC. You can also learn to add new functions. We welcome Sylab experts in training others on Sylab. Join us in this nation building activity. And this project is funded by the National Mission on Education through ICT, NME ICT through the FOSI initiative. And recently, we have also been funded by the Pandit Madan Mohan Malavi on National Mission on Teachers and Teaching. Both have come from MHRD government of India. We are very grateful to them. Remember all the hundred that we have given, 12,000 rupees to a person and then 20 percent increase for AICT approved books. We have done it for, you know, 500 books. Look at the amount involved. Where did this money come from? It has come from MHRD. It has come from taxpayers' money. We are grateful to MHRD for having funded this, but it has come from taxpayers' money. We have to put it to use. We request all of you to use this great facility that we have created with government support. So, with this, I have come to the end of this presentation. I would like to thank you for your patient hearing. Now, in the remaining few minutes, I would like to answer questions if you have any. Remember, if you have questions, a lot of toolbox related questions and so on can be answered through the weekly meeting, but if there are some important questions that I can take them off. One of the things that I want to point out is that Tuesday meeting is not a workshop. If in case you people say, I will come on Tuesday to find out what is siler, sorry, you are in the wrong place. You are in the wrong place. That Tuesday meeting is not for organizing workshop. How to organize workshop? I already introduced my spoken tutorial team members. Please contact them. They will organize workshops for you. Our Tuesday meetings will be to answer advanced questions. You are writing a function, you have difficulty or you want to know about, more about some toolbox or you want to see a demo of a toolbox that our team led by Shamika has created or you have a question on textbook companion, you want to create, you want to add something, you want to talk to Vinitha. So, you can do that or you want to do some lab, remote lab, you want to talk to Rupert. That is fine, but these are demonstrations. Answering your specific, I mean a few questions. This is not to say how to use silo for 1 plus 2. We cannot do that. For that, we have already created spoken tutorials. So, we are talking about next level help because I hear some of you saying, look, I already know how to do this. I want next level help. Come to the forum, post your question and then we will come on Tuesdays at 3 o'clock. We will answer your questions. If there are any questions, I will be happy to. Please go for hand raise in case there are questions. Do you have any questions? For the research purpose, we want to use silab. So, can you guide us with how to use this? Say, for example, we want to get a relationship between independent variable and dependent variables in optimization to get a linear equation or a polynomial equation for the stimulation and prediction of the optimal parameters. So, for that purpose, can we use silab? Yeah, please use the optimization toolbox of silab. It is available. Tools are available there. You can use that. But before that, would you use that silab tool textbook companion? No, sir. So, why not start using it? It is already available. Thank you. Thank you, sir. Yeah, thank you. Sir, I want to know that as a faculty member, apart from your textbook companion, what else we can contribute ourselves for the silab, sir? You can contribute in lab migration. Migrate one of your labs. Sir, can you elaborate a little bit about it, sir? So, I already showed that. Let us go. So, for example, we saw lab migration project. In the lab migration project, you saw completed labs. These are all the things each of them explains a particular lab. Lots of details are there. Now, if you want to contribute, you have to see this procedure. You also want to become part of it. It says procedure. What is the way to do that? It is explained here. For faculty, how do you do that? You have to fill this lab migration proposal given here. Then if you do not have a login account, you have to register there. Remember, these are advanced things. So, you have to register yourself. It explains how to do that. And then procedure is given. Coding guidelines are given. Honorarium is given. Let me make it zoom it so you can actually see what is it coming here. Procedure, coding guidelines, Honorarium, completed labs, labs in progress, download codes, all kinds of things are available under lab migration. So, this is what you have to do. Thank you. And say, suppose if you are going for a scallop, is there any some letter or something like that from your side so that it should be, we can prove it to the university that yes, we can proceed with that one. AACT has already accepted Syler. If you visit AACT website, it actually shows what are the open source alternatives. AACT recommends that already. So, if AACT recommends, then will your university not use it? You have to put it up. Yeah. Okay. Thank you. Thank you. Yeah. RBS. RBS, you have any questions? Yes, sir. Good evening, sir. I would like to ask you, sir, a question. What is the difference between MATLAB and the Sylab? Basically, MATLAB is widely used inside the PSG and research work. So, how we can use Sylab instead of MATLAB? So, whatever you can do using MATLAB, you can do with Sylab. MATLAB costs a lot of money. Sylab is free. Sylab is free. You do not have to pay. MATLAB costs a lot of money. That is the difference. But there will be the difference between tools basically. If we are using the MATLAB tools, then it will provide a lot of facilities to the scholar instead of Sylab. Yeah. Remember the… We are a such type of people. Remember the 65,000 examples that I presented? Sylab code. It is not available in any other software. You want to set a question to your students. For every one of the solved problems in your book, I have it in Sylab. It is not available in any other software. And it is free. You can use it on your mobile phone. You can use it on your tablet. It is free. Remember, academic cost of proprietary software is one percent. Just to give an example, if you say that it costs a lot of money to buy some commercial software and use it in your college, your student tomorrow graduates and goes to industry, he will not have access to it because in industry the cost will be 100 times that. So, what is the point in teaching him on a commercial software that he cannot use outside the college? Yeah. Thank you. So, in case whatever we have done is recorded and it is also available and I would want you to go through this and if there are questions, you can get in touch with us and use the spoken tutorial methodology to train your students in a big way. Number one, come to our Tuesday meetings for advanced level help. So, thanks a lot. Thanks to all of you for joining. Thanks for your interest and goodbye and Jai Hind.
