 Now, the next project under the 4C group is the implementation of virtual lab experiment in Sandeep. So friends, give a huge round of applause for them. Good evening everyone. Yes. Myself, Sudhanshu Dandini and my project name is Sandeep. So let's first discuss about what is Sandeep. It is a free and open source visual programming editor and in this we can create a flow graph by using the blocks and this editor is developed by 4C team at IIT Bombware which is extension of GNU radio and GNU radio is a free and open source software development kit that provides blocks to implement software radios. Sandeep runs on Linux only. The interface is easy and clean. That means we can use drag and drop. It is used to carry out control system experiment and the main advantage of Sandeep in respect of GNU radio is that it supports feedbacks that is not supported by GNU radio and the size of the Sandeep is very, I mean, not too much of high. It is like without dependency it will take only 20 MB and it supports multiple languages like Python, C++, Skylab and GNU octave. So my task is to implement virtual labs experiments into the Sandeep because virtual labs are implemented in LabVIEW but LabVIEW is a proprietary software that requires too much, that is too costly and license for is very expensive. So Sandeep is a solution. So I have performed five experiments. I have successfully like superposition, Thevenin, Northern, Allegiance and Compensations. So let me show it in the Sandeep. This one is the superposition principle. The output of the top block will show the current in the branches. First I remove the emf source in the first circuit and calculate the current in the subbrances like I1 dash, I2 dash and then remove the second emf source and then remove the current and then finally the current comes like the current of three of the branches. Here we can see that the sum total of the current that is I2 and I3 gives the current. I1 dash is the current in the subbrances and for the circuit purpose you can refer to the site IIT Bombay KZ Kharagpur because the experiment that I have implemented available in that site solely. The next experiment I implemented is Allegiance Theorem and according to that Theorem, the power delivered in the circuit, the power is conserved. So the top block will show the power in the circuit and the current in the branches. The power delivered and the power absorbed are approximately same. The error is due to some circuit parameters changes. I mean the power delivered I have calculated by the help of the manual things and power absorbed I have calculated by the help of by calculating the circuit parameters in all the, considering the Ohm's law. So thank you.
