Good day, Dr. S. Sridevi Sathya Priya. I'm Arjun. I've had a look through your background and your professional record. I'm interested in hearing more about your work and how you see yourself fitting in here with our faculty. Ready to start?

Yes, I'm ready too.

Slide.

Let us start. Dr. Priya, could you walk me through your understanding of image processing and its applications in modern electronics or communication systems?

Yes, Sir. So I'm Doctor Sridevi Satyapriya, working as Associate Professor in.

SKCT college and I am very much interested in doing research and I have.

More than 50 publications in my Scopus and then my work includes.

Implementation of cryptographical algorithms on FPGA then.

I have a, uh, uh, worked in some algorithms and also I for my cryptography work, I have taken the image as a input, uh, that is, uh, biometric image as a input. And I have processed those images, generated the cryptographic key, and I have given those key as the input for my cryptographic algorithm. And I have improved the security by using the biometric.

Biometric data. So this is a regarding myself and my research work.

And.

Regarding the second question which you have asked, the importance of the image processing. So nowadays in many of the places they we are using CCTV cameras and also for in many of the applications we are giving image as a input. So it is very important to process those images. So it is very important.

Engineering student we should have some knowledge in the image processing field. So this is my perspective is that. Thank you.

As a.

Thank you, Dr. Priya. You mentioned implementing cryptographical algorithms using biometric data. Could you elaborate on how you addressed key challenges such as noise in biometric images or variability in image data during processing?

Yes Sir. So I didn't much concentrate on this biometric key. This is part of my work. So as a part of my work I have taken the biometric image as an input. So while selecting the images, what I have faced as challenge means the getting the data and the false rejection rates and false accepting rates. So it is very important to.

Then there are possibility of getting false rejections and also false acceptance which may lead to totally the failure in the cryptographic algorithm. So that is what I faced as a.

Process the image properly. So if you are not extracting the features properly.

A challenge and also doing the process of images. The images are taken as an input and I have extracted the features. The features are extracted from the images and then the images are processed and the processed from the processed images.

The binary bits are generated. Since I have used AES algorithm it needs 128 bit data and also the 128 bit key. So for generating this 128 bit key I have gone for the biometric data. So this 128 bit key is generated from a biometric data. So for this I have gone for the feature extraction and the. And I have processed the features and I have generated the.

Uh, 128 but key.

Yes, Sir. Thank you.

Let us now move to the next skill area. Can you explain any key concepts or methodologies you have utilized in embedded systems and communications in your academic or research pursuits?

Sir.

I have uh, my actually the my research area is umm.

VLSI So since I'm using a BLSI the end application that is integration of the ICS are going to be the embedded. So I have gone for some applications like I have guided some projects and also I have done some projects in embedded so like we have.

Uh, used some of the we have implemented some of the, uh, home appliances as a mini project work and.

And also regarding communication, so actually my area is VLSI and also the embedded. So communication as I have studied UG as I have selected my major as electronics and communication, I have studied some of the communication papers and also.

During my work, I have also guided some of the communication projects like designing antennas.

Particularly in guiding those projects, I have used 1D, the VLSI part of this site. So this is my exposure regarding the embedded and the VLSI applications, sorry, communication applications. Thank you, Sir.

And those things I have guided and in.

Thank you, Dr. Priya. Since you mentioned guiding projects in embedded systems and communication, could you specify one challenging student project in these domains? What specific guidance did you provide to help overcome obstacles?

Yes Sir, so I have guided one now UG project which students have done the image processing applications and from the.

From the cloud they are storing while frying the tea leaves they are taking the instant images and it will be stored in the cloud. So the manager who is sitting also can see the quality of the lead which is being tried and also the workers those who are working also can check it lively and those who are doing a quality check remotely they can also check.

So during that period we have faced some challenges in processing the datas and capturing the images. So in that way I have given them the advice to go for some. Databases and initially they worked with the databases and also we have communicated with the some of the T producer companies and they have visited some companies in the Kunoor and they have gone for some live exposure.

Then out of that they got some exposure and it was very much helpful for them to do the implementation lively. So this is what I have done. I have guided and this is my part during the project and also while writing the image processing. While processing, extracting the features they got some doubts what are the features will be unique and how to extract it. And we we also discussed with the experts and they have extracted the.

To check to confirm that the leave tea leaves are fried properly.

Features so that.

It's the thank you.

Thank you, Dr. Priya. Moving to the next area, can you explain your approach to teaching theory and laboratory courses? Specifically, how do you ensure students grasp both the foundational principles and practical applications effectively?

Sir, as a part of my teaching job, it is very.

Important to check the feedback of the students. So then and there they'll be, I will be collecting the feedback from these students. So since it is a traditional method, it will help us in a good way. So to improve my teaching strategy and also coming to the modern tools to check these students.

Understanding capacity. Normally each and every class will be giving some.

Quizzes that is MCQ questions. It will be posted in the Google Classroom and also some of the LMS tools.

So maybe it is a simple question but it will check the students addictiveness and also how far the student has understand the basic concepts which we have delivered in that particular class. And also at the end of each and every course I normally ask these students to do some mini projects.

Which will be the application oriented projects. So maybe it is a simple project but it will give some skills and also I can understand how far the students got the understanding in that particular subject. So this is what normally I follow and also for each and every internal exams that is.

CA exams, uh, we will be doing some umm, analysis of the Marks and depending upon the analysis, I conduct the coaching classes for the students, those who got.

Below the expected Marks and also we will give some advanced trainings to the students those who got above expected marks. So the this will improve the strategy, this will improve these students, those who are in below expected marks will improve their performance and already if they are top performance. Like GATE questions and also some of the competitive exams questions will be discussed.

In teaching learning.

Thank you, Sir.

Thank you for sharing that detailed approach, Dr. Priya. Let's delve into another crucial area. How do you approach student evaluations and exam duties to ensure fairness and maintain academic integrity?

Is it exam point of view Sir?

Is this question is regarding exam point of view?

How far I'll be far in correcting.

Papers. So regarding this, normally I will prepare a key if it is a exam point of view. Each and after completing each and every exam, the question papers will be checked and after checking the question paper immediately the feedback will be given to the COES and.

Help me to check all the papers properly. If as per the key all the questions will be corrected and the marks will be given. So after giving marks then and there the Co will be calculated. That is course outcome will be evaluated. For each question there will be allotted course outcome. So the course outcome evaluation will be done then and there after every exams and.

The immediately after receiving my question paper after the exam, I will prepare a key. So this will.

As per the.

Co evaluations, uh, the next step will be done. So if they have, uh, most of the students have achieved a particular, uh, SIBO, uh, which means that, uh, in the particular SIBO, the students have performed well. And if suppose the, the in the particular Co, if they got less marks, lesser than the expected percentage, then there should be some improvement done on.

Projects and by giving some extra classes and also the by conducting some practice test, we can, we can do the improvement in that particular CBO. So this is what my strategy to maintain the fairness and the evaluation. So the keys will be here.

Thank

Particular course outcome, so by giving some assignments and by giving some.

Keys will be prepared and as per the key, the evaluation will be done and we will go for the scrutiny process to check my fairness.

Thank you, Dr. Priya. Moving forward, could you explain your approach to guiding student projects and research? Specifically, how do you ensure students gain both academic rigor and practical relevance in their work?

Yes. So regarding project.

So normally the 0 tribute during before 0TH review once the student is allotted we will have one meeting and during that meeting we will be discussing our research areas. So while discussing the research areas we will discuss about the key thrust areas. So what are the thrust areas we have and what are the skills they have learned and what is my expertise. So we will be selecting the.

So I will suggest the specific topic. So before suggesting the suggestion of the specific topic, we will do some literature review. So I'll be helping these students to do the literatures properly. They'll be collecting some literature papers and depending upon the literature paper analysis, we will come to the conclusion and we will be.

Topic. Which will match all these areas and once the topic is decided.

Doing some inferences out of the literature review and with the inferences we again we will have some meetings. What is the inference? What is the? What challenges they faced while doing the. Previous work, so we will try to meet those challenges. So depending upon all these discussions, they'll be selecting the project title. So once the project title is.

Done. Then we will have one review. So during review I'll be sitting with them and they'll be answering the students will be answering all the questions. If they are not able to answer or if they are unknown all those things, then I'll note it down and after coming back to work and we again we'll have one meeting. So whatever in the. Review project review they have raised as a query.

Those queries will be met first, then we will try to answer all those questions which we were not able to answer then. And we will go for the ones our literature is correct and our title is as per the thrust area. Then we will proceed further and in the further process we will be doing the discussing the methodology, how to implement that particular research work and what are the components required and what are the challenges will be faced. So in the initial process depending upon the methodology once the methodology is decided.

Depending upon the methodology we will go for the implementation process and after implementation process will be trying to get the results. So once we are getting the results then we will do the analysis work. So after analysis.

If the results are correct and after analysis, if you are getting any improvement, then we will go further. So if there are no improvements or if it is not expected one, then we will go back to design and we will try to improve.

Our performance or or.

We will make our work as a efficient work and once we are getting expected performance then we will proceed further. We'll be comparing our work with the existing work which is literature. Comparative work will be done then we will go for the further process like either depending upon the project either we will end up with the.

Uh, patent or we will go for the publications like uh, journal publication or the conference publication or I will suggest these students to participate in any of the contests like hackathon idea thought. So all these will be taken as a outcome. So once the outcome is over, then we will be discussing about the future scopes to do or to do the.

Advanced work or continuation of this work?

Thank you, Sir.

Thank you.

Yes, Sir.

Could you describe your communication style and approach to structuring your teaching? How do you ensure clarity and engagement during your lectures?

Yes, so in.

Current uh scenario, the students understanding or students attention uh, span will be uh one to seven minutes, so maximum 7 minutes I'll be delivering the lectures and after 7 minutes.

I'll engage these students to do some activities like I'll give some questions and I'll try to answer all those questions as a tutorial and three minutes I'll be engaging with some other works.

Like group activities and I'll be cracking some.

Quizzes and they'll be cracking and we'll be discussing the current.

Current trends in the technology. So every 7 minutes I'll have on three minutes break, which is not a traditional break. So it is a kind of break which is aligned with the subject. And by the end of each and every class I used to.

Get the feedback in the form of quizzes and also the problems. Normally I give if it is analytical paper. If it is a theory paper, we used to conduct the I used to conduct the quizzes and after before each and every internal exams. Normally I asked to get the feedback from these students so that I can improve my teaching skills. So if I am fast then I'll take the Class A little slow.

And also.

If there are any shortcomings, I'll try to overcome those shortcomings which is mentioned by these students. So this is what normally I use as a strategy for improving my teaching skills.

Thank you, Dr. Priya. Next, I would like to understand your perspective regarding research publications. Could you highlight some of the key research areas you've published in, and how your work contributes to the academic community?

So I have published 15 Scopus journals and out of which I normally consider my work that is analog integrated circuit work as my privilege. So because I have implemented the S box and I have done a lot of research in S box.

Being a VLSI student, uh, I have implemented the S box in the FPGA and I have published the I got a efficient FPGA S box architecture, so that I have implemented in the FPGA that you are using that efficient architecture. I have implemented the advanced encryption standard algorithm on the FPGA and also I have.

Uh, UH-35 plus conference publications and five book chapters available. So most of my publications are later to BLSI. It is FPGA implementation in that I have gone for a cryptographic.

Cryptographic algorithm implementations. So this is my. This is regarding my research work.

Understood, Dr. Priya. Research in VLSI and cryptography requires precision and rigor. Could you elaborate on how your work in FPGA and S-box architecture has been applied practically or how it aims to address specific challenges in the field?

Also submitted some of the projects that is funded projects to the agencies DRDO so in currently.

Our major challenge which is faced by our defense system is they are using some drones. In the drones they are capturing images and they are transferring the images to the.

Officials through the drones, so there are some.

Challenges in doing the encryption process. Since it is used for defense application, the encryption and decryption plays an important role. So after capturing images. So if the FPGA is used then we can go for fast, efficient and also low cost drones. So that is why I have integrated these efficient. Areas algorithm in the drones. That is what I have considered as a practical part.

So we have also submitted 1 project in Dr. depot regarding this.

Thank you, Dr. Priya, for sharing those insights. Lastly, let's discuss your experience with industry projects or consultancy. Could you detail any major project or consultancy work you have undertaken? What was your role, and how did it align with your academic expertise?

Yes, Sir. So regarding the industry projects, I was trying to do the industry projects. So I have discussed with the.

Companies. Few of the companies they are working in analog circuits. Since my workers are digital circuits, I'm looking for a digital implementation and also I have done some.

I have gone for some training in the TESOL systems and for the TESOL students. I have given some Verilog HTL trainings and also I have given some verilog training programs. I have contacted some training programs for students.

To improve their programming skills in Verilog HTL. So as a part of this industry project, I conducted the training programs to improve their programming skills in Verilog HTL.

Professor, to start, could you describe a particular course you find especially rewarding to teach and why?

Please repeat once.

Of course, Professor. Could you describe a particular course you find especially rewarding to teach and why?

Specially regarding to teach so normally being away.

Is there? Is there?

Professor, could you clarify your thoughts? Are you referring to a particular teaching experience or course? I'd like to understand better.

So you want me to teach a particular subject?

So may I know?

Yes, Sir. You want me to teach a course or?

Yes. So yes, Sir.

Shall I go for a teaching?

Issa.

Listen.

Yes, Professor?

Yes, Sir. So being a VLSI student, I'm very interested in teaching digital electronics. So in the digital electronics, normally I take this PLDS that is programmable logic devices as a interesting topic. So in the programmable logic devices, we will have a fixed architecture. So in the fixed architecture you can implement. Any circuit in this fixed architecture. So these PLDS are normally divided into 3 different types.

That is PALPLA and Pro. So in this pixter architectures or implemented using the and array and our array. So our array is the output array considered as output array and and array is considered as a input array. So initially these programmable logic devices are very much useful for developing the prototypes. So before going for the FPGA kind of complex implementations. For checking your projects you can go for the.

PLDS. So PLDS again, you'll have CPLDS and SPLDS. That is complex programmable logic devices and simple programmable logic devices. So using these devices you can implement any complex, any circuit.

Maybe the combinational and sequential circuits, so complex programmable logic devices and in this it is a it is also like the FPGA so simple programmable logic devices. If you are looking for a prototype implementation then it is very well suitable for the applications for prototype development applications. So you can check your projects and you can also come to conclusion whether you can go further for this. Implementation.

So the PLDS are divided into 3 different category PAL, PLA and PRO. So PAL is programmable array logic and PLA is programmable logic array and promise programmable read only memory. So if there are three categories then the next question will be what are the difference between these three categories? Why we are dividing the PLD into three different categories so? PAL, as I said earlier.

The PLD has a fixed architecture where the input arrays are and arrays and the output arrays are or arrays. So depending upon this AND array and or array we can divide this PLD into three different categories. If the and array is fixed and our array is programmable then it is prone that is programmable read only memory and if and array is programmable and our array is fixed then it is called.

Programmable array logic. If both are programmable, then it is a programmable logic array. So these are the major difference between your Chrome PAL and PLA.

Yes, Sir. Shall I proceed further?

Certainly, Professor. If you wish, you can now elaborate on how you connect this topic to your research or how these concepts align with practical applications for teaching.

Yes Sir. So for programming these.

Programmable logic devices. So again we have to go for programming concepts like Verilogue, HTL and VHDLS. So once it is working you're if you're theoretically if the programming logic is working then you can go further like FPGA implementations. So initially we are checking here whether it is working properly or not then we will go further to the implementation of FPGA. So in this.

Implementation of FPGA, normally we will be writing the quotes. So for writing codes either we will go for a text entry or a schematic entry. So schematic entry you can go. For the tools like Cadence and many other synopsis entry tools you can go. And for text entry you can use any tools like Vivado which supports your.
