SRMAP Departmental Events

How many of you thought, “It’s just the beginning of the semester, there’s a lot of time to catch up with studies,” and then struggled with the syllabus before the exams? How many of you were frustrated with assignment submissions just because you did not start it on time? How many sleepless nights have you spent before taking the exams because the revision was due? We are sure that you all have experienced some kind of trouble because you put the work on hold. Admittedly, we all have a procrastinator within ourselves. We all love to postpone things a bit, allowing us some free time to enjoy ourselves. However, we often forget that all the work that is being piled up due to our procrastination will come back to us with a bitter consequence.

A student’s life is a time to learn the essential skills that are going to support them in their future professional and personal growth. Doing tasks on time has its own substantial benefits that are not only going to help you in your academic career but also in every sphere of life. Do you find it to be too difficult to learn?

Dr Smita Sharma is the ideal person who can enlighten you on how procrastination affects our thinking and behaviour. She will further guide you with the techniques to defeat it. Dr Smita, as you know, is your counsellor at SRM University-AP, and she will be available in an Interactive session with you on “Overcoming Procrastination!-Doing Vs Delay”. Join the session on March 27, 2021, at 4 pm.

In the next chapter of Departmental Seminars Series, Department of Mathematics, SRM University-AP, Andhra Pradesh welcomes Dr Chittaranjan Mishra, Department of Mathematics, Indian Institute of Technology Ropar, to deliver a lecture on “Fast pricing of multi-asset American options under jump-diffusion models” on March 24, 2021, at 3 pm.

Multi-asset American options are interesting in many ways, e.g., they give the holder the flexibility to exercise at any time up to maturity, allow for risk diversification and for us, these contracts are mathematically challenging to price due to the non-availability of a closed-form formula. When jumps are introduced to model underlying assets, one will be required to solve a partial integro-differential complementary problem (PIDCP) for pricing these contracts. In these cases, we find that computing sufficiently accurate option prices in real-time is extremely difficult. That is because the in hand PIDCP involves a multi-dimensional partial integro-differential equation with a non-local double integral term. Solving these multi-dimensional PIDCP by advanced numerical techniques, such as a customized finite difference method, is very time-consuming, as the corresponding discretization matrices are huge in size. More importantly, the integral approximation matrix is also dense, posing a serious challenge to handle storage memory. Many efficient techniques are proposed primarily to handle the double integral term. However, the required solving time is still not practicable for practitioners.

In our research, we exploit the amazing parallel architecture of modern graphics processing units (GPUs) to solve computationally expensive scientific problems. Nevertheless, resolving the problem at hand by employing a GPU is not straightforward. It requires one to overcome many bottlenecks, such as in. In this work, we have investigated these issues in order to achieve substantial speed-ups compared to a sequential FD implementation.

Mathematics enthusiasts are requested to avail this opportunity to listen to our distinguished speaker on March 24th, at 3 pm.

Department of Mechanical Engineering welcomes Dr Jaganmohan Rao, Divisional Manager, Ashok Leyland, Chennai, on a Webinar to enlighten the students on ” Automotive NVH (Noise, Vibration and Harshness) – Future Challenges”. The webinar is scheduled for March 04, 2021, at 6 pm. In his speech, Dr Rao will concentrate on the Basics of Automotive Noise and Vibration, NVH Development Process in Industry, NVH Tools and Techniques and Vehicle and Systems NVH.

Dr Jaganmohan Rao is an automotive professional with twenty years of vehicle development and testing experience in major automotive companies such as – Ashok Leyland, Cummins, Hero Honda and TVS motor) in India. He has been the Project Manager for many new product developments in Ashok Leyland in the NVH Domain. He further has Six Sigma Green belt and Black Belt certifications. Dr Rao was the TQBM Coordinator for Product development and a key member of Institute and Industry Relation Developments.

Dr Rao has obtained his PhD in Mechanical Engineering from the National Institutes of Technology (NIT), Trichy. He is a veteran in the field of Noise Vibration and Harshness (NVH). Prior to his doctoral studies, Dr Rao did M.S. in Applied Mechanics from the Indian Institute of Technology (IIT), Madras. His bachelor studies in Mechanical Engineering was pursued from Jawaharlal Nehru Technological University, Kakinada, Andra Pradesh. He has published 14 papers in international Journals and Conferences. He is the proud owner of 2 patents in Electric vehicle fan design. As a Research Supervisor, he has guided 10 B.Tech and 2 M.Tech Projects. Dr Rao further owns a first level TRIZ certificate from The International TRIZ Association.

Join the thought-provoking session today to groom yourself for the challenges of tomorrow.

Progressing with the series of Departmental Seminars, Department of Mathematics, SRM University-AP, Andhra Pradesh invites Dr Gaurav Bhatnagar, Visiting Associate Professor, Department of Mathematics, Ashoka University to deliver a lecture titled “The Partition-Frequency Enumeration Matrix” on March 10, 2021, at 3 PM.

The Partition-Frequency Enumeration (PFE) matrix is an infinite upper-triangular number-theoretic matrix that is used to enumerate partition-like objects as an elementary approach. This matrix unifies voluminous results connecting number-theoretic functions to partition-type functions. The calculus is extended to arbitrary generating functions and functions with Weierstrass products. As a by-product, some well-known recurrence relations for many number-theoretic functions are recovered. These include the sum of divisors function, Ramanujan’s $\tau$ function, sums of squares and triangular numbers, and $\zeta(2n)$, where $n$ is a positive integer. As an application, Ramanujan’s famous congruences $p(5n+4)\equiv 0$ (mod $5)$ and $\tau(5n+5)\equiv 0$ (mod $5)$ are embedded into an infinite family of such congruences. During the lecture, Dr Gaurav Bhatnagar will highlight two other congruence results concerning the sum of the divisor function.

SRM University-AP, Andhra Pradesh has collaborated with the Indian Institute of Remote Sensing (IIRS) -Indian Space Research Organization (ISRO)’s outreach programme, enabling the students of SRM University-AP to avail the 74th IIRS outreach programme titled “Satellite based Navigation: A Journey from GPS to Mobile Phone Platform” sponsored by the Indian Space Research Organisation, Department of Space, Government of India. This programme is scheduled for March 1-12, 2021 and will be held from 4 PM till 5.30 PM.

In the modern era, an enormous volume of geo-spatial data is acquired from various sources, which is further processed for various studies on earth’s resources. These geospatial datasets require secondary data in the form of geo-tagged samples, Ground Control Points (GCPs), and ground-based large scale maps, which can be acquired using Global Navigation Satellite System (GNSS) technology. Apart from its applications in precise positioning, GNSS has applications in various areas such as Total Electron Content (TEC) estimation, earthquake studies, atmospheric studies, and mobile Geographic Information System (GIS).

The 74th outreach programme is committed to impart the basic information about the GNSS, followed by the studies carried out in different related areas. At the end of this course, participants will be able to comprehend the use of GNSS receivers with different measurement and positioning techniques as per the application requirement.
