3. Title of the talk:Solving for an equation that doesn’t exist: the generalized Riccati theory
Date: 13-11-2019
Speaker: Dr. Debasattam Pal, Associate Professor, Department of Electrical Engineering, IIT Bombay
Abstract: The importance of the algebraic Riccati equation (ARE) in control and communication engineering cannot be overstated. However, existence of ARE depends crucially on non-singularity of certain parameter matrices – known as the “regularity condition”. It is known that solutions of the ARE are nothing but some kind of (generalized) stored energy within the system, called “storage functions”. Existence of storage functions is a property known as dissipativity. Arguably, dissipativity is a system’s inherent property, and hence, it ought to be independent of whether the system’s parameter matrices are satisfying the regularity condition or not. The question is: if the ARE does not exist, how then do we get its solution – the storage function? In this talk we shall try to investigate this case of “singular” dissipative systems. We shall see how the resolution of this conundrum lies within a generalization of the so called Hamiltonian matrix to a corresponding Hamiltonian system. We shall also see some remarkable consequences of this resolution.

6. Title of the talk:Dynamic Modelling and Optimal Management of Air-traffic over Indian Airspace
Speaker: Prof. Radhakant Padhi, Professor, Dept. of Aerospace Engineering, Indian Institute of Science, Bangalore
Abstract: Rapid growth in the air-traffic over Indian airspace is slowly becoming quite overwhelming for the existing Air Traffic Control (ATC) system to handle. Appropriate safety measures need to be taken to maintain sufficient separation between them at all point of time while maximizing the air traffic volume in the available airspace at all time. Since different aircrafts fly at different speeds, and also cannot hover for buying time for decision making, the problem is substantially complex. This problem is also aggravated in the vicinity of the airports located in metro cities. Since manual monitoring and guiding of all aircrafts 24/7 in real-time is impossible, optimal, intelligent and predictive decision-making technology needs to be developed to automate the process as much as possible. The first step in this direction is to have a reliable air-traffic flow model for all commercial flights, so that the traffic density in future time can be predicted and appropriate decision can be taken well ahead of time. This problem has been well recognized in the USA, and NASA has come up with the Future ATM Concepts Evaluation Tool (FACET) model. Using the FACET model, many interesting and useful research has been and are being carried out in the USA. Similar research is also being carried out in the Europe on the same topic. However, such a dynamic air-traffic model does not exist for Indian airspace and hence there is no activity in India towards it. Therefore, creation of such an extensive dynamic Air Traffic Model for Airspace (ATMA) of India model, which will include both cruising flights en-route as well as flights near the airports, is a bad necessity at this point of time. This model will include kinematics of flight, information from Base of Aircraft Data (BADA) about performance characteristics of aircrafts, Geodesic coordinates of Airports and declared flight schedules of Airlines. After developing the “ATMA of India” model, a variety of intensive research will be carried out such as 4-D trajectory optimization for maximizing the runway capacity, collision free network stability analysis for an airline's intent to introduce new flights, Sense-and-avoid reactive collision avoidance in case of emergencies, Online re-optimization of trajectories in case of bad weather and/or emergencies etc. This talk will give an overview of the overall problem and highlight the recently initiated activities on this topic in Prof. Padhi’s lab.

8. Title of the talk:Machine Learning for Signal Processing, and Vice Versa
Speaker: Prof. S. R. M. Prasanna, Professor in the Dept. of Electrical Engineering, and Dean (Faculty Welfare, Research and Development) at IIT Dharwad
Abstract: Signal processing had its glamorous existence over half a century. With machine learning entering into every field, there is a question about the relevance of signal processing. In this talk, the speaker will argue about the coexistence of both the fields. The main objective of signal processing, at least with respect to pattern recognition is to extract relevant features at reduced data rate. Machine learning helps in extracting features from the raw signals by employing a nonlinear processing. With deep learning becoming the latest trend for machine learning, it is becoming difficult to interpret the features extracted or performance achieved. Exactly at this juncture, signal processing knowledge seems to be the saviour. The recent work using sincnet for speaker recognition demonstrates the usefulness of signal processing knowledge for better interpretability and also improved performance under certain conditions.

Date:2-03-2022, 2:30 PM- 3:30 PM
Speaker: Prof. Vinod Khadkikar, Professor, EE Department, IIT Bombay
Abstract: The growth of local renewable energy sources and heavy loads in power distribution networks, such as the increasing electric vehicles charging stations, causes several issues with a direct impact on the stability of the electrical grid. An attempt to overcome such issues is the microgrid concept, which has the grid structured into local sub-grids that manage their power and energy balancing. A microgrid may operate connected or disconnected from the main grid, being dynamically necessary to guarantee a power balancing between local loads and sources. Furthermore, as several power units are connected to the same microgrid, equity is also required in terms of active, reactive and harmonic power sharing. In today’s talk we will explore a scenario of an island operation of a micro grid with multiple sources, including battery storage systems and sharing power with multiple loads including electric vehicle chargers. A local control solution for a stable operation of the micro grid in terms of both power balancing and power sharing will be discussed.

13. Title of the talk:Some properties of integer numbers
Date:28-03-2022, 4:00 PM- 5:00 PM
Speaker: T.S. Rathore, Department of Electrical Engineering, IIT Bombay
Abstract: The lecture will discuss the properties of integer numbers in two parts. The first part will deal with the extension of Kaprekar’s operation. It examines what happens when the iterative operations given by
(?1?2?3 … ??−1 ??) − (????−1 … ?3?2?1)
are carried out. It is shown that the process eventually ends up in a flow diagram: a straight line and a circle. The circle may have either 2 or 5 numbers on it. The second part deals with how to arrange integer numbers 1 to n such that the sum of two adjacent numbers is a perfect square. The following are the important findings:
1. When n is less than 31, there is no closed loop (necklace). When n is 15, 16, 17 there is a single open loop (chain) which contains all the numbers 1 to n. When n is 20, there are two necklaces and two chains connected together. Number 31 is different than all the numbers less than this in the sense that it has more than 2 possible options for each number and needs special treatment.
2. When n is 32 and 33, there is one and only one possible necklace.
3. When n is above 33, all the numbers have more than one necklaces possible. The number of necklaces increases rapidly as n increases above 43. For example, for n = 35, there are 57 possible necklaces.
The lecture will end up with some expected applications of the chains and necklaces.

16. Title of the talk:Scattering Media: useful tools and challenging obstacles for optical imaging
Speaker: Prof. Steve Cuong Dang,
Abstract: In the interactive talk, Prof. Subrat spoke about pre and post covid life and managing time in most efficient and accurate way.
Biography of the speaker: The scattering media, such as frosted glass or biological tissue and human skin, seems only to diffuse light, creating random speckles and deteriorating our visual ability as well as imaging capability. Here, we demonstrate that scattering media not only help us take photos but also do spectral filtering simultaneously. More interestingly, a single piece of optical diffuser can work as multiple lenses and multiple filters for a single-shot multi view or multispectral camera[1]. Besides the ground glass optical diffusers, i.e., the static scattering media, that can be pre-characterized and utilized, there are various biological tissues that are dynamic optical diffusers and cannot be characterized, creating enormous challenges to realize the object hidden behind even at low resolution. Our group pioneered non-invasive super-resolution imaging through scattering media. In the talk, I will discuss stochastic optical scattering localization imaging (SOSLI)[2] and non-invasive super-resolution speckle fluctuation imaging (NISSFI)[3], our two techniques to take super-resolution images through scattering media non-invasively. We simply use a camera (without any lens) to capture multiple speckle patterns created by stochastic emitters in the object. Then, our computational approach with a phase retrieval algorithm, point-spreading function (PSF) estimation, deconvolution, localization, and high-order cumulants, can sharply retrieve the object hidden behind scattering media. Our super-resolution techniques break the diffraction limit to realize nanometer-scale objects from their speckle patterns through dynamic scattering media. Our results present a new and practical approach towards sub-diffraction limited biological imaging with superior clarity.

17. Title of the talk:SInverse Problems with Nonnegative and Sparse Solutions: Algorithms and Application to Phase Retrieve Problem
Speaker: Prof. Pham Quy Muoi,
Abstract: In this talk, I present a gradient-type and semi-smooth Newton method to minimize the regularized inverse problems for nonnegative and sparse solutions. Using a special penalty functional, regularized minimization problems get nonnegative and sparse minimizers, and then the algorithms are applied to solve the regularized minimizer problems. The strong convergence of the gradient-type method and the local superlinear convergence of the semi-smooth Newton method is proved. Then, The algorithms are used to solve the phase retrieval problem. The efficiency of the algorithms is illustrated through a numerical example.

18. Title of the talk:: The Case for carbon as driver for Next generation device for High sensitivity sensing and Energy storage
Speaker: Prof. Samuel Kinde Kassegne,
Abstract: The broad areas of carbon, particularly in glassy carbon and graphene, continue to experience renewed and increasing research interest. Their established biocompatibility, high signal-to-noise ratio, high charge storage capacity, resistance to corrosion, and MRI-compatibility have further enabled carbon materials to emerge as a compelling material for biosensing and implantable probes. But still, could their mechanical, electrical, and electrochemical properties be improved even more for an increasing array of application areas? In this talk, we present recent experimental progress made in establishing carbon as a versatile electrode material in the broad areas of BCI (brain computer interface) and bioelectronics and also explore the opportunities available in further extending the use of carbon in next generation bio-sensing and energy storage systems. In specific terms, we will present a computational framework built around a reactive molecular dynamics simulation using bond-order based reactive force field formulations. This framework is used for modelling the synthesis process and investigating in detail (i) the reaction pathways that give rise to intermediate and final species (ii) the intermediate and final stages of carbonization with particular focus on nanostructures and (iii) formation of functional groups and the processes and parameters that drive their evolution. Through a combination of experimental work, computational framework, and comprehensive morphological and surface material characterizations, we present evidence that demonstrate that carbon is increasingly becoming a material of interest for a wider adoption in such applications as bioelectronic systems, BCI, and implanted glucose monitors in a closed loop manner where electrical and electrochemical recordings are needed. Further, we demonstrate that there is plenty of room for exploration and discovery of hybrid carbon materials, particularly from allotropes of carbon in high-temperature environment, where new research possibilities exist in experimental and modeling approaches that contribute to bridging the current gaps in isolated research in each of the carbon allotropes.
