Time
16:00
- Presenter:
  Ali Asger Khattab (MTech-I, EE3) (NCPRE Module Lab)
- Venue: GG 103
- Abstract / Poster:
  Measurement is fundamental to the growth and application of science. From the cutting of stone blocks to build pyramids and the timing of eclipses to inaugurate religious ceremonies to the counting of blood cells and the determination of the shape of the earth from satellite orbits, the methods, and techniques of measurement have been extended and improved and our dependence on their reliability has increased. Hence, estimating measurement uncertainty is important. Many people are daunted by the subject of measurement uncertainty. It is a subject that is widely misunderstood, from the factory floor to the highest academic circles. It is a complicated subject and still evolving. After listening to the talk, you will be able to estimate measurement uncertainty in your experiments correctly and easily.

Caching in Information Centric Network (ICN)
Fri

5

Apr

Time
16:30
- Presenter:
  R Sri Prakash (Ph.D, EE1)
- Venue: GG 303
- Abstract / Poster:
  Motivated by applications like Information Centric Networking (ICN) for the Internet of Things (IoT), the talk is about the characterization of the fundamental limit on the performance of caching policies for transient data and characterization of the performance of traditional caching policies like LRU, FIFO. It includes a discussion of caching policies for the setting where the data being cached is heterogeneous in nature. This heterogeneity is in two aspects, namely, the lifetime of the data and the size of the data. The speaker also proposes a caching policy which divides the cache into sub-caches, such that each sub-cache is reserved for data of a specific size and lifetime.

Overview of Benefits and Challenges in Control of Futuristic Power Grids
Wed

Mar

Time
16:00
- Presenter:
  Mr. Kaustav Dey (Ph.D., EE3)
- Venue: EEG 103
- Abstract / Poster:
  Conventional power systems are undergoing massive changes due to the recent emergence of (a) power electronic devices, (b) communication technologies, (c) synchronized phasor measurements. While the introduction of these devices has been intended to improve the system performance, the implementation of these control strategies provides newer challenges and insights. Can renewables provide us better control of the grid? Are there any challenges? Do larger grids provide the solution to the applicability of better control strategies? We shall discuss some interesting aspects of modern grids - benefits and challenges of operation of larger grids with renewable sources and controllable power injection devices.

The role of culture in shaping scientific concepts
Wed

20

Mar

Time
16:30
- Presenter:
  Prof. K Ramasubramanian, HSS Department
- Venue: GG Conference
- Abstract / Poster:
  Over several millennia different "scientific" and "metaphysical" traditions have been pondering over the nature of the physical world, the purpose of its creation, the role of human being in it, the nature of ultimate reality, and so on. The scientists and philosophers belonging to these traditions have introduced a variety of concepts and theories in order to explain the phenomena observed by them. As these practitioners of science are indeed a part of society and do not study the phenomena in isolation, the various ideas, and concepts that are already prevalent in the society seem to have had a discernible influence on their thought process. This becomes evident when we look at the theories that have been put forth in the cultural background in which they emerged. This difference in approach, which seems to been substantially influenced by the culture, has a bearing not only in advancing a theory or a model but also in accepting other theories that have been advanced in order to explain the same phenomenon. By taking specific examples from different disciplines, we will try to highlight some of these aspects during our lecture.

  Amit More, Research Scholar, Vision & Image Processing Lab
- Venue: GG conference
- Abstract / Poster:
  Have you ever wondered why your phone is called a smart-phone? It's the array of different sensors in your phone, like GPS, compass, gyroscope and many others, that makes your phone a smart-phone. In this talk, I'll discuss how can you use the data from these sensors in the smart-phones to process crowd-sourced videos in a totally different way.

Aerostats for Last Mile Communication in a post-disaster scenario
Wed

23

Jan

Time
14:30
- Presenter:
  Prof. Rajkumar S. Pant (Aerospace Engineering Department)
- Venue: GG-303
- Abstract / Poster:
  The first thing that breaks down in a natural disaster situation (such as earthquake, cyclone, or tsunami) is the communication system based on towers or other terrestrial assets. It takes a lot of time to re-establish this communication network, which seriously hampers the post-disaster rescue operations. Many solutions have been proposed for providing communications in such a scenario, such as satellite phones, but they are very expensive, and not so easy to deploy. Once such a solution being proposed is to set up a relocatable height adjustable network using a tethered aerostat system. An Aerostat is an aerodynamically shaped tethered balloon which can act as a long endurance aerial platform to mount a variety of payloads. This talk will describe the results of a recently completed project involving design, fabrication and field testing of a proof-of-concept of an aerostat-based system for providing last-mile communication in a post-disaster scenario. Short video clips of two field trials carried out recently to establish the efficacy of this system will be shown, and the results of the communications trials will be shared.

Time
15:00
- Presenter:
  Vijay A., Reserch Scholar, WiNet Lab
- Venue: GG-302
- Abstract / Poster:
  Did you know that air pollution in India is estimated to kill 1.5 million people every year; it is the fifth largest killer in India. About 91% of the world's population lives in places where the air quality exceeds WHO limits. Is there an engineering solution that will save the world? In this talk, I will speak about signal processing approaches to analyze air pollution using data collected from IoT sensors. In particular, the talk will emphasize on emerging topics such graph signal processing, mobile sampling and model/data driven quantization.

Impact Ionization based SOI Neuron
Wed

Sep

Time
17:00
- Presenter:
  Tanmay Chavan, Neuromorphic Computing Group
- Venue: GG-Conference Room
- Abstract / Poster:
  The human brain is one of the most complex systems known to man. Brain-inspired computing promises an extremely energy and area efficient solution to complex cognitive tasks like learning and recognition. Neurons and synapses are integral components of the brain thus, designing compact energy efficient electronic analogs to neurons and synapses are critical. To this end, our group has experimentally demonstrated a compact conventional 3-terminal partially depleted (PD) SOI-MOSFET based Leaky-Integrate & Fire neuron. Impact ionization induced floating body effect in SOI-MOSFET is used to achieve excellent improvement in area and power compared to conventional analog circuit implementations. Overall, conventional PD-SOI-CMOS technology enables very-large-scale-integration (VLSI) which is essential for biology scale (~ 10^11 neuron based) large neural networks.

Bearing-only formation control over directed cycle graphs
Wed

5

Sep

Time
16:00
- Presenter:
  Prof. Dwaipayan Mukherjee
- Venue: GG-303
- Abstract / Poster:
  This talk will discuss a bearing-only formation control problem for a group of single integrator agents over a directed cycle sensing topology. In two-dimensional space, a necessary and sufficient condition for the feasibility of a set of desired bearing vectors will be presented. Then we shall look at a proposed bearing-only control law for every agent and prove that the formation asymptotically converges to a desired one, specified by a set of feasible desired bearing vectors. Subsequently, analyses of the equilibrium formations in a plane, for a three-agent system as well as an n (>3)-agent system, will follow. Finally, the theoretical analysis on a directed triangle in a plane will be extended to the three-dimensional space and the talk will conclude with some simulations that validate the theoretical results.
