Processing and Analysis of Neonatal and Adult Retinal Images

July 12, 2019 @ 4:00 pm - 5:00 pm
ESB 234

Date:  12.07.2019 Time:   4:00 pm Venue:   ESB 234 Speaker: Sharath M S (EE15S050) Guide:  Mohanasankar Sivaprakasam Co-guide: Kaushik Mitra   ABSTRACT Manual screening of retinal diseases at a very large scale is a challenging task and is aggravated by the lack of availability of ophthalmology experts. This necessitates the need for computer-aided diagnosis (CAD), and in our work, we propose novel methods for retinal image processing and analysis for the cases of neonates and adults. Specifically, we address two retinal…

Minimalist Hand Gesture Recognition using Deep Root Nodal Architecture

July 19, 2019 @ 2:00 pm - 3:00 pm
ESB – 244

Date       : 19.07.2019 Time      : 2.00 PM Venue    : ESB 244 Speaker : Renju P B (EE15S046) Guide    : Dr Kaushik Mitra   Abstract Existing methodologies for hand gesture recognition use a large amount of training data to optimize the parameters of a predefined architecture for improved accuracy. However such techniques are not suitable for real-life applications where the number of training samples for custom gestures are minimal. We propose a novel supervised…

Compact Diffractive Elements for the generation and study of Orbital Angular Momentum beams through scattering media

July 22, 2019 @ 4:00 pm - 5:00 pm
ESB – 244

Speaker: Sruthy J L(EE16S021) Date      : July 22, 2019 (Monday) Time     : 4.00 PM Venue   : ESB 244, Seminar hall Guide    : Dr. Shanti Bhattacharya   Abstract Structured light refers to optical beams with modulated amplitude, phase or polarization. A Gaussian beam generated by a laser source can be structured to have helical wavefront by inducing a phase modulation of the form = , is the azimuthal phase angle,l is an integer. Such beams carry orbital angular momentum (OAM) with…

An Improved Four-Mode Control (IFMC) scheme for H-bridge buck-boost converter

August 13, 2019 @ 4:00 pm - 5:00 pm
ESB – 244

Date:  13/08/2019 Time:  4 P.M Venue:  ESB 244 Speaker:  Akhilesh K (EE17S023) Guide:  Dr. Lakshminarasamma N   ABSTRACT   The H-bridge buck-boost converter shows better efficiency compared to all other buck-boost converter variants due to the ability to work in buck and boost modes. The existence of dead-zone in voltage gain during mode transition due to the maximum and minimum duty limitations results in instability and oscillations in output voltage. This dead-zone is eliminated by overlapping the buck and boost…

August 16, 2019 @ 3:00 pm - 4:00 pm

Date: 16.08.2019 Time: 3 PM Venue: ESB 246C Speaker: Bheemavarapu Lalitha Pratyusha (EE16S005) Guide: Dr. Mohanasankar Sivaprakasam GTC Members : Dr. Sridharan K (Chairperson) Dr. Arun Pachai Kannu (M) Dr. Ramasubba Reddy (AM)   Abstract: The early diagnosis of abnormal medical conditions is extremely important for carrying out prompt and suitable treatment procedures. Especially in low-income group countries, there is a high need for the development of diagnostic technologies that are easily accessible to individuals. The point-of-care diagnostic technology (POC) plays…

Backpressure Based Traffic Signal Control

August 19, 2019 @ 3:20 pm - 4:30 pm
ESB – 244

Date: 19.08.2019 (Monday) Time: 3.20 p.m. Venue: ESB 244 Scholar: Konnur Sneha Basavaraj (EE15S034) Guide: Dr. Krishna Jagannathan Co-Guide: Gaurav Raina   Abstract: Road traffic congestion is a major problem in cities today. There is a need to devise intelligent traffic signal control policies to handle the growing traffic scenario. In this work, we propose intelligent signal control policies for road transportation networks that increase network throughput and reduce delay. The signal control policies need to be scalable for large…

Study of hierarchical decision making in linear quadratic difference games with constraints.

October 21, 2019 @ 3:00 pm - 4:00 pm
ESB – 244, Electrical Engineering, IITM

Date: 21/10/2019 Time: 3 P.M. Venue: ESB244 Speaker: Subhajit Mondal (EE16S073) Guide: Dr. Puduru Viswanadha Reddy   GTC Members:   Dr. Sridharan K (Chairman) Dr. Ramkrishna Pasumarthy (Member) Dr. Nirav Pravinbhai Bhatt (Member)       Abstract   Stackelberg solution concept was proposed by H. von Stackelberg for modeling competition among rational agents. In the control theory context, hierarchical decision making problems can be modeled using this concept. Here, hierarchy implies that one player, called as a leader, has the…
