Thesis Title: Acoustic-Articulatory Mapping: Analysis and Improvements with Neural Network Learning Paradigms Abstract:  Human speech is one of many acoustic signals we perceive, which carries linguistic and paralinguistic (e.g: speaker identity, emotional state) information. Speech acoustics are produced as a result of different temporally overlapping gestures of speech articulators (such as lips, tongue tip, tongue […]

Title: Sustainability through High Voltage Engineering and Research Abstract : Through this talk, we will take a glance at applications of high voltage engineering in three different sustainable technologies. (a) Direct application of high voltage and pulsed power will be shown for economical generation of nanoparticles (NPs) through wire explosion process (WEP). Control of NPs […]

Thesis Title: Analysis and Enhancement of Stability of Power Systems with Utility-scale Photovoltaic Power Plants Guide: Dr. Sarasij Das Abstract: Owing to the negative impact of carbon emissions on the environment, power systems are experiencing a paradigm shift in power generation. The fossil fuel-based generators that utilize synchronous machines are increasingly being replaced by the […]
