Analog integrated circuit design using GaAs C-HFETs

Creator:: Gupta, Rakhee
Abstract:: Present day data processing technology requires very high speed signal processing and data conversion rates. One such application which requires high speed is switched capacitor circuits used in Sigma-Delta modulators. A major active component of switched capacitor circuits is the monolithic operational amplifier(opamp). Because of the relatively poor speed performance...

Millimeter-Wave Wideband Low-Noise Amplifiers in 22FFL Technology

Creator:: Gupta, Soumya
Abstract:: The deployment of advanced technology standards for 5G and beyond in cellular networks has resulted in interest in integrated circuits (ICs) operating at frequencies above 10GHz. This has sparked research on wideband circuits in commercial low-cost silicon technologies, operating at high RF and mm-wave frequencies. Given the wide range of...

Detection and diagnosis of parameters change in linear system using time-frequency transformation

Creator:: Park, Dae-hyun
Abstract:: A systematic optimization of the Cohen class time-frequency transformation for detecting the parameters change is developed. The local moments approach to change detection is proposed and a general formula for the local moments is derived. The optimal kernel functions of the time-frequency transformation are determined based on the combined criteria...

Mathematical modeling and the control of immune processes with application to cancer

Creator:: Lee, Kwon Soon
Abstract:: A foundation for the control of tumors is presented, based upon the formulation of a realistic, knowledge-based mathematical model of the interaction between tumor cells and the immune system. The parametric control variables relevant to the latest experimental data, e.g., the sigmoidal dose-response relationship and Michaelis-Menten dynamics, are also considered....

Recognizing human group activities in video through mining optimal features

Creator:: Amer, Mohamed R.
Abstract:: Given a video, we would like to recognize group activities, localize video parts where these activities occur, and detect actors involved in them. To this and, we propose a novel, mid-level feature, called control point, for representing group activities. The control points are aimed at summarizing visual cues, lifting from...

Hierarchical graphical models for activity recognition in videos

Creator:: Amer, Mohamed R.
Abstract:: This dissertation addresses the problem of recognizing human activities in videos. Our focus is on activities with stochastic structure, where the activities are characterized by variable space-time arrangements of actions, and conducted by a variable number of actors. These activities occur frequently in sports and surveillance videos. They may appear...

Modeling and testing of semi-insulating gallium arsenide interdigitated photodetectors

Creator:: Kollipara, Ravindranath Tagore
Abstract:: High speed photodetectors are a necessary element in broad band digital and analog optical communication systems. In this thesis easily integrable planar high speed photodetectors made on undoped semi-insulating (SI) GaAs substrates are modeled and tested. The fabrication process of the detectors is fully compatible with GaAs metal-semiconductor field effect...
