Training general dynamic neural networks
(2002-08)
Measurement and analysis of natural video masked dynamic discrete cosine transform noise detectability
(2015-05)
Lossy video compression lowers fidelity and can leave visual artifacts. Current video compression algorithms are guided by quality assessment tools designed around subjective data based on aggressive video compression. ...
Front end of a 900MHz RFID for biological sensing
(2015-12)
This thesis presents the front end of a 900MHz passive RFID for biological sensing. The components blocks of the front end consist of power harvester, switch capacitor voltage regulator, phase lock loop and a modulator and ...
Studies of surface plasmons and localized surface plasmons at terahertz frequencies
(2009-12)
Scope and Method of Study: The goal of this study is to investigate the physical mechanism of field enhancement in plasmonic subwavelength structures in the terahertz regime. Such plasmonic structures were fabricated by ...
Study of photonic crystal structures by THz-TDS
(2006-12)
Scope and Method of Study: The purpose of this study was to examine the behavior of dielectric and metallic photonic crystal structures embedded in single mode metal parallel plate waveguide (PPWG). The terahertz (THz) ...
Multiobjective differential evolution based on fuzzy performance feedback: Soft constraint handling and its application in antenna designs
(2015-12)
The recently emerging Differential Evolution is considered one of the most powerful tools for solving optimization problems. It is a stochastic population-based search approach for optimization over the continuous space. ...
CMOS circuit speed and power optimization using simplified RC delay model
(2015-05)
A simplified RC delay model which is expressed explicitly in terms of transistor widths is presented to easily perform circuit analysis and quickly optimize the transistor widths for delay and power without having to do ...
Enhanced rateless coding and compressive sensing for efficient data/multimedia transmission and storage in AD-HOC and sensor networks
(2012-12)
In this dissertation, we investigate the theory and applications of the novel class of FEC codes called rateless or fountain codes in video transmission and wireless sensor networks (WSN). First, we investigate the rateless ...
