Dedication To My Parents For their love, sacrifice, encouragement, and patience and Ajji Whose memories shall always be with me iv Acknowledgments My advisor, Prof. Tom Little, has constantly inspired me to set high goals for myself and helped me attain them. Ever since I became a member of the Multimedia Communications Laboratory, Tom has enthusiastically guided my research and was patient as ...

In this chapter, we present a demodulation structure suitable for a reader baseband receiver in a passive Radio Frequency IDentification (RFID) environment. RFID refers to a technology which uses radio communications to contactlessly identify a tagged physical object [1-2]. An RFID system may include a plurality of electronic tags on objects, animals, and other things having unique identificati...

The Electronic Braille Document Reader project was to evaluate the feasibility of a device which could read Latin text and convert it to Braille pattern which could be read through a single Braille cell. A device which mimics the advantages of an e-book reader but suited to the needs of the blind.

The coordination of multifunction phased array radars across networked platforms can enable superior functionality and battle space awareness. This thesis formulates and solves a number of optimization models and heuristic algorithms to analyze and prescribe radarto-target assignments and schedules. One optimization model uses full target information to provide a “best case” assessment of the a...

Speeder Reader is an interactive reading station built around two primary ideas: dynamic text (especially RSVP, that is, rapid serial visual presentation), and the interface metaphor of driving. As words flash one at a time on a screen in front of the reader, he or she controls the rate of speed of the words with a gas pedal (up to 1850 words per minute in the current instance). Text stream sel...

In this paper, tagging techniques are employed to identify monitored inhabitants in smart environments. The aim of the work is to recognize the presence of the tagged inhabitants in different areas of the environment. RSSI based localizing agents are used in separate areas to measure the distance of the tagged persons from the reader agents. Then a clustering method is applied to the readings f...

One of the biggest challenges in RFID (radio frequency identification) large scale deployment, such as in warehouse RFID deployment, is the positioning of RFID reader antennas to efficiently locate all the tagged objects distributed at RFID reader environment. This paper has investigated a novel location sensing system based on geometric grid covering algorithm that can use any passive or activ...
