Designed to develop greater understanding of the principles of signals and systems, these computer exercises make direct connections between theory and application. Using. 670 pages. This book is a self-contained introduction to the theory of signals and systems, which lies at the basis of many areas of electrical and computer engineering. In the(More)
omplex dynamic systems such as aircraft, power systems, and telecommunication networks present major challenges to control systems designers. Both the military and civilian sectors of our economy are demanding new and highly sophisticated capabilities from these systems that traditional controls technology is not offering. Among these capabilities are the(More)
Complex control systems often contain numerous controllers (or control laws) for a given plant, where the controller having authority at any given time depends on the current operating condition of the plant. For example, a plant operating in the nominal condition generally uses one controller, while a plant with a fault uses a different controller. Even in(More)
Recent advances in software technology have the potential to revolutionize control system design. This paper describes a new software infrastructure for complex control systems, which exploits new and emerging software technologies. It presents an open control platform (OCP) for complex systems, including those that must be reconfigured or customized in(More)
A sensor network consists of a set of battery-powered nodes, which collaborate to perform sensing tasks in a given environment. It may contain one or more base stations to collect sensed data and possibly relay it to a central processing and storage system. These networks are characterized by scarcity of resources, in particular the available energy. We(More)

My deepest thanks are for Professor George J. Vachtsevanos, who advised me through the completion of this work. His(More)
The plasma membranes of the glycogen-free and the glycogen-containing subline of Ehrlich-Lettrè ascites cells were purified and compared with respect to their enzyme activity, chemical, lipid and protein composition, and membrane fluidity. Both membrane fractions differed in a number of parameters which are discussed as differences in the expression of(More)

— Distributed event detection using wireless sensor networks has received growing interest in recent years. In such applications, a large number of inexpensive and unreliable sensor nodes are distributed in a geographical region to make firm and accurate local decisions about the presence or absence of specific events based on their sensor readings.(More)
ACKNOWLEDGEMENTS I am very grateful to my research advisor, Dr. David Taylor, my parents, and my friends who had given me encouragement and support throughout my graduate studies. Dr. Taylor had given me countless advise. When I almost gave up, he was there to encourage me to keep working. My parents, who I have not seen for several years, always called and(More)
