Energy Scavenging for Wireless Sensor Networks: With Special Focus on Vibrations
The vast reduction in size and power consumption of CMOScircuitry has led to a large research effort based around the visionof ubiquitous networks of wireless communication nodes. The wirelessdevices are usually designed to run on batteries. However, as thenetworks increase in number and the devices decrease in size, thereplacement of depleted batteries is not practical. Furthermore, abattery that is large enough to last the lifetime of the device woulddominate the overall system size, and thus is not very attractive.There is clearly a need to explore alternative methods of poweringthese small communication nodes. This book, therefore, focuses onpotential "ambient" sources of power that can be scavenged orharvested and subsequently used to run low power electronics andwireless transceivers.A wide range of potential power sources are briefly explored. Based ona comparison of these many potential sources, commonly occurringvibrations was chosen as an attractive, and little explored, powersource. Models for different types of power converters using bothelectrostatic and piezoelectric conversion mechanisms have beendeveloped. The models have been validated by testing prototypes drivenat vibrations similar to those found in many industrial and commercialbuilding environments. Finally, integration of a piezoelectricgenerator, power circuit, and custom design radio transceiver isdemonstrated.Power sources are becoming a bottleneck to the widespread deploymentof wireless sensor networks. This work reviews many potentialalternative sources of ambient power that can be scavenged. Vibrationto electricity converters are explored in great detail, and based onstudies and experiments, are shown to bean attractive power source inmany applications."Energy Scavenging for Wireless Sensor Networks with Special Focuson" "Vibrations" will be of interest to researchers andprofessionals in the areas of wireless electronics, smart structuresand MEMS as well as power electronics.

Focus Groups as Qualitative Research / David L. Morgan by David L. Morgan, ISBN 0761903429
The extensively revised edition of the best-selling Focus Groups as Qualitative Research continues to provide an excellent guide for researchers across the disciplines.
Reflecting the many changes that have occurred in the study of focus groups in recent years, the book begins with an updated introduction offering a discussion of current social science approaches to focus groups. Expanded coverage on the comparison of focus groups to individual interviews follows, and there is more material on the strengths and weaknesses of focus groups. The section on self-contained focus groups has also been expanded. Subsequent chapters have been revised to include examples from social scientists who have established their own practices and methodological research on focus groups. In conclusion, the author offers future directions and references that take into account the explosive growth of focus groups as a research tool for all social scientists.

Birmingham's Theater and Retail District
From the 1890s to the 1970s, the thriving area of Birmingham between Eighteenth and Twenty-first Streets along First, Second, and Third Avenues was the bustling heart of this quickly growing city. Before the age of the shopping mall, the downtown was the center of retail and entertainment in Birmingham. Along these streets, entrepreneurial immigrants built department stores--including Pizitz and Loveman, Joseph, and Loeb--while the marquees of the Alabama, Ritz, and Lyric theaters, among others, shined over the busy downtown sidewalks.

Digital Electronics Demystified
The field of teaching digital electronics has not changed significantly in the past 20 years. Many of the same books that first became available in the late 1970s and early 1980s are still being used as basic texts. In the 20+ years since these were written, the basic rules have not changed, but they do not provide strong links to modern electronics including CMOS logic, Programmable Logic Devices and microprocessor/microcontroller interfacing. Courses teaching introductory digital electronics...
