When choosing the technology options to develop a wireless sensor network (WSN), it is vital that their performance levels can be assessed for the type of application intended. This book describes the different technology options - MAC protocols, routing protocols, localisation and data fusion techniques - and provides the means to numerically measure their performance, whether by simulation, mathematical models or experimental test beds. Case studies, based on the authors' direct experience of implementing wireless sensor networks, describe the design methodology and the type of measurements used, together with samples of the performance measurements attained.
The book will enable you to answer vital questions such as:
* How long will my network remain alive given the amount of sensing required of it?
* For how long should I set the sleeping state of my motes?
* How many sensors should I distribute to meet the expected requirements of the application?
* What type of throughput should I expect as a function of the number of nodes deployed and the radio interface chosen (whether it be Bluetooth or Zigbee)?
* How is the Packet Error Rate of my Zigbee motes affected by the selection of adjacent frequency sub bands in the ISM 2.4GHz band?
* How is the localisation precision dependant on the number of nodes deployed in a corridor?
Communications and signal processing engineers, researchers and graduate students working in wireless sensor networks will find this book an invaluable practical guide to this important technology.

Risk model validation is an emerging and important area of research, and has arisen because of Basel I and II. These regulatory initiatives require trading institutions and lending institutions to compute their reserve capital in a highly analytic way, based on the use of internal risk models. It is part of the regulatory structure that these risk models be validated both internally and externally, and there is a great shortage of information as to best practise. Editors Christodoulakis and Satchell collect papers that are beginning to appear by regulators, consultants, and academics, to provide the first collection that focuses on the quantitative side of model validation. The book covers the three main areas of risk: Credit Risk and Market and Operational Risk.
*Risk model validation is a requirement of Basel I and II
*The first collection of papers in this new and developing area of research
*International authors cover model validation in credit, market, and operational risk

Gambling, prostitution and bootlegging have been going on in Steubenville for well over one hundred years. Its Water Street red-light district drew men from hundreds of miles away, as well as underage runaways. The white slave trade was rampant, and along with all the vice crimes, murders became a weekly occurrence. Law enforcement seemed to turn a blind eye, and cries of political corruption were heard in the state capital. This scenario replayed itself over and over again during the past century as mobsters and madams ruled and murders plagued the city and county at an alarming rate. Newspapers nationwide would come to nickname this mecca of murder "Little Chicago."

In late July 1910, a shocking number of African Americans in Texas were slaughtered by white mobs in the Slocum area of Anderson County and the Percilla-Augusta region of neighboring Houston County. The number of dead surpassed the casualties of the Rosewood Massacre in Florida and rivaled those of the Tulsa Riots in Oklahoma, but the incident--one of the largest mass murders of blacks in American history--is now largely forgotten. Investigate the facts behind this harrowing act of genocide in E.R. Bills's compelling inquiry into the Slocum Massacre.

From the US Capitol to the Lincoln Memorial and the 9/11 Memorial Museum, classical forms and ideas have been central to an American nationalist aesthetic. Beginning with an understanding of this centrality of the classical tradition to the construction of American national identity and the projection of American power, Empire of Ruin describes a mode of black classicism that has been integral to the larger critique of American politics, aesthetics, and historiography that African American cultural production has more generally advanced. While the classical tradition has provided a repository of ideas and images that have allowed white American elites to conceive of the nation as an ideal Republic and the vanguard of the idea of civilization, African American writers, artists, and activists have characterized this dominant mode of classical appropriation as emblematic of a national commitment to an economy of enslavement and a geopolitical project of empire. If the dominant forms of American classicism and monumental culture have asserted the ascendancy of what Thomas Jefferson called an "empire for liberty," for African American writers and artists it has suggested that the nation is nothing exceptional, but rather another iteration of what the radical abolitionist Henry Highland Garnet identified as an "empire of slavery," inexorably devolving into an "empire of ruin."

The racial injustice that continues to plague the United States couldn't be a clearer challenge to the country's idea of itself as a liberal and democratic society, where all citizens have a chance at a decent life. Moreover, it raises deep questions about the adequacy of our political ideas, particularly liberal political theory, to guide us out of the quagmire of inequality. So what does justice demand in response? What must a liberal society do to address the legacies of its past, and how should we aim to reconceive liberalism in order to do so? In this book, Andrew Valls considers two solutions, one posed from the political right and one from the left. From the right is the idea that norms of equal treatment require that race be treated as irrelevant-in other words, that public policy and political institutions be race-blind. From the left is the idea that race-conscious policies are temporary, and are justifiable insofar as they promote diversity. This book takes issue with both of these sets of views, and therefore with the constricted ways in which racial justice is debated in the United States today. Valls argues that liberal theory permits, and in some cases requires, race-conscious policies and institutional arrangements in the pursuit of racial equality. In doing so, he aims to do two things: first, to reorient the terms of racial justice and, secondly, to make liberal theory confront its tendency to ignore race in favor of an underspecified commitment to multiculturalism. He argues that the insistence that race-conscious policies be temporary is harmful to the cause of racial justice, defends black-dominated institutions and communities as a viable alternative to integration, and argues against the tendency to subsume claims for racial justice, particularly as they regard African Americans, under more general arguments for diversity.

Since its recent introduction, the ZigBee protocol has created an enormous amount of buzz in venues from magazine covers to trade show floors to water coolers. Its promise of providing a simpler, cheaper, more power-efficient WPAN (Wireless Personal Area Network) alternative to WiFi and Bluetooth has opened up new data collection possibilities in application areas from industrial controls to medical devices to intruder alarms. Yet, despite this widespread interest, there is still little information available that goes beyond detailing the spec itself. Missing from the current ZigBee lexicon is practical, application-oriented guidance from an expert, specifically geared to aid engineers in implementing this new technology. Enter respected designer and popular columnist Fred Eady! With his new book, he provides the only comprehensive how-to ZigBee guide available.
-The ONLY one-stop Zigbee resource available- from basics to sniffers to specs
-7 easy-to-assemble ZigBee projects allow the reader to follow along...hands-on!

A large amount of natural or artificially produced physical phenomena are exploited for practical applications, even though several of them give rise to unpleasant consequences. These ultimately manifest themselves under form of malfunction or definitive failure of components and systems, or environmental hazard. So far, manifold categories of inadvertent or deliberate sources have been discovered to simultaneously produce useful effects in some ways but adverse ones in others. In particular, responsible for the growing interest in the last decades for Electromagnetic Compatibility (EMC) has been the progressive miniaturisation and sensitivity of electronic components and circuits, often operating in close proximity to relatively powerful sources of electromagnetic interference. Potential authors of books on the subject-matter are fully aware of the fact that planning production of manageable handbooks capable to treat all the EMC case studies of practical and long-lasting interest could result in a questionable and difficult undertaking. Therefore, in addition to textbooks providing a thorough background on basic aspects, thus being well-tailored for students and those which want to get in contact with this discipline, the most can be made to jointly sustain a helpful and practicable publishing activity is to supply specialised monographs or miscellanies of selected topics. Such resources are preferentially addressed to post-graduate students, researchers and designers, often employed in the forefront of research or engaged for remodelling design paradigms. Hence, the prerequisite for such a class of publications should consist in arousing critical sense and promoting new ideas. This is the object of the present book which tries to rather discuss special subjects, or throw out suggestions for reformulating conventional approaches, than to appear as a reference text. A common motivation encouraged the contributors to bringing together a number of accounts of the research that they have undertaken over the late years: willing to fill the important need of covering EMC topics rather proper to transmission and distribution of electric power than, more usually, to Electronics and Telecommunication Systems.
- EMC topics for Power Systems, at last
- Investigating EMC features of distributed and/or complex systems.
- A broad body of knowledge for specific applications.
- A stimulating support for those which are engaged in the forefront of research and design.
- An example of how breaking ideas should be encouraged and proudly applied.
- A fruitful critique to overcomplicated and unpractical models.
- A comprehensive resource to estimate the important role of EMC at lower frequencies.

Universities are unlikely venues for grading, branding, and marketing beauty, bodies, poise, and style. Nonetheless, thousands of college women have sought not only college diplomas but campus beauty titles and tiaras throughout the twentieth century. The cultural power of beauty pageants continues today as campus beauty pageants, especially racial and ethnic pageants and pageants for men, have soared in popularity. In Queens of Academe, Karen W. Tice asks how, and why, does higher education remain in the beauty and body business and with what effects on student bodies and identities. She explores why students compete in and attend pageants such as "Miss Pride" and "Best Bodies on Campus" as well as why websites such as "Campus Chic" and campus-based etiquette and charm schools are flourishing. Based on archival research and interviews with contemporary campus queens and university sponsors as well as hundreds of hours observing college pageants on predominantly black and white campuses, Tice examines how campus pageant contestants express personal ambitions, desires, and, sometimes, racial and political agendas to resolve the incongruities of performing in evening gowns and bathing suits on stage while seeking their degrees. Tice argues the pageants help to illuminate the shifting terrain of class, race, religion, sexuality, and gender braided in campus rituals and student life. Moving beyond a binary of objectification versus empowerment, Tice offers a nuanced analysis of the contradictory politics of education, feminism, empowerment, consumerism, race and ethnicity, class, and popular culture have on students, idealized masculinities and femininities, and the stylization of higher education itself.

This volume offers a representative selection of Sally McConnell-Ginet's publications on language, gender and sexuality, which circle around the following themes: language users are actively engaged in making meanings, both as speakers and listeners; languages and socio-political institutions constrain, but do not determine, communicative possibilities; attention to language deepens understanding of gender and sexuality, including connections to ethnicity, class, race, and other dimensions of social identity and inequality.

What do people do all day? What did women and men do to make a living in early modern Europe, and what did their work mean? As this book shows, the meanings depended both on the worker and on the context. With an innovative analytic method that is yoked to a specially-built database of source materials, this book revises many received opinions about the history of gender and work in Europe. The applied verb-oriented method finds the 'work verbs' that appear incidentally in a wide variety of early modern sources and then analyzes the context in which they appear. By tying information technologies and computer-assisted analysis to the analytic powers - both quantitative and qualitative - of professional historians, the method gets much closer to a participatory observation of the micro-patterns of early modern life than was once believed possible. It directly addresses a number of broad problems often debated by historians of gender and early modern Europe. First, it discusses the problem of assessing more accurately the incidence, character and division of work. Second, it analyzes the configurations of work and human difference. Third, it deals with the extent to which work practices created notions of difference - gender difference but also other forms of difference - and, conversely, to what extent work practices contributed to notions of sameness and gender convergence. Finally, it studies the impact of processes of change. Drawing on sources from Sweden, the authors show the importance of multiple employment, the openness of early modern households, the significance of marriage and marital status, the gendered nature of specific tasks, and the ways in which state formation and commercialization were entangled in people's everyday lives.

For a long time, conventional reliability analyses have been oriented towards selecting the more reliable system and preoccupied with maximising the reliability of engineering systems. On the basis of counterexamples however, we demonstrate that selecting the more reliable system does not necessarily mean selecting the system with the smaller losses from failures! As a result, reliability analyses should necessarily be risk-based, linked with the losses from failures.
Accordingly, a theoretical framework and models are presented which form the foundations of the reliability analysis and reliability allocation linked with the losses from failures.
An underlying theme in the book is the basic principle for a risk-based design: the larger the cost of failure associated with a component, the larger its minimum necessary reliability level. Even identical components should be designed to different reliability levels if their failures are associated with different losses.
According to a classical definition, the risk of failure is a product of the probability of failure and the cost given failure. This risk measure however cannot describe the risk of losses exceeding a maximum acceptable limit. Traditionally the losses from failures have been 'accounted for' by the average production availability (the ratio of the actual production capacity and the maximum production capacity). As demonstrated in the book by using a simple counterexample, two systems with the same production availability can be characterised by very different losses from failures.
As an alternative, a new aggregated risk measure based on the cumulative distribution of the potential losses has been introducedand the theoretical framework for risk analysis based on the concept potential losses has also been developed. This new risk measure incorporates the uncertainty associated with the exposure to losses and the uncertainty in the consequences given the exposure. For repairable systems with complex topology, the distribution of the potential losses can be revealed by simulating the behaviour of systems during their life-cycle. For this purpose, fast discrete event-driven simulators are presented capable of tracking the potential losses for systems with complex topology, composed of a large number of components. The simulators are based on new, very efficient algorithms for system reliability analysis of systems comprising thousands of components.
An important theme in the book are the generic principles and techniques for reducing technical risk. These have been classified into three major categories: preventive (reducing the likelihood of failure), protective (reducing the consequences from failure) and dual (reducing both, the likelihood and the consequences from failure). Many of these principles (for example: avoiding clustering of events, deliberately introducing weak links, reducing sensitivity, introducing changes with opposite sign, etc.) are discussed in the reliability literature for the first time.
Significant space has been allocated to component reliability. In the last chapter of the book, several applications are discussed of a powerful equation which constitutes the core of a new theory of locally initiated component failure by flaws whose number is a random variable.
This book has been written with the intention to fill two big gaps in the reliability and riskliterature: the risk-based reliability analysis as a powerful alternative to the traditional reliability analysis and the generic principles for reducing technical risk. I hope that the principles, models and algorithms presented in the book will help to fill these gaps and make the book useful to reliability and risk-analysts, researchers, consultants, students and practising engineers.
