Study and Design of Differential Microphone Arrays
Microphone arrays have attracted a lot of interest over the last few decades since they have the potential to solve many important problems such as noise reduction/speech enhancement, source separation, dereverberation, spatial sound recording, and source localization/tracking, to name a few. However, the design and implementation of microphone arrays with beamforming algorithms is not a trivial task when it comes to processing broadband signals such as speech. Indeed, in most sensor arrangements, the beamformer output tends to have a frequency-dependent response. One exception, perhaps, is the family of differential microphone arrays (DMAs) who have the promise to form frequency-independent responses. Moreover, they have the potential to attain high directional gains with small and compact apertures. As a result, this type of microphone arrays has drawn much research and development attention recently. This book is intended to provide a systematic study of DMAs from a signal processing perspective. The primary objective is to develop a rigorous but yet simple theory

for the design, implementation, and performance analysis of DMAs. The theory includes some signal processing techniques for the design of commonly used first-order, second-order, third-order, and also the general Nth-order DMAs. For each order, particular examples are given on how to form standard directional patterns such as the dipole, cardioid, supercardioid, hypercardioid, subcardioid, and quadrupole. The study demonstrates the performance of the different order DMAs in terms of beampattern, directivity factor, white noise gain, and gain for point sources. The inherent relationship between differential processing and adaptive beamforming is discussed, which provides a better understanding of DMAs and why they can achieve high directional gain. Finally, we show how to design DMAs that can be robust against white noise amplification.

Contestation and Adaptation: The Politics of National Identity in China

FREEDownload : Contestation and Adaptation: The Politics of National Identity in China

Enze Han, "Contestation and Adaptation: The Politics of National Identity in China"
2013 | ISBN-10: 0199936293 | 240 pages | PDF | 13 MB

Contestation and Adaptation: The Politics of National Identity in China
Contestation and Adaptation unravels the complexities of national-identity contestation among various ethnic minority groups in China. It focuses on the interactions between domestic and international forces that inform ethnic groups' national-identity contestation, positing a theoretical framework where international factors play a significant role in determining why and when ethnic groups will contest the national identities imposed on them by central governments as part of the nation-building process.

Simmering grievances and occasional outbursts of social unrest among ethnic minority populations in China challenge not only the ruling party's legitimacy and governance, but also contemporary Chinese national identity and the territorial integrity of the Chinese state. But, as Enze Han points out, of the fifty-five ethnic minority groups in China, only the Tibetans and Uyghurs have forcefully contested the idea of a Chinese national identity. He argues that whether ethnic groups contest those national identities depends on whether they perceive a better, achievable alternative. In particular, Han argues that ethnic groups with extensive external kinship networks are most likely to perceive a capacity to achieve better circumstances and are, therefore, more likely to politically mobilize to contest national identity. In the absence of such alternatives ethnic groups are more likely to cope with their situation through emigration, political ambivalence, or assimilation. Using this theoretical framework, the book compares the way that five major ethnic minority groups in China negotiate their national identities with the Chinese nation-state: Uyghurs, Chinese Koreans, Dai, Mongols, and Tibetans. Overall, Contestation and Adaptation sheds light on the nation-building processes in China over the past six decades and the ways that different groups have resisted or acquiesced in their dealings with the Chinese state and majority Han Chinese society.

Atomically-Precise Methods for Synthesis of Solid Catalysts by Sophie Hermans and Thierry Visart de Bocarme
English | 2014 | ISBN: 1849738297 | 316 pages | PDF | 14 MB

Atomically-Precise Methods for Synthesis of Solid Catalysts
There is much interest in preparing catalysts with specific structures for a desired catalytic activity. Although there has been a great amount of research into correlating particles sizes and microstructure to catalytic activity, knowledge about practical catalysts still remain ill-defined. The current challenge is now to understand atomic control.

provides an overview of recent developments in heterogeneous catalysts preparation which aim at controlling the microstructure of such catalysts at the atomic scale. Each chapter provides a different synthetic approach to achieve atomic-scale control along techniques to characterize the atomically-precise solids. Topics covered include bimetallic supported catalysts from single-source precursors zeolite-supported molecular metal complex catalyst, surface organometallic chemistry, atomic layer deposition and electron microscopy of catalysts.

Edited by active researchers in the area, the book aims to bridge the gap between surface science and heterogeneous catalysis. The book is suitable for graduate students as well as researchers in academia in industry from various disciplines including engineering, inorganic/organometallic chemistry, surface science and physical chemistry interested in catalyst design.

Modeling and Simulation-Based Systems Engineering Handbook

Modeling and Simulation-Based Systems Engineering Handbook (Engineering Management) by Daniele Gianni and Andrea D'Ambrogio
English | 2014 | ISBN: 1466571454 | 513 pages | PDF | 49,7 MB

Modeling and Simulation-Based Systems Engineering Handbook
The capability modeling and simulation (M&S) supplies for managing systems complexity and investigating systems behaviors has made it a central activity in the development of new and existing systems. However, a handbook that provides established M&S practices has not been available. Until now. details the M&S practices for supporting systems engineering in diverse domains. It discusses how you can identify systems engineering needs and adapt these practices to suit specific application domains, thus avoiding redefining practices from scratch.

Although M&S practices are used and embedded within individual disciplines, they are often developed in isolation. However, they address recurring problems common to all disciplines. The editors of this book tackled the challenge by recruiting key representatives from several communities, harmonizing the different perspectives derived from individual backgrounds, and lining them up with the book's vision. The result is a collection of M&S systems engineering examples that offer an initial means for cross-domain capitalization of the knowledge, methodologies, and technologies developed in several communities. These examples provide the pros and cons of the methods and techniques available, lessons learned, and pitfalls to avoid.

As our society moves further in the information era, knowledge and M&S capabilities become key enablers for the engineering of complex systems and systems of systems. Therefore, knowledge and M&S methodologies and technologies become valuable output in an engineering activity, and their cross-domain capitalization is key to further advance the future practices in systems engineering. This book collates information across disciplines to provide you with the tools to more efficiently design and manage complex systems that achieve their goals.

Thomas C. Henderson, "Computational Sensor Networks"
2009 | pages: 228 | ISBN: 0387096426 | PDF | 8,5 mb

Computational Sensor Networks
A model-based approach to the design and implementation of (CSNs) is proposed. This high-level paradigm for the development and application of sensor device networks provides a strong scientific computing foundation, as well as the basis for robust software engineering practice. The three major components of this approach include (1) models of phenomena to be monitored, (2) models of sensors and actuators, and (3) models of the sensor network computation. We propose guiding principles to identify the state or structure of the phenomenon being sensed, or of the sensor network itself. This is called computational modeling. These methods are then incorporated into the operational system of the sensor network and adapted to system performance requirements to produce a mapping of the computation onto the system architecture. This is called real-time computational mapping and allows modification of system parameters according to real-time performance measures. This book deals with the development of a mathematical and modular software development framework to achieve computational sensor networks.
