Principles and Applications of Powder Diffraction

FREEDownload : Principles and Applications of Powder Diffraction

Principles and Applications of Powder Diffraction
English | Physics | 5. September 2008 | ISBN-10: 1405162228 | 400 pages | pdf | 10 mb
Powder diffraction is one of the primary techniques used to characterize materials, providing structural information even when the crystallite size is too small for single crystal x-ray diffraction methods.

Principles and Applications of Powder Diffraction
There has been a significant increase in the application of powder diffraction in recent years, both in research and manufacturing, fuelled by improved instrumentation, data processing and awareness of the information that can be obtained. Powder diffraction allows for rapid, non-destructive analysis of multi-component mixtures without the need for extensive sample preparation. This gives laboratories the ability to quickly analyse unknown materials and perform materials characterization in such fields as chemistry, materials science, geology, mineralogy, forensics, archaeology, and the biological and pharmaceutical sciences.

This book provides a concise introduction to modern powder diffraction methods with particular emphasis on practical aspects. It covers the background theory of diffraction in a form approachable by those with an undergraduate degree. Whilst individual chapters are written as stand alone sections, the text is sufficiently focused so that it can be read in its entirety by the non-specialist who wants to gain a rapid overview of what they can do with modern powder diffraction methods.

Bioarchaeology and Behavior: The People of the Ancient Near East by Megan A. Perry
English | 2012 | ISBN: 0813042291 | 212 pages | PDF | 4 MB

Bioarchaeology and Behavior: The People of the Ancient Near East
While mortuary ruins have long fascinated archaeologists and art historians interested in the cultures of the Near East and eastern Mediterranean, the human skeletal remains contained in the tombs of this region have garnered less attention. In Bioarchaeology and Behavior, Megan Perry presents a collection of essays that aim a spotlight on the investigation of the ancient inhabitants of the circum-Mediterranean area.

Composed of eight diverse papers, this volume synthesizes recent research on human skeletal remains and their archaeological and historical contexts in this region. Utilizing an environmental, social, and political framework, the contributors present scholarly case studies on such topics as the region's mortuary archaeology, genetic investigations of migration patterns, and the ancient populations' health, disease, and diet. Other key anthropological issues addressed in this volume include the effects of the domestication of plants and animals, the rise of state-level formations, and the role of religion in society. Ultimately, this collection will provide anthropologists, archaeologists, and bioarchaeologists with an important foundation for future research in the Near East and eastern Mediterranean.

Study and Design of Differential Microphone Arrays

FREEDownload : Study and Design of Differential Microphone Arrays

Jacob Benesty, Jingdong Chen, "Study and Design of Differential Microphone Arrays"
English | 2013 | ISBN-10: 364233752X, 3642427561 | 180 pages | PDF | 6 MB

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.

The Uncanny Valley in Games and Animation

The Uncanny Valley in Games and Animation by Angela Tinwell
2014 | ISBN: 146658694X | English | 236 pages | PDF | 11 MB

The Uncanny Valley in Games and Animation
Advances in technology have enabled animators and video game designers to design increasingly realistic, human-like characters in animation and games. Although it was intended that this increased realism would allow viewers to appreciate the emotional state of characters, research has shown that audiences often have a negative reaction as the human likeness of a character increases. This phenomenon, known as the Uncanny Valley, has become a benchmark for measuring if a character is believably realistic and authentically human like. This book is an essential guide on how to overcome the Uncanny Valley phenomenon when designing human-like characters in digital applications.

In this book, the author provides a synopsis of literature about the Uncanny Valley phenomenon and explains how it was introduced into contemporary thought. She then presents her theories on its possible psychological causes based on a series of empirical studies. The book focuses on how aspects of facial expression and speech can be manipulated to overcome the Uncanny Valley in character design.

presents a novel theory that goes beyond previous research in that the cause of the Uncanny Valley is based on a perceived lack of empathy in a character. This book makes an original, scholarly contribution to our current understanding of the Uncanny Valley phenomenon and fills a gap in the literature by assessing the biological and social roots of the Uncanny Valley and its implications for computer-graphics animation.
