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.

2014 | ISBN: 1430265442 | English | 260 pages | PDF | 5 MB

Practical Hadoop Security
is an excellent resource for administrators planning a production Hadoop deployment who want to secure their Hadoop clusters. A detailed guide to the security options and configuration within Hadoop itself, author Bhushan Lakhe takes you through a comprehensive study of how to implement defined security within a Hadoop cluster in a hands-on way.

You will start with a detailed overview of all the security options available for Hadoop, including popular extensions like Kerberos and OpenSSH, and then delve into a hands-on implementation of user security (with illustrated code samples) with both in-the-box features and with security extensions implemented by leading vendors.

No security system is complete without a monitoring and tracing facility, so next steps you through audit logging and monitoring technologies for Hadoop, as well as ready to use implementation and configuration examples–again with illustrated code samples.

The book concludes with the most important aspect of Hadoop security – encryption. Both types of encryptions, for data in transit and data at rest, are discussed at length with leading open source projects that integrate directly with Hadoop at no licensing cost.

:

Explains importance of security, auditing and encryption within a Hadoop installation
Describes how the leading players have incorporated these features within their Hadoop distributions and provided extensions
Demonstrates how to set up and use these features to your benefit and make your Hadoop installation secure without impacting performance or ease of use

What you'll learn

Glycopolymers: Synthesis and Applications
Glycopolymers have received considerable interest in recent years due to their increasing potential applications in material science and biomedicine. With better understanding of the role of carbohydrates in biological systems and with recent advances in organic and carbohydrate chemistry, the design and synthesis of glycopolymers have become simpler where significant research efforts have been carried out towards the fabrication of advanced glyco-polymeric architectures for improved performance. This book provides an update on the recent advances on the synthesis of glycopolymers, their characterisations, their biological properties and their applications. The first objective of this book is to provide the readers a detailed overview about the synthesis of glycopolymers via several modern polymerisation techniques. The characterisation of these materials and their solution properties are also discussed. In addition to this, the conjugation of glycopolymers to different types of biomacromolecules are discussed. The second objective of this book is to provide the readers a detailed overview of the applications glycopolymers. In addition, the biological properties of the glycopolymers as a function of the types of carbohydrates attached, the polymer architectures and compositions are elaborated. This update will provide a quick reference to students and researchers working in both academia and industry.

101st Airborne: The Screaming Eagles in World War II by Mark Bando
English | Sep 15, 2007 | ISBN: 0760329842 | 256 Pages | PDF | 177,5 MB

101st Airborne: The Screaming Eagles in World War II by Mark Bando
In 1942, the 82nd Infantry Division at Camp Claiborne, Louisiana, was split in two. One of the new divisions began intense preparations and training for a surprise landing on the Nazi-occupied European continent. The location was Normandy, France; the date was June 6, 1944; and the division was the 101st Airborne: the legendary "band of brothers."

This is the story of that divisions heroic performance on D-Day, and right up to the Allied victory in Europe. Filled with historic images, many never before published, it is also a tribute to the fallen men of the 101st–the artists and athletes, scientists and mathematicians, architects and builders whose sacrifice secured the future but left the human race much diminished. Theirs is an accomplishment well-known but rarely so dramatically depicted: Here is the 101st landing on Utah Beach, coming in by parachute, or glider, or from the sea. Stirring words and pictures capture the landing, linking the Utah and Omaha beachheads; the divisions breaking of the German drive to the coast; and their brilliant stand at Bastogne; a refusal to yield so famously summed up in the commanders reply to a German call for surrender: "Nuts."

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.
