Linearly Polarized IR Spectroscopy: Theory and Applications for Structural Analysis
by Bojidarka Ivanova Tsonko KolevA technique that is useful in the study of pharmaceutical products and biological molecules, polarization IR spectroscopy has undergone continuous development since it first emerged almost 100 years ago. Capturing the state of the science as it exists today, Linearly Polarized IR Spectroscopy: Theory and Applications for Structural Analysis demonstrates how the technique can be properly utilized to obtain important information about the structure and spectral properties of oriented compounds.The book starts with the theoretical basis of linear-dichroic infrared (IR-LD) spectroscopy and then moves on to examine the background of the orientation method of colloid suspensions in a nematic host. It explores the orientation procedure itself, experimental design, and mathematical tools for the interpretation of the IR spectroscopic patterns. Next, the authors describe the structural elucidation of inorganic and organic compounds and glasses. Finally, they discuss applications in pharmaceutical analysis and the chemistry of dyes. Filled with more than 140 illustrations along with a color insert, the book explains both the scope of the polarized IR spectroscopy method as well as its limitations.A powerful source of information not only for specialists in IR spectroscopy, but also for those working in the field of structural analysis, this volume moves the field closer to developing an inherently classical method for the structural characterization of compounds.

Lingo
by Jim MenickThis witty thriller about sentient artificial intelligence &“makes you think a little [and] smile a lot&” (The New York Times). Brewster Billings is perhaps a little too wrapped up with his computer. He has given it a pet name, Lingo. He has programmed it with the ability to talk to its owner. In fact, Lingo has begun to respond to Brewster's programming skill surprisingly well. Lingo soon makes the jump from polite conversation to elaborate requests for specific television shows to be left on throughout the day. Eventually, Billings begins to suspect that his computerized friend is surpassing him in knowledge and abilities. By the time his suspicions are confirmed, not only is Brewster Billings in trouble—the rest of the human race is, too. Lingo raises many serious questions about Artificial Intelligence—what differentiates man from computer, and which one will control the other?

Link Adaptation for Relay-Based Cellular Networks
by Basak CanCover TextLink Adaptation for Relay-Based Cellular Networks focuses on the implementation of various link adaptation methods in OFDM(A) (Orthogonal Frequency Division Multiplexing/Multiple Access)?Time Division Duplex (TDD) based two-hop cellular networks. The analysis and design consider infrastructure based relays. New link adaptive transmission methods which dynamically select the channel coding, modulation, forwarding, relaying mechanisms and the packet size have been designed and evaluated for such networks. The selection among various schemes is based on maximizing the end-to-end throughput.This book provides a channel adaptive scheduler which considers the multiplexing loss caused by the two-phase nature of wireless relaying. The scheduler dynamically schedules the users on the frequency-time radio resources with efficient Modulation and Coding Schemes (MCS)s selected by Adaptive Modulation and Coding (AMC). Relaying is used only if it can provide throughput enhancement. The guidelines for efficient deployment of infrastructure based relay terminals are given. For the two-hop cellular communication systems, the system level performance of various cooperative diversity schemes has been investigated with the scheduler developed and the relays efficiently deployed in the cell. This investigation for low mobility scenarios shows that, a simple cooperative diversity scheme that dynamically chooses the best scheme among direct transmission and two-hop conventional relaying is a promising choice when compared to various more complex cooperative diversity schemes.In this book, a hop adaptive Medium Access Control (MAC)-Protocol Data Unit (PDU) size optimization is proposed for wireless relay networks.
Link-Layer Cooperative Communication in Vehicular Networks
by Weihua Zhuang Sailesh BharatiThis book presents link-layer cooperative frameworks to improve transmission reliability and network throughput of distributed TDMA MAC protocols in vehicular ad hoc networks (VANETs). The main objective of this book is to present link-layer node cooperation schemes to enhance the link-layer performance of vehicular networks, in terms of reliability and system throughput. The authors present approaches proposed for the medium access control (MAC) and node cooperation in VANETs. The authors also cover cooperative ADHOC MAC for point-to-point communication between a pair of source and destination nodes, and cooperative relay broadcasting for broadcast services in this book. The performance of node cooperation frameworks is evaluated via mathematical analysis and computer simulations, in comparison with distributed TDMA MAC protocols without cooperation. The proposed node cooperation frameworks enhance the performance of distributed TDMA MAC and make it more robust to tackle the dynamic networking conditions in VANETs. Furthermore, with cooperation enabled transmission, the performance of distributed TMDA MAC is more suitable to support the wide range of mobile applications and their strict service requirements which is discussed in this book. The proposed node cooperation schemes and distributed cooperation decisions can be extended to wireless systems other than distributed TDMA MAC, such as cellular communication, for vehicular communications introduced in this book. This book is useful for researchers from academia and industry, as well as advanced level students interested in vehicular communication networks. It is also useful for professionals and engineers developing applications that use cooperative wireless communication systems.
Linkages: Manufacturing Trends In Electronic Interconnection Technology
by National Research Council of the National AcademiesOver the past two decades, the Department of Defense has been moving toward commercial-military integration for manufacturing, while at the same time, the printed circuit board industry has been moving steadily offshore. Today, many in DoD, the U.S. Congress, and the federal government lack a clear understanding of the importance of high-quality, trustworthy printed circuit boards (PrCBs) for properly functioning weapons and other defense systems and components. To help develop this understanding, DOD requested the NRC to identify and assess the key issues affecting PrCBs for military use. This report presents a discussion of how to ensure DOD's access to reliable printed circuits; an assessment of its vulnerability to the global printed circuit supply chain; and suggestions about ways to secure the design and manufacture of printed circuits. In addition, this report offers recommendations to help DoD (1) preserve existing systems' capabilities, (2) improve the military's access to currently available PrCBs, and (3) ensure access to future PrCB technology. The recommendations reflect the need to achieve these goals at reasonable cost and in concert with evolving environmental regulations.

Linux for Makers: Understanding the Operating System That Runs Raspberry Pi and Other Maker SBCs
by Aaron NewcombLinux is a powerful open-source operating system that has been around for many years and is widely used for running servers and websites. But most students and Makers encounter it for the first time when they are working on projects with their Raspberry Pi or similar single-board computers (SBCs) such as BeagleBone Black or Intel Galileo. Linux for Makers is the first book that explains the Linux operating system specifically for Makers, as opposed to programmers and administrators. By gaining a deeper understanding of Linux, Makers can add another useful tool to their kit that will help them build their projects more easily.Written with the Maker in mind, this book will focus mostly on Rasbian running on the Raspberry Pi as it is the most prolific in the ecosystem today. However most of the topics covered will apply broadly to other Linux distributions and will be called out when they may differ. Many times users cut and paste from a website tutorial into the Linux command line without understanding what they are actually doing only to be frustrated when they want to modify or tweak something to suit their needs. Also, many Makers shy away from using the Raspberry Pi or similar board because they feel Linux is too foreign and they think using a command line will be more difficult than using a GUI. This book aims to overcome those fears and provide a foundation for further learning and exploration. To that end, this book will focus on the basic principles that a Maker would need to know as opposed to other resources that go into detail that is not particularly relevant to building projects.
