Acting Principles of Nano-Scaled Matrix Additives for Composite Structures (Research Topics in Aerospace)
by Michael Sinapius Gerhard ZiegmannThe book explores the effect of nanoscale matrix additives along the four levels of material formation, particle-resin interaction, the influence of nanoparticles on the processability of the polymer, the influence of nanoparticles on polymer curing and the influence of nanoparticles on the fiber plastic composite. Fiber-reinforced plastics have a significantly higher lightweight construction potential in components with a primary single- or biaxial stress state compared to isotropic metals. At the same time, their insensitivity to corrosion and their advantageous fatigue properties can help to reduce maintenance costs. Due to their outstanding specific mechanical properties, they are among today's high-performance lightweight construction materials. These properties make them particularly attractive in the field of mobility. However, as soon as the matrix properties dominate the mechanical properties, e.g. in the case of fibre-parallel compressive strength, significant weaknesses become apparent in the mechanical properties. Here, one approach is to significantly increase the matrix properties through nanoscale ceramic additives and at the same time to guarantee the processability of the resin.

ACS Without an Attitude (NASA Monographs in Systems and Software Engineering)
by Christopher Rouff Harold L. Hallock Gary Welter David G. SimpsonThis book de-emphasizes the formal mathematical description of spacecraft on-board attitude and orbit applications in favor of a more qualitative, concept-oriented presentation of these topics. The information presented in this book was originally given as a set of lectures in 1999 and 2000 instigated by a NASA Flight Software Branch Chief at Goddard Space Flight Center. The Branch Chief later suggested this book. It provides an approachable insight into the area and is not intended as an essential reference work. ACS Without an Attitude is intended for programmers and testers new to the field who are seeking a commonsense understanding of the subject matter they are coding and testing in the hope that they will reduce their risk of introducing or missing the key software bug that causes an abrupt termination in their spacecraft's mission. In addition, the book will provide managers and others working with spacecraft with a basic understanding of this subject.

Acquired Tastes: Stories about the Origins of Modern Food (Food, Health, and the Environment)
by Benjamin R. Cohen, Michael S. Kideckel, and Anna ZeideHow modern food helped make modern society between 1870 and 1930: stories of power and food, from bananas and beer to bread and fake meat.The modern way of eating—our taste for food that is processed, packaged, and advertised—has its roots as far back as the 1870s. Many food writers trace our eating habits to World War II, but this book shows that our current food system began to coalesce much earlier. Modern food came from and helped to create a society based on racial hierarchies, colonization, and global integration. Acquired Tastes explores these themes through a series of moments in food history—stories of bread, beer, sugar, canned food, cereal, bananas, and more—that shaped how we think about food today. Contributors consider the displacement of native peoples for agricultural development; the invention of Pilsner, the first international beer style; the &“long con&” of gilded sugar and corn syrup; Josephine Baker&’s banana skirt and the rise of celebrity tastemakers; and faith in institutions and experts who produced, among other things, food rankings and fake meat.

Acoustics of Bangla Speech Sounds (Signals and Communication Technology)
by Asoke Kumar DattaThis book presents the consolidated acoustic data for all phones in Standard Colloquial Bengali (SCB), commonly known as Bangla, a Bengali language used by 350 million people in India, Bangladesh, and the Bengali diaspora. The book analyzes the real speech of selected native speakers of the Bangla dialect to ensure that a proper acoustical database is available for the development of speech technologies. The acoustic data presented consists of averages and their normal spread, represented by the standard deviations of necessary acoustic parameters including e. g. formant information for multiple native speakers of both sexes. The study employs two important speech technologies:(1) text to speech synthesis (TTS) and (2) automatic speech recognition (ASR). The procedures, particularly those related to the use of technologies, are described in sufficient detail to enable researchers to use them to create technical acoustic databases for any other Indian dialect. The book offers a unique resource for scientists and industrial practitioners who are interested in the acoustic analysis and processing of Indian dialects to develop similar dialect databases of their own.
