Book Description
This historical exploration of the Green Book offers “a fascinating [and] sweeping story of black travel within Jim Crow America across four decades” (The New York Times Book Review). Published from 1936 to 1966, the Green Book was hailed as the “black travel guide to America.” At that time, it was very dangerous and difficult for African-Americans to travel because they couldn’t eat, sleep, or buy gas at most white-owned businesses. The Green Book listed hotels, restaurants, gas stations, and other businesses that were safe for black travelers. It was a resourceful and innovative solution to a horrific problem. It took courage to be listed in the Green Book, and Overground Railroad celebrates the stories of those who put their names in the book and stood up against segregation. Author Candacy A. Taylor shows the history of the Green Book, how we arrived at our present historical moment, and how far we still have to go when it comes to race relations in America. A New York Times Notable Book of 2020

Book Description
This book constitutes the thoroughly refereed post-proceedings of three workshops and an industrial track held in conjunction with the 11th Pacific-Asia Conference on Knowledge Discovery and Data Mining, PAKDD 2007, held in Nanjing, China in May 2007. The 62 revised full papers presented together with an overview article to each workshop were carefully reviewed and selected from 355 submissions.

Book Description
This book presents a survey of past and recent developments on human walking in virtual environments with an emphasis on human self-motion perception, the multisensory nature of experiences of walking, conceptual design approaches, current technologies, and applications. The use of Virtual Reality and movement simulation systems is becoming increasingly popular and more accessible to a wide variety of research fields and applications. While, in the past, simulation technologies have focused on developing realistic, interactive visual environments, it is becoming increasingly obvious that our everyday interactions are highly multisensory. Therefore, investigators are beginning to understand the critical importance of developing and validating locomotor interfaces that can allow for realistic, natural behaviours. The book aims to present an overview of what is currently understood about human perception and performance when moving in virtual environments and to situate it relative to the broader scientific and engineering literature on human locomotion and locomotion interfaces. The contents include scientific background and recent empirical findings related to biomechanics, self-motion perception, and physical interactions. The book also discusses conceptual approaches to multimodal sensing, display systems, and interaction for walking in real and virtual environments. Finally, it will present current and emerging applications in areas such as gait and posture rehabilitation, gaming, sports, and architectural design.

Book Description
The purpose of the package is to answer the question 'What is the radio field strength at a certain point?' when power is radiated from a transmit ting source. Because of the complexity of the question in general, it can only be answered at present in certain idealized situations. Nevertheless it is valuable to have quantitative data available for these situations. The package is divided into two parts. In the first of these, propagation in free space and over a flat earth are dealt with. In the second, propagation over a spherical earth is considered. In the free-space situation the power density of the signal in a given direction will fall as the inverse square of the distance from the source. For propagation from a transmitting source at an arbitrary height above a perfecdy conducting flat earth, the field strength at large distances can be 3 dB higher than in free space. With a finite conduc tivity earth, the field strength will be lower than this because of the power dissipation in the earth.

Book Description
This volume investigates the English spatial preposition over and prepositions in general, frequently regarded as function words with little semantic content, and shows that they encode rich and diverse information, both grammatical and semantic. An important research endeavor which the present study undertakes is an examination of whether the meaning of the preposition over is in fact complex enough for the preposition to be treated as a lexical unit rather than merely a functional one. In order to achieve that goal, the gathered linguistic material is analyzed first and foremost in terms of its semantic content; that is, the geometric relations between the trajector and landmark, and the functional consequences of such relations. The research into the morphology of prepositions reveals a considerable area of overlap between prepositions and adverbs, adverbial particles, and prefixes, as well as nouns, verbs and adjectives. The discussion of the syntax of prepositions is illustrated with labeled tree diagrams of selected sentences to show how the preposition over and the prepositional phrases it heads are embedded in larger structures of the English sentence. An important finding of the present study is the confirmation that the spatial preposition over encodes a broad range of geometrical and functional relations, as well as rich grammatical information. This book will be of interest to students and researchers interested in semantic and conceptual aspects of prepositions, meaning construction, human cognition, and management of space.
