The work covers both theoretical and practical aspects of thermal contact conductance. The theoretical discussion focuses on heat transfer through spots, joints, and surfaces, as well as the role of interstitial materials (both planned and inadvertent). The practical discussion includes formulae and data that can be used in designing heat-transfer equipment for a variety of joints, including special geometries and configurations. All of the material has been updated to reflect the latest advances in the field.

Real-time simulations of the behaviour of a rail vehicle require realistic solutions of the wheel-rail contact problem which can work in a real-time mode. Examples of such solutions for the online mode have been well known and are implemented within standard and commercial tools for the simulation codes for rail vehicle dynamics. This book is the result of the research activities carried out by the Railway Technology Lab of the Department of Mechanical and Aerospace Engineering at Politecnico di Torino. This book presents work on the project for the development of a real-time wheel-rail contact model and provides the simulation results obtained with dSpace real-time hardware. Besides this, the implementation of the contact model for the development of a real-time model for the complex mechatronic system of a scaled test rig is presented in this book and may be useful for the further validation of the real-time contact model with experiments on a full scale test rig.

International Series in Experimental Social Psychology, Volume I: Culture in Contact: Studies in Cross-Cultural Interaction is part of a series of books that presents development in the field of social psychology; each volume contains materials such as empirical research, research procedures, theoretical formulations, and critical reviews of the relevant literature. This particular volume covers the processes and outcomes of cross cultural encounters. The book consists of eight chapters, which are organized into three parts. Part I discusses various types and purposes of cross-cultural contact and reviews the major empirical findings relating to the field. Part II deals with the processes underlying effective communication between culturally diverse persons. Part III concerns itself with practical outcomes of culture contact, such as the reactions of the persons engaged in the meeting. The text will be of great interest to researchers and professionals concerned with the nature of cross-cultural interactions, such as sociologists and social psychologists.

In thirty-three chapters, The Oxford Handbook of Language Contact examines the various forms of contact-induced linguistic change and the levels of language which have provided instances of these influences. In addition, it provides accounts of how language contact has affected some twenty languages, spoken and signed, from all parts of the world.

When happens when millions of people suddenly possess superpowers? Mathilda Brandt thought she’d protected her family and freed the world, instead she’s unleashed forces that threaten to destroy both. She rescued her Empowered mother from RAMPART, but now her mother wants Mat to choose sides-- Empowered over normal humans. Her sister Ava is missing. Governments begin rounding up the newly Empowered, while other Empowered want to end the threat from normals once and for all. With her own power suddenly erratic, and her connection to Gaia in jeopardy, how can Mat save those she loves and prevent the world from destroying itself? Empowered: Hero is the fifth and final book in Dale Ivan Smith's The Empowered series.
