These lecture notes deal with the behavior of elastic bodies subject to small displacement gradients, namely their linearized elastic response. The framework for describing the nonlinear response of elastic bodies is first put into place and then the linearization is carried out to delineate the status of the linearized theory of elasticity. Easy reading for upper-division and first-year engineering students is provided by a balanced combination of mathematical rigor and physical understanding. This lecture note grew out of a course that the author regularly teaches to undergraduate mechanical engineering students.
Electrical Machines covers the theoretical and mathematical concepts of the most commonly used electrical machines in industry and home appliances. This book presents the practical usage and functioning of electrical machines in a way which is easily understandable by the readers. It provides a different approach from other books and presents a step by step procedure on how to start and run the machine on various load, operating, and testing conditions and connections. It also presents a complete set of readings, calculations, and graphs/plots performed on standard electrical machines with rated voltage and current. Each chapter contains answers to questions related to particular machines and testing conditions/operations, solutions to numerical problems, and some exercise problems for practice.
"A groundbreaking study in which an engaged archaeology produces nuanced understandings of the past and shapes new understandings of the present. New Philadelphia promotes a rethinking of race relations between African and European Americans."—Claire Smith, President, World Archaeological Congress "Shackel shows in explicit detail how one community archaeology project—dealing with the delicate subject of race—is being put into practice in the American Midwest. This is required reading for archaeologists and historic preservation activists who confront bondage and freedom, and who wrestle with remembrance and representation in real time."—Charles Orser, author of Race and Practice in ...
Autonomous driving is an emerging field. Vehicles are equipped with different systems such as radar, lidar, GPS etc. that enable the vehicle to make decisions and navigate without user's input, but there are still concerns regarding safety and security. This book analyses the security needs and solutions which are beneficial to autonomous driving.
The advancement of sustainable energy is becoming an important concern for many countries. The traditional electrical grid supports only one-way interaction of power being delivered to the consumers. The emergence of improved sensors, actuators, and automation technologies has consequently improved the control, monitoring and communication techniques within the energy sector, including the Smart Grid system. With the support of the aforementioned modern technologies, the information flows in two-ways between the consumer and supplier. This data communication helps the supplier in overcoming challenges like integration of renewable technologies, management of energy demand, load automation an...

Die moderne globalisierte Fertigung erfordert den Austausch eindeutiger und widerspruchsfreier Fertigungsunterlagen. Diese müssen überal gelesen und verstanden werden, um einen hohen Qualitätsanspruch gewährleisten zu können. Das ISO-Normenwerk hat hierzu das Konzept der Geometrischen Produktspezifizierung (GPS) geschaffen, welches auf CAD und die digitale Koordinatenmesstechnik ausgerichtet ist. Die GPS-Regeln geben vor, wie Bauteile in technischen Zeichnungen dimensionell, geometrisch und oberflächentechnisch zu beschreiben sind. Dafür wurden eine Vielzahl neuer Normen mit speziellen Kurzeichen, Symbolen und Regeln erlassen, die ein Konstrukteur anwenden muss, um bestimmte Produktei...
