Design and Simulation of Rail Vehicles
Keep Up with Advancements in the Field of Rail Vehicle DesignA thorough understanding of the issues that affect dynamic performance, as well as more inventive methods for controlling rail vehicle dynamics, is needed to meet the demands for safer rail vehicles with higher speed and loads. Design and Simulation of Rail Vehicles examines the field of
Rail Vehicle Mechatronics
This unique and up-to-date work surveys the use of mechatronics in rail vehicles, notably traction, braking, communications, data sharing, and control. The results include improved safety, comfort, and fuel efficiency. Mechatronic systems are a key element in modern rail vehicle design and operation. Starting with an overview of mechatronic theory, the book covers such topics as modeling of mechanical and electrical systems for rail vehicles, open and closed loop control systems, sensors, actuators, and microprocessors. Modern simulation techniques and examples are included throughout the book. Numerical experiments and developed models for railway application are presented and explained. Ca...
COVID-19 and Education in Africa
With comprehensive examples from researchers across East Africa, West Africa, and Southern Africa, the book examines how primary, secondary, and tertiary education was affected by the pandemic and how its effects are shaping the future of education in Africa. This book addresses diverse issues relating to COVID-19 and education, including the gendered-, classed-, and disability-related effects of the pandemic; African educators’ and students’ experiences with different remote learning technologies; and the outcomes of government interventions in education, such as prolonged school closures. The chapters and case studies highlighted in the volume represent the voices of African educators, students, and parents as they share their experiences of the pandemic and their perspectives on how learning should be optimised to better manage future disruptions to education. This book is the first of its kind to comprehensively examine the effects of COVID-19 on education in Africa and will be essential reading for researchers, academics, and scholars of African education, international and comparative education, and education policy.
The Moving Appeal
Ellis relates the story of the Memphis Daily Appeal , the mobile newspaper that rallied Southern civilians and soldiers during the Civil War, and eluded capture by Yankee generals who chased the Appeal's portable printing operation across four states. The study also serves as a biography of the news
Design and Simulation of Heavy Haul Locomotives and Trains
With the increasing demands for safer freight trains operating with higher speed and higher loads, it is necessary to implement methods for controlling longer, heavier trains. This requires a full understanding of the factors that affect their dynamic performance. Simulation techniques allow proposed innovations to be optimised before introducing them into the operational railway environment. Coverage is given to the various types of locomotives used with heavy haul freight trains, along with the various possible configurations of those trains. This book serves as an introductory text for college students, and as a reference for engineers practicing in heavy haul rail network design,
Automotive Accident Reconstruction
This fully updated edition presents practices and principles applicable for the reconstruction of automobile and commercial truck crashes. Like the First Edition, it starts at the very beginning with fundamental principles, information sources, and data gathering and inspection techniques for accident scenes and vehicles. It goes on to show how to analyze photographs and crash test data. The book presents tire fundamentals and shows how to use them in spreadsheet-based reverse trajectory analysis. Such methods are also applied to reconstructing rollover crashes. Impacts with narrow fixed objects are discussed. Impact mechanics, structural dynamics, and conservation-based reconstruction methods are presented. The book contains a comprehensive treatment of crush energy and how to develop structural stiffness properties from crash test data. Computer simulations are reviewed and discussed. Extensively revised, this edition contains new material on side pole impacts. It has entirely new chapters devoted to low-speed impacts, downloading electronic data from vehicles, deriving structural stiffness in side impacts, and incorporating electronic data into accident reconstructions
