Book Description
Light rail trains (LRT) are an important part of public transport but due to perceived high life-cycle costs are not always considered suitable. Life cycle cost reduction might be achieved through a knowledge-based maintenance management rather than just on experience. This work develops limits of maintenance and renewal of LRT systems based on vehicle reactions to the current track quality through measured data, multibody simulations and track geometry indices. An approach based on knowledge would lead to a track condition which allows a safe, comfortable, and under an appropriate maintenance strategy, economically profitable operation.

Book Description
This book reports on the 13th International Workshop on Railway Noise (IWRN13), held on September 16-20, 2019, in Ghent, Belgium. It gathers original peer-reviewed papers describing the latest developments in railway noise and vibration, as well as state-of-the-art reviews written by authoritative experts in the field. The different papers cover a broad range of railway noise and vibration topics, such as rolling noise, wheel squeal, noise perception, prediction methods, measurements and monitoring, and vehicle interior noise. Further topics include rail roughness, rail corrugation and grinding, high-speed rail and aerodynamic noise, structure-borne noise, ground-borne noise and vibration, and resilient track forms. Policy, criteria and regulation are also discussed. Offering extensive and timely information to both scientists and engineers, this book will help them in their daily efforts to identify, understand and solve problems related to railway noise and vibration, and to achieve the ultimate goal of reducing the environmental impact of railway systems.

Book Description
In many countries, the development of railway science is of great significance to both the economy and society, and transdisciplinary studies involving railways and other fields has also become more important in recent years. This book presents the proceedings of the 7th International Symposium on Innovation & Sustainability of Modern Railway (ISMR 2020), held in Nanchang, China from 23 - 25 October 2020. The symposium has been held biennially since 2008 and is principally aimed at expanding the scientific partnership between Russian and Chinese transport universities in the field of railway transportation. It is organized in a collaboration between the Federal Railway Transport Agency, Irkutsk State Transport University (IrGUPS) and East China Jiaotong University, and enables scientists from Russia, China and Mongolia to come together to discuss breakthrough technologies, as well as the problems of innovation in the secure operation of modern railways. Despite the disruption caused by the global pandemic, 89 submissions were received for the 2020 edition, 38 of which were selected after review for presentation and publication here. These comprise 12 papers dealing with railways and mechanics, 20 covering railways and computer sciences, and 6 related to railways and management, together with the 2 contributions of the invited keynote speakers (professor Xiaoyan Lei, principle of East China Jiaotong University, and professor Erol Guler from George Mason University). The book provides an insight into new ideas and developments in the industry, and will be of interest to all railway practitioners.

Book Description
This book systematically presents the theory, numerical implementation, field experiments and practical engineering applications of the ‘Vehicle–Track Coupled Dynamics’. Representing a radical departure from classic vehicle system dynamics and track dynamics, the vehicle–track coupled dynamics theory considers the vehicle and track as one interactive and integrated system coupled through wheel–rail interaction. This new theory enables a more comprehensive and accurate solution to the train–track dynamic interaction problem which is a fundamental and important research topic in railway transportation system, especially for the rapidly developed high-speed and heavy-haul railways. It has been widely applied in practical railway engineering. Dr. Wanming Zhai is a Chair Professor of Railway Engineering at Southwest Jiaotong University, where he is also chairman of the Academic Committee and Director of the Train and Track Research Institute. He is a member of the Chinese Academy of Sciences and one of the leading scientists in railway system dynamics. Professor Zhai is Editor-in-Chief of both the International Journal of Rail Transportation, published by Taylor & Francis Group, and the Journal of Modern Transportation, published by Springer. In addition, he is a trustee of the International Association for Vehicle System Dynamics, Vice President of the Chinese Society of Theoretical and Applied Mechanics, and Vice President of the Chinese Society for Vibration Engineering. /div

Book Description
Railways are an environmentally friendly means of transport well suited to modern society. However, noise and vibration are key obstacles to further development of the railway networks for high-speed intercity traffic, for freight and for suburban metros and light-rail. All too often noise problems are dealt with inefficiently due to lack of understanding of the problem. This book brings together coverage of the theory of railway noise and vibration with practical applications of noise control technology at source to solve noise and vibration problems from railways. Each source of noise and vibration is described in a systematic way: rolling noise, curve squeal, bridge noise, aerodynamic noise, ground vibration and ground-borne noise, and vehicle interior noise. - Theoretical modelling approaches are introduced for each source in a tutorial fashion - Practical applications of noise control technology are presented using the theoretical models - Extensive examples of application to noise reduction techniques are included Railway Noise and Vibration is a hard-working reference and will be invaluable to all who have to deal with noise and vibration from railways, whether working in the industry or in consultancy or academic research. David Thompson is Professor of Railway Noise and Vibration at the Institute of Sound and Vibration Research, University of Southampton. He has worked in the field of railway noise since 1980, with British Rail Research in Derby, UK, and TNO Institute of Applied Physics in the Netherlands before moving to Southampton in 1996. He was responsible for developing the TWINS software for predicting rolling noise. - Discusses fully the theoretical background and practical workings of railway noise - Includes the latest research findings, brought together in one place - Forms an extended case study in the application of noise control techniques

Book Description
This is a thorough revision and updating of the extremely successful third edition. As in previous editions, the following three perspectives are considered in depth: experimental cognitive psychology; cognitive science, with its focus on cognitive modelling; and cognitive neuropsychology with its focus on cognition following brain damage. In addition, and new to this edition, is detailed discussion of the cognitive neuroscience perspective, which uses advanced brain-scanning techniques to clarify the functioning of the human brain. There is detailed coverage of the dynamic impact of these four perspectives on the main areas of cognitive psychology, including perception, attention, memory, knowledge representation, categorisation, language, problem-solving, reasoning, and judgement. The aim is to provide comprehensive coverage that is up-to-date, authoritative, and accessible. All existing chapters have been extensively revised and re-organised. Some of the topics receiving much greater coverage in this edition are: brain structures in perception, visual attention, implicit learning, brain structures in memory, prospective memory, exemplar theories of categorisation, language comprehension, connectionist models in perception, neuroscience studies of thinking, judgement, and decision making. Cognitive Psychology: A Students Handbookwill be essential reading for undergraduate students of psychology. It will also be of interest to students taking related courses in computer science, education, linguistics, physiology, and medicine.
