Are you a non-native English speaker? Are you often confronted with manuscript rejections because of poor language impeding comprehension of your paper? A Practical Guide to Scientific and Technical Translation is your solution. In this one-stop guide, two authors with extensive experience as reviewers and translators in a vast medley of scientific fields assist you to produce professional quality documents, whether through direct authoring in a language foreign to you or translation from an existing text. The book is not intended as a text on English grammar but as a troubleshooting guide to linguistic and style errors. We will help you overcome at least the most common problems here. Technical terminology searching and choice will also be covered with examples from a number of scientific (physics, chemistry) and engineering disciplines (aviation, transport, nuclear, environment, etc.), with advice on how to choose the right term for the right job. While the emphasis is on producing documents in English (the lingua franca of modern scientific literature), general translation concepts are also discussed. Hence, this book will also be useful to translators, and scientists who need to present their work in languages other than English.

This book presents selected topics in implementing a risk-based approach for complex engineering systems in general, and nuclear plants in particular. It addresses gap areas in implementing the risk-based approach to design, operation and regulation, covering materials reliability, digital system reliability, software reliability, human factor considerations, condition monitoring and prognosis, structural aspects in risk-based design as well as the application aspects like asset management for first-of-their-kind projects, strategic management and other academic aspect. Chapters are authored by renowned experts who address some of the identified challenges in implementation of risk-based approach in a clear and cogent manner, using illustrations, tables and photographs for ease of communication. This book will prove useful to researchers, professionals, and students alike.

This thesis provides an innovative strategy for rail crack monitoring using the acoustic emission (AE) technique. The field study presented is a significant improvement on laboratory studies in the literature in terms of complex rail profile and crack conditions as well as high operational noise. AE waves induced by crack propagation, crack closure, wheel-rail impact and operational noise were obtained through a series of laboratory and field tests, and analyzed by wavelet transform (WT) and synchrosqueezed wavelet transform (SWT). A wavelet power-based index and the enhanced SWT scalogram were sequentially proposed to classify AE waves induced by different mechanisms according to their energy distributions in the time–frequency domain. A novel crack sizing method taking advantage of crack closure-induced AE waves was developed based on fatigue tests in the laboratory. The propagation characteristics of AE waves in the rail were investigated, and Tsallis synchrosqueezed wavelet entropy (TSWE) with time was finally brought forward to detect and locate rail cracks in the field. The proposed strategy for detection, location and sizing of rail cracks helps to ensure the safe and smooth operation of the railway system. This thesis is of interest to graduate students, researchers and practitioners in the area of structural health monitoring.
