This book discusses the features of composite materials and arch structures. Providing an in-depth fundamental and practical guide to the field, it systemically addresses all aspects of concrete-filled steel tubular (CFST) arch bridges, including a comprehensive overview on technical developments, structural systems, structural detailing, design and analysis, construction technology, and maintenance. The real-world examples presented have been carefully selected to highlight the advanced t...

This book presents a newly designed dynamic fluidic sprinkler (DFS) to improve hydraulic performance of the existing complete fluidic sprinkler (CFS) under low-pressure conditions. Sprinkler irrigation has high prospects for improving water management in crop production. In recent years, low-pressure water-saving has become an important research content in the field of sprinkler irrigation. It introduces the effect of riser height on rotation uniformity and application rate of the dynamic ...

This book focuses on the deep learning technologies and their applications in the catenary detection of high-speed railways. As the only source of power for high-speed trains, the catenary's service performance directly affects the safe operation of high-speed railways. This book systematically shows the latest research results of catenary detection in high-speed railways, especially the detection of catenary support component defect and fault. Some methods or algorithms have been adopted ...

This book investigates in detail the generalized principle of the pattern multiplication (GPPM) and its application to new phased array with high performances. It introduces the generalized element factor (GEF) to small aperture with multi-modes. Based on the GEF, the GPPM can be used to construct the wide-angle scanning array with the dual-port phase mode antenna. Further, a dual-port phase mode SSPPs antenna is proposed to scan in 3D free space. It is extended to two kinds of 1D arrays w...

This book covers multifaceted aspects of arch structures, addressing their technical, scientific, historical, social, and cultural dimensions, while also exploring future perspectives and challenges. It encompasses a broad range of structures, from historic examples to contemporary designs and the latest innovations, offering insights into cutting-edge solutions and visionary concepts. The proceedings of ARCH 2023 are aimed at scientists, designers, engineers, stakeholders, and contractors...

This volume is dedicated entirely to arch structures' related issues, namely technical, scientific, historical, social, and cultural as well as future perspectives and challenges. Covered subjects are related to various structures: from historical ones, through those designed and constructed contemporarily, up to the latest and forthcoming solutions as well as to innovative concepts and visions. The proceedings of ARCH 2023 are addressed to all those who deal with arch bridge structures: s...
