This book is the CNPC Economics & Technology Research Institute (referred to as CNPC ETRI) annual report since 2008 tracking and analyzing the development of the global oil and gas industry. Organized by a group of experts and research professionals, it dissects major events and hot topics to form an understanding and judgment of the industry’s development trends. It is rooted in China with a global perspective and serves as a valuable reference for both industry insiders and outsiders to ...

This book presents the melt pool monitored-laser additive manufacturing (MPMed-LAM) technology for enhancing forming quality and mechanical performance of key metalic components. Despite progress in metal additive manufacturing (AM) since the 1970s, a large number of challenges remain in synergic controlling both shape and performance due to thermal stress-induced defects and metallurgical flaws. The book reviews key research on melt pool monitoring, forming quality control, microstructure...

This book introduces the laser hybrid additive manufacturing technology (LHAM) with alternately thermal and mechanical effects for the high-performance manufacturing of key components. Metal additive manufacturing (AM) technologies have made considerable progress in the basic theoretical field since its invention in the 1970s. However, there are still some difficulties in the coordinated control of the structure and performance, containing the challenges of “structure control” against defo...

This book introduces the fundamentals of laser shock peening (LSP) and its effects on the corrosion behaviours of metal alloy materials. It focuses on innovations in theory and methods related to LSP-induced surface nanocrystallization and corrosion resistance in steels, Mg alloy and titanium alloy. The main contents of the book include the characteristics of laser shock wave, LSP-induced surface integrity and the anti-corrosion mechanism. The research has accumulated a large amount of exp...

Laser shock processing (LSP) is a new and promising surface treatment technique for improving the fatigue durability, corrosion, wear resistance and other mechanical properties of metals and alloys. During LSP, the generated shock wave can introduce a deep compressive residual stress into the material, due to its high-pressure (GPa-TPa), ultra-fast (several tens nanoseconds), ultra-high strain-rate and high-energy. The overall properties and behavior of metal materials subjected to LSP wer...

An uncoded multimedia transmission (UMT) system is one that skips quantization and entropy coding in compression and all subsequent binary operations, including channel coding and bit-to-symbol mapping of modulation. By directly transmitting non-binary symbols with amplitude modulation, the uncoded system avoids the annoying cliff effect observed in the coded transmission system. This advantage makes uncoded transmission more suited to both unicast in varying channel conditions and multica...

Evidence-based Clinical Chinese Medicine provides a 'whole evidence' analysis of the Chinese medicine management of allergic rhinitis. Evidence from the classical Chinese medicine literature, contemporary clinical literature, and the outcomes of clinical trials and experimental studies are reviewed, analysed and synthesized. The data from all these sources are condensed to provide evidence-based statements which will inform clinical practice and guide future research.This book has been des...

This book addresses the most pressing and current work-life issues that are impacting Equity, Diversity, and Inclusion (EDI) in organisations across the Asia-Pacific. It is organised around three major themes: (1) Work-life equality and justice; (2) Technology, work, and family; and (3) Work-life values and trends in Asia, all of which will be discussed in relation to EDI.Issues concerning the work-life interface are closely intertwined with issues relating to EDI—for example, labo...

Coming to work sick may do more harm than staying home - for the employee, the team, and the firm. Whilst the cost of absenteeism in organizations has been widely acknowledged and extensively examined, the counter-issue of 'presenteeism' has only recently attracted scholarly attention as a phenomenon that harms employee wellbeing, disrupts team dynamism, and damages productivity. This volume brings together leading international scholars from diverse scientific backgrounds, including occup...

50 years ago by Changsha hijio Ko (thieves) unearthed the Warring States silk manuscripts, recorded a peculiar position of the tomb of the Warring States period, after 50 years, which the grandson of a soil master in his notes found the secret, gathered a group of experienced the thieves went to hunt, who would have thought, this tomb unexpectedly has so many strange things: seven suspected coffin, green eye fox corpse, Hydra Bai. Who is this mysterious tomb, they really can not find a rea...
