NDE Handbook
NDE Handbook: Non-Destructive Examination Methods for Condition Monitoring deals with monitoring of equipment, structures, and pipes in mechanical engineering, in the processing industry, in construction, and in electrotechnical fields. The book explains acoustic cross correlation involving leak detection in buried main water pipes or heating pipes by using special instruments to detect the flow noise generated at the point of fracture. The acoustic emission method, based on collection of vibrations or sound waves from the suspected material, can detect changes occurring in the material. Magnetic methods and eddy currents can measure the thickness of the coating on specific materials; dye penetrants can expose cracks or cleavages in surface materials; and emission spectroscopy can identify or sort the chemical composition of steel. The book also describes an endoscope used to visualize the interior of objects and the electrical resistance probe that can measure the loss of material based on changes in the electrical resistance. Other NDE methods that are used by investigators include stress pattern analysis by thermal emission, pulsed video thermography, Moire contour mapping, holographic interferometry, computerized tomography, and positron annihilation. The book will prove valuable for engineers, physicists, technicians, operators involved in material research, risk prevention, or accident control, and for general readers interested in materials quality and specifications.
Handbook of Nondestructive Evaluation 4.0
This handbook, now as second edition, continues to comprehensively cover the cutting-edge trends and techniques essential for the integration of nondestructive evaluation (NDE) into the changing face of the modern industrial landscape. In particular, it delves into the marriage of NDE with new techniques in e.g. data mining and management, cloud computing, autonomous operation, AI for data analysis and decision making, as well as cyber security, highlighting the potential for cyber-physical controlled production and discussing the myriad possible applications across many different industries. The Handbook of NDE 4.0 centers around the Industry 4.0 philosophy – the next generation of industrial production encompassing all aspects of networking across all industrial areas. It discusses the adaptation of existing NDE techniques to emerging new technological areas, such as 3D printing, via the introduction of cyber systems into the inspection and maintenance processes. In addition, the handbook covers topics such as the management and processing of big data with respect to real-time monitoring of structural integrity and reliable inspection of individual components. Remote NDE to include competence not available on-site will be a potential technique to increase reliability of NDE inspections by integrating additional specialist inputs into the decision process by methods such as telepresence, thereby better leveraging the scarce resources of senior inspectors into industrial inspections at multiple sites. The handbook also includes non-technical topics of direct relevance to leadership, management, and adoption of this new philosophy. The handbook houses a wealth of essential information to help academics, industry professionals, regulatory bodies, and entrepreneurs navigate through this burgeoning new field. The material in this handbook is presented with the intention of ultimately improving human safety through reliable inspections and dependable maintenance of critical infrastructure, while also enhancing business value through reduced downtime, affordable maintenance, and talent optimization. The content is positioned to inspire NDE professionals to think broadly in terms of their role as continuous value add rather than discrete decision support. This second edition contains many new chapters, and half of all chapters were revised from the 1st edition, based on the engagement of authors through global platforms such as the ICDNT Specialist International Group on NDE 4.0 and the International conference series on NDE 4.0.
The Handbook of Near-Death Experiences
Author: Bruce Greyson
language: en
Publisher: Bloomsbury Publishing USA
Release Date: 2009-06-22
A team of international experts presents the history, recent developments, and controversies in the intriguing study of near-death experience. Experts from around the world share the history and current state of near-death experience (NDE) knowledge. They explore controversies in the field, offer stories from their research, and express their hopes for the future of investigation into this fascinating phenomenon. As modern medical techniques for resuscitation advance, NDEs are more frequently reported. These include more than the popular notions of moving through a tunnel or seeing a light. They also include people, once revived, knowing things their knowledge of which can't currently be explained. As The Handbook of Near-Death Experiences: Thirty Years of Investigation makes clear, great controversy exists in the medical and psychological fields concerning NDEs. Are they caused by physiological changes in the brain, or are they biological reactions to oxygen loss or impending death? Are they a product of changing states of consciousness? Or are they caused by something else altogether? All of these ideas and more are discussed in this unique and comprehensive volume.
