This book was released on 2012-12-06 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the most sophisticated fault diagnosis and condition monitoring systems have their origin in the aerospace and nuclear energy industries, their use is by no means restricted to such areas of 'high technology'. Modern machinery in most industrial plants is now so complex and expensive that mechanics find it increas ingly difficult to detect failure by, for instance, recognising changes in sound 'signatures', and few plants can afford the luxury of regular 'stripping down'. Increasingly, therefore, eady-warning devices are being employed in an effort to prevent catastrophic breakdown. This book provides the first co-ordinated compilation of fault diagnosis and con dition monitoring devices. It proceeds in three logical steps. The eady chapters deal with those conditions which contribute to deterioration and the consequent likely development of faults. The middle part of the book considers the various tech niques of monitoring and discusses the criteria for their selection in different situ ations. The final chapters provide a guide to the interpretation of the information signals deriving from monitoring, relating to reliability science and the mathematics of probability, and thus providing decision data on which management can act.
Download or read book Real time Condition Monitoring and Fault Diagnosis of Gear Train Systems Using Instantaneous Angular Speed IAS Analysis written by Abdulrahman S. Sait and published by . This book was released on 2013 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation presents a reliable technique for monitoring the condition of rotating machinery by applying instantaneous angular speed (IAS) analysis. A new analysis of the effects of changes in the orientation of the line of action and the pressure angle of the resultant force acting on gear tooth profile of spur gear under different levels of tooth damage is utilized. The analysis and experimental work discussed in this dissertation provide a clear understating of the effects of damage on the IAS by analyzing the digital signals output of rotary incremental optical encoder. A comprehensive literature review of state of the knowledge in condition monitoring and fault diagnostics of rotating machinery, including gearbox system is presented. Progress and new developments over the past 30 years in failure detection techniques of rotating machinery including engines, bearings and gearboxes are thoroughly reviewed. This work is limited to the analysis of a gear train system with gear tooth surface faults utilizing angular motion analysis technique. Angular motion data were acquired using an incremental optical encoder. Results are compared to a vibration-based technique. The vibration data were acquired using an accelerometer. The signals were obtained and analyzed in the phase domains using signal averaging to determine the existence and position of faults on the gear train system. Forces between the mating teeth surfaces are analyzed and simulated to validate the influence of the presence of damage on the pressure angle and the IAS. National Instruments hardware is used and NI LabVIEW software code is developed for real-time, online condition monitoring systems and fault detection techniques. The sensitivity of optical encoders to gear fault detection techniques is experimentally investigated by applying IAS analysis under different gear damage levels and different operating conditions. A reliable methodology is developed for selecting appropriate testing/operating conditions of a rotating system to generate an alarm system for damage detection.

Download or read book A Historical Review and Analysis of Army Physical Readiness Training and Assessment written by Whitfield East and published by CreateSpace. This book was released on 2013-12 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Drillmaster of Valley Forge-Baron Von Steuben-correctly noted in his "Blue Book" how physical conditioning and health (which he found woefully missing when he joined Washington's camp) would always be directly linked to individual and unit discipline, courage in the fight, and victory on the battlefield. That remains true today. Even an amateur historian, choosing any study on the performance of units in combat, quickly discovers how the levels of conditioning and physical performance of Soldiers is directly proportional to success or failure in the field. In this monograph, Dr. Whitfield "Chip" East provides a pragmatic history of physical readiness training in our Army. He tells us we initially mirrored the professional Armies of Europe as they prepared their forces for war on the continent. Then he introduces us to some master trainers, and shows us how they initiated an American brand of physical conditioning when our forces were found lacking in the early wars of the last century. Finally, he shows us how we have and must incorporate science (even when there exists considerable debate!) to contribute to what we do-and how we do it-in shaping today's Army. Dr. East provides the history, the analysis, and the pragmatism, and all of it is geared to understanding how our Army has and must train Soldiers for the physical demands of combat. Our culture is becoming increasingly ''unfit," due to poor nutrition, a lack of adequate and formal exercise, and too much technology. Still, the Soldiers who come to our Army from our society will be asked to fight in increasingly complex and demanding conflicts, and they must be prepared through new, unique, and scientifically based techniques. So while Dr. East's monograph is a fascinating history, it is also a required call for all leaders to better understand the science and the art of physical preparation for the battlefield. It was and is important for us to get this area of training right, because getting it right means a better chance for success in combat.

Available in PDF, EPUB and Kindle. Book excerpt: It is often said that the practice of management is in crisis, and that managers are now finding it harder than ever to develop strategies which withstand the shocks of the marketplace. This illuminating book cuts through these conflicting issues to show how organizational communication plays a vital role in confronting uncertainty. Arguing that many managers fail to adequately consider the communication consequences of the decision making process and its impact on organizational effectiveness, Hargie and Tourish present here numerous organizational communication insights, and show how they reveal a way through these dilemmas. Based on cutting-edge research findings and case studies, this book features contributions from the UK, USA, Canada, New Zealand and Norway, bringing multiple perspectives to this topical subject. The result is a comprehensive guide to organizational communication useful for managers, academics and students.
Download or read book Understanding Public Policy written by Paul Cairney and published by Bloomsbury Publishing. This book was released on 2019-11-08 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fully revised second edition of this textbook offers a comprehensive introduction to theories of public policy and policymaking. The policy process is complex: it contains hundreds of people and organisations from various levels and types of government, from agencies, quasi- and non-governmental organisations, interest groups and the private and voluntary sectors. This book sets out the major concepts and theories that are vital for making sense of the complexity of public policy, and explores how to combine their insights when seeking to explain the policy process. While a wide range of topics are covered – from multi-level governance and punctuated equilibrium theory to 'Multiple Streams' analysis and feminist institutionalism – this engaging text draws out the common themes among the variety of studies considered and tackles three key questions: what is the story of each theory (or multiple theories); what does policy theory tell us about issues like 'evidence based policymaking'; and how 'universal' are policy theories designed in the Global North? This book is the perfect companion for undergraduate and postgraduate students studying public policy, whether focussed on theory, analysis or the policy process, and it is essential reading for all those on MPP or MPM programmes. New to this Edition: - New sections on power, feminist institutionalism, the institutional analysis and development framework, the narrative policy framework, social construction and policy design - A consideration of policy studies in relation to the Global South in an updated concluding chapter - More coverage of policy formulation and tools, the psychology of policymaking and complexity theory - Engaging discussions of punctuated equilibrium, the advocacy coalition framework and multiple streams analysis
