Book Description
Compiling the expertise of nine pioneers of the field, Magnetic Bearings - Theory, Design, and Application to Rotating Machinery offers an encyclopedic study of this rapidly emerging field with a balanced blend of commercial and academic perspectives. Every element of the technology is examined in detail, beginning at the component level and proceeding through a thorough exposition of the design and performance of these systems. The book is organized in a logical fashion, starting with an overview of the technology and a survey of the range of applications. A background chapter then explains the central concepts of active magnetic bearings while avoiding a morass of technical details. From here, the reader continues to a meticulous, state-of-the-art exposition of the component technologies and the manner in which they are assembled to form the AMB/rotor system. These system models and performance objectives are then tied together through extensive discussions of control methods for both rigid and flexible rotors, including consideration of the problem of system dynamics identification. Supporting this, the issues of system reliability and fault management are discussed from several useful and complementary perspectives. At the end of the book, numerous special concepts and systems, including micro-scale bearings, self-bearing motors, and self-sensing bearings, are put forth as promising directions for new research and development. Newcomers to the field will find the material highly accessible while veteran practitioners will be impressed by the level of technical detail that emerges from a combination of sophisticated analysis and insights gleaned from many collective years of practical experience. An exhaustive, self-contained text on active magnetic bearing technology, this book should be a core reference for anyone seeking to understand or develop systems using magnetic bearings.

Book Description
Part of the fifth edition of the classic Rolling Bearing Analysis, this book examines bearing performance and service life for more complex loading, more extreme operating conditions, and higher-speed applications. Several topics are unique to this work, including mathematical relationships for internal load distribution under conditions of high speed, combined radial, axial, and moment loading, as well as the effects of various types of profiling. The authors also delve into the mathematical development of rolling element-raceway lubricant film thickness and contact friction, the stress-life method for calculating bearing fatigue, and the effects of shaft and supporting structure flexure on bearing loading and deflection.

Book Description
Bearings and Distances by Glenn Arbery, is a novel of comic ironies and tragic recurrences set in the "post-racial" moment of the American experiment. In the summer after Barack Obama's election, Hermia Watson, a scholar of black history, lures the famous (and famously irresponsible) Professor Braxton Forrest back to his hometown in Georgia, using his two daughters as unwitting hostages. Returning alone while his pious wife continues touring Italy, Forrest arrives to the tremblings of his abandoned past and a confrontation with the Furies he thought modernity had left behind. In the course of a few days, Hermia realizes what violent revelations she has begun to unleash about her former lover, her mother, and her own identity-but it is too late to stop what is coming to light. Arbery revisits the obsessions of the 20th century Southern renaissance in a work that satirizes misconceptions and shallow pieties but takes seriously the wisdom of the Southern literary tradition-and its classical antecedents.

Book Description
Journal bearings, which are used in all kinds of rotating machinery, do not only support static loads, such as the weight of rotors and load caused by transmitted torque of reduction gears, but are, in addition almost the only machine element that is able to suppress various exciting forces acting on the rotating shaft. As rotating machines have become large and multi-staged, while compactness, high speed, and high output have also been realized in recent years, not only has the bearing load increased, but also the magnitude and variety of exciting forces. Therefore, the role and importance of journal bearings have increased tremendous ly. In particular, for the design of rotating machines with low vibration levels and high reliability, knowledge of the exact characteristic data of bearings, and especial ly of the stiffness or spring coefficients and the damping coefficients of oil films in bearings, is essential. However, the amount of reliable data now applicable to practical design is limited. Through the activity of the Research Subcommittee on Dynamic Charac teristics of Journal Bearings and Their Applications (designated as PSC 28), estab lished and organized in June 1979 through May 1982 within the Japan Society of Mechanical Engineers (JSME), these coefficients, together with static characteris tics, have been calculated and also measured on a number of new test rigs.

Please note: This is a companion version & not the original book. Sample Book Insights: #1 The way Charlotte was killed by a shooter in Newtown, Connecticut, generated a lot of media attention, which caused some people who were personally affected by the death of a child or loved one to feel helplessly exposed and vulnerable. #2 Grief is often misunderstood, and cultural norms promote double standards that are often harmful to those grieving. Certain tragedies are deemed worthy, and others are not. Individual grief is discouraged, even scorned, beyond a brief period of time.

Book Description
This book addresses the background and significance of the factors potentially influencing the clinical and biological outcomes of metal-on-metal hip implants. Metal-on-metal bearings were introduced and evaluated as an alternative to other bearing couples, particularly metal-on-polyethylene, due to their enhanced wear resistance as determined in laboratory testing. Initially, reports of short-term clinical outcomes were favorable and an increasing number of metal-on-metal prostheses were implanted. Subsequently, isolated case findings describing adverse tissue responses around the articulation became the harbinger of an increasing number of reports describing pseudotumors and other significant lymphocytic-based responses associated with metal-on-metal prostheses. Questions have been raised as to whether this is an implant, design, or patient-specific response. The reasons why some patients have a negative biological response and pathology while others do not remain to be determined, but tens of thousands of patients in the US, the UK, and around the world are considered to be at risk. Leading researchers and clinicians describe the issues related to the nature of the biological and pathological responses and the protocols that should be followed to determine if an adverse response is occurring. This book is essential reading for researchers, engineers, and orthopaedic surgeons who are involved in the design, evaluation, and implantation of metal-on-metal prostheses.
