Performance-Based Gear Metrology

Performance-Based Gear Metrology

William D. Mark

Wiley-Blackwell
2012
sidottu
A mathematically rigorous explanation of how manufacturing deviations and damage on the working surfaces of gear teeth cause transmission-error contributions to vibration excitations Some gear-tooth working-surface manufacturing deviations of significant amplitude cause negligible vibration excitation and noise, yet others of minuscule amplitude are a source of significant vibration excitation and noise. Presently available computer-numerically-controlled dedicated gear metrology equipment can measure such error patterns on a gear in a few hours in sufficient detail to enable accurate computation and diagnosis of the resultant transmission-error vibration excitation. How to efficiently measure such working-surface deviations, compute from these measurements the resultant transmission-error vibration excitation, and diagnose the manufacturing source of the deviations, is the subject of this book. Use of the technology in this book will allow quality spot checks to be made on gears being manufactured in a production run, to avoid undesirable vibration or noise excitation by the manufactured gears. Furthermore, those working in academia and industry needing a full mathematical understanding of the relationships between tooth working-surface deviations and the vibration excitations caused by these deviations will find the book indispensable for applications pertaining to both gear-quality and gear-health monitoring. Key features: Provides a very efficient method for measuring parallel-axis helical or spur gears in sufficient detail to enable accurate computation of transmission-error contributions from working-surface deviations, and algorithms required to carry out these computations, including examplesProvides algorithms for computing the working-surface deviations causing any user-identified tone, such as ‘ghost tones,’ or ‘sidebands’ of the tooth-meshing harmonics, enabling diagnosis of their manufacturing causes, including examplesProvides explanations of all harmonics observed in gear-caused vibration and noise spectra.Enables generation of three-dimensional displays and detailed numerical descriptions of all measured and computed working-surface deviations, including examples

Staging Romantic Chameleons and Imposters

Staging Romantic Chameleons and Imposters

William D. Brewer

Palgrave Macmillan
2015
sidottu
Examining chameleonic identities as seen in theatrical performances and literary texts during the Romantic period, this study explores cultural attitudes toward imposture and how it reveals important and much-debated issues about this time period. Brewer shows chameleonism evoked anxieties about both social instability and British selfhood.

Genocide

Genocide

William D. Rubinstein

Routledge
2024
sidottu
Genocide is a topic beset by ambiguities over meaning and double standards. In this stimulating and gripping history, William Rubinstein sets out to clarify the meaning of the term genocide and its historical evolution, and provides a working definition that informs the rest of the book. He makes the important argument that each instance of genocide is best understood within a particular historical framework and provides an original chronology of these distinct frameworks. In the final part of the book he critically examines a number of alleged past and recent genocides: from native Americans, slavery, the Irish famine, homosexuals and gypsies in the Nazi concentration camps, Yugoslavia, Rwanda through to the claims of pro-lifers and anti-abortionists.

Shadow Pasts

Shadow Pasts

William D. Rubinstein

Routledge
2016
sidottu
For many intelligent people, the stuff of history does not consist of the kind of dry-as-dust investigations of diplomatic, economic, or political history that most university historians research and write about, but the famous topics of historys mysteries- who was Jack the Ripper? Was there a conspiracy to kill President Kennedy? Did Richard III murder the Princes in the Tower? What are the mysteries of the ancient Pyramids?Not only have a great many books and articles been written on these and similar topics by so-called amateur historians, but they have generated societies, conferences, newsletters, and television programmes. Many people who are not academic historians take a keen interest in these topics, and have in some cases made themselves real experts on them, with interesting theories of their own. Despite all of this, however, these topics are virtually ignored by academic historians and can be treated with contempt. In Shadow Pasts, William D. Rubinstein a well-known and widely published history professor, examines seven of the most famous and interesting topics which have been discussed, debated, examined, and written about by amateur historians. Each of these mysteries and the theories surrounding them are examined in detail, with Professor Rubinstein presenting his own original and sometimes surprising conclusions about what really happened.

Housing in Taiwan

Housing in Taiwan

William D.H. Li

Routledge
2019
sidottu
Published in 1998, in this book the author points out the inadequacies caused by the division between housing research on production and consumption, and the theoretical divide between structural and agent-centred approaches on housing. By developing an understanding of social relations within the structured process of housing provision, the author argues that action and the specific form of housing provision can be better understood. By using pre-sale housing in Taiwan as a positive example, the author shows how housing production and consumption are closely related and structured through agents' purposive interaction, and how agents are benefited through their relations.

Economics and Policy Issues in Climate Change

Economics and Policy Issues in Climate Change

William D. Nordhaus

CRC Press
2018
nidottu
Although the negotiation of the Kyoto Protocol focused world attention on the global climate, it was just one step in the ongoing process of addressing climate change in all its facets. Research by the UN's Intergovernmental Panel on Climate Change (IPCC) has been ongoing since 1988. An extensive IPCC Working Group report published in 1995 examined the economic and social aspects of climate change. In this volume, eminent analysts assess that IPCC report and address the questions that emerge from it. The result is an instructive and cogent look at the realities of climate change and some methods (and difficulties) of dealing with them. William Nordhaus's introduction establishes the context for the book. It provides basic scientific background on climate change, reviews the IPCC's activities, and explains the genesis of the analyses. Subsequent contributions fall into two categories. Early chapters review analytical issues critical to social and economic understanding of climate change. A second set of chapters address specific economic questions surrounding climate-change policy. The result is an original and significant contribution to the evolving debate on this crucial hot-button topic.
