Download or read book Geometric Design of Linkages written by J. Michael McCarthy and published by Springer Science & Business Media. This book was released on 2010-11-11 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an introduction to the mathematical theory of design for articulated mechanical systems known as linkages. The focus is on sizing mechanical constraints that guide the movement of a work piece, or end-effector, of the system. The function of the device is prescribed as a set of positions to be reachable by the end-effector; and the mechanical constraints are formed by joints that limit relative movement. The goal is to find all the devices that can achieve a specific task. Formulated in this way the design problem is purely geometric in character. Robot manipulators, walking machines, and mechanical hands are examples of articulated mechanical systems that rely on simple mechanical constraints to provide a complex workspace for the end- effector. The principles presented in this book form the foundation for a design theory for these devices. The emphasis, however, is on articulated systems with fewer degrees of freedom than that of the typical robotic system, and therefore, less complexity. This book will be useful to mathematics, engineering and computer science departments teaching courses on mathematical modeling of robotics and other articulated mechanical systems. This new edition includes research results of the past decade on the synthesis of multi loop planar and spherical linkages, and the use of homotopy methods and Clifford algebras in the synthesis of spatial serial chains. One new chapter on the synthesis of spatial serial chains introduces numerical homotopy and the linear product decomposition of polynomial systems. The second new chapter introduces the Clifford algebra formulation of the kinematics equations of serial chain robots. Examples are use throughout to demonstrate the theory.
Download or read book Organizational Linkages written by National Research Council and published by National Academies Press. This book was released on 1994-02-01 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: By one analysis, a 12 percent annual increase in data processing budgets for U.S. corporations has yielded annual productivity gains of less than 2 percent. Why? This timely book provides some insights by exploring the linkages among individual, group, and organizational productivity. The authors examine how to translate workers' productivity increases into gains for the entire organization, and discuss why huge investments in automation and other innovations have failed to boost productivity. Leading experts explore how processes such as problem solving prompt changes in productivity and how inertia and other characteristics of organizations stall productivity. The book examines problems in productivity measurement and presents solutions. Also examined in this useful book are linkage issues in the fields of software engineering and computer-aided design and why organizational downsizing has not resulted in commensurate productivity gains. Important theoretical and practical implications contribute to this volume's usefulness to business and technology managers, human resources specialists, policymakers, and researchers.

Download or read book Design of Special Planar Linkages written by Jingshan Zhao and published by Springer Science & Business Media. This book was released on 2013-08-31 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Planar linkages play a very important role in mechanical engineering. As the simplest closed chain mechanisms, planar four-bar linkages are widely used in mechanical engineering, civil engineering and aerospace engineering. Design of Special Planar Linkages proposes a uniform design theory for planar four-bar linkages. The merit of the method proposed in this book is that it allows engineers to directly obtain accurate results when there are such solutions for the specified n precise positions; otherwise, the best approximate solutions will be found. This book discusses the kinematics and reachable workspace and singularity of a planar 3-RRR linkage, which can be used to analyze other planar linkages. Then a foldable stair that retains the walking conversions of human beings and all the merits of a concrete stair in civil engineering is described along with a lifting guidance mechanism that has the advantages of high strength, high rigidity, lightweight overconstraint trusses and motion flexibility. The method proposed in this book can be applied to other planar linkages. This book offers a valuable resource for scientists, researchers, engineers, graduate students in mechanical engineering especially those interested in engineering design, robotics and automation.

Book excerpt: Uranium industry occupies a very important place in the socio-economic sphere of East Singhbhum District of Jharkhand ever since its inception in 1967 it has played an important role in influencing health, education, crime, employment, income, migration & displacement and environment of the people of surrounding area. The industry has situated at Jaduguda, which falls under Mushabani and Potka Block of East Singhbhum District of Jharkhand. The socio-economic life of the people residing in and around this area has influenced by this in Jaduguda. The findings are based on a comparison of data on variables like health, education, crime, employment, income, migration & displacement and environment prior to inception of the mines and the situation at present time. It has observed that there has been positive impact on education employment and income. However, the study also observed there are certain negative linkages also. The important one is being deterioration of the health of the people, environmental degradation, and increasing rate of crime, migration & displacement. This study provides a means of identifying and tracking indicators associated with community vitality in Jaduguda communities that relate to the uranium mining industry including approaches that assess community health (physical, mental/emotional, spiritual/cultural, and social), community quality of life, community sustainable development, and community wellness as such, it has undertaken a broad array of studies since its inception, guided by input from community members from Jaduguda. As such, the purpose of the study is to identify the socio-economic linkages both beneficial and otherwise that the modern uranium mining industry has had on Jaduguda, and its residents and communities.

This book was released on 1980 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the period 1970-80, nearly 10,000 jobs were created in the industrial estates of Malacca. However, multinational import-export firms in the Free Trade Zones dominate the industrialization process, and whatever advantageous regional effects there may be are limited. The conclusion reached in this paper is that spin-offs benefitting other rmanufacturing industries are more obviously felt in the Klang Valley Metropolitan Area outside Malacca than in the state itself.

This book was released on 2020-05-11 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume picks up from where a previously edited title in this book series - Rural-Urban Linkages and Sustainable Development in Africa (2018) left off, by presenting nine new case studies from various parts of the African continent. These cases illustrate the complex and multifaceted interactions between cities and rural areas, through the flow of resources, people, capital, information, and goods which directly impact the sustainable development of these concerned areas. Contributions are drawn from young faculty and graduates from the three master’s programmes in Sustainable Urban Development, Sustainable Integrated Rural Development and Mining and Mineral Resources, coordinated by the eight partner African universities who make up the Education for Sustainable Development in Africa (ESDA) initiative. The volume is part of the ESDA book series that serves primarily as undergraduate and graduate instruction materials for courses on sustainable development in Africa. It also aims to inform policy initiatives on development issues on the continent.

Download or read book Trade Linkages and International Business Cycle Comovement Evidence from Korean Industry Data written by Dongyeol Lee and published by International Monetary Fund. This book was released on 2019-05-24 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: Through the 2000s, Korea’s export and import linkages to advanced and emerging markets increased significantly. At the same time, the correlation of output growth between Korea and these economies rose. This paper investigates the nature of the link between trade linkages and the comovement of international business cycles (BC) using Korean industry-level domestic and international input-output data. The results suggest that, at the industry-level, higher export linkages lead to a larger positive GDP growth comovement, while higher import linkages lead to higher negative employment growth comovement. Furthermore, the decomposition of aggregate BC comovement shows that the increase in trade with China has contributed the most to aggregate BC comovement, while the impact of trade linkages on BC comovement is propagated domestically via vertical linkages. These findings suggest that the Korean economy can be significantly affected by a few countries that are highly linked through trade to Korea and/or a few industries that are highly interconnected to other industries.

Download or read book Special Aging Populations and Systems Linkages written by M. Joanna Mellor and published by Psychology Press. This book was released on 1996 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Special Aging Populations and Systems Linkages educates professionals working in geriatric settings about the needs and issues of several emerging special groups within today's aging population. It gives readers examples, guidelines, and a theoretical framework for developing successful linkages between aging and non-aging service systems to meet the service needs of these special populations. By exploring the challenges and barriers faced by service systems attempting to work together, Special Aging Populations and Systems Linkages provides a blueprint to those working with cross-system interest groups, task forces, and councils. The book informs readers of the epidemiology, issues, and concerns of some specific populations of older persons including: persons with developmental disabilities alcohol and substance abusers cancer patients persons with HIV/AIDS the abused elderly older caregivers Chapters in this timely book provide treatment experiences with these special populations and with linking systems as case histories for the professional. These case histories help social workers understand the needs of special older people with whom they work and facilitate negotiations among service systems and agencies so that older people facing special challenges secure the help they and their families need. Special Aging Populations and Systems Linkages asserts the absolute imperative for social workers and other geriatric professionals to understand the subpopulations which make up the 65-plus cohort in the U.S. and fosters creative thinking about service organization and practice issues generated by the diversity of this population. Students at all levels of gerontology programs; staff in the aging network (service personnel, administrators, and senior center directors); community service personnel; staff of Area Agencies on Aging; social workers in geriatric health care settings; public health educators; and social workers in service agencies for each of the special populations--mental retardation/developmental disabilities, cancer care, HIV/AIDS, substance abuse, adult protective services, child welfare--can refer to Special Aging Populations and Systems Linkages for insight time and again as they strive to meet the diverse needs of the entire aging population.
