Book Description
En este trabajo se han analizado por separado los elementos que definen el problema de sintesis dimensional óptima de mecanismos planos para generacion de trayectoria. Se ha contribuido a la normalización de proposición de funciones objetivo mediante el enunciado de requisitos que deben cumplir. Se ha propuesto la comparación geométrica de las curvas como función objetivo y se han elaborado métodos discretos. Asimismo se ha utilizado un método de optimización combinado exhaustivo-gradiante que, unido a la aplicación de tecnicas de reducción del espacio de diseño, permite abordar la busqueda del optimo global dentro del espacio de diseño de una manera robusta. Se ha probado la validez del metodo mediante su aplicación práctica en la sintesis de mecanismos reales.

Publisher:
ISBN:
Category : Business & Economics
Languages : en
Pages : 174

Book Description
The Government and authorities in Brazil were faced with a tragic accident in Goiânia resulting from the misuse of a strongly radioactive medical teletherapy source not under radiation protection surveillance. The present report is divided into four parts: a chronology of destruction of the source, discovery of the accident and initial response; a description of the human consequences and the dosimetry and treatment of seriously exposed and contaminated persons; an account of the assessment of the environmental contamination and the remedial actions taken; and observations and recommendations. Appendices and annexes give an assessment of the effectiveness of international co-operation in the emergency response, and provide further information on: public communications; radiological survey equipment; guidelines for the discharge of patients; radiological protection; chemical decontamination; and the lessons learned.

Defying Ocean's End

Defying Ocean's End PDF Author: Linda Glover
Publisher: Island Press
ISBN: 1597267511
Category : Nature
Languages : en
Pages : 308

Book Description
If humankind were given a mandate to do everything in our power to undermine the earth's functioning, we could hardly do a better job than we have in the past thirty years on the world's oceans, both by what we are putting into it-millions of tons of trash and toxic materials-and by what we are taking out of it-millions of tons of wildlife. Yet only recently have we begun to understand the scale of those impacts. Defying Ocean's End is the result of an unprecedented effort among the world's largest environmental organizations, scientists, the business community, media, and international governments to address these marine issues. In June 2003, in the culmination of a year-long effort, they met specifically to develop a comprehensive and achievable agenda to reverse the decline in health of the world's oceans. As conservation organizations begin to expand their focus from land issues to include a major focus on preservation of the sea, it is increasingly apparent that we have to approach marine conservation differently and at much larger scale than we have to date. What's also clear is the magnitude and immediacy of the growing ocean concerns are such that no one organization can handle the job alone. Defying Ocean's End is a bold step in bringing the resources needed to bear on this vast problem before it is too late. It offers a broad strategy, a practical plan with priorities and costs, aimed at mobilizing the forces needed to bring about a "sea change" of favorable attitudes, actions, and outcomes for the oceans-and for all of us.

Pages : 294

Book Description
This book offers a radical critique of mainstream, Marxist and feminist economic theories, ranging from the classical liberal economics of the eighteenth and nineteenth centuries to the feminist debates about domestic labour and patriarchy in the late twentieth century. It explores the increasing importance of household care relations, especially childcare, in shaping the domestic labour process. Trends in household gender relations and working patterns in Britain are explored in the context of political ideas and policies regarding the state, the economy, gender and care.

The Development of Mature Walking

The Development of Mature Walking PDF Author: David Sutherland
Publisher: Cambridge University Press
ISBN: 9780521412216
Category : Medical
Languages : en
Pages : 248

Book Description
This important monograph summarizes a comprehensive study on the maturation of walking in normal children. Research, undertaken at one of the world's leading gait analysis centers, involved over 400 studies on a total of nearly 300 children in ten age-groups from one to seven years. Data are presented on anthropometric measurements; tests of developmental progress; time/distance parameters such as stride length and walking velocity; twelve joint angles on each side measured throughout the gait cycle; dynamic electromyography of phasic activity in seven lower-extremity muscle groups; and force measurements including vertical force, fore/aft shear, medial/lateral shear and torque. At each age, composite joint-angle graphs and time/distance parameters are brought together with film tracings of a representative child in that age group. In addition, advanced methods of statistical analysis have been applied to the joint-angle data to define prediction regions within which ninety-five percent of normal children should lie throughout the gait cycle. Finally, a "decision tree" is presented from which a fitted age can be inferred for a subject based on non-age-specific data gathered in a motion analysis lab. Practical applications are demonstrated in a chapter devoted to two case studies.
