Guía práctica de elementos finitos en estática


Book Description

El Método de los Elementos Finitos (MEF) es sin duda una de las herramientas más utilizadas actualmente en el ámbito del análisis y diseño de sistemas mecánicos. Permite validar y optimizar diseños de forma rápida y versátil, reduciendo la necesidad de costosas campañas experimentales y ofreciendo al diseñador información muy valiosa sobre el comportamiento del sistema y la influencia que tienen en él aspectos como la geometría, el material, la naturaleza de las cargas, etc. Basado en la extensa experiencia de los autores tanto docente como investigadora y en trabajos para empresas, este libro muestra cómo emplear el método para estudiar problemas reales de diseño mecánico. Con un enfoque teórico-práctico, está dirigido a alumnos del Grado de Ingeniería Mecánica o del Grado de Ingeniería en Tecnologías Industriales con el objetivo de dotarles de las nociones básicas teóricas y prácticas a la hora de afrontar un análisis mecánico mediante este método. La guía se ha dividido en dos partes claramente diferenciadas: En la primera parte se explican los conceptos básicos del MEF, siempre desde un punto de vista eminentemente práctico y con numerosos ejemplos ilustrativos. En la segunda parte se presenta una serie de ejemplos de aplicación de análisis por Elementos Finitos de distintos sistemas mecánicos: rodamientos, rótulas, implantes dentales, uniones atornilladas, etc. Para cada caso se describe cuál el problema que debe resolverse y se explican las características del modelo que se ha desarrollado para lograr los resultados requeridos. Sobre la base de los conceptos presentados en la primera parte del libro, en cada ejemplo se discute sobre si el modelo debe ser tridimensional o bidimensional, qué tipo de elemento habrá que utilizar y cómo será la malla, cómo se aplicarán las cargas y las condiciones de contorno, si bastará con hacer un análisis lineal o será necesario uno no lineal, cuál será el nivel de precisión de los resultados según el modelo empleado y la naturaleza propia del problema. El fin de esta guía práctica es precisamente dotar al futuro analista de Elementos Finitos de los conocimientos necesarios para que sea capaz de desarrollar el mejor modelo para dar respuesta a un problema particular.







Without Criteria


Book Description

A Deleuzian reading of Whitehead and a Whiteheadian reading of Deleuze open the possibility of a critical aesthetics of contemporary culture. In Without Criteria, Steven Shaviro proposes and explores a philosophical fantasy: imagine a world in which Alfred North Whitehead takes the place of Martin Heidegger. What if Whitehead, instead of Heidegger, had set the agenda for postmodern thought? Heidegger asks, “Why is there something, rather than nothing?” Whitehead asks, “How is it that there is always something new?” In a world where everything from popular music to DNA is being sampled and recombined, argues Shaviro, Whitehead's question is the truly urgent one. Without Criteria is Shaviro's experiment in rethinking postmodern theory, especially the theory of aesthetics, from a point of view that hearkens back to Whitehead rather than Heidegger. In working through the ideas of Whitehead and Deleuze, Shaviro also appeals to Kant, arguing that certain aspects of Kant's thought pave the way for the philosophical “constructivism” embraced by both Whitehead and Deleuze. Kant, Whitehead, and Deleuze are not commonly grouped together, but the juxtaposition of them in Without Criteria helps to shed light on a variety of issues that are of concern to contemporary art and media practices.




Occupational Safety and Hygiene


Book Description

Occupational Safety and Hygiene presents selected papers from the International Symposium on Occupational Safety and Hygiene – SHO2013 (Guimarães, Portugal, 14-15 February 2013), which was organized by the Portuguese Society for Occupational Safety and Hygiene (SPOSHO). The contributions from 15 different countries focus on: - Occupational safety - Risk assessment - Safety management - Ergonomics - Management systems - Environmental ergonomics - Physical environments - Construction safety - Human factors The papers included in the book are mainly based on research carried out at universities and other research institutions, but they are also based on practical studies developed by Occupational Health & Safety (OHS) practitioners within their companies. As a result, this book will be useful to get acquainted with the state-of-the-art of the research within the aforementioned domains, as well as with some practical tools and approaches that are currently used by OHS professionals worldwide.

Endoscopy in Neuro-otology


Book Description

Endoscopy is firmly established as a major technology for investigation and therapy in a wide range of disciplines. The field of otolaryngology or head and neck surgery owes its existence to the very special difficulties of examining the dark recesses of the head and neck. Therefore, this field has been at the forefront of developing endoscopic techniques for use in this anatomic area. While rhinologists have been quick to embrace the endoscope in the management of sinus disorders, otologists and skull base surgeons have been less than enthusiastic despite the vast range of possible applications in this area. In this book the authors consider the new field of application of endoscope technology in neuro-otology and skull base surgery. Dr. Sanna is part of The Grupppo Otologico, a world-renowned specialist center for the diagnosis and medical and surgical treatment of diseases of the ear, skull base, facial nerve, head and neck, and paranasal sinuses.

Manga High


Book Description

Based on a four-year study, Manga High explores the convergence of literacy, creativity, social development, and personal identity in one of New York City’s largest high schools. Since 2004, students at Martin Luther King, Jr., High School in Manhattan have been creating manga—Japanese comic books. They write the stories, design the characters, and publish their works in print and on the Internet. These students—African-American and Latino teenagers—are more than interested in the art and medium of manga. They have become completely engrossed in Japanese language, culture, and society. Manga High is highlighted by reproductions and content analysis of students’ original art and writing. An appendix includes guidelines for educators on starting a comic book club.
