An Introduction To G Convergence

An Introduction to Γ-Convergence

Convergent Journalism an Introduction

Learn how to deliver news in any and all media. This one volume teaches you how to master all of the skills needed to be a converged journalist. Don't think only broadcast or print. Think online, air waves, magazines, PDAs, cell phones and electronic paper. Convergent Journalism an Introduction explains what makes a news story effective today and how to recognize the best medium for a particular story. That medium may be the web, broadcast, radio, or a newspaper or magazine - or, more likely, all of the above. This text will explain how a single story can fulfil its potential through any media channel. Convergent Journalism an Introduction shows you, the news writer, editor, reporter, and producer how to tailor a story to meet the needs of various media, so your local news story can be written in a form appropriate for the web, print, PDA screen and broadcast.

Nonlinear Homogenization and its Applications to Composites, Polycrystals and Smart Materials

Although several books and conference proceedings have already appeared dealing with either the mathematical aspects or applications of homogenization theory, there seems to be no comprehensive volume dealing with both aspects. The present volume is meant to fill this gap, at least partially, and deals with recent developments in nonlinear homogenization emphasizing applications of current interest. It contains thirteen key lectures presented at the NATO Advanced Workshop on Nonlinear Homogenization and Its Applications to Composites, Polycrystals and Smart Materials. The list of thirty one contributed papers is also appended. The key lectures cover both fundamental, mathematical aspects of homogenization, including nonconvex and stochastic problems, as well as several applications in micromechanics, thin films, smart materials, and structural and topology optimization. One lecture deals with a topic important for nanomaterials: the passage from discrete to continuum problems by using nonlinear homogenization methods. Some papers reveal the role of parameterized or Young measures in description of microstructures and in optimal design. Other papers deal with recently developed methods – both analytical and computational – for estimating the effective behavior and field fluctuations in composites and polycrystals with nonlinear constitutive behavior. All in all, the volume offers a cross-section of current activity in nonlinear homogenization including a broad range of physical and engineering applications. The careful reader will be able to identify challenging open problems in this still evolving field. For instance, there is the need to improve bounding techniques for nonconvex problems, as well as for solving geometrically nonlinear optimum shape-design problems, using relaxation and homogenization methods.
