Computational Aspects of Structural Acoustics and Vibration : CISM Courses and Lectures

Computational methods within structural acoustics, vibration and fluid-structure interaction are powerful tools for investigating acoustic and structural-acoustic problems in many sectors of industry; in the building industry regarding room acoustics, in the car industry and aeronautical industry for optimizing structural components with regard to vibrations characteristics etc. It is on the verge

Lateral Superlattices in Commensurate Magnetic Fields: Electronic Structure, Transport and Optical Properties

The present thesis is devoted to the theoretical study of two-dimensional electron systems moving in a modulated lateral periodic potential and a competing perpendicular magnetic field. The three introductory chapters offer a brief exposition of the basic issues in this area -- the description of the electron motion in a prependicular magnetic field, the group of magnetic translations and the comm

Transport Phenomena in Fires

Controlled fires are beneficial for the generation of heat and power while uncontrolled fires, like fire incidents and wildfires, are detrimental and can cause enormous material damage and human suffering. Transport phenomena such as buoyant flow, momentum, convective heat and mass transfer as well as chemical reactions between combustible species and oxygen from the surrounding air play important

Exotic materials in radome and antenna design

The purpose of this paper is to investigate the potential of complex or exotic materials in radome and antenna design. The existing analysis methods need to be extended to cope with these materials in generic radome and antenna geometries. This paper focuses on electromagnetic properties of the material, the means of realizations, and the methods of computations. The main objectives of this paper

Key Environmental Performance Indicators (KEPIs): A new approach to environmental assessment

A new Key Environmental Performance Indicators (KEPIs) approach has been developed considering the perspective of a designer who may like to improve the environmental performance of the products but has limited resources and understanding of complex environmental issues. This approach empowers the designer with indicators like the area of PWB, the amount of precious metals etc which account for th

Library and Information Science in Context: the development of scientific fields, and their relations to professional contexts

The purpose of this paper is to discuss how theories of social and intellectual development of scientific fields can be used to analyze LIS, and especially its relationship to other research areas and the library and information field of practice. Scientific fields can be seen as reputational work organizations, where degrees of task uncertainty and mutual dependency control the coordination and d

Simulation of heat generation in elasto-plastic materials

The demand for improved models for simulation of mechanical problem is today very great, especially since today's computer capacity makes it possible to simulate large and complicated problems. In some applications, temperature effects and the heat generated from inelastic deformation can not be neglected in order to achieve a good accuracy of the simulation. In this thesis, a model for simulatio
