This paper discusses the restrictions that dissipation forces on the material parameters and responses of bi-anisotropic media. The treatment is a general time domain analysis where six-vector formalism is applied. Energy conditions set limitations on the optical response dyadics and dyadic susceptibility kernels of the material that have to be satisfied regardless the time dependence of the field
Twenty years have passed since the Brundtland report launched the goal of “sustainable development” (SD). During these decades SD has become widely accepted and it is today established as a fundamental goal in most policy contexts at the international level as well in many countries, regions and cities. A growing research community focussing on various aspects of sustainable development has develo
Popular Abstract in Swedish I Sverige är tillverkningsindustrin en mycket betydelsefull sektor ur flera aspekter. Dagens ökade krav på tillverkade produkter avseende främst kvalité och prestanda medför samtidigt ökade krav på tillverkningsprocesserna. Syftet med denna avhandling har varit att studera hur en specifik plastisk formningsprocess för avancerade tunnplåtskomponenter kan analyseras, optiThe manufacturing industry represents a highly important sector of the Swedish economy. The increasing demands placed on the quality and performance of products that are manufactured places increasing demands on the manufacturing processes involved. The aim of the dissertation has been to study how a particular forming process used in the production of thin sheet-metal parts of advanced character
This work combines economic and demographic data to examine inequality of living standards in Stockholm at the turn of the twentieth century. Using a longitudinal population register with occupational information, we utilize event-history models to show that despite absolute decreases in mortality, relative differences between socioeconomic groups remained virtually constant. The results also show
