The Preservation of Favoured Morphs in the Struggle Between Sexes

Sexual selection is particularly likely to promote population divergence, because sexual traits are expected to be subject to rapid evolutionary change. Identifying the relative roles of particular barriers to the amount of total reproductive isolation between populations or closely related species can provide important clues to the mechanisms of population divergence and speciation Phenotypic tra

Industrial Induction Heating - with a focus on multi coil solutions

Most types of materials and components use heating during the manufacturing process, with a large potential for cost and energy savings. Induction heating is the most energy efficient industrial heating technology for many applications, but so far technical limitations has delayed large scale introduction. The difficulties relate to heating of large flat and curved surfaces, and, perhaps most impo

Krishantering, hushåll och stormen Gudrun : Att analysera hushålls krishanteringsförmåga och sårbarheter

Popular AbstractStörre kriser och katastrofer som stormen Gudrun och dess konsekvenser är sannolikt att vänta i framtiden. Det råder dock ovisshet om vilka kriserna kommer att vara och under vilka förutsättningar. Nya och kompletterande vetenskapliga studier och metoder inom kris- och katastrofforskningen måste till för att öka samhällets kunskap om och förmåga att hantera kända och okända hotbildSevere crises and disasters such as the Hurricane Gudrun and their consequences will probably occur in the future. However, there are many uncertainties concerning disasters and their effects. New scientific approaches and methods for crisis and disaster research must be developed to increase the knowledge and ability of societies to manage known and unknown threats. Substantial research on the em

Non-radiating sources in time-domain transmission-line theory

The concept of non-radiating sources is introduced to transmission lines in the time-domain analysis. A method is presented to construct localized voltage and current sources which do not produce any fields outside the source domain. These sources cannot therefore be detected by measurements made outside the source region. The importance of such sources for the uniqueness of the inverse source pro

Homogenization of a dielectric mixture with anisotropic spheres in anisotropic background

This paper treats the problem of calculating the macroscopic effective properties of dielectric mixtures where both the inclusions and the background medium can be anisotropic. For this homogenization process, the Maxwell Garnett -type approach is used where the inclusions are assumed to be spherical and embedded in a homogeneous background medium. The anisotropy of the background medium has to be
