Popular Abstract in Swedish I avhandlingen undersöks fysikaliska egenskaper hos heterostrukturer med brutna energigap med hjälp av en flerbands k.p modell och självkonsistenta beräkningar. Heterostrukturer med brutna energigap består av halvledarna InAs, GaSb och AlSb och karaktäriseras av en speciell bandstruktur där ledningsbandet i InAs överlappar med valensbandet i GaSb. På grund av bandöverThis thesis examines the physical properties of broken-gap heterostructures using a multiband k.p model and self-consistent calculations. Broken-gap heterostructures, made from InAs, GaSb, and AlSb, are characterized by a special band alignment with an overlap between the InAs conduction band and the GaSb valence band. The band overlap results in anticrossing regions in the energy dispersions and

Artikeln behandlar konsekvenserna av utomäktenskapliga sexuella relationer beroende på kvinnans ståndstillhörighet. Bokens syfte är att förmedla historisk kunskap genom att återberätta individuella livsöden. Det levda livet blottlägger strukturer som omgett människor i olika tider – det kan handla om sociala, kulturella eller ekonomiska strukturer.

The chapter contains an analysis of two similar attempts to institutionalise ‘national memory’ in the Czech Republic and Slovakia after the fall of Communism and dissolution of Czechoslovakia. The study focuses on two documents that create a legal basis for such institutionalisation and on the main actors who initiated the decisions to create these institutes. It is argued that although the origin

Cirkulationsplatser blir en allt vanligare korsningstyp. Personer med synskada upplever svårigheter med att korsa gatan vid cirkulationsplatser. Dagens forskning om vad som skiljer cirkulationsplatser från andra korsningstyper är bristfällig. Denna studie syftar till att ge en bild av vad som är svårt och vad som underlättar när en person med synskada ska korsa en gata i allmänhet och vid cirkulat

In this chapter we emphasize the importance of recognizing the interdependence among exchange rates, interest rates and inflation rates in measuring corporate exposure. First, several issues relating to management’s views of the macroeconomic environment, as well as the firm’s objective and structure will be discussed. These issues must be addressed before multiple regression analysis can be imple

The great transformation of Swedish agriculture in the 18th and 19th centuries was part of a European-wide development sharing similar characteristics. While researchers agree that extensive agro-technological, social and institutional change took place, opinions differ with regards to the causes, spread, timing and sequence of events. Through a systematic study of agricultural production, land us

The APARCH model is a generalization of the GARCH model that attempts to capture asymmetric responses of returns and of volatility to positive and negative `news shocks' -the phenomenon known as the leverage effect. Despite its potential, the model's mathematical properties have not yet been fully investigated. While the capacity of the model to account for the leverage effect is clear from its de

Swedish refugee politics before and during the Second World War and rescue operations 1939-45 with special emphasis on assistance to the Greeks, Raoul Wallenberg´s mission in Budapest and Folke Bernadotte and the White Buses. In the latter cases, I analyse the debates from 1945 to 2012.

The effects on dough rheology at large deformations in elongational flow and shear flow have been studied. The results are related to bread making quality in terms of bread volume and to the physical structure of the dough. A new method for evaluation of an instrumented mixograph is reported. A PLS model, including the five most important parameters from the mixogram, explained 90.9% of the variat

I det västerländska samhället kämpar vi för långa liv men mot åldrandet. Det är bara en av de motsägelser som ålder och åldrande ger upphov till. I Åldrandets betydelser undersöks olika förhållningssätt till och konsekvenser av åldrande. Boken belyser hur kronologisk ålder inte alltid är densamma som den upplevda och hur samhället möter olika åldrar. Exempel tas från såväl hälso- och sjukvården so

A 10-bit, 100-MHz CMOS linear interpolation digital-to-analog converter (DAC) is presented. It includes a 16-tap voltage controlled delay line and a 10-bit binary-weighted DAC with a time-interleaved structure. The linear interpolation not only increases the attenuation of the DAC's image components, but also reduces the glitch of the binary-weighted DAC. The requirement for the analog reconstruct
