We have in earlier papers presented an extension of Mueller's dipole cascade model, which includes subleading effects from energy conservation and running coupling as well as color-suppressed saturation effects from pomeron loops via a "dipole swing". The model was applied to the description of the total and diffractive cross sections in pp and gamma * p collisions, and also the elastic cross sect

Background: There is currently a steady increase in the use of wood-based fuels for heat and power production in Sweden. A major proportion of these fuels could serve as feedstock for ethanol production. In this study various options for the utilization of the solid residue formed during ethanol production from spruce, such as the production of pellets, electricity and heat for district heating, w

The electrical output of low concentration systems with standard pv cells is heavily impaired by non uniform irradiation distribution on the cells. In order to design new concentrators that improve the system efficiency by homogenizing the light, a new method of evaluation has been developed. It is based on simulations, and generates an estimated annual output. The method consists of three steps,

This paper attempts to assemble a conceptual framework for understanding to what extent an energy technology is simply a way of putting nature to work, and to what extent it is a way of putting other segments of global society to work. The turn to fossil energy reversed the relation between energy and space, as fossil fuels henceforth propelled new transport technologies that provided access to in

Grossman and Zhou [1993. Optimal investment strategies for controlling drawdowns. Math. Finance 3, 241-276] proposed a strategy to maximize the asymptotic long-run growth rate of one's fortune F, subject to its never falling below lambda sup(0 <= t'<= t) F(t')e(r(t-t')), where 0 <=lambda <= 1 is a fixed constant chosen by the investor and r is a fixed, known, non-negative, continuously compounded

This article compares the articulation of dental stops by two subjects, one Swedish and one British English. The articulations are studied on X-ray motion films and the spectral consequences are studied on spectrograms. Speakers of Swedish are very conscious of a difference in pronunciation of dental stops and hear it as a typical part of an English accent in Swedish. The traditional Swedish expla

Many computing systems are constrained by power budgets. While they could temporarily draw more power, doing so creates unsustainable temperatures and unwanted electricity consumption. Developing systems that operate within power budgets is a constrained optimization problem: configuring the components within the system to maximize performance while maintaining sustainable power consumption. This

I det här avsnittet berättar Emilie om hur det är att studera på universitetet när man inte ser och tar sig fram med rullstol. Emelie berättar också om sin väg till universitetsstudier, farhågor och förväntningar. Hon tar också upp utmaningar på vägen och vilket stöd och anpassningar som har behövts för att göra studierna tillgängliga. I avsnittet pratar vi också om små saker som har stor betydels

This paper examines policy processes surrounding the rise and fall of the proposed EU-wide policy instrument designed to help achieve EU´s renewable energy targets – the trading of Guarantees of Origin (GO). It discusses its origins and examines factors in the policy processes over time leading first to its development and then to its rejection. A first analysis looks at the near-term policy-makin
