Popular Abstract in Swedish Många har frågat mig vad mitt doktorandprojekt egentligen handlar om. Mitt svar brukar variera beroende på hur insatt personen ifråga är. Normal brukar jag börja med ungefär följande förklaring: I våra kroppar finns proteiner som hjälper till att utföra och reglera kemin som krävs för att hålla de biologiska processerna igång. Att förstå denna kemi kan vara till hjälp Accurate calculation of energies for protein reactions is a hard problem. There are many reasons for wanting to calculate these energies, e.g. ligand design and the study of enzyme reactions. There are two major problem involved in these kinds of calculations. First, the large number of local minima in proteins introduces uncertainties when studying single structures. Second, the size of proteins

Many problems in computer vision, such as stereo, segmentation and denoising can be formulated as pseudo-boolean optimization problems. Over the last decade, graphs cuts have become a standard tool for solving such problems. The last couple of years have seen a great advancement in the methods used to minimize pseudoboolean functions of higher order than quadratic. In this paper, we give an overvi

Expanding bio-energy can help to fight climate change and improve energy security. The bio-energy industry in the EU is booming. Much of this success is based on the supportive EU directives and strategies that are stimulating national policies and innovation processes. However, the bio-energy industry is being confronted with a number of interconnected challenges that threaten its reputation, leg

Att avlägsna en luftförorening från en bostad kan ske på olika sätt, dels genom ventilationen dels genom att vissa föroreningar avlägsnas genom någon typ av filtrering av luften. Filtrering av luften används t.ex. vid olika typer av allergiska problem för att avlägsna icke önskvärda partiklar, t.ex. pollen. Filtrering har också föreslagits som en möjlig metod att minska stråldosen i samband med ra

It is not too far fetched to claim that celebrity is a phenomenon that is difficult to define. It is hard to maintain rigid hierarchies between the components that make up celebrity. One of them can be described as glamour. In the paper I examine ways to understand glamour as an intrinsic part of the symbolic construction of celebrity. It has been used as a inherent quality in the person (Gould, 2
