Popular Abstract in Swedish Vår värld drivs av förbränning. Från den lilla elden som används vid matlagning till gigantiska gasturbiner och kolkraftverk som genererar en stor del av all elektricitet. Dessutom så drivs nästan alla fordon av förbränningsmotorer. Det har uppskattats att över nittio procent av alla energi vi i världen omvandlar kommer från förbränning i någon form. Det är således ganHigh repetition rate laser diagnostics has proven to be a useful tool for studying combustion phenomena. Laser techniques are, in general, relatively non-intrusive and have the potential to measure specific species at very low concentrations and with extremely high temporal resolution. However, most laser systems in this field of research are limited to repetition rates below 100 Hz, and are thus

Ever since the first three-dimensional computer graphics appeared half a century ago, the goal has been to model and simulate how light interacts with materials and objects to form an image. The ultimate goal is photorealistic rendering, where the created images reach a level of accuracy that makes them indistinguishable from photographs of the real world. There are many applications ñ visualizati

Recently, we proposed using Capon's minimum variance principle to find the fundamental frequency of a periodic waveform. The resulting estimator is formed such that it maximizes the output power of a bank of filters. We present an alternative optimal single filter design and then proceed to quantify the similarities and differences between the estimators using asymptotic analysis and Monte Carlo s

A wide spread of existing and emerging battery driven wireless devices do not necessarily demand high data rates. Rather, ultra low power, portability and low cost are the most desired characteristics. Examples of such applications are wireless sensor networks (WSN), body area networks (BAN), and a variety of medical implants and health-care aids. Being small, cheap and low power for the individua

This essay investigates one of the Naqshbandi-Haqqani Sufi order's centres in London. Sociological theories on New Social Movements are introduced as a means of understanding the activities of the participants at the Sufi centre. Several topics and activities from the centre are presented, among them meditation rituals, physical training and aspects of the relationship between the order's sheikh a

Recension av Semy Kahan: Röster för fred. Nya perspektiv på den israelisk-palestinska konflikten.

This paper contains a simplified framework for the analysis of sequences of images taken by uncalibrated cameras. It is assumed that the correspondences between the points in the different images are known. Corresponding points in a sequence of n images are related to each other by a fixed n-linear form. This form is an object invariant property, closely linked to the motion of the camera relative

Popular Abstract in Swedish Läkemedelsanvändning är en av sjukvårdens viktigaste behandlingsmetoder för att bota och lindra sjukdom. Samtidigt kan läkemedelsanvändning innebära risker. Det finns en risk för att patienterna får biverkningar av sina läkemedel, att läkemedlen fungerar mindre bra tillsammans och att effekten därmed upphör eller förstärks. Vidare finns det risk för att läkemedlen inte Background: There are differences in drug use depending on non-medical factors such as age, gender and socioeconomic status. The combined effect of these factors, with adjustment for multimorbidity, is highly relevant to study to ensure equality in drug use. Objectives: 1. To examine drug use related to age, gender, income and education after adjustment for multimorbidity, in an entire adult popul

I present the status of the THEPEG project for creating a common platform for implementing C++ event generators. I also describe briefly the status of the new versions of PYTHIA, HERWIG and ARIADNE which are implemented using this framework.

The IWA Anaerobic Digestion Model No. 1 (ADM1) was presented in 2002 and is expected to represent the state-of-the-art model within this field in the future. Due to its complexity the implementation of the model is not a simple task and several computational aspects need to be considered, in particular if the ADM1 is to be included in dynamic simulations of plant-wide or even integrated systems. I

Several poly (dimethylsiloxanes) (PDMS) copolymers of dimethylsiloxane (DMS) with ethylene or propylene oxide were tested as artificial carriers for the delivery of oxygen to biological systems. Copolymers with a DMS content of 33% or lower enhanced glucose oxidation by 200% in contrast to the 25% increase produced by the same concentration of perfluorodecalin. When 0.05% of the copolymer with 18%

This thesis presents results from two areas of research. Firstly, the resonant coherent laser techniques polarization spectroscopy (PS), degenerate four-wave mixing (DFWM) and stimulated emission (SE) have been developed in the general field of combustion diagnostics. Secondly, laser induced fluorescence (LIF) has been developed and applied for the visualization of mixture fractions in turbulent n
