Popular Abstract in Swedish Autoimmuna sjukdomar är tillstånd där vårt immunförsvar angriper den egna kroppen. Det finns ett flertal sådana sjukdomar av vilka jag huvud-sakligen har intresserat mig för rheumatoid artrit (RA) och multipel skleros (MS). De behandlingar som finns för de drabbade är idag främst riktade mot ergonomi, smärtlindring och olika former av immunsupres-sion (tex TNFa antikropThe causes of autoimmune diseases are largely unknown today, but there is evidence supporting a substantial complex genetic influence on many of these diseases as well as environmental factors and chance. In this thesis I have tried to get one step closer to the genetic causes of two autoimmune diseases through their induced counterparts in mice, namely rheumatoid arthritis (RA) and multiple scler

Denna avhandling handlar om teoretisk partikelfysik. Partikelfysik handlar om elementarpartiklar och hur dessa växelverkar med varandra, dvs vilka krafter som verkar mellan dem. Detta är hur materien ser ut på den minsta skala vi har kunnat studera experimentellt. Den teori som beskriver de starka, svaga och elektromagnetiska krafterna och de materiepartiklar som vi känner till, kvarkar och leptonThis thesis includes two topics.The first three papers is the major part of this thesis, which is about higher order calculations in the effective field theories of three QCD-like theories. These three QCD-like theories are distinguished by having quarks in a complex, real or pseudo-real representation of gauge group. We wrote their effective field theories in a very similar way so that the calcul

We have examined concurrent and prospective validity of an index of self-reported walking (RW) of 307 home-dwelling women aged 75 years and above, of whom 155 in 1 year had in all 308 falls of which 13% resulting in fractures. It consists of five items concerning various aspects of self-reported walking identified by factor analysis. The sum score on this ''RW-index'' correlated moderately ( r = 0

Theever-increasing test data volume for core-based system-on-chip(SOC) integrated circuits is resulting in high test times andexcessive tester memory requirements. To reduce both test time andtest data volume, we propose a technique for test-architectureoptimization and test scheduling that is based on core-levelexpansion of compressed test patterns. For each wrapped embeddedcore and its decompres

A numerical study has been carried out for slot jet impinging on flat and concave surfaces. Five turbulence models are employed for the predictions of these strongly strained turbulent flows, namely linear eddy viscosity model (LEVM), low-Re explicit algebraic Reynolds stress model (EASM) and three different V2F models. A bounded formulation for Cμ was also introduced to account for the better pre

A recent study of ours suggested that the very presence of a Teachable Agent (TA) from a mathematics learning game might affect students’ test performance when the TA reappeared in the margin of a regular, digital math test. We hypothesized that this effect, which seemed to particularly target low-achievers, was due to the students’ mindset changing from that of “taking a test” to that of “teachin

Decisions regarding strategic software process improvement (SPI) are generally based on the management's viewpoint of the situation, and in some cases also the viewpoints of some kind of an SPI group. This may result in strategies, which are not accepted throughout the organisation, as the views of how the process is functioning are different throughout the company. This paper describes a method f

Controlling an induction machine has been a difficult task since its invention, especially at low speed operation and during highly dynamic regimes, where the required torque/speed changes constantly. This paper aims to present the validation and implementation of a deadbeat direct torque and flux control scheme (DB-DTFC) for induction machines on a multilevel platform consisting on an FPGA, a rea

This report was initiated and conducted as input to the discussions based on the “Vision 2015” document for the Nordic Swan that explicitly states a wish to find ways to make use of ecolabelling in the green public procurement (GPP) setting. In 2014, the Directive (2004/18/EG) on public procurement was revised and replaced by Directive (2014/24/EU). Some of the restrictions in using ecolabelling i
