Popular Abstract in Swedish Denna avhandling syftar till att förbättra styrningen av myoelektriska handproteser. De primära målen har varit (1) att generera korrekt kontroll för så många handrörelser som möjligt, (2) att förbättra träningsförfarandet så att operatören på ett intuitivt sätt snabbt kan bemästra ett flertal rörelser och (3) att minska tiden som behövs för att matematiskt justera in sAn investigation of improvements of myoelectric prostheses has been undertaken. The primary aims of this thesis were (1) to generate an accurate prediction of as many hand movement as possible, (2) to produce a training setup for subjects allowing intuitive and instant control over multiple movements, and (3) to reduce the training cycle for the control system to a maximum of a couple of minutes t

Popular Abstract in Swedish Vår kropp är uppbyggd av flera olika typer av stödjevävnader tex ben, brosk, muskler och hud. Den utgör kroppens stomme och bidrar med både stödjande och elastiska funktioner i kroppen. Brosk är en specialiserad form av bindväv som bekläder alla ledytor i kroppen och dess specifika sammansättning förser leden med en i det närmaste friktionslös rörelseförmåga. Broskets The work in this thesis has been focused on chondrocyte integrins and their interaction with the matrix proteins chondroadherin (CHAD) and collagen type II (CII). Affinity purification of CHAD-binding proteins from chondrocyte lysate, followed by immunoprecipitation of EDTA-eluted material identified alpha2beta1 as a CHAD-binding integrin. Interaction between alpha2beta1 and CHAD was found to prev

Chancroid caused by Haemophilus ducreyi, has been described as a significantly predisposing factor of HIV heterosexual transmission in an endemic region of both diseases. Antibiotic resistances are extensively found in H. ducreyi and many of the resistances are due to the presence of resistance plasmids. A high tendency of drug resistances has commonly been found among isolates derived in Thailan

Popular Abstract in Swedish Intresset för förnybara bränslen har ökat stadigt under de senaste åren. Att byta ut fossila mot förnybara bränslen kan minska utsläppen av växthusgaser till atmosfären och därmed minska klimatpåverkan av dessa men även minska vårt beroende av olja. Biobränslen som t.ex. etanol, biodiesel eller biogas, räknas till förnybara bränslen eftersom de inte bidrar till en ackumReplacing fossil fuels by biofuels such as ethanol is considered a promising alternative to reduce greenhouse gas (GHG) emissions and mitigate climate change. Biofuels produced from lignocellulosic biomass, so-called second generation biofuels, result in decreased GHG emissions and limit competition with food and animal feed production. Interest in producing ethanol from lignocellulosic biomass ha

The cartilage extracellular matrix consists of the collagen network which enmeshes the large aggregating proteoglycan, aggrecan. Accessory molecules regulate the formation and maintenance of these structures. This thesis studies aspects of cartilage assembly during development and its degradation in disease, focusing on the collagen network. In the first paper, a model of cartilage degradation is

Background. The thrombosis risk is increased in active ulcerative colitis. The limited number of reported complications have predominantly been cerebrovascular but other vessel territories may also be affected. Patient. During a severe attack of ulcerative colitis a 37-year-old woman suffered occlusion of all left coronary artery branches. Serial angiographies showed progressive recanalisation of

Visual quality assurance techniques focus on the detection and qualification of abnormal structures in the image of an object. The features of abnormality are extracted through image mining, whereupon classification is performed on characteristic combinations. Many techniques for feature extraction have been proposed, but the feed-forward neural network is seldom utilized despite its popularity in

In August 2015 a Swedish newspaper claimed that the Sweden Democrats were the largest political party in Sweden based on the results of single poll. We ask ourselves if this is a correct conclusion, considering the fact that the three largest parties in the poll were of roughly the same size. We analyse the parameter space and identify the subspace where the Sweden Democrats are the largest party.
