A major problem in the development of intelligent hearing aids is often referred to as the cocktail party problem. It describes the remarkable ability of the human brain of filter out unwanted sounds in a noisy environment, while focusing on a single talker or conversation.

Vatten är en livsnödvändig resurs såväl för människor som för miljön. Globalt är vattenresurser under ökad belastning vilket resulterar i vattenbrist lokalt. Skillnaden mellan ökande vattenbehov och den naturliga gränsen för tillgången av sötvatten utmanar myndigheterna att hitta lösningar som uppfyller samhälleliga och ekonomiska intressen utan att äventyra miljöinverkan. Vattenproduktion, flöde Water is an essential resource for humans as well as the environment and water resources globally are under increasing pressure resulting in local conditions of water scarcity. The tension between increasing water demands and the natural limit to freshwater supply challenges authorities to find solutions that fulfil societal demands and economic purposes without compromising environmental integrit

Datorsimuleringar blir ett allt viktigare verktyg för att förstå, utveckla och effektivisera alla sorters processer och produkter i vårt samhälle. Det är ofta svårt att exakt efterlikna verkligheten, och för att göra simuleringarna möjliga används ofta modeller som förenklar verkligheten.In this master thesis computational fluid dynamic simulations of two plate heat exchanger channels have been performed in Ansys CFX. The full geometry of the channels has not been included, the channels were modeled with a flat geometry instead of a corrugated pattern. To account for the effect of the corrugation on the pressure drop, one-time pressure losses and momentum sources were added in the

The focus in this thesis is on how medical patient records have developed and changed due to the modernization processes in the Swedish health care system during the period 1900– 1986.

Sedan 2005 har uppehållstillstånd beviljats en utlänning om det vid en samlad bedömning av utlänningens situation föreligger sådana synnerligen ömmande omständigheter att han eller hon bör tillåtas stanna i Sverige. I juli 2014 trädde en bestämmelse i kraft som stadgar att barn kan få stanna i Sverige om det föreligger särskilt ömmande omständigheter. Uppsatsens syfte är att utreda rättsläget för Since 2005 an alien can be granted residence permit if, after an overall assessment of the alien’s situation, there are such exceptionally distressing circumstances that he or she should be allowed to stay in Sweden. In July 2014 a provision came in force which stipulates that children may stay in Sweden if there are particularly distressing circumstances. The purpose of this thesis is to determin

Det är en obehaglig realitet att i Sverige döms oskyldiga personer för brott de inte har begått. Statistiskt sett händer det sannolikt mycket sällan men över en tillräcklig lång tidsrymd är det oundvikligt. Detta trots den lagstadgade oskyldighetspresumtionen som ger den som är misstänkt för ett brott rättigheten att betraktas som oskyldig till dess att motsatsen har bevisats. Högsta domstolen hIt is an uncomfortable reality that in Sweden innocent individuals are sentenced for crimes they have not committed. Statistically, it happens most likely very seldom but, given a sufficient length of time, it is unavoidable. The Swedish Supreme Court has in NJA 1980 p. 725 expressed the evidentiary requirements for convictions in criminal cases. The guilt of the accused must be beyond reasonable

Using the WAM wave model to hindcast the waves between Jan 1st 2004 and Dec 31st 2009 the parameters significant wave height, direction of wave propagation and spectral wave peak period were extracted from the time series and assembled in a wave atlas. The model was forced with point source wind

Myndighetschefer anställs av regeringen som en del av den så kallade utnäm-ningsmakten. Anställningen av myndighetschefer är emellertid inte helt dis-kretionär, den centrala regleringen på området, 12 kap. 5 § regeringsformen, stadgar att vid tillsättningen av dylika tjänster ska avseende endast fästas vid sakliga grunder. Uppsatsen utreder bakgrunden, intentionen och innebörden av denna regel. ViTop level-management in the Swedish civil service is appointed directly by the government.
