Localization is an important enabling technology for many applications, such as wireless sensor networks, emergency rescue services, civil defense and transportation. Suppose that a room is equipped with several microphones (or sensors), and one person is making a sound while moving around in the room. Can one find microphone and sound source positions as well as reconstruct a room geometry? The a
I denna rapport studeras i vilken grad framtida energi- och transportsystem med låga utsläpp av växthusga¬ser är förenliga med övriga svenska miljömål. Utgångspunkt tas i de scenarier som tagits fram i forsk¬ningsprogrammet LETS. Ibland uppkommer synergier som innebär att minskningar av utsläppen av växt¬husgaser samtidigt leder till att det blir lättare att uppnå andra miljömål. I andra fall uppkIn this report potential synergies and conflicts between greenhouse gas mitigation and other environmental objectives (EOs) are studied. A starting point is taken in energy scenarios developed within the research programme LETS (www.lets2050.se). Environmental impacts appear in all steps of the energy chain, from land-use effects (both direct and indirect) of renewable energy extraction to emissio
Background: Several countries have increased patients' abilities to choose their health care providers, frequently under the assumption that patients are themselves the best agents to make such decisions. In parallel, national and regional health authorities have enhanced access to Internet based information sources (IBIS) to assist patients in making an informed choice. Relatively little, however
Abstract in UndeterminedAccurate estimation of forest net primary productivity (NPP), biomass, and their sensitivity to changes in temperature and precipitation is important for understanding the fluxes and pools of terrestrial carbon resulting from anthropogenically driven climate change. The objectives of this study were to (1) estimate potential forest NPP and biomass for New England using a re
Populärvetenskaplig sammanfattning: Rassepautasjtjåkka är ett litet bergsmassiv beläget i norra Lappland. I massivet återfinns fyra stora nischer strax under glaciationsgränsen. Dessa nischer har en gång blivit uteroderade av glaciärer, men idag återfinns endast perenna snölegor i området. Skillnaden mellan en glaciär och en perenn snölega är att en glaciär har intern rörelse. En tjocklek på cirkaSince the mid 1970s the general retreating trend for glacier in Scandinavian have ceased and some glaciers have even started to advance. This is due to a more maritime influence on the climate, which means increased precipitation in winter and lower summer temperature. A more maritime climate can be said to be favourable for glacier growth. Under such climate conditions is it possible that new gla
Prostitution as a construction - The social worker in the tension between society and the individual Discussions about prostitution seems to be of large interest for different feminist groups. The main discussions are about whether people sell sex as a result of free will, or if prostitution is a part of patriarchal structures, and that people selling sex, have been forced to do so in one way, or
Förändras mikroorganismers ”samhällsstrukturer” över säsongen? Överallt i marken finns det mikroorganismer som servar växterna med näring, både i form av att de hjälper till att ta upp näring och dela med sig av, och genom att de bryter ner dött material och därmed gör näring tillgänglig. Jag har ställt mig frågan om mikroorganismer i jorden varierar i mängd, sammansättning och aktivitet över säAbstract Seasonal variation in microbial community composition was investigated from early spring tillautumn alonga sandy grasslandslope with variation in soil moisture, vegetation composition and nutrient availability.The testedhypotheses were:(1) the microbial community composition will change with theseason,(2) microbial biomassis highestin spring,(3) saprotrophic fungi will be more abundantin

Varje medlemsstat har förbehållit sig rätten att lagstifta inom rättsområdet direkt beskattning. Det medför att medlemsstaterna är skatterättsligt suveräna och att gemensamma EU-beslut kan fattas inom detta rättsområde, under särskilda omständigheter. Trots detta har EU-domstolen sedan ca 30 år tillbaka, avkunnat domar som berör frågor huruvida regler inom den direkta beskattningens område är föreOver the years it has become clear that the Court of Justice of the European Union may, despite the principle of fiscal sovereignty rule on the compatibility of domestic tax measures belonging to the field of direct taxation, with the fundamental freedoms. Truthfully, the compatibility assessment is found much earlier in other fields of law. The last step of the methodology used by the Court encom

På senare tid har det påträffats olika typer av skador på fibercementskivor monterade i fasader som har varit svåra att härleda till en specifik orsak. Den främsta skadan som uppkommit är sprickbildning men det har även påträffats andra defekter så som utbuktande skivor. Dessa skador har i flera fall härletts till handhavandefel vid montage men fukt-och temperaturbetingade rörelser tros även vara Recently, various types of damages have been found on fibre cement boards mounted in facades which have been difficult to trace to a specific cause. The main damage that has occurred is cracking but other defects have also been found, such as bulging boards. These damages have in several cases been attributed to handling errors during assembly, but moisture and temperature-related movements are al
Background: Type 2 diabetes (T2D) and dementia represent a growing dual burden in aging populations. These conditions share pathophysiological mechanisms that may create a self-reinforcing cycle in which cognitive impairment affects diabetes management, a crucial factor for preventing complications. Despite Sweden's comprehensive care, there is limited longitudinal evidence on how cognitive
Sverige genomgår för tillfället strukturella förändringar i befolkningssammansättningen. Andelen äldre blir större och andelen yngre blir tvärtemot mindre. Denna demografiska utveckling får stora följder för samhället, inte minst för bostadsmarknaden. Människor i olika åldrar har olika boendepreferenser och när fördelningen i samhället förändras, förändras också behovet av olika typer av bostäder.

The increasing urbanization trends in Sub-Saharan Africa (SSA) and the proliferation of urban poverty together with the explosion of informal urban settlements have lead to a shift in the international poverty alleviation agenda from the focus on rural poverty to an increased emphasis put on the particularities of urban poverty. Kenya is one of the fastest urbanizing countries in SSA and the major
Insect herbivory can have important consequences for the functioning of terrestrial ecosystems. Despite a growing recognition of the role of herbivores in above-ground–below-ground interactions, our current understanding is mainly restricted to studies of vertebrates in grassland and tundra ecosystems, while ecosystems with tree-like canopies (termed forests below) and invertebrates remain underst
Populärvetenskaplig sammanfattning Bakterieflora och Antibiotisk Resistens i Gouldsamadinen Gouldsamadinen (Erythrura gouldiae) är en färggrann fink som lever i norra Australien. Arten har minskat i antal under de senaste decennierna och idag anses den vara utrotningshotad. I ett försök att stärka den vilda populationen har man genomfört återintroduktioner med individer från voljärer till artensAbstract The release of captive bred birds may be an important conservation tool for endangered species of birds. In Australia attempts have been made to re-introduce Gouldian finches in the wild and the same action is considered for other endangered Australian finches. This might pose a risk as a broad range of infectious diseases have been described in captive Australian finches yet little is k
