When a Virtual Environment (VE) is designed, decisions regarding the navigation of the viewpoint, interaction with objects, and the behavior of the VE itself are made. Each of these can affect the usability and the cognitive load on the user. A VE that had previously been constructed as a prototype tool for the assessment of brain injury has been studied to establish the consequences of such desig

I denna studie klargörs vilka ekonomiska effekter befolkningsförändringar får för svenska kommuner. I studien analyseras data från alla landets 290 kom- muner. Studiens övergripande slutsats är att befolkningsförändringar har bety- dande ekonomiska effekter för landets kommuner, sett till nivån per invånare för kostnader, intäkter, resultat samt anläggningstillgångar och skulder. Resultaten v

We analyze the effects of the increase in China’s import competition on Mexican domestic and international migration. We exploit the variation in exposure to competition from China, following its accession to the WTO in 2001, across Mexican municipalities and estimate the effect of international competition on the individual decision to migrate. Controlling for individual and municipality features

Popular Abstract in Swedish Catecholaminerna dopamin, noradrenalin och adrenalin är en grupp transmittorsubstanser som är involverade i olika funktioner i det centrala nervsystemet. De olika catecholaminerna bildas med hjälp av specifika enzymer. Tyrosin hydroxylas (TH) omvandlar L-DOPA till dopamin (DA), som i sin tur omvandlas av enzymet dopamin ß-hydroxylas (DBH) till noradrenalin, som till sisCatecholamines, comprising the neurotransmitters dopamine (DA), noradrenaline (NA) and adrenaline (A) are synthesized by specific enzymes (tyrosine hydroxylase (TH), dopamine ß-hydroxylase (DBH), phenylethanolamine-N-methyltransferase (PNMT)) in the central nervous system. The development and distribution of different catecholaminergic systems have been described in both the brain and retina of th

Summary form only given. In this paper, we examine the effect of block size on the performance of trellis based quantization. In particular, the Viterbi and tailbiting BCJR algorithms are compared. It is shown that for short blocks of data, the T-BCJR algorithm achieves a superior performance over the Viterbi algorithm (VA). One approach is to use the maximum a posteriori probability (MAP) heurist

In HiperAccess, the scheduling problem takes two forms; firstly, the base station reserves capacity on the uplink for the different terminals, and secondly, the terminals schedule their respective traffic in its assigned share of the channel capacity. Further, the base station generally has less and older information than the terminals, hence, the base station and the terminals may act differently

Achieving upcoming emissions legislation (Euro VI) for heavy trucks is a serious challenge for the manufacturers. Apart from the increasingly strict limits on nitrogen oxides (NOx) and particulate emissions (PM), the limited amount of fossil fuels as well as alarming climate changes simultaneously drives the demand for low CO2 emissions. A likely solution to meet upcoming NOx limits is to use a co

This poster presents the design of a research project in its initial stages. The project Green Search investigates shaping of environmental information, including information on problems and proposed solutions, through their representation in search engine results, in social media tools, and in mobile applications dedicated to environmentally friendly living and consumption and how this is experie
