A statistical distribution for the number of CDMA RAKE fingers, N T, to be assigned in order to track a given percent of the total received power has been derived. The obtained distribution reveals a strong dependence of NT on the system bandwidth, the median RMS delay spread, its standard deviation and other environment specific parameters. Also, a statistical distribution for the fading width fw

This talks contains a short introduction to Chiral Perturbation Theory and the existing calculations to two-loop order in the mesonic sector. I include a discussion on which quantities the expansion can be organized in. The present best values of the Low-Energy-Constants as determined from continuum physics are given as well as the assumptions underlying the fits to experimental data. I present pl

Requirements on well documented management systems for Nuclear Power Plants (NPPs) are relatively new and in different developmental phases. Thus there is a need of knowledge about well-functioning Safety Management Systems (SMSs) also considering other goals and restrictions. Since there ia a lack of mature management systems for NPPs it is important to learn from other NPPs, but also from other

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
