We compare the performance of different detection schemes in terms of resulting pairwise error probability in Rayleigh-fading channels. We introduce a unified analysis framework used to compare sensitivity to Doppler and noise. The analyzed methods include: pilot symbol assisted modulation, differential detection, multiple-symbol differential detection and detection using superposed pilot symbols.

Abstract in Danish Kapitlet indkredser, beskriver og problematiserer begrebet patientologi. Patientologi betyder videnskab om det at være patient; altså viden der sigter på at gøre os klogere på det at være patient; ikke viden der i første instans sigter på at gøre noget bedre eller anderledes for patienter inden for et fags rammer. Med afsæt i amerikaneren Pamela Brink kan patientologi forstås so

The thesis Med Lenin på byrån (With Lenin on the drawer) studies magazines produced by the Swedish communist movement during the inter-war years and has two aims; firstly to determine if (and how) class-norms were constructed through descriptions of gender and sexuality, and secondly if (and how) norms regarding gender and sexuality were constructed through descriptions of class. One of the underl

Natural products have been shown to be an important source of novel compounds for the development of new drugs and pesticides. However, many biologically active natural products contain reactive functionalities that make them toxic. By modifying such reactive compounds chemically it is possible to make use of the reactivity to form novel "natural product-like" compounds and at the same time reduce

According to medieval canon law, a marriage could be declared invalid if the consent had been given through force or fear. This ruling was a natural consequence of the insistence on free consent as the only requirement for a valid marriage. It did, however, entail a number of both practical and theoretical problems. It could be difficult to prove force and fear within the family, but also to defin

Popular Abstract in Swedish P2 receptorernas roll vid utvecklingen av hjärt-kärlsjukdom I västvärlden orsakar hjärt-kärlsjukdomar mycket lidande och är den vanligaste dödsorsaken i befolkningen. Till gruppen hjärt-kärlsjukdomar kan man räkna hjärtinfarkt, kärlkramp, högt blodtryck, hjärtsvikt och slaganfall. En gemensam komponent i sjukdoms-utvecklingen är en förändring i blodkärlsväggen som gör Extracellular nucleotides induce dilatation and constriction of blood vessels by activation of P2 receptors. In this thesis the vasomotor effects of P2 receptor activation were studied in the rat mesenteric artery, and their changes in congestive heart failure (CHF) were evaluated using in vitro pharmacology, electrophysiology and competitive RT-PCR. Vasodilatation was induced by activation of P2Y

This paper deals with numerical simulations of circular impinging jets with heat transfer, by means of Large Eddy Simulation (LES). The LES code uses higher order finite-differences on staggered Cartesian non-uniform grids. The current LES have the potential of dealing with transition as well as providing data on details of larger scale structures, statistical correlations and turbulent spectral c

Christening gifts are on the one hand very concrete and material. They have a value, both economically and emotionally. But on the other hand they also have a function that is neither concrete nor material. They express feelings, hopes, and dreams of belonging and community. The gift has a meaning for both the one who receives it, and the one who presents the gift.

This paper presents the design and implementation of a coarse-grained reconfigurable architecture, targeting digital signal processing applications. The proposed architecture is constructed from a mesh of resource cells, containing separated processing and memory elements that communicate via a hybrid interconnect network. Parameterizable design of resource cells enables flexible mapping of arbitr

Popular Abstract in Swedish Parkinsons sjukdom är en relativt vanlig kronisk neurologisk sjukdom som karaktäriseras av att nervceller i ett specifikt område djupt i hjärnan av okänd anledning successivt dör. Dessa celler producerar signalsubstansen dopamin, vilken bl a är nödvändig för normal rörelseförmåga. Motoriska symptom (skakningar, muskelstelhet, förlångsammade rörelser och balansstörningarThis explorative study aimed to apply, develop, and evaluate assessment methods at various levels in cell replacement therapy for Parkinson’s disease (PD). Observed motor effects in five grafted patients support that timed motor tasks and clinical ratings of parkinsonism are able to monitor motor function, but their psychometric properties need further attention.
