Event-based data are encountered daily in many disciplines and are used for various purposes. They are collections of ordered sequences of events where each event has a start time and a duration. Examples of such data include medical records, internet surfing records, transaction records, industrial process or system control records, and activity diary data. This thesis is concerned with the ex...

Cerebrospinal fluid (CSF) biomarkers may be used to identify and monitor pathological processes in the central nervous system. CSF biomarkers in Alzheimer’s disease (AD) include β-amyloid 42 (Aβ42), total-tau (T-tau) and phosphorylated-tau (P-tau), reflecting brain amyloid, axonal and tangle pathology, respectively. This dissertation aims at defining and validating CSF biomarkers for amyloid an...

The aim of this thesis was to study and implement advanced real-time rendering techniques for complex materials such as human skin. The project included investigation on how to adapt and simplify complex skin rendering models to fit current game engines. Also, the task included looking into recent research on spherical harmonics and wavelets. The goal was to determine whether they can be used t...

I denna avhandling studeras prostatacancerns naturalförlopp och värdet av befi ntliga prognostiska faktorer. Man studerar också några nya tänkbara prognostiska faktorer. Dessutom tittar man på tids trender för prostata tumörer som är upptäckta incidentalt vid två olika typer av operationer, som görs vid vattenkastningsbesvär. Avhandlingen bygger på två unika prostata cancer material som samlats...

The ether lipid analogue l-octadecyl-2-methyl-rac-glycero-3-phosphocholine (ET-18-OCH.,) has been shown to be a direct inhibitor of Swiss 3T3 fibroblast and BG1 ovarian adenocarcinoma cell cytosolic phosphoinositide selective phospholipase C (PIPLC) using |3H|-phosphatidylinositol-(4, 5)-bisphosphate (|'II|I"II'<) as the substrate. The inhibition occurred when ET-18-OCH., was incorporated into ...

The domestication is the process where animals have adapted to human conditions. A prerequisite for domestication is tame behaviour towards humans and subsequently, selection for other desirable traits took place which led to changes in several behavioural and physiological parameters. The domestication of chickens (Gallus gallus) was initiated around 8000 years ago, and today we see clear phen...

Visualization Toolkit (VTK) is an open source, cross-­‐platform library for visualization, 3D graphics and image processing, written in C++ and OpenGL. In this report we investigate how VTK can be extended and modified to add support for the iPad. In particular the ...

Triage, derived from the French word for sorting, aims to assess and prioritize injured patients, regardless of whether the injuries are sustained from everyday road traffic accident with few injured or a mass casualty incident. Triage seeks to provide the greatest benefit to the largest number of casualties in order to minimize morbidity and mortality. Triage in a pre-hospital setting entails ...

Counting and classifying blood cells is an important diagnostic tool in medicine. Support Vector Machines are increasingly popular and efficient and could replace artificial neural network systems. Here a method to classify blood cells is proposed using SVM. A set of statistics on images are implemented in C++. The MPEG-7 descriptors Scalable Color Descriptor, Color Structure Descriptor, Color ...

Artikelns syfte är att skapa en ökad förståelse för de utmaningar som uppstår när man i klassrumspraktiker skapar mening åt informationskompetens i allmänhet och i synnerhet åt trovärdighet. En kvalitativ studie har genomförts i två svenska gymnasieklasser med elever från andra året på samhällsvetenskapligt program. Artikeln ger en inblick i de utmaningar som pedagoger möter i samtidens skola n...
