Improving diagnosis of acute coronary syndromes in an emergency setting: A machine learning approach

Acute coronary syndrome (ACS) is the biggest people killer in the western world today. Despite well trained physicians and reliable diagnostic tools, diagnosing ACS early in the emergency departments (ED) remains a challenge. In this thesis we used machine learning, via logistic regression models and artificial neural network ensembles, to investigate the possibility of predicting ACS at an early

Solutions and their ambiguities for structure and motion problems

This thesis revolves around the problem of solving the structure and motion problem in computer vision. This is the problem of reconstructing the world, the structure, from images taken by a number of cameras undergoing an unknown motion. Much of the thesis is centred on the problem of finding initial estimates of the structure and the motion using a small set of image data. These initial estimate

Böcker, bildning, makt : Arbetare, borgare och bildningens roll i klassformeringen i Lund och Helsingborg 1860-1901

This dissertation deals with the question of why and how the issue of workers' education came to be part of both bourgeois and working class formation during the second half of the 19th century and how it contributed to the shaping of new social relations. The theoretical perspective is based on the concept of hegemony indicating that a leading class has to establish and maintain its leadership by

Fouling of Ultrafiltration Membranes due to Adsorption of a fatty acid

A study of fouling of ultrafiltration membranes due to adsorption of a fatty acid in the membrane matrix has been done. Octanoic acid was used as a model substance. It has been shown that a low-molecular-weight hydrophobic solute can have detrimental effects on the flux of hydrophobic ultrafiltration membranes even though the size of the solute is much smaller than the cut-off of the membrane and

Childhood depression: teachers' and children's perceptions of the symptoms and causes of depression in Jordan

The purpose of this thesis is to scrutinise the situation of children with depression in Jordan. The Jordanian translation of the Children’s Depression Inventory (CDI) is used in this study. The original sample on which the study tools were applied consisted of 534 children. The data was analysed according to the SPSS programme. The results of the study show that the Jordanian translation of the C

Emotion and Learning - A Computational Model of the Amygdala

The amygdala is a small subcortical structure that has long been implicated in the conditioning of fear and other emotions. It is heavily interconnected to a number of both cortical and subcortical structures and is thus well placed to integrate sensory inputs from multiple areas to produce emotional reactions directly as well as influence learning and attention systems. Data suggests that the amy

L'Etat, c'est pas moi : Reframing citizenship(s) in the Baltic republics

This book speaks to readers with a particular interest in the Baltic states as well as to those with a broader interest in post-communist democratization and citizenship. The notion of citizenship has not been prominent in academic perspectives on post-communism. This study aims at bringing citizenship back into these perspectives. Starting from the idea that citizenship is both a condition of de

Obstacle Problems for Green Potentials and for Parabolic Quasiminima

The thesis consists of two parts. In the first part pure potential theoretic methods are employed to study the obstacle problem connected with a uniformly elliptic second-order differential operator in divergence form. Regular points of the obstacles are characterized by the classical Wiener criterion. The second part deals with a class of functions satisfying a certain integral inequality. A pr

On Discrete-Event Simulation and Integration in the Manufacturing System Development Process

DES is seldom used in the manufacturing system development process, instead it is usually used to cure problems in existent systems. This has the effect that the simulation study alone is considered being the cost driver for the analysis of the manufacturing system. It is argued that this is not a entirely correct view since the analysis has to be performed anyway, and the cost directly related to

Dependability of IT Systems in Emergency Situations – Theory and Practice

As our dependence on IT systems increases, evaluating the dependability of critical IT systems becomes more important. One of the main challenges in software reliability engineering is the sensitivity of software systems to a changing usage. This is especially important for systems that are critical in the aftermath of a crisis and for which reliability is the most important aspect of dependabilit

ONLINE HATE CRIME – SOCIAL NORMS AND THE LEGAL SYSTEM

A central point of departure for this socio-legal study about online hate crimes concerns the significance of analysing and understanding social norms in relation to these crimes on the Internet. This is of importance not least when one approaches the issue of how law and the legal system may contribute towards positive developments in this field and prevent hate crimes. It is apparent that law an

GIS-hydrological modelling in arid lands : a geographical synthesis of surface waters for the African Red Sea region in the Sudan

The magnitude and availability of surface waters in the arid/semi-arid Sudanese Red Sea region has been examined. In conjunction with the research objective, opinions and methodologies applied by previous researchers have been assessed. The study applied a geographical hydrological synthesis within a GIS framework. As a system with advanced geo-modelling capabilities, GIS is used to integrate spat

I den värld vi drömmer om: utopin i Elin Wägners trettiotalsromaner

The aim of this present thesis is to present the Utopian scheme in Elin Wägner’s novels of the nineteen-thirties: Dialogen fortsätter (1932) (“The Dialogue Continues”), Mannen vid min sida (1933) (“The Man by my Side”), Genomskådad (1937) (“Unmasked”) and Hemlighetsfull (1938) (“Mysterious”). With her authorship Wägner was aiming for a new social order, a radical change, polväxling (a shift of pol
