Segmentation is an important task in all kinds of image analysis. In medical image analysis segmentation has a great clinical value since the aim could be to localize organs or pathologies in order to raise the quality of diagnoses. This thesis consists of three papers where different segmentation techniques have been applied to different imaging modalities. In the first paper a full computer assi
Background: Studies have shown that lifestyle interventions are effective in preventing or delaying the onset of type 2 diabetes in high-risk patients. However, research on the effectiveness of lifestyle interventions in high-risk immigrant populations with different cultural and socioeconomic backgrounds is scarce. The aim was to design a culturally adapted lifestyle intervention for an immigrant
Patients waiting for heart transplantation due to a failing heart can get a left ventricular assist device (LVAD) implanted through open chest surgery. The device consists of a pump that pumps blood from the left ventricle into the aorta. To get the correct rotation speed of the pump, the physicians consider a number of measurements as well as a sequence of echocardiographic images. The important
This paper describes a method of finding thin, elongated structures in images and volumes. We use shortest paths to minimize very general functionals of higher-order curve properties, such as curvature and torsion. Our globally optimal method uses line graphs and its runtime is polynomial in the size of the discretization, often in the order of seconds on a single computer. To our knowledge, we ar
Abstract in UndeterminedAccessibility to adequate health services is a basic human right. Israeli road blocks and checkpoints inhibit access to health care for the Palestinian population. While other studies have dealt with the impact of the barriers, few are based on actual measurements of transport times between locations. Geographical information systems (GIS) and network analysis were used to

A detailed sedimentological study was made on six section walls in the Tvärkroken gravel pit, Idre, west-central Sweden. Based on sediment characteristics, three sedimentary units, units 1-3, were identified. The lowest unit, unit 1, was formed by deposition from sediment-loaded underflows into a stagnant basin. A gradual decrease in water depth is indicated in the upper part of this unit. Post-de
This thesis investigates both the direct effect and indirect effect of corruption on growth via three different investment transmission channels. According to growth theory, different types of investment are commonly considered as important contributors to economic growth. Therefore, this study aims to examine the indirect effect of corruption on growth via following investment transmission channe
Why do we in the Western part of world today tend to believe in technology’s mythical promises rather than in folklore myths? Imaginaries of the future influence political subjects’ actions in the present and play a key role in composing the trajectory towards the future. I have critically applied this notion to the implementation of negative emission technologies in the climate-neutrality strateg
Den allvarliga brottsligheten som begås av kriminella nätverk har ökat drastiskt under de senaste åren. Skjutningar och sprängningar har blivit alltmer förekommande och diskuteras frekvent i medier och politiska debatter. Hur man ska komma till rätta med problemet är en angelägen fråga. Ett av förslagen, för att ge de brottsutredande myndigheterna effektivare verktyg för att förhindra denna typ avSerious crimes committed by criminal networks have increased over the last couple of years. Shootings and explosions have become more common and are frequently discussed in media and political debates. How to solve this problem is an important question and a proposal that has been suggested, with the purpose to give criminal investigation authorities more effective tools to prevent these serious c
The current financial crisis the US and the world finds itself embroiled in has all of the markings of a once-in-a-generation type of economic contraction. In times like these, it is natural to search for comparable frames of reference; Japan’s own banking crisis during the “lost decade” of the 1990’s provides significant parallels to the current state of affairs. Given the severity and relative r
Allvarlig brottslighet som begås inom kriminella nätverk har ökat drastiskt under senare år. Skjutningar och sprängningar har blivit alltmer förekommande och nu diskuteras även finansierandet av skjutvåldet genom narkotika-, smugglings- och ekonomisk brottslighet i politiska debatter. Hur man ska komma till rätta med problemet, med hänsyn till förbättrade tekniska förutsättningar och tystnadskultuSerious crimes committed within criminal networks have increased drastically in recent years. Shootings and explosions are unusually often occurring in Sweden and now the financing of this deadly violence by drug, smuggling and financial crimes is also discussed in political debates. How to effectively deal with the problem, despite improved technology and a culture of silence in criminal gangs, i
This research focuses on the contemporary case study of the Thawra Chronicles, founded by three London-based members of the Lebanese diaspora in the wake of the Lebanese Revolution in early October 2019 to support the social movement from afar, targeting non-Lebanese individuals as well as Lebanese within and beyond its borders. Thawra Chronicles is a multifaceted, independent alternative online o
Självskadebeteende är ett alltmer vanligt förekommande fenomen bland unga och vård är i många fall essentiellt för att lindra problemet. Självskadebeteende kan uttrycka sig på olika vis, bland annat genom att den unge medvetet utsätter sig för riskfyllda sexuella situationer. Syftet med uppsatsen är att med rättsdogmatisk metod undersöka när självdestruktivt sex utgör en grund för vård enligt Self-harm is a growing problem in our society, especially among adolescents. The purpose of this essay is to investigate under which circumstances selfdestructive sex can be considered a reason for compulsory care according to 3 § Care of Young Persons Act, LVU. The current legal conditions will be explored as well as case law. Compulsory care is intended to provide help to young people whose
Version 3 av ecoinvent är den första databasen att erbjuda möjligheten att koppla samman livscykelinventeringar (LCI) utefter olika länkningsalgoritmer. Genom dessa länkningsalgoritmer tar ecoinvent nu fram bakgrundslivscykelinventeringar med både medeldata och långsiktig marginaldata (t.ex. över elmarknader i olika länder). Idealt sett representerar långsiktig marginaldata över elmarknader den ytVersion 3 of the ecoinvent database is the first background database to offer the possibility to link life cycle inventories (LCI) according to different linking algorithms. Using those algorithms, ecoinvent now provides both average and long-term, marginal background LCI data, (e.g. for electricity markets for different countries). Long-term, marginal data for electricity markets ideally represen
Sedan införandet av det kommunala planmonopolet 1947 till följd av den bostadssociala utredningen har planlagstiftningen reformerats flertalet gånger. I förevarande examensarbete studeras den historiska utvecklingen av både det kommunala planmonopolet och dess tillhörande planlagstiftning. Examensarbetet syftar till att studera hur det kommunala planmonopolet kommit att utvecklas och om reformerSince the introduction of the municipal planning monopoly in 1947 following the Housing Social Investigation, the planning legislation has been reformed several times. In this thesis, the historical development of both the municipal planning monopoly and its associated planning legislation is studied. The aim of the thesis is to examine how the municipal planning monopoly has evolved and whether
Over the last couple of years both cameras, audio and radio sensors have become cheaper and more common in our everyday lives. Such sensors can be used to create maps of where the sensors are positioned and the appearance of the surroundings. For sound and radio, the process of estimating the sender and receiver positions from time of arrival (TOA) or time-difference of arrival (TDOA) measurements
Real-time fault monitoring and control of the Vacuum Assisted Resin Transfer Moulding production process requires knowledge of the position of the epoxy flow-front inside the mould. Therefore, a fast and accurate flow-front tracking system is highly prized. Physics-informed grey-box models deliver a good trade-off between high fidelity and data-driven black-box models for designing such a flow-fro
