This master's thesis investigates both custom lossless compression and high-quality lossy compression of microscopy images of white blood cells produced by CellaVision's blood analysis systems. A number of different compression strategies have been developed and evaluated, all of which are taking advantage of the specific color filter array used in the sensor in the cameras in the analysis
Spårvägen is a neighborhood in Malmö that is being transformed from a bus depot in an old industrial area to an attractive residential neighborhood. The thesis investigates the role of greenery and biodiversity in the changing urban landscape in Spårvägen. The research analyzes how tensions between political demands on biodiversity in relation to economic structures are forming the urban greenery
Abstract The idea of the spread of life through the galaxy is, in most minds, considered science fiction. Yet, scientists argue that most galaxies have had more than enough time for civilisation development and space travel. In this thesis I simulate how civilisations can spread through the galaxy via close encountering stars, assuming they travel at sub-relativistic speeds. A defined region arou
Financial inclusion, defined as access and usage of formal financial services, has several positive micro and macro-level socio-economic implications. Due to decades of vigorous policies aiming at lowering barriers to formal finance, 80 percent of Indians now own a bank account. However, there is a significant gap between account take up and usage. One reason for low usage rate is persistent infor
The purpose of this thesis is to study complex analysis, the Bergman space and Korenblum's conjecture. This is done in three parts. In the first part the proofs that the conjecture is true are studied, giving lower bounds of Korenblum's constant. The first proof is explained in detail, to make it as accessible as possible to more people. The main differences for a couple of later proofs th
To investigate the differences in experienced stress and how this was moderated by the personality factors of work locus of control (WLOC) and extraversion between open plan-offices and activity based-offices (ABW), a questionnaire was sent out to the employees of nine different offices. 171 participants answered the questionnaire which consisted of five scales that measured perceived stress, dist
The objective of this study was to assess the influence of user behaviour on the Smart Grid performance and to identify possible interfaces between end-users and the energy network. In order to get an image of the electricity customers attitude to Smart Grids and energy-efficiency, a questionnaire was conducted as a first step. Afterwards, a combination of thermal building simulations and the deri
Stockholm har under de senaste åren visat stora hyresökningar på kontorsmarknaden samtidigt som bostadsmarknaden har avsvalnat. Även fast Sverige placeras bra i avseende på flera mått såsom vakans och BNP har städer som också haft bra tillväxt i BNP och låg vakans inte uppvisat lika hög hyrestillväxt. Den här studien undersöker fallet om bostadsmarknaden har påverkat kontorshyrorna i Stockholm. OmIn recent years, Stockholm has shown a large rent increases in the office market simultaneously as the housing market has cooled off. Although Sweden is well measured in several areas such as vacancy and GDP, other cities that also produced significant GDP growth and low vacancy rates have not shown as much rental growth as Stockholm. This study examines if and how the housing market has affected
The insurance industry is notoriously conservative and has seen comparably few technological improvements in the last fifty years. A wave of new technology- driven insurance firms, or insurtechs, is changing that. By leveraging new technology and offering more customer-centric and innovative products, these firms have captured shares in many insurance markets. One technology — yet to be broadly a
Abstract The care for the environment in investment situations is rising among different groups of investors, due to social and psychological factors. Existing studies on nonpecuniary preferences for the environment are focused on measuring the proportion of individuals with green agendas, whereas we focus on measuring also magnitudes, i.e. how much future wealth are people actually prepared to gi
Recent studies find that women are less competitive than men. This gender difference in competitiveness has been suggested as one possible explanation for why men occupy the majority of top positions in many sectors. In this study we explore competitiveness in children, with the premise that both context and gendered stereotypes regarding the task at hand may influence competitive behavior. A rela
Objectives: Pregnancy can influence immune control of Mycobacterium tuberculosis infection (MtbI). We recently reported an association between MtbI and pregnancy complications, particularly severe preeclampsia, in a registry-based cohort of women originating in tuberculosis-endemic countries screened for MtbI in Swedish antenatal care, implying a potential role of MtbI for the development of preec
Climate change can raise average temperatures and humidity and induce more frequent and stronger extreme weather events. This intensifies the need for studies on indoor climate and energy use in livestock buildings as it will affect animal welfare and farmers’ economy in terms of production, energy demand and needed investments. The aim of this review was to identify knowledge gaps and the need fo
Globular clusters (GCs) are among the oldest and densest stellar systems in the Universe, yet how they form remains a mystery1. Here we present a suite of cosmological simulations in which both dark-matter-free GCs and dark-matter-rich dwarf galaxies naturally emerge in the Standard Cosmology. We show that these objects inhabit distinct locations in the size–luminosity plane and that they have sim
