A large data set, consisting of 300 000 patients’ admission data to various intensive care units in Sweden, acquired from the Swedish Intensive Care Register, was used in this work. The aim was to enable accurate Length of Stay (LOS) and mortality within 30 days predictions by using feed-forward Artificial Neural Networks (ANNs). The LOS outcome was predicted as short versus long time stays, with
This research draws a parallel between the recent political backlashes witnessed in the (de)-industrialized world and people’s attitudes towards climate policies. In lieu of the rise of populism, subjective feelings induced by individuals’ perceptions of their condition have increasingly been considered by researchers. In parallel, there is a substantial literature on the determinants of public su
The observations of circumbinary planets have confirmed that these can in fact be stable. While previous studies on circumbinary planets have been done, not many have been made on systems containing multiple circumbinary planets on eccentric orbits. In this thesis, the effects a binary star system of solar mass would have on the Solar System is investigated. Using the program MERCURY, numerous int
In this thesis we investigate the application of spatial coupling in turbo equalization. We show that with spatial coupling we can have a fresh perspective on the trade-off between performance in the waterfall and error floor region often encountered in the choice of codes for turbo equalization. Describing turbo equalization in the perspective of message passing on factor graphs, we show various
Problem solving skills are highly related to later life success. Several factors can influence these skills and their development, for example the level of executive function (EF) as well as individual temperamental features. This study examined problem solving performance among young (22-60 months old) children in a cross sectional design. The aim of the study was to explore how different compone
The purpose of this study is (1) to investigate the direct influence of femvertising on female consumers’ attitudes towards the ad, brand gender perception as well as purchase intention and (2) to test the indirect effect of femvertising through attitudes towards the ad and brand gender perception on purchase intention. This study used a random independent group design, assigning the survey respon
Studien granskar de kontrasterande bilder av Karl Marx teorier och marxismen som ges av sociologiutbildningar på svenska universitet. Genom intervjuer med undervisande sociologer och en litteraturstudie över den vanligaste introduktionslitteraturen visar jag några centrala skiljelinjer inom sociologin. En riktning främst representerad av Anthony Giddens & Philip W. Suttons bok Sociologi (2014)This study reviews the contrasting images of Karl Marx theoretical output and of Marxism offered by sociology courses at Swedish universities. By means of interviews with lecturing sociologists and a literature review covering the most common introductory textbooks I demonstrate some central dividing lines within sociology. One tendency is foremost represented by Anthony Giddens’ & Philip W. S
Hypothyroidism is a common disease involving diverse physical, cognitive, and emotional symptoms impacting many aspects of functioning. The indicated treatment produces significant improvements but leaves many with residual symptoms that significantly impair functioning. Numerous patient surveys reveal high levels of dissatisfaction with the treatment and healthcare professionals. Less well unders
Examensarbetet ämnar att utvärdera användning samt utveckling av en "intelligent uppvärmning" för ett hus. Genom att kontrollera strömbrytare, kopplade till en säkring, kan olika tekniker som kan användas för en självlärande algoritm utvärderas. För tillfället måste användarna själva försöka förutsäga hur lång tid en uppvärmning kommer att ta. Den utvecklade algoritmen ska hjälpa användaThis report aims to examine the use and development of a more intelligent heating process in a house. By controlling switches integrated into a fuse, the techniques that can be used to allow an algorithm to predict how long the heating process would take are evaluated. Currently users have to, themselves, estimate how long the heating process will take. The algorithm developed aims to alleviate th
Timing of phenological events are highly related to climate and is one of the first signs of ecosystem responses to the climate change. Timing of flowering phenology is an important trait influencing the distribution and fitness of plants species. Tundra ecosystems are particularly important to study these effects due to short growing seasons, poor pollinator community and a particularly pronounce
Operant conditioning is a psychological theory about learning through positive and negative reinforcement which has been researched for decades. However, some fundamental components of this theory have not yet been thoroughly researched, such as its interaction with long-term retention and context. These components are essential if we want to understand how operant conditioning applies in everyday
The aim of this master thesis was to develop adaptive control for a quadrotor using Gaussian process regression (GP). Online regression with GPs can provide many benefits as it is a flexible non-linear regression model that can provide uncertainty measures of the estimate. However, online GP regression may also gives rise to problems. Because of the high numerical complexity of GPs, sparse approxi
Syfte: Syftet med denna studie är att undersöka om det finns några skillnader mellan hur företag i Sverige respektive Tyskland rapporterar om FN:s globala mål för hållbar utveckling. Vidare ger uppsatsen exempel på möjliga förklaringar till resultaten. Teoretiska perspektiv: Genom att kombinera två välkända teorier, nämligen legitimitets- och intressentteori, samt Varieties of Capitalism som en ko
Interactions play a crucial role in determining how galaxies evolve in terms of their morphologies and star formation histories, since the majority of the known galaxies in the nearby Universe are found to exist in groups. Compact groups of galaxies are of particular interest as they contain a small number of galaxies in dense configurations and host repeated interactions between them, enabling us
This thesis investigates internal migrant selection and migrant sorting among the Brazilian working age population between 2007 and 2014. The study tests the validity of the Borjas model, that predicts variation in migration probability across education levels. A twofold empirical analysis is performed. In the first step, a logit model is used to analyze migrant selection. The results suggest that
This study assesses the performance of buildings affected by climate change under future climate predictions for three time-periods until the end of the 21st century. Objects studied are residential multi-storey buildings, originally built before 1970 and retrofitted during the last decade. A total of four actual retrofit projects, as they were performed, in Denmark and Germany were assessed in th
Analogisk överföring undersöktes hos förskolebarn (24 månader till 55 månader) med en faktoriell tvärsnittsdesign. Analogisk överföring testades direkt efter inlärning eller ett dygn senare med en visuo-spatial uppgift. Vidare testades de kognitiva förmågorna arbetsminne, inhibering, självreglering och verbal intelligens. Studiens hypoteser var att fler barn skulle klara den direkta överföringen äAnalogical transfer was studied in preschool children (24 months to 55 months) with a factorial cross sectional design. Analogical transfer was tested directly after learning and one day later, using a visuospatial task. The cognitive abilities working memory, inhibition, self-regulation and verbal intelligence was assessed. The hypotheses were that more children would pass the direct condition th
Amelogenin, a protein that takes part in enamel development, has some interesting physicochemical properties such as the formation of nanospherical aggregates. Furthermore, its derivatives have shown regenerative properties and have already been commercialized for that purpose. Therefore, it was of interest for this project to evaluate mammalian cell attachment and proliferation on engineered vari
