Real or Perceived? When powerlessness hinders climate policy support. The France of the Yellow Vests: an application.

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 Solar System Around a Binary Star

Vår stjärna solen är långt ifrån den enda i universum. Det finns enorma mängder stjärnor bara i vår egen galax. Man har upptäckt att en stor andel av av stjärnor existerar i binära par, det vill säga två stjärnor som kretsar kring varandra. Dessutom har nya observationer med hjälp av KEPLER teleskopet under 2010-talet har visat vad man endast har kunnat spekulera om i flera årtionden: planeter kanThe 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

Spatially Coupled Codes in Turbo Equalization

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

On the selection of increments in Jacobian approximations for numerical solvers of ordinary differential equations - An experimental study

Inom matematik så används något som kallas derivator för att beräkna förändring. Ett exempel är hastighet som är positionens derivata. När man uppskattar hastighet så dividerar man förflyttningssträckan med tidsåtgången. För att ge en mer precis uppskattning för hastigheten i stunden så kan man då minska tiden man beräknar över. När detta görs på datorer så stöter man på problem när stegen blir föSome numerical methods approximate the Jacobian using finite differences as part of their process. The finite difference method of approximation resembles the limit definition of the derivative. Since a computer cannot handle the mathematical concept of limits, a sufficiently small number has to be chosen as an increment. However, when the increments are chosen outside of certain acceptable ranges

Kan jag skylla på föräldrarna? En kvantitativ studie om kopplingen mellan anknytning, moral och brottslighet.

Den aktuella studien är en kvantitativ enkätstudie grundad i Anknytningsteori och “Age-graded theory of informal social control" som ämnade att undersöka kopplingen mellan anknytning, moral samt kriminalitet. Studien testade de tre följande hypoteserna; Låg moral och generell otrygg anknytning predicerar tillsammans en intensiv kriminell karriär i högre utsträckning än endast generell otrygg The current study is a quantitative survey based on attachment theory and age-graded theory of informal social control with the purpose of investigating the connection between attachment, morality and crime. The study has tested three hypotheses; Low morality and general insecure attachment together predicts an intense criminal career more than insecure attachment alone. An insecure attachment to

Towards Automated Log Message Embeddings for Anomaly Detection

Log messages are implemented by developers to record important runtime information about a system. For that reason, system logs can provide insight into the state and health of a system and potentially be used to anticipate and discover errors. Manually inspecting these logs becomes impractical due to the high volume of messages generated by modern systems. Consequently, the research field of mach

Using Synthetic Data For Object Detection on the edge in Hazardous Environments

This thesis aims to evaluate which aspects are important when generating synthetic data with the purpose of running on a lightweight object detection model on an edge device.

My primary focus is on how cultural institutions utilise their exhibitio

Data Augmentation for Object Detection using Deep Reinforcement Learning

Data augmentation is a concept which is used to improve machine learning models for computer vision tasks. It is usually done by firstly, defining a set of functions which transforms images and secondly, applying a random selection of these functions on the images. Since the quality of training data is one of the, if not the most important factor to obtain a good model, this master thesis poses th
