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. The task we constructed was to detect Canisters and whether they feature a protective valve called a Cap or not (called a No-Cap). The problem was split into three separate classes in order to evaluate objects with varying si
Reclaiming the Past and the Present: The Presentation and Representation of Ethnic Minorities in Cultural Institutions
Cultural institutions such as museums and art galleries are important agents in educating the broader public on matters where current awareness is missing, inadequate or inaccurate. In this study, I focus on one such matter, which is the knowledge regarding ethnic minorities, their history, traditions, and current challenges. 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
Spectrally resolved insect flashes by sunlight
Insects are vital for the environment and biodiversity. Optics-based remote techniques can quickly and effectively identify and track insects in their natural habitat. This has the potential to speed up and improve the time-consuming process of manually monitoring insect diversity. This thesis presents a method to remotely sense insects by analyzing the sunlight reflected by free-flying insects. T
Autonoma Vapensystem och folkrätten - Problem, definition och överblick
Den här uppsatsen går igenom Autonoma militära system och dess unika utmaningar för den internationella rätten. Med ett fokus på användning, och utveckling av dessa inom ramen för krigets lagar angående ”jus bello”. Upp-satsen utreder ocskå frågan om vilken definition som bör användas, om det åligger ett s.k. ”responsibility gap” som är unikt för AMS och hur detta för-håller sig till frågan om indThis paper examines the issue of autonomous military systems and their unique challenges for international law, with a focus on the use and develop-ment of these systems in the framework of international regulation regarding “jus bello”. It also examines the issue of which definition of “autonomous military systems” should be used. The paper examines the question if there is a so called “responsib

Exploring the Placement of Gambling Problems within the Hierarchical Taxonomy of Psychopathology
Gambling problems often coexist with various psychopathological conditions. The Hierarchical Taxonomy of Psychopathology (HiTOP; Kotov et al., 2017) offers an empirically based model to structure psychopathological symptoms into broader dimensional spectra, including internalizing (anxious-depressive), externalizing (impulsive-aggressive), and thought disorder (dissociated-psychotic) symptoms. The

Natura 2000-områdens roll i omprövningen av vattenkraftens miljötillstånd
Vattenkraften utgör ungefär 45 % av Sveriges elproduktion och har varit en stabil energikälla med lågt koldioxidutsläpp under lång tid. Med ett allt större inslag av intermittenta energislag i elsystemet, fyller vattenkraften också en viktig funktion med sin reglerförmåga för balansering. Trots sina fördelar som en lagringsbar energikälla är det tydligt att vattenkraften har negativa effekter på SHydropower stands for around 45 % of Sweden’s electricity production and has been a stable energy source with low carbon emissions for a long time. With increasing share of intermittent energy sources in the electricity system, hydropower also plays a crucial role in balancing the grid. Despite its advantages as a storable energy source, it is clear that hydropower has negative effects on Sweden’s
