Several findings show that dark matter makes up 27% of the universe. The goals of this thesis are to understand some of the most important evidences and candidates for dark matter, as well as how dark matter is searched for. The ATLAS and LDMX experiments are reviewed to give a greater insight into the search for dark matter. Two papers from ATLAS are studied more carefully and the data from these
During the last decades, extreme poverty has been declining globally while income inequality within countries has, in the developing world, been increasing. While the reduction of income inequality and poverty can be seen as crucial targets for development intrinsically, they might also have economic impacts. Existing empirical research and theory suggest that income distribution affects economic
While perovskite solar cells have become increasingly more efficient and popular, electrical characterisation of the semiconductor properties of perovskites has been limited due to the instability of the material. In this work, multiple approaches for creating such electrical test structures from perovskites are discussed. The chemical processing limitations for perovskites are laid out and common
Diabetes is a disease that is affecting more than 422 million people worldwide. Thiazolidinedinone (TZD) an insulin sensitizer is a drug used for diabetes type 2. It was first thought that the effect of TZD was through the nuclear receptor peroxisome proliferator-activated receptor gamma (PPAR- γ). Recently the mitochondrial pyruvate carrier complex (MPC) that can be found in the mitochondrial inn
In the last 30 years, a new mobile communications generation has been developed every 7 to 10 years. The last one that is currently under development is the Fifth Generation. This generation aims to fulfill a wide range of requirements for different use cases. To that end, a new radio access technology called New Radio (NR) has been developed. The main design principle behind NR is to allow enoug
Liposomes are closed spherical bilayered membrane structures in aqueous solutions, with an internal aqueous compartment entrapped by either a single or multiple concentric lipid bilayer(s). They can be used as a tool in research to mimic simple cell membranes, to study e.g. lipid-protein interactions, as well as they are extensively used as carriers of various molecules, especially for tumor targe
Multiple modern methods of statistical feature extraction and machine learning are applied to classification of encoding and retrieval of episodic memories using electroencephalogram (EEG) recordings. Raw data, different time-frequency methods, and multiclass common spatial patterns are used for statistical feature extraction. For each type of feature extraction multiple machine learning algorithm
Commutation Failures in LCC HVDC converters is a topic that is normally addressed from the component perspective, looking at converters’ internal signals. How these commutation failures affect the outer AC network is not deeply understood yet. This thesis will provide proof of how commutation failures causes abnormal behavior in the AC network, and how PMU data can be used in order to distinguish
The building industry in Sweden is dominated by concrete today. However, this material has a greater impact on carbon emissions compared to wood. By examining some of the general properties of wood and specifically cross laminated timber we have explored the basic advantages and disadvantages of this relatively new and mildly used building material, as well as, investigated why it has not develope
Over the past two decades non-representational and affectual geographers have cited the French philosopher Gilles Deleuze to the point of exhaustion. In this thesis I read Deleuze’s interpretation of Spinoza through the weird tales written by the American horror author H. P. Lovecraft to argue for a radicalization of the former’s work within geography. To this end I examine the often recognized, b
Recent decades have witnessed an innovation in genetics and biomedical practices, shifting the practice from treatment to prevention. Testing healthy individuals for genetic inherited diseases has now become increasingly common, preventing potential disease by offering early screenings, medication, or potentially surgery, reducing the genetic risk from developing into disease. Though, social scien
Eco-social policy seeks to provision welfare by upholding ‘social floors’ while operating within ‘ecological ceilings’, de-centering economic growth as a narrative of development. Advocates explore the role of policies integrating ecological and social goals in providing sustainable welfare. By focusing on Sweden, this thesis aims to explore the role of taxation as a tool for fostering change by a
A hydraulic system is designed to transport fluid power over large distances, from pumps to actuators where the fluid power is transformed to mechanical power. The submarines, built and designed by Saab Kockums, utilises such systems. There are, however, challenges as the hydraulic pumps consume much energy, and the system accumulators command significant space. As both energy and space are limite
This thesis analyzes schoolchildren’s mental health development in five mental health-related variables when they gain internet access through 3G networks. A unique panel dataset using the HBSC with country-level 3G coverage is constructed. Using a TWFE strategy to estimate the effect on the five outcome variables, a decrease in mental health is found for both female and male children. The results
The aim of this study was to investigate how adult attachment styles and emotional intelligence impact decision-making styles. An online survey was distributed to individuals aged 18 years or older (N =110). The survey included three instruments; the Adult Attachment Scale (AAQ), Wong & Law Emotional Intelligence Scale (WLEIS), and the General Decision-Making Style (GDMS) questionnaire, along
This thesis examines the impact of shareholder activism on the annual stock returns of targeted companies. Utilizing a dataset of activist campaigns from the FactSet SharkWatch 50 database, covering the period from 2005 to 2021, we investigate whether the presence of activist investors leads to enhanced stock performance. Our empirical analysis, employing an event study design, reveals a significa
Title: ESG procurement analysis - identification and prioritization of improvement opportunities Author: Tabea Sonnleitner Supervisor: Louise Bildsten, Division of Engineering Logistics, Faculty of Engineering, Lund University. Purpose: The purpose of the thesis is to investigate the ESG requirements of the case company, Company A, in order to create a prioritized improvement plan for the global p
There is uncertainty about whether AI-generated output can and should be protected under EU copyright law and, in that case, who should obtain the rights. This thesis examines this legal issue by interpreting the legal text especially the InfoSoc Directive, case law and by considering legal scholarships. It has been established in the thesis that an AI-generated output can be considered protectabl
