Simulation of Quantum Cascade Lasers

This thesis aimed to contribute to the improvement of Quantum Cascade Lasers (QCLs) by focusing on the effective determination of quantum levels in these devices. The current method relies on an outdated Fortran code, which poses challenges when integrating into optimization schemes. To address this issue, the thesis proposed the development of an improved version of the code using Python, thus en

Assessing the Efficiency of COLMAP, DROID-SLAM, and NeRF-SLAM in 3D Road Scene Reconstruction

3-dimensionell (3D) rekonstruktion, ett område inom datorseende, har under senare år gjort stora framsteg som en konsekvens av de omfattande genombrott som har skett inom Artificiell Intelligens (AI). Inom datorseende har man som mål att försöka förklara hur världen ser ut för en dator, där saker som vi människor finner uppenbara behöver beskrivas i detalj med matematiska begrepp för att datorn sk3D reconstruction is a field in computer vision which has evolved rapidly as a result of the recent advancements in deep learning. As 3D reconstruction pipelines now can run in real-time, this has opened up new possibilities for teams developing Advanced Driver Assistance Systems (ADAS), which rely on the camera system of the vehicle to enhance the safety and driving experience. This thesis pres

Electron-skyrmion systems, in and out of equilibrium, and isolated or contacted to reservoirs

A Kondo lattice skyrmion model in contact with a macroscopic environment is simulated to explore skyrmion dynamics, which is an extension of previous work. The system is simulated using non-equilibrium Green's functions within the generalized Kadanoff-Baym ansatz and the wide band limit. To get a time-linear scaling, we present an approximation to the collision integral, which offers a good tr

Water use efficiency in agricultural irrigation in Egypt: A qualitative study on the complexities of utilising fossil groundwater resources in the face of water scarcity

This study examines the adaptive capacity of desert farming in Egypt to imminent water scarcity and discusses the sustainability of fossil groundwater extraction. Through qualitative semi-structured expert interviews, the study identifies clear research and data gaps related to the Nubian Sandstone Aquifer System (NSAS) and highlights the need for a nuanced approach to fossil groundwater extractio

Avdelningen för integrerat logistikstöd (ILS) vid Saab Kockums Malmö har identifierat ett behov av att överskåda de nuvarande arbetssätten. Syftet med detta examensarbete är att undersöka de olika typerna av kunskap som är viktiga för arbetet på ILS-avdelningen, undersöka avdelningenComplex product development with long project times requires successful transfers of knowledge within and between projects. The department of integrated logistics support (ILS) at Saab Kockums Malmö has identified a need to oversee the current working methods. The purpose of this master thesis is to examine the different types of knowledge important to the work at the ILS department and explore th

Changing multinational organizations: Factors affecting organizational change

Multinational organizations operating in a changing business environment endure recurring reorganizational efforts. The process of changing a multinational organization is an ambiguous and complex activity. To achieve the desired outcome from an organizational change, factors affecting the change are highly relevant to regard and act upon. This thesis aims to identify and to understand what facto

Parasocial relationship building with AI influencers on Instagram

Parasocial relationships (PSR) are the driving forces in social media marketing and are, amongst other factors, the reason for social media influencers’ great success. However, in the last few years, a new form of social media influencer emerged, namely the artificial intelligence (AI) influencer. As the name suggests, these influ- encers are driven by AI programs and are therefore not real humans

Identification of epigenetic biomarkers associated with the development of diabetic kidney disease in individuals with type 2 diabetes: a nested cohort study

Introduction. Type 2 diabetes (T2D) is the most common type of diabetes, and it can cause complications such as diabetic kidney disease (DKD), the main cause of end-stage renal disease worldwide. There is an urgent need to develop new biomarkers that would improve DKD’s risk prediction in patients with T2D. This research aimed at identifying novel epigenetic biomarkers associated with future DKD i

Growing to thrive or growing to die? Analysing high-school students’ perspectives on the relationship between economic growth and environmental sustainability

How and what we should teach children about sustainability, in relation to our current economic system, has become the cornerstone of the debate on Education for Sustainable Development (ESD). This debate takes place in conjunction with a much broader debate on the concept of sustainable development itself, where the role of economic growth is both questioned and supported, seen as either a necess

Åtgärder för energieffektivisering av vanliga småhus - En teoretisk fallstudie av en 70-talsvilla

Bygg- och servicesektorn står idag för mer än en tredjedel av Sveriges totala energianvändning. Energifrågan ligger i fokus och samhället strävar efter en mer hållbar utveckling. Samtidigt ökar elpriserna vilket lämnar många hushåll med dyra räkningar för uppvärmning av sina småhus. En stor del av Sveriges småhus byggdes under 70-talet i samband med miljonprogrammet. Villabyggandet var som mest The construction and service sector currently accounts for over one-third of Sweden's total energy consumption. Energy issues are at the forefront, and society is striving for more sustainable development. At the same time, electricity prices are increasing, leaving many households with expensive bills for heating their houses. A significant portion of Sweden's houses were built during th

“Jag erkänner ett brott som jag i själ och hjärta anser mig vara oskyldig till.” - En kvalitativ innehållsanalys av politikers framställningar av egen brottslighet

De senaste åren har tre högt sittande svenska politiker gjort sig skyldiga till, eller blivit anklagade för, brott, vilket fått stor mediebevakning. Vidare är brottslighet i Sverige bland de mer framträdande politiska ämnena. Politikens inställning har under en längre period präglats av ett tufft förhållningssätt med hård retorik och känslostyrda förslag för att lösa ‘brottsproblemet’, som beskriv

How do rainfall patterns change microbial induced carbon dynamics in soil?

Climate change is changing the precipitation patterns around the globe, leading to more extreme weather events like severe drought and heavy rainfalls. These events are intrinsically related to soil moisture fluctuations, which strongly modulates carbon fluxes in terrestrial ecosystems. Studying the behavior of microbial communities present in agriculture soils during drying and rewetting events c

Inomhusklimat för simulering av hög boendetäthet i flerbostadshus

Under de senaste åren har trångboddheten minskat i de europeiska länderna, men i Sverige har trångboddheten istället ökat, framförallt i storstäderna. Det finns ett stående problem i det svenska samhället gällande trångboddhet som måste undersökas vidare, och hur dessa boenden påverkar konstruktionen av byggnaderna de bor i. Idag kan inomhusklimatet simuleras i datorprogram som WUFI Plus och IDA-IIn recent years overcrowding has decreased in European countries, but in Sweden overcrowding has increased, especially in the big cities. There is an ongoing problem in Swedish society regarding overcrowding that needs to be further investigated, and how these accommodations affect the design of the buildings they live in. Today, the indoor climate can be simulated in computer programmes such as W

Simulating metal ct artefacts for ground truth generation in deep learning.

CT scanning stands as one of the most employed imaging techniques used in clinical field. In the presence of metal implants in the field of view (FOV), distortions and noise appear on the 3D image leading to inaccurate bone segmentation, often required for surgery planning or implant design. In this research project, we focused on developing a pipeline to create a rich ground truth dataset, formin
