Accurate modeling of wireless channels in urban environments is crucial for the design and evaluation of communication systems. Geometry-Based Stochastic Channel Models (GSCMs) provide a balance between physical retings—an oversimplification that can reduce model fidelity.alism and computational efficiency by simulating Multi-Path Components (MPCs) through simplified ray tracing and stochastic sca
This master’s thesis explores the design of monopile foundations for a conceptual offshore wind farm in the Golfo de Cádiz, Spain. It uses a one-dimensional (1D) finite element (FE) modeling approach, based on the PISA-study. With the PISAstudy, new design models are available, which replace the traditionally used p-y method. A central part of this thesis is the Abaqus software, which is used to m
Mot bakgrund av ett ökat individualiserat arbetsliv och ökade krav riktas denna studie mot lärares kompetensutveckling i en sådan kontext. Studiens syfte är att öka kunskapen om lärares möjligheter till kompetensutveckling och hur lärare upplever och hanterar ansvaret för sitt eget lärande och utveckling i ett arbetsliv präglat av individualisering och ökade krav. Det mynnar ut i följande frågestä
This thesis examines how female-targeting fintech firms can internationalize in ways that genuinely promote financial inclusion for women. Conducted as an exploratory interview study with Female Invest, it builds on the broader observation that gender remains largely absent from fintech’s outlook. The study addresses two key research gaps. First, financial inclusion efforts often overlook how cult
The bulk of Norwegian offshore oil and gas platforms are self-sustained with energy, burning a portion of the extracted gas in turbines to power production. Replacing this energy with electricity from renewables – electrifying – has been put forward as a way to quickly slash domestic emissions. This, all while retaining and expanding fossil fuel production, whose lion’s share of emissions stem not
Biometric fingerprint recognition is a cornerstone of modern authentication systems, yet conventional convolutional neural network approaches often struggle with challenging cases, subjected to noise and partial overlap. This thesis explores the potential of transformer-based architectures to address these challenges. We design, implement, and evaluate five models on a large-scale dataset of over
To reduce reliance on energy-intensive, chemically synthesised nitrogen sources in microbial cultivation, we investigated the integration of the nitrogen-fixing bacterium Azotobacter vinelandii into a bioconversion process with the recombinant yeast Saccharomyces cerevisiae. Our objective was to develop a more sustainable approach by utilising biological nitrogen fixation to supply ammonium direct
Rangitoto är en vulkanö som ligger nordost om Auckland, Nya Zeeland, och tillhör Aucklands vulkaniska fält (AVF) som består av ca 50 utdöda monogenetiska vulkaner. Eftersom Rangitoto har egenskaper som skiljer sig från de andra vulkanerna i området tror man att området genomgått en förändring och gått in i en ny fas. Det var ca 500 år sedan Rangitoto senast hade utbrott och eftersom storstadsområdRangitoto is a volcanic island, located northeast of Auckland, New Zealand, and belongs to Auckland Volcanic field (AVF), which consists of c. 50 extinct monogenetic volcanoes. Since Rangitoto has characteristics that makes it different from the other volcanoes in the area, it is believed that the volcanic field has undergone a change and entered a new phase. Rangitoto had its latest eruption abou
Momentum or trend following investing refers to trading strategies constructed around the idea that in financial markets, the current trend will, more often then not, prevail. In the context of asset prices, this means that previous returns or the price development of an asset is indicative of similar future returns and price development. While at odds with established theory such as the weaker fo
Begun in 2010, the Lund-York-Cologne-CAlorimeter, LYCCA, collaboration is targeted at discovering exotic nuclear reaction products whilst implementing the possibility of both position tracking and measuring residual energies of relativistic particles. Each LYCCA module is composed of a double sided silicon detector and 9 CsI(Tl) detectors. This project is primarily focused on the Si detectors, the
Studiens syfte är att utreda huruvida likviditeten som helhet förbättrats till följd av införandet av MiFID II och dess medföljande förändring av tick-sizen på Nasdaq Nordics svenska huvudlistor. Studien genomförs på ett slumpmässigt urval bestående av 20 aktier från vardera tre huvudlistor med hjälp av historisk transaktions- och volymdata. För att testa för eventuella skillnader mellan periodern
Increase of urbanization and climate change are one of the factors that have been highlighted to influence the change of urban runoff hydrograph. This is resulting in an increase in peak flow within an urban watershed. Downstream flooding is the main problem that arises. To solve this, the sustainable urban drainage system techniques are adopted for reducing peak flow and increase baseflow. This t
Both studies on and the application of GIS-systems during several disastrous events has shown a potential of the technology to facilitate for decision makers to make quick and suitable decisions to limit the impact of an event. In Sweden the primary responsibility for a crisis is held by the municipality in which the crisis occurs, which motivates an interest in investigating how GIS can support m
The main objective of this study is to contribute toward a comprehensive understanding of the superradiance problem in a short wavelength regime ($100$ to $100$ eV). In this regime, superradiance is influenced by Auger effect which would compete with normal superradiance process, and we want to study if it is possible to generate ultra-short pulses on the femtosecond or attosecond timescale using
Virus capsids shows promise within a wide variety of applications. However, the current lack of understanding about their self-assembly limits their usefulness. A study of the amino acids relevant for their assembly would be of great use by giving insight to the mechanic behind it. Since the number of proteins involved in each capsid is so big, there is a need for a reporter system enabling easy a
One fifth of the energy consumed by buildings in Sweden is by those built before 1945, many of them constructed from solid masonry walls. Improving their heating energy consumption is a challenge we must face in light of human’s impact on climate change as well as increasing energy costs. Improving thermal performance can be achieved with many insulating materials however the environmental impact
Restidskvot används som ett mått över kollektivtrafikens attraktivitet, många kommuner delar viljan att göra kollektivtrafiken just attraktivare för att öka andelen resenärer. Stockholms län visade i en rapport för över 25 år sedan ett samband mellan restidskvot och kollektivtrafikandel. Den här rapporten undersöker huruvida ett liknande förhållande existerar för medelstora kommuner och hur det saTravel time ratios are a popular way to measure the attractiveness of public transport. There is a demand within the Swedish municipalities for ways to make public transport more popular and increase the number of passengers. This study investigates if a connection between the ratio of travel time and the share of passengers travelling by public transport can be shown for medium sized municipaliti
Genom att skildra 1930-talets och dagens tidsanda avser denna studie belysa hur den svenska folkhemspolitiken ändrat karaktär. Likheter och skillnader mellan de båda tidsandorna beskrivs för att belysa karaktärsändringen. Fokus ligger på områdena familj och bostad, med betoning på den senare. Exempel på likheter är hög arbetslöshet, bostadsbrist, låga nativitetstal, konjunktursvängningar och slago
In 1997 the Ugandan government introduced a reform program with the ambition to implement universal primary education. The abolition of tuition fees would ideally guarantee access to the public service delivery system as far as primary education is concerned and help to integrate underprivileged groups with the rest of the diverse society. The launch of universal primary education in Uganda implie
The focus of this report is flexible work forms defined as; broad and variating work, with a high degree off autonomy, participation, responsibility and freedom to organize the work process, and the opportunity to obtain personal and professional development. The aim of the report is to obtain a greater understanding of what impact flexible work forms has on the well being of the individual partic
