From Grassroots to Rooftops: Agency and the Right to Housing in Ugandan Housing Cooperatives

Amid a global housing crisis that leaves more than 1.6 billion people inadequately housed, dominant legal and policy frameworks still define “adequate housing” largely in terms of fixed outcomes such as tenure security, affordability, and habitability. This thesis argues that these lists overlook a critical dimension: people’s housing agency, the real freedom to shape their housing situation. Grou

A Study of γ-ray Polarisation Measurements Using COMPEX Ge-Detector Modules

A setup using two of the novel COMPEX composite Ge-detectors was assessed for its sensitivity for γ-ray polarisation studies. Two slightly different configurations were considered with angles of 90° and 180° between COMPEX 2 and COMPEX 3, using a standard calibration 60Co source. Measurements were performed with the two detectors in coincidence mode, and the resulting signals were digitised using

The Characterization of Myeloid Cells in the Tumor Microenvironment of Tonsillar Cancer Utilizing Low- and High Plex Fluorescent Panels

The immune cell population is essential for understanding the immune system’s reaction against the tumor. This study identified T cells and myeloid cells in human papillomavirus positive and negative tonsillar cancer biopsies via extracellular markers to investigate the biopsies’ composition, cellular neighborhood, and interactions. A detection method for tertiary lymphoid structure was developed.

Tredjelandschaufförer i Europeiska transportsektorn

Studien undersöker drivkrafterna bakom migrationen av tredjelandsmedborgare till Europa för arbete som lastbilschaufförer, samt deras arbets- och levnadsvillkor i Europa. Studien bygger på kvalitativa intervjuer med åtta förare från tredjeland samt fältobservationer i Sverige, Danmark och Belgien. Datan visar att ekonomiska incitament, såsom högre löner och möjligheten att försörja familjer i hemlThe study explores the driving forces behind the migration of third-country nationals to Europe for employment as truck drivers, as well as their working and living conditions while in Europe. The study is based on qualitative interviews with eight drivers from non-EU countries and field observations conducted in Sweden, Denmark, and Belgium. The data show that economic incentives, particularly hi

Beyond the Counter: Exploring Return Management as a Social Practice in Large-Scale Retail

This thesis explores how return policies are enacted and adapted in large-scale retail practice through the everyday work of employees. Using Social Practice Theory (SPT) as a theoretical framework, the study investigates how large-scale retail’s 365-day return policy is interpreted, negotiated, and performed by employees across different regional and organizational settings. While return managemen

Simple and general bounds on quantum random access codes

Random access codes are a type of communication task that is widely used in quantum information science. The optimal average success probability that can be achieved through classical strategies is known for any random access code. However, only a few cases are solved exactly for quantum random access codes. In this paper, we provide bounds for the fully general setting of n independent variables,

Spatial distribution of tertiary lymphoid structures in the molecular and clinical context of non-small cell lung cancer

Introduction: Tertiary lymphoid structures (TLS) are lymphocyte aggregates resembling secondary lymphoid organs and are pivotal in cancer immunity. The ambiguous morphological definition of TLS makes it challenging to ascertain their clinical impact on patient survival and response to immunotherapy. Objectives: This study aimed to characterize TLS in hematoxylin-eosin tissue sections from lung can

Protocol Fuzzing- A Comparison between LLM-Assisted and Mutation-Based Fuzzers

As the demand for secure software and hardware solutions increase in our modern digitalized society, the importance of reliable and cost-effective product testing is apparent. One such testing technique is fuzzing, which involves generating large amounts of malformed and randomized data to stress test system interfaces. This study aimed to compare traditional fuzzing methods to modern approaches a

Exploiting Ring Oscillators to Leak Secret Information

The manufacturing of hardware is a complex process where many different types of parties are involved. This creates risks of inserting hidden harmful parts, so called Hardware Trojans (HTs). HTs can have many different functions, such as reducing security, leaking information or degrading a system. This thesis examines how Ring Oscillators (ROs) can be exploited by a malicious party and modified t

TCCON observations as independent validation for in-situ inversion of surface CO2 fluxes with LUMIA?

Koldioxid (CO2) är den viktigaste växthusgasen när det gäller klimatförändringar. För att förstå och minska våra utsläpp behöver vi noggranna metoder för att spåra var koldioxiden kommer ifrån och hur den rör sig i atmosfären. Idag används nationella utsläppsrapporter, men dessa bygger ofta på beräkningar från företag och organisationer som kan vara svåra att verifiera; särskild för mindre nationeCO2 is the most important greenhouse gas in terms of radiative forcing, and it is therefore highly important that we can track our emissions and the effectiveness of carbon sequestration measures. While the national carbon inventories can be highly accurate, there is general conflict of interest, as national carbon inventories are bottom up estimates in part based on self-reportings from private a

Evaluating large language model adaptation strategies for geospatial code generation

Recent advances in Large Language Models (LLMs) offer a promising alternative by enabling code generation from natural language. However, despite progress, LLMs still struggle with spatial reasoning, structural fidelity, and robustness across diverse GIS datasets. This thesis systematically compares three LLM adaptation strategies, i.e., prompt engineering, retrieval-augmented generation (RAG), an

Estimating dissolved organic carbon in Lake Mälaren and Lake Erken, Sweden: A comparative study of spatial transferability and model generalisability using XGBoost and Sentinel-2 data

Accurate monitoring of dissolved organic carbon (DOC) in lakes is essential for understanding aquatic carbon dynamics, assessing lake ecosystem health, and supporting water resource management. While remote sensing offers scalable alternatives to in-situ monitoring, machine learning models often struggle to generalise across systems. This thesis investigates the potential of the eXtreme Gradient B

Shell-model Investigations in the p1/2g9/2 Space

The goal of the present work is to investigate possible improvements to established shell-model interactions concerning atomic nuclei in the mass A=90, N=Z regime. These investigations consist of generating energy spectra for the isotopes Pd-94, Cd-94, Ag-95, and Cd-95 close to the proton drip line, as well as an investigation of the transition probabilities between selected states in Ag-95. Data

Characterization of the HIBEAM time projection chamber prototype

The HIBEAM/NNBAR collaboration at the European Spallation Source (ESS) aims to discover processes of baryon number violation, such as neutron-antineutron oscillations, and it furthermore includes searches for sterile neutrons, ultralight axion dark matter particles, and nonzero neutron electric charge. The following investigation presents the characterization of the HIBEAM time projection chamber

An analysis of consumer value in a destination with a well-developed hotel industry after the pandemic of Covid-19: a case study on St. Regis Macao

In the post-pandemic era, the hotel industry is gradually recovering alongside the broader tourism sector. As a key component of tourism, hotel quality plays a vital role in shaping guest experiences. This thesis examines consumer value in the context of a well-developed hotel industry by focusing on the St. Regis hotel in Macao as a case study. The research investigates what types of consumer val

Membrane Distillation and Forward Osmosis for Pre-concentration of Thin Juice in Swedish Beet Sugar Refining

Betsockerprocessen är en energiintensiv process där ångdriven indunstning används för att avlägsna stora mängder vatten från den upprenade tunnsaften, som innehåller det från betorna extraherade sockret.
