I många moderna tekniker med exempelvis robotar och förstärkt verklighet behövs tillförlitlig rörelsedata och kartor över omgivningen. Detta projekt fokuserar på att förbättra hur enhetens kamerariktningar, i en sekvens över tid, kan finjusteras efter sammanslagning av två eller fler sådana bildsekvenser, som initiellt roterats till att överlappa utan att deformeras. Genom att använda förhållandenMerging of maps, such as 3D point clouds obtained from Structure-from-Motion or visual SLAM, can enhance robustness and expand covered areas in applications like multi-robot systems or augmented reality. When direct data fusion is difficult, an alternative approach is to align pose trajectories. This work investigates the use of rotation averaging as a method for indirect map merging, especially f

The aim achieved through this thesis was to ascertain how much the pollutions of black carbon (BC) from each European country systematically deviate from their expected values obtained by inverting a transport model. The model used is based on meteorological observations as well as black carbon values obtained in the past at different locations. It was achieved by fitting a linear regression model

Urban planning has historically prioritized car traffic, often at the expense of pedestrian safety and accessibility. This study aims to explore how pedestrian behavior and preferences can be integrated into the design of more walkable urban environments. The purpose of this work is to identify specific pedestrian behaviors, such as shortcuts, that should be included in the planning of urban areas

Adaptation strategies can backfire and cause maladaptive outcomes, yet this is an understudied area in Swedish adaptation work, and a conceptually challenging theme with potential justice implications. The study explored the potential existence of maladaptation in Swedish municipalities in the Motala ström catchment area in collaboration with the FairWater research project, through conducting 18 q

Magnetresonanstomografi (MRI från engelskans, magnetic resonance imaging) är en bildtagningsteknik som låter oss avbilda kroppens morfologi och funktion, helt utan invasiva eller smärtsamma ingrepp. En av de funktionella metoderna är så kallat diffusionsviktad MRI (dMRI). Denna metod är känslig för slumpmässiga rörelsen hos de vattenmolekyler som finns i vävnaden. Eftersom rörelserna påverkas av sDiffusion magnetic resonance imaging (MRI) is a technique that utilizes the random thermal motion of water molecules to probe the microstructure of the tissue. Because it has excellent soft tissue contrast and high sensitivity to changes in the microstructure, it has established itself as a powerful tool to detect and quantify both normal development and pathological processes. Diffusion encoding

Bröstcancer är den vanligaste cancerdiagnosen bland kvinnor. I Sverige erbjuds alla kvinnor mellan 40-74 år regelbunden undersökning (mammografiscreening). Att upptäcka bröstcancer i ett tidigt skede har visats vara mycket gynnsamt för att kunna få effektiv behandling. Vid undersökningstillfället tas röntgenbilder av brösten, så kallade digitala mammografibilder (DM). I dagsläget utförs dubbelgranBackground and Aim: Artificial intelligence (AI) in mammography screening can aid cancer detection. Commercially available AI systems can assign region and exam scores based on malignancy suspicion. Despite promising suggestions, clinical implementation is limited- partly due to a lack of trust among radiologist and prospective evaluation. Inevitably, this leads to the question of how an AI system

Idiopatisk normaltryckshydrocephalus (iNPH) är en neurologisk sjukdom som påverkar hjärnans vätskecirkulation och kan leda till symtom som gång- och balanssvårigheter, kognitiv nedsättning och urininkontinens. Sjukdomen drabbar omkring 1.5 % av 70-åringar, och prevalensen ökar med åldern. Det är en svårdiagnostiserad sjukdom där hjärnvätska (CSF) ansamlas i hjärnans hålrum, vilket påverkar hjärnanIntroduction: Idiopathic normal pressure hydrocephalus (iNPH) is a treatable but largely underdiagnosed neurological condition affecting the elderly population. It is characterised by gait and cognitive impairment, as well as urinary incontinence. For the most part, it is diagnosed via imaging and clinical assessments. Abnormalities in cerebrospinal (CSF) flow in the cerebral aqueduct have been li

The transition to renewable energy and distributed energy sources is transforming power systems, increasing the need for active filtering systems to maintain power quality. This thesis presents a comprehensive study of control strategies for Active Dynamic Filters (ADF), focusing on how the control strategies: PI control, cascade control, direct feedforward, and passive damping can be used to dire

Kokvattenreaktorerna Barsebäck 1 och 2 togs i drift 1975 respektive 1977 och är sedan 1999 och 2005 avstängda. Nu är kärnkraftverket under avveckling och nedmontering, som innebär att alla byggnader som hör till Barsebäcksverket ska tömmas och rivas, vilket är en omfattande process. Det radioaktiva avfallet, så som använt kärnbränsle, ska förvaras i det svenska slutförvaret när det står färdigt, mThe decommissioning and dismantling of nuclear power plants (NPPs) require extensive radiation measurements to map contamination in concrete structures and other building materials and components. The vast amount of material to map consists of concrete. Accurate determination of the depth distribution of radionuclides, particularly easy-to-measure (ETM) gamma emitting radionuclides such as cobalt-

Global food systems are increasingly vulnerable to climate change, energy volatility, and geopolitical disruptions—threatening the security and stability of perishable supply chains. This thesis investigates the potential of aseptic packaging technologies, specifically ultra-high-temperature (UHT) treatment and sterile filling, as a means to reduce energy consumption and enhance resilience in the

This thesis explores the antecedents and consequences of introducing Artificial General Intelligence (AGI)-based agents into organizational teams, with a comparative focus on New Venture Teams (NVTs) and Established Venture Teams (EVTs) in the B2B SaaS sector. Drawing on the Input-Mediator-Output-Input (IMOI) framework, the study employs a multiple-case qualitative design, analyzing 14 semi-struct

This thesis establishes the first quantitative exploration on celebrity politicians and Philippine provincial development. The frameworks of patron-client-factions, caciquism and bossism, extracted from the established political dynasty literature are harnessed in order to establish the comparative impacts of four classes of provincial governors (dynast, celebrity, celebrity-dynast and regular) on

Engineering Education faces increasing demands to improve the quality of teaching and learning. At the same time, universities are described as slow-moving institutions and evaluations highlight recuring challenges. A key prerequisite for change is learning. This thesis aims to investigate the relationship between organisational learning and teachers’ decisions regarding course development in engi

Semantic search using large language models (LLMs) combined with an approximate nearest neighbor (ANN) index is the current state of the art in search technology. Semantic search aims to match a user’s search query based on its contextual meaning and intent with a highly relevant search result, rather than relying solely on matching keywords. While semantic search is superior to keyword-based sear

In robotic systems, uncertainty in model parameters, such as joint stiffness, link lengths, or mass distributions, can significantly affect performance and precision. This thesis investigates the quantification and propagation of such uncertainties using the programming language Julia, with a focus on developing a systematic framework for uncertainty-aware modeling and simulation. It leverages the

With the rapid diffusion of short video social media, a wave of rural influencers has emerged on China’s TikTok (Douyin), using short-form content to build personal brands and engage in sociocultural expression. Anchored in practice theory (Shove et al., 2012), this study adopts the “material–competence–meaning” triadic model to examine how these rural creators strategically construct personal bra
