Background and purpose: Stereotactic radiosurgery (SRS) requires high positional accuracy to safely deliver large doses. This study evaluated an integrated surface- and image-guided radiotherapy (SGRT-IGRT) system by analysing (1) the agreement between thermo-optical and stereoscopic X-ray positioning, and (2) the impact of intra-fractional workflows on treatment accuracy and time. Materials and m
We show exponential lower bounds on resolution proof length for pigeonhole principle (PHP) formulas and perfect matching formulas over highly unbalanced, sparse expander graphs, thus answering the challenge to establish strong lower bounds in the regime between balanced constant-degree expanders as in [Ben-Sasson and Wigderson’01] and highly unbalanced, dense graphs as in [Raz’04] and [Razborov’03
The Sami people have a long history of colonization, discrimination, marginalization and prosecution in their past. My thesis deals with how the Sami identity is created and reproduced today and how it has been shaped in the light of the history of the Sami people and the policies pursued by the Swedish government through times, and also why the search for identity, heritage and roots has had such
The aim of this study is to 1) describe the structure and types of associational and organizational networks within immigrant women’s community in southern Sweden Malmö, Lund and Eslöv, 2) examine how such networks facilitate Thai women’s well-being and integration by providing social supports and services, and 3) present how Thai women perceive the role of social and organizational networks in re
This thesis aims to address a dual crisis. Globally, the construction industry relies on a linear “take-make-dispose” approach and a “tabula rasa” tactic in each novel project, draining the Earth’s resources. Locally, around a half of residential buildings in Riga, Latvia, are of Soviet mass housing typology. These structures are on the verge of structural expiration, at risk of progressive collap
Artificial intelligence (AI) is playing an expanding role in infectious disease surveillance and intervention planning by enabling analysis of large-scale health data. One of the key challenges in this area is to characterize transmission within households and to identify factors that influence both infectivity and susceptibility. The present study focuses on the COVID-19 pandemic, which not only
Transitioning from linear to circular production systems requires interactions that include cross-sectoral collaboration in networks. Understanding the role of collaboration within these networks can support the transition to a circular economy. To understand cross-sectoral collaborative endeavors, this paper develops a collaboration framework for circular economy by combining and interlinking thr

In recent years, land acquisition has escalated due to increased global demand for food and fuel driven by population growth, urbanisation, and growing energy demand. Mozambique is ranked as one of the world’s top 10 countries with available land for agriculture, forestry and livestock production. Low labour costs and land taxes may further increase the interest in Mozambican land. In particular,
Intra locus sexual conflict (IASC) occurs when sex-specific optima for a certain trait differs, and the trait is controlled by shared genes across the sexes. Sexual dimorphism is recognized to be a sign of previous or ongoing sexually antagonistic selection in separate sexed species, while hermaphrodites have been overlooked in the past due to their monomorphic appearance. Despite this, hermaphrod
Oats have been gaining huge popularity in the past three decades, due to its well-known positive effects in serum cholesterol levels, glucose homeostasis and insulinemia. A growing body of evidence shows a link between obesity, metabolic dysfunctions and gut microbiota composition. The main objective of the project is to develop an oat bran and milk based fiber-rich beverage and an oat based yogur
Classification of surfaces in the near field using millimeter-wave radar commonly considers the use of polarization based methods for road condition monitoring. When a surface consists of larger structures one instead wishes to monitor the surface topography. Analysis of scattering from rough surfaces is highly complex and relies on prior knowledge of surface structure. In this work a device movin
Using a microcontroller unit to implement different machine learning algorithms for myoelectric prosthesis control is currently feasible. Still there are hardware and timing constraints that need to be accounted for. This master thesis presents results from automatically generated Arduino code for some Neural Networks, Convolution Neural Networks and linear machine learning models that was impleme
Downstream processing is an essential part in the production of biomolecules and the optimization of these processes are of great value, since they can be both time consuming and expensive. One common type of enzyme used in different biotechnical approaches is proteases and in this study Protease X was investigated. In order to use the enzyme in a process, a purification procedure needs to be esta
Kunskap om markens uppbyggnad är viktig både för konstruktions och prospekteringsändamål. Geofysiska undersökningsmetoder kan användas för att skapa en överblick att basera vidare undersökningar på. I den här studien används likströms resistivitet och inducerad polarisation, IP. Datan är inverterad med en Cole-Cole modell i programmet ÅrhusInv och använd för att karakterisera berggrunden vid ÖnnesFor both construction and exploration purposes, knowledge of the subsurface is important. Geophysical exploration methods can be used to acquire an overview of an area on which further investigations can be based. In this study direct current resistivity and induced polarization data, inverted with a Cole-Cole model in program AarhusInv, are used to characterize the bedrock at Önneslöv in Scania,
The purpose of this thesis is to determine how electric vehicle trucks can meet the needs of customers in the urban building and construction sector. This sector contributes significantly to greenhouse gas (GHG) emissions, and also creates noise and other disturbances in urban environments. There are multiple benefits that come with electric trucks, which can address these issues if they are used
Förenta Nationernas fredsbevarande operationer har under nästan två decennier besvärats av anklagelser om sexuellt utnyttjande av och sexuella övergrepp på civilbefolkningar. Flera rapporter visar inte bara att organisationens fredsbevarande styrkor begår dessa brott mot just de människor de fått i uppdrag att beskydda, utan också att de undgår ansvar och straff. Denna uppsats undersöker och utvärUnited Nations peacekeeping operations have, for the better part of two decades, been plagued by allegations of sexual exploitation and abuse of local civilian populations. Several reports indicate not only that peacekeepers exploit and abuse the very people they were sent to protect, but also that these crimes routinely go unpunished. This thesis examines and evaluates the different methods of ho
Due to the focus of their study program, environmental and sustainability students are vulnerable to experience negative emotional impacts, potentially affecting their mental health. This thesis contributes to increased understanding of emotions and emotional resilience in relation to the climate crisis by examining experienced emotions, studying the power students have over their emotions, and po
As the need to adapt to a changing climate and the political rhetoric in this regard are growing, Berlin’s Senate has issued strategic policies – complemented by an increase of funding. Berlin’s socio-cultural features and place-based factors seem predisposed for so-called “Nature-based Solutions” (NbS) that can support the achievement of adaptation efforts. This encouraging context seems to be co
