Under de senaste 30 åren har migrationsförvar (Engelska: Detention centers) blivit metoden att föredra när det gäller hanteringen av migrationsströmmarna i flera länder inom Europeiska Unionen (EU). I samband med den ökade användningen har det även skett en förändring från att stater har ett slags monopol gällande hanteringen av migrationsfunktioner till att stater delegerar (Engelska: Outsource) In the last three decades, detention centers have become the preferred method to manage the migration flow in multiple states within the European Union (EU). In correlation to the increasing use of detention centers, there has been a shift from states having a type of monopoly on migration management functions, to an increase of states outsourcing their responsibility to private companies. When st

The city of Stockholm has increased its number of surveillance cameras in public places the last few years in the name of crime prevention. However, as the number of cameras increases, how does this affect the people living in the city? This paper examines how surveillance cameras affect young women between the ages of 18-24 and their perception in different area around Sergels torg, T-Centralen a

I den här rapporten undersöks möjligheten för att tillverka och använda gjutmodeller tillverkade genom additiv tillverkning, i folkmun kallat 3D-printing. Först görs en grundläggande analys över hur modellerna tillverkas idag och vilka krav som ställs på modellen. Detta innefattar både rena material och hållfasthetskrav, men även mer svårdefinierade krav där man enbart kan resonera kring rimliga aIn this report the possibility for the manufacture and use of molding-patterns made through additive manufacturing methods, commonly called 3D-printing, is evaluated. First an analysis of how the patterns are currently being made and which demands that are put on them will be made. This includes more pure material and load demands, as well as more abstract and hard defined demands. After this the

Education has the potential to play a critical role in the sustainable transformation of society which is needed to limit the consequences of the multiple ecological crises society is facing. While this has been recognised internationally at least since 1992, not a lot has been done within the Danish educational system to address issues of climate change, biodiversity loss, and sustainability with

Dark matter accounts for about 85% of all matter in the Universe, yet its particle nature remains unknown. The Light Dark Matter eXperiment (LDMX) is a proposed fixed-target missing-momentum experiment that intends to probe the predominantly experimentally uncharted MeV-GeV mass range for "light dark matter". A significant challenge for LDMX is to efficiently veto rare photo-nuclear back

Geographic Information Systems (GIS) are a powerful tool for supporting disaster risk reduction (DRR). International agreements such as the Sendai Framework for Disaster Risk Reduction call on high-income countries and other partners to support lower-income countries in strengthening their DRR capacities. This thesis explores the experiences of stakeholders in strengthening GIS capacities for DRR

This study examines the impact of sky-bridges, as an egress component, on total evacuation of a high-rise building by using an evacuation model named Pathfinder. Five scenarios, with different combination of aspects such as height of the building, number of sky-bridges (and the subsequent inter-distance between them), and people allocation have been simulated. The comparison between the results fr

Sensing temperature is important for identifying preferable temperatures and avoiding dangerous extremes. The cold pain limit of mammals in general is estimated to approximately 12 °C. I reasoned that such a skin temperature is unlikely to be sustainable in colder climates and studied cold-adapted dogs in northern Sweden using thermography. Skin temperature on the rhinarium (naked nose tip) was 2.

By way of a diachronic analysis the semantic changes of Japanese first person pronouns will be discussed. The goal of the analysis is to shine some light on the history and evolution of Japanese pronouns in the first person and in so doing show that these pronouns have been subjected to change semantically throughout history. To bolster the analysis research in the form of a survey has been conduc

We study a 1+1 dimensional Yang-Mills model in the light-cone gauge (the ’t Hooft model). The colour group is SU (N ) and we study the limit N → ∞, the limit is taken such that g²N is kept constant. In this limit the only contributing diagrams are planar diagrams without gluon-gluon interactions. Using this, it is shown that there are no free quarks in this model. The bound state wave equation is

Embedded systems are hard to debug and the field of control software testing is relatively unexplored. Progress in these areas could provide better testing heuristics and safer systems. More specifically, hardware emulation is a potentially powerful tool that can help improve the speed and quality of the development cycle. Therefore, this study developed a hardware emulator for supporting embedded

This work presents the first data from a calculation engine for synchrotron Microbeam Radiation Therapy (MRT) implemented in the EclipseTM Treatment Planning System from Varian Medical Services. The calculation engine constitutes a simple pencil beam algorithm estimating ‘peak’ dose and of Monte Carlo simulated Peak Valley Dose Ratios (PVDRs) that are used to obtain ‘valley’ dose. The aim of this

The number of devices connected to the Internet is rapidly increasing. Especially the number of Internet of Things devices. These devices contain software which, like any other software, needs to be updated. With the great amount of devices to update, this calls for a manageable updating solution which does not depend on user interaction. In this thesis we present a solution to dynamically update

The aim of this study was to optimize a function starch-ethyl cellulose film for targeting the therapeutically active substance to the colon in the disease state for patients suffering from inflammatory bowel diseases. This study includes: • The preparation of the polymeric films and the investigation of the characterization (for example mechanical properties, water uptake, dry mass loss, and mic

Sweden has seen an increased number of homeless EU citizens over the last years. There is no consensus among Swedish municipalities on how to handle the issue of housing for vulnerable EU citizens. The purpose of this thesis is to examine the right to housing and why vulnerable EU citizens cannot access the right. The issue is studied on three levels – human rights law, EU law and domestic Swedish

This master thesis was a project in cooperation with Höganäs AB. The aim was to increase the apparent density (AD) of two biomass chars, by three different agglomeration methods. The reason for the investigation is that biomass char could be used as a reducing agent in the sponge iron process at Höganäs AB. The goal was to exchange anthracite in the reduction mixture to agglomerated biomass char.

Matrix functions and their applications play an important role in different fields of science and engineering. The matrix exponential is one of the most important and extensively used function of matrices. The computation of the exponential of a matrix is an interesting topic that has been extensively studied over the years. There are several ways computing the matrix exponential but there is a pu

Gender diversity has gained a lot of attention in the corporate governance literature, reaching conflicting results whether board gender diversity has an impact on financial performance. As a consequence, we set out to investigate how board gender diversity affects financial performance through innovation using a mediation technique. We constructed three hypotheses grounded in the resource depende

The largest use of fossil petroleum is the production of fuels. Hence, finding sustainable alter-natives is an important step to reduce the emissions of greenhouse gases. One such alternative is to produce fuel from biomass, such as waste products from agriculture and the forest indus-try. In Sweden, the forest industry is an important part of the economy. The pulp mills pro-duce an excessive amou
