Behandling av avloppsvatten för att avlägsna ämnen som kan ha en negativ påverkan på den mänskliga hälsan och naturen är mycket viktigt innan vattnet återanvänds eller släpps ut i naturen. Intresset för anaerob vattenrening har ökat eftersom det är ett bra komplement till aeroba processer, samt för att det producerar energi i form av metangas. Målet med detta projekt var att undersöka hur olika dTreatment of wastewater is crucial for removing any compounds which can have a negative impact on human health and nature before the water is reused or released into nature. Interest in anaerobic treatment of wastewater has increased as it is a good complement to aerobic treatment, and it produces energy in form of methane. The aim of this project was to investigate how different operational para

Augmented Reality (AR) är på uppgång och många företag lägger miljontals dollar i branschen. Både Google och Apple har nyligen släppt sina egna AR SDK’er som kommer att köras på miljontals enheter inom en snar framtid. AR är verkligen fascinerande och har sagts vara nästa miljard-industri. Målet med denna avhandling är att undersöka vad som är möjligt med dagens AR för mobila enheter och undersökaAugmented Reality (AR) is on the rise and a lot of companies put millions of dollars into the industry. Both Google and Apple have recently released their own AR SDKs that will run on millions of devices in the near future. AR is really fascinating and have been said to be the next multi-billion-dollar industry. The goal of this thesis is to explore what is possible with today’s AR and what are th

Innovation är ett vidkänt koncept som har fått ökad betydelse i dagens organisationer. Uppmärksamhet har framförallt riktats till de initiala faserna av innovationsprocessen, kallade Fuzzy Front End (FFE). Att hantera FFE effektivt har blivit nödvändigt i utvecklingen av nya innovativa produkter, eftersom det kan minska cykeltider och kostnader relaterat till produktutvecklingen. Det är dock svårtInnovation is a widely known concept which has received increased importance in today's organizations. Attention has especially been directed to the initial phases of the innovation process, commonly referred to as the Fuzzy Front End (FFE). Managing the FFE effectively, has become essential in the development of innovative products, since it can reduce cycle times and costs related to product

Achieving the 17 Sustainable Development Goals (SDGs) depends on timely and reliable information. However, standardized methodologies and regularly available data exist for only 40% of the 232 indicators. The “Data Revolution for Sustainable Development” is supposed to bridge these data gaps by harnessing ongoing developments in information technology, particularly big data. Currently existing pil

This study explores the implications of an encampment policy - criminalising refugees’ mobility beyond the borders of a camp - for the potential of Cash Based Transfer assistance in protracted refugee situations. As the success of Cash Based Transfer assistance implies market availability and access to commodities, and certain interaction between the host community and refugee population, it is ar

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 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.

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

The Memorial Sloan Kettering Cancer Center (MSKCC) recommendations on prostate cancer screening were developed in response to three limitations of previous screening guidelines: insufficient evidence base, failure to link screening with treatment, and lack of risk stratification. The objective of the recommendations is to provide a schema for prostate cancer screening that maximizes the benefits,

Recently, the incentive structure facing doctoral students and researchers in economics has changed significantly in many European countries as a result of the adoption of the US approach to evaluating research output. This poses a threat to the development and position of the subject of economics in Europe since evaluation for promotion is characterised by an excessive focus on publishing in the
