The aim of this master thesis was to develop a rotation-based collimation system for large coaxial high-purity germanium detectors for use in intense radiation fields. A collimator was constructedformed as a cylinder surrounding the detector, with a 90° slit opening to the detector. The rotational asymmetry caused by the slit was used to trace the direction of the incident gamma rays as well as re

In online auctions bidding frequency tends to increase towards the last minutes of the auction. This thesis investigates why bidders might choose to engage in last minute bidding, sniping, in Tradera auctions (Tradera is a Swedish subsidiary of eBay). Tradera uses a hard-close rule and a second-price rule. In hard-close auctions the dead-line occurs at a specific time, after which new bids are not

Purpose: Radiotherapy of moving tumours is a great challenge in cancer treatment. The moving target will lead to “dose-smearing” of the planned dose distribution and a need for larger margins. To reduce the dose to the surrounding healthy tissue, while still ensuring full coverage of the target, other methods for motion compensation is needed. Inversely optimised arc radiotherapy, where the treatm

The theory of Market Microstructure Invariance proposed by Kyle and Obizhaeva (2010) is presented and tested on spread data for bond futures. The data used are transformations from over 150,000 observations of futures on German government debt securities (Schatz and Bund) and 10-year US treasury notes. To account for the possible presence of long memory processes, we perform a GPH-test that displa

The capacity of an emergency response system is a deciding factor in its design and development, as well as its consequent success. Given this perspective, it is obvious that it is meaningless to do a risk analysis of a system without examining or knowing its capacity first. But how is capacity evaluated? A literature study was done to find existing methods and it revealed that capacity is a conce

Using a master’s-level human rights program funded by Sweden at Peking University, this case study sought to explore the connection between legal education and social change as influentially advanced by the Law and Development Movement (LDM) and now reflected in various donor-funded law and governance projects in China. To evaluate the program’s underlying assumptions of change, the study examined

This thesis treats the effects of various factors on the price development of agricultural estates in Sweden. An econometric approach is used to determine the impact, the factors included are chosen with regards to extensive interviews with people with industry insights and long experience of the business. The purpose is to describe and analyze the price development over time. Our results indicate

Uppsatsen syftar till att beskriva och analysera individers reaktioner i förändringsprocesser och omfattar en presentation av två perspektiv. Inledningsvis presenteras ett Change Management perspektiv, där motstånd, såsom t ex kritik mot förändringen, via en omfattande litteraturstudie visat sig vara den dominerande synen på individers reaktioner i förändringsprocesser. Motstånd är därtill något s

China has the world’s largest telecommunication market and the competition in this market is becoming fiercer among corporations. To survive and increase market shares, competitive advantages are the key factors each corporation strives for. As one of the representative companies in the industry, China Mobile established in 2000, with its competitive advantages, has expanded rapidly and led to hug

In today’s financial markets, the estimation of implied volatility of options plays an important part. Through the options prices, the implied volatility shows the size of market movement that is anticipated by the market’s participants. It is used as a benchmark for pricing all kind of assets and an erroneous number can be very costly. There are several methods for estimating and establishing pat

I juni 2011 antog ILO konventionen om goda villkor för hushållsarbetare. Konventionen fastställer anställningsvillkor och arbetsrättigheter för hushållsarbetare. Hushållsarbete sker, till skillnad från andra former av arbete, i privata hem utan insyn från det offentliga och är ofta ett ensamarbete. Detta innebär att hushållsarbetare riskerar att bli utsatta för missförhållanden och exploatering. KIn June 2011, the Domestic Workers Convention was adopted in the ILO. The Convention establishes minimum conditions of employment and labour rights for domestic workers. In contrast to other types of work, domestic work takes place in private households, in isolation and hidden from public insight. This makes domestic workers vulnerable to abuse and exploitation. The Domestic Workers Convention ob

The present thesis deals with the unsatisfactory access of the blind and visually impaired persons to accessible copyrighted materials as part of the clash of human rights and intellectual property rights. Therefore, numerous human rights of these groups of people affected by the lack of access to copyrighted works are studied. Finally, the World intellectual Property Organisation Draft Treaty for

Syftet med uppsatsen är att undersöka och förklara vad som påverkar valet av företagsform. De bakomliggande faktorerna kartläggs, såväl sociala som ekonomiska, och därigenom förklaras vad det är som avgör att entreprenören slutligen väljer aktiebolag, handelsbolag eller enskild firma. För att uppnå syftet med uppsatsen har en deduktiv metod med induktiva inslag använts. Hypoteser har utvecklats so

Syftet är att kartlägga och analysera hur noterade telekombolag, verksamma i Sverige, redovisar flerkomponentsavtal. Vidare utreds huruvida det finns behov av ökad vägledning i IFRS för detta redovisningsområde. Avslutningsvis sammankopplas dessa två dimensioner med vilka upplysningar som lämnas och vilken påverkan organisationsspecifika interna faktorer har. Ett kvalitativt synsätt har använts fö

In this essay I have done an analysis of a text by Nick Arnold who is a writer of children’s books about science with the ambition to make science accessible to everyone, and especially to children. I have translated the first 6 000 words of his Measly Medicine(2006), looked into different methods of explanation he uses in order to make difficult subjects available to children, and analysed what I

This thesis examines the role of mobile access to virtual worlds in massively multiplayer online role playing games (MMORPG:s). Online gaming worlds have existed for decades, but ever since the smartphone has become more common, new interaction possibilities to these worlds have emerged. We have conducted a literature review to clarify existing gaps in the research community regarding mobile virtu

Due to the human population, urbanization and the standard of living is increasing, the municipal solid waste is increasing in the same pace. While the society overall is getting more environmentally conscious and getting a better insight in the consequences of not managing the waste that is produced in a better way than dumping it on deposits, problems arise and especially in larger cities. Big p

Syftet med uppsatsen var att jämföra antalet kvinnliga respektive manliga författare som elever i den senare delen av grundskolan får kännedom om. För att undersöka det använde jag mig av läroböcker i svenska riktade till årskurs 7-9. Antalet författare i alla undersökta läroböcker räknades samt viktades på olika sätt. Först efter hur många gånger de nämndes i läroböckerna och därefter efter hur m

Lagstiftningen om de ideella rättigheterna namngivelserätten och respekträtten skiljer sig mycket åt mellan Sverige och USA. I Sverige är dessa rättigheter en del av upphovsrätten och tillkommer alla verk som uppfyller kravet på verkshöjd. De ideella rättigheterna kan inte överlåtas utan kan enbart efterges med en bindande verkan till ett användande som är begränsat i art och omfattning. Ledstjärn
