In this thesis, we consider basic properties of Wilson lines, with special attention devoted to the renormalization and exponentiation property. We describe the generating function approach to non-abelian exponentiation and perform the calculation of the correlator of two and three semi-infinite Wilson lines meeting at a single point to two-loop order. We consider Wilson lines on lightcone and reg

The main hypothesis of this thesis revolves around the effects of changes in taxation of income on changes in the housing wealth of households. Two general conclusions arose from the analysis. Firstly, a percentage point increase in the top marginal income tax rate was associated with an economically significant decrease in regional inequality of housing wealth of households of 0.48 percentage poi

18 years has been past since Hong Kong returned to China in 1997, lots of policies and investment has been made to improve the regional integration and cooperation between Hong Kong and mainland China. Regional cooperation increased profoundly, and the region grew in a fast pace during the past two decades. The Hong Kong Shenzhen cross-border region is a special cross-border region case that exist

Problem/ background: Since the enlargement of the EU in 2004 and the free mobility directive there has been growing concern of homelessness and destituteness among EU migrants in several European countries, Sweden being one of them. This is an important welfare and policy issue. Previous research on this matter has tended to focus on challenges faced by, as well as strategies adopted by, NGOs and

Inom psykiatrin kan det vara nödvändigt att frånta en patient rättigheten att fatta beslut om sin egen vård. Syftet med denna studie var undersöka om demografiska faktorer bidrog till en godtycklighet i sjukvårdspersonals bedömning av en patients förmåga att fatta egna beslut. De faktorer som undersöktes var bedömarens kön, ålder, yrkesgrupp och antal yrkesverksamma år samt patientens kön. För attIn psychiatric care it can be necessary to deprive a patient of the right to make decisions about their own care. The purpose of this study was to examine if demographic factors contributed to an arbitrariness in health professionals assessment of a patient's ability to make decisions for themselves. The factors under study were the patient's gender and the health care professional’s sex,

Ternary semiconductor alloys like $In_xGa_{1-x}As$ have lured competing attention in connection to sub-50 nm high performance, low power, planar Complementary Metal Oxide Semiconductor technology. This compound semiconductor owes its popularity to excellent bulk carrier mobility, minority carrier diffusion constant, small bandgap, high electron injection velocity and its capability to take Moore&#

Det fanns två huvudsyften med examensarbetet. Det första huvudsyftet var att kartlägga energianvändningen för varje idrottsförening i Eslövs kommun. Det andra huvudsyftet var att genom fallstudier hitta energieffektiviseringsåtgärder som är typiska för idrottsföreningar, vilket inkluderade att visa på möjlig besparingspotential och lönsamhet i åtgärderna. I examensarbetet har även en studie gjorts

The frequency of two external cavity diode lasers tuned to the two transitions at 410 nm and 451 nm of indium are stabilized in this thesis. A hollow cathode lamp of indium atoms is used as a low pressure source of indium atoms in the locking process. Two frequency stabilization methods, wavelength modulation spectroscopy (WMS) and polarization spectroscopy (PS), are used in the thesis for the las

Barn- och ungdomsorganisationers syn och förhållningssätt till medlemskapet skiljer sig i jämförelse med andra ideella organisationer. Medlemskapets funktion och betydelse är fortsatt viktig men i arbetet för och med barn- och ungdomar framkommer att förhållningssättet till medlemskapet och dess dimensioner är mera flexibelt samt kan också uppfattas som ett hinder.

Att realisera outnyttjad potential – Om webbaserad samredovisning av BIM- och GIS-data En arkitekt placerar in sitt ännu bara tänkta hus i en realistisk 3D-modell av den omgivande staden för att visa allmänhet och beställare hur det kommer bli. En projektör lägger sin tunnel genom en tredimensionell geologisk karta och hittar snabbt och lätt tänkbara problemområden. Kart-appen på mobilen kan intCombined presentations of BIM- and GIS-data Throughout the process of creating and maintaining our built environment, from planning to building to facility management, large amounts of data are produced and consumed. Much of these are geographic data, processed in some form of GIS (Geographical Information System). Others are building data, increasingly handled in different BIM (Building Informati

Environmental problems commonly occur in the aftermath of natural disasters. If not managed properly, they jeopardise the success of the entire recovery process. The humanitarian sector has realised this threat and is looking for ways to properly mitigate environmental problems while maintaining their necessary flexibility. The conventional industry broadly uses environmental management systems (E

We have implemented an Intelligent Tutoring System (ITS) prototype for teaching multi-column addition and subtraction to children aged 5-10, using a digitalized version of the Montessori bank game exercises. An Intelligent Tutoring System is a piece of software that teaches a certain subject to its users, and that typically uses artificial intelligence related algorithms to personalize the educati

High Arctic wetlands are an important component of the global climate system. Nevertheless estimations of their expected response to climate change and associated climate-feedbacks have large uncertainties. Improving models for vegetation and carbon dynamics of ecosystems is an important step towards making predictions more accurate. In this study, an arctic-enabled version of the LPJ-GUESS dynam

Exchange rate volatility has been regarded as a vital macroeconomic concern for the policy makers and its impact on economic growth has gained much attention from the researchers in recent years. Existing studies tried to analyze the impact focusing on financial development. In contrast, we have given effort to examine it taking into account the trade dependence of the country. A panel of seven de

Unlike other environmental threats, the loss of biodiversity is irreversible and the current and rapid loss of species is alarming. Several authors agree the state-owned protected areas are not sufficient to lessen biodiversity loss which is accentuated because most of the biodiversity is on private land. In this thesis, I study private conservation’s role as a tool for biodiversity conservation a

Flying insects are able to negotiate complex environments such as tropical rainforests as well as less complex environments such as flowering meadows although little is known about how they avoid collisions while doing this. In this study, insect negotiation through holes was investigated using Bumblebees Bombus terrestris and Orchid bees Euglossa imperialis as test animals. This was done by allow

None of us are immune to the ongoing identity-processes. Identity formation is something that we are engaged in every day, both in our consciousness and our subconsciousness, from the society levels down to personal levels. This study examines how individuals with Assyrian background form their identities in Sweden. Questions on ”homeland” and ”home”, and statelessness are asked to contribute to t

I denna uppsats undersöks det om det finns en bostadsbubbla på den svenska bostadsmarknaden. Det görs med hjälp av de oberoende variablerna byggnadskostnader, befolkning och reporäntan för Stockholm, Malmö och Göteborg i en regression där en kvot mellan fastighetsprisindex och disponibel inkomst för respektive storstad fungerar som den beroende variabeln. Mitt ekonometriska resultat säger tyvärr i
