The self-screening error in the GW approximation is studied by applying correction schemes beyond the random-phase approximation in model and ab inito calculations. Two model systems in the form of Hubbard dimers, with one and two orbitals per site respectively, are considered. Both the self-screening (GW-ss) and self-polarization (GW-sp) correction schemes are compared to ordinary GW calculations
The aim of this exploratory research has been to examine the lean startup methodology process and foster a better way of applying this method in the global south. This is done by assessing the method’s application process of a solar startup targeting the Kenyan market - the strengths and weaknesses the company encountered during the process, measures taken by the company to overcome those weakness
Racial profiling is something that has been occurring in different contexts and countries for decades. When discussing the topic, it usually refers to the police authority conducting direct or indirect racial profiling of individuals who seem suspicious or that have foreign appearance compared to the native population. My focus is specifically on the recent debate of potential racial profiling by
Malmö stad har i sin översiktsplan från 2018 fastlagt att utbyggnad ska ske som förtätning innanför Yttre Ringvägen. Vidare prioriteras enligt planen förtätning i stationsnära lägen. Därutöver återöppnades den gamla Kontinentalbanan i Malmö, i december 2018. Längs med denna järnväg syns områden som i linje med den översiktliga planeringen skulle kunna ha förutsättningar för förtätning. Med grund i
Trä är ett av våra äldsta byggnadsmaterial. Idag återfinns trä ofta på många olika platser i en byggnad och fyller således många olika funktioner. Fuktinnehåll i trä påverkar dess mekaniska egenskaper och vid höga fuktinnehåll är sannolikheten stor att trä angrips av biologiska organismer. Det är därför viktigt att skydda trä mot fukt och även mot variationer i fuktinnehåll. Traditionellt har trycWood is one of the oldest and most known building materials. Today wood can be found in many constructions and fill different type of functions. The moisture content in wood affects the mechanical properties and at a high moisture content there is a risk of attack by biological organisms. Thus, it is important to protect wood from water. Traditionally pressure impregnated wood has been used in dam
Syftet med studien är att undersöka sambandet mellan olika riskfaktorer och riskpremiens storlek i företagsobligationer utgivna av nordiska bolag under tidsperioden 2013-2018. För att undersöka studiens syfte används en kvantitativ metod med deduktiv ansats. Studien utgår ifrån tidigare forskning som undersökt vilka riskfaktorer som påverkar storleken av en företagsobligations riskpremie på andra The purpose of this thesis is to investigate the relationship between a number of risk factors and the size of the yield spread of corporate bonds issued by Nordic companies during the time period 2013-2018. In order to investigate this thesis’ purpose, a quantitative method and deductive approach has been employed. This thesis is based on previous research which has investigated what different ri
Quantum teleportation is a way to transfer a quantum state between two locations, by utilizing a shared entangled state, measurements and the ability to communicate measurement outcomes between the two locations. This thesis consists of a theoretical investigation of an experiment that would implement quantum teleportation using single-electron states in mesoscopic architectures. First, we studied
Society intends to become more sustainable and in the work towards becoming more sustainable, circular models have a contributing role in the transition. Combining sustainable consumption with the sharing economy concept could help to tackle challenges such as: the growing amount of waste and climate change by reducing the extractions of resources and regenerated materials within the economic syst
Thesis purpose: By investigating how market driving strategy applies to the context of smaller companies we intend to be able to extend the existing knowledge about market orientation and market driving strategy, and provide practitioners with insights on strategic planning and working with brand identity. We hope that this in turn can help more SMEs survive and be long term profitable. Methodol
This work presents the design for a temperature drift-free path imbalanced ber interferometer for long-term laser frequency stabilization using coated bers with different thermal drift. For this purpose, single acrylate, dual acrylate, copper and aluminum coated bers are analyzed theoretically and experimentally regarding the thermal sensitivity of their optical path length. Experimental results w
When using antibody microarrays to diagnose diseases, the process of quality control of the microarray data is an important step. Currently, a part of this process is performed manually by visual inspection. In this master project, we aim to automate the quality control in order to make it reproducible, as well as to find out which properties of the data that have the most to do with its quality.
I den statliga utredningen, Ett snabbare bostadsbyggande, undersöktes hur utnyttjandet av byggrätter kunde effektiviseras. Underlaget var dock tämligen begränsat, vilket skapade idén till den här rapporten. I vilken utsträckning förekommer outnyttjade byggrätter och varför utnyttjas de isåfall inte? Syftet med denna rapport är att utreda om det finns outnyttjade byggrätter med ändamål flerbostadsIn the public report, Ett snabbare bostadsbyggande, a research was made to find out how the utilization of undeveloped building rights could be made more efficient. However, the material on which the research was based was found insufficient, which created the idea for this report. To what extent do undeveloped building rights occur and what are the reasons? The purpose of this report is to exami

The purpose of this essay is to understand the way yoga is practiced in Sweden through postcolonial feminist theory. The ambivalence of the form yoga takes in a swedish context between the positive aspects it provides for many practitioners in relation to the colonial history and the commodification of the practice is examined through the theoretical and political debate regarding the word cultura
This paper aims to investigate the development of social trust over time globally, as well as separately for continents and countries. This is done by using data from six different surveys and through an interpolation method making the survey measures comparable, resulting in a long and continuous data set. Consequently, with Gini measures from the new Standardized World Income Inequality Database
Syftet med studien är att undersöka om det finns något signifikant samband mellan den verkställande direktören och företagets prestation efter börsnotering. Författarna hoppas studien kan bidra med ny kunskap och inspirera för framtida studier på området. Datan består av 777 företags noteringar på de nordiska handelsmarknaderna Nasdaq Stockholm, Nasdaq Copenhagen, Nasdaq Helsinki, Oslo Børs, First
A sample of 107 asset sales completed globally from October 2006 to January 2019 has been investigated to find the average discount at which the assets of distressed energy companies are liquidated. In the next step, the difference in difference approach has been used to explore the oil price crash in the fourth quarter of 2014 so as to find the difference in the average discount on the assets of
Clustering of orbital characteristics for distant Solar System objects has been proposed to indicate the presence of a ninth planet. Simulations show that the planets orbit would have to have a mass of 5–10 Solar masses, a semi-major axis of 400–800 AU, an eccentricity of 0.2–0.5 and an inclination of 15–25°. Simulations of a planet scattering off a giant planet into a highly eccentric orbit, show
An ensemble Green's function theory for many-electron systems with degenerate ground states, based on the von Neumann density matrix formalism, is proposed. The formalism is constructed without an assumption of an adiabatic connection. An ensemble analogue of Hedin's equations and the GW Approximation (GWA) is constructed. The formalism is applied to four model systems within GWA: a three-
This thesis examines Citizen Participation in Local Economic Development (LED) in Ntungamo District of Uganda. The LED approach is increasingly becoming an alternative strategy that aims at achieving the local dimension in the development process. LED identifies with local resource mobilization, allocation and use. As governments adopt the Private sector led development strategy, Public Private Pa
