Utility Investment Planning using Risk Analysis: A Case Study of Tanzania’s Power Sector

Investments in infrastructure projects in developing countries are often seen as risky by private investors and local capital markets are not fully developed. Consequently, financial resources and guarantees are often to a large extent provided by financial institutions. Financial and economic analysis is important in assessing infrastructure investment proposals in order to assure that they are f

Economic Partnership as a Stabilizing Factor for Shaping Political and Social Cooperation. The case of Evros-Maritza-Meric Euroregion

Cross-border integration between Greece, Turkey and Bulgaria has been recently dominated by traditional perception of political diplomacy that overrides the considerations for economic cooperation. This project suggests that more in-depth case analysis of the Evros-Maritza-Meric Euroregion will elucidate the evolution of this concept. The existence of long-term barriers in the cross-border region

Enstegstätade putsfasader med träregelstomme

Enstegstätning av fasader fick stor uppmärksamhet i Sverige av allmänheten då SP Sveriges Tekniska Forskningsinstitut under våren år 2007 gick ut med information om dess komplikationer. De komplikationer som uppstått gäller främst för enstegstätade väggar som har tunnputs på cellplast med träregelstomme. Med komplikationer menar man vattenläckage genom fasaden. Dessa uppkommer på grund av fel utfö

Initial steps toward MRI-based treatment planning for external radiotherapy

En ofta använd behandlingsmetod mot cancer är strålbehandling. Inför en sådan behandling undersöks patienten ofta med en typ av röntgenundersökning som kallas datortomografi (eng. computed tomomgraphy, CT). Röntgenbilderna visar hur mycket av strålningen som absorberas av kroppen, vilket innebär att man tydligt ser skillnad mellan ben, som absorberar mer av strålningen än vävnad och luft, som strå"Introduction; The aim of this study was to examine the possibilities for MRI-based radiotherapy treatment planning. The work included evaluation of geometric image distortions in MR-images, investigations of how segmentation of bone could be performed from images acquired with the ultra short time of echo (UTE) pulse sequence and assessment of dosimetric differences between treatment plannin

Trademark parody and Freedom of expression – Shall we dance?

The Thesis’ subject, a notion of trademark parodies, by its legal nature simultaneously belongs to two branches of law – an intellectual property law and a human rights law. Thus, it falls under umbrella of ongoing debate about relations between the aforementioned ones. A chosen area of the research – trademark law – narrows viewpoints to the specific perspectives. The question about parody in law

MRI-Based Quantification of Intra-Myocellular Fat Content

Jag har i detta arbete tagit fram en metod för att mäta mängden fett i muskelceller som vare sig kräver vävnadsprover eller nålstick. Metoden ger också en bild av fettfördelningen i vävnaden. Detta kan vara mycket användbart vid utveckling av läkemedel, men också vid diabetes- och fetmaforskning. Muskelceller innehåller ett bränsleförråd i form av en droppe fett. För diabetespatienter och som en b"Introduction Cardiac steatosis, or overstorage of fat in the cardiac muscle cells, is a possible side effect from drugs treating diabetes mellitus. Therefore, a non-invasive means of fat quantification is needed during drug development. The aim of this master thesis is to develop a method to quantify the fraction intra-myocellular fat in the cardiac muscle of rats using magnetic resonance im

Dosimetric and geometric evaluation of MRI as the only imaging modality for the radiotherapy treatment process of localized prostate cancer

Idag finns det många olika sätt att avbilda människokroppens inre. Två av de vanligaste metoderna som används idag är magnetresonans (MR) och datortomografi (CT). MR använder sig av starka magnetfält och radiovågor för att skapa snittbilder av kroppen, medan CT använder sig av röntgenstrålar. Båda kamerorna har sina fördelar och nackdelar. MR ger bättre vävnadskontrast, det vill säga det är lättarIntroduction MRI provides better soft tissue contrast than CT and is an invaluable tool in the radiotherapy treatment process. The gold standard today is image fusion of MRI and CT data where targets and organs-at-risk are delineated on the MRI data and the dose calculation is performed on the CT data. It is appealing to exclude CT from the process in order to reduce cost and time and to eliminate

En situationsstudie av dissipation beräknad i HIRLAM

Detta arbete har syftat till att göra en situationsstudie av dissipation beräknad i HIRLAM, en numerisk prognosmodell, över Danmark och att ge författarna kunskap om fenomenet turbulens. Studien gjordes genom att bearbeta data erhållen från HIRLAM i MATLAB. Den nedersta delen av troposfären där jordytan har en påverkan på atmosfären kallas för gränsskiktet. När vinden blåser i gränsskiktet kommer This case study aimed at analyzing dissipation calculated in HIRLAM, a numerical forecast model, over Denmark and to give the authors more knowledge about the phenomenon of turbulence. The study was done by processing data obtained from HIRLAM in MATLAB. The lowest part of the troposphere where the surface of the earth has an impact on the air is called the planetary boundary layer. When the wind

Investigating Mono- and Quadrupole Gravitational Light Deflection by Jupiter

Gravitational light deflection in the Solar System can be detected by high precision astrometric measurements. We discuss the parametrized post-Newtonian framework and the comparison of metric theories of gravity. At the precision of a few micro-arcseconds, Gaia data will permit tests of the PPN parameters beta and gamma and to distinguish monopole and quadrupole gravitational light deflection. Ac

JAPAN and The TLM MODEL : Adapting The Transitional Labour Market Theory to Japan

Japanese employment structure has been transforming in the face of economic recession, difficulty in work/life balance and ageing society. The diversification in the forms of employment such as increasing non-regular employment has enhanced labor market flexibility in Japan while causing security challenges for most people. This paper intends to bring a new perspective to Japanese context by apply

Manlighet Under Hot: Kommer män att ändra beteende under maskulinitetshot?

Tidigare forskning har visat att när mäns manlighet ifrågasätts genom ett så kallat maskulinitetshot, så kommer de tillfälligt att bete sig mer stereotypt manligt (Vandello, Bosson, Cohen, Burnaford & Weaver, 2008). Detta för att försöka visa inför andra män att de tillhör ingruppen män. I denna studie undersökte vi om maskulinitetshot kommer att få män att bli mer risktagande och mer intresse

Detection limits and quantification of 60Co with gamma camera and handheld gamma detectors in human phantoms

In an emergency situation where radioactive material has been spread to the environment and large groups of people have been internally contaminated there is a need for rapid examination of the activity contents in those persons. The specific purpose of this work is to explore methods for rapid in-vivo determination of 60Co in humans using equipments not dedicated to whole-body counting, in order

Quantitative tissue classication with dual-energy computed tomography for radiation treatment planning evaluation and optimization of a new method

A new method to extract mass density and elemental compositions of tissues from dual-energy computed tomography (DECT) scans is described and investigated. The method decomposes a tissue into proportions of two or three predened base materials and was proposed in 2008 by a research team at Linkoping University. Informations of tissue parameters may be important in radiation treatment planning to c

The potential of support vector machine classification of land use and land cover using seasonality from MODIS satellite data

Då klimatförändringar studeras är det viktigt att ha markanvändningarna och deras förändringar i åtanke. Markanvändningarna är direkt och indirekt relaterat till klimatförändringar såsom exempelvis stigande temperaturer, vilket påskyndar starten av växtsäsongen. Fjärranalysdata ger en bättre bild av storskaliga förändringar i vegetationen än vad som är möjligt att observera från jordytan. VegetatiWith respect to climate change it is necessary to study land use and land cover (LULC) and their changes. LULC are related directly and indirectly to climatic changes such as rising temperatures that trigger earlier onset of vegetation growing seasons (IPCC 2007). Land surface phenology refers to the seasonal patterns of variation in vegetated land surfaces over large areas using satellite data (R

Evils of Law, Ethics of Violence: A Look on the Derogatory Nature of the Right to Freedom of Assembly

Freedom of assembly as one of the basic requirements of a democratic society is enshrined in various international human rights instruments. This right, due to its importance and necessity for a vibrant society, in itself has a direct link to the realization of other human rights; demonstration and assembly is a form of expression, which can be for the manifestation of other human rights. The wide
