This thesis investigates if a system for small scale electricity production located in anurban environment can be profitable. The work has been divided up into two parts,one extensive literature study and one case study. The purpose of the literature studywas to investigate the area, resulting in a choice of which technology to be studied indepth in a case study.In the case study a system containing small scale wind turbines and photovoltaicsmounted on Gränby Centrums roof was examined. From data containing wind power,wind direction and total irradiation, possible production from a system weresimulated. Three products of each technology were examined in the simulations.From the simulated production an economic analysis was carried out, this toinvestigate if a system is profitable.

Syftet med denna uppsats är att undersöka varför Afrika har haft så dålig tillväxt de senaste sexton åren jämfört med resten av världen. Paneldata från 41 afrikanska länder mellan åren 1989 och 2004 används för att undersöka åtta variablers påverkan på den ekonomiska tillväxten. Variablerna som ska granskas är sparande, humankapital, inflation, inflation i kvadrat, bistånd, öppenhet, jämställdhet och aids. Fokus ligger på aids och jämställdhet, eftersom de inte varit föremål för tidigare empirisk forskning i samma utsträckning som de andra variablerna. Regressioner gjordes dels över ett treårsintervall och dels över ett femårsintervall för att undersöka hur variablerna påverkar tillväxten för olika tidsperioder.

Our thesis focus on how retirees perceive Tv4s news casts of economy news where we focused on five different aspects: What is the relationship between the news cast and the viewer and how does the viewer express their understanding of the news cast and the way it is constructed? What are the viewers attitude towards the news content and how do they find the news cast useful for them personally?We choosed retirees as our target group due to their vulnerable economic position in today?s society and TV as an important medium for them due to the digital divide. The study was performed with twelve qualitative interviews and one group interview where six retirees took part.We discovered a big interest for economic news in the target group. The majority had a sympathetic view of the news cast they saw but they also expressed skepticism toward the economy segment and/or news castings. The majority expressed a lack of trust for the journalists and the experts brought in to share observations and make announcements, and the financial business overall.

The current situation for Swedish grain farmers facing a situation with decreasing profitability makes it necessary for the farmers to find ways of increasing the margins in their grain growing. Decreasing profitabilities along with Lantmännens closing of grain elevators contribute to the necessity for farmers to invest in grain storing and drying at the farm. By investing in capacity for drying and storage of grain on the farm it is possible to recieve a higher price on the grain sold due to the possibility to sell when the price is higher compared to the harvesting season. An investment in grain drying and storage with a relatively low investment cost that recently has appeared on the Swedish market is the grain stir drying system. This study contains a comparison of an investment in a grain stir drying system where the grain is dried and stored in the same silo and a conventional drying and storage system.

In today?s computerized society more and more companies choose to utilize new applications that can ease the way of handling the information. For many of us is imperative that the process as efficient as possible if one takes in consideration the size of savings that this new application can bring.The developer of the evaluated system is SYSteam AB Huskvarna and they are the ones that gave us this assignment. The application that we evaluate is SCM (Secure Connection Manager). It is already used today by big companies such as Telia and Ericsson to search for errors in telephone servers placed all over the country.

The Oresund Region, consisting of the Swedish county of Scania and the Danish islands of Sealand, Lolland, Falster and Bornholm, is widely recognised as a successful example of European cross-border co-operation. The purpose of this region building project is to form a cross-border fully integrated functional region in order to accomplish a high level of economic growth and employment.This thesis argues, by the means of discourse analysis, that the project can be viewed as a kind of post-politics, defined as a politics that under a neoliberal hegemonic consensus strives to manipulate citizens (and to redefine them as consumers and investors) into better economic performance.This manipulation is carried out by extensive discourse production aimed at convincing people that the Oresund Region exists, that it is a successful region, and that the people who inhabit it are also successful. The deliberate vagueness and contradictory character of the Oresund discourse is investigated and explained as a discursive strategy to incorporate as many views and desires as possible..

A possible way to reduce pollution and slow down the process of global warming is to increase the usage of renewable energy sources. One of these renewable energy sources is solar power. With the aid of solar panels and solar cells the energy from the sun can be transformed into both heating and electricity. The requirement to use the sun in this fashion is a suitable surface, for example a big roof, an angle between 40-60 degrees and that the surface should be exposed to the south. Almost every farm meets these requirements.

Undersysselsättning eller ofrivillig deltidsarbetslöshet är vanligt förekommande på arbetsmarknaden i Sverige idag. Liksom deltidsarbete domineras även ofrivillig deltidsarbetslöshet av kvinnor. Men även män är både deltidssysselsatta och ofrivilligt deltidsarbetslösa. Syfte med den här uppsatsen är att undersöka vilka grupper som är ofrivilligt deltidsarbetslösa samt hur fenomenet påverkas av arbetslöshetsersättningen. Data som används i uppsatsen är från Statistiska centralbyråns arbetskraftsundersökningar samt statistik från Arbetsmarknadsverket.

In this thesis, a computer program that in a simple way can calculate the performance of control loops at the refinery Preemraff Lysekil has been created. The computer program has been adapted to the environment at Preemraff Lysekil. Theories for evaluation has been studied in aspect of reliability and of automatic implementation. The evaluation has been carried out from data collected directly from control loops at the refinery and from simulated control loops with implemented errors. Among the studied methods are Harris index and Stattin´s oscillation index.

FYROM has a long tradition of producing wine. Wine production in FYROM is one of the greatest contributors of the agricultural share of their GDP. The aim of the thesis is to see if the wine production in FYROM has a comparative advantage compared to other countries that produce wine and if FYROM is able to sustain the advantage in the future. The countries chosen for comparison are Bulgaria, Croatia, France and Italy. The methods used in the thesis are the Balassa Index and Porter?s Diamond of National Advantage.

This thesis aims to study the effects of the infrastructure project Västlänken in Gothenburg, a rail tunnel to be built through the city center. The study focuses on the community of Haga where one of the three exits will be constructed and also the surrounding urban environment, to see if the project can be sustainable. Sustainable urban development was selected as the theory, and the term "sustainable" is defined in this study using a number of criteria that two scientists developed. The criteria include economic, ecological and social perspectives on how a place or a geographical area can meet today's needs as well as possible needs in the future. The methods used were semi-structured interviews and content analysis of government documents. Interviews were conducted with various institutions in the city, and companies involved in the planning of the project in Gothenburg.

A purchase decision can be seen as a multifaceted context that raises many unanswered questions. Understanding the consumer's evaluation of alternatives is complex and should be studied at a deeper rather than wider scale. There is a problem for retailers to understand how the consumer manages a purchase decision in a retail setting with durables goods that generates a higher effort. The aim is to describe the decision rules used by the consumer and how they are expressed in this context. A better understanding of which ones they use and how they are conveyed will help retailers to create effective marketing solutions that generate positive outcomes as increased profitability and customer satisfaction.

Den här undersökningen handlar om hur flickor respektive pojkar i en årskurs fem använder värderande uttryck i sina narrativa texter. 22 elevtexter, 11 skrivna av flickor och 11 skrivna av pojkar, har analyserats enligt Appraisal framework. Jag har undersökt hur många och vilka typer av värderande uttryck eleverna använder och även hur de har fördelat uttrycken över texterna i förhållande till den narrativa berättelsestrukturen. Resultaten visar att flickorna använder värderande uttryck i större utsträckning än pojkarna. Fördelningen över de olika typerna av värderande uttryck liksom fördelningen av uttrycken över texten är dock ganska likartad för flickorna och pojkarna.This study concerns the use of evaluation in narrative texts written by pupils in fifth grade.

Syftet med denna uppsats är att undersöka vilka effekter reglerna inom tillväxt- och stabilitetspakten skulle ha haft på BNP. Uppsatsen ger även kort historik och en genomgång av lagstiftningen som omgärdar stabilitetspakten. Den regel som undersöks är 3 %-regeln som säger att medlemsländerna inom EMU inte får ha ett budgetunderskott på mer än 3 procent. Uppsatsen utgår från en reducerad AS/AD modell där finanspolitik är en av variablerna som orsakar skift i aggregerad efterfrågan. Den metod som används är en så kallad VAR-modell där två regressioner skattas, en för BNP-gapet och en för årliga inflationsförändringen.

Den här uppsatsen undersöker den dubbla roll som fossila bränslen spelar i ekonomin. Fossil energi är en viktig del av produktionen och påverkar därmed inkomstnivåerna i positiv riktning. Samtidigt ger den upphov till koldioxidutsläpp som kan påverka klimatet och ge upphov till extrema väderfenomen, stigande havsnivåer, ökad migration och konflikt, vilka så småningom kan orsaka stora externa kostnader. Frågeställningen är:? Hur påverkas ekonomin av koldioxidutsläppande fossila bränslen, beroende på om externa miljökostnader inkluderas eller exkluderas ur analysen?För att besvara denna, utvecklas Solowmodellen med naturresurser så att de fossila bränslenas externa kostnader synliggörs i ökande deprecieringstakter.
