Analys av hur byggnadens höjd påverkar energiförbrukningen i flerbostads- och kontorshus

This diploma work has been carried out in collaboration with the building contractor Sh Bygg Fastighetsutveckling AB in Uppsala with the intention to investigate how the height of a building affects various energy aspects such as transmission losses, infiltration, and the specific energy usage. Three different reference objects have been studied. The reference objects have been simulated for four different heights in the calculation program VIP-Energy.The results show that an increase in floor number can lead to both advantages and disadvantages. As the number of floors increases, transmission losses per square meter floor area decreases. However, as the height of the building increases, the reduction rate decreases.

International transmission of stock market movements - a Scandinavian focus -

Previous research has found an increased transmission of stock movements in Europe, partly caused by the establishment of institutions as the EU and the EMU. The purpose of this paper is to find the possible impact from the EU and the EMU concerning the evolution of international transmission of stock market movements, on four Scandinavian markets, Denmark, Finland, Norway and Sweden. The research is based on primary data, existing theories and earlier studies regarding international transmission of stock market movements. The examined method is a VAR (Vector autoregressive model) including a 10x1 vector of variables. Furthermore the tests considered are correlation, granger-causality, variance decomposition and impulse response.

Effekten av Valutarisk på Bilateral Handel

 This paper evaluates the effect of exchange rate risk on the sum of bilateral trade. To distinguish the effect between different types of countries, two groups are defined: advanced and developing economies. Economic theory on exchange rate risk and trade proposes ambiguous effects of increased volatility. However, the ex ante hypothesis is that developing economies are more sensitive to volatility. Contrarily to the hypothesis, the empirical results suggest that advanced economies would benefit up to twice as much from a removal of exchange rate risk.

Stabil växelkurs och låg inflation - Inbördes oförenliga? En studie av implikationerna av en real appreciering

This paper examines a long run macroeconomic dilemma. This dilemma states that given a real appreciation, i.e. a continuous increase in the real exchange rate, an economy has two options open with respect to inflation and nominal exchange rate. Either the economy chooses a fixed exchange rate- regime but has to allow for a rising inflation. Or the economy can choose an inflation targeting- regime, but then has to allow for an appreciating nominal exchange rate.

Ärligt talat så har jag det som krävs för att vara en bra förälder! : En studie om hur föräldrars generella hälsotillstånd påverkar den upplevda föräldrakompetensen

Background: Good health at community and individual levels are key policy priorities. These priorities can be shown through supporting parents about various different healthy lifestyle choices. In order to know where interventions are needed, it is of interest to study how parents generally feel and how they perceive their parenting.Aim: To study how parents rate their own health and parenting skills, and examine whether there is any correlation between perceived general health and perceived parental competence.  Further, this study will show whether there is a correlation between rate of perceived general health and rate of perceived parental competence when it comes to gender.Method: 64 questionnaires were collected at strategic open kindergartens in the municipality of Uppsala. The questionnaires were distributed to the parents present and who chose to participate in this study.Main result: The result of this study shows that parents have a high rate of general health.

Interest rate and exchange rate impact on U.K. firms

The purpose of this paper is to apply the Dual-Effect hypothesis in Pritmani, Shome and Singal paper (2003), in order to analyze the exchange rate exposure on firms listed on the U.K. market. The study will examine if the foreign involvement of the firm will affect the share price of the firm.In addition to evaluating the Dual-Effect hypothesis in Pritmani et. al. (2003), we will evaluate the effect of foreign interest rates impact on U.K.

Verktyg för mätning av tjänstekvalitet på bredbandsnät

Operators and Internet service providers invest in broadband to be able to deliver new services that require higher data transmission rate. A way to make this possible is to use ADSL, Asymmetric Digital Subscriber Line, as the access technology. To be able to handle this technology, the service providers should do a pre-qualification. Methods and tools are needed to analyze the local copper lines and decide if these qualify for ADSL with respect to service availability and possible bandwidth through the lines. This report brings up some methods for pre-qualification of ADSL, the important quality parameters and how to gather them from the available services today.

STRATEGISK KOMMUNIKATION OCH KOMMUNIKATION AV STRATEGIER : en intervjustudie kring en organisations kommunikation gällande strategier och mål

Purpose: Corporate communication strategies have a central role in disseminating and creating meaning to the organizations? visions, strategies and goals. But many employees do not know the organization?s overall strategies and goals, nor how well the organization achieves these. The aim of this study was to investigate and describe perceptions about internal communication, primarily focusing on communication about strategies and goals.

Implementering av realtidsvideolänk med MPEG- och wavelet-teknik

At Saab Aerosystems, situated in Linköping Sweden, there is a presentation and manoeuvre simulator simulating the fighter jet JAS-39 Gripen. This flight simulator is called PMSIM. In this thesis we study how to transfer sensor images generated by PMSIM to other simulators or desktop computers. The transmission is band-limited so some kind of image coding must be used. Because of this the greater part of this thesis is concerned with image coding.

Varför vill ingen utmana Teracom och Boxer? : En fallstudie av den svenska marknaden för överföring av marksänd digital-tv

The case study we conducted describes market for transmission of terrestrial digital TV. The purpose of this study is to find out what hinders potential entrants from entering the market as well as to discuss possible competitive strategies for potential entrants. Our conclusion is that even though the market for transmission of terrestrial digital TV can be viewed as attractive due to its fast growth, there are barriers to entry that block companies we identified as potential entrants from entering the market. The industry experience of the current market players (Teracom and Boxer) along with their knowledge of the consumers and the fact that Teracom is a multi-business company are some of the factors to be taken into consideration. Switching costs is the most important barrier to entry for the industry.

IDAG OCH IMORGON - En studie av internkommunikationen i en organisation : / TODAY AND TOMORROW - A study of the internal communication in an organization.

A central question is what view of communication is dominating in a municipality in the southern part of Sweden. The study deals with communication theory from two different perspectives; the view of transmission and the view of creation of meaning. Falkheimer and Heide (2003) claim that the view of transmission is one-way communication where the receivers apprehend passivly. In the view of creation of meaning the goal is to develop and strengthen the common notion that exists in a group. Empirical studies were done, that consisted of qualitative interviews with politicians, directors of the municipality, and principals from three childcare and school areas, and also from one upper secondary school.

Hellre överkvalificerad än undersysselsatt - om övergångsfrekvensen till högre utbildning i Sverige under 80 år

This essay aims to explain the fluctuations in the Swedish transition rate to higher education between 1923 and 2002. With theories of human capital, and screening, as points of departure, seven variables are selected and their correlation with the transition rate investigated by use of graphs and tables. The variables are unemployment, youth unemployment, the supply of academics, cohort size, number of high school graduates from programs preparing for ensuing studies, relative wage trends for worker categories with differing levels of education, and structural phase. Results show that no single variable nor the theories of human capital or screening can explain the fluctuations in transition rate in full. Instead I propose a theoretic model which amalgamates the above and places risk aversion as the driving force behind the individual?s educational decision.

Vad påverkar HIV i Sydafrika? : En teoretisk och empirisk analys av Sydafrikas provinser 2008

What affects Hiv in South Africa's different provinces? This thesis examines if education, unemployment rate, GDP per capita, and the literacy rate has any relationship with the Hiv prevalence. This is analyzed using theory and data in the form of a simple microeconomic model and an econometric regression analysis based on cross sectional data of the provinces of South Africa. The regression analysis shows that unemployment rate and education have significant effects of the Hiv prevalence in South Africa. The microeconomic model in the thesis indicates that when education is higher, individuals are more aware that the probability of being infected by Hiv is higher when the Hiv prevalence is high.
