Abstrakt The yield curve as a forecasting tool for inflation has been thoroughly investigated. However, most of these studies considered only the major economies, such as the U.S. economy or the major European economies and not a small open economy such as the Swedish. The Swedish economy should be much more affected by the world economy then the bigger economies. The purpose with this study is then to investigate whether the Swedish yield curve, or the Swedish interest rate, can be used as forecasting tools for the Swedish inflation.

I denna uppsats skapar vi en modell för forwardkurvan på den nordiska elmarknaden. Vårt mål är attskapa en modell som är lättanvänd och inte kräver kunskaper om dynamiken hos elpriset. Vår modellär baserad på en modell av Benth, Koekebakker & Ollmar (2007) men justeras med avseende på vårakrav om en lättanvänd modell. Vi validerar vår modell och nner att den har möjlighet att föutspåpriset på ett kvartlaskontrakt med en felmarginal på 1.1 procent. Vi lyckas förutspå en säsongsvariationutan att specikt ange en funktion för säsongsvariationen..

I detta examensarbete utvärderas väggreppsmätaren RT3 Curve som tillverkas av Halliday Technologies Inc. RT3 Curve kan liknas vid en liten släpvagn som kopplas bakom en bil. Den mäter friktionen mellan två ytor genom två mätdäck som är monterade med fasta slipvinklar. Den fordonsdynamiska termen slipvinkel är vinkeln mellan ett rullande hjuls färdriktning och den riktning som hjulet pekar i. Detta gör att sidkrafter uppstår när släpvagnen dras bakom bilen.

Our examination project has been to develop today?s existing walking frames and make them more exiting and user friendly for tomorrow?s users.The use of a walking frame today makes it easier for a person with a movement difficulty in different extent. It makes it easier with their living condition and the user get a more movement easier life where they can take care of the daily chores without any help from the society or the family members.With our product we get a product that not only makes it easier for the user to get out and get forward. We help the user to get forward where they often would have difficulties to get forward. An example is where its more steeper parts where it could be more difficult to get up or down and even with more difficult foundation due to bad weather.

According to the theory of environmental Kuznets curve there is a relationship between carbon emissions and GDP. The relationship has an inverted U-shape. Carbon emissions rise initially and then decreases once a certain level of GDP is obtained.This essay interprets earlier studies in the field of environmental economics and uses public choice to seek answer on how the population acts on aggregate level. This essay analyses 115 countries in cross-sectional data. The analysis shows that there is a significant relationship between carbon dioxide emissions and GDP that is increasing at first and then decreases for a certain level of GDP.

The market risk premium is one of the most important parameters in finance. Its value and the ways to calculate a risk premium for the market is a widely debated subject. This thesis examines numerous ways of calculating a risk premium for the Swedish market with regard to how good an estimation they make of a real risk premium. Estimations based on historical periods ranging from 20 to 85 years is calculated as well as a premium based on forward-looking estimates. The real risk premium is solved out for a selection of companies and an index with the help of CAPM.

Today automatic milking systems (AMS) are growing in popularity. In these systems the cows are loose and have to get to the robot and the feed on their own. The cows ranking in this system affect their welfare. In this study data from seven years in an AMS was used and analysed. The aim was to investigate how ranking could affect the behaviour of the cows at milking and at feeding.

A study of how pseudoscience is used in modern science as a method for dividing people into groups depending on their extraction with focus on the book The Bell Curve written by Charles Murray and Richard J. Herrstein..

In this thesis a possible cost effective runner change of some of the units in the hydroelectric power station Olidan is investigated. The possibility to drive a unit at the same efficiency point through a change of the turbine shaft speed and the rate of discharge is tested. Furthermore the theories behind model testing, determination of efficiency increase from model to prototype and efficiency measurements shall be discussed and analyzed with Olidan as a starting point.A predicted curve has been built on information from model tests and field measurements on the existing runners and runner data from the test of the new model. The predicted curve shows the difference in efficiency between an existing runner and a modern one. It is the difference in efficiency that is used in the calculations that are to show whether changing to a pair of new runners will be cost effective or not.

SVT is Sweden?s largest TV-network and broadcasts more then 22 000 hours of TV each year. SVT is a public service company where the basic idea is to reflect the world from different perspectives and news is very important for providing neutral and versatile information in a variety of areas. An important part of the flow of information is to continuously receive reports from all corners of the world around the clock. This places very high demands on the technology used and it is important that it function and develops to meet current and future growing needs.

This thesis examines a possible control strategy to minimize flow fluctuations in Uppsala?s district heating system. High variations in flow rate may lead to complications caused by hydraulic constraints in the district heating system. These complications, such as inadequate pressure and temperature levels, increase the risk of heat delivery failures. It is therefore important to avoid such situations both for the producer and for the customers.Typically, the forward temperature is controlled by using a rough correlation with respect to the outdoor temperature.

In conventional viscose manufacturing, a large amount of carbondisulfide is consumed. This amount has to be decreased to keep the production cost down and to reduce the environmental impact. The purpose with this work was to show if an enzyme treatment of a dissolving pulp could increase the degree of substitution in the viscose so that the amount of carbon disulfide consumed in the process could be decreased. Previous investigations by Kvarnlöf (2007), Engström et.al. (2006) and Henriksson et.al.

The relationship between free trade and the environment is often considered conflicting and the debates surrounding it are infected. My thesis deal with this conflict and how environmental concerns are integrated in three regional free trade agreements, North American Free Trade Agreement, The common market of the southern cone (MERCOSUR) and Southern African Development Community (SADC). I point out how the organizations differ from each other in this respect and I present a possible explanation to why they differ. The explanation is founded on the theory of the environmental Kuznets curve and that environmental concerns will depend on which level of development the member states in the organizations have. To judge and rank the organizations I have composed a model based on a pre-existing description of the trade and environment conflict.

The acoustics in a control room is a complicated phenomenon. Early reflections, reverberation time and area in the room are some of the problems. This report is about the reflection on the mixing console in a control room. The control room being built, these reflections are difficult to take into consideration since the mixing console is one of the very last items you place in the room. This report will explain three main measurements that were done in order to get the answer to the following question: Does the mixing console interfere the frequency curve at listening position? Three measurements were done and the difference between the measurements was that the microphone and the loudspeakers were placed in different places in the control room.

This master thesis work was done by two students at Machine Design at KTH for Lesjöfors Stockholmsfjäder AB. The task was to develop a calculation program for gas springs. The program is going to ease the selection of gas springs for a given case of a lid that should be opened. The program is going to be used internal by sales people at Lesjöfors AB in Sweden and internationally. The program is therefore written in English.The program was developed in Microsoft Visual C# 2008 Express Edition.
