Syftet med denna uppsats är att undersöka huruvida BNP-gap kan förutspåinflationen bättre jämfört med arbetslöshetsgap. Svensk kvartalsdata från1993 till och med 2005 har använts. Gapmåtten skapas med två olika metoder,en linjärregression och ett HP-filter. En direkt prognosmodell används föralla prognoser med out of sample metodik. Prognoshorisonterna somanvänds är ett kvartal, fyra kvartal samt åtta kvartal.

A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.

Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.

The thesis has as purpose to describe and analyse a decision made be the Swedish tax committee in which it was decided that a cooperative economical associations selling price, which was less than the comparable public bonds market price, would be the focus of a withdrawal tax. There are exceptions from a withdrawal tax, that is if the transaction has a business motivation. However the concept, business motivation, is narrowly interpreted both in the preparatory works and in case law, which makes it irrelevant to the situation at hand. A cooperative economical association is a form of association nearest akin to the limited companies. These types of associations have as purpose to increase their owners wealth with the benefit of freedom from personal responsibility.

Syftet med denna studie är att, med hjälp av ett urval tillväxtvariabler, analysera hur det kommer sig att länder rika på naturresurser generellt uppvisar lägre tillväxt än länder som saknar naturtillgångar. Fenomenet brukar benämnas ?the Resource Curse?, eller ?resursfällan? som det här kommer kallas. Utmärkande för denna studie är att jag valt att analysera hur variablen statlig konsumtion interagerar med naturresurstillgången i landet och hur denna interaktion kan leda till att länderna i analysen fastnar i resursfällan..

This report treats whether it is viable to invest in solar heating to heat the therapy pool at Östersunds Rehabcentrum. The rehab center is owned by the county council of Jämtland and is located on Solliden in Östersund city. The solar heating where supposed to be a complement to the district heating that was heating the pool in the current situation. Later, it however showed that this was not the case. The pool is currently being heated by a radiator circuit that is being heated by the district heating.

In the spring of 2014 Sweco Systems AB were commissioned to design a ventilation system for a newly built preschool in Linköping. Terms from the client was that it cost efficiency would cope with the energy demands that are placed on the building. The unit chosen was a cross-flow heat exchanger, and this work is to compare it with two other heat exchangers to see if a more energy and cost efficient could have been chosen. The heat exchangers that was chosen for the comparison was a rotating- and a counterflow heat exchanger. Simulations have been made to the different heat exchangers by the manufacturers.

Uppsatsen är en kvantitativ studie som undersöker vilka faktorer som har kunnat förklara den svenska swapspreaden under tidsperioden 2001-12-31 till 2008-10-31. Resultatet är en linjär regressions modell som påvisar att swapspreaden är kointegrerad med svenska statens upplåningsbehov samt räntespreaden för europeiska kommersiella obligationer. På kort sikt förklaras swapspreaden av bland annat att den är mean reverting kring ett långsiktigt samband med tidigare nämnda variablerna, basis risken, den historiska volatiliteten på aktiemarknaden, bankaktiers utveckling i förhållande till övriga aktiemarknaden samt lutningen på Money Market kurvan..

I denna studie undersöker vi vad som påverkar oljeaktier och oljeservice aktier. Vi har valt ut fem aktier med varierad storlek från varje bransch, på den amerikanska börsen.Vi använde oss av en multipel regressionsanalys för att komma fram till vilket av oljepriset och Dow Jones index som påverkade aktierna mest. Vi analyserade effekterna både på kort och på lång sikt.Studiens resultat visade att på kort sikt påverkade oljepriset och Dow Jones index aktierna ungefär lika mycket, men på lång sikt var det bara oljepriset som hade en inverkan..

This degree project is based on identifying and allocation of costs in a packaging section at Electrolux Distriparts in Torsvik.The purpose of this thesis is to identify the costs that emerge when packaging different articles and show how the costs are allocated. The report also contains improvement suggestions about how the company can use the current computer system more efficient.The methods that have been used in order to approach the problem and the collection of information have mainly been literature study, interviews and observation.The work started with answering the questions; which expenditure cost and direct cost exist in the section, how can they be allocated, if improvement can be done and how the flow of information is supposed to happen.In order to answer the questions we used our former experience and the knowledge we achieved by reading literature, interview relevant persons in the company and observations carried out in the section.Through our studies, we came up with an Excel file, which is the groundwork for a template that can be used by the company in different occasions depending on the situation and need. It is important to remember to modify the template if the presumptions change. In the template, we have identified the different kind of costs that emerge when packaging different articles and we have also allocated the costs. In addition formulas and estimations that are necessary for the cost calculation are presented.The work consisted in making the groundwork for a template.

Solar energy is the one most talked about among energy sources due to its huge potential amongst renewable energy technologies. A greater use of the solar energy may be the solution to today's climate threats. Normally there are two different types of solar technologies, solar cells and solar thermal collectors. Solar cells convert solar energy in to electricity whilst solar thermal collectors convert solar energy into heat, which can be used to heat hot water for households. This goal of this study has been to investigate the possibility of implementing solar energy into the energy system of Kista Galleria, one of Sweden's foremost venues.

At ABB LV Motors in Västerås the shaft is assembled into the rotor with a shrink fit. After athorough investigation of the assembly method, several factors that make the insertion of theshaft more difficult has been discovered. Some affect the assembly directly while others onlyhave an indirect influence. The investigation has shown that the radial play between the shaftsouter radius and the rotors inner radius might be too small which could lead to anunsuccessful assembly. For the larger rotors, the condition is the opposite, and the rotor mightmove compared to the shaft direct after the assembly when the rotor still is warm.

Latent heat storage is a way to store thermal energy when a phase change material undergoes a phase change. The advantage of latent heat storage is the capability to store more energy per mass unit than other heat storage methods. The most commonly used phase change in latent heat storage is the transition between solid and liquid. Phase change materials can be divided into organics, inorganics and eutectics.In the Nordic electricity market the price of electricity is set every hour by Nordpool spot, which leads to price fluctuations because of changes in demand. The main goal of this report is to create a latent heat storage system in a single-family home and investigate the possibility to save money by charging the latent heat storage system when the price of electricity is low, and discharge when the price is high.The thermodynamic model consisted of a ?tube-in-tube? heat exchanger with phase change material in the outer tube and water as the heat transfer fluid in the inner tube.

This paper studies the research foundations created in 1994 from the former wage earners? funds out of a portfolio management point of view. Firstly it describes the seven largest foundations and their different portfolio management structures. Secondly it analyses the performance of these foundations measured as the intercept, Jensen?s a, in a linear regression of the excess returns of a portfolio versus a proxy for the market, as well as the Sharpe-ratio.
