The EU has decided that it should be possible for consumers to get information about the origin of the electricity they buy. Therefore, there is a need to examine different systems for electricity disclosure. In this thesis two ways of disclosure have been studied:? Certificate system. A certificate system involves two parallel markets, one for trading electrical energy and one for trading certificates of origin.? Separated Markets.

This paper aims at assessing the relationship between female and male part-time employment and the business cycle in Sweden during the years 1987?2005 using quarterly time-series data and two alternative indicators of the business cycle. It further aims at determining whether the share of women working part-time has changed over time. Key results include that the relationship between the business cycle and female part-time employment is found to be significant and countercyclical. No significant effect is however found for men.

Previous work by researchers as Eugene F. Fama and Kenneth R. French, show that average return on stocks are related to a firms characteristics like size and book-to-market ratio. These kinds of patterns in average return is not explained by The Capital Asset Pricing Model (CAPM), and are therefore seen as anomalies. Fama and French have proposed a three-factor model, which captures patterns observed in U.S average returns associated with size and value.

In the 1940s the Swedish town planning was inspired by the English city development with the concepts of neighbourhood and community planning. In order to promote democratic development and solidarity the ideal would be to create community centers with full service. Community centers are part of the building of the suburbs during the postwar period. The buildings in Sweden from 1940 - and -50s were built with the intentions to be good homes for all regardless of income, class and status. Collective solutions to individual problems were characteristic of the Swedish policy during this time.

Hazel (Corylus avellana L.) is a common feature of meadows and pastures where it can grow in large populations and become very old. Is it possible to use the size of hazel stools for age determination and is it possible to use the size distribution of a population to provide information about how the land has been used? Hazel populations on ground where the lake-water level had been lowered, has been studied to validate an already developed growth model of hazel clones. Different hazel populations, on wooded meadows affected by mowing or grazing or overgrown meadows, were studied to evaluate the method utilizing hazel as land use indicator. The growth model was used to compare the size distributions of hazel populations with historical periods, which has been important for changes in agriculture or demography.

To be able to compete on the market environmental Management System has become an important part of operations work. However, many companies still haven?t implemented an environmental management systems due to lack of time and the high costs. One of the companies with this problem is Falu Bildemontering. Their goal is to accredited according to the ISO 14 001 certificate.

The consociational democracy model in Macedonia, which came out from a warcrisis and a peace agreement from 2001, in addition, putting an end to the violent conflict, actually admits the division of the society along the ethnic lines. Paradoxically, there is an attempt to bridge the ethnic gap with this model. As a result, the consociational democracy model holds solutions that can be abused if somebody misuses its power and desires to disintegrate the country. The future development depends therefore on the moderate attitude of the citizens, and first and foremost, on the political elites and their commitment to the values of democracy and human rights instead of their nationalistic goals. Furthermore, thepresent democratic consolidation in Macedonia is established on the execution of the peace agreement and the improved effectiveness of the institutions.

Generative artificial intelligence (AI) has rapidly gained traction in the education sector, with tools such as ChatGPT often highlighted as potential support in teachers? daily work. At the same time, the technology raises important questions about how its use should be organized and what responsibilities school leaders hold. The aim of this study is to deepen the understanding of how generative AI is implemented in school organizations, focusing on the strategic work of school leaders and how this is experienced by teachers. The study is based on a qualitative study, comprising interviews with 14 school leaders and teachers in a county in western Sweden.

This thesis discusses model based tracking of radar echoes in tanks with liquid content. The errors in the measurements are not always random in these cases, and the interference that occurs when nearby echoes moves in relation to each other makes tracking difficult. The tracking problem can be broken down to four parts; track initiation, track destruction, association of the measured echoes to the tracks and to update the tracks with the associated echoes. The radar measurement is primarily made on the surface. However, additional echoes from the tank floor or other structures and double bounces are normally present.

Forecasting stock market returns is an interesting topic since more and more Swedes enter and invest in this market. Theory implies, however, that such exercises should be impossible. The aim of this thesis is to investigate the possibility to forecast future stock returns by looking at macroeconomic variables? history. The study is limited to the Swedish market as it is based on the OMXS30-index which represents the 30 most exchanged stocks on Stockholms¬börsen, the Swedish stock exchange.

This thesis compares four relevance feedback methods. The Rocchio and Ide dec-hi algorithms for the vector space model and the binary independence model and Okapi BM25 within the probabilistic framework. This is done in a custom-made Information Retrieval system utilizing a collection containing 131 896 LA-Times articles which is part of the TREC ad-hoc collection. The methods are compared on two grounds, using only the relevance information from the 20 highest ranked documents from an initial search and also by using all available relevance information. Although a significant effect of choice of method could be found on the first ground, post-hoc analysis could not determine any statistically significant differences between the methods where Rocchio, Ide dec-hi and Okapi BM25 performed equivalent.

This diploma work has been conducted for the consulting company Ramböll inUppsala, Sweden with the purpose to perform a study with the calculation programFEM Design 9.0 made by Strusoft. The aim has been to find out if it is possible to gainadvantage by utilizing more advanced 3D software for design calculations, instead ofthe traditional methods currently used in construction works.The method of approach has been to model an existing warehouse building with theprogram FEM Design, and then compare the results with those attained with FrameAnalysis and hand calculations. These results are then analyzed. An evaluation is maderegarding to what benefits can be achieved using a more advanced 3D-model.The results of the study show that the differences between the methods are not ofany significance with regard to the design of the steel frame. However in morecomplex materials such as reinforced concrete, the differences become more notable.The conclusions drawn by the authors of this study into FEM Design are that theeducation requirements of the program are higher than for simpler programs, whosepurpose are solving predetermined problems.

The report aims to describe the austenitic stainless steel Sanicro 25 from a thermomechanical point of view. The thermal and mechanical properties of the material make it suitable for use in coal ? and thermal power plants. By the use of Sanicro 25 it would be possible to bring the efficiency of these plants up while bringing the carbon emissions down.A material model is created from material testing and validated through simulation in the finite element software Abaqus. The model that has been derived describes the material behavior during loading and stress relaxation for the first cycle in a thermomechanical fatigue test well.

Abstract Titel: Det svenska konsumtionsbeteendet ? En ekonometrisk analys av den permanenta inkomsthypotesenTopic/course: NEKK01, Bachelor thesisWriters: Ida Hedlund, Anna Persdotter Supervisor: Fredrik NG Andersson Keywords: Permanent income hypothesis, Milton Friedman, Consumption smoothing, Sweden Purpose: The purpose of this thesis is to examine whether the permanent income hypothesis can be applied on the consumption pattern of Sweden during the time period 1950-2006. Method: To do the observation an econometric regression analysis has been made. The variables tested are consumption, real GDP, stock- and real estate market prices. In the model three different time periods have been investigated to facilitate the origin of different patterns.
