The Swedish energy company Vattenfall is currently the owner of the district heatingsystems in Nyköping and Motala. To be able to also offer cooling solutions tocustomers are becoming more and more important. This report describes the resultsof an investigation of the cooling market in the two cities and the potential needs forcooling today and in the coming 20 years. The total potential for the coming 20 yearsis estimated to be roughly 17 MW for Nyköping and 9 MW for Motala.Two possible district cooling systems for each of the two city centers was modeledand a comparison was made between different cooling techniques namely absorptionand compressor chillers.Absorption chillers driven with district heating during the summer is one way ofincreasing the load in a combined heat and power plant and thereby the possibleelectricity generation. The cost of heat production must be low for absorption chillerto be able to compete as an alternative.

This essay is a survey of thirteen user studies performed in the field of image retrieval. The purpose is to try to distinguish principles that should be kept in mind when wanting to make image databases available for a wide and varied group of users. The essay tries to answer two questions, namely: Are there any results in accordance among the different studies? What in the user studies should be considered when it comes to how content description, interface and functions for searching can be designed when creating systems for image retrieval? Each study is first reviewed on its own, and then a comparative analysis of all the studies is carried out. Derived from the result of this analysis, the conclusion is presented in the form of a row of suggestions to which aspects are to be suitably included in the design of image databases.

With a growing population on earth the amount of end-of-life vehicles (ELVs) and other scrap steel increases. The European Directive 2000/53/CE? requires a minimum of 95 % reuse and recovery and 85 % re-use and recycling no later than 1 January 2015, for end-of life vehicles. This imposes a need for more efficient recycling and recovery. Despite this shredder residue (SR) is commonly land filled.This report investigated the magnetic fines residue generated at Stena Metall shredder facility in Halmstad, Sweden.

The guest harbor on Utö, Utö Gästhamn, is currently using electricity for heating all of the water used in the showers and taps. Because of the large amount of visitors, especially during the summer months, the hot water usage gets very high and that is also the case for the electrical bills. During the year of 2011 the cost of electricity for Utö Gästhamn reached a total of 257 500 kr. Out of these 257 500 kr approximately 142 000 kr, 55 % of the total cost, were because of the water heating.The report is the result of a cooperation with Skärgårdsstiftelsen, the Green Islands-project and Utö Gästhamn where the mutual goal is to dimension a solar energy system, to promote the sustainable development.Initially the different techniques for the solar energy system are researched. The techniques are plane solar collectors, evacuated tube collectors, pool collectors and photovoltaic cells.

The Göta älv-bridge is a welded steelbridge which is located in Gothenburg,it connects the inner city of Gothenburgwith the island Hisingen. Cracks wasdiscovered in the steel in 1999-2000which started an investigation of thebridge to clearify the condition of thebridge. The conclusion was a monitoringsystem based on laser light sent throughan optical fiber.This report describes the bridge, thedamages, the monitoring system and thetraffic on the bridge.Stefan Pup, at Vectura Borlänge was mysupervisor during this work. In myinvestigation the costs of themonitoring system and the costs ofclosing the bridge is compared andevaluated. The biggest investigatingpart is the costs of closing the bridge.The results of my investigations is thatclosing the Göta älv-bridge would cost 1107 300 SEK / day.

In Sweden prostitution is by many considered to be a social problem that primarily affects women. To counteract prostitution is a political priority and as a result the purchase of sexual services is prohibited by law. Since the law that prohibits the purchase of sexual services entered into force it has been continuously debated and widely disputed. The aim of this thesis is to compare the image of prostitution found in the travaux préparatoires of the law with four sex workers? view of the phenomenon.

This report provides a comparison between the products cellular concrete, foam concrete and LECA concrete. The questions to be answered during the work is how the cellular concrete stands up in cost terms to the existing competitors on the market, how the concrete products differ in design work, and in which situations the concrete varieties are preferred to use.Cellular concrete is a variant of ordinary concrete, with the difference that the ballast is exchanged from stone materials to expanded polystyrene beads (EPS). This substitution gives a product with higher insulation values but lower weight than ordinary concrete.The work was carried out by designing a survey which was sent to two hundred randomly chosen companies across Sweden, to see the building industry?s opinion of the product cellular concrete. The survey showed that cellular concrete was equals its competitors in terms of price, while the product was said to be more flexible, quicker and easier to cast.Then some of the companies, who participated in the survey, were interviewed to see more carefully, how the price, the workmanship and the time for casting and dehydration differed between the products.

Background: outsourcing is one of the most obvious and continuous trends that has been able to study during the past ten years and also has had a strong development in the industry. What consequences will follow from an extended outsourcing? Purpose: the study?s overall purpose is to investigate what possibilities and risks that can be connected to an outsourcing decision and how the order of the service will handle the risks. The study will also investigate what management philosophy that will be used and regulate the outsourcing relation and how the company?s strategy will affect the decision and how the process of outsourcing will look like.

En känsla för Gud ? Komparativ teologi enligt Keith Ward och perspektiv på religionsteologi.(A feeling for God ? Comparative Theology according to Keith Ward and perspectives on Theology of Religion)We all have preconceived opinions regarding people, cultures and especially religion and religiousness, and according to one´s own subjective formed opinion, they are surely truthful and moral. But my main concern with this essay must be thought of as a brief and personal mapping of Christian belief and it´s rational status in relation to both basic philosophy and the other great religious traditions. Furthermore, I am anxious to widen the perspectives of that which theoretically can be considered substantially real, and the existential consequences that follows on such a study. In doing so I must make sure that it´s properly anchored in history of both philosophy and religion, and of course ? with the general idea of God.

Since 1995 the musical Kristina från Duvemåla has been performed on many national theatre stages in Sweden and is still obtaining success and fame. It is based on novels by the famous Swedish author Vilhelm Moberg, Utvandrarna (1949), Invandrarna (1952), Nybyggarna (1956) and Sista brevet till Sverige (1959) that revolve around a Swedish family emigrating to the United Stated during the 19th century. This thesis investigates both the novels and the musical adaptation in a comparative way. Theory of adaptation and intermediality is used to analyse differences and similiarities of the stories used in the novels and the musical. It can be assumed that major changes were implemented in the adaptation of the main characters, specifically Kristina.

I have done a case-study about building a new stable for slaughter pigs at a farm close to Kalmar. The farm is able to supply the breeding with cereals and it has enough area to spread the manure on. The most important factors to gain profit, is the cost for building the stable, the price of the feeding-stuff and the growth of the pigs. The discount from the slaughter-house was less important than I thought from the beginning, and it?s a factor that is hard to influence. With the new production of slaughter-pig and cattle that already exist on the farm, the farm will get a well-functioned rotation of crops with lye and autumn rape as interruption-crop.

Background - Swedish trade and industry primarily involves small corporations, including small manufacturing corporations. Currently, most costing models that are used are based on studies accomplished at large corporations. This conveys to the fact that product costing that occurs at small manufacturing corporations is based on all complexities that large corporations bring, which rarely match with small corporations. It occurs that small manufacturing corporations unconsciously rely on incorrect information that has been calculated based on great corporations? product costing.

The purpose of this report is to document the experiments carried out, methods used and results gained during research into how the silicon content of an aluminium alloy affects the coefficient of thermal expansion (CTE).The goal of this paper is to better understand and to find a relation between silicon content and the coefficient of thermal expansion.Experiments were carried out using carefully prepared samples of Al Si alloys (0, 7, 10 and 20% Si content). Using these alloys, the CTE could be measured using a dilatometer.Comparative analysis carried out could map the effects of silicon content on the coefficient of thermal expansion and an equation was created. Using simple graphs and the rule of mixture method, the authors were able to build a simple tool for calculating the CTE of specific aluminum silicon alloys..

In June 2006 the Swedish government decided that the use of energy in buildings should be reduced by 20 percent until 2020, compared to the level of energy used in 1995. To contribute to this goal, the real estate company ?Eskilstuna Kommunfastigheter AB?, set up own goals for their buildings. In 2009, the goal for schools was to have a maximum energy use of 118 kWh/m2year for heating and hot water.The school ?Hållsta skola?, just south of Eskilstuna, exceeds the limit since it used 270 kWh in 2008.

In this comparative study, intelligibility (as measured by SWINT; SwedishIntelligibility Assessment) and self-rated communicative ability (as measuredby SOK; a self-report questionnaire concerning communication) were investigatedin 29 young adults with repaired cleft lip and palate (CLP) and in 50 age-matchedcontrols. The purpose of the study was to investigate if the outcome of these measuresdiffered between groups and/or with regard to sex, and also to identify possiblecorrelations between SOK and SWINT. Results show that young adults withrepaired CLP had a more positive attitude towards their communicative ability thancontrols, as did men with repaired CLP compared to male controls. Intelligibilitydid not differ between the two groups. A correlation between degree of intelligibilityand self-rated communicative ability was found in young adults with repairedCLP.
