Utredning av solenergi för drivning av sorptiv kylprocess för inomhusluften på Stockholmsarenan
Cooling down the indoor air can be done in several ways. One way is desiccantcooling which will be used at the Stockholm Arena. This method is used in airhandling units that use temperature changes and moisture fluctuations in the air. Oneof the steps is to add heat during the cooling process in order to reduce the relativehumidity of the exhaust air. The air passes thru an adsorptions rotor which thenabsorbs moisture from the supply air.

Portning och utökning av processor för ASIC och FPGA
In this master thesis, the possibilities of customizing a low-cost microprocessor with the purpose of replacing an existing microprocessor solution are investigated. A brief survey of suitable processors is carried out wherein a replacement is chosen. The replacement processor is then analyzed and extended with accelerators in order to match set requirements.The result is a port of the processor Lattice Mico32 for the FPGA curcuit Xilinx Virtex-5 which replaces an earlier solution using Xilinx MicroBlaze. To reach the set requirements, accelerators for floating point arithmetics and FIR filtering have been developed. The toolchain for the processor has been modified to support the addition of accelerated floating point arithmetics.A final evaluation of the presented solution shows that it fulfills the set requirements and constitutes a functional replacement for the previous solution..
Forskningsbiblioteket som mötesplats : En ny sida av forskningsbibliotekets uppdrag?
The purpose of this thesis is to investigate how the research library of Linnæus University is used by students as a meeting place. Building upon Putnam's theory of bonding and bridging social capital and Audunson's conception of high and low intensive meeting places, it aims to explore the research library's potential for creating social capital and thus strengthening both learning and democracy in a university context. Borrowing part of the survey design from a study conducted as part of the Norwegian PLACE project, this study collects responses from 134 students as to their use of the library as a meeting place. The results show that the Linnæus University library is used for a variety of meetings of both high and low intensity, why it should provide a good setting for the creation of social capital. There seems to be a connection between how often one visits the library, as well as to which department one belongs, and how one uses the library as a meeting place.
Assessment of food retail business sustainability : the case of Konsum Värmland
Public concern and the need of responsible way of doing business have brought forward the issue of sustainability at the forefront of discussion in the last decade. Even though, food retailers are playing an important role in the economy, they are exposed for criticism by media and consumers for any socially and environmentally irresponsible business practices because, the potential environmental and social impacts from their operations are significant. These impacts need to be recognized and properly addressed. The main objective of this study was to assess the sustainable business management of a cooperative food retail business in Sweden, known as Konsum Värmland (KV). The necessary data and information on history and status of KV, and its practical activities concerning the implementation of sustainable development programs as well as the motivation and challenges encountered by KV during the implementation were gathered via reviewing different documents, research papers and press releases; interviewing decision makers and other personnel in KV and other researchers from Swedish University of Agricultural University who have investigated KV.
Ö?kad tillga?nglighet mo?jliggo?r kvarboende : -En analys av tillgänglighetsrenoveringar
The number of elderly in Sweden is increasing due to improved living conditions and better medical care. It is important that society adapts to the increase and begins to work preventively to reduce the costs of the increase. An important aspect is the elderly accommodation, the cost of health care in specific accommodation is almost twice as high as those for ordinary housing. Therefore, it is important that we availability adapt dwelling to allow older people to live in ordinary housing for as long as they wish, instead of moving to assisted living before they need it. If we can fulfil the elder?s needs with home care instead, society can save a lot of money.In this report, three different forms of housing has undergone accessibility increases and been inventoried and analysed.
Lågkonjunkturens påverkan på den svenska konsumentmarknadsföringen
The purpose of this essay is to analyze and understand the effects that a recession can have on a company?s marketing department.

Det ständigt närvarande svenskämnet : Om högstadieelevers attityder till det språk de använder i andra ämnen än svenska
Film is a tool frequently used by teachers, but it is often limited to showing students how historical time periods looked like, or as a way for students to search for historical inaccuracies. The aim of this essay is to study whether it is possible to use two films based on the legend of Robin Hood as a way to teach students how to contextualize gender history. Through the use of film analysis and gender analysis of two different versions of Robin Hood, The adventures of Robin Hood and Robin Hood: Prince of thieves were analyzed. The study has shown that it is indeed possible to use film as a source material for the study of gender history, and that film can tell us a lot about the contemporary view of gender, masculinity and femininity. The didactical analysis concluded that there was no theoretical objection of using film as a source material; however, there are some things that a teacher should be aware of. Although film may be a good way to create a varied study environment and benefit students with reading- and writing disabilities, there is a risk that time-constraints and lack of knowledge of film and its methodology on, behalf of both teachers and students, may make it hard to implement.

Sjukfrånvaro - ett kostsamt problem
The purpose of this essay is to identify the costs of illness in different organizations, and compare the calculated result with the actual result in their annual reports.We collected information thru interviews with the personnel manager in the selected organizations, and used the annual reports to add necessary information.When we applied our model, we found that the selected organizations, in some cases, have a cost of illnes which is up to seven times higher than shown in their annual reports. It?s, in general, the costs that aren?t related to the salary (additional costs), which are much higher than shown.The absence of a model that calculates the costs of illnes can result in wrongful decisions. If a model would be applied in an organization, it should increase the awearness of the actual costs of illnes, which can lead to better decisions througout the whole organization.This report is written in Swedish..
Kodväxling och intersubjektivitet i tolkmedierade domstolsförhandligar
Reaching shared understanding during court hearings is a prerequisite to ensure a fair trial and maintaining legal certainty. Every month between 2,000 and 3,000 court hearings in Sweden make use of interpreters. Interpreter-mediated conversations involve an extra discourse compared to monolingual conversations which increases the risk of misunderstandings.Using methodology of conversation analysis the study explores how bilingualism is expressed during interpreter-mediated court hearings, at which occasions the Spanish-speaking laymen switch to Swedish and what function the codeswitching fulfills. The study identifies patterns in codeswitching and categorizes them into six different types. Furthermore the ideology of monolingualism in court is challenged and the advantages and disadvantages of codeswitching is discussed.The analysis concludes that even though certain types of codeswitching lead to delays in the conversation, the interaction is mostly favored by the Spanish-speaking party understanding some Swedish.

Turbinkretspump system - Kraftvärmeverket i Borås
The Rya power plant in Borås produces district heating, district cooling and electricity. The plant is owned by Borås Energi och Miljö AB and is run by Dalkia Facility Management AB.In order to get the best heat exchange from the district hot water a pair of twin pumps and a turbine circuit pump are used as return pumps. Turbine circuit pumps are used to increase the pressure through the heat exchangers at the power plant. The pumps are in use when the flow is over 2 000 m3 h-1 and during the summer when re-cooling is used to improve the effectivens of the heat boilers.Since the pumps, that are parallel connected, rotating at a fixed rate per minute, the pressure is regulated with regulating valves. This report shows that during the 4,300 hours that the pumps where in use, energy corresponding to 590 MWh was wasted.
