About 80 % of all Swedish dairy cows are kept in tie-stalls, but loose housing is increasing, probably because it is more profitable for the farmer. The design of the floors is of cruicial importance to the cows well-being. Traditionally, the most common type of floor in the alleys of a cubicle system still is a slatted manure-draining floor made of concrete. The typical Swedish design has 125-mm slats and 40-mm slots, maximally. With too wide slots, there is an increased risk of injuries to the claws when the cow makes a hasty move.

The aim of this masters thesis is to study the reliability of the URL as the link between a bibliographic record and a web resource. The Swedish catalogue services LIBRIS and NetSök have been evaluated on three different occasions, to study how these services have succeeded in giving access to web resources by using URLs. Because URLs are changeable, we have tried to find out common characteristics of the URLs in broken links. To accomplish this study we have used a quantitative approach and evaluated five percent of the web resources in the catalogues using a random selection. We have also used documentation relevant for our study, among other things to illustrate previous studies of the nature of web resources and alternative solutions to URLs as access points to web resources.

Slumptalsgeneratorer är bland de viktigaste byggblocken inom dagens säkerhetssystem och infrastruktur. Det finns dock en uppsjö av varierande implementeringsmodeller i såväl mjukvara som hårdvara. Att konstruera en slumptalsgenerator som har tillträckligt bra egenskaper för att användas i säkerhetssystem är inte någon trivial uppgift. I denna rapport diskuteras de två huvud metoderna att generera slumptal, dels i mjukvara (PRNG), dels i hårdvara (TRNG). Olika synvinklar och angreppssätt att generera och testa slumptal diskuteras och utvärderas.

The purpose with this essay was to analyse the view of parental leave in the public and private labour market. How does the economical compensation affect the parent's use of parental leave, with focus on the fathers "earmarked" months? Were there any differences in private companies and public organisations? We chose to look at past research and theories about father/men's usage of "60 day parental leave" from a point of gender and equality perspective. In regard to our questions we preformed qualitative, semi structural interviews. We picked people at random to interview at both private companies and public organisations that had or had not extra economical compensations except what the social insurance office paid during parental leave.

The Swedish reindeer husbandry has had economic difficulties for some years. Due to this, and the fact that the reindeer husbandry plays an important role in Sámi culture, the Swedish state has chosen to support the industry. If these grants where to be withdrawn, the reindeer husbandry as well as the Sámi culture would decrease, which would cause welfare losses for the people living in Sweden. The aim of this study was to elicit what the Swedes are willing to pay to maintain the amount of reindeer husbandry and Sámi culture. By using Contingent Valuation and a survey the willingness to pay was estimated.

This Master?s Thesis examines the subject indexing of all Swedish gay fiction published from year 2000 until 2007. This is done from a queer theoretical- and domain analytical perspective. The study is conducted in the catalogue BURKsök created by BTJ which is the largest library media company in Sweden. The purpose of the study is to examine the heterosexual norm in fiction indexing and to study to what extent gay fiction is to be found by subject.

The purpose of this study was to illuminate dentists? work with guarantees. A case study was performed by personal interviews with dentists from both private and public sector. The result showed how dentists work with guarantees and how they motivate their guarantee obligations. We found that service guarantees? shaping and application should be simple and obvious.

Our project is divided into two parts, one production and written report. The main focus was the production part, were we used PHP to create simple solution for handling SMS and MMS with direct communication with the mobile operator server. We communicate with sockets and can handle CIMD2 and MM7 protocol. To get our components easy to use we have created two classes to handle SMS and MMS. To demonstrate our technical platform we created a website were you can create an account.

Background: The value of stock recommendations have been debated for a century andthe debate has escalated since Alfred Cowles (1933) published his research in ?Can StockMarket Forecasters Forecast?? As of late, savings in stocks has increased and the householdsare managing their savings more actively. The consequence of the increased interestin stocks has resulted in a growing market for stock recommendations. Not just financialmedia but daily newspapers have embraced this new found interest, hence stock recom-mendations can be found in almost all large newspapers in Sweden. Furthermore, this phe-nomenon has also lead to intensified research within stock recommendations.

With the prospect of future construction on the Skutskär Pulp Mill property, Stora Enso Fine Paper has initiated an investigation of soil contaminants and a risk assessment of these contaminants. A soil and groundwater investigation has therefore been conducted on an open area of about 16 000 square meters, situated between the current wood room and digester house. To be able to integrate this study into an investigation for the whole industrial property, the study has been carried out as a phase 2 study according to the Swedish Environmental Protection Agency?s Methods of Inventories of Contaminated sites (MIFO).The site investigation has involved soil and groundwater sampling, together with the analysis of heavy metals and organic contaminants. The degree of hazard posed by the contaminants, the level of contamination, the potential for migration of the contaminants, as well as the degree to which protection of human health and the environment is required in the area, have been weighed together for an overall risk assessment of the area with regard to human health and the environment.The investigated area was built up by filling in the coastal waters.

The subject of this study was to research whether or not the effect of job insecurity on self reported health differs between good and bad times in the economic climate. Two different years of a national health survey from the Swedish institute of health (FHI) served as data, with 2007 representing good economic climate and 2009 doing the opposite. Both years consisted of data from a national health survey distributed to 20 000 random individuals in Sweden, where 2007 had 5738 valid cases and 2009 had 10 373. A quantitative method was used to determine the difference, consisting of a three variable cross tabulation with chi2-analysis as well as a model of binary logistic regression for each of the two years.The cross tabulation found a significant difference between the two years, with those reporting job insecurity having less of a chance to report bad health during the year representing bad economic climate. While the logistic regression showed the same tendency, the two years could not be significantly differed from each other in that part of the analyzes.With this in mind, the conclusion from the whole test was that no significant difference could be found between the years regarding the health effect of job insecurity..

This report contains results of our study at CTC in Ljungby. CTC produces heating products such as boilers, heat pumps and additional products to their heating systems.The purpose of the report is to make a proposal how CTC will supply their new production line for heat pumps with materials. The proposal includes a production layout and a scheme for how to place the material in the production storage.The new production line will produce two different products and both of them have several variants. The line will also have a mixed flow, so the products can be produced in a random order. These conditions demand that the production line has great flexibility and that the material to all the variants can be stored in the production storage.With these conditions as input we made a layout proposal to the company.

The purpose of this thesis is to examine how semantic relations in a document collection can be visualized with a Kohonen self-organizing map. It can be seen as a map of the information space which can be used to support information retrieval. The study makes a comparison of the possible differences between a map that is based on morphologically unprocessed text and a map where the text has been lemmatized. The text that is being processed is the definitions of all the existing instances in WordNet of a random selection of indexing terms from the Times-collection. The purpose is to see if morphological processing somehow can show different semantic connections between term instances based on their definitions.

The aim of this master thesis was to create a dynamic model for the processes in a solid fuel boiler of the moving grate type. Another aim with the model was to keep it as simple as possible but still able to catch the dynamics of the processes in the bedplate of the boiler. The creation of the model had its origin from drying and combustion equations used in earlier modeling work of boilers. The represented model has been used to simulate different kinds of disturbances in a boiler and different ways to control the boiler. These tests show that controlling a number of parameters in the bed of the boiler is an effective way to keep the grate stable during disturbances.
