Trafiksimulering är ett användbart verktyg då olika typer av vägar ska studeras. Statens väg och transportforskningsinstitut, VTI, har under de senaste åren utvecklat en ny landsvägssimuleringsmodell, Rural Road Traffic Simulator (RuTSim) (Tapani 2005). För att en simuleringsmodell ska vara användbar måste den ge en god överrensstämmelse mot verkligheten. Syftet med detta examensarbete är därför att utvärdera RuTSim, genom att kalibrera och validera två 2+1-vägar och en vanlig landsväg med mötande trafik. Detta både för en implementerad frifordonsmodell samt befintlig modell med trafikinteraktioner.

The functional connection between the building and the streetscape affects the city and its attractiveness. Stores located in shopping malls with their entrances facing internal walkways, creates segregation between the mall and the streetscape. This segregation implies that the shopping mall loses some of its attractiveness, which may result in a so-called Greyfield mall. The expression Greyfield mall is used for shopping malls that have lost its visitors. Competition from new modern malls and a lack of investments are examples of factors that influence the development of Greyfiled malls.

This Bachelors exam is about young adults and their use of Mobile Social Network System.The use of mobile social media has become more common in today?s society, ranging fromteenagers, the dominating internet users, to the elderly. The traditional purpose of use inmobile phones, the voice communication from one place to another, has in Sweden beendominated by text communication instead. Along with the development of Smartphones andthe mobile interface, the births of mobile social media have increased in the market.Reports have shown that of all the devices with the possibility to connect to social networks,the one kept closest to our bodies is the mobile phone. One of the advantages of using thephone for mobile social media is that you can easily and smoothly update whenever andwherever, within one arm?s reach.

Every year, approximately 700 000 individuals´ visit an emergency ward in Sweden as a result of injuries and to the emergency ward at Umea University hospital (NUS) about 12 000 injured arrive every year. This study is a retrospective cross-sectional study that surveys injuries caused by crashes among 153 pedestrians and 53 bicyclists, who have been injured in a geographically well defined area during the period January to June 2009. The aim of this study is to survey injuries among pedestrians and cyclists and to examine what preventive measures could reduce these injuries in the Umeå municipality. The results show that falls caused by slipper surface are common among both pedestrians (71 %; n = 109) and bicyclists (32 %; n = 17). Almost one third of the pedestrians (34 %; n = 43) were in the age of 65 or older.

Occupational Health Service (OHS) has an important role in society. It is designed to prevent illness and strengthen the health of workers. OHS operations and development are currently being studied at the School of Technology and Health at the Royal Institute of Technology in Sweden. One of the industries studied is the home maker service. During the 2010s were such employees one of the most ill groups in Sweden.This master's thesis in occupational environment development and change management focus on examining the special knowledge an OHS and its clients in one home maker service need to strengthen the workers of the industry and find out how the interaction between OHS and home maker service works and how it could be evolved.A qualitative study was conducted in a Swedish city on the basis of an organizational perspective.

The main topic of this thesis is to evaluate the impact on the usability of web pages when using responsive web design, a concept for developing web pages whose design adapts to the screen size being used. This is done by creating a responsive prototype based on an existing web site. A number of usability tests are conducted on the two versions of the site in order to compare the time to complete the tests and to observe the behaviour of the test participants. The tests are conducted on desktop as well as on mobile devices with varying screen size.The number of test participants was relatively low, and so the quantitative result is not statistically valid. However, the conclusion is that the most effective combination is to use either of the sites on desktop format.

Syftet med denna litteraturöversikt var att skapa en översikt över vad som kan ha betydelse för bärbara elektroniska teknikstöds användning som kompensatorisk åtgärd för vuxna personer med förvärvad hjärnskada. De 24 artiklar som ingick i studien analyserades med metoden innehållsanalys. Inklusionskriterier var artiklar utgivna efter år 2000 och vuxna försökspersoner. Analysen resulterade i fyra kategorier: användningsområden för elektroniska teknikstöd, design och funktion hos de elektroniska teknikstöden, omgivningens betydelse för användande och individuella förutsättningar för användande av elektroniska teknikstöd. Endast en artikel var skriven utifrån ett arbetsterapeutiskt perspektiv.

Swedens membership in the European Union have resulted in an internationalcharacterized labour market. The construction sector is the area who employs mostposted workers among the 7400 employees who monthly enters the market. It?s alsothe sector where a big part of the work-related deaths occurs. The purpose of this studyis therefore to contribute to a greater understanding of the regulation regarding postedworkers, their work environment and the consequences of it.

Background: The Swedish population is aging [1] and malnutrition is a common problem among elderly people [2]. A method called food registration is used to monitor the patients? nutritional intake, with the purpose of reducing the risk of patients deteriorating in nutritional status during hospitalisation. However, the current method is not satisfactory and many food registration lists are incomplete. [3-6] Thus, patients do not receive a qualitative nutritional care since the assessment of the patients? nutritional status is based on incomplete documentation.Purpose: The purpose of this master thesis is to increase the quality in the nutrition monitoring process in the geriatric units B72 and B74 at Karolinska University Hospital in Huddinge, Sweden.

With the purpose of finding the motives behind use, production and reuse of Open Educational Resources (OER), the writer has conducted a qualitative survey. The three main questions in this two years master?s thesis are:? Why do people use others? unmodified OER?? Why do people produce OER?? Why do people alter and reuse OER?The theoretic framework is built around Manuel Castells? network society, with its social and efficiency seeking dimension, along with the Knowledge commons. Some pedagogy is included as well.A web survey was distributed to 796 users of the Connexions OER repository. 95 responses were received.

Today most ice rinks in Sweden use secondary refrigeration systems with a solution of calcium chloride and water as secondary refrigerant. Due to the large amount of energy such a system uses more efficient systems would be desired.An earlier study concluded in the possibilities of using carbon dioxide as secondary refrigerant with copper tubes as the loops in the ice rink. Since then 3 ice rink refrigeration systems has been built with carbon dioxide in copper tubes. Excluding the ones being direct involved in those projects there is still very little knowledge about how these system works. This study has been made primarily with the aim of adding to the knowledge concerning availability and cost and secondary to look at possibilities for improvement.A comparison between systems with carbon dioxide, calcium chloride respective ammonium solved in water has been made by using Decision Matrix.

The aim of this Master?s thesis is to examine the function of the budget as a means of control within an organisation in the public sector. To accomplish this, a case study has been conducted on a certain business unit within Luftfartsverket responsible for providing Air Traffic Control services. The thesis is built on a framework of contemporary theories of budgeting and includes a brief discussion of the weaknesses usually associated with the traditional budget. The conclusion of the study is that the use of budget as a means of financial control within Luftfartsverket is not efficient enough at the moment.

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.
