Implementation av FlexRay prototypstack
FlexRay is a new communication protocol which is fast, reliable and flexible and therefore can meet the increasing demands on data communication in the vehicle industry. The protocol is developed by an industrial consortium containing among others BMW, Daimler Chrysler, Motorola and Phillips. Today (May 2009) Hägglunds is using CAN for data transmission in their systems. CAN is getting obsolete and has difficulties in coping with the increasing flow of communication. In this report FlexRay and its communication capacity is studied.
Den moderna kommunikationen : En rapport om instant messaging och hur det används av unga vuxna studenter.
This paper describes the development of a simulation model for the ambulance flow in the Västra Götalands-region of Sweden, and an analysis tool for the output of the simulation model. The aim of the simulation model was to be able to evaluate the outcome from changes in the ambulance operations, such as a reorganization of ambulances or an increase in intensity of the ambulance calls. This evaluation is meant to serve as decision support for the strategic planning of the ambulance operations. The analysis tool was developed to visualize the abundant geographical data produced by the simulation model in a meaningful way. The simulation model was validated against historical data which showed that the dispatch time for the highest prioritized ambulance calls corresponds well with historical data.

Radialtätning till Retarder
This thesis has the overall objective to develop the optimum sealing system between the retarder and transmission. Today, there is a pressure-relief and two radial seals separation between the retarder and transmission. It has been found that carbon residue formation may occur between retarder axle and seal lips with, in some cases, leakage as a result.We have in this thesis tried to explain the phenomenon of carbon residue, how it is formed and why it can be seen just on the seals? A rig test was conducted where we show how friction, speed, transmission temperature and mitigation phases of the retarder affects temperatures in the sealing environment. Factors affecting the coke structure are reported, together with proposals for measures that provide a mitigating seal environment.
Risker vid svensk företagsverksamhet i Estland
All companies face risk in their daily business. Internationalised companies tend to experience higher risk due to for example unfamiliar business environment than companies that act only on the national market. Estonia became independent as late as in 1991 and is therefore a new interesting market for many companies in neighbouring countries like Sweden. Risks that are most apparent for an internationalised company are political risk, currency risk, capital and interest rate risk, business risk and credit risk. Our intention of this study was to find out how Swedish companies acting on the Estonian market faced the different risks when entering the Estonian market and how they value the risks today.
Återförvilda Sverige?: En studie av rewilding som strategi för att bevara kulturlandskapet och gynna biologisk mångfald
Through millennia, humans have shaped the European landscapes. Agriculture, hunting andforestry have influenced virtually every ecosystem on the continent and formed what we todaythink of as the cultural landscape; a mosaic pattern of cropland, fields, pasture and forests. Thepast two centuries, globalization, industrialization and urbanization have come to pose a threatto the existence of these landscapes. European farmlands are now being abandoned at analarming rate, and the associated loss of landscape preservation, biodiversity and ecosystemservices is a concern to the scientific community and public alike.This thesis studies if the implementation of the relatively new conservation strategy rewilding(recreating self-sustaining ecosystems and reintroducing keystone species) can be a part of thesolution to preserve cultural landscapes and biodiversity in Sweden. Through interviewssupplemented with studies of published works, expertise from different fields has beencompiled to provide an overall picture of the capacity of rewildings as conservation method.
Att göra analoga objekt digitala : En kvalitativ studie om digitaliseringsprocessen i ett bibliotek
Contemporary libraries face challenges in transforming their organization to meet the digitalized society. To develop the process of digitization of literature is a natural way for libraries to go when they already have more visitors online than physically. Since the demand for digital material is so sought after, we feel challenged to address the challenges of the Internet as an emerging functional medium for distributing knowledge. These developments will be able to significantly modify the nature of literature as well as the existing system of quality assurance. In this study, we explored and analyzed a digitization project at a research library.
Läkemedel som förebygger och behandlar trombos hos hund och katt
Several diseases increase the risk of thrombosis in dogs and cats, often with a fatal outcome. Currently there are no definite treatment guidelines for the use of thrombolytic and thromboprofylactic agents in veterinary medicine. None of these drugs are approved for dogs and cats in Sweden. Medicines aimed for humans have been used tentatively. This literature study is an investigation of what is currently known about the effects and safety of these pharmacological agents when used for dogs and cats.
Barn-OPACers grafiska gränssnitt : En studie av tre barn-OPACer på webben
Already in the late 1970´s it became clear that the traditional catalogs in libraries were not suited for children, neither their interests nor their way expressing themselves were accounted for. The goal of this thesis is to investigate if and how children?s OPACs (Open public access catalogs) interface design is at present adapted to the presumed audience of children. My method consists of literature studies and an investigation on the graphical interfaces in OPACs for children, according to the five criteria formulated by childrens library consultant Lena Lundgren and IT-consultant Kia Gumbel. The aims are to find out: a) what requirements for children?s OPAC interfaces and their usability are defined in literature and b) what the actual (real) features of the children?s OPAC interfaces are.
Värdering av tillgångar : En branschpraxis för klädbranschen och byggbranschen
The valuation of an asset is one of the most important thing with accounting, though one of the most difficult thing as well. However, in deciding useful service life for an intangible asset and property, plant and equipment, there are quite a margin for the companies, which creates a difference between companies and industries. When computing the value of the inventories there are a few possibilities available for the companies, which also can generate differencesbetween companies and industries. Although these differences can occur, there might be some similarities in the companies? estimates.

?Dubbelt uppdrag blev trippelt?: måluppfyllelse, värdegrund och? marknadsföring! : - En kvalitativ studie av musiklärarens utåtriktade verksamhet
My research interest in the upcoming paper is the increased need for promotion of schools. I. e. the individual school´s needs to be able to show its existence, in the huge flow and availability of information; schools and universities, study circles, streamed lectures on the Internet, public schools and private schools, different educational directions, et cetera. The schools? needs to market itself, make good PR and sell their pedagogical idea, and that has become increasingly important. My purpose is to clarify how music teachers, in the Swedish primary and secondary school, skills and competences are used in outreach activities within but also outside, the school premises.
