Denna studie är genomförd på uppdrag av Sony Ericsson Mobile Communications med syftet att identifiera faktorer som påverkar effektiviteten i utvecklingsarbetet och förklara dem ur ett effektivitetsperspektiv. Dessutom skall det undersökas hur det är möjligt att bibehålla eller rent utav öka produkternas och processernas kvalitet. Studien är avgränsad till mekanikorganisationen inom företagets FoU-del och hänsyn till finansiella data har ej tagits. Under hösten 2002 genomfördes en omorganisation med syfte att öka kunskapsnivån och förbättra effektiviteten och det är med denna omorganisation i tankarna som studien genomfördes. Under denna period genomförde även författaren sitt examensarbete inom civilingenjörsutbildningen på just en mekaniksektion som produktutvecklare.

Vacuum box leak testing is, because of geometrical problems, not always possible andtherefore an alternate test method with dye penetrant is used. DEKRA Industrial has identifieda need for quality assurance of the method and development of a written procedure withguidelines that lead to more uniform ways of testing.A literature study was done to get a general overview of nondestructive testing (NDT) and tosee how the method is used in different applications. European and American standards werestudied. Analytical and numerical solutions, involving flow simulation, were deemed to berather difficult and beyond the scoop of this project. Thus the problems had to be solved byusing experimental methods.

Web 2.0 is a relatively new concept which has made significant progress on the Internet. More recently, corporations as well have begun to get use of the different types of applications that are assigned to the Web 2.0. Organizations are primarily interested in making use of Web 2.0 in two areas: inside the company to increase efficiency and productivity, and from the organization to the customer to improve revenue and customer satisfaction. We have chosen to take a closer look at this last area, as can be seen as a CRM context. Our interest is to investigate how such a context may change by implementing some kind of Web 2.0 technology.

I dagens hårda konkurrenssituation krävs det mer och mer av företags informations-system. Detta gör att fler och fler företag väljer att implementera ett integrerat affärs-system. Integreringen gör att företag får en enhetlig systemmiljö för hela företagets informationsbehandling. Implementeringen är dock en kostsam och tidskrävande process (Ekstrand, 1998). Mitt arbete behandlar frågeställningarna om varför företag väljer att implementera ett affärssystem, hur implementeringen förlöpte samt hur affärssystemet fungerar när implementeringen är färdig.Bland de företag jag vände mig till så var den främsta anledningen till att företag installerar ett affärssystem att systemen är omfattande och integrerade.Jag kom även till slutsatsen att det nästan är omöjligt att genomföra en implementering av ett affärssystem helt smärtfritt.

Det har blivit allt vanligare att vi idag använder våra mobila enheter till att besöka webben. I detta examensarbete undersöks vilka centrala designprinciper en designer bör eftersträva när avsikten är att förenkla användningen av en webbplats i en statisk och en rörlig situation via den mobila enheten. Examensarbetet innefattar en litteraturgenomgång, observationsintervjuer vid två tillfällen och en prototyputveckling. Det första intervjutillfället identifierade de grundläggande designprinciperna som sedan stod till grund för prototypen. Det andra intervjutillfället genomfördes mot prototypen med samma individer.

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.

As the volumes are entering the world of computer graphics the pure volume visualisation becomes a more important tool in for example research and medical applications. But the advance in haptics --- force feedback from the computer --- is behind. In volume haptics no equal to the proxy method so popular in surface haptics has yet emerged. Some implementations of volume haptics even use surfaces as intermediate representations so that surface haptics can be used.The intention of this work was to create natural feeling haptic feedback from volumetric density data using pure volume haptics. The haptic algorithm would be implemented in Reachin API for the Reachin Desktop Display, together with other parts to build up a usable volume visualisation environment.To achieve the feeling of stiffness and friction dependent on tissue type, a proxy based method was developed.

This study concerns design thinking and how to achieve usability when designing applicationsfor smart watches. The study's focus is on interaction and design for online auctionapplications such as Ebay and Tradera. After studying usability and design for devices withsmall screens, guidelines and design principles for interactive systems, we developed apaperprototype for an auction application. The prototype was used for testing our intervieweeswhile observing and asking questions. After collecting the data we analyzed the responses andfeedback on our prototype and combined the results to previous studies.

This report presents the results of the tests of data rate and signal strength that I have conducted. The tests have been performed in the municipality of Arvidsjaur, Sweden. The report also contains the conclusions I have drawn from the results as well as an introduction to radio and the technology used in the nets that have been testedThe equipment used is:LG G2 cellphone used to test Telias 3GHuawei b593s-22 3G/4G router used to test Tele2s 3G/4GMobile Broadband Gateway R-90 used to test Net1s CDMAThe data rate has been tested with bredbandskollen (www.bredbandskollen.se). The signal strength(RSSI) has been read in the configuration menu of the broadband routers as well as in the cellphone.The conclussions drawn:Net1s net appears to be more used compared to its capacity than the other netsTele2s net has a high and even data rate where it?s signal strength is sufficient.

Företaget Rebtel ville ha en ny landningssida som riktade sig till internationella studenter. Denna sida skulle vara optimerad för målgruppen både gällande design och innehåll. En förundersökningen bestående av bland annat intervjuer med målgruppen, målgruppsanalyser och research gjordes därför. Förundersökningen bestod också av intervjuer med olika roller på företaget Rebtel för att få en inblick i olika arbetsrollers perspektiv och uppgifter under en sådan process. Med hjälp av förundersökningens fynd togs skisser fram och en landningssida utvecklades bland annat genom programmeringsspråken HTML5, CSS3, LESS, JavaScript, .NET och C#.

This report gives an overview of applications of the Greenroads rating system whichin turn is an environmental review system for roads. The focus of this report isapplications during the construction phase, ie on solutions which adhere to theentrepreneur's area of responsibility as opposed to the designer's. The study was undertaken in cooperation with Skanska (a global contractor andFortune 500 company) which provided a project suitable for an exemplatory study ofGreenroads. Please note that the project in particular was not specifically designedwith Greenroads in mind. Therefore and because of that the site provided anexcellent opportunity to study effects of application contra non-application. The approach of this study was to first review the system, thereafter to performinterviews with key personel at the site in different roles as to receive different viewsof selected points of application. Selected possibilities of application are cathegorizedand presented with comments and suggestions for adoption. Lastly Greenroads is briefly compared to the rating system which today is the mostwidely used by Skanska, LEED.

Background: With the removal of audit requirement for companies in Sweden from the first of november 2010, a lot of companies has chosen not to keep the audit requirement. So far 57 percent of the small companies has chosen to keep the audit, in spite of that they don´t need to which led us to the problem statement: Which are the factors that affect a small limited company to choose to keep the audit, in spite that now there is a possibility to choose not to use audit anymore?Purpose: The purpose of the essay is to examine why small limited companies choose to keep the audit, in spite that now there is a possibility to choose not to use audit?Method: This research founds itself in a qualitative study with a deductive research approach. We have been studying secondary data in books and articles and preformed 29 phone interviews with small ltd company owners in Sweden. The selection consisted of 14 companies with credit debts and 15 companies without credit debts.

Introduction: The population of Sweden has during the last century doubled. An increased live expectancy results in an older population and the share needing medical care increases. Demographic and political changes in developed counties have resulted in changed demands on the care of the elderly. The elderly are discharged from hospital earlier and this results a significant responsibility on the elderly themselves and their relatives. Often the relatives are engaged in the elderly?s health problems, care needs and the future consequences the current situation results in for the elderly and the domestic life.

The Swedish concept of bildning, related to the German Bildung, finding its correspondence in English in refinement, formation and culture, is an important, though traditional rather than modern concept in cultural policy and sphere. The concept connected to the activity of the public library is relevant, as the library uses the word as a description of parts of its work. The meaning of the concept can easily be seen to be complex as well as disputed, borders on and is related to other concepts. The paper discusses different meanings to the concept according to different Swedish authors, as well as the connection of the concept to related ones. The varieties and differences are expressed as differences in discourse.

Unhealthiness is not just a damaged back or asbestos. The fact that mental ill-health seems to increase in our society is well known. Statistics from Arbetsmiljöverket proves a fourfold increase of work-related disorders since 1997. These are primarily caused by organizational and social factors, 60% are considered caused by stress and a heavy workload. Sick leave due work related fatigue and depressions are scarily common today.
