I denna rapport behandlas frågor som rör extern validering och datorstöd (CASE) för detta. Rapporten redogör för en undersökning vars syfte är att ta reda på vilka krav som tekniker för extern validering ställer på CASE-verktyg och hur verktygen svarar upp till dessa krav. Olika metoder finns för att skapa ett informationssystem och varje metod har sina beskrivningstekniker som underlag för extern validering.De beskrivningstekniker som föreskrivs i en metod är ofta mycket detaljerade. En metods notationen ställer därför stora krav på CASE-verktyg som uttalar stöd för denna metod.Arbetet som beskrivs i denna rapport identifierar krav på datorstöd utifrån en viss metods beskrivningstekniker samt ytterligare valideringstekniker som beskrivs i litteraturen. Därefter undersöks CASE-verktygs förmåga att svara upp till dessa krav.Själva undersökningen av verktygen genomförs via ett testförfarande där samtliga utvalda verktyg implementerar två olika testfall.Resultatet från genomförandet av tester visar att det existerar stora skillnader mellan verktygens påstådda stöd för en viss metod och vad de faktiskt klarar av.

The aim of this thesis is to examine the customer profitability in a wholesale company. A case study of Eugen Wiberger AB has been conducted. Firstly the authors have examined the current perception of the company regarding their customer profitability and the results of their calculation of the customer profitability. Secondly an Activity-Based Costing analysis has been performed and has been compared to the perception in the case company. The conclusions are that the smaller customers are the least profitable, and in some cases unprofitable, whereas the larger customers are profitable.

Intensivt skogsbruk har medfört stora förändringar i den boreala skogens struktur och sammansättning. Epifytiska gammelskogslavar så som garnlav, Alectoria sarmentosa, tillhör de arter som drabbats hårt av korta omloppstider och ökad fragmentering av skogen då de kräver gamla träd som substrat samt är känsliga för förändringar i mikroklimat. Vi har med en GIS-analys gjort en modellering över hur stor andel lämpligt habitat för garnlav som finns i Vilhelmina kommun samt hur det är fördelat i landskapet. Modellen baserades på en regressionsfunktion med data från Riksskogstaxeringens inventeringar av hänglavar som grund. En utsökning med kNN-data (satellitdata över Sveriges skogsmark) som bas gjordes och en karta över var i landskapet det förelåg hög sannolikhet att påträffa bra habitat för garnlavar producerades.

Scania är en välkänd tillverkare av tunga lastfordon och bussar. De profilerar sig som det presigefyllda valet med hög teknologinivå. För att kunna leda utvecklingen av nya funktioner och motorer måste många tester av alla system i dessa fordon göras. Till detta används provceller speciellt ordnade för specifika lastbilskomponenter och många av dessa komponenter behöver en yttre kylning under drift varför flera av provcellerna har reglerade kylsystem. Vid uppgradering av kylsystem eller nybyggnation av provceller med kylsystem finns en önskan att kunna simulera och göra tester av kylsystemet innan det faktiska kylsystemet finns på plats, för att säkerställa prestandan innan någon investering görs.

This essay is a case study of how two non-profit organizations, in the same line of business work with external communication and new media such as Internet and social media (Facebook and Twitter).Both these organizations are located in different countries and the purpose of the case study is also to find out if the differences in their work methods in communication depend on organizational or cultural differences. The case study was conducted in the organizations Sverige Amerika Centret in Karlstad, Sweden and The Swedish Council of America in Minneapolis, US. A qualitative approach executed through interviews and a qualitative content analysis of the organizations annual report from 2010. The result of the interviews and the document content analysis shows that there are differences in the way these organizations handle their work with external communications and new media. One of the organizations uses new media more actively in their work with communication and through that channel creates a relationship with its external audiences. The theories that has been used for this case study is Organization communication, Intercultural communication, Public Relations and Organization culture. Keywords: external communication, new media, culture and employees..

This study was made to compare construction companies for gardens way to work with up following, with purpose to see if there was an efficient and not resource demanded system which gave much value. To achieve the purpose a case study was made. The delimitation for the case study was only to compare the work with up following on individual project. The delimitation on the companies in the study was from ten to sixty employees. That because to reach companies were it´s not the same person how calculates on tenders and than perform the projects. The study was delimitated to the west side of Skåne. T o be able to compare the companies and to find trends, an interviewguide was made and was used during the interviews with the companies.

The purpose of this paper is to identify and analyze success factors in the integration of students with special needs in regular schools. This will be done through the case study of a nine year old autistic student in a small town public school ? a fairly representative case for the Swedish school system. The data collection methods used in the paper are; three participant observations of the student, and a qualitative interview with two of the student?s teachers.

A high degree of urbanization with growing cities has raised a need of transforming closed landfill sites for giving them new uses. This study aims to investigate how old landfills can be re-used, what has lead to the new uses, and for what and whom the transformed site will be an asset. The method used is a case study of four different landfills in Stockholm county, Sweden. The case study is analyzed in the light of former studies regarding re-use of degraded urban areas, so called brownfields, and in particular studies and reports of landfill re-use. The result indicates that old landfill sites is identified as an area with possible values if transformed properly, in the case study area especially as green structure and recreation areas.

Syftet med denna pilotstudie var att beskriva hur sjuksköterskor som arbetar som Case Managers uppfattar effekterna av denna arbetsmodell avseende medicinsk vård, social situation, missbruk, vård- och omsorgskvalitet samt samordning för patienter med missbruk och samtidig psykisk störning. Metoden var kvantitativ och genomfördes med en webbenkät. Resultatet visade att respondenterna anser att Case Management haft en positiv påverkan på patienternas medicinska vård och sociala situation. Det ledde också till en bättre kontakt med patienten, och förbättrad bedömning av patientens sammansatta situation. Sammantaget framkom en övervägande positiv uppfattning även av vård- och omsorgskvaliteten, samordningen och de arbetsmetoder som använts.

AbstractIn the fall of 2003 a project was started in the Swedish building sector that is called BASTA (the building sectors’ termination of especially harmful substances). The project is operated by the building companies NCC, Skanska, PEAB and JM, the Swedish Building Industry and the Swedish Environmental Institute IVL. The purpose of the project is to create a common environmental assessment system for the entire building industry and with the help of this system phase out the use of especially harmful properties from building products.In a large sense BASTA works like this; On the BASTA web site there is a database, to which a supplier can register the company and the company’s products. Only those products with a substance content that fulfil the demands of the BASTA system, is to be registered. As it is the supplier himself that carries out the registration of the company and the company’s products to the system, the BASTA-organisation annually controls that the companies that are registered in the database, fulfils BASTA’s demands.Since NCC is one of the companies that operates BASTA, BASTA is probably going to be the environmental assessment system that is recommended for the company in the future.

AbstractThis study has two aims:[X] to create an analytical framework consisting of factors that might trigger terrorism[X] to apply the analytical framework on the case of IRA, in order to be able to examinewhich factors that exist behind the appearance of terrorism in the current caseTo reach the first aim the author has studied the theoretical discourse on the complexed issueof terrorism. This has constituted the point of departure for the creation of an own analyticalframework. The purpose of the framework is to bring clearness to why terrorism appears. Theanalytical framework is not only suited for application on the case of IRA, but for applicationon terrorismcases in general. To reach the second aim the framework was applied on the caseof IRA.The aims of this study have been fulfilled through the method of qualitative text analysis.

This report evaluates whether normal approximation or resampling is to prefer for estimating the distribution of the sample mean and functions of the sample mean. The evaluation relies on simulation studies. The observations of the sample are allowed to be differently distributed. In the case of sample means they are also allowed to be dependent.For sample means the two approximations behaves very similar. The most important component whether we have a good or a bad approximation is how good the approximations catch the variance of the true distribution.

Det finns idag ett stort behov av att kunna klassificera stora mängder data på ett effektivt sätt. Prediktiv modellering är ett område inom data mining där prediktioner kan utföras baserat på tidigare erfarenheter. Dessa prediktioner presenteras sedan i en modell. Avvägningen mellan tolkningsbarhet och träffsäkerhet är ett begrepp som beskriver hur träffsäkra modeller ofta är ogenomskinliga, medan genomskinliga modeller ofta har lägre träffsäkerhet. Detta är ett problem eftersom det finns ett behov av modeller som är både träffsäkra och tolkningsbara.I denna studie visas hur man kan gå till väga för att skapa en modell som har en träffsäkerhet i klass med en ogenomskinlig modell, men samtidigt har en högre tolkningsbarhet.

The purpose of this study is to create a method that can be used to produce decisionsupport data for the climate goals of a municipality. The method should be able to demonstrate the potential for reducing energy use and greenhouse gas emissions for measures aimed at the stationary energy system in the municipality. It will be used to make longterm projections of energy use and greenhouse gas emissions in order to be able to demonstrate the ability to reach climate goals. The aim was also to test the method's applicability by using the municipality of Uppsala and the Uppsala climate protocol project in a case study. Uppsala climate protocol is a project consisting of participants from business, government and organizations that voluntarily want to commit to reducing their carbon footprint by reducing their energy use and thus work to achieve the municipality's overall climate goal. Public reporting of energy use and climate impact has been studied in order to examine the nature of indicators and accounting figures that are commonly used in the field and how long-term forecasts are formulated. In connection to this, the type and sources for the kind of data needed was also examined.
