The purpose of this master thesis is to present a model that illuminates the important factors when deriving technical information from market Data within a company. For companies to be able to become and stay competitive in the market, product quality is an important factor. Whilst good product quality leads to customer satisfaction and loyalty, lack of quality brings costs in service and replacements. To improve product quality, the developers need information and knowledge about what quality issues affect existing products. Most companies gather Data from market about known issues, but in order eliminate known quality issues in new products; this Data has to be transformed into information and knowledge.

Background: Phonemically balanced word lists are used when obtaining speech recognition scores in noise. These lists are designed for adults, but are still used for children. To properly obtain speech recognition scores in noise for children, normative Data is needed to show what differences there are to be expected between children of different ages. Purpose: The main purpose is to obtain normative Data for children in the ages of 7, 10 and 13 years for speech recognition scores in noise using words and to compare these with each other and with normative Data of adults. A further purpose is to examine if there is any practice- or exhaustion effect to be seen when obtaining speech recognition scores in noise for children in the ages of 7, 10 and 13 years.Material: The participants were ten 7-year-olds, ten 10-year-olds and ten 13-year-olds.

Inom utvecklingen av de flesta typer av datorsystem används datormodeller för att strukturera lagringen och användningen av Data. Likaså finns det flera olika Datamodelleringsmetoder att välja bland för detta ändamål. I samarbete med ett företag har en fallstudie genomförts med syfte att undersöka hur agiliteten i två av dessa metoder påverkar utvecklingen av ett Data Warehouse (DW).  De två Datamodelleringsmetoder som undersökts är Data Vaulting och Hyper Agility och arbetet har fokuserat på att undersöka skillnaderna mellan dessa när det gäller mängden ETL-kod som måste skrivas, funktionaliteten i Datatransformationerna, möjligheten till att uppdatera systemstrukturen samt den totala kostnaden för utvecklingen av DW-lösningen. Inom ramen för fallstudien har en litteraturstudie genomförts och kombinerats med material från sex intervjuer, där respondenterna varit konsulter såväl som företagsrepresentanter.

I am a glassblower and I am a woman. In this project I've been working with alternative representations of the female body, muscles and technology. Mouthblown objects contains traces of body and form representations.I've been using muscle sensors to collect Data from my arms while I blow glass. A special has made 3D-models from the collected Data and I've blown these viritual objects in glass.My work is based around issues like: What happens when I measure my muscles? Am I (and my process) affected by the Data gathering? How can I create alternative representations of the female body? What is the relation between glassblowing, the objects, body and gender?.

The purpose of this study was to examine the routines of performance related pay systems in two Swedish municipal upper secondary schools. A second purpose was to examine what Data was included for evaluation of a co-worker?s performance and how a principal collects Data. The purpose was also to examine a principal and teachers´ view of performance related pay systems and if it was possible to note an agreement. Principals have been interviewed and teachers have answered a questionnaire to fulfil the purposes of this study.The study shows that the municipality had a good routine that included individual discussions with co-workers about their salary and had fixed municipal criteria.

The aim of this paper is to describe how to measure welfare effect of the deregulation and increased competition of the public transport by railway in Sweden. The paper also includes a numerical example of how to measure the welfare effect. In our study we use public Data from SJ regaring quantity and ticket prices for the period 1996 - 2005. We have used equivalent variation, EV, as the method to measure the welfare effect. We demonstrate how to derive the equation to calculate EV by starting with a Marschallian demand function.

Idag väljer många företag och kommuner att placera Data i molnet istället för på en lokal server, detta medför nya problem som tidigare inte varit aktuella. Datainspektionen har påpekat brister i hur två kommuner använder molntjänster för att lagra personlig Data då de ställer sig tveksamma till molnleverantörernas hantering av Data samt insynen till molnleverantörerena. I detta arbete kommer det undersökas hur den svenska personuppgiftslagen fungerar när Data läggs ut i en molntjänst. Resultatet av uppsatsen kommer även visa på de olika säkerhetshoten som finns i molnet och se vad säkerhetsexperter säger för att ta reda på om kommuner och företag är medvetna om och uppmärksammar samma hot. För att ta reda på detta har intervjuer genomförts med en svensk molnleverantör, företag som utvecklar tjänster mot molnet, privatpersoner som nyttjar molnet och experter inom säkerhet från Blekinge Tekniska Högskola, BTH.

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.

Det här examensarbetet undersöker hur en Databaslösning kan utformas för simuleringsbaserad ruttoptimering. Då det finns få relaterade arbeten inom ämnet syftar detta arbete till att undersöka hur en lämplig Databaslösning kan utformas och ge riktlinjer för detta. Databaslösningen innefattar både lagring av Data samt åtkomst och hantering av Data. Då simuleringsbaserad optimering ofta är avancerad innebär detta att en stor och komplex mängd Data måste hanteras. Simulator och optimerare använder denna Data under själva optimeringsprocessen, vilket ställer krav på effektivitet och snabb åtkomst. Arbetet är inriktat på ett praktiskt problem där sophantering av containrar simuleras och optimeras.

Background:Life-cycle costing (LCC) is an investment calculation that takes intoaccount operating costs throughout the investee lifecycle. LCC calculations are mainly usedto evaluate investments that have no revenue side. Attempts to apply the LCC calculations forbuilding-related investments have occurred since the 1980s. Despite the advantages ofusing LCC calculations, use has not passed through in full. The main obstacles have beenidentified as a lack of relevant input Data, and insufficient experience of workingwith LCC calculations.

The goal of this thesis is to analyse whether the method ?Observiaire? is of any use for traffic analysis. The method consists of analysing film material, preferably before and after changes are made to an area, by answering a survey for the users that are observed within the population. The method also opens up for deeper qualitative analyses which are rooted in the quantitative Data collected from the survey-study. In this study we analyse the method by applying it to the case study of the changes made at Götgatan in Stockholm, where a green wave was implemented and the bicycle road widened.

At Flight and Systems test Saab AB, a post-processing software is used to process GPS Data. A new software by the name GrafNav has been purchased and the purpose of this master thesis therefore became, partly to make a judgment regarding GrafNav?s ability to estimate position, velocity and accuracy, partly to if needed improve the estimate and finally find one or several methods to estimate the position and velocity accuracy. The judgment of GrafNav was performed partly by a comparison to the former post-processing software (PNAV) and partly by a comparison to the airplane?s inertial navigation system (INS).

Examensarbetet går ut på att utreda vad verktyg vid volatil-Data-utvinning (Reeve & Shipley, 2006) orsakar för förändringar på ett Datasystem. Volatil-Data är information som försvinner när Datasystemet stängs av och kan vara nödvändig t.ex. när man försöker läsa en krypterad hårddisk, då krypteringsnyckeln (Casey, et al., 2011) kan finnas i (Random Access Memory) RAM-minnet som är volatilt. I IT-brottslighetens barndom utvecklades (Brown, 2009) metoder för att påverkan på ett Datasystem vid ett beslag skulle bli så liten som möjligt. Detta gjordes för att beviset man får från Datasystemet skulle hålla i en rättgång och gick ofta ut på att slå av strömmen på Datasystemet.
