Dagens moderna organisationer driver vanligtvis en kostsam IT-baserad infrastruktur. De besitter högpresterande funktionalitet och säkerhet för att garantera att de dagliga operationerna fortskrider. Mjukvarubaserade lagringsplattformar är ett alternativ som kan användas för att reducera dessa kostnader. Genom att efterlikna avancerad teknik som redan existerar i traditionella lagringsplattformar kan detta implementeras som mjukvara på commodity hardware i syfte att uppnå samma funktionalitet. Ceph är ett alternativ som numera implementeras och ämnar erbjuda detta val.

The purpose of the thesis is to investigate whether a higher income make individuals more likely to exceed the speed limit. In addition to income the variables age, sex, perception of the speed of the average driver and offense history for the last three years are taken into account.The method used is based on a survey performed at the mandatory annual motor-vehicle inspection (Bilprovningen). 177 individuals were asked to participate, of these, 124 completed the survey which in turn left us with 117 usable observations.The analysis is based on two forms of regression, a linear regression and an ordered logit regression to confirm the results for the ordinal Data.The final model indicates a result where income and age are statistically significant. Sex is considered insignificant for our Data material and is excluded from the model. Age has a negative effect on the propensity to exceed the speed limit while income has a positive effect.

In all types of learning situations, it is important to find each student where they are at the moment in knowledge. I have reflections about  what animal experience students have with them when they begin their education. This thesis is about what home environment and in home environment acquried animal experience student at agricultural college have. This work is based on Data collected through questionnaire survey done in two agricultural colleges in middle Sweden in the spring of 2007. Questions were divided into four blocks, historical Data such as on the environment in which pupils are growing up, animal habit, why they read on agricultural school and future Data on what plans students have for future education and careers.

Three-dimensional computer graphics enjoys a wide range of applications of which games and movies are only few examples. By incorporating three-dimensional computer graphics in to a simulator the simulator is able to provide the operator with visual feedback during a simulation. Simulators come in many different flavors where flight and radar simulators are two types in which three-dimensional rendering of large terrains constitutes a central component.Ericsson Microwave Systems (EMW) in Skövde is searching for an algorithm that (a) can handle terrain Data that is larger than physical memory and (b) has an adjustable error metric that can be used to reduce terrain detail level if an increase in load on other critical parts of the system is observed. The aim of this paper is to identify and evaluate existing algorithms for terrain rendering in order to find those that meet EMW: s requirements. The objectives are to (i) perform a literature survey over existing algorithms, (ii) implement these algorithms and (iii) develop a test environment in which these algorithms can be evaluated form a performance perspective.The literature survey revealed that the algorithm developed by Lindstrom and Pascucci (2001) is the only algorithm of those examined that succeeded to fulfill the requirements without modifications or extra software.

Denna uppsats behandlar ett beslutsproblem i ett stort högteknologiskt företag, nämligen att prioritera mellan investeringar i utvecklingsprojekt för produkter. Dessa projekt har två mål, att utveckla funktionaliteten eller att minska driftskostnaderna för produkterna. Företaget anser att dessa mål är svåra att uppnå samtidigt och att en ökning av funktionaliteten får till följd att driftskostnaderna stiger. Företaget vill veta den optimala fördelningen av investeringar mellan att utveckla funktionaliteten och att minska driftskostnaderna.En modell utvecklas för att representera dessa fenomen. Prognosticerade värden används i modellen vilket gör business case till ett centralt begrepp, vilket redogörs utförligt för.

This assignment has been performed at location and commissioned by AttenditAB in Jönköping. The task has been to develop a client/server system to accessData stored in SQL Databases where the client application is developed to run onregular cellular telephones. The importance has been to develop as reliable mobilecommunication as possible. The functionality that is demanded upon the mobilecommunication is:? Secured for future versions? Interoperability? Data should not be bugged, modified or disappearunnoticed? Resource efficientWe have achieved these demands by developing our own protocol that is on top ofthe TCP protocol.

The climate changes and the global warming have a great impact on the Arctic environments. This partially depends on that the albedo is getting lower when snow and ice is melting and exposes more and more dark surfaces of the land and sea. This leads to a feedback effect; the melting accelerates because dark surfaces attract more sun radiation. Because of the heating the glaciers in Arctic retreat. The purpose of this report is to obtain an eventual change in elevation on the glacier Lomonosovfonna that is located on Svalbard by comparing elevation Data collected by NASA and GPS Data from 1996-2012.

This project examined the possibility to create an electronical aid with the purpose of increasing environmental awareness and to design the aid in a fashion that inspires other to develop similar applications. The impact of car traffic was examined, and the base of the aid was built up in modular form to simplify the hardware aspect. For the active, Data processing part of the aid the Arduino platform was chosen because of its simplicity and big possibilities of help in different internet fora, for those who choose to create similar applications in the future. The main part of the project var the use of real-time information from the car?s on board diagnostics.

Thesis purpose: The aim of this paper is to extend the knowledge of what influences the purchase decision of functional food in the store. By applying the M-R model in a new setting - the dairy department in grocery retailing in Sweden - and adding variables related to health attitudes, the aim is to contribute to existing research concerning in-store purchase decision making and store environment as well as consumer attitudes. Methodology: This thesis employs a quantitative strategy with a deductive approach and Data has been collected with questionnaires. Theoretical perspective: Environmental psychology serves as an overarching framework where, more specifically, certain aspects of store atmospherics and some variables concomitant to health attitudes provide the theoretical base. Empirical Data: The empirical Data consists of customer purchasing a functional food product, Proviva, and this is contrasted with a test group, Bravo.

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 tourism industry in EU is one of the biggest sectors and employs about20 million people. A key factor of the industry is information, much oftourist information is today on the Internet. On Internet there is twoways information can flow, the information can either be pushed to aconsumer or the consumer of the Information can pull it from a source.In a feasibility study for the report the participants expressed thatthey thought the tourist information on the Internet was unpersonal anddidnt fill their informationneeds. The purpose of the report was to findout how push and pull of touristinformation can be balanced on Internet.The empirical Data was collected with a feasibility study, a survey anda case. The survey was conducted at IT-University and School of Business,Economics and Law at Göteborg.

The management of information is a significant competitiveness in companies. Companies stored and save information every day, and it is very common to save de information in different sources. This makes de management of information complex. To mange, monitor and analyze the information, companies can use a system called Business Intelligence. BI system is an analytical system that extracts and converts Data into useful information that helps employees to make informed decisions.

AbstractThis study is about describing the pre- internationalization phase and to studycompanies that are in this phase. We are trying to capture characteristics of decisionmakersin the pre- internationalization phase, to then compare the theoretical materialwith empirical material from case companies. Then in the final stages of the thesis, wewant to account for if we managed to answer our research questions. In the method, wegive a description of the approach selected in conjunction with the study. The study isqualitative and we used both primary and secondary Data, with a deductive approach.The theory chapter will consider the most relevant theories that are related to the topic,which is internationalization, pre-internationalization, international entrepreneurship,and the psychology behind personalities, attitudes, and how these can affect theorganization's strategic decisions.

Det finns flera olika metoder och tekniker för tredimensionell rendering, alla med olika för- och nackdelar som lämpar sig för olika applikationer. Voxelbaserad rendering har använts flitigt inom vetenskapliga områden, främst inom det medicinska för visualisering av volymetrisk Data. Tekniken används nu inom flera olika områden för tredimensionell rendering, t.ex. i datorspel, i matematiska applikationer och vid geologisk rekonstruktion. I den här rapporten kommer voxelbaserad rendering med Marching Cubes-algoritmen undersökas för att se hur den lämpar sig för realtidsapplikationer.
