This thesis investigate how energy efficient measures has spread throughout the data centers in Sweden. These questions are put up against a theoretical use of such concepts such as green IT, technological evolution, large technical systems and knowledge dissemination. These theories are used to answer the questions that are encountered during the study, such as how green IT is approached, how big of a role environmental thinking has had in the evolvement of these new technologies. The study has been conducted in a longitudinal manner, it is an observation of the phenomenon that is data centers over a longer period of time. 23 non structured interviews spanning over 27.5 hours of recorded material have been conducted alongside a study of archived material.

Simuleringar används i många sammanhang för att underlätta förståelsen för händelser och förlopp som annars kan vara svåra att överblicka. Ofta är det mycket data som ska förmedlas till användaren.I de fall visuella representationer av simuleringen ska visas i realtid måste data sållas bort så att en interaktiv bildfrekvens uppnås samtidigt som betydelsefull information inte får försvinna.Vid Totalförsvarets forskningsinstitut, FOI, används simulering och visualisering som ett verktyg för att studera de komplexa duellsituationerna mellan medel och motmedel (telekrigduellen). Ett verktyg har i detta arbete tagits fram för att kunna använda sig av de stora geografiska områden som behövs i simuleringarna.Resultatet av arbetet är en applikation som utifrån geografisk kartdata skapar ett 3D-landskap som lämpar sig för realtidssimulering..

The recent globalization has to some extent reduced the importance of specific cultures and instead creates a focus on the variation these different cultures provide. Under these circumstances the leader must adapt his leadership to face these new circumstances. The organisations today have to face these new leadership challenges which the global expansion brings. This is a prerequisite for organizations if they want to succeed and be more competitive in a more demanding environment.There are still big differences between the business cultures. There are also differences in the companies? home arena, between groups in the society and all the way down on a family level.

Arbetet beskriver ett systemutvecklingsarbete som innehåller kravfångst, analys och design av en data warehouse/business intelligencelösning till Svenska bordtennisförbundet. Svenska bordtennisförbundet/SBTF/ behöver utöka sitt beslutsunderlag för att kunna fatta strategiska beslut. SBTF behöver även få bättre kontroll på sin verksamhet för att kunna sätta, utvärdera och följa upp mål. SBTF önskar lösa detta genom att skapa ett data warehouse till vilket data från de olika systemen laddas för att därefter kunna presenteras för användarna genom business intelligence. I kravspecifikationen framkom att klubbarnas medlemsregister, alla tävlingsspelare, all träningsstatistik och de matcher som spelats i Sverige sedan 2011 var det dataunderlag som skulle ingå i ett data warehouse.

In this masters paper the change that Lidköping public library went through between 1952 and 1959 is described and analysed. The aim is to describe and analyse the reactions that arose at the time that the first professional librarian, Jörgen Elgström, acted to create a modern public library in the town. The issues that are handled are: How did the local politicians and the general public react to the process of change that was started by Jörgen Elgström? What were the consequences for the staff, the premises, lending, child and youth activities? The paper is concentrated around the period 1952-1959 because this is the time when Jörgen Elgström was working in Lidköping. Jörgen Elgström has a central role in the paper.

Vattenfall and Svenska Kraftnät perform start-up tests, where hydropower generators are used to power up the electrical grid in case of a blackout. To monitor the electrical grid, Phasor Measurement Units (PMU) are used. Each PMU is individually equipped with a GPS-receiver to precisely timestamp the data relative to the official time UTC. During the test, it is also of interest to timestamp the measurement signals from individual hydropower generators to later compare with PMU-data, and thus study the power grids impact on the generator. The aim is to work out an appropriate method to make these measurements and to build a data acquisition system, capable of timestamp data relative to UTC, from a generator in one of Vattenfalls hydroelectric power stations. The problem is that the generator is located in an underground station which hampers the reception of GPS-signals and wiring should be avoided if possible. Time synchronization has been solved by using Vattenfalls network, which is synchronized by the network protocol NTP.

Syftet med denna rapport är att undersöka vilka riskfaktorer det sociotekniska systemet bidrar med vid inmatning av producerade data till en specifik databas. Denna undersökning använder STAMP-metoden (Systems Theoretic Accidents Models and Processes) för att finna riskfaktorer i systemet. Metoden utgår från att samla data om systemet genom intervju, observation samt analys av annan dokumentation kring databasen för att sedan applicera STAMP-analys på dessa. Resultaten pekade på ett antal riskfaktorer vid inmatningen av producerade data, dessa kretsade primärt kring problem med existerande säkerhetsåtgärder, avsaknad av träning samt bristande kommunikation. Resultaten ledde till en slutsats om förbättringsåtgärder på dessa punkter.

Bachelor thesis in political science by Malin Bergkvist, autumn 12.Title:Political governance for increased digital inclusion.Subtitle: Aspects of "governance" and "government".Supervisor: Joachim Åström. While digital inclusion is a hot topic in both academia and in policy circles, little research is done when it comes to governance issues. To help filling this gap, this essay asks which mode of governance is dominant in the field of digital inclusion. What aspects of governance "governance" or "government" is the dominant in the field of digital inclusion, and is it possible to see any difference in how the state governance is described by the government and perceived by other actors? To answer this overarching question, two sub queries are formulated and analyzed. First, what aspect of "governance" or "government" dominate when state governance of the area are examined based on how the government describes it? Second, what aspect of "governance" or "government? dominate when state governance are studied based on how the perceived by other actors and stakeholders active in the field.

The purpose of this essay is to analyze the EU discourse in the Swedish media. The questions that the analysis seeks to answer are; what image of EU is portrayed in the Swedish media? To which degree does the EU discourse fulfill media?s ?news values?? And what are the potential effects of the discourse on EU?s reputation? After several demarcations, I chose 8 articles form Sweden?s four largest newspapers to base the analysis on.    The theoretical and methodical structure behind this analysis is the theories and practices of Fairclough?s critical discourse analysis. Added to the theoretical structure are also theories about reputation and theories about news values. The method used in the analysis is a modified version of Fairclough?s three-dimensional model of critical discourse analysis.

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.
