One of the city of Stockholm?s main objectives is to have a society completely free from fossil fuels. To achieve this, several investments regarding improvements in energy efficiency and renewable energy are currently being planned or implemented. One of these investments is a project called Hallbara Jarva which is located in the suburbs of Stockholm. The purpose of this thesis is to examine the prospects of an investment in photovoltaic cells from an energy-saving and economical point of view. The analysis is limited to three buildings within Hallbara Jarva and is intended for the property owner.  Solar energy is a type of renewable energy source and is commonly divided into solar heating and solar power.

This is a qualitative study aiming to examine peoples? experiences when retiring. In that purpose a criteria based sample has been used, participants have been asked in that they fulfilled the criteria?s to be a retiree within the age of 65 to 71 years of age. The reason of the age criteria was that the experiences should not be so far away in time.

This case study aims to find out whether the promotion of Swedish news through push technology, and the selection process behind it, obeys the traditional criteria of news values.A months-worth of push notifications, sent out by the mobile phone applications of newspapers Dagens Nyheter and Expressen, were analysed through the application of a number of taxonomies meant to determine their newsworthiness.These taxonomies were, however, based on 20th century media, and do not necessarily adapt well to analysis of digital news publication forms. The purpose of this study is therefore to find out which criteria are still relevant to the news selection behind a digitalformat such as push notifications; and which have become obsolete.The basis of this study is the criteria of news values originally designed by Galtung and Ruge in 1965 and revised by Harcup and O?Neill in 2001; as well as the model of assessing front page news proposed by Hvitfelt. The content analysis was conducted in a manner as similar to that of Harcup and O?Neill?s own study as possible, so as to constitute a re-revisal ?revamped for the digital age.Our results show that the criterion of ?frequency? ? that is the conformance between the time-span of an event and the publication frequency of a medium ? has acquired an ambiguous importance.

As organizations are generating more business intelligence in their systems, more employees need access those systems. As a result some sort of permission management needs to be implemented to ensure the information remain safe. Access Control Matrix (ACM) is one way of managing permissions and is widely used among organizations. The issues that comes with ACM is that the matrix itself gets difficult to manage and overview as its complexity increases with the number of permissions. The study utilizes Action Design Research to develop a tool for visualizing permissions.

This is the end report of my final exam at Medieteknik. It covers the planning, work process and review of a Flash based web application that I set out to do. The goal was to create a user friendly, interactive e-shop with embedded functionality for playing music, displaying rich media content and researching possible payment solutions, to enable buying music files online. The project involved creating the user interface, the programmatic functionality of a Flash client (an SWF file). Also, setting up an Apache HTTP Server and establishing a working ?bridge? between the Flash client and the web server with Flash Remoting components and AMFPHP.

The Swedish model for developing the national infrastructure is based on increasing the cooperation between municipalities, government and businesses. The method to establish the infrastructure in Sweden is the geodatastrategin. The effort to implement the geodatastrategin has resulted in an interaction model, Geodatasamverkan. The purpose of this study is to alert municipalities and to investigate the usefulness of their participation in Geodatasamverkan. The study also presents examples of different applications where geodata can be used within a municipality. The report is based on literature reviews, surveys and interviews. Online Surveys were sent to some of Sweden's municipalities to get an overall idea of ??how they make use of geodata and their general attitude towards Geodatasamverkan.

Idag byter många företag ut sina gamla informationssystem mot nya, standardiserade affärssystem. Detta görs för att man ser stora framgångs- och konkurrensfaktorer i att ha ett standardiserat system, att anpassa ett affärssystem mot verksamheten blir dessutom väldigt kostsamt. På Saab Aerosystems införde man under 2006 just ett standardiserat affärssystem, IFS Applications 2004, där man tidigare hade använt sig utav 59 olika system.Syftet med denna uppsats är att undersöka vilka möjligheter och utmaningar man såg på Saab Aerosystems i och med införandet av det nya affärssystemet. Det utfördes en fallstudie där det samlades in empiri från ett antal kvalitativa intervjuer för att kunna jämföras mot den teoretiska referensram och på så sett kunna besvara frågeställningarna; vilka möjligheter uppstod i samband med införandet av det nya affärssystemet? Hur tog dessa tillvara på? Vilka utmaningar uppstod i samband med införandet av det nya affärssystemet? Hur hanterades dessa? Många av utmaningarna respektive möjligheterna kan ses som nära relaterade, i denna studie presenterar vi hur olika aktörer inom verksamheten upplevt dessa, samt hur de relaterar till existerande teori på området.Resultat visar att följande kategorier: förändring, anpassning av och gentemot affärssystemet, strategi, utbildning och hjälpresurser utgjorde stora utmaningar.

This thesis is closely related to the Dynamically Self-Configuring Automotive System(DySCAS) project. DySCAS is a middleware for electronics in an automotive system. Thethesis work has been performed in cooperation with ENEA. Parts of the demonstrationplatform Self configurable High Availability and Policy based platform for Embeddedsystem (SHAPE) developed for the DySCAS project by ENEA have been used in theimplementation phase of this master thesis.The goal of this thesis was to evaluate how the Meteor MW, an offspring of the DySCASmiddleware, should handle QoS and to design a Quality of Service Manager (QoSM) for theMeteor MW that fulfilled hard real-time requirements. The thesis also had the objectiveof analysing and identifying the requirements on such a QoSM from a QoS perspective.Specifically the requirements to guarantee real-time support for applications running onthe MW.

Linux is a growing operating system in embedded systems. Today, Linux is not only in heavy servers but also in cell phones, PDAs, cameras and other devices running on battery power. While current technology is more energy efficient, more and more technologies are implemented into a single unit resulting in an overall increase of power consumption.Low power consumption is an increasingly important feature of a system today. Lower power consumption means lower costs, less environmental impact, and longer life for applications that runs on batteries.This work compiles methods to reduce power consumption of Linux systems. The work includes examining whether the available opportunities are platform-specific or of a more general nature.

Camelids, especially alpacas, have increased in popularity during the last decade, with the result that they are more frequently encountered by field practicing veterinarians and pathologists. Knowledge regarding their health care and their diseases under Swedish conditions is, however, limited. This became clear in a postal survey among Swedish alpaca owners conducted in 2008. To improve knowledge about camelids in Sweden, this study has examined 107 necropsies, including 93 alpacas and 14 camels, conducted at the National Veterinary Institute (SVA) in Uppsala and at Eurofins in Kristianstad and Skara during the period 2001-2013. The study has shown that camelids in Sweden suffer from diseases similar to those previously reported in other countries in Europe and North America.

The financial crisis in the beginning of the 1990´s the financial crisis had a strong impact on the Swedish economy. Some of the main actors in the crisis were the largest banks of Sweden which brought a huge amount of losses on themselves. One of the main reasons for this was that the banks focused on volume increases rather than on credit losses. The credit analysis process is performed differently these days and it is the development of this process that is the focus for the authors.This thesis is about the credit analysis process in the four largest banks of Sweden. The purpose of the thesis is to highlight which factors the banks include in the credit analysis process and in how small and medium size companies are treated in this process.

This report focuses on the upper slit. The upper slit is located between the impeller andthe drive unit. The slit design depends on pump type and application. However it isuncertain why the design varies, The purpose of this report is to clarify why the designvaries and to recommend an improved slit design.A research has been done; information was gathered from interviews, but also fromsearching of databases and studies of drawings, reports and documents. The originalpurpose of the slit was to prevent twining around the driveshaft, and prevent dirt fromentering the cooling system.

This thesis work is made by Torbjörn Johansson on Karlstad University for Uddeholms AB. The assignment in this thesis work was to investigate tough cutting in three different tool steels: Vanadis 4 Extra, Vancron 40 and Sverker 21. The research was to compare the wear of the tool after cutting in each one of the tool steel alloys. The research was also made to see if the tool cutting in Vancron 40 has a better wear than the tool cutting in Vanadis 4 Extra and also compare the results with Sverker 21. All three of these alloys are a part of Uddeholms AB:s range of products, and is used in applications like forming tools and knife tools. Vancron 40 is a powder steel with a very good combination of mechanical properties like ductility, adhesive strength and hardness.

As a part of the fight against the global warming the energy production needs to be more efficient and redirected towards sustainable options. One alternative is cogeneration, which means that electricity and heat is produced in one plant. The purpose with this survey is to examine if there are any commercial available combined heat and power techniques, based on combustion of solid moist biomass, which are suitable to small-scale applications. The technique must be able to produce between 2 and 10 MW thermal and the heat demand is a Swedish district-heating system. When already published reports had been studied, the Organic Rankine Cycle (ORC) was chosen as the most suitable technique.
