Building Automation Systems in commercial buildings are often designed and installed by different contractors, using equipment and components from different manufacturers. The lack of an accepted communication standard has resulted in a few different standards. Many manufacturers of building automation systems only support one, a few or none of these standards, while developing proprietary system solutions. Regin, who develop such equipment, are planning to adopt an open communication protocol specially designed for building automation - BACnet. As a step in that direction this thesis was announced with the purpose to investigate the possibility to implement BACnet in one of their products and to gain more knowledge of the BACnet protocol.

This master thesis project will describe and evaluate the interfaces between applications and Controller Area Network, CAN, interface boards from different manufacturers. The interfaces have corresponding functions but the usage of parameters is different. The simply communication of sending and receiving messages is more alike than the supplementary functions between the different interfaces. The CAN communication is more controlled by the CAN protocol and is therefore more alike. The evaluation shows differences and similarities between different interfaces and also difficulties and options to translate them.

Voice-over-IP (VoIP) är en samling teknologier för transport av digitaliserat tal över IP-nätverk. Den mest kända applikationen för VoIP-teknik är internettelefoni. Processorer och gränssnittskretsar som kan realisera ett VoIP-system har utvärderats för användning i produkter med låga produktionsvolymer spridda över flera år. Komponentkostnad, utvecklingskostnad och även hur länge komponenterna kommer att tillverkas är viktiga faktorer att ta hänsyn till. Resultatet av studien är att generella signalprocessorer av den nya generationen, med arkitekturförbättringar som ger mer microcontrolleregenskaper, är de bästa kandidaterna.

The “peer to peer” (P2P) is a technology of downloading and filesharing between online - Internet - users by the mean of specified software. Since June 1999, the Napster software has made the happiness of millions of individuals who used it to obtain and share free audio files Mp3. Rapidly, the major recording companies have prosecuted the Napster Company and managed to force it to close down. They were arguing against it for it is supporting the development on a large scale traffic of files protected by copyright and thus was threatening the whole music and movies economic world. Since fast Internet connections multiplied, "peer to peer" software and networks improved, so that this mode of exchange became an unprecedented success. Today all cultural products, in particular films and music, are concerned with this free –of– charge distribution without any financial counterpart for the copyright holders. Two tools hold today the top ranks and concentrate large traffic: eDonkey and eMule.

Uppsatsen är en kvalitativ studie med deduktiv ansats. Materialet har samlats in genom semistrukturerade intervjuer och enkäter. Utgångspunkt är teorier om budgeteringens syfte och dess roll i kommuner, olika kommunala budgeteringssystem i allmänhet och behovsbudgetering i synnerhet samt betydelsen av väktar- och förkämperollerna i budgetprocessen.

The aim of this Master of Science Thesis is to develop guidelines and improvementsuggestions of RiNOVA Traffic AB?s dynamic speed bump. The project started with athorough pre study of the design and its function to find out how passing vehiclesaffects the dynamic speed bump. The majority part of the pre study was to createnecessary mathematical models to explain the arisen forces and strains.The results of the mathematical models gave necessary information about the designregarding weaknesses and flaws. The most critical ones where those which interferedwith the design?s performance and reliability, and therefore needed to be corrected.These problems where more thorough analysed and discussed with experts before thefinal guidelines and improvement suggestions where developed.The parts of the design that had to be redesigned were the extension springs and thebearing that enables the dynamic properties.

A new shipyard on the island of Beckholmen consisting of a new ship hall and complementary workshops. The program is extended with rentable industrial space for other smaller companies to take advantage of synergies with the yard and to create an active maritime cluster around Beckholmen. By building a marina and a port at the northern shoreline of the island the shipyard can expand their potential customers to non-commercial and larger recreational boats that are becoming increasingly common in Skärgården. The port is also supplemented with a combined naval fuel station, harbor office and a small café. The boat traffic in the region gets a additional stop at the end of the port and act as an additional gateway to Djurgården. Several small retail spaces with direct access to the water is created along the promenade between the port and Djurgården. The shipyard gets a modern and efficient industry building, while the island is made available to the public again, and Beckholmen will hopefully take an equal place in the city's consciousness as it does visually in the inlet to Stockholm..

The purpose of this essay is to investigate whether the implementation of the Solvency II directive will create a competitive advantage for the Swedish insurance companies compared with other insurance companies in Europe.Therefore the theoretical perspective illustrates the specific requirements and risk culture of the insurance industry and defines the critical success factors for a successful implementation of the directive. The empirical foundation is built on the QIS 5 reports for Sweden and Europe, interviews with the financial services and If insurance company as well as information from a seminar organized by KPMG. The analysis shows that the Swedish insurance companies meets the capital requirements of Solvency II by a large margin and that they are accustomed to risk management and reporting requirements from the traffic light model. This implies that the three critical success factors for a successful implementation of Solvency II are met, although with some limitations, and that Swedish insurance companies could possibly have a competitive advantage.     .

Vi kommer i denna rapport undersöka hur ramverket Derby kan användas inom spelutveckling tillsammans med HTML5 och CSS3. Derby är ett MVC-ramverk som bygger på Node.js. MVC (Model View Controller) är ettdesignmönster som används inom systemutveckling. Designmönstret separerar presentationslagret och datalagret genom att införa en komponent emellan som kallas controllern. Det Derby framförallt tillför till Node.js är synkronisering av data mellan servern och klienten.

We travel more nowadays. The increasing travel rate generates greenhouse gases which in the long run cause an increasing number of natural disasters over the world. Car traffic is a major contributor to this development. Out-of-town shopping centres have historically good accessibility for car traffic. This study aims to look into what are the factors that influence the choice of transport mode for dwellers in the outskirts of a town when going to out-of-town shopping centres.

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.

This master thesis was made to validate hydropower models of a turbine governor,Kaplan turbine and a Francis turbine in the power system simulator ARISTO atSvenska Kraftnät. The validation was made in three steps. The first step was to makesure the models was implement correctly in the simulator. The second was tocompare the simulation results from the Kaplan turbine model to data from a realhydropower plant. The comparison was made to see how the models could generatesimulation result that was similar to the reference power station.

Man?s impact on the environment is something that increasingly becomes topical in today?s society. Because of this, several companies have started to take interest in the effects they?re responsible for, not least considering their image. Emissions of carbon dioxide generated from goods traffic are accountable for a large part of the total emissions of greenhouse gases in the world.

I detta exjobb har en testplattform skapats för att kunna testa, utvärdera och jämföra olika pumpstyrningar i torr miljö. Testplattformen består av en simulerad pumpstation till vilken befintliga pumpstyrningar av valfri modell kan kopplas, det vill säga ett Hardware-In-the-Loop-system. De främsta fördelarna med en sådan plattform är flexibilitet, snabb feedback samt möjligheten att återskapa exakt samma förutsättningar för olika pumpstyrningar.Testplattformen har implementerats i LabVIEW på en PC som kommunicerar med pumpstyrningshårdvara via ett I/O-kort för analoga och digitala signaler.Det simulerade systemet konfigureras genom val av bland annat pumpar, pumpsump, inflöde och rörsystem. Utifrån de inmatade värdena och styrsignaler från pumpstyrningen simuleras sedan bland annat systemets flöden, energier och temperaturer. Nivån i sumpen, och övriga insignaler till pumpstyrningen, återkopplas från simuleringen.
