Genom vår utbildning till belysningsvetare vid avdelningen för Belysningslärapå Tekniska Högskolan Jönköping har vi kommit i kontakt med standard SSEN12464-1. En standard som specificerar belysning för offentligainomhusmiljöer. Det vi fått lära oss under utbildningen stämmer inte överensmed vad standarden säger, vi har därför formulerat följande frågeställningar isyfte att undersöka denna skillnad.· Hur väl uppfyller den europeiska belysningsstandarden den svenskaarbetsmiljölagens intentioner vad gäller belysning?· Kan man uppnå arbetsmiljölagen intentioner med en standard?Genom litteraturstudier och intervjuer har vi undersökt området kring dessafrågeställningar. En analys har genomförts där vi genom jämförelser av intervjuutlåtande och litteratur har fått fram ett resultat.Vi har funnit att det finns meningsskiljaktigheter mellan belysningsteknikenoch belysningsvetenskapen om hur belysning skall planeras och hur man skallkontrollera den.

An ongoing concern within the Intellectual Technological world is the issue of security. There are severe consequences if someone without permission searches a computer for secret information that was left unlocked. In order to prevent this situation from occurring, rules about password lengths or employees bringing personal flash drives into the company should be created and followed.As Internet become a worldwide phenomenon, the use of information technology is growing more than ever. With more use and accessibility to Internet, new threats against companies have also emerged. This report brings up the main issues that a company needs to regulate today.The standard for regulations and proposals for IT-security comes in a document called ISO 17799 and very complicated for those who are not experts in the field.

In order to reduce the price for, and improve the performance of automatic control systems for magnetization of synchronus generators, the possibilities of using a PC based software PLC system, Programmable Logic Controller, has been investigated. The result is a system based on the CoDeSys software PLC with runtime environment from 3S-Software, communicating with external units via Modbus fieldbus. System price is reduced from ?5000 to ?2000 and system processing speed is reduced from 10 ms for a Siemens S7 PLC to 4 ms with the CoDeSys PLC system though unsolved problems with runtime seizure caused by improper settings in the PC BIOS..

This report is focusing on problems with introducing standard enterprise resource planning systems (ERP) in businesses. A study has been carried out on a service and support department at a Swedish heat metering company, SVM North Node. The study aims to help the company become a better customer in choice and customization of a new ERP system. We make a description of the department studied and the work carried out there, on the basis of learning, knowledge and cooperation. As a final point we present some ideas on how computer systems could support their work, hoping that this will result in them making adequate demands on a new ERP system.

This essay has been made on behalf of the co-operative society Mäster Grön, which is selling ornamental plants to retailers in Sweden. The aim of this study has been to find out what added value Mäster Grön gets from their co-branding with the Swedish Seal of quality. The main topic of discussion was; how much value added does this co-branding give to Mäster Gröns pot plants? Are there differences from a customer point of view in value added between a garden center and a retail store? How much weight does the costumer put on the branding when buying a plant? Does the customer know what the values of Mäster Grön and Swedish Seal of quality mean? Two questions of lesser worth were asked to the consumers about what they thought about the protective plastic around the plant, and if they were interested in getting more information about the origin as well as the method of production of the plant. The study was divided into two parts, one in which customers were observed and one where the customers answered a survey.

In this thesis a transport system is sought after thatif realised in the city of Uppsala could provide bothwell-being to all its inhabitants and sustainability,here jointly refered to as liveability. It is found thatthe car dominated transport system that is inoperation today provides two fundamental values,namely accessibility in both time and space, whichsets it apart from other transport solutions. Thesetwo values are of immense importance for theliveability in our modern world. On the other handthe car dominated system decreases the liveabilityof Uppsala in several different ways. Some of theseproblems, it is argued, could be solved within thecar system, through the adoption of moreenvironmentally friendly cars etc., but otherproblems are inherent in the car system and willremain no matter what changes are made.

Because of increasing demand of power on Malmbanan the capacity of the existing wires which supply the trains must be increased. This increases the stress on the existing poles and for this reason the system for supplying the loads along the railway is to be removed from the poles and be replaced by some other system. This thesis is a study on a two-level low voltage (1 kV and 0.4 kV) electrical system with the aim to investigate if it can be an alternative to the system used today taking into account the voltages, fault currents and costs.In this thesis the following tasks have been performed:? Gathering of data? Description of basic theory? Loadow and fault current calculations of the system with MATLAB? Life Cycle Cost estimate of the system? Analysis and conclusions from the resultsThe results show that the new system can be an alternative to replace today's system. The simulations and calculations show that the voltage drop is at an acceptable level and that the fault currents are large enough to supply a safe disconnection if a fault occurs at the far end of the system..

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.

Denna rapport beskriver processen bakom utvecklingen av ett system som hanterar bokningar av elbilar inom ett avgränsat område, exempelvis en stad som Göteborg. I Sverige finns ungefär en bil per hushåll, av dessa bilar drivs majoriteten av fossila bränslen som använder förbränningsmotorer vilket i längden innebär föroreningar i luften, samt en hög bullernivå. För att reducera dessa problem syftar projektet till att skapa ett system för en elbilspool och mjukvara för att stödja systemet. Den mjukvara projektet ämnar sig att utveckla består av en webbapplikation, en Androidapplikation samt ettAPI som på enkelt sätt möjliggör hyrning av elbilar. Med hjälp av framtagna användningsfall utvecklades mjukvaran.

This paper discuss the possibilities to improve the Swedish political nomination system. It brings up some of the values and norms that can be used to change the existing system. Values as openness, the demand of responsibility and also if there is values from the American spoils system that can be used in the Swedish system. A minor purpose is to discuss the part of the parliament within the nomination process. To investigate this I have some theoretical starting points and a self constructed analysis tool.

Testning är en viktig process vid tillverkning av alla typer av system. Traditionellt har testning utförts föratt verifiera att ett system fungerar på ett korrekt sätt. Vid tillverkning och testning av kryptomodulerräcker det dock inte med att verifiera att systemet fungerar korrekt utan testerna måste även visa attsystemet är tillräckligt säkert d.v.s. att det uppfyller de säkerhetskrav som användare och utvecklare ställerpå systemet.I de flesta fall är det dock inte möjligt att bevisa att ett system är säkert och felfritt då det ofta finnsoändligt många attackmöjligheter och oändligt många insignalskombinationer (testfall). För att visa att ettsystem med så stor sannolikhet som möjligt är säkert och felfritt krävs att testaren kan välja lämpligatestingsmetoder och vettiga delmängder av testfall att utföra.

With the advance in computer and network technologies, multimedia systems and Internet applications are becoming more popular. As broadband network is prevailing, more clients are able to watch streaming videos or to play multimedia data over the Internet in real-time. Consequently, there is an increasing demand in the Internet for streaming video systems. As the run-time environment of such applications tends to be dynamic, it is imperative to handle transient overloads effectively. The goal of this work is to develop an algorithm that would provide a robust and controlled behavior of the video system so that important data is delivered on time to the video clients.
