The company Sound Precision has developed a new Line Array loudspeaker system (VHA-40). When using this system, their customers need computer aid to get the best possible sound-quality and control of sound levels for the whole audience. The aim of this thesis is to develop a truly useful sound quality simulator for the VHA-40. The system will help the sound engineers to position the loudspeakers for optimal sound by simulating loudspeaker configurations and visualizing the resulting sound quality and quantity. To solve this a human-centered design (HCD) approach is taken to implement a system that is truly useful for the users, meaning that they will use it more and hence deliver better sound for the audience.

The research objective of this thesis was to conduct a holistic evaluation of an operational information system. By holistic evaluation we mean that an equal focus was placed on both the system system perspective and its users user perspective, in the actual environment where the system and its users function contextuality. In addition, the methodological objective of the study was to test a new research approach in a real life setting. The participants of the study were twenty newspaper journalists employed at Göteborgs-Posten GP. The information system NewsLink is a manually indexed full-text database containing all articles published in GP since 1994.

This master?s thesis was performed at PartnerTech AB in Åtvidaberg. It addresses the problem of managing test results obtained from testing electronics manufactured by PartnerTech. PartnerTech has developed a test system, called Tor, which performs tests on manufactured boards and stores the test results in files. The Tor system consists of both hardware and software part, where the software runs on an ordinary PC with MS DOS/Windows 2000.

Denna uppsats är resultatet av en studie genomförd vid Bodens Energi AB. Arbetet har genomförts på företagets värmeverk och den avdelning som handhar produktionen av fjärrvärme. I och med ett riksdagsbeslut gällande en ny lag för avläsning av elmätare kommer tillväxt att ske för system som handhar fjärravläsning av mätare både på el och på värmesidan. Vi har därför undersökt hur införandet av detta system har påverkat de anställda och vilka hinder och möjligheter som kan uppstå av ett sånt system. Det som framkommit genom studien är bland annat att införandet av systemet leder till stora möjligheter när det gäller integration och effektiviseringar i organisationen..

For a long time economic tax equalization system in Sweden has been creating dispute between Swedish communities. Despite the main purpose of the system - to reduce disparities and create equal economic opportunities for all communities ? some regions were not satisfied.The main purpose of this study is to determine what extant has equalization tax on investment spending of Danderyd municipality during 2000-2010 year period. The study is based on annual reports and personal interviews. The theoretical frame of the investigation is founded on Fjertorp's classification of investments and public choice theory.The investigation shows that there were no significant changes neither in investment spending or equalization tax during 2000-2010 period, even after the last changes of economic tax equalizations system in 2005.

This thesis work is executed at Business Unit Ericsson Test Environment (BETE), in Linköping. BETE is the department at Ericsson, which is responsible for the operation and maintenance of the company's Operations Support System (OSS). Their management system was outdated and they wanted it to be updated and it also required new features. The database needed to be replaced and the data migrated to a new database without licensing costs. The system also needed a part where employees could manage existing users.As a programming language PHP was chosen for its dynamic possibilities, platform independence and good support for database intergration.

There are several ways of conducting software testing where some may include users and others may include personnel whose work task is to execute test on systems. Although most developers and project managers understand the point of testing the system, it is not always being done and the most common reason is that there is no time for it. However, this is a false assumption as it may instead cause some bugs in the system that would not have been there in the first place if tests had been there to prevent bugs in the code.My purpose for this thesis was to find suggestions for changes in the development process in an ongoing project used by Acino and Svenska Försäkringsfabriken in order to increase the quality of the system used. In this thesis, I have approached the purpose by pursuing a case study of the two companies through observation and interviews. By doing this I acquired the relevant information to make suggestions for change.

Introduktion: Invandringen ökar konstant till Sverige och att vara född utanför Norden anses vara den största riskfaktorn för försämrad tandhälsa. Flera orala sjukdomar är en konsekvens av bristande munhygien, bakteriella beläggningar och tobaksbruk.Syfte: Syftet med studien var att kartlägga upplevelsen av den egna munhälsan, kunskapen om munhälsa, munhygienvanor samt tobaksvanor hos en grupp invandrare.Frågeställningar: Vilka är dessa personers munhygienvanor? Vilka är dessa personers tobaksvanor? Vilken kunskap har dessa personer vad gäller sjukdomsuppkomst och prevention beträffande karies, gingivit och parodontit? Hur upplever dessa personer sin individuella munhälsa?Metod: En enkätundersökning genomfördes på en skola i Stockholm som undervisar i svenska för invandrare (SFI). Totalt deltog 56 individer i undersökningen.Resultat: Resultatet visade en varierande kunskapsnivå gällande orala sjukdomars uppkomst och prevention. Beträffande munhygienvanor uppger 48,1 % att de borstar tänderna två gånger dagligen och 80,8 % använder tandkräm innehållande fluor.

Introduction: In 1998, the pension system was changed and the so called PPM system was introduced. The PPM system is partly fund-based, partly distribution-based. There are approximately 700 different investment funds to choose between, at a maximum five for each individual. For persons who are not familiar with the financial market, the choice might be difficult. The lions? part of the investors do not seem to have an active strategy.

The aim of this study was to understand how social workers perceive and understand violence and threats of violence from clients, and how it effect their working environment. It seems that the respondents understand the violence and threats of violence from clients as a result of the clients background problems, vulnerability, dependency and from ?the reason" that the client is currently in the contact with the organization. How respondents interpret the client´s behaviour based on the above-mentioned factors, seem to determine how the respondents perceive and define the violence and threats of violence by clients directed against them. Interestingly enough, although all respondents in the study experienced violence and threats of violence from clients, none of them perceived themselves as exposed at work. The answer to this is consensual.

The students have been assigned a task from Consid, were they are supposed to develop a web based platform for handling the company?s consult CV:s. The key features of the system are to simplify the administration part at mission procurements towards customers and to match qualified consultants to certain missions.Consid is an international it-consult company and have about 1000 consults working for them. When Consid makes mission procurements towards a customer they have to manually match the best consult against a certain mission, this is both time consuming and complicated.The students started the project with big visions and thoughts about how the work would be performed and how the system would be developed. After the initial meetings and the closer it came to the beginning of programming it became clear that the expectations were too big.

Travelling by train has increased during the last decades in Sweden. This has put pressure on the existing infrastructure and has created problems with delays and cancelled departures. The railway is a complex system with mutual dependencies and high vulnerability for disruptions. The situation for the railway system in the Stockholm region is today strained. The capacity is fully used.
