This thesis has been made in cooperation with Forsheda Stålverktyg AB which develops and manufactures injection moulds and diecasting tools. The main concern has been their Trading-system which provides them with considerable amount of quality lost function.Focus has to however be put on the analysis of the Trading-system due to the fact that this has previously meant various quality issues for the company.This thesis treats quality assurance of the Trading-system, identification of the problems in the process and improvements of these problems.Quality assurance is carried out when a company detects that their quality based costs become too high. Quality based cost are? the costs that would disappear if a company's products and its different operational processes were absolute? (Sörqvist, 2001 p.30, free translation from Swedish). High quality based costs often result in increased quality problems, which can lead to substantial economic loss for the company.This work has resulted in a thorough review of the Trading-system whereupon problems have been identified.

Computer based information systems play an important role in modern military combat vehicles. The crew needs to be able to quickly get information about both the vehicle and its outer surroundings in order to quickly make the correct decisions. In this report, we describe the development of a prototype new information system for the BvS10 vehicle, manufactured by BAE System Hägglunds AB in Örnsköldsvik.An important aspect of the system is the time it takes from the point that the information is generated by the vehicle sensors until it is presented to the user. The system must be able to ensure that it never displays information that is out of date. Thus, it is important to create a layer and component based architecture for the solution, making it possible to control, in detail, the information?s age as it moves through the system.

Diagnostika verktyg, som t.ex logik för att avgöra om en server fungerar normalt används idag av många företag för att underlätta underhåll av datorsystem och säkerställa driftsäkerheten. TietoEnator GSS ser att ett system för att utföra diagnostik på egenutvecklad programvara, t.ex serverprogramvara för e-tjänster, skulle kunna effektivisera driften av dessa tjänster. Detta examensarbete beskriver utvecklingsprocessen och implementaionen av delar av ett sådant system. Rapporten behandlar också till viss del diagnostikverktyg som finns idag och lite om hur framtida system för att underhålla datorsystem kan se ut..

The aim of this study was to compare the Query-by-Humming systems Midomi, Musicline and Tunebot regarding their retrieval effectiveness. The aim was to see if there were differences between the systems but also between the user groups common users, musicians and singers. Query-by-Humming system means that the user sings a tune that the system then use to find the right melody.To compare the systems and their users, queries where collected from the different user groups and replayed for the systems. Mean Reciprocal Rank and Friedman test was used to do the comparison.The results showed that the system did not achieve equivalent and that there were no difference between the user groups. The Mean Reciprocal Rank showed that the systems had very different retrieval effectiveness, where Midomi was the system with best result and Musicline with the lowest result..

Den amerikanske flygvapenöversten John A Warden III har lagt fram en teori om att man kan se på fienden som ett system av system för att hitta hans svagheter. Teorin bygger på att skapa en bild av fienden genom en fördefinierad indelning i subsystem bestående av fem ringar. Denna bild skall därefter kunna brytas ner i ytterligare subsystem bestående av samma fem ringar som till slut avslöjar fiendens tyngdpunkter. Uppsatsen prövar om Wardens teori går att applicera på Al-Qaida..

This thesis investigates if a system for small scale electricity production located in anurban environment can be profitable. The work has been divided up into two parts,one extensive literature study and one case study. The purpose of the literature studywas to investigate the area, resulting in a choice of which technology to be studied indepth in a case study.In the case study a system containing small scale wind turbines and photovoltaicsmounted on Gränby Centrums roof was examined. From data containing wind power,wind direction and total irradiation, possible production from a system weresimulated. Three products of each technology were examined in the simulations.From the simulated production an economic analysis was carried out, this toinvestigate if a system is profitable.

The aim of this Master thesis is to investigate the similarities and differences between a traditional and a new classification scheme. Two classification systems are compared, "The Swedish Library Classification System" the SAB-system - and Yahoo!. The SAB-system has been used in Swedish libraries since the beginning of the 20^th century, and Yahoo! has been online since 1994. Yahoo! has a Swedish version of its international original, which is used in this study to get a similar starting point with the SAB-system. The method used for this is a content analysis, which in this case is not a quantitative analysis.

Detta arbete tar upp iden om att datorspel kan användas som ett hjälpmedel för att förstå och hantera komplexa system, för den enskilde spelaren såväl som för forskare. Arbetet fokuserar på ett antal kritiska faktorer: möjligheter, problem och frågeställningar, samt tar upp en diskussion kring möjligheten att se datorspel som världar, lika verkliga som vår egen, då vi ser på det från en position innanför systemet, genom speljaget som en agent i den virtuella världen, och vilka implikationer detta kan få för hur vi kan lära oss att förstå och hantera komplexa system.Vi lever i en verklighet i vilken vi omges av komplexa system, både sådana vi skapat själva och sådana som finns naturligt. Det är en paradox att den teknologiska utvecklingen som strävar efter att förenkla vår tillvaro också undantagslöst komplicerar den. Att försöka hitta nya vägar att kunna lära oss att förstå och hantera dessa komplexa system är därför viktigt, och här presenteras datorspelet som ett tänkbart redskap för att göra just detta..

The purpose of this qualitative thesis is to describe and analyse the implementation of an education system in the newly independent state, Timor Leste. One question to be discussed is whether an emergency phase is still going on in the development of a functioning school system, or if Timor Leste already reached a capacity building phase? Via the participant's answers in field observations and interviews, the study analyses the clashes between generations, social classes and different levels in relation to the choice of Portuguese as an official language and the international environment in the country. The thesis concludes that a lot of work remains in creating a fully functioning education system. We enjoyed the writing - and hope you will enjoy the reading!.

The purpose of the study is to investigate the possible effects of an unstable ventilation system and its influence on energy use and thermal comfort. The report also explores how qualified personal working with HVAC view and handles system control.In order to meet the requirements in energy efficiency and a comfortable indoor climate control regulation is a prerequisite. With optimized increased complexity of the climate systems, it becomes more challenging to control the system and the risk of unstable control increases. No previous studies about what affect an unstable system can have on energy use and thermal comfort have been found.The report is based on several tests were the controlling variable has been increased until the system becomes unstable. Two different types of unstable systems have been investigated.

At Saab Aerospace in Linköping, components for measurement systems to the fighter aircraft JAS 39 Gripen are developed. In this activity you sometimes want to record the traffic transmitted on the data busses that connects different sys-tems. This traffic on the data busses is using the military standard MIL-STD-1553. This project has aimed to create a system for recording and sending 1553-data. The system is used on an ordinary personal computer, equipped with a recon- figurable I/O card that among others has a programmable logic circuit (FPGA).

 This report is an evaluation of Peab's purchase and call-off system, PIA.PIA is used to order goods for Peab's construction sites. The background to the work is that users of the system have understood the system cumbersome to use when purchasing goods for construction sites. The evaluation was carried out by the interviews and tests with users of the program, in this case, supervisors and site managers at the company. Ten users of the system were interviewed and eleven people have carried out a test order.The focus is primarily on the test order that users have implemented, which has been clocked and analyzed for time and cost. The evaluation is also a user analysis concerning how the users perceive the program, mainly in terms of usability, functionality and benefits.The result of this report shows that PIA is economically profitable to use for the purchase of goods for construction sites.
