To achieve an optimal combustion, an even air/fuel ratio in the combustion chamber is required. An optimal combustion leads to reduced amount of emissions due to a more complete combustion, which is an important matter because of the sharpened environmental laws. This can be attained, among other things, by applying entirely variable cam times. To optimize the engines efficiency and its emissions at all workloads and speeds, an active valve control can be applied. This means that the intake and exhaust-valves can be opened and closed at any time, independent of the crankshaft position.

The company GEMS PET Systems produces cyclotrons which is a type of particle accelerator. The cyclotrons create log files that are analyzed by the company?s employees for different purposes like troubleshooting or installation. The purpose of the project is to with a usage-centered design method create a paper prototype of a tool that will help the employees to analyze the log files in a more efficient way than earlier.The result shows how the usage-centered design method was used to create the paper prototype and how the user interface was created according to human-computer interaction (HCI)..

This bachelor thesis in science Informatics contains the qualifications for the applying of IT in education for students in elementary school, grade 1-3. By empirical case study on an existing elementary school, whose success on IT use is noticed, describes how to apply IT in the classroom in an adequate way. We look at different theoretical frameworks in interaction and design of systems designed for learning purposes, and satisfies their specific needs and situations within the classroom's four walls. The current lack of statistical measurements on students' results and effects of the use of IT in teaching, prevents further improvements. If we simultaneously work to develop more well-designed systems that are designed for this purpose, it is possible that the effects become more and better.

Syftet med studien var att belysa hur motivation på arbetsplatsen kan betraktas från ett inre och yttre perspektiv, med utgångspunkt från ett antal specifika faktorer såsom samhörighet, kompetens, autonomi och kontroll i tillvaron. 126 respondenter, 99 kvinnor och 27 män besvarade en enkät som bestod av demografiska frågor, frågor kring chefens stöttande av autonomi, frågor om samhörighet, kompetens och arbetsmotivation samt ett testbatteri bestående av IMI scale, Work Extrinsic and Intrinsic Motivation Scale och Locus of Control. Studiens resultat visar att chefens stöttande av autonomi påverkade de anställdas inre arbetsmotivation positivt. Studien visar även på att det finns ett svagt samband mellan inre arbetsmotivation och tillfredsställelsen av de anställdas behov av autonomi och samhörighetAbstractThe purpose of this study was to see how work place motivation can be seen from an intrinsic and extrinsic perspective, with starting point from specific factors such as relatedness, competence, autonomy and control. The 126 respondents of the study, 99 women and 27 men, answered a questionnaire that consisted of a few demographic questions, questions about if the boss is supportive of autonomy, questions about relatedness, competence and work place motivation.

Ethiopia is the country with most livestock per capita on the continent of Africa. There are 34.5 million cattle that are used for drought, meat- and milkproduction and 85% of the population rely on agriculture for their survival in some way. Milk is produced in four main systems, through pastoralism in the lowlands, in mixed crop-livestock systems in the highlands, in and near big cities with only one or two cows, and in intensive farming systems. There are 17 cattle breeds in Ethiopia and some of them are more suitable for milk production than others. Several environmental and economic problems arise from livestock holding in the country, for example overgrazing, low production due to feed shortage, low quality of the avaible feed and non-existing breeding programs.

SammanfattningDenna uppsats beskriver design och implementering av en mer effektiv metod att styrakameraförsedda radiostyrda markfordon (UGV av engelskans Unmanned GroundVehicle). Det åstadkoms genom att införa samma kontroller som är vanliga i actionspel iförsta persons perspektiv, så kallat Free Look Control (FLC). Miljontals spelare kommeratt känna igen och vara bekväma med styrprincipen, vilket borde reducera dengenomsnittliga träningstiden samt förbättra prestationsförmågan. FLC gör det möjligt föroperatören att kontrollera kamerans läge direkt istället för via fordonet den sitter på.Detta görs genom att i mjukvara sammankoppla fordonets och kamerans rörelser.Utöver författandet av denna uppsats byggs en fungerande UGV-prototyp som kanstyras enligt både FLC och dagens standard, Tank Control (TC). Detta gör det lätt attdemonstrera skillnader mellan metoderna.Arbetet utförs åt institutionen Flyg- och systemteknik inom FOI, Totalförsvaretsforskningsinstitut, för att demonstrera och marknadsföra konceptet att använda FLC förstyrning av obemannade markfordon.Nyckelord: Odometri, Kalman filter, UGV, Unmanned Ground Vehicle, obemannademarkfordon, FLC, Free Look Control, FPS, First Person Shooter, fjärrstyrning..

Swedish school has for the last decades been using quality management as a method for improvement. Quality management is an enormous work and the whole school staff needs to be involved. The management consists of several parts like planning, surveys and interviews, analysis of the replies and setting up new goals. Parents, children and teachers are nowadays accustomed with quality surveys. The last few years these quality surveys have been computerized, but they still look almost the same, using little interaction with the respondent.I have had the opportunity to work with the company KMF Ventures, which has a vision that entails a more interactive web survey.

Forskning har visat att self-efficacy, självkänsla, KASAM och locus of control alla har en effekt på graden av upplevd stress. Dock inte alla tillsammans, vilket denna studie avsåg att undersöka samt deras inbördes relationer och vilken variabel som predicerar stress bäst. Högskolestudenter (n = 65) svarade på varsin enkät. Resultatet visade att alla variablerna hade signifikant negativ korrelation med upplevd stress. Ju högre nivå på variablerna desto mindre stressade var studenterna.

Talented people are recognised as being the most important corporate resource over the next twenty years and a competitive compensation system is an important tool in attracting and retaining talent. Traditional pay systems are recognised as being neither cost effective nor motivating people to do more. Often these systems do not contribute to strategic objectives. This study outlines what constitutes an intelligent remuneration system that will enhance the mind value added by knowledge workers, reward knowledge creation, and contribute to organisational strategies..

The aim of this study was to investigate how the process of implementing a quality management system for food safety was handled in four different food producing companies in Sweden. The aim was also to analyze what difficulties the companies face and the possibilities that arise when certified. Furthermore, the reason for implementation was discussed as well as the main expectations on the certificate. Implementing a quality management system is a good way of ensuring the quality and hygiene of the food production and it also increases the traceability of food products through the whole food chain. A food safety standard provides a method of preventing problems and crisis and it can also help to handle requirements from authorities, the market and others.

The Swedish National Heritage Board (RAÄ) is the agency of the Swedish government responsible for heritage and historic environment issues. During the last couple of years the agency has implemented a new management control system, the balanced scorecard, originally developed for profit driven organizations. Organizations within the public sector have other objectives than profit seeking organizations, and there have been difficulties in applying the balanced scorecard model in the public sector. Therefore we find it interesting to examine the reasons behind these difficulties and believe that some answers can be found in the identification process of the balanced scorecard. Therefore we aim to perform a case study of RAÄ and explain how the identification process of the components of their balanced scorecard can affect further usage of the model as a management control tool.

AbstractAre we always aware of our actions and the affect they have on our environment? With this study we are exploring a phenomenon, called Jantelagen, which have affected the Swedish society for a long time. It is a phenomenon that where brought to life officially in the 1930?s by an author called Aksel Sandemose. We want to know if Jantelagen still exist in the society or if it has faded to the degree that it is no longer in use.

In system development it is today increasingly common to use a model-based system development method. These methods that are suited for Agile work with simple and quick updates and implementations of new applications in systems conform to the requirements that are becoming more important today, namely more flexible and less expensive system that still maintain high quality and safety.A company that has been working with this type of system development method for a long time is Genicore AB, which also has developed their own tools and model language in order to better model the information management systems in complex and abstract operations. Genicore AB is trying to spread their method other developers and have therefore taken the initiative to start this study. The method is evaluated and tested by two students with relatively little experience in model-based systems engineering in order to gain a new perspective on how the method functions. The method has been applied to an educational activity in order to test it in a new domain, and this led us to our research question;?What criteria are of particular relevance in the implementation of a MBSD method on on complex businesses??Through literature reviews and interviews, we formed an idea of how model-based system development works from a theoretical perspective, and then continued to the case study conducted on the educational activities at the faculty of IT at University of Gothenburg.

En prototyp till en förarstol för det militära fordonet SEP har tagits fram av tidigare anställda på BAE Systems Hägglunds AB i Örnsköldsvik. Stolen måste uppfylla en omfattande mängd krav då den är tänkt att användas i ett stridsfordon, och av personer av varierande storlek. Den nuvarande prototypen för stolen anses dock vara för dyr och det har dessutom framkommit en del klagomål på konstruktionen. Stolen måste därför göras om så den blir både billigare och bättre. Genom att ta del av tidigare genomförda tester på BAE Systems, samt genom att göra nya tester upptäcktes det dels vad som var dåligt och därmed behövde göras om, och dels vad som var bra och kunde tänkas behållas.
