This thesis has been done at the Unversity of Örebro for Örebro University Hospital (USÖ). In our work we have developed a product for hearing tests to determine hearing thresholds of small children. Our product contains software and a control surface for controlling two separate screens. One of the demands was that our software could handle big file libraries. Reliability and simplicity were essential for the user.In our work we have utilized programming of both microcontrollers and Windows software.

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.

Stress is common in today?s society, but the word stress has numerous connotations. The aim of this study was to investigate how dogs are effected by stress and what the veterinary nurse can do to help dogs to avoid or at least mitigate stress within the veterinary hospital. The goal was also to see how dogs perceive the environment in the veterinary hospital and what behaviours dogs demonstrate when they enter the hospital and during their stay. Studies have shown that dogs have a reluctant feeling on entering a veterinary hospital. They can feel stressed by coming to a new environment, as well as by being put in a cage with no control over what is going to happen to them.

Eutrophication has been a problem in aquatic systems for a long time. It is well known that the key nutrient to control the eutrophication process is phosphorus. Lately, it has been possible to reverse the process and recover lakes from eutrophication.During a long time Lake Näsnaren in Katrineholms kommun, Södermanland, has been exposed of a large amount of phosphorus from the city's wastewater. The lake has a great value as a habitat of rare species but also a high recreation value for people living in Katrineholm and Södermanland. Lake Näsnaren is situated in a Natura 2000 area.

Weaning is one of the most critical events in the piglet production with problems such as growth check and post-weaning diarrhea as a result. The lighter the piglets are when the growth check occurs, the harder they have to get back to normal growth rate. Creep feeding of piglets is used to reduce the problems by increasing the weaning weight and adapting the digestive tract to a starter diet. Hodge (1974) showed that the sow?s milk can not provide enough nutrients for maximal growth rate.

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.

The purpose with this paper is to examine if tertiary education and democracy have an impact on economic growth. In order to decide how democratic the examined countries are the democracy index constructed by The Economist is used. Besides the two central theories the purpose is also to explain why these variables could affect growth and to examine direct and indirect effects. Indirect effects mean that one variable affects another variable which thereafter has an impact on economic growth.34 OECD countries are compared in order to investigate whether education and democracy are strongly correlated with BNP per capita. Therefore a statistical design is used as method.The empirical results suggest that there is significant correlation between democracy and economic growth.

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.

Det finns i management control-litteraturen en efterfra?gan pa? studier som tar ett helhetsperspektiv pa? styrsystem (Management Control Systems, MCS) och som fo?rklarar hur dessa system bidrar till effektivitet hos organisationer. Utifra?n ett contingency-synsa?tt underso?ker vi i denna studie hur kulturell styrning och prestationsma?tning som delar av MCS, tillsammans med den kontextuella variabeln osa?kerhet i omgivningen, pa?verkar hur effektiva organisationer a?r. Vi antar en systemansats och o?nskar studera relationen mellan fler variabler, och da?rfo?r tilla?mpas en klusteranalys da?r datamaterialet delas in i grupper med liknande karakta?ristika.

During the past 20 years, the price of forest estates in Sweden has raised more than the price of timber. The purpose of this study is to investigate if it, despite this development, is possible to buy a forest estate based on economic grounds. Different forest parameters will also be studied to analyse their effect on the profitability. The study is done in cooperation with the company LRF Konsult. Purchase price of 34 forest estates near the coast of Norrbotten, Sweden, has been compared to yield valuation. For the valuation, guidelines from the Swedish author Lantmäteriet was used.

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.

This thesis investigates the effect of profit growth and profitability on market capitalization amongst Nordic companies during the turbulent period 1997-2005. Our results suggest that profitability have a significant impact on market capitalization for six of the nine years studied, whereas profit growth does not seem to affect market capitalization. Consequently, our results imply that the effect of other factors on share price performance may be greater than previously suggested. These findings are only partly in line with theories on corporate valuation which suggest that market capitalizations are to a great extent driven by both profit growth and capital returns, regardless of whether the stock market is particularly unstable..

Society today is characterized by the transforming effect IT has had, the majority of the activities we perform on a daily basis involves one way or another digital technology. One area which has not yet seen the positive effects of IT is education. Despite the progress of technology, the school education has barely changed since it first saw the light of day. Our goal with this study is to investigate the possibility of implementing Gamification elements in educational environments and examine whether it could increase our young students learning motivation. We believe that this kind of implementation will have a positive effect for these young people since they have been interacting with games since they were small and are familiar with the driving force of a reward system.With this study we want to examine the opportunities and challenges that Gamification implementation brings out in a learning environment and therefore encourage and motivate our young ones to study even harder..

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.
