Att mäta eller inte mäta : en studie om fo?rha?llandet mellan prestationsma?tning och kulturell styrning i mer eller mindre osa?kra omgivningar
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.
Low Temperature Waste Heat Solutions : with proposals for energy technological actions based on Scania?s building 64
The report comprises two separate parts:part 1: Temperature needs for district heating in the paint shop for axles in building 210part 2: Energy and low temperature waste heat solutions in heating and cooling systems for building 64 with surroundingsThe paint shop for axles in part 1 has air quality requirements in places for coating of axles. Toachieve desired air properties there are different process ventilation systems, which consist ofventilation coils for heating and cooling, plus air humidifier. The ventilations coils for heating usedistrict heating. Today the ventilation coils use water of 100°C to achieve necessary air demands inthe coating boxes. This part of the report investigates whether the existing system would achievethe air requirements with a water temperature of 75°C instead of 100°C in the ventilation coilsduring the coldest parts of the year.
Utvärdering och jämförelse av olika fälttester för fotbollsspelare
Different field tests are currently used in a wide extent in different levels of soccer teams. To be able to assess the players? physiological status the tests must have high validity, reliability and external validity. Many different tests have been developt, but currently only five of these tests are most commonly used: Yo-Yo intermittent recovery test (YIRT), Yo-Yo intermittent endurance test (YIET), Multi-sprint-test, Beep-test and Cooper-test. Presently there is no definitive conclusion regarding which of these tests is most suitable for soccer players.
Nyttjande av korsningar i mjölkproduktionen
Farmers? main reason for crossbreeding dairy cows is that they have seen a decline in functional traits, especially in the Holstein breed. Throughout crossbreeding, the farmers can combine functional and production traits of different dairy breeds and utilize the heterosis effects which emerge when two or more breeds are crossed. Results from different studies with Holstein crossed with Jersey, Brown Swiss, Normande and Scandinavian Red have shown that the crosses had higher fertility, longer productive life, had fewer stillborn calves and had easier calvings than purebred Holstein. The Holstein crosses have shown very good results and sometimes even better than the purebred Holstein for fat production, which gave higher amount of energy corrected milk (ECM) and higher income for the farmers.
Styrning av grafisk färgdisplay
This master thesis is a result of the work carried out for Research Electronics at Siljansnäs. The company develops customized electronical systems. Because of the rapidly increasing interest in colour displays there has been a desire within the company to represent information from sensors and electrical systems in a more advanced way.Due to the mentioned reason above we were given the assignment to solve how a colour display using the STN technique works. The technique is used by small displays, the size of QVGA. Our ambition of this diploma work is to develop a fully functionally test prototype to evaluate the LCD (Liquid Crystal Display) and the LCD controller.

Är sociala medier mest ett hinder? Ungas lärande i sociala medier
A large part of the daily life today means being active online and to take part in the interactions that occur there. The accessibility which social media brings, means that you can reach and be reached in several ways and there are many different ways in which information can be disseminated. Social media supports the learning process. The aim of this study is to examine how upper secondary schools students' use of social media and how it can be used as a tool for informal learning. Our study is based on the socio-cultural perspective where interaction and social cohesion is a big part.
Mätning av Mikroläckage i Dentala Implantat
Osseointegrated titanium implants have become a commonly used method in edentulous jaws and today there are success rates in the magnitude of 82 % in the lower jaw and 98 % in the upper. During first year after implantation a fully normal marginal bone loss of 1-2 mm occurs. If the bone loss continues there is a risk of implant failure. High tensions in bone and inflammation caused by bacteria are possible reasons for this problem. It has been shown that a leakage of bacterias occurs between the parts of the implant and there are theories that this has effects on the marginal bone loss.
The aim of this thesis has been to increase the knowledge about microbial leakage with help of in vitro tests and virtual simulations.
Från organisationsteori till MTO-analys? : -en fallstudie om fyra chefers arbetssituation
The background to this report is the author?s ambition to understand individuals? work situation, how it?s formed in interaction between the individual and factors in the work-setting. Such an ambition is well in line with the concept of Human-Technology-Organization (HTO), a cross-scientific approach that puts a system-oriented perspective on how human, technolog-ical and organizational factors interact within work systems.The aim of this report was to explore managers? work-situation and generate an understanding of it from an HTO-perspective by using an organizational model as a framework for an interview guide and to analyze the work situation from an HTO-perspective following the ques-tions at issue:1. How does the managers experience their work situation?2.
Mekanisk integration av en IR-detektor i en Stirlingkylare
The master thesis ?Mechanical Integration of an IR-detector in a Micro Cooler? has beenperformed at FLIR Systems AB in Danderyd. FLIR Systems is a world leader in the design,manufacture and marketing of thermal imaging camera systems.The thesis project is divided into to two areas, Production Method and Noise.The Production Method concerns the positioning of a detector on the cold finger within the IRcamera.The detector has to be positiond with very high accuracy at the center of the cold finger,so it can be placed in line with the optical axis to avoid movement of the picture during zooming.The positioning of the detector is at present done with the help of specially designed guides on aplate on top of the cold finger. The design workes well but the special machining needed for thisplate is very expensive.The goal concerning the production method was to derive a new more cost effective method forthe assembling and positioning of the detector on the cold finger by replacing the guides on theplate with a reusable equipment or some other alignement operation.Several concept ideas have been generated with the help of concept generation methods in theform of concept classification trees and concept combinational tables. Two of these conceptswere selected to be further refined.

Utvärdering av simulatorer och emulatorer för inbyggda system
Uppdragsgivaren Saab Electronic Defence Systems i Jönköping erbjuder ett flertal produkter främst inom avioniksystem. För att kunna utvärdera och kontrollera produktens design i ett tidigt skede så kan en simulering av systemets beteende och att felsöka så tidigt som möjligt vara ett möjligt alternativ. En systemsimulering kan innebära att mjukvaruutveckling och felsökning kan påbörjas långt innan hårdvaruprototypen är tillgänglig, med samma storlek och komplexitet som systemet.Andra fördelar med simulering är att det går enklare att fastställa orsaken till systemkrasch, hitta de längsta exekveringstiderna och göra felinjiceringar. Syftet med detta examensarbete är att testa och utvärdera hur simulatorer och emulatorer är som utvecklings- och testverktyg.Rapporten innehåller en marknadsundersökning där tio stycken emulatorer och simulatorer hittades. Av dessa valdes två stycken ut, Wind River Simics och Imperas OVPSim.

Contemporary Challenges of Public Pension Systems and Their Effects on Pension Reform Choices in European and Candidate countries
The process of European Integration and creation of the single market revealed many questions and boundaries on the development and improvement of the European Social Policy. Pension?s sustainability has become the priority issue especially during the EU enlargement processes. Different policy instruments and institutions available to governments of Member States in realization of social objectives resulted in a growing diversity of pension polices which produced different combinations of public and private provisions - ?private-public hybrids? , with the state exercising different degrees of influence in their development.
