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.
Datormodellering av en värmelagrande betongväggs inverkan på det termiska klimatet i ett växthus
This report describes the building of a computer model that makes it possible to simulate the thermal climate in a greenhouse. The computer model is built on the physical theory of heat exchange that occur in a greenhouse, such as radiation and convective heat exchange. The model also includes the heat storage that is active in a greenhouse.The computer model is used to simulate the thermal climate in a greenhouse under three periods, winter, spring and summer. It also investigates which effect a concrete wall has on the thermal climate in a greenhouse. The purpose of putting a concrete wall in the greenhouse model is to investigate the possibility to store heat during the day and then use this heat when the temperature drops during the night.The result from the simulations shows that a concrete wall levels the big difference in temperature that normally occurs under a day in a greenhouse.
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.
Vi har i alla fall tipsbolag : En studie av möjligheterna att styra med belöningssystem inom kommunal verksamhet
Background: The use of reward systems can be of strategic importance as well as an affective mean of control for the organization in its work to achieve its goals. The municipal sector is characterized by its transparency and its responsibility for the taxpayer?s money. We therefore wonder which possibilities the municipal sector has to use reward systems as a men of control. Purpose: We intend to research the possibilities that the reward system offer as a mean of control for employees at the higher municipal level, with a special focus on commitment and motivation.

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.
Har du tid? En studie av mellanchefers handlingsutrymme på Tetra Pak Dairy & Beverage Systems AB
Mellanchefer sitter idag på en position där de är tvungna att förhålla sig till ett stort antal faktorer som påverkar dem i deras arbete. Deras situation passar därför alldeles utmärkt för att undersöka aspekter som har med begreppet handlingsutrymme att göra. Vi har med hjälp av Tetra Pak Dairy & Beverage Systems AB tagit reda på vilka faktorer som påverkar deras mellanchefers handlingsutrymme. Detta gjordes genom att inledningsvis identifiera ett antal övergripande ämnesområden som ansågs påverka handlingsutrymmet i hög grad. Ämnesområdena fick sedan ligga till grund för de kvalitativa intervjuer vi använde oss av för att få in vårt empiriska material.
Användbarheten av två modeller i två olika företag, en studie av lean production : Fallstudier vid SKF Couplings systems och AQ Parkoprint
This study is about to see whether the two models representing the strategies of lean production is to use and apply in different companies. The models are structured in two different ways in which one of them is checking the softer elements of lean production in the form of leadership and strategies. This model is called Lesat and is based on interviewquestions. The second model, called "learning to see" is about identifying flows. This, together shall then give an idea of how mature companies are when it comes to a whole in the concept of lean production, and susceptibility to use these models to their respective companies. The study is conducted in two companies, SKF couplings systems and AQ parkoprint.
Flödesekonomins dimensioner : supply chain management
It is of increasing importance to in the most effective possible way, manage and control all the transactions of raw materials, products and information that are exchanged between an organization and all its operators. These flows and the need for strategy and managing the processes of planning, implementing and control of the supply chain, has given name to the concept supply chain management. Supply chain management involves all movement and storage of raw material, and all the processes that is needed to manufacture a product from origin to consumption. Globalization, technology and increasing time and quality-based competition are all driving forces behind the concept and reasons for an increasing interest in supply chain management.The purpose of this essay is to by using a qualitative case study examine which decisive success factors that can be identified for effective supply chain management. We have compiled different theories on the subject to use for analyzing a case study Li & Fung, who is a successful supply chain management company.
Storskaligt batterilager i samband med landanslutningen i Ystad hamn
Omställningen till ett mer hållbart samhälle spelar en betydande roll för att uppnå deEuropeiska mål och klimatavtalen, 20/20/20-målen. Ett av målen anger att andelen förnybarenergi ska öka vilket ställer högre krav på elnätets kvalitét. Framtidens elnät måste blimodernare, att det genom utvecklad styrning och övervakning kan balansera ökadeeffektvariationer och därmed erhålla en ökad stabilitet, så att god samverkan mellan förnybarelproduktion och elanvändning uppnås. Redan i dagsläget finns tekniska lösningar som gördet möjligt att konstruera ett sådant modernt elnät.Projektgruppens uppdragsgivare var Ystad Energi AB som ville undersöka möjligheten attansluta ett batterilager i samband med landanslutningen i Ystad hamn.När färjorna vid kaj ansluts till det fasta elnätet kan effektbehovet i Ystads lokala elnät öka iden utsträckningen att abonnerad effekt på överliggande elnät överskrids. I dagsläget är detinte möjligt att uppgradera till ett högre effektabonnemang eftersom transformatornsbegränsade maxeffekt som förser Ystad med elenergi redan är uppnådd.För att undersöka möjligheterna till ett batterilager, har dels Ystads effektbehov ochlandanslutningens tillkommande effektbehov analyserats.
Självbild: påverkan och motståndskraft ur ett utvecklingsekologiskt perspektiv
Our paper is a study about youth and their self-images. During our practical training period we found that the problems young people had always were connected with their self-image. We therefore wanted to find out what youth believe influence their self-image. The purpose of our study was to examine young people and their self-images in a perspective of the ecological systems model. Essential issues have been what self-images young people have, what they consider influence their self-image most, how they think they can resist influence from the environment and how they would like to be influenced by the environment if they could decide themselves.
Vad ridskolor lär ut om hästens beteende
The horses have been in the care of humans for about 5000-7000 years. But even though the horses have been domesticated and artificial selected for such a long time their natural behaviours and instincts still remains. In the rich countries there are many people who have the opportunity to ride either on their own horses or at riding schools. Many of these people have not grown up on farms and have no experience of handling big animals. This can lead to implications of the horses? welfare.
Att skapa en snabb, sökdriven e-handelssajt : en studie med backend-lösningar i fokus
AbstractThis study examines the technologies appropriate in developing back-and solutions for search-driven user interfaces of e-commerce sites. The study is based on existing research in search-driven user interfaces of e-commerce sites from a design point of view, but instead the focus of this study lies within a back-end perspective. This choice of focus is a result of the gap that was encountered within research and other literature when it comes to general advice in how e-commerce sites best should build back-end solutions to support search driven user interfaces. The technologies that have been examined and compared are traditional relational databse management systems (RDMS) and the newer so called No-SQL database management systems, and also traditional search engines and the newer variant s of search engines. The study concludes that in some cases it is appropriate to combine traditional and newer technologies when it comes to databases, while the comparison of search engines indicates that there are some newer search en gines that have the ability to meet more of the needs that can be identified on the back-end solutions.Primary data consists of interviews made ?face to face? with experts on the subject and questionnaires addressed to selected e-commerce companies via e-mail.
