Till följd av globalisering och en växande konkurrens ställs det i dag allt större krav på organisationer. För att möta den hårdnande konkurrensen är det vanligt att företag implementerar olika kvalitetsprogram. Dessa förändringar ses som nödvändiga åtgärder för att kunna bibehålla marknadsandelar och vara konkurrenskraftiga. Genom att införa Lean-verktyg och arbeta med ständiga förbättringar minskar riskerna för att produktionen läggs ned eller flyttas till lågkostnadsländer.Som examensarbete har författarna valt att studera ett av dessa Lean-verktyg som används för ställtidsreducering. Verktyget benämns SMED och står för ?Single Minute Exchange of Die? vilket syftar till att öka maskintillgängligheten genom effektivare verktygsbyte mellan olika produkter.

The problem being examined is the disturbing noise that is created in an open plan office on a company working with a creative process, such as a newspaper or a communications agency. The purpose of this study was to examine the needs for today for a sound absorber in open offices and create and design a design proposal. The aim is also to develop a marketing material the product proposal. The problem has been broken down into the following questions:- How does the user look at the need of a sound absorber in an open offices solution today?- Does an interior designer apply sound absorbers when they furnish the intended environment? - How can a design that meets the needs that exists be achieved and to speak the user?The study is based on three choice of methods a literature review on selected topics that relate to the topic, an interview with an interior designer to explore how an interior designer applies absorbers in open plan office and finally an extensive survey that treats the user's needs and appropriate appearance for the product proposal.The design process has undertaken the following methods, design brief, requirements specification, functional analysis and sketches to produce the final product proposal.

The decision of the European Commission to block the merger between Volvo and Scania in the late 90?s became the starting point to the debate of the possible discriminating effects of the European merger regulation. Especially since the Commission a few years earlier had approved of the merger between Mercedes-Benz and Kässbohrer on the German bus market, where the conditions for competition had been similar to those at hand in the Swedish case. The issue that was and still is in focus is whether the European merger regulation is more difficult to pass for large companies situated on a smaller domestic market than is the case for their competitors of corresponding size but situated on a larger domestic market.This thesis aims at examining what the judgement of the geographical relevant market means for the application of the Merger act. This is being done from two perspectives.

The importance of energy- and environmental issues has increased, and the work towards reducing carbon dioxide emissions plays a major part. The European Union has set up goals for the membership countries to work towards this to happen. The carbon dioxide emissions in Sweden have been reduced the last few years, but there is still a lot to do. About 30 per cent of Sweden?s carbon dioxide emissions generate from energy usage related to housing, this is why the housing sector is of interest to examine.

Förmågan att dela med sig av kunskap inom organisationen och att vara en innovativ organisation är idag avgörande för ett företags konkurrenskraft. Organisationens förmåga att lära är inget som uppkommer slumpmässigt och det har visat sig vara möjligt att skapa kreativa och lärande miljöer genom ett konsekvent arbete. Litteraturen visar på en rad element att beakta för att vara en lyckosam lärande organisation. En av dessa är hur organisationen strukturerar sina resurser. Det har visat sig ha stor betydelse på vilka nivåer besluten tas och hur nära besluten medarbetarna känner sig.

The real estate company Ihus is facing an expansion of its comfort cooling in Noatun,Uppsala, to provide the buildings in the block with cooling. The buildings in Noatunare mainly used for office premises, where the requirements for an accepted indoorclimate is great. However, it?s uncertain whether Ihus should continue, as currently,producing comfort cooling by themselves using a compressor chiller, or if they shouldconnect themselves to Vattenfall?s district cooling net.The purpose of this report is to examine which technique of cooling is best suited forIhus and their buildings in Noatun. It should also work as a guideline for othercompanies facing the same problem as Ihus.

Variation in tuber quality within a single field was one of the motives for a pilot study in Halland, in south-western Sweden conducted during 2002. Quality problems in potatoes have been increasing due to the aggregation of several small fields with different land use history into larger farm units, which are heterogeneous in soil properties and fertility. The study in Halland indicated that both the uniformity and the mean size of tubers may increase from site-specific K fertilization, whereas total yields may be unaffected. The results from this pilot-study with site-specific fertilization showed that tubers reached a more uniform quality and gave a more uniform mean size, while the total yield wasn't affected at all. Site-specific K-fertilization has been applied for some years in Halland with good results. The aim of this study was to test this technique in another potato growing area.

Lower energy use in buildings is a result of increasingly stringent energy requirements across Europe. When conventional district heating technology is used in areas with low energy consumption heatlosses do not fall even though the amount of energy delivered is reduced. This reduces income for thedistrict heating company. To maintain their economic viability the district heating companies? majorchallenge is to implement new solutions that minimize heat loss.

Simulation of different systems can be done using a graphical model description of the system based on block diagrams. The simulation software Matlab/Simulink offers a lot of possibilities to describe a huge number of systems, which can be linear as well as nonlinear. The simulation using Matlab/Simulink is done by integration based on different kinds of numerical methods.When nonlinear Simulink-models are simulated, it is often interesting to apply a Kalman filter to handle the noise that may occur within the process as well as corrupting the measurement. However, application of such a filter leads to an extensive time-consumption despite using fast computers. The reason is that the existing Matlab functions are not constructed for time optimal evaluation.

Vid adhesiv cementering, så kallad bonding, rekommenderar fabrikanter att glaskeramers cementeringsyta etsas innan applicering av silan. Att värmebehandla silan med respektive utan etsning, har i tidigare studier visat en höjning av bindningsstyrkan mellan olika material. Den litiumdisilikatbaserade glaskeramen IPS e.max® Press har funnits på marknaden sedan 2005 och få studier har gjorts på ytbehandlingar och dess effekter på materialet och bindningen till olika material. Syftet: att undersöka om ytbehandling med värmebehandlat silan ger en högre bindningsstyrka till adhesivt cement hos en litiumdisilikatbaserad glaskeram, jämfört med kombinationen etsning och silanisering. Material och metod: 12 litiumdisilikatbaserade keramiska block pressades. Blocken delades parvis in i sex grupper och ytbehandlades med etsmedel och/eller silan med eventuell påföljande värmebehandling. Blocken cementerades samman varpå mikrostavar sektionerades fram, som sedan termocyklades. 10 provkroppar ur varje grupp valdes ut för ett microtensile bond strength test. Frakturytorna bedömdes i mikroskop.

Detta examensarbete har genoförts vid AB Sandvik Coromant i Gimo på avdelningarna GVH2 och GVH3 under perioden oktober 2004 till mars 2005. Målet med arbetet var att komma med förslag till förändringar för att öka produktiviteten för avdelningarna genom bl.a. tillverkningsstrategiska och laoutmässiga förändringar. Arbetet bedrevs i fem huvudsakliga block: kartläggning av nuläge, analys av nuläge, litteraturstudie, framtagning av förslag, analys och utvärdering av förslag. De första två blocken gav oss en blick över hur väl den nuvarande produktionen överensstämmer med den planerade produktionsstrategin.

Background: The most energy efficient houses today are so called passive houses. These houses achieve high energy-efficiency partly by having well insulated walls. U-value describes the amount of heat transfered through a building element, the more insulation, the smaller U-value. A typical passive house wall have a U-value of 0.10 W/m2,°C. The passive houses are primarily made as small family houses and not as a block of apartments.

The main purpose with this thesis has been to study the design philosophy of Bruno Mathsson, how he worked with his houses and the landscape surrounding them and which kind of inspiration sources he had. My work started when I during the autumn 2004 got involved in an existing project related to one of his glass houses. The glass house is situated in Kosta and has during the last fifteen years suffered from so much vandalism and decay that it has become a problem for the municipality of Lessebo. The intentions are to restore the house and to transform it to a center for Swedish design, also containing a store and a café as well as hosting one apartment for scholarship students. My task in this project was to form and develop the outdoor environment in connection to the house.

Ringhals AB upplever att de har stora underhållskostnader på tre kompressorer som försörjer system 751 med tryckluft. Rapportens syfte är att ta fram ett beslutsunderlag för att kunna motivera en nyinvestering. Underlaget ska innefatta bl.a. en underhållskostnad för kompressorerna, vilka de vanligaste felen är samt en rekommendation till lämplig utbytesinvestering.En sammanställning av underhållskostnader har genomförts för att sedan ställa i jämförelse med en nyinvestering. Då driftsäkerheten för Ringhals AB är av största prioritet, undersöktes vilka de vanligaste felen är som uppkommer samt hur ofta underhållsinsatser krävs.

The essay examines through semi-structured interviews the experiences of overcrowded housing, as they are portrayed through the eyes of children aged 8 ? 14. Overcrowded housing has an effect on children?s school performance, general health and is often linked to less capacity for normal social consumption. Yet there seems to be little done in terms of interrogating children about how they perceive their situation here and now.
