Examensarbetet är utfört på Albin Components i Kristinehamn som med gamla anor inom motortillverkning och komponenter till motorer har specialiserat sig på transmissionskugghjul till tung fordonsindustri.Projektet har gått ut på att analysera ställtiderna på kuggcellerna 3, 6, 8, 5 och 7. Förutsättningen för att använda produktionsfilosofin Lean Production och dess bruk av små batcher är att ha korta ställtider. Ställtiden är den tid som en maskin står stilla under bland annat byte av verktyg inför körning av en ny order. Då inget produceras under ställ är det en spilltid och som all spilltid måste det reduceras till ett minimum.SMED- metoden (Single Minute Exchange of Die) är en metod för reducering av ställtid där stället delas upp i OED (Yttre ställ) och IED (Inre ställ).Analysen har till stor del kretsat kring tidsåtgången för mätning i mätrummet som är en stor del av ställtiden. Dessutom undersöktes möjligheten att minska tidsåtgången vid själva ställets utförande och kommunikationen mellan operatörerna och mätrummet.För att uppfylla målen har kvalitativa och kvantitativa undersökningar gjorts.

The background for my thesis is the fact that with rising electricity and oil prices it becomes interesting to calculate on alternative heating systems. I have chosen to calculate upon my parents? farm, which today heats the dwelling house with wood. This is very time-consuming work, time which could be spent on other work. The main objective for this study is to compare three different heating systems to decide how they differ considering effort and cost. The result from the calculations was that grain-heating system demanded the least amount of work, but the total cost was a little higher compared to chips heating. Chips heating required half as much work as today?s wood heating and had a little lower total costs compared with the corn heating. Which system to choose largely depends on how the own work is valued.

Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

The purpose of this study was to investigate the problems of building a new region in the Southeast part of Sweden. The idea of a big south Swedish region is brand new; no former studies in this area have been done before. The main analytical focus of this study is legitimacy, identity and democratic credentials. The study has been carried out by interviews with several leaders in organizations working with the collaborations of the smaller regions in to the big region. The method of this study has been a single-case study and dialogue interviews.

The attitudes towards nature conservation in forestry are based on the individual forest owner. The theme of the interviews is the opinion on nature conservation in forestry. The purpose of this study is to identify if there is any difference in attitude to nature conservation in forestry according to the age of the forest owner. The study discusses different factors that affect the private forest owners consideration of nature conservation and give an insight in different generations attitude to nature conservation. Other topics that are discussed is if future change of generation will change the consideration of nature conservation in Swedish forestry and what is needed to enhance the interest in nature conservation among forest owners.This study is the result of interviews with a number of forest owners in the county of Uppsala, Sweden.

This study examined parenting in relation to ADHD. The key point of the study was to let parents who experience an ADHD diagnosis share their view on parenting. The research required a comprehensive literature search, partly to examine earlier research in the particular field but also to gather information on parenting. One focus group interview and three semi structured interviews were used to gather relevant information. Informants were recruited from a project for individuals with neuropsychiatric disabilities.

AbstractThe purpose of this study is to illustrate Serbia?s democratic development on the basis of consolidate democratic perspective. Linz & Stepan´s five arenas (political, civil, economic, legal and bureaucratic) are required for the possibility to become a consolidate democracy. In order to fulfil the aim, I have chosen to focus on the political and civil arenas that are most central in the study of consolidate democracy.The purpose of this study is to process how far Serbia has come towards a consolidate democracy and which obstacles still remain in the transition.The questions in this study are:? What problems has Serbia faced since the democratic transition in the beginning of 1990?? What possibilities are there for Serbia to consolidate the democracy, with focus on the two key arenas of consolidation?By applying the theoretical framework to the data, I have been able to present answers and build up an analysis.

I samhället Glumslöv, som ligger i Skåne, har en ny typ av radhus byggts, som kallas för självuppvärmande hus, beroende på att det inte finns något konventionellt värmesystem i huset. Det traditionella uppvärmningssystemet har istället ersatts med en luft/luft-värmeväxlare i kombination med ett värmebatteri om 900 W och extra välisolerade konstruktioner. Idag finns det bara en- och tvåplanshus som fungerar som självuppvärmande bostäder och i takt med att det byggs många nya flerbostadshus i landet, så kommer också behovet att försöka minimera energikostnaderna att öka. I vårt arbete har vi för första gången testat självuppvärmande konstruktioner för ett fyravåningshus. Husen har designats för ett projekt i Malmö som kallas Hammars park. Parken ligger i Sibbarp, som är ett område beläget i Limhamn precis vid Öresundsbrofästet. Området består av sammanlagt 21 hus med totalt 240 lägenheter. Husen har konstruerats och dimensionerats för att huset ska ha ett bra inneklimat och klara av en lång tidsperiod med ett minimum av underhåll. Enligt vår IDA databeräkning kommer värmeenergibehovet i en tvårumslägenhet att vara ca 350 kWh/år, och för en fyrarumslägenhet 950 kWh/år.

Teenagers are the group that spends most money on clothing. When choosing clothes, the so called internal and external signals could affect the perceived quality of the teenagers. The external signals are for example price, brand and place of purchase while the internal signals are the physical composition of the product as for example garment and size. The perceived quality is the attributes that the teenagers perceive that the specific article of clothing has. Today?s marketing, within the fashion line, is mostly to present the design of the product and aim the marketing for curtain segments and to keep a distance to others that are not within the segment group.

This thesis describes the redesign ofequipment designed for drying bags thatis used in Fresenius Kabis´manufacturing of their nutritionmedicine in Uppsala. The need of thistask arise during the start of thedevelopment of a new packaging line werethis equipment were meant to be used. Anevaluation of the bagdryers capacity andcapability was necessary.The work started with gathering ofinformation from suppliers of the usedcomponents and from the responsibleengineers for this equipment. Aneducation to learn how the equipmentworked and how to operate it were taken.That was followed by the creation of astudy plan were the tests were plannedto test different parameters effect onthe drying result and to see if thebagdryer managed to handle the bags ofthe correct format in the pace that theequipment should be designed for.The test results detected a need ofdesigning a unit with a function thatholds the bags in place while passingthrough the dryer in order to attainhigh quality results. The results werelater used for optimization of thedesign.

The purpose of this degree-project was to investigate the possibilities for primary air preheating into the two smallest waste incineration boilers of Halmstad Energy and Environment. The investigation is a pre-study which has the primary goal to evaluate technical and financial offers from companies that manufacture primary air preheater, and investigate if it is technically and financially profitable to do a purchase on primary air preheaters in the future.In the pre-study it is proposed that it is most efficient to have individual primary air preheater, one for each incineration boiler and the primary air are also proposed to be preheated by hot water in the pre-study. Further in the pre-study it is proposed that the heat-exchanger should have plain tubes instead of finned tubes, to avoid getting dirty fast. The space in the boiler-room is limited, and therefore the major problem was to fit in the primary air preheaters into the boiler-room. By comparing the different offers from the companies, the result in the pre-study shows that the offer from the company C.A.
