Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.

The purpose of this study was to make a survey of a larger company in Sweden to analyze if it complied to the stipulated Systematic Work Environment Management rules in Sweden. The company chosen was Hennes & Mauritz. The key question was to see if the company was examining and judging the risks, developing handling plans and if they were making yearly follow ups so that problems could be attended to. Further, I also wanted to examine if there was lack of competence within different departments as well as give some substantiate proposals on educations in Systematic Work Environment Management. The method used to investigate this was interviews and observations on how the Systematic Work Environment Management was handled in the company.

This thesis will describe the redesign of the manure fork SverigeGrepen. The productis available for purchase in Scandinavia and and parts of the rest of Europe.The product is available in stores but the companys goal is to start distribute it overthe internet. A problem today with a purchase over the internet is that the costumerhas to pay a high shipping-fee due to the products unique form. The long handlecontributes to the high shipping-fee which makes it hard to attract costumers topurchase the product online. Deficiencies have been found at the manure forks basketand needs to be examined.

Hållbarhetsfrågan i klädbranschen är fortfarande i en utvecklingsfas och tidigare forskning visar att det finns ett flertal möjliga faktorer som är bidragande till att kunder i dagsläget inte konsumerar på ett sätt som går i linje med deras värderingar. Syftet är att utforska hur kunder kan engageras att främja hållbarhetsaspekten vid klädinköp. För att uppfylla syftet utformas två forskningsfrågor. Metoden är en flerfaldig strategi med ett huvudsakligt kvalitativt fokus. Angreppssättet är abduktivt genom kombination av deduktion och induktion. Studien består av en kvantitativ enkätundersökning följt av kvalitativa semistrukturerade intervjuer.

VikingGenetics is one of the world's largest breeding companies. 2008 was launched two new products, X-Vik and GenVik. Now VikingGenetics want to get information about the effects of the marketing. We have investigated the differences in knowledge and use of the products between different livestock associations, size of herd and farmers' breeding interests. The method used was by sending out a questionnaire by mail.

When a combined heat and power plant produces heat and power it often faces a deficit of heat load during the summer or other periods of time. This heat is often unnecessarily cooled away or the power production has to be reduced or shut off. If it is possible to store heat from periods with low heat demand to periods with high heat demand one can get many benefits. Among these benefits are: increased power production, decreased operation with partial load, uniformly distributed load.To be able to store heat in situations like this long-term thermal heat storages are needed. In this thesis five different types of stores are presented: rock cavern storage, tank storage, pit water storage, borehole storage and aquifer storage.

This essay is about the history of the Swedish board game-industry from the 1970?s to today. The essay focuses on the companies in the business and how they change during this period and about the causes of this change. This essay aims both at accurately describing the development of the industry as well as asking the question of what influence factors from outside of the industry have upon the change during this period of time. The material used in this essay is mainly extracts from interviews with people who have been working in the industry during the period, as well as literature on the subject and product-catalogues from certain years in the time-frame.From this material I have outlined the basic history of the industry.

The purpose of this thesis is to examine whether parents that obtain long-term maintenance support in Enköping, consider the support as adequate when trying to meet their children's basic needs. The thesis also intends to investigate whether parents experience that their children, because they receive income support, have been socially excluded or stigmatized in their daily lives because of the family?s maintenance support. Further, the thesis aims to examine if there are any discrepancies in the above mentioned issue in relation to how long the parents have received maintenance support. Theoretical starting points used in this thesis mainly consist of the child perspective, social exclusion and the stigmatization theory.

Statistics Sweden is an administrative agency that delimits built-up areas and produces statistics regarding them. The statistics provide information about the area of the built-up areas, their population number, number of gainfully employees working in the built-up areas, and of buildings. Now Statistics Sweden wishes to extend such statistics by producing a measure regarding how well developed the service is in each built-up area.This study is a contribution to this statistical improvement work and the purpose is to ? by employing geographical information systems and cluster analysis ? classify the Swedish built-up areas according to 1) service width and 2) service degree. A particular built-up area has a high service width if it has many different service functions, such as pharmacies, schools and grocery stores.

The knowledge development regarding in-store marketing has shown that influencing a consumer in a store setting is a powerful tool to change the consumer?s buying patterns. However, the store as a marketing channel lacks, in many ways, conducted academic research and according to marketing theory investments into in-store marketing tend to be taken without advanced marketing consideration. As a consequence, we have chosen to generate new insights into the field of in-store marketing by studying in-store demonstrations both from a behavioral and a mental dimension. Furthermore, we have also chosen to study how different consumers with different degree of loyalty and buying patterns are influenced by an in-store demonstration.This study aimed to obtain a better understanding of in-store demonstrations through breaking down the demonstration into its core elements and from these elements construct different types of demonstrations.

Uppsatsen redogör för tre svenska klädföretags miljöredovisningar och hur dessa uppfyller de kvalitativa egenskaperna: begriplighet, relevans, tillförlitlighet och jämförbarhet. Dessa kvalitativa egenskaper ska enligt det internationella redovisningsorganet IASBs föreställningsram vara uppfyllda i de finansiella rapporterna som företagen lämnar. De tre klädföretag som vi har valt att undersöka har offentliggjort frivilliga miljöredovisningar. I dagsläget finns det inga lagkrav på hur frivilliga miljöredovisningar ska presenteras, däremot finns det olika rekommendationer. Vi menar att IASBs fyra kvalitativa egenskaper kan appliceras på frivilliga miljöredovisningar i syfte att säkerställa ett visst mått av kvalitet.

As a consumer, you can use cards for payment more or less everywhere you go, however, it is not certain that the card can be used for all purchases. When a customer pays with card there arises a card transaction fee charged to the merchant. This is a big problem for businesses where transactions with small amounts are a large portion of sales. An observation at the beginning of this study showed that seemingly similar merchants have chosen to solve this problem in different ways. Some merchant?s refuses card purchases below a certain amount, while others accept card with any purchase.

AbstractThis bachelor thesis has been assigned by the company ACG Nyström, Borås. ACG Nyström is working in cooperation with a Swiss company named Jentschmann AG. Jentschmann is a manufacturer of ultra sonic welding machines which ACG Nyström is marketing in Scandinavia and the Baltic States. On behalf of Jentschmann AG the company has the aim to introduce the ultra sonic welding technique to new companies.The aim of this thesis is to compare traditional sewing machines with ultra sonic welding machines within two textile areas, protective clothing and outdoor living.Two investigative questions have been formulated for this purpose: what are the differences between a sewing machine and an ultra sonic welding machine? Is it possible to replace the sewing technology with ultra sonic welding? These stand as guidance for this paper.To gather knowledge interviews, literature studies, and tests on two different ultra sonic welding machines were performed.

Background: Energy drinks have been found in everyday-stores since 1997 and their popularity have increased over time. Consumtion of energy drinks takes place because of their ability to increase concentration and to decrease fatigue but also because of the popularity the drinks have got. Target groups for these stimulating beverages are adolescents and young adults. Energy drinks contain caffeine, taurine, glucuronolacton, carbohydrates and B-vitamins and voices have been raised about the eligibility for young people to ingest large quantities of these kinds of substances. Because of the properties of these substances it has become popular to mix energy drinks and alcoholic beverages to make up for the negative effects of alcohol and to be able to drink larger quantaties.Aim: The aim of this literature work was to investigate cognitive effects of the combination of caffeine in terms of energy drinks and alcohol and to determine if these effects could be harmful.Method: This literature work is based on five scientific articles retrieved from PubMed.

Studien görs i samarbete med ett mindre svenskt modeföretag som i stor utsträckning arbetar med draperade produkter. Överföringen från draperat plagg till ett reproducerbart platt mönster består av ett omfattande arbete med uppsömnad av ett stort antal provplagg. Därför finns ett stort intresse för att resurseffektivisera denna process. I studien undersöks CAD och 3D-simulering som komplement vid framtagningen av produktionsanpassade mönster i syfte att återskapa en specifik draperat form. Som utgångsläge för studien finns ett plagg som draperats på docka av den externa handledaren och designer på företaget.
