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.

Rwanda is one of the poorest countries in the world and about 70-80 % of the population lives in rural areas. The land is strongly affected by land erosion which makes it difficult for the agriculture and food production. Agroforestry is a system where tree plantation is combined with livestock- and crop production. The system provides soil fertilization and binds the soil together. Some of the trees used in agroforestry systems are also used as fodder.

The Annexin-V/propidium iodide (AV/PI) assay detects early membrane changes in spermatozoa and viability using flow cytometry. It is an objective method that evaluates a much larger number of single spermatozoa compared with the usual estimation of motility, the most commonly used method for routine sperm evaluation. In the present study four ejaculates from four stallions were used in a split-sample design to investigate whether and how the number of intact spermatozoa is affected over time and after incubation at different temperatures, either those recorded during shipment of stallion semen for AI (9 or 5°C) or room temperature (20°C). The Annexin-V results did not reflect the motility results that were monitored in parallel. While motility decreased over time, the number of spermatozoa with intact membranes (viable) remained unchanged for at least 21 hours following a short period of initial instability.

The Swedish stock-market gives investors an opportunity to benefit from the global growth while financing companies invests and contributes to a socio-economic development. Parallel to the ownership of the funds also follows a responsibility as companies in the funds affect society and the environment. The growth of savings in funds, combined with an increased focus on sustainability has developed SRI (socially responsible investment). Therefore it is interesting to examine whether responsibility is an exception, which only concerns SRI-funds or a general principle, which includes the whole Swedish stock-market.The results of the survey makes it clear that all the Swedish major banks actively works to integrate sustainability within the respective bank's business to achieve a more sustainable financial system. Thus concludes the investigation that responsible investments are a general principle on the Swedish mutual stock-market.How responsibility is integrated in fund management differ between the banks.

Image indexing research today is either conducted on a visual attribute level or on a higher semantic level, forming a semantic gap between the two. There is much to gain if research progress from the two fields is combined. Image retrieval using access points in both visual and semantic significations could improve retrieval and bridge the gap. In social media today, images are often the primary communication agent and the number of images on the web is increasing in an uncontrolled way. New and efficient ways to index and retrieve the images are needed.The purpose of this study is to examine if emotions could be a semantic access point for image retrieval and if folksonomy indexing is useful when searching for images that represent emotions.

The aim of this paper is to investigate the subject matter of visual communication in presentation brochures of two Swedish regions: Region Halland and Region Dalarna. My focuses are the following questions: what is the aim of the brochures and in what ways does the visual material relate to that aim? How can strategic communication be defined through a visual perspective and in what ways is it useful in the context of presentation brochures of the regions? What sort of communicational functions are specific for the visual material in relation to the written language of the brochures? Lead by these questions, I start by analyzing the brochures through a textual analysis and a social semiotic approach. The result shows that the aim seems to be both political and commercial, but that the visual elements relate more strongly to the commercial aim than to the political aim by the way they strive to present a positive image of the region. The visual elements work in strategic ways that I define as visual strategies.

 We have chosen to write our thesis within a transport company. The work was carried out at DHL activities in Uppsala. DHL is one of the leading transport companies worldwide. Our interest lies in more efficient and advanced transportation and terminals, as globalization and new trends require effective solutions.The aim of our work is to explain the need for information technology applications in road haulage and associated terminal operations. Furthermore, we analyses terminal and applied information technology.

There are several methods avaliable to find areas of interest, but most fail at detecting such areas in cluttered scenes. In this paper two methods will be presented and tested in a qualitative perspective. The first is the darg operator, which is used to detect three dimensional convex or concave objects by calculating the derivative of the argument of the gradient in one direction of four rotated versions. The four versions are thereafter added together in their original orientation. A multi scale version is recommended to avoid the problem that the standard deviation of the Gaussians, combined with the derivatives, controls the scale of the object, which is detected.

Projektet har genomförts i samarbete med Lokalförvaltningen, Göteborgs Stad.Eftersom behovet av lokaler i en stad förändras över tid efterfrågas en byggnad som kan användas till flera olika ändamål under dess bruksperiod. Ombyggnation av befintliga byggnader kan bli kostsamma och tidskrävande eftersom bärande komponenter eller fasta installationer ofta måste flyttas eller bytas ut. En flexibel byggnad som redan vid uppförandet förbereds för ombyggnation kan enkelt anpassas och användas till flera olika verksamheter. Att bygga mer effektivt och flexibelt minskar kostnader och bidrar till ett mer hållbart byggande. Syftet med arbetet var att ta fram en byggnad som genom enklare omställningsarbeten i byggnadens invändiga utseende kan fungera för tre olika verksamheter.

Plant Protection Products (PPP) used in the horticulture industry can be both chemical and biological. They are used for weeds (herbicides), insects (insecticides), and fungi (fungicides) and as growth retarders.Many horticulture workers get in touch with plants, treated with PPPs and many of these don?t use any protective equipment.The aim of this project is to illustrate the work environment hazards for staff working with greenhouse pot plants, after they have been sprayed.The method used was observations of the operations for packing plants. I studied the operations and took notes of how operations were performed and what protective equipment they used. I also took photos and asked questions.A literature study completed the observations.

Purpose: The purpose of this study is to present an overview of the Swedish listed companies and their compliance with the Code and its normative rules for independent decision-making. Methodology: The authors have read and delved into the Swedish Code of Corporate Governance. The authors have chosen to study the enforcement of the code based on independent bracing guidelines. The study was conducted through a combined quantitative and qualitative approach. The study is based on primary data collected in the form of companies' corporate governance reports, which have been supplemented by structured interviews.Frame of reference: Swedish ownership structure and concentrated ownership, self regulation and normative guidelines, institutional theory and earlier research on this topic.Empirical foundations: A comparison of the selected companies has been based on the independence rules of the Swedish Code of Corporate Governance. A specific company has been presented with the company's application of the code, interviews have also been done with this company to increase the understanding of the empirical basis further.Conclusions: There are several flaws with the code and how it is applied today.

The aim with this paper is to investigate how the Social Democratic Party (SAP) deals with the question of economic migrants, or more specifically how the problem is represented by the Social Democratic Party, and how this representation has developed over time. The SAP's theory became recently contested by a competing theory that was caused by the predicted future demographic development in Sweden, combined with the EU's eastern expansion. The first factor contributed to the re-write of the theory, to a theory that saw economic migrants as a solution instead of a problem, in direct contrast to SAP's theory. The second factor was a direct threat to SAP's labour immigration policy. This leads to my second question, how did SAP respond to this pressure?The answers to these questions are achieved by using discourse analysis by applying a problem oriented theory on empirical material, constituting propositions, articles in mass media and parliamentary debates.

The purpose of this study was to explore the connection between substance abuse and completed/attempted suicide. Central questions were who the substance abusers who commit suicidal actions were. The study also tries to find out which factors that contributes to this behaviour and why it is so common amongst substance abusers. All from the point of view of three scientist and three persons working with treatment of addicts who were interviewed. The results of these interviews were analysed on an individual level with a psychological theory.

The main purpose of this Master's thesis is to investigate the new librarians' experiences and skills in the context of their present work situation and the ongoing debate about the librarian's professional identity and status. Further, the authors wanted to find out whether the new librarians' experiences and knowledge developed throughout their education correspond to the requirements of the employers. Finally, they try to assess theimpact of the "academization" of the library schools on the status of the profession. The data consist of an opinion poll. The investigation is based on questionnaires distributed as a web survey.

Title: ?The letters jump?- to struggle with decoding and still understand what you are reading.Author: Maria EkUniversity of UmeåDepartment of EducationSupervisor: Asbjörg WestumExaminer: Fredrik KarlssonKeywords: Poor readers, Structured text talks, Reading strategies, Reading comprehension, Commitment and Motivation.During the past decades, Swedish studies show that reading comprehension and skills in reading strategies have decreased. In secondary school for individuals with learning disabilities there has been a focus on care-taking rather than on comprehension in general, and on reading comprehension in particular.The purpose of this study was to investigate whether Reciprocal Teaching would increase reading comprehension and motivation among upper secondary school for individuals with learning disabilities. The study presents how three 17-year-old pupils and their teacher, discussed expository fact texts during twelve lessons using the reciprocal method combined with power point-presentations to get the students to read more actively with interferences and reflections. The ambition was to make the structured text talks as interesting as possible with texts easy to read, technical aids, structure to make the students feel security when reading and to get committed pupils with an increased interest in reading.The results show an increase in motivation in reading, and the students were more prone to take an active part in discussions..
