Quality assurance for Scania engine componentsScania engines have become one of the world?s most renowned corporations in themanufacturing of engines. This is mostly due to the quality and performance thatScania have shown. However, this does not stop Scania from trying to achieve moresuccess in the fields of development and research to assure the quality of theirengines.The purpose of this thesis is to show how Scania ensures the quality of the enginecomponents, both those who made externally and internally at Scania, also inclusivethe manufacturing and assembly process.Three engine components were examined: D16 block engines, water pump andXP-Iinjectors. The study included the whole process from the step of supplying therow materials to the last step in production functional test.In this thesis an investigation of how other companies are working with qualityassurance was conducted.

This report summarize what have been done during the Master of Science Thesis that Klas Schjelderup has written for the company RANOTOR Utvecklings AB. The company is developing modern steam engines and this work should develop a machine to perform tests on a new type of piston seal that hopefully could be used in the future. The steam engines will be both volumetric and energy compact, around 1600hp/literof cylinder volume, and it will have a lot of practical applications.The new type of piston seal is hydrostatic lubricated which means that a fluid is separating two faces that normally is in contact. In this case pressurized water is used to separate the piston seal from the cylinder wall. RANOTOR have earlier formulated that at least the expander in the modern steam engine have to be oil-free, due to other components functionality in the closed water system.

The environmental requirements and laws on combustion engine emissions are very tough today andthey will become even more stringent in the future. To achieve these requirements there are highdemands on the control systems for these engines. An improved precision in the measurement of anengine's speed and position gives the electronic control system an even better timing when it comes tofuel injection and ignition. This makes the engine more fuel efficient, reducing the emissions. This thesisis part of a collaborative project between Hoerbiger Control Systems and subsidiaries.

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.

Today Internet is clogged up and packed with homepages and information from both private persons and commercial companies. This has led to a decreased availability for a company to be noticed. The most common tool for consumers to use while searching for products online is via search engines. But because of the nature of these, not all companies can have good placements. Our research question was, "How do small online-companies attract consumers to their website"? The purpose of this thesis is to identify how a company works through online-communications and how to attract consumers to their home page.

This review article presents the splicing process during messenger RNA maturation and how it is regulated by different Cis-regulatory RNA-sequence elements and splicing factors. A more detailed description of the process alternative splicing and its importance to the function of genes from the model organism Arabidopsis thaliana is also given. A single eukaryotic gene can by the process alternative splicing (AS) give rise to a number of functionally mature mRNA-molecules, which in turn encodes for structurally and/or functionally different proteins. During the course of evolution, the process alternative splicing has thus shown to be effective in increasing transcriptome and proteome diversity of most eukaryotic organisms. This suggests therefore that the dominant theory in molecular biology, a gene encodes for a protein, needs to be corrected.

This essay is written within my education for Technical Officer in the Swedish armed forces. The essay describes the alternative fuels that the Swedish armed forces can make use of if the supply of fossil fuels is insecure. The alternative fuels that are described and compared are; Synthetic diesel, Organic diesel, Methanol and Ethanol. The essay describes the process of producing the alternatives, the need for modification and the economics for each alternative. The alternatives are compared and assessed for their ability to secure the supply of fuel to the Swedish Armed Forces.

The purpose of this MSc thesis is to examine the retrieval effectiveness of two Web search engines with queries from the academic discipline of Classical Studies. The two search engines are chosen to represent two different types Google as a broad general search engine and Argos as a specialised search engine for the subject of Classical Studies. The search engines are compared for precision among the first twenty results returned for thirty queries. In order to avoid bias in the study, the queries are based on real users' information needs. Due to the subjective character of the concept of relevance, the study is performed with five different experiments with five different definitions of relevance.

ABSTRACTPurpose/aim: Are there any differences between how ?old? and ?young? groups within social movements in Sweden view (value) and use alternative and mainstream media?Material/method: The answer to the research problem is sought by conducting qualitative research interviews with representatives of four different groups: Alternativ Stad, Folkkampanjen mot Kärnkraft-Kärnvapen, Attac Sverige and Ingen Människa är Illegal. The theoretical framework consists of research on social movements, especially on their relation to media, and on alternative media.Main results: There exist some, but not great, differences between how ?old? and ?young? groups view and use mainstream and alternative media. The differences are relatively small when it comes to views on media and somewhat larger concerning media use.

This study's main objective was to identify adolescents participation in alternative sport activities and which kind of physical activity that was preferred by adolescents who didn't had any earlier experience of sport clubs. The study combined interviews and surveys with the purpose to get both adolescents and sport leaders perspective. A total of five interviews were performed and fifty-four surveys was collected. The results showed that adolescents already physical active were those who participated in alternative sport activities. Who participate in alternative sport activities can depend on habitus, comprehended capital forms and in which social field the sport activities exists..

The purpose with this thesis is to get a compilation of all the critical bolted joints of all enginesproduced at LV Motors. ABB LV Motors produces induction engines with seven shaft heights. Eachengine size exists several variants of components ex. standard shield and flange shield. Depending onwhich components the engine is equipped with arises various types of strains in the engine's parts,certain assembly ways are more favourable than other.The most critical parts in the engine from a mechanical point of view are the screw units betweenshield/stator, feet/stator and bearing cover/shield.
