The work covered in this report includes a literature study of the diesel dual fuel technology(hereinafter referred to as DDF). The literature study covers earlier work that has been doneregarding the use of compressed natural gas (CNG) and diesel in a DDF system. Moreover a onecylinder research diesel engine was fitted with a CNG fuel system for experimental testing. Theinstallation of the engine and the test cell is described. Results from the tests are presentedcovering emissions, heat release and pressure traces from the DDF-concept.During the literature study it was found that most research was related to heavy duty dieselengines.

Föreliggande uppsats utgår från ett potentiellt problem för Försvarsmakten att i det nyligen införda tvåbefälssystemet omhänderta den högskolemässigt utbildade officeren som sannolikt generellt innehar en högre utbildningsnivå och mer uttalad karriärambition än de äldre yrkesofficerarna från det tidigare enbefälssystemet NBO.Uppsatsens syfte är att tydliggöra vilka förutsättningar på arbetsplatsen som gäller för tvåbefälsystemets högskolemässigt utbildade officerare vid officersprogrammet ur ett anställningsbarhetsperspektiv. Anställningsbarhetsbegreppet kommer att utgöra det redskap som jag applicerar på det avgränsade empiriska materialet för att se vilka förutsättningar, som gäller på arbetsplatsen i jämförelse med kraven i examensbeskrivningen för de högskolemässigt utbildade officerarna då de tagit examen sommaren 2010. Är de anställningsbara? Genom en dokumentgranskning tolkas och jämförs de dokument som ligger till grund för officersutbildningen och de strategiska styrdokument som definierar Försvarsmaktens verksamhet.Resultatet visar utifrån ett anställningsbarhetsperspektiv att Försvarsmaktens dokument och officersprogrammets utbildningsplan samt examensbeskrivning i stort sett stämmer väl överens vilket borgar för en hög anställningsbarhet hos officeren..

A webpage can be perfectly usable but if users are unable to find the webpage it will remain unused. Nine out of ten Swedes use a search engine and the most popular one is Google, amongst other search engines. In this report I seek to answer which ranking factors that should be included in an SEO-audit of an existing webpage and also how to optimize a webpage for search engines. Applying the method heuristic evaluation normally used to discover usability issues in an existing interface, on TT News Agency?s campaign site I found issues having a negative impact on the visibility in Search Engines Page Results.

Biogas is a gaseous fuel, rich in methane, produced through a biological route in an anaerobic digester. A gas engine generates combined heat and power, which can be used at the farm to reduce energy cost. The process also generates a digestate, with better utilization of nutrient compared to cattle manure. The aim of this study is to analyze the profitability of a farm-scale biogas plant for combined heat and power (CHP) at Wapnö. Wapnö is an agriculture company located in the southern part of Sweden.

The ?civilized? world is in need of fossil fuel in order to function. Hybricon AB is a company in Umeå that is developing a technology that hopefully can reduce parts of this need. They are currently testing their two electrical busses (with Hybrid backup) in city traffic on the roads of Umeå in cooperation with the county of Umeå.                               The busses are originally diesel-busses, but the diesel motor has been replaced with two electrical hub-motors with a power of 145 kW each that are powered by batteries.The batteries are charged at the end station after each route. In case the batteries should run low on capacity during driving, they can be recharged by the so called genset.

The purpose of this study was to analyze the level of the uniform way of interpretation from the Swedish asylum officers at the Swedish Migration Board, of asylum investigations for asylum seekers who claim sexual orientation as reason of refuge. The interviews with the officers were analyzed in relation to the policy document with investigation- guidelines and methodology.The results of the study showed that there was a uniform way to conduct asylum investigations and interpret the policy document, this despite that the document was found to be ambiguous in certain aspects. The uniform interpretation of the asylum officers was explained by the knowledge and understanding that exists within institutional organizations. This because the asylum officers at the Swedish Migration Board might have similar experience, knowledge and also the demands related to asylum investigations.The uniform interpretation demonstrated a strong similar common understanding of investigative work within the agency. This suggests a certainty that the investigations are carried out in a similar way regardless of which asylum officer within the institution conducting the investigation which indicates a well-functioning ?rule of law? for the asylum seekers. .

The municipality, of Gatukontoret in Local government of Borås has in the long run, a required need to look after the current heating devices (the gas production plant) in sewage treatment plant, called Gässlösa. The practical work of the examination is about, trying to find a better way to take care of the current heat recovery. That may be one way or another, rather easy to implement in the existent construction.Through the work to increase the efficiency of the gas engine, implement of some external cooling system by heating exchange device. That gives an opportunity to heat (primary) the digester, (but even all internal public areas) with its own superfluous heating.The report shows that if the management group may invest 422 704 crown to implement a heat exchanging device, it gives more space to reduce the need to buy expensive external energy. Gatukontoret´s pay off time, for buying machines, is 20 years, with reservation to calculate with 4 percent internal interest, leads to the yearly mount of 31103 crowns.If Gässlösa increases the gas engine time in (effective) duty approximately (correspondingly) 48 hours a month the entire investment will generate a profit in January in year seven after the implementations.

Scania is among the leading companies in the heavy vehicle industry. Scania also assemble engines for their trucks and buses, as well as to external marine and industrial applications. Wrongly assembled parts leads to quality problems, which makes it important to secure that the assembly is correct. To do this Design For Assembly (DFA) is used to describe how parts should become easier to assemble. Scania?s production unit for engine assembly has had a working method for DFA in the shape of a checklist, which is not used.

Urban planning is not only a matter of architectural trends; it is first and foremost political. This thesis seeks to understand the links between political ideas and visions for the city and the physical structure of the city. The study aims to construct a model to help understand these links, a helpful tool in analysing a city, focusing on the one hand at the physical structure of what I call "The City as a Welfare Provider" and on the other hand at "The City as a Growth Engine". It also sets out to test this model in an empirical study of Stockholm and the soon-to-be built district of Norra Station in the same city.The analysis shows that Stockholm has ambitions to be a welfare provider to its citizens, but have also adopted to a discourse of interurban competition which stresses the importance for the city to enhance economical growth. What is interesting is that the physical structures promoted in the planning documents of Stockholm are nearly exclusively those associated with the model of "The City as a Growth Engine"..

The aim of this thesis was to study librarians approach upon reference questions and available resources and also to find out if there is any connection between the nature of the reference question and the choice of resource. The purpose was also to give a deeper understanding of the reference work. Nine librarians were given ten reference questions and their reference work was tape recorded. The study was completed with seven interviews sent by email. Some of the reflections were translated under the headlines of form, subject, time, language and availability.

Den svenska Försvarsmakten har de senaste åren omorganiserats från ett invasionsförsvar till ett insatsförsvar. Genom detta har bilden och kraven på officeren förändrats, därtill också officersutbildningen.År 2007 introducerades Specialistofficersutbildningen och fr.o.m. januari 2009 använder sig Sverige av ett tvåbefälssystem baserat på internationell praxis. De två befälskategorierna benämns specialistofficer och officer med taktisk- operativ inriktning.Med uppsatsen avsåg författaren analysera framtagandet av specialistofficersutbildningen samt analysera hur tvåbefälssystemet kan komma att påverka Försvarsmakten som organisation. Detta genomfördes genom intervjuer med avgränsning till ett kompani där två av sergeanterna som genomfört Specialistofficersutbildningen 2007-2008 tjänstgjort och berörda befäl i kompaniorganisationen.

The purpose of this study was to understand what the professionals experiences are of stressed youth. We did a qualitative study with interviewing three school nurses, one welfare officer and two recreation leaders. Research is saying that stress is increasing among the youth and that girls are more stressed than boys. It also says that medium is a big consequent for that (ex. Brun M.

Syftet med detta examensarbete är att vidareutveckla glasfiberbalkar så de kan användas som mellanbjälklag i småhus. Förebilden var ett ?Delta Deck? som utvecklats av Altakor Group och används i brokonstruktioner. Denna profil har vi sedan modifierat och optimerat för bruk i småhus. Den största skillnaden är att vi valt att inte använda den så kallade ?snap-fit?-tekniken.

The purpose of this Master?s thesis is to evaluate three general query-based web search engines. The search engines chosen are Google, Yahoo! and Live Search. The topics, which where transformed into twenty queries, are based on real users? information needs, taken from an ask-a-question service.

This thesis considers the problems associated with searches in insufficiently geographically tagged data. The thesis was carried out at Booli Search Technologies AB, a company developing a search engine for the Swedish real estate market.The aim of the thesis is to identify some areas of possible improvements of the company?s existing technical platform, perform a benchmarking among similar services, suggest possible solutions and lastly, build a prototype from one of the suggested solutions.The thesis starts out with defining the problems that the search engine faces: some areas are not possible to perform searches on, the users are not presented with the full search result that they expect, some results are placed incorrectly on the map associated with the search results and results are also not described with enough geographical information. These problems are due to the fact that the data retrieved at the indexing stage in the company?s information retrieval process are insufficient and incomplete.As a result of a benchmarking process and after discussing the results, severalinteresting solutions were identified.
