Optisk undersökning av dieselsprayer från en höghastighetsroterande insprutare

There have been changes in Earth?s climate system on both global and regional scale since the pre-industrial era and some of these changes are due to human activities such as the combustion of fossil fuels. This calls for the development of engines with a higher efficiency and less harmful emissions. One interesting concept is the Homogeneous Charge Compression Ignition (HCCI) engine, which has the advantages of potentially low emissions combined with high efficiency. However, HCCI with diesel fuel requires a relatively long fuel/air mixing time to ensure a "homogenous" charge.

Spelimmersion & död : En undersökning av hur spelupplevelse och immersion påverkas av döden i nätbaserade multiplayerspel

Immersion is a construct that measures how deeply engrossed a user is with any mediated situation. In the field of game design, immersion is a significant aspect of what makes a game enticing, and as such it is of pivotal importance to create and maintain it to keep the player's mind off the real world while inside the confines of a game framework. According to the GameFlow theory, it is one of seven key tenets of evaluating and implementing a successful game design. Yet, certain multiplayer online games are designed in a fashion that in some cases seem to break immersion, where the player is frequently put out of action, sometimes for minutes on end. In this study, using online questionnaires, we discover that players, despite claims otherwise, seem to be in several ways affected negatively by this breaking of immersion.

Analys och förbättringsförslag för riktkopplardesign

Ericsson develops a new stripline directional coupler. Its design is described in appendix B and differs from the directional couplers Ericsson uses in current products. The new directional coupler will be used for transmission power measurement in future UMTS 3G base stations.The most important parts of directional coupler theory are presented. It is necessary to study this theory to understand how the coupler works and how it should be designed to get good performance.Optimal directional coupler termination component values to get high directivity and broad directivity bandwidth have been investigated.The trim screws trim ranges have been studied.A simple analysis of serial production performance when termination component tolerances are taken into consideration has been done.The resistance components reactive (inductive/capacitive) characteristics at 2.14 GHz have been analyzed.The directivity performance limitations of the directional coupler, when Ericsson?s band pass filter is connected, are investigated.Design changes leading to better performance are proposed.

Tro och Vetenskap : Intelligent Design på Newsmill 2010-2012

Syftet med denna uppsats är att analysera debatten som tog plats på hemsida Newsmill åren 2010och 2012 om intelligent design. Fokusen i själva textanalysen är en argumentationsanalys somtillsammans med kritisk diskursanalys skall utröna och förstå den maktförskjutning som går attfinna inom diskursen. Den kritiska diskursanalysen är byggd på Norman Fairclough. Analysen ärordnad kronologiskt och innefattar tjugotre artiklar allt som allt.Fokus i själva analysen ligger i att utröna och förstå hur debattörerna ställer sig till religion ochvetenskap i deras argumentation kring intelligent design. Här går att finna hur religion ofta förs insom begrepp i relation till personers emotionella agerande och överlag blir religion en belastning fördebattörerna.

This group consisted of company managers and bank employees, all from the small town of Åtvidaberg in Sweden.The method used in the development process was Scrum. A total of three sprints were completed with user meetings at the end of every sprint.

Hållbara projekteringsverktyg : Från byggnadsinformationsmodell till simulering ? en utvärdering av Revit och Virtual Environment

This study examines the use of building modeling and energy simulations in the design process  of  a  building.  The  take-off  point  is  the  notion  of  energy  simulations  being needed early and throughout the building design process, and that the lack of energy simulations may be explained by the fact that they are time consuming and therefore often too expensive. A greater interoperability between software tools used by relevant disciplines,  such  as  the  architect  and  the  energy  specialist,  would  create  smoother workflows, which would reduce this cost and open up for more frequent and iterative energy  simulation  processes.  The  study  is  an  assessment  of  the  modeling  tool  Revit and  the  simulation  tool  Virtual  Environment  and  whether  they  can  create  smoother workflows, and make leeway for a more frequent use of energy simulations throughout the  design  process.  It  also  investigates  the  limitations  of  what  can  be  examined  by simulations in Virtual Environment. This will hopefully help clarify the future role of energy  simulations  in  design  processes.  The  method  is  a  trial  by  error  approach  of testing the two software tools by building and simulating a model. The results of these tests  show  that  the  workflow  is  not  optimal  (and  therefore  time  consuming)  for frequent  and  iterative simulations  throughout the  design  process,  but  it  also  reveals some  great  possibilities  of  what  can  be  performed  with  these  two  powerful  tools  at hand.  Further  development  with  regards  on  platform  independency  of  the  building information  model,  including  seamless  exporting  and  importing,  seems  necessary  to strengthen the future role of energy simulations..

Elektriskt system för detektion vid ballistiskt prov

The purpose of this thesis was to design an electrical system for use in a ballistic test at the Swedish National laboratory of forensic science (SKL). The detector unit would use four main parts: coilsystem, transmitter, reciever and indicator. The coilsystem would be based on a balanced system using three coils. One that creates a magneticfield and the other two will sense the differences when a metallobject is in the coilsystem. This report starts out by investigating possible solutions for this specific task followed by a description of the physics that the metaldetector use.

Läsflöde eller läsmöda? : Ett arbete om hur la?sning pa?verkas (och inte pa?verkas) av olika element pa? en webbplats fo?rstasida.

The purpose of this project was to find out how reading is affected, and not affected, by different elements on a start page. The site I was studied belongs to the magazine Fitness Magazine, and the current site has a problem. The editorial texts and articles don?t reach out to the visitors. The goal was to make a proposal for a new first page of the web site that highlights the texts and the reading.With the help of interviews, user testing and textual analysis, I studied if the texts were in itself that caused the problem or if it was the design.

Landskapsarkitektur och hållbar design : förhållningssätt, tillämpning och värdering

Hållbarhet är ett begrepp som varje landskapsarkitekt ofrånkomligen tvingas att förhålla sig till. Frågan för denna kandidatuppsats är på vilket sätt det görs. Målet är att undersöka landskapsarkitektens förhållande till och tillämpning av hållbarhet och hållbar design, för att på så sätt bidra till att lyfta en diskussion kring vilken roll landskapsarkitekten spelar inom arbetet för att skapa ett mer hållbart samhälle. Genom granskning och analys av litteratur samt genom en intervju ämnar uppsatsen svara på tre huvudsakliga frågeställningar: den första handlar om begreppet hållbarhet, om hur det uppstått och hur det används inom landskapsarkitekturen; den andra frågeställningen gäller tillämpningen av hållbar design; och den tredje rör värdering och analys av hållbar landskapsarkitektur. I uppsatsen undersöks och beskrivs både metoder för att uppnå hållbarhet, hållbarheten som färdig produkt, samt inställningen inom landskapsarkitekturen till hållbarhet och hållbar design i stort. Resultatet visar på ett komplicerat förhållande, ofta speglat i hållbarhetsbegreppets komplexitet, vilket också i stor utsträckning påverkar tillämpningen av hållbar design inom landskapsarkitekturen och metoder för värdering och analys av hållbarhet. Själva komplexiteten framträder genom uppsatsen som en drivande kraft och öppnar för en fortsatt diskussion kring både utmaningar och möjligheter med tillämpning av hållbar landskapsarkitektur i framtiden..

Evaluating six crop mixes used for game fields in southwest Sweden : biomass production, fallow deer preference and species diversity

Game fields are one way to divert animals away from sensitive areas, create shelter and forage, and also to increase the biological diversity. In this study I investigated how the plant composition in six different crop mixes used for game fields affected the biomass production, biomass consumption and biological diversity at the Koberg estate in southwestern Sweden. Six experimental fields were used and each field contained six plots, approximately 1500 m2 each, that was sown with a different crop mix. The crop mixes ranged from a pure grass mix (A), 70 % grass and 30 % leguminous plants (B), 53 % grass, 21 % leguminous plants and 26 % other herbs (C), 100 % leguminous plants (D) to the most complex mixes constituting of 91 % leguminous plants and 9 % other herbs (E) and 87 % leguminous plants and 13 % other herbs (F). The fields were cut weekly during the summer in 2010, to estimate weekly biomass production.

Seroprevalence of Rift Valley fever in domestic sheep and goats of Gaza province, Mozambique

Animal welfare is of increasing concern in present society. In commercial pig farming, animal welfare problems are common. One of the causes for these problems is the barren environment in which pigs are housed, which can cause oral manipulation of pen mates. Providing straw might be one solution to this problem. Another solution could be reached through genetic selection.
