The purpose of this thesis for Sapa Heat Transfer is to examine a furnace in which aluminium is pre-heated before hot rolling. The project is modeled in a computer environment in which the air flow in the furnace and the heat transfer to the aluminium solids are included. The computer environment and its governing equations, as well as boundary conditions and generalizations, are presented and explained.The simulations are based on two models. The first model has an asymmetric solid placement, which is how it looks in today's ovens. It is validated against collected data.

Intranet is today a common technical groupware to communicate in many organisations. People can interact through the Intranet and communicate within the organization and get relevant information according to their workplace. It can be difficult to get everybody to use the Intranet as an information- and communication tool. This causes problems when people want to reach out with information. With these thoughts we entered our work at Luftfartsverket at Arlanda airport.

Since studies points out declining interest in science among students in Swedish schools, I have in this paper chosen to examine how some students at the Social Science Programme are experiencing the lessons in Natural Science and how to make lessons more interesting according to these students.The purpose of this study was to gain a greater understanding of how teachers would develop new perspectives and tools to make lessons in Natural Science more interesting. I also wanted to investigate whether an intercultural perspective could be a possible tool to increase students? interest and motivation.As a theoretical framework, I have assumed Vygotskij's sociocultural perspective, Habermas's theory of deliberative conversations and an intercultural perspective. Through a qualitative approach, I conducted interviews with students and teachers. The main results showed that students felt that natural Science lessons were too theoretical and undemocratic and that they wanted to have more student interactions, such as discussions and group works.

European cities of today are under the challenge to find ways to stay competitive and flourish in a rapidly changing world, where the old patterns of centrality and periphery not necessarily holds true. New and improved communication networks, a changed political geography in Europe, and the globalisation of not only the financial and industrial markets but also to a certain extent the globalisation of people, have all led to great challenges for cities and regions.In a changed spatial reality the classic monocentric models are challenged by newer models of urbanisation. The polycentric urban region is one such model which has been used to describe urban regions like the Randstad in the Netherlands and the Rhein-Ruhr region in Germany. Regions which lack the single dominant central city of the monocentric models of old, and instead shows a high degree of more equal-sized and sometimes more specialised cities in regional cooperation. The polycentric urban region is in that aspect a possible model for how other urbanised regions in Europe may act to be able to position themselves as attractive urban regions and regional hubs in the European urban network.Polycentric urban regions are not a universal solution, though.

Det finns flera olika metoder och tekniker för tredimensionell rendering, alla med olika för- och nackdelar som lämpar sig för olika applikationer. Voxelbaserad rendering har använts flitigt inom vetenskapliga områden, främst inom det medicinska för visualisering av volymetrisk data. Tekniken används nu inom flera olika områden för tredimensionell rendering, t.ex. i datorspel, i matematiska applikationer och vid geologisk rekonstruktion. I den här rapporten kommer voxelbaserad rendering med Marching Cubes-algoritmen undersökas för att se hur den lämpar sig för realtidsapplikationer. Området behandlas dels teoretiskt, men även praktiskt då en implementering av Marching Cubes gjordes för att genomföra några tester för att se hur prestandan påverkades. Av testerna framkom det tydligt att algoritmen lämpar sig väl för realtidsapplikationer och dagens grafikkort.

Spel idag kräver en enorm mängd arbetstimmar för att skapas, därför behövs alltid sätt att spara tid och automatisera processer. Algoritmer för polygoniseringen av skalärfält, som Marching Cubes, har under de senaste åren blivit ett allt vanligare tillvägagångssätt för att automatiskt generera terräng. Scenkomplexiteten och kraven för visuell kvalitet i dagens spel ökar ständigt. Därmed kommer också kravet för prestandaeffektiva renderingsmetoder. Deferred rendering är en renderingsmetod som kan hantera scener med stora mängder ljuskällor och hög scenkomplexitet samtidigt. För att undersöka integreringen mellan procedurellt skapad terräng och en deferred rendering pipeline, skapades en applikation i DirectX 11 för att undersöka implementeringen och potentiella optimeringar av denna integration..

This thesis deals with one of the main questions within information science: The question about controlled and uncontrolled vocabulary and which of the two that are most effective when it comes to retrieve relevant information from electronic databases. The method used here is literature studies. I have described and examined five empirical studies which has been done in purpose to compare the effectiveness in retrieval with controlled and uncontrolled vocabulary, in the way they are used in retrieval of information in databases. The studies I have examined have also used recall and precision as a value to measure the effectiveness of retrieval. The studies which I have chosen is also limited to deal only with studies that have been done in bibliographic databases.

I Sverige och utomlands har man på senare tid sett framväxten av ett nätverk av s.k. Science Centers (SC). Dessa SC har som viktigaste syfte att öka besökarnas naturvetenskapliga intresse. När det gäller elever från högstadiets senare år kan detta ökade intresse för naturvetenskap t ex visa sig i form av en ökad benägenhet hos eleverna att söka sig till ett naturvetenskapligt inriktat gymnasieprogram.Vi har utvecklat och använt en enkät-baserad metod för att undersöka den påverkan på elevers intresse för naturvetenskap som ett besök på SC har. Enkäten är lämplig att användas för elever från grundskolans senare årskurser.

This report is a bachelor thesis presented at the department of Computer Science andEngineering at Chalmers University of Technology. The aim for the project is to find a simplemethod to measure and display physical quantities in a three dimensional room.The report describes a method to construct a system for measuring differentphysical quantities via sensors. The system must be built in a modular and expandable way tobe adaptable to different tasks.The system explained in the report consists of two parts;A physical scanner with moveable probes for carrying sensors and a microcontroller forcontrolling the probes and communicating with the next part.An application written in Java for storing the measured values and presenting them in a lucidperspective.It is possible to construct the scanner with different designs and circuitry, with multiplexers andflip-flops, to ensure that an unspecified number of probes can be added to the system and thatthey can be operated simultaneously.The Java application is written in a modular way, using a design pattern that separates eachindividual part of the application. It contains exceptions and interfaces that ensure a safe andexpandable application..

Detta kandidatarbete fokuserar på att undersöka aspekter som kan förstärka en användares upplevelse inom digitala spel. De aspekter som vi valt att fokusera på är användandet av Oculus Rift och Motion Capture då de tar upp viktiga punkter som Virtual Reality, närvaro och inlevelse i spel. Vi valde även att fokusera vår produktion mot skräckgenren då detta är ett område vi båda har stor passion för i diverse media. I vårt arbete har vi fått fram en hypotes om att spel som fokuserar på att lämna karaktären i ett tomt skal (ingen personlighet), lämnar en större chans för inlevelse hos spelaren då användarens egna känslor speglas på karaktären. Användandet av Oculus Rift och realistiska röresler via Motion Capture har en tendens att även stärka detta..

This study investigated how banner ads, depending on its quality and placement,can capture a user's attention while searching for editorial content in an online newspaper. Furthermore, the user's search strategy was also studied to see whether it varied depending on the placement of an ad. An experiment was conducted where 20 subjects searched for articles in a Swedish online newspaper while their eye ovement was recorded with a headmounted eye?tracker. In each search task the online newspaper contained either a low quality ad or a high quality ad.

Most often when developing a new system there is a need get a functioning testtool up and running. Including time, cost and resources the solution isn?t always obvious, developing your own or buy one ?of the shelf?. The purpose of this thesis is to study how a general testtool for executing functional tests should be designed to be reusable, be based on recognized knowledge and be able to fast and simple be customized for different types of systems. Key functions from the litterature is presented and used in the design of a testtool prototype.

A film can attract all kinds of emotions and moods of the audience through its audiovisual communications and cinematic expression, in which music plays a significant role in both understanding and interpretation of film content.It is interesting to explore the musical significance and the emotional aspect of the film out of a media and communications perspective and visual communications perspective because it?s a subject that belongs to the communications of scientific discipline as film is a media text which is working both as communicative and as audio-visual medium with its expressive aspects.The purpose of this bachelor?s paper is to increase and deepen the understanding of music's function and significant role in context with its reinforcing sense of visual expression in film. More specifically, it aims to explore the musical value of the expressive aspect of the media text in form of film musical Les Misérables (2012), which has been transmedialised from the novel of the same name, referring to the sound, music and song in relation to the film's visual expression.The research questions are at the core of the essay study: "how is music used to reinforce the cinematic visual expression?" and "how can music signify the narrative and highlight the emotional aspect of the film?" The theoretical framework is based on some of the key scholars assumptions such as Michel Chion (1994) and Claudia Gorbman (1987), who share the same theoretical views that the soundtrack seems powerful when it expresses its participation in a scene?s emotional moods as the music follows the scene?s rhythm, the image?s flow and contributes emotional and musical codes of emotions and expressions. According to Chion sound and image interact together to tell a story where sound enrich the image with expressive and informative values.

The purpose of this paper was to investigate what young behavioral science students, born in the 1980s, think is important in their future work life. The purpose has also been to investigate what attitudes the behavioral science students have towards their future work life, and what place work has in the young behavioral science students lives. After clarification of above, the aim has also been to compare the results with former research. Thereafter the purpose has been to investigate whether traditional work motivation and job satisfaction theories are applicable for young people today. The empirical material is based on interviews with six women who study behavioral science at various levels.

Efter fyra månader som ljudpraktikant på det svenska spelföretaget Starbreeze i Uppsala, var det dags att ta steget vidare i ytterligare fyra månader. Från ljuddesign till scriptning, idéer och tankar, samt en inblick i hur scriptning fungerar. Detta arbete handlar om framtagandet av en ljuddesign-prototyp åt ett externt företags framtida spelprojekt. En utveckling som från början var tänkt att öka kunskaperna om scriptning, och att skapa ett sammanhängande spelscenario, men som sedan utvecklades till att leda mycket längre. Förklaring: Ljuddesign = Ljudläggning av någon form, i detta fall spel. Scriptning = Enklare programmering, kan vara saker som händer eller saker man kan göra i spelet Nyckelord: Soundvolume 2.0, Starbreeze, ljuddesign, spel, sounddesign, 3D.
