Mätning och analys i 3-D för applikationer inom
processindustrin
I denna rapport presenteras en översikt över några befintliga metoder för mätning i 3 dimensioner baserade på bildbehandling och strukturerat ljus. Mätning via triangulering med laserplan och kamera beskrivs och har implementerats i Visual C++. En kalibreringsprocedur för denna mätmetod som med hjälp av laserplanet belyser ett referensobjekt beskrivs också och har utvecklats i MATLAB. Ett antal olika mätningar har sedan utförts med den implementerade mät- och kalibreringsmetoden och vissa initiala analyser av mätdata i MATLAB har gjorts för att ligga till grund för eventuell fortsatt produktutveckling och forskning..
Studie av utvecklingsverktyg med inriktning mot PLC-system
Datoranvändningen i samhället växer för varje dag. Det är då viktigt att programvara håller hög kvalité, då vissa programvaror styr kritiska maskiner som exempelvis flygplan. Ett sätt att få kvalitativa programvaror är att använda bra utvecklingsverktyg. I detta arbete utvärderas fem olika utvecklingsverktyg: GNAT (Ada), Microsoft Visual C++, Microsoft J++, Borland Delphi och Active Perl. Inriktningen på utvärderingen är mot utveckling av programvara för PLC-system.
Gångvägsljus :
Discussing light and lighting in the night-time environment of Tensta, a Stockholm suburb built between 1962 and 1970, this thesis suggests that lighting should be designed for the outdoor environment as a whole. The feeling of safety and human perception are important components in this thesis.
Starting with some comments on visual perception and how we adapt our sight to an interval of the visual input we get, makes it possible to understand that more light sometimes hides, rather than reveals, things. Amongst the dispersed houses, in the green parks of Tensta, this turns the pedestrian roads, lit by pole-top-mounted fixtures, into light tunnels in a dark surrounding.
Talking about the feeling of safety I am inspired by, amongst others K. Lynch, B. Hjort and J.
Avskiljning av ammoniumkväve och fosfatfosfor i reaktiva filtermaterial : skak- och kolonnförsök
In Sweden more than 400 000 private households have not yet sufficient wastewater purification. These effluent is considered as an increasing problem and many onsite purification methods have been studied. In this investigation, the method of reactive bed filters have been tested by column and batch experiments. Five different kinds of filter materials with reactive surfaces have been studied concerning their capacity to absorb ammonium and phosphorus from wastewater. The materials that were examined are Filtra N, wollastonite Filtra P, blast furnace slag and Polonite®.
To reject the world - to embrace the world
Ever since Thomas More?s book Utopia was published in 1516, theutopian idea has not lost its topicality and has been strongly rootedin literature, art, film and architecture. Utopia can be seen as a statein which utopia allows a space for wishes, dreams and a desire forsomething better. In my degree project I have chosen to explore thehistorical utopian ideas to create a content that treats utopia on asubjective level. With visual communication as a starting point I havetried to fixate this state in a book.

Matte painting och camera projection inom VFX-produktion
Matte painting och camera projection är ett relativt snabbt och kostnadseffektivt sätt att skapa miljöer som inte existerar. I denna rapport redovisar jag om matte paintings användning inom VFX-produktion och går igenom hur man uppnår ett effektivt arbetsflöde med godtagbara slutprodukter. Jag redovisar skillnaden mellan 2D, 2.5D och 3D-genererade miljöer och vad som bör användas vid olika situationer. Jag rapporterar även om områdets generella utveckling samt i vilken riktning dess utveckling ser ut att gå..
WCeco2008 : Extremt snålspolande toalett
This thesis is performed in cooperation with Prodelox AB and JTI (Swedish Institute of Agricultural and Environmental Engineering). The purpose of the project is to generate and develop a WC-technique with a closet sewer that keeps a higher TS-substance than 1.5 %. The WC-technique is mainly directed towards permanent households in sparsely-populated areas and cabins. The goal is to generate concepts of toilets with an extremely low use of water in terms of flushing. The design should be appealing and touch more senses than only the visual.
Flexibla fixturer i bearbetande maskiner
This thesis was conducted at Linköping University and Saab Aerostructures DPS, Linköping, and focuses on the possibilities of flexible fixturing in machining applications. The thesis is part of the research project "Koofix", which is collaboration between Linköping University and a number of companies.The thesis is aimed towards small batch production which, for Saab Aerostructures DPS, means diverse part geometry and that parts are manufactured in very small numbers, sometimes just one piece. The result of this is that expensive dedicated fixtures are made for most parts. By introducing more flexible fixturing methods to this kind of production the cost of fixtures and tooling will be reduced, and make the production more efficient.New flexible fixturing methods has been presented and evaluated through the thesis, which has resulted in three different concepts. These concepts have been the result of literature screening and study of current manufacturing process at Saab Aerostructures DPS.
Time and architectural representations: the illusion of being eternal
Att beskriva en byggnad som tidlös är bland det finaste en kan säga. Några av världens mest uppskattade byggnader har beskriv- its som just det, tidlösa. Hur kommer det sig att en av den finaste komplimangen och erkännandet en byggnad kan få, egentligen är intetsägande?
Tiden går ständigt och det finns ingenting någon kan göra för att ändra det. Människor, djur och även byggnader utvecklas och åldras.
Animerad musikvideo - Anna von Hausswolff
This was a project of creating an animated music video for Anna vonHausswolffs song Something is missing. By working with animation Iwanted to broaden my expertise in visual communications. This hasbeen an exploratory work in how I could translate my illustrations tomoving images in the program Adobe Aftereffects. I have formed myown narrative by creating a storyboard. I worked with illustrated setdesign, created an atmosphere in the film and experimented with howto tell a subtle story.
Examensprojekt: WERA Stockholm
This project is an attempt at creating a bag that is both functionaland has an interesting and relevant visual appearance. I have found that a bag that is functional usually have adapted certain aesthetics which are appealing only to a very limited target group. At the same time many bags that are more focused on style can be downright disabling to the carrier. I wanted to create a functional bag, and to explore new functions doing this, while working with aesthetics that stayed relevant and interesting to my target group. The bag was designed for the company Åhléns and their label WERA Stockholm, and theircustomers was the target group.
Förbättring av upplösningen i Landsat 7-bilder med hjälp av bildfusion
The purpose of this master's thesis is to evaluate whether it is feasible to use the panchromatic band of Landsat 7 in order to improve the spatial resolution of colour images. The images are to be used as texture in visual databases for flight simulators and for this reason it is important that the fusion preserves natural colours.A number of methods for fusing panchromatic and multispectral images are discussed. Four of them are implemented and evaluated. The result is that standard methods such as HSI substitution are not suitable for this purpose since they do not preserve natural colours. However, if only high frequencies of the panchromatic image are used the resolution can be improved without noticeable colour distortion..
