1. 21. Functional Properties of Concrete Roads - Development of an Optimisation Model and Studies on Road Lighting Design and Joint Performance

   Författare :Malin Löfsjögård; KTH; []
   Nyckelord :concrete; roads; functional properties; optimisation model; road lighting; joint performance;

   Sammanfattning : The roads constitute a major part of the nation’sinfrastructure. For the society and the individuals it isimportant with a well functioning road network. To sustain theimpact from traffic intensity and heavy loads durable pavementsare demanded. LÄS MER

3. 22. Improved Algorithms for Fast Shading and Lighting

   Författare :Anders Hast; Ewert Bengtsson; Jos Stam; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; Computer Graphics; Datavetenskap; Computer science; Datavetenskap;

   Sammanfattning : Shading is a technique that is used in computer graphics to make faceted objects appear smooth and more realistic. In the research presented in this thesis we have investigated how shading can be generated as efficiently as possible without sacrificing quality. LÄS MER

4. 23. Real-Time GPU Techniques for Advanced Lighting Phenomena

   Författare :Markus Billeter; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Shading; Rendering; Participating Media; Volumetric Shadows; Mobile Graphics; Scattering; Computer Graphics; GPGPU; Many-Light;

   Sammanfattning : In the real world, the visual perception of an object is completely determined by the object's interactions with light. One large application of computer graphics is to visualize virtual objects and worlds in a fashion that is familiar to humans. Successfully emulating light and its effects on virtual objects therefore plays a central role. LÄS MER

5. 24. Light Rhythms : Exploring the Perceptual and Behavioural Effects of Daylight and Artificial Light Conditions in a Scandinavian Context

   Författare :Federico Favero; Roberto Bresin; Arne Lowden; Ute Besenecker; Sergio Altomonte; KTH; []
   Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; Lighting design; Context; Light; Behaviour; Perception of light; Perception of time; Associative aspects; Architecture; Daylight; Media Technology; Medieteknik;

   Sammanfattning : This compilation thesis collects multidisciplinary work on the study of the impact of light rhythms on perception and behaviour. The thesis was structured to answer and discuss the questions: “How does a person feel and behave inan illuminated space?” and “Do variable light conditions influence perception, appraisal and motion?”.

7. 25. Evaluation of Road Equipment with Emphasis on Condition Assessment

   Författare :Sven-Olof Lundkvist; Ulf Isacsson; Rolf Magnusson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road equipment; Condition assessment; State-of-the-art; Mobile measurement; Road marking; Road sign; Post delineator; Traffic light; Street lighting; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

   Sammanfattning : This doctoral thesis deals primarily with condition assessment of road equipment. The road equipment concept is defined by five main groups, road lighting, fences and barriers, vertical signs, horizontal signs and traffic signals, respectively. LÄS MER
