1. 16. Reduction of Vulnerable Road User accidents in urban intersections: Needs and challenges in designing Advanced Driver Assistance Systems

   Författare :Azra Habibovic; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vulnerable road user; warning; functional requirement; causation; intersection; accident prevention; advanced driver assistance system; infrastructure-car cooperation;

   Sammanfattning : Advanced driver assistance systems (ADAS) can be used to prevent accidents, or to reduce their severity. It is essential to determine what functional requirements such systems should fulfill to meet drivers’ support needs. An understanding of the underlying contributing factors and context in which the accidents occur is therefore crucial. LÄS MER

3. 17. Towards a method to improve road safety for pedestrians and cyclists especially in child pedestrian environments : a case study in Borås

   Författare :Charlotta Johansson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic Engineering; Trafikteknik;

   Sammanfattning : This licentiate thesis deals with traffic safety of pedestrians and cyclists, especially children, in urban areas. The aim is to develop a method based on video recordings to describe road safety and mobility for pedestrians and cyclists, especially children, at intersections in urban areas. LÄS MER

4. 18. Communication and Positioning Uncertainties in Cooperative Intelligent Transportation Systems

   Författare :Erik M Steinmetz; RISE; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cooperative positioning; resource allocation; cooperative intelligent transportation systems; packet reliability; vehicular communication;

   Sammanfattning : The current road transport system has problems with both safety and efficiency. Future intelligent transportation systems (ITS) are envisioned to alleviate these problems. In particular, cooperative ITS, where vehicles are connected to each other and the cloud, will allow vehicles to collaborate and share both sensor and control information. LÄS MER

5. 19. On Prism-based Motion Blur and Locking-proof Tetrahedra

   Författare :Mads Rönnow; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; continuous collision detection; locking; GPU; parallel; real time; FEM; motion blur; prism;

   Sammanfattning : Motion blur is an important visual effect in computer graphics for both real-time, interactive, and offline applications. Current methods offer either slow and accurate solutions for offline ray tracing applications, or fast and inaccurate solutions for real-time applications. LÄS MER

7. 20. Counting rational points on genus one curves

   Författare :Manh Hung Tran; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Diophantine equations; rational points; Elliptic curves; genus; descent; determinant method; cubic and quartic curves; genus;

   Sammanfattning : This thesis contains two papers dealing with counting problems for curves of genus one. We obtain uniform upper bounds for the number of rational points of bounded height on such curves. The main tools to study these problems are descent and various refined versions of Heath-Brown’s p-adic determinant method. LÄS MER
