1. 1. Modelling and inference of relative collision safety in cars

   Författare :Anna Vadeby; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Collision; Mathematical model; Head on collision; Injury; Risk; Car; 91 Road: Vehicle design and construction; 91 Road: Vehicle design and construction; 85 Road: Personal injuries; 85 Road: Personal injuries;

   Sammanfattning : We propose a new mathematical model for relative collision safety in cars. Our present research is restricted to head-on crashes between two cars and we try to determine how much of the injury risk in a crash that depends on car model. The relative risks include the driver populations of the different car models. LÄS MER

3. 2. Adaptive Bounding Volume Hierarchies for Efficient Collision Queries

   Författare :Thomas Larsson; Björn Lisper; Tomas Akenine-Möller; Stefane Redon; Mälardalens högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bounding volume hierarchies; Collision detection; Rigid bodies; Deformable models; Data structures; Simulation; Animation; Three-dimensional graphics and realism; Computer science; Datavetenskap; Datavetenskap;

   Sammanfattning : The need for efficient interference detection frequently arises in computer graphics, robotics, virtual prototyping, surgery simulation, computer games, and visualization. To prevent bodies passing directly through each other, the simulation system must be able to track touching or intersecting geometric primitives. LÄS MER

4. 3. Formal Methods for Scalable Synthesis and Verification of Autonomous Systems : Mission Planning and Collision Avoidance

   Författare :Rong Gu; Cristina Seceleanu; Kristina Lundqvist; Eduard Paul Enoiu; Rajeev Alur; Mälardalens universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; autonomous agents; synthesis; verification; planning; collision avoidance; formal methods; model checking; Computer Science; datavetenskap;

   Sammanfattning : Autonomous systems (a.k.a., agents) are often designed to move and execute tasks, without or with little human intervention. LÄS MER

5. 4. Towards computational models for road-user interaction: Drivers overtaking pedestrians and cyclists

   Författare :Alexander Rasch; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active safety; vulnerable road users; cyclist safety; driver models; interaction models; overtaking; Euro NCAP; driver behavior; Pedestrian safety;

   Sammanfattning : Introduction: Crashes resulting from a failed interaction between drivers and vulnerable road users, such as pedestrians or cyclists, can lead to severe injuries or fatalities, especially after failed overtaking maneuvers on rural roads where designated refuge areas are often absent, and impact speeds high. This thesis contains two studies that shed light on driver interaction with either 1) a pedestrian or 2) a cyclist, and oncoming traffic while overtaking. LÄS MER

7. 5. Multiparton Interaction Models and Parton Shower Studies

   Författare :Richard Corke; Teoretisk partikelfysik - Geonomgår omorganisation; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Multiparton Interactions; Parton Showers; Phenomenological Models; QCD Phenomenology;

   Sammanfattning : This thesis involves phenomenological models for describing high energy particle collisions. One class of these models, multiparton interactions (MPI), deals with the fact that when colliding two hadrons, it is possible for more than one pair of their constituents to interact. LÄS MER
