  2. 1. Tracking Theory for Preventive Safety Systems

    Author : Lars Danielsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle tracking; sensor data fusion; automotive; active safety systems; sensor models; warning integration; motion models; fusion strategies; human machine interface; preventive safety systems;

    Abstract : Preventive safety systems rely on accurate information from a sensing system regarding the current traffic situation to make decision whether to inform, warn or intervene to avoid an impeding collision or to mitigate its consequences. This thesis mainly considers tracking algorithms to enhance these systems through making the best use of the information supplied by on-vehicle sensors, such as radar and vision sensors. READ MORE

  5. 3. Fast Adaptive Numerical Methods for High Frequency Waves and Interface Tracking

    Author : Jelena Popovic; Olof Runborg; Hongkai Zhao; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; high frequency waves; Helmholtz equation; interface tracking; time-space adaptivity; multiresolution; Hamilton-Jacobi;

    Abstract : The main focus of this thesis is on fast numerical methods, where adaptivity is an important mechanism to lowering the methods' complexity. The application of the methods are in the areas of wireless communication, antenna design, radar signature computation, noise prediction, medical ultrasonography, crystal growth, flame propagation, wave propagation, seismology, geometrical optics and image processing.

  6. 4. Theoretical and Experimental Investigations of Nonlinear Flame Instability

    Author : Li-Zheng Ma; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nonlinear hydrodynamic instability; flame propagation and stretch effects; shock induced flame instability; tulip flame formation; interface tracking; the Schlieren technique; level set approach;

    Abstract : Flame instability is both important and difficult to understand. Mechanisms of instability are complex, because instability often involves an interaction between several different physical phenomena, such as an unsteady chemical reaction, unsteady flame propagation generating an unsteady flow, acoustic waves or shock waves.

  7. 5. Gameplay (3D Game Engine + Ray Tracing = Visual Attention through Eye Tracking)

    Author : Charlotte Sennersten; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Spelutveckling; Game development; Cognition; Vision; Gameplay; Instrumentation; 3D Game Engine; Eyegaze tracking;

    Abstract : Research into gameplay can contribute to more self-conscious approaches to design, allowing designers to create effective gameplay with less testing, or to target specific cognitive and emotional affects of gameplay for serious games applications. Self-conscious design includes theoretically motivated design of game systems to facilitate gameplay motivated by cognitive, scientific and/or rhetorical theories of game affect and functionality.
