  1. 6. Safety Evaluation Using Counterfactual Simulations: The use of computational driver behavior models in crash avoidance systems and virtual simulations with optimal subsampling

    Författare :Xiaomi Yang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conflict and crash avoidance; safety assessment; active sampling; Advanced Driver Assistance Systems; Automated Driving Systems; counterfactual simulation; scenario generation; car-to-VRU;

    Sammanfattning : Traffic safety is a problem worldwide. In-vehicle conflict and crash avoidance systems have been under development and assessment for some time, as integral parts of Advanced Driver Assistance Systems (ADAS) and Automated Driving Systems (ADS). LÄS MER

  3. 7. Factors Associated with Motorcylists' Safety at Access Points along Primary Roads in Malaysia

    Författare :Marizwan Manan; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; access point; primary road; motorcyclists’ behavior; Safety Performance function; Motorcycle accident fatality;

    Sammanfattning : More than 50% of road accident fatality victims in Malaysia are motorcyclists, numbering more than 4,000 fatalities per year. The aim of this thesis is to investigate motorcyclists’ road safety problems in general in Malaysia, and narrow down the focus to the most salient road infrastructure related risk factors. LÄS MER

  4. 8. Real-Time Algorithms and Intersection Test Methods for Computer Graphics

    Författare :Tomas Möller; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; texture; ray tracing; radiosity; color; three-dimensional graphics and realism; virtual reality; algorithms; shadowing; shading;

    Sammanfattning : In real-time computer graphics applications, at least three major forces are in conflict, namely, rendering speed, the level of realism, and interactivity. Therefore this thesis focuses on real-time algorithms that enhance the realism while maintaining high rendering speed, and on fast intersection test methods in order to speed up, for example, collision detection, picking processes and ray tracing.

  5. 9. Optimal Predictive Control of Wheel Loader Transmissions

    Författare :Tomas Nilsson; Jan Åslund; Lars Nielsen; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The transmissions of present heavy wheel loaders are in general based on torque converters. The characteristics of this component suits these machines, especially in that it enables thrust from zero vehicle speed without risk of stalling the engine, without active control. LÄS MER

  7. 10. Design and Implementation of a Maritime Traffic Modeling and Anomaly Detection Method

    Författare :Ewa Osekowska; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Nowadays ships are usually equipped with a system of marine instruments, one of which is an Automatic Identification System (AIS) transponder. The availability of the global AIS ship tracking data opened the possibilities to develop maritime security far beyond the simple collision prevention. LÄS MER
