  2. 1. Traffic Simulation Modelling of Rural Roads and Driver Assistance Systems

    Author : Andreas Tapani; Jan Lundgren; Haris N. Koutsopoulos; Linköpings universitet; []
    Keywords : Traffic; Micro; Simulation; Model; Car following; Rural road; Driver; Fatigue; Rumble strip; Adaptive cruise control; Active safety system; Safety; Evaluation; Overtaking; Traffic lane; Mathematical model; Thesis; Road: Traffic theory; Road: Traffic theory; TECHNOLOGY;

    Abstract : Microscopic traffic simulation has proven to be a useful tool for analysis of varioustraffic systems. This thesis consider microscopic traffic simulation of rural roads andthe use of traffic simulation for evaluation of driver assistance systems. READ MORE

  4. 2. Numerical Modelling of Short Fatigue Crack Growth

    Author : Per Hansson; Mekanik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; discrete dislocation; Fatigue; grain boundary; short crack;

    Abstract : Fatigue implies repeated loading and unloading of a structure, and components subjected to fatigue might experience nucleation of cracks, and subsequent crack propagation. This might lead to catastrophic consequences, such as complete failure of a structure. READ MORE

  5. 3. Load Modelling for Fatigue Assessment of Vehicles - a Statistical Approach

    Author : Magnus Karlsson; Göteborgs universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Fatigue; customer correlation; road load modelling; design of experiments; vehicle independent load models; lateral loads; road load modelling;

    Abstract : A way of modelling loads in customer usage for fatigue life considerations of vehicles is discussed. The starting point is lateral vehicle loads acting on trucks. Customer usage is described by using road classification. READ MORE

  6. 4. Intelligent Driver Mental State Monitoring System Using Physiological Sensor Signals

    Author : Shaibal Barua; Peter Funk; Shahina Begum; Mobyen Uddin Ahmed; Christer Ahlström; Jose Peña; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Artificial Intelligent; Intelligent systems; Physiological signal; Driver monitoring; Computer Science; datavetenskap;

    Abstract : Driving a vehicle involves a series of events, which are related to and evolve with the mental state (such as sleepiness, mental load, and stress) of the driv- er. These states are also identified as causal factors of critical situations that can lead to road accidents and vehicle crashes. READ MORE

  7. 5. High Strain Fatigue Crack Growth and Crack Closure

    Author : Michael Andersson; Materialteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; materialteknik; Materiallära; Material technology; crack closure; high strain fatigue; crack grotwh;

    Abstract : Understanding of the growth of fatigue cracks is of utmost importance since such growth often has a profound influence on the life of components subjected to cyclic loading. Thus, reliable fatigue life models enable a more efficient use of materials and improve the performance and efficiency in many applications. READ MORE
