  4. 17. Model Based Coding : Initialization, Parameter Extraction and Evaluation

    Author : Zhengrong Yao; Haibo Li; Ralf Schäfer; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Model-based coding; Motion estimation; Vision based tracking; Initialization; Analysis-by-Synthesis; Texture mapping; Active tracking.; Signalbehandling; Signal processing; Signalbehandling; Signal Processing; signalbehandling;

    Abstract : This thesis covers topics relevant to model-based coding. Model-based coding is a promising very low bit rate video coding technique. The idea behind this technique is to parameterize a talking head and to extract and transmit the parameters describing facial movements. At the receiver, the parameters are used to reconstruct the talking head. READ MORE

  6. 19. A model for simulation and generation of surrounding vehicles in driving simulators

    Author : Johan Olstam; Jan Lundgren; Pontus Matstoms; Stéphane Espié; Linköpings universitet; []
    Keywords : Traffic; Simulation; Model; Traffic flow; Vehicle; Micro; Overtaking; Vehicle spacing; Deceleration; Acceleration; Mathematical model; Simulator; Road: Traffic theory; Road: Traffic theory; TECHNOLOGY;

    Abstract : Driving simulators are used to conduct experiments on for example driver behavior, road design, and vehicle characteristics. The results of the experiments often depend on the traffic conditions. One example is the evaluation of cellular phones and how they affect driving behavior. READ MORE

  7. 20. Stochastic model updating and model selection with application to structural dynamics

    Author : Majid Khorsand Vakilzadeh; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite element model; Bayesian model selection; Bayesian model updating; stochastic simulation; Bootstrapping; Subspace system identification; Uncertainty quantification;

    Abstract : Uncertainty induced by our incomplete state of knowledge about engineering systems and their surrounding environment give rise to challenging problems in the process of building predictive models for the system behavior. One such challenge is the model selection problem, which arises due to the existence of invariably multiple candidate models with different mathematical forms to represent the system behavior, and so there is a need to assess their plausibility based on experimental data.
