  2. 1. Lithium ion Battery Aging: Battery Lifetime Testing and Physics-based Modeling for Electric Vehicle Applications

    Author : Evelina Wikner; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Calendar aging; Physics-based modeling; Battery lifetime tests; Plug-in Hybrid Electric Vehicle PHEV ; Electric Vehicle EV ; Hybrid Electric Vehicle HEV ;

    Abstract : Electrification of vehicles is one solution in reducing emissions from the transport sector, and in particular to limit tail-pipe emissions in cities. In order to make the electrification successful and cost effective, there is a high demand for longer drive range and longer battery lifetime. READ MORE

  4. 2. Realistic Package Opening Simulations : An Experimental Mechanics and Physics Based Approach

    Author : Eskil Andreasson; Blekinge Tekniska Högskola; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymer; aluminium foil; semi-crystalline; progressive damage; Abaqus;

    Abstract : A finite element modeling strategy targeting package opening simulations is the final goal with this work. The developed simulation model will be used to proactively predict the opening compatibility early in the development process of a new opening device and/or a new packaging material. READ MORE

    Abstract : Medical imaging continues to permeate the practice of medicine, but automated yet accurate segmentation and labeling of anatomical structures continues to be a major obstacle to computerized medical image analysis (MIA). Deformable models, with its profound roots in estimation theory, optimization, and physics-based dynamical systems, represent a powerful approach to the general problem of medical image segmentation.

  7. 5. Radio Channel Prediction Based on Parametric Modeling

    Author : Ming Chen; Chalmers University of Technology; []
    Keywords : Wireless communications; channel prediction; GLRT; CRLB; NLLS; polynomial phase signal; Kalman filter; NILS.; sinusoidal modeling; channel modeling; MIMO;

    Abstract : Long range channel prediction is a crucial technology for future wireless communications. The prediction of Rayleigh fading channels is studied in the frame of parametric modeling in this thesis.Suggested by the Jakes model for Rayleigh fading channels,deterministic sinusoidal models were adopted for long rangechannel prediction in early works.
