18. An Intelligent Non-Contact based Approach for Monitoring Driver’s Cognitive Load
Abstract : The modern cars have been equipped with advanced technical features to help make driving faster, safer and comfortable. However, to enhance transport security i.e. to avoid unexpected traffic accidents it is necessary to consider a vehicle driver as a part of the environment and need to monitor driver’s health and mental state.

19. Riemannian Manifold-Based Modeling and Classification Methods for Video Activities with Applications to Assisted Living and Smart Home
Abstract : This thesis mainly focuses on visual-information based daily activity classification, anomaly detection, and video tracking through using visual sensors. The main reasons for adopting visual-information based methods are due to: (i) vision plays a major role in recognition/classification of activities which is a fundamental issue in a human-centric system; (ii) visual sensor-based analysis may possibly offer high performance with minimum disturbance to individuals' daily lives.

20. Implementation, identification, and adaptation of Preisach like hysteresis models
Abstract : The extended generalized Prandtl-Ishlinskii model (XGPI) of hysteresis has a wide applicability, partly because of its capability of modelling highly asymmetric hystereses. For a given parameterization, it is typically identified using non-linear least squares optimization with concomitant problems of convergence, dependence on initial parameter guess and local minima.
