16. Biomechanical consequences of gait impairment at the ankle and foot : Injury, malalignment, and co-contraction
Abstract : The human foot contributes significantly to the function of the whole lower extremity during standing and locomotion. Nevertheless, the foot and ankle often suffer injuries and are affected by many musculoskeletal and neurological pathologies. READ MORE

17. Effect of high-temperature drying on spruce and larch Shape stability, mechanical properties and mould growth
Abstract : Shape stability, the ability of the wood to retain its shape, is one of the most important parameters when using timber as a building material and for other applications. Generally, timber undergoes changes in dimensions and shape when its moisture content is changed. READ MORE

18. Vibrations and Dynamic Isotropy in Hexapods - Analytical Studies
Abstract : The present work was initiated based on an industrial demand for designing a high-bandwidth hexapod of an advanced large optical telescope. In this dissertation, we have generalized this industrial problem to fully-parametric models of the hexapod vibrations as well as analytical studies on dynamic isotropy in parallel robots, which can be directly used in any hexapod application.

20. Measures to Enhance the Dynamic Performance of Railway Catenaries
Abstract : The pantograph-catenary system is used in railways to transfer electric power from infrastructure to trainset. As the pantograph slides against the catenary, the contact between the two surfaces is not stable due to stiffness variation, propagating wave and other environmental perturbation, especially at high speeds or in multi-pantograph operation.
