1. Tactile Sensory Control of Dexterous Manipulation in Humans
Abstract : During dexterous manipulation with the fingertips, forces are applied to objects' surfaces. To achieve grasp stability, these forces must be appropriate given the properties of the objects and the skin of the fingertips, and the nature of the task. READ MORE

2. To grip and not to slip : sensorimotor mechanisms in reactive control of grasp stability
Abstract : The reactive control of fingertip forces maintaining grasp stability was examined in man during a prehensile task. Blindfolded subjects used the precision grip between the tips of index finger and thumb to restrain an object that was subjected to unpredictable load forces. These were delivered tangential to the parallel grip surfaces of the object. READ MORE

3. Metal fusion using pulsed GasMetal Arc : Melt pool modellingand CFD simulation
Abstract : Pulsed gas metal arc is a highly efficient technique used in manufacturing processes like welding and additive manufacturing. It offers high productivity and cost benefits but it is also prone to defect formation when process parameters are not properly controlled and optimized. READ MORE

4. Dexterous Grasping : Representation and Optimization
Abstract : Many robot object interactions require that an object is firmly held, and that the grasp remains stable during the whole manipulation process. Based on grasp wrench space, this thesis address the problems of measuring the grasp sensitivity against friction changes, planning contacts and hand configurations on mesh and point cloud representations of arbitrary objects, planning adaptable grasps and finger gaiting for keeping a grasp stable under various external disturbances, as well as learning of grasping manifolds for more accurate reachability and inverse kinematics computation for multifingered grasping.

5. Neural correlates of hand function in typically developing individuals and children with unilateral cerebral palsy
Abstract : The ability to use our hands is crucial in order to achieve the goals of almost all activities in everyday life. Most of us learn how to handle objects and adjust our hand and finger movements to perform increasingly difficult tasks during childhood and adolescence. READ MORE
