Disturbance observer based closed loop control of haptic interfaces
Traditionally, control of haptic interfaces is achieved using open-loop impedance or admittance control. During open-loop control, the quality of haptic feedback is limited by the dynamics of the haptic device. Further ...
Synthesis and chemical modification of carbon nanostructures for materials applications
This dissertation explores the structure, chemical reactivities, electromagnetic response, and materials properties of various carbon nanostructures, including single-walled carbon nanotubes (SWCNTs), multi-walled carbon ...
Plasticity, localization, and friction in porous materials
Original variations of two-invariant rate-independent plasticity models capture many features of the homogeneous behavior of porous materials. All of the variations proposed are based on a simple 7 parameter critical state ...
Hybrid finite elements nanocomposite characterization by stochastic microstructuring
In this thesis the impact of entangled and non-straight fibers in the determination of the effective elastic and thermal properties of polymer nanocomposite (PNC) is addressed. Most of the models in recent studies assume ...
Computational study of defects dynamics in carbon nanotubes and fullerenes
In this dissertation, statics and dynamics of defects in fullerenes and carbon nanotubes are studied by various computational model, such as ab initio (DFT, semi-empirical, empirical potential) and several computational ...
