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 ...
Special-purpose modeling techniques for ringsail parachutes
The Team for Advanced Flow Simulation and Modeling (T☆AFSM) at Rice University developed and advanced stabilized space-time fluid-structure interaction (SSTFSI) technique for the purpose of accurately modeling complex fluid ...
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 ...
New generation valves and seats for reciprocating well servicing pumps
Valves and seats in well servicing reciprocating pumps have a short life as a result of the severe operating conditions. In this work, I present the development of valve and seats concepts that have the potential to last ...
Improved modeling techniques for arterial dynamics and blood flow
The Team for Advanced Flow Simulation and Modeling (T☆AFSM) has recently applied its finite element methods for Fluid-Structure Interactions (FSI) to the simulation of blood flow and arterial mechanics. The Sequentially-Coupled ...
Processing and evaluation of a carbon fiber/epoxy composite reinforced in the interlaminar region with carbon nanotubes and nanofibers
This study demonstrates that introducing Carbon Nanotubes (CNTs) and Vapor Grown Carbon Fibers (VGCFs) into the interlaminar region of a carbon fiber/epoxy composite can enhance the resistance to delamination of the material. ...
