Harmonic drive gear reducers were developed during the mid-1950's and are used in many industrial and military applications. The harmonic drive is a compact, "in-line" gear reducer capable of producing reduction ratios of ...

Virtual reality has been used widely as a computerized medium for training. In addition to visual and auditory feedback, the addition of haptic feedback to virtual environments envisions promising applications for human ...

The flow in a helical duct is characterized by increased fluid mixing, accomplished by the inducement of a secondary flow in the plane normal to the helix centerline. Two independent phenomena interact to produce this ...

The Team for Advanced Flow Simulation and Modeling (T☆AFSM) at Rice University has been developing the Stabilized Space--Time Fluid--Structure Interaction core technologies in conjunction with an array of special ...

This thesis presents a non-linear model for the thermal and elastic properties of single-walled carbon nanotube reinforced polymer composites. Finite Element Analysis (1-EA), in conjunction with the Embedded Fiber Method ...

The current study examined the transition region of axisymmetric isothermal and buoyant jets of low Reynolds number, directed vertically upwards into a stagnant, unstratified ambient. These flows were examined experimentally ...

A geometric nonlinear filter (GNF) is designed for application to the problem of tracking a maneuvering aircraft. The aircraft tracking problem is a state estimation problem and a state prediction problem. A nonlinear ...

The propagation of antiplane waves in an elastic solid containing a random distribution of cracks that are parallel to each other, and oriented at an arbitrary angle relative to the direction of the incident wave, is ...

Various systems and structures are subjected to impact loading in industrial and military applications. Many of these impact loads have very high magnitudes and very short durations, resulting in high frequency content. ...
