Novel Foot Orthosis
(2006-12)
The objective of this design project is to implement a device capable of resting the posterior Thetibialis tendon (for less advanced stages of PTT), or (for more advanced cases) to perform the functions of the tendon by ...
PSPACE-completeness of Modular Supervisory Control Problems*
(Kluwer Academic Publishers; Springer Science + Business Media, Inc., 2005-06)
In this paper we investigate computational issues associated with the supervision of concurrent processes modeled as modular discrete-event systems. Here, modular discrete-event systems are sets of deterministic finite-state ...
Effect of fiber inclination on crack bridging stress in brittle fiber reinforced brittle matrix composites
(Elsevier, 1992-08)
behavior of brittle matrix composites is strongly affected by the bridging of cracks by fibers. In random fiber composites, fibers can lie at an angle to the crack plane. Under such conditions, the bridging stress for a ...
Extensional flow behavior of polymer solutions and particle suspensions in a spinning motion
(Elsevier, 1974-06-17)
Mechanical spinning of fluid filaments was used to generate an extensional flow, in which rheological measurements were obtained for a Newtonian fluid, two aqueous polymer solutions, and two fluid suspensions of rod-shaped ...
Alaska Hydro-flow Generator
(2007-04)
Intense multidisciplinary scientific research is conducted at the Bering Glacier in Southwest Alaska. To power the remotely located research camps there, gasoline is flown in by bush planes and used to fuel portable ...
Topology Optimization of Thermally Actuated Compliant Mechanisms Considering Time-Transient Effect
(Elsevier, 2003-12-02)
Thermal transducers, which can be regarded as thermally actuated compliant mechanisms, have found a wide range of applications, due to easy accessibility of heat source, and due to their good controllability and reliability. ...
Optimal Vehicle Motion Control to Mitigate Secondary Crashes after an Initial Impact.
(2015)
Statistical data of road traffic fatalities show that fatalities in multiple-event crashes are higher than in single-event crashes. Most vehicle safety systems were developed to mitigate first crash events. Few active ...
Entropic efficiency of energy systems
(Elsevier, 1992)
Thermodynamic foundations of the thermal entropy production are rested on the concept of lost heat, (Q/T)[delta]T. The thermomechanical entropy production is shown to be in terms of the lost heat and the lost work as where ...
Local Compression in Automated Breast Ultrasound in the Mammographic Geometry
(IEEE, 2010-10-11)
Background, Motivation and Objective: Automated ultrasound scanning (AUS) of the breast has developed more slowly than anticipated. The main limitation, beyond achieving adequate acoustic coupling to the breast, has been ...
