Purpose: Prior research has shown that students who are considered to be gifted generally have high levels of academic performance, motivation, creativity, critical thinking skills, and positive self-concepts. Perhaps because the general perception is that gifted students will flourish under any conditions, support for gifted children may be limited within some schools. The purpose of this project ...

Purpose: With national attention on the shortage of STEM (science, technology, engineering, and mathematics) professionals, enrollment in science is expected to be on the rise in the years to come. Laboratory work is seen as an essential part of many STEM courses, because labs enable students to interact with natural phenomena and analyze collected data. Funding adequate labs, however, has become ...

This project optimizes haptic system design parameters and more thoroughly evaluates the impact of a vibratory haptic system for prosthetics. Objectives include: (1) building a hardware and software test bed for non-invasive voluntary control of a prosthetic hand with vibratory haptic feedback, (2) optimizing the tactor application, (3) assessing the effectiveness of tactor vibratory feedback on c ...

The objective of this proposed Phase II work is to develop a production method for manufacturing rolled plates of a high-strength aircraft aluminum alloy (7075) with high SCC (stress corrosion cracking) resistance. The corrosion resistance is to be improved without a loss in tensile strength. The basic operational processing procedure is to produce aluminum alloy plate through roll bonding of a co ...

Through this research effort, DSR is developing test equipment that can be used by the Air Force to investigate inert and live explosive material properties through a variety of different pressure and temperature environments. Strain-rate levels are adjustable and will vary between 10-5-10-2 s-1 depending upon the stiffness and strength of the test material. 25.4-mm-diameter specimens with lengt ...

The trend toward replacement of highly toxic chemicals with less hazardous alternatives has created the demand for replacement of chromate conversion coatings for corrosion protection of aluminum alloys. Aluminum alloys are the predominate structural material used in aircraft because of their high strength-to-weight ratios, affordability and processability. Aluminum is subject to catastrophic fail ...

Many speech- and visually-impaired individuals can benefit from text-to-speech systems for unlimited vocabulary speech synthesis. The demands on these systems are especially severe in the case of voice output communication aids (VOCAs) for speech-impaired individuals, since the speech produced substitutes for a speaker's own voice. VOCA quality thus depends not only on intelligibility, but on th ...
