Development is proposed of a new, rotary form of Stirling cryocooler which offers longer operating life and much lower vibration than reciprocating forms of cryocoolers. The proposed machine has fewer moving parts to wear and can be completely balanced to eliminate vibration in all planes by simple counterweights on the shaft, which is not possible in reciprocating machines. The rotary desi ...

Ceramic armor is increasingly gaining acceptance as the armor material of choise for defense applications. One way to increase the ballistic performance of ceramic armors is to enhance their fracture resistance br decreasing their gain size (i.e. decreased flaw size) within the microstructure. Nanocrystalline powders, by virtue of their nanometer scale partical size, offer excellent potential to ...

The primary objective of the proposed project is to demonstrate through detailed simulation, performance and low-cost feasibility of SICOM's innovative rapid-acquisition digital data (RADD) demodulator for high data rate burst or CW communications. The demodulator incorporates several innovative features, including zero-preample determination of symbol timing, carrier phase, and carrier frequency ...

A liquid chemical hydride-based hydrogen storage system is proposed for high density hydrogen supply for fuel cell power generation applications. Research works performed at MER showed that certain liquid hydrides can be catalytically dehydrogenated at temperatures as low as 150¿C. The released hydrogen gas can be withdrawn from the system through a hydrogen permeable membrane to achieve comple ...

There is a need for a passive sampler that can measure chemical simulant vapor concentration in real time, and under nuclear- biological- chemical-protective light-weight clothing. Existing samplers and sampler design concepts are not able to meet this need because of bulk, difflision limitations, contamination potential, durability, sensitivity, selectivity, reliability, and cost. Nanomaterials ...

DESCRIPTION (Investigator's Abstract): The application proposes to engage in teacher education workshops focussing on issues pertaining to drug abuse particularly the neurobiology thereof. Workshops will be provided for teachers from experts in the field. Our main goal in this science education project is to impart useful knowledge and information to teachers of grades 7 -12. In an era of de ...

In this study six techniques for effectively modeling and analyzing the trajectories of future space systems are investigated. These techniques are grouped into methods for modeling trajectories by conversion to a mathematical programming problem, and methods for solving mathematical programming problems. The first group includes parallel shooting, high-order collocation and differential inclusi ...
