The DOD operates logistics, defensive, and assault operations in the most hazardous environment constructed by man, namely the modern battlefield. In the 21st Century, the battlefield environment will become so deadly that any exposure of personnel will have high lethality. Applying battlefield robotics will enhance personnel safety and will Aid force multiplication. However, "man-in-the-loop" con ...

N/A

A CONCRETE CONSOLIDATION SYSTEM WILL BE DEVELOPED WHICH TAKES ADVANTAGE OF THE RESONANCE PHENOMENON AND HARMONIC COMBINATION OF INTERNAL AND SURFACE VIBRATIONS FOR EFFICIENTACHIEVEMENT OF UNIFORM AND THOROUGH CONSOLIDATION OF CONCRETE PAVEMENTS. AN INTEGRATED ANALYTICAL-EXPERIMENTAL RESEARCH IS PLANNED TO ASSESS THE TECHNICAL FEASIBILITY AND COST COMPETITIVENESS OF THE PROPOSED APPROACH. ANALYTICA ...

N/A

This proposal aims to develop and adapt a novel optical technique called digital shearography for non-destructive bond evaluation of submarine hull coatings. Shearography is somewhat analogous to a large number of strain gages as it permits full-field measurement of strain distribution. It detects flaws in materials by-detecting flaw-induced strain anomolies. Being full-field, non-contacting, and ...

DYNAMIC QUANTIFICATION OF THE THREE-DIMENSIONAL SURFACE GEOMETRY OF ANTHROPOMORPHIC TEST DEVICES CAN IMPROVE CURRENT INJURY ASSESSMENT CAPABILITIES. PRESENTLY, A CHEST BAND CONSISTING OF MANY STRAIN GAUGES MOUNTED IN A MEMBRANE ARRAY IS BEING USED TO MEASURE DEFORMATION OF THE TORSO. WHILE THIS TECHNIQUE PROVIDES REASONABLE DATA, IT INCREASES THE COSTOF DATA ACQUISITION AND THE TIME TO PERFORM THE ...

N/A

Defensive surf zone emplacements can be undercut by the use of surf actants without eco-damage. Surfactants can decrease the sur- face tension of the sand/water interface to increase the scouring action of wave turbulence around obstructions. Surfactants have been used in oil-well drilling mud for decades to mobilize sand and rock chips for removal as a semi-fluid. This research proposes ...

A THERMOELECTRIC (TE) COOLING DEVICE WILL BE FABRICATED AND TESTED TO DEMONSTRATE A COOLING PERFORMANCE CONSISTENT WITH A FIGURE OF MERIT, Z = 3.5 X 10 -3 K DEG -1. THE PROPOSED METHOD WILL BE TO CAPITALIZE ON THE THERMMODYNAMICS RELATED TO THE THOMSON COOLING EFFECT. THE THOMSON EFFECT PRODUCES COOLING IN ADDITION TO THE PELTIER EFFECT BY VIRTUE OF VARIANCE OF THE SEEBECK COEFFICIENT IN AN OPERAT ...

The project team believes that scalable battery modules, a scalable packaging strategy, a scalable BMS design, and a standardized re-manufacturing process are the missing links necessary to establish a robust repurposed and second-life lithium-ion battery supply chain. The modular and scalable approach will also allow Navitas and GBS to serve markets outside of the transportation industry improvin ...
