ROBOTIC MACHINES THAT DUPLICATE THE MANIPULATIVE SKILLS OF AHUMAN OPERATOR ARE CRITICALLY NEEDED IN COMMERCIAL NUCLEAR POWER PLANTS TO REDUCE OPERATOR EXPOSURE IN HIGH-RADIATION AREAS. ROBOTIC SYSTEMS WITH FORCE REFLECTION (FORCE INFORMATION REFLECTED THROUGH A CONTROL JOYSTICK) AND THREE-DIMENSIONAL VISUAL FEEDBACK CAN IMPROVE TASK PERFORMANCE AND REDUCE FATIGUE. THIS RESEARCH PROJECT WILL USE A ...

THE NATION DESIRES TO EXPAND THE USE OF CLEAN BURNING, COMPETITIVELY PRICED NATURAL GAS. THE INCREASED DEMAND FOR NATURAL GAS HAS PROMPTED NEW DRILLING IN ESTABLISHED GAS FIELDS. THE PROPER PLACEMENT OF THE NEW WELLS IS DEPENDENT ON THE GAS FORMATION PROPERTIES BETWEEN THE EXISTING WELLS. ONE OF THE PROPERTIES IS THE THICKNESS OF THE GAS BEARING ZONE. IT IS GENERALLY ACCEPTED THAT THE FORMATIO ...

REMEDIATION OF SOIL AND GROUNDWATER TO REDUCE HEAVY METAL CONTAMINANTS TO BACKGROUND LEVELS POSES A SERIOUS CHALLENGE. CONVENTIONAL METHODS ARE ABLE TO REDUCE CONTAMINATION LEVELS, BUT TOTAL REMEDIATION, DEFINED AS ACHIEVEMENT OF BACKGROUND LEVELS OF THE METAL, MAY NOT BE ECONOMICALLY FEASIBLE. A PERMEABLE CHELATION BARRIER CONTAINING SILICA GEL MODIFIED TO CHELATE HEAVY METALS PROVIDES AN ECONO ...

40690 TPL, Inc. This project will develop a novel solid polymer electrolyte (SPE) that will significantly increase the practical power and energy density of state-of-the-art secondary lithium batteries. The approach will yield carbosilane-based electrolytes with high conductivities and low transference numbers. Covalently attaching thin films of these novel electrolytes to high energy density c ...

TRADITIONALLY, SUPE2RCONDUCTING CAVITIES FOR LARGE ELECTRON POSITION COLLIDERS ARE FABRICATED FROM HIGH PURITY NIOBIUM (NB) SHEETS USING LATHE SPINNING AND WELDING. THESE CAVITIES SUFFER FROM THE PROBLEM OF THERMOMAGNETIC BREAKDOWN RESULTING FROM THE RELATIVELY POOR THERMAL CONDUCTIVITY OF NB AT LIQUID HELIUM TEMPERATURES. A MORE ELEGANT AND LOW COST SOLUTION TO THE BREAKDOWN PROBLEMS IS THE USE ...
