THIS PROPOSAL WOULD ENCOMPASS THE DESIGN AND FABRICATION OF SOLID STATE POWER SWITCHES AS HYBRID CIRCUITS. THE CIRCUITS WOULD CONTAIN PARALLEL OUTPUT TRANSISTORS, ALL REQUIRED CURRENT DRIVE STAGES, HIGHTEMPERATURE AND HIGH-CURRENT PROTECTION. TEMPERATURES ARE MEASURED WITH SCREEN PRINTED OR CHIP THERMISTORS AND CURRENT WILL BE MONITORED AS A VOLTAGE ACROSS A SENSE RESISTOR OR OTHER METHOD YET TO B ...

For over a hundred years, the agricultural base in Hawaii has been sugar cane. In recent years,all plantations on the major islands of Oahu and Hawaii have closed, and many are jobless. Onealternative to work opportunities is specialty crop production, but changes in global trade haveeroded Hawaii's market share through increased competition in U.S. and foreign markets.Problems faced by the indu ...

THE PROPOSED PROJECT WILL DETERMINE THE FEASIBILITY OF THE USE OF ADVANCED TYPE II FLUIDS FOR THE DE-ICING/ANTI-ICING OF GENERAL AVIATION (GA) AIRCRAFT WITH TAKEOFF SAFETY SPEEDS (V2) OF GENERALLY LESS THAN 85 KNOTS. TYPE II FLUIDS WILL BE APPLIED TO SEVERAL GA CATEGORY AIRCRAFT. THE ICE PROTECTION CAPABILITY OF THE FLUID WILL BE EVALUATED FOR DIFFERENT FREEZING PRECIPITATION CONDITIONS. THE EFFEC ...

We will develop a proof-of-concept system that implements an innovative methodology to diagnose and repair unknown satellite anomalies. Our system is based on a novel approach that integrates Case-Based Reasoning (CBR) with Utility Theory. The resulting system deals with unknown and missing information, and selects from a case base the plans or actions that will either fix the satellite or will ...

THIS PROPOSAL DESCRIBES A UNIQUE AND HIGHLY SIMPLIFIED IMMUNOLOGICAL PROCEDURE USING A MONOCLONAL ANTIBODY TO CIGUATOXIN IN A TWO-STEP PROCEDURE. THE MONOCLONAL ANTIBODY(MAB) IS PREPARED BY THE MOUSE HYBRIDOMA TECHNIQUE, USING HIGHLY PURIFIED CIGUATOXIN CONJUGATED TO PROTEIN CARRIERS. THE MAB-CTX THUS OBTAINED IS CONJUGATED TO COLLOIDAL GOLD (< 0.45 UM DIAMETER) OR COLORED LATEX PARTICLES. THIS WI ...

THE PROPOSED ULTRASONIC SPATIAL SENSING AID FOR THE BLIND IS AN ELECTRONIC TRAVEL AID DESIGNED TO PROVIDE THE BLIND TRAVELER WITH SPATIAL CONTEXTUAL INFORMATION, A NECESSARY PREREQUISITE FOR MOBILITY. THE DEVICE OPERATES ON THE ECHOLOCATING PRINCIPLE, BY BROADCASTING ULTRASOUND WHICH IS REFLECTED BY ENVIRONMENTAL OBJECTS. THE RETURNING ULTRASONIC ECHOES WILL BE ELECTROACOUSTICALLY TRANSFORMED INTO ...

The potential of Destructive Adsorbent Technology (DAT) to detoxify sulfur mustard and nerve agents has been demonstrated in the laboratory. DAT employs a new class of reactive adsorbent materials, known as nanoparticles, to detoxify such hazardous substances by removing halogen or phosphorous elements from them. Developed at Kansas State University, DAT has been licensed to Nantek, Inc. for fur ...

The objective of this Phase I is to demonstrate the use of Reactive Nanoparticles (RNP) for the decontamination/sterilization of biological agents and their mimics. Recent studies have shown that RNPs are very effective for chemical agent decontamination at ambient or higher temperature. Examples include paraoxon, VX, half mustard and HD. RNPs themselves are generally made of non-toxic magnesiu ...

Catalytically reactive topical skin protectant (rTSP) for soldiers against chemical warfare agents will be developed based on two complimentary technologies. The first will be an outgrowth of nanoparticle metal oxides as destructive adsorbents, where catalytic action is facilitated by placing monolayers of catalytically active transition metal oxides on nanoparticles of MgO and/or ZnO. Another a ...

This research effort will pursue four key methods of frictional drag reduction identified by Navatek, Ltd. under a prior CEROS MIDFOIL grant as supporting technologies to achieve a very high speed (70-100 knots) large (5,000-10,000 ton) ship. Under this grant, Navatek conceptualized a high-speed ship buoyantly and dynamically supported by high lift-to drag, high operating Froude number (F>1.2) li ...
