Researchers will conduct a pilot study with a socio-economically and diverse sample of at least 500 high school students who will test the prototype ROI tool. The researchers will examine the feasibility and usability of the prototype, whether ROI information increases search and discovery for educational opportunities; whether having ROI information increases the likelihood of click-through rates ...

The goal of this project is to develop a validated, commercial quality reagent kit for the reliable collection of fingerprints (i.e., latent ridge impressions) that would subsequently be used for both comparison and DNA profiling. The kit would provide all required materials, reagents, solutions and would include a detailed protocol describing the steps to (i) identify latent ridge impressions (al ...

Not Available Modern satellite-communication transmitters use a single antenna array to form multiple beams. Each power-amplifier (PA) module must amplify multiple carriers simultaneously. The resultant high peak-to-average ratio causes conventional PAs to be very inefficient (5-10 percent). Kahn-technique (EER) transmitters combine nonlinear RF amplifiers with a high-level modulator to implement ...

Not Available Herein, a Phase I program is proposed to design, build, and evaluate actuator for a high field, high strain, dynamic environment to ultimately support a buffet load alleviation system. These actuator improvements include high field and dynamic field testing of Active Control experts (ACX), Inc. current interdigitated design, as well as the inclusion of fine grain piezoceramic elemen ...

Not Available Technology in Blacksburg (Techsburg) is proposing an innovative method to reduce inlet distortion and improve the performance of propulsion systems in unmanned air vehicles (UAVs). These vehicles (as well as other tactical aircraft) use serpentine inlets to improve the stealth characteristics of the plane. Unfortunately, these serpentine ducts cause flow separation and increase the ...

SIDEWALK RAMPS, ADOPTED FOR THE SAFETY AND CONVENIENCE OF WHEELCHAIR BOUND CITIZENS, HAVE EXHIBITED A NUMBER OF SHORTCOMINGS. MILLIONS OF DOLLARS HAVE BEEN SPENT, AND WILLCONTINUE TO BE SPENT, FOR THE CONVERSION OF CURBS INTO RAMPSA LESS THAN SATISFACTORY SOLUTION TO THE PROBLEM. A MORE FEASIBLE APPROACH TO ALTERING THE MILLIONS OF CURBS IS THE ADDITION OF CURB CLIMBING CAPABILITIES TO THE FIFTY T ...
