The project will remove a key difficulty that currently hampers many existing methods for computing unsteady electromagnetic waves on unbounded regions. Numerical accuracy and/or stability may deteriorate over long times due to the treatment of artificial outer boundaries. We propose to develop a universal algorithm and software that will correct this problem by employing the Huygens' principle an ...

In this STTR proposal, we propose a novel computational technology for analyzing millimeter wave and sub-millimeter wave scattering from complex and electromagnetically extended objects and environments. The core of our formalism lies in a technique for rapidly calculating and coherently adding fields produced by different scatterer constituents, ranging from conducting, flat surfaces to penetrabl ...

Ultrafast true random number generators are ideal for data encryption, Monte Carlo testing, and other data transport applications. Torch"s team has extensive experience designing, building, and testing oscillators based on the innovative, hybrid, exactly-solvable, chaotic oscillator theory as developed by Corron, Blakely and Pethel. These oscillators are capable of generating provably-chaotic wa ...

Autonomous or teleoperated navigation of unmanned ground vehicles (UGVs) is difficult even in benign environments due to challenges associated with perception, decision making, and human-machine interaction, among others. In environments with rough, sloped, slippery, and/or deformable terrain, the difficulty of the navigation problem increases dramatically. In this effort, Quantum Signal, LLC, Un ...

Our objective is to significantly increase the electron transfer efficiency of the enzyme-catalyzed reactions at electrodes and thereby establish a new state-of-the-art power source for military and commercial systems. The approach is to develop a novel method for orienting enzymes immobilized onto the electrode surface that results in facilitated charge transfer. The proposed bio-electrode techn ...

Our objective is to develop a novel method for structurally orienting enzymes onto an electrode surface. The technology will significantly increase the electron transfer efficiency of the electrode and thereby enable a state-of-the-art energy source for low power military and commercial systems. The proposed enzymatic fuel cell (EFC) will leverage ongoing research at both CFDRC and the Universit ...

Chaos is a natural phenomenon that offers unique features that may be exploited to yield communication systems having beneficial characteristics. Useful chaotic oscillators of low-dimensionality can be constructed using simple, inexpensive components."Sensitivity to initial conditions"may be harnessed by means of the Hayes encoder concept to provide modulation of nearly arbitrary efficiency. The ...

Mobile Intelligence Corporation (MIC) and Wayne State University propose a virtual teleoperation and visual landmark navigation system for UGV teleoperation in buildings, tunnels and caves. The challenge is search and navigation in complex structures with sparse visual cues, high-latency low-bandwidth communications, UGVs with low-cost vision sensors, and only intermittent static 2D visual feedba ...

The US Army requires the development of a mmW (90-300 GHz) RCS modeling formalism to support design, analysis, and characterization of objects in this frequency band. The IERUS Technologies and Ohio State Microwave Laboratory team have identified a means of implementing and validating this modeling framework. This method combines IERUS"s extensive computational electromagnetics development expert ...
