Purpose: In previous research and development, the team created LiveSchool, a technology for teachers to report student behavior in their class. In this project, the team will fully develop and test ClassCoach, a dashboard for administrators to track student behavior and to recommend resources teachers can use to address student behavioral needs in their classes. Over the past several years, schoo ...

Nanohmics proposes to develop a hyperspectral imager for aft-looking sensing of phenomenology associated with target vehicles.The payload is designed to operate with existing components and has no moving parts.The high spectral resolution will provide feedback for signature models and the spatial resolution will allow the spectral signatures to be associated with specific phenomena.Approved for Pu ...

Explosions and high-velocity impacts can create strain rates on the order of 105 to 107 s-1. To simulate these events, first-principles codes require material models that are valid at these loading rates. Currently, the amount of test data, material models and material constants for this strain rate range is extremely limited, and an innovative and cost-effective laboratory test procedure is neede ...

The main goal of this project is to design, develop, and demonstrate an innovative Ontology Driven Integration Framework (ODIF). We propose a hybrid approach that combines knowledge extraction techniques with ontology analysis methods to automatically extract knowledge from distributed, unstructured text sources and facilitate the integration and sharing of this knowledge for space launch and ran ...

The goal of the Phase II program is to fabricate high voltage high power converter/inverters for high frequency/high temperature operation using enhancement mode-depletion mode insulating ate AlInN-GaN/i-SiC transistor building blocks. Our technical approach is to use lattice matched AlInN-GaN epilayers in conjunction with a field-plated insulating gate HEMT device design and a fluorine treatment ...

Recognizing the mission strategic importance of a compact, rad-hard, highly efficient battery management system, Arkansas Power Electronics International, Inc. (APEI, Inc.) is proposing to develop the next generation of rad-hard battery management power converters. This new generation of battery management converters will harness the extreme radiation-hardness of silicon carbide (SiC) junction fi ...

The resource allocation problem and the associated resource management solution is composed of three levels. At the highest level is the game theoretic mapping of alternative offense and defense actions, much like a chess game. At the next level is the large-scale efficient mathematical optimization formulation of the game theory matrix. At the last level is the solution of each optimization sub-p ...

HIGH-DENSITY ENERGY STORAGE AND FAST DISCHARGE WILL BE CRITICAL IN A VARIETY OF HIGH POWER AEROSPACE APPLICATIONS. CAPACITORS ARE IDEAL FOR THESE PURPOSES, AS WELL AS FOR POWER CONDITIONING AND FILTERING. UNFORTUNATELY, BULK POWDER-BASED DIELECTRICS USED IN CAPACITORS HAVE SEVERE LIMITATIONS, ESPECIALLY THE HIGH NUMBER OF SHORT-INDUCING DEFECTS CAUSED BY POOR CONTROL OF MATERIAL PROPERTIES IN CERA ...

The proposed effort focuses on the need for innovative, space realizable, self-contained actuators for precision positioning and vibration isolation. The proposed mechanism is a sealed linear actuator capable of high bandwidth (O-lkHz) control. A design feasibility study will be performed on the use of piezoelectrics in an innovative configuration to provide robust linear actuation for positioning ...

An innovative discharge geometry for a very compact, area cooled, high average power CO2 laser employing a two mirror, waveguide-stable optical cavity is proposed. The specific Phase I result sought is the generation of an average CO2 output power of 1 W/cm2 of wall cooling area in a geometry that has a total cooling area of 140 cm2. A lightweight CO2 amplifier version of a future Phase II devic ...
