Graspable Math Activities is web application that middle and high school students use on laptops and tablets to practice algebra and receive instantaneous feedback. Activities are based on an algebra notation technology that can promote procedural fluency while allowing students to focus on strategy and the connection between concepts and procedures. The team will produce a website that will inclu ...

FastVDO will develop a software testbed to simulate communications of full motion video over wireless links. In particular, FastVDO will study the effects of channel errors on the transmission of compressed video, specifically with H.264 and H.265 compression. The received video will be analyzed for quality using a variety of tools and metrics, and a quantitative analysis will be made of the error ...

This proposal addresses the Program Executive Office for Missiles and Space (PEO M&S) need for an embeddable, extensible, modular, scalable and component-based Common Track Protocol (CTP) Adaptive Translator Module database and software that must account for different ways that track information from multiple Tactical Data Links (TDL) protocols are correlated, recorded and transmitted to end-users ...

Standalone power systems and tactical microgrids are used by the Army to provide power to equipment used in theater. Unlike a full-scale power grid, Army tactical microgrids are powered by 60 kW generators. Because these generators are very small sources compared to those on a full-scale power grid, they are sensitive to power surges, inrush current, and current harmonics generated by non-linear l ...

Paper Spray mass spectrometry (PSMS) has been developed and commercialized for analysis of fluid samples by mass spectrometry. PSMS provides advantages over existing analysis techniques by reducing sample preparation needs and incorporating the sample storage and sample introduction to a single consumable device that is disposed after analysis, thus eliminating cross contamination and/or cleaning ...

We propose to research and develop Flexible and Live Adaptive Training Tools (FLATT) as a flexible user interface capability within a generalized framework that can be applied to a wide variety of training instances. We plan to leverage our Generalized Intelligent Framework for Tutoring (GIFT) toolset because it is a flexible, expandable, service-oriented architecture (SOA)-based system that provi ...

The objective of this effort is to develop and demonstrate an intelligent, autonomous dc-ac distribution unit based on isolated power conversion technologies to support interconnection of dc sources and energy storage devices with an ac tactical microgrid featuring tactical power generation and load equipment. The unit specifically targets 60 kW, bi-directional power conversion and power/energy ma ...

The development of pulsed Long-Wave Infrared (LWIR) Quantum Cascade Lasers (QCLs) delivering pulse average optical power exceeding 10W in a nearly Gaussian output beam (M2 < 1.3) with wallplug efficiency exceeding 20% is proposed. Pulse width and duty cycle for fully packaged devices to be delivered to Army will be adjustable and their maximum values will exceed 700ns and 7%, respectively. The new ...

This proposal uses a novel architecture to build a heat exchanger that vehicle heat rejection by 5% while maintaining the same space claim and pressure drop as legacy systems. The novel design results in a substantial decrease in the pressure drop and an increase in thermal performance relative to state-of-the-art configurations. Conventional high volume component production methods will be combin ...

Military fuels such as JP-8, Jet A, and F-24 have lower lubrication properties than common diesel fuel. The direct injection fuel systems in vehicles designed to run on diesel can wear out prematurely due to lack of lubrication in these low lubricity fuel applications. The proposed solution minimizes component wear for selected vehicle applications.
