Through previous grant awards from IES, researchers developed Graspable Math, a tablet-based intervention where middle and high school students create and manipulate complex expressions for basic operations as well as equations and equations systems and inequalities. In this project, the team will develop a prototype of Graspable Math Activities, an app with novel kinds of algebra practice and ass ...

In the latter half of the 20th century, microprocessors faithfully adhered to Moore’s law, the well-known formulation of exponentially improving performance. As Gordon Moore originally predicted in 1965, the density of transistors, clock speed, and power efficiency in microprocessors doubled approximately every 18 months for most of the past 60 years. Yet this trend began to languish over the la ...

GeoComposites, LLC, aims to develop the next generation of high performance fiber reinforced composite feedstock for in-space manufacturing of high strength parts via fused deposition modeling (FDM). Since plastics are inherently low in strength, additive manufactured plastic currently cannot compete with metallic parts. Failed parts on the International Space Station (ISS) and the genuine need fo ...

C-Suite Services, LLC (C-Suite) will produce at least one manufacture-ready, full-scale design for the licensed technology of the Balanced Floating Piston Valve. This design is intended as a “drop-in” replacement for an existing valve used in rocket engine component testing. The operating environment, pressures to 15,000 psi and flow rates of 1,000 lbm/sec of Gaseous Nitrogen, have proved prob ...

A receiver system for use in LIDAR consisting of an optical filter and optical spectrometer based upon two-photon absorption is proposed. The filter and spectrometer both use dispersion from excited state transitions of atomic rubidium to create a birefringent medium. The birefringent medium of the optical filter rotates the polarization of light so that it is transmitted through crossed polariz ...

The nondestructivecharacterization of advanced composites, such ascarbon-fiber reinforced polymers (cfrp), by electromagnetic means iswell established [6]-[24]. What isneeded to advance the state of the art are sophisticated inversionalgorithms that allow layup and impact damage to be determined inlocalized regions, which means that the more traditional methods ofmodel-based inverse methods must ...

According to the decadal report titled, Life and Physical Sciences Research for a New Era of Space Exploration, a Report, "...the AHB Panel would be remiss if it did not strongly recommend an animal centrifuge capable of accommodating rats/mice at variable gravity levels." Furthermore, the panel stated, “...research on animal models will be constrained without the ability to manipulate the gravi ...

PCKA is partnering with researchers at Purdue University to develop an Autonomous Power Controller (APC) for mission-critical microgrids to supply electric power in a highly autonomous and secure manner to accomplish mission objectives. The APC consists of a centralized controller connected to an array of local component controllers. The centralized controller will be capable of optimal generation ...

TECHNICAL ABSTRACT: Gliders alone are incapable of monitoring the shallower regions of the hypoxic zone under conditions when the density gradient is strong, therefore surface vehicles are required to autonomously collect a suite of oceanographic observations from surface waters and profile this portion of the hypoxic zone. Autonomous Surface Vehicles, LLC (ASV, LLC) is partnering with Integral Co ...
