Award Data

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 ...

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 ...
