Through previous research and development, the team created a teacher platform that suggests research-based strategies for supporting students with special needs or targeted skill gaps. This project will develop a prototype of a dashboard for teachers to create, access, and track student's Individual Educational Plans (IEPs). At the end of Phase I, in a pilot study with six middle school special e ...

Through a previous grant award from the U.S. Department of Education, researchers developed Read for Success, an intervention designed to stem the summer slide among struggling readers. This project will develop a prototype of Mix Libris, an Augmented Reality (AR) enhanced mobile literacy platform designed to support and motivate grade 3 students in acquiring and improving literacy skills. Mix Lib ...

Through previous grant awards from IES and the National Science Foundation and an ED/IES SBIR award, researchers developed a virtual laboratory with performance-based simulations aligned to Next Generation Science Standards (NGSS) in physical, life, and earth science for middle school, as well as a dashboard to provide teachers real-time formative and summative assessment reports on students doing ...

Threaded fastening systems in vibrating environments require a secondary locking feature, augmenting primary locking provided by an applied preload, to prevent vibration-induced loosening. The secondary locking feature can be mechanical, prevailing torque-type, or an adhesive. Self-locking nutplates and inserts are often more expensive than adhesives, require retorquing or on-torque adjustments, a ...

Over many data collection campaigns, a large number of propulsion related signature events have been observed across an extended range of the electromagnetic spectrum. The current suite of plume modeling tools contains the basic framework for flowfield and signature generation, but lacks the underlying physical mechanisms and supporting property databases to properly account for alternate waveband ...

Physical Sciences Inc. has successfully demonstrated the operational capability of a filament wound composite case designed to mitigate against slow cook-off, fast cook-off, bullet and fragment impact threats for solid rocket motor (SRM) systems. The implemented manufacturing, quality control and assurance processes enable production of small and large diameter motors to satisfy strategic and tact ...

We intend to dramatically improve the performance of the Standardized Atmosphere Generator (SAG), an environmental background model used to characterize the atmospheric state.SAG is an empirical model which creates a complete picture of the atmospheric state for electro-optical/infrared (EO/IR) and radar (RF) systems as well as trajectory computations for targeting and tracking.These systems requi ...

Missile Defense Agency (MDA) Model and Simulation (M&S) capabilities include Core Truth models (CTM) capable of simulating all physics governing missile detection, tracking and intercept events. A key component of the simulation tools is an accurate and fast atmospheric radiation model to describe the target signals as they propagate through the atmosphere to the sensor. Ideally, such a model shou ...

The flight environment conditions encountered by re-entry vehicles (RVs) and RV associated spent boosters and flight hardware can produce complex wakes that are difficult to model.Under such high dynamic pressure and angle-of-attack (HDAOA) conditions, ablating heat shield material is entrained in the flow in the form of gases and particulates and reactive chemistry between atmospheric and ablatin ...

Physical Sciences Inc. (PSI) proposes to utilize a ground-based simulation facility based upon its patented FAST technology to obtain critical data necessary to validate and extend the capabilities of the MDAs high altitude plume code, SOCRATES-P, to model plume signatures with high fidelity.In Phase I PSI demonstrated the model validation approach by measuring the velocity dependent cross section ...
