Purpose: In prior research and development, the project team developed Storyworld, a web-based activity with mini-games to support English Learners (EL) in language acquisition. In this project, the team will fully develop and test a formative assessment dashboard that provides teachers with insights into EL student's progress as they use Storyworld. ELs are the fastest-growing student population ...

Purpose: This project team will fully develop and test Woot Math Polls, a formative assessment dashboard that converts student math work into data-driven insights to inform teacher instruction and student learning in middle and high school algebra classrooms. Research has marked a decline in math achievement around the time students take algebra in middle school. Technological innovations that pro ...

Purpose: The project team will fully develop and test CloudLab, a web-based dashboard to present scientific data captured by sensors during experiments. The Next Generation Science Standards (NGSS) emphasize the actual doing of STEM so that students can apply learning to the real world. However, students often have difficulty collecting, measuring, and applying data from inquiry activities to furt ...

Purpose: This project team will fully develop and test Mission US TimeSnap, a game integrated within a Virtual Reality (VR) headset. This VR environment will provide an immersive exploration and analysis of events in U.S. history. In the most recent National Assessment of Educational Progress, only 17% of grade 8 students performed at or above the proficient level in U.S. history. The discipline o ...

Next-generation high-performance computing (HPC) hardware, such as the Intel Xeon Phi Knights Landing Many-Integrated-Core processor, provide new deep memory architectures that offer the promise of increased performance. The challenge in taking full advantage of this architecture is selecting which data structures will be placed in the high-bandwidth memory. Optimizing data structure placement in ...

DTRA uses High Fidelity Computer Codes (HFCC) to investigate weapon effects and techniques for countering Weapons of Mass Destruction (WMD). End-to-end HFCC simulations in support of the DTRA Agent Defeat Warfighter Capability will require calculations including multiple phenomena that occur in vastly different time scales (-sec to hours). As DTRA becomes increasingly reliant on computational mode ...

In response to SBIR Topic DTRA172-006, Welkin Sciences proposes to design and build a new all-digital fading channel simulator to be called CoLTSAD. This new simulator design will be the latest addition to our family of Configurable Link Test Sets (CoLTS). It will be capable of emulating the full range of MIL-STD-3053 scintillating channel conditions for all SATCOM frequency bands up to Ka-band. C ...

During Phase I and a first Phase II, Welkin Sciences developed the Channel Realization Generator (CReG) algorithm, an enhanced functional replacement for the ACIRF code intended to be embedded into software link simulations and HWIL fading channel simulators. The proposed second Phase II effort will refine the CReG documentation and its software and firmware implementations. Many in the strategic ...

Our objective is to develop and demonstrate an integrated capability to perform dynamic retasking of enterprise wide management of OPIR, radar, and other operationally relevant sensors. The goals of this effort are to refine our existing OPIR tasking approach and to develop and Enterprise SRM approach that will allow the C2BMC to achieve the earliest possible launch detection and maintain the high ...

Under this Phase II SBIR effort Welkin Sciences will design and implement a Jammer Emulator hosted on the MDA sponsored CoLTS-LC hardware platform, originally built for nuclear-effects channel simulation.The Jammer Emulator will support emulation of a wide range of jamming methods, including frequency-following, which is not readily implemented using standard commercial test equipment.A remote int ...
