Vadum will continue improving MATCH (Multimodal AcousTic Characterization of Hoax calls), an innovative machine learning system that automatically monitors maritime Search and Rescue (SAR) VHF channel(s).Vadum showed feasibility for the system and developed key components in a six-month Phase I effort.In Phase II, Vadum will further develop and refine MATCH into a real-time prototype that continuo ...

Phase I proposes a workflow, called Masked Vulnerability-Preserving Reduced Order Model (MVP-ROM), that encodes a novel non-weaponizable structure-preserving ROM algorithm using a nonlinear port-Hamiltonian modeling for networked power systems, integrated under the Idaho National Laboratory (INL)’s All Hazards Analysis (AHA) Framework for Critical Infrastructure (CI) analysis. The project p ...

The current state of the art for production computational fluid dynamic (CFD) simulations in both the Entry, Descent and Landing (EDL) communities and modeling of hypersonic vehicles is the solution of steady-state problems on fixed computation grids. However, the majority of relevant challenge problems are unsteady. Accurate simulations of such unsteady phenomena currently require computational g ...

The proposed effort concerns technologies related to cryogenic propellant production, storage, transfer, and usage to support NASArsquo;s in-situ resource utilization (ISRU) goals. nbsp;They include a broad range of applications, scales, and environments consistent with future NASA missions to the Moon and Mars.nbsp;nbsp;More specifically, the project will addressnbsp;development of a piecewise-sm ...

Corvid Technologies (Corvid) and North Carolina State University (NCSU) are employing a novel moving Discontinuous Galerkin with Interface Conservation Enforcement (MDG+ICE) approach. The MDG+ICE method represents a fundamentally grounded and break-through approach and is specifically designed for flows with discontinuities and therefore especially attractive for hypersonic flows. During Phase I, ...

Achieving trustworthy and trusted autonomy starts early in the development process through performing hazard analysis, fault analysis, identifying mitigating requirements, and carefully and rigorously tracing those requirements all the way into design, models, implementation, and tests. However, traceability can be time-consuming, costly, and error-prone. To address these challenges, significant a ...

This Phase I SBIR will lead to the development of a bandwidth tailored pump source for high purity photon pair generation. Spontaneous parametric down conversion can be used to generate high purity photon pairs at wavelengths of interest to NASA and the broader scientific community. However, these sources are highly dependent on pulsed pump laser parameters. Traditional pulsed laser sources are la ...

This Phase II project aims to prototype a novel technology that can advance the state-of-the-art in high performance space computing.nbsp; The base computer technology, called ldquo;RadPCrdquo;, brings together a suite of fault recovery mechanisms that enable Commercial-off-the-Shelf (COTS) Field Programmable Gate Arrays (FPGAs) to operate reliably in the presence of space radiation that causes si ...

This project will advance technology for the automated assembly of large truss towers.nbsp; Assembly of truss-based structures is one of the leading candidates for establishing some of the early lunar infrastructure.nbsp; Specifically, joining technologies and robotic tools are required to enable autonomous/automated assembly of tall towers as well as shelters, domes and habitats.nbsp; Automated a ...

The proposed work aims to demonstrate significant improvement in AlGaN-based detectors and detector arrays by employing single crystal AlN substrates, which practically eliminates leakage induced by screw dislocations. By employing defect controlled APDs on single crystal AlN, we aim to demonstrate sensitivity over the whole UVC range (120 - 275 nm) while being solar and visible blind. We will pro ...
