This proposal for Phase II in response to the Defense Threat Reduction Agency (DTRA) topic 212-006 “Algorithm that can locally link radiation detectors (of different resolutions) to enhance identification/ localization capability”. The topic describes the need for an algorithm to support the fusion of multiple and varied detector outputs into actionable information. The specific focus is to id ...

There is a growing need to accurately characterize nuclear materials not only for nuclear safeguards and nonproliferation treaty verification but also for forensics and provenance. At present, nuclear material identification requires samples to be collected and sent to laboratories for analysis using large and expensive equipment, such as inductively coupled plasma mass spectrometers (ICP-MS) or s ...

Welkin Sciences proposes investigating scintillation-hardening techniques applicable to DoD's strategic communication systems, focusing on hardening specific SATCOM links within the Ballistic Missile Defense System Communications Network that are of particular interest to DTRA and its customer, the Missile Defense Agency (MDA). These new scintillation-hardening techniques are based on computationa ...

We propose developing new instrumentation based on swept-wavelength external cavity quantum cascade lasers (swept-ECQCLs), to acquire physical/chemical data on chemical weapon agent (CWA) and simulant properties in laboratory-scale explosive testing, and to improve/validate computational fluid dynamics (CFD) codes. In Phase I, we demonstrated laboratory measurements of CWA simulant combustion usin ...

Welkin Sciences proposes to design and build a new fading channel simulator to be called the All-Digital Configu­rable Link Test Set (CoLTS–AD). It will be capable of emulating the full range of MIL-STD-3053 scintillating channel conditions needed to test all of DoD’s strategic communication systems. CoLTS–AD will support developmental and ac­ceptance testing of conventional communication ...

TDA Research, Inc. (TDA), designed, built, and tested a dense array of 100 very low cost infrasonic sensors. Due to their low cost (1/100x-1/10x the cost of other infrasound sensors), they can be economically deployed in very large numbers; such large arrays can gather more information than a few expensive sensors. They are sensitive from 0.1 Hz - 100 Hz down to 0.08 Pa. We tested the sensors in s ...

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 ...

Micro-RDC has developed portable radiation effects test structures that scale to new process nodes.These structures will enable the investigation of the effects of radiation on the new technology from the material processing level as well as the circuit level.Fabricating the chosen structures and the refinement of software to extract the model parameters will be completed in this effort.A suite of ...

Purpose: This project team will fully develop and test Fate and Fortune, an online class-wide intervention where grade 8 students learn algebra within a story-based game. Research demonstrates that students who do not succeed in algebra are more likely to eventually drop out of high school. When students begin Algebra I, a lack of conceptually meaning and understanding can be further reinforced by ...
