Uncertainty quantification (UQ) can be performed with existing MDA M&S tools if efficient algorithms are developed and deployed. OptTek proposes to explore innovative methods and algorithms to 1) quantify output variation from all input uncertainties providing distributional information and extreme value identification, 2) isolate output variation from individual input uncertainties and from input ...

Septic shock is a significant worldwide health problem that affects millions, but is complicated to treat since many of the signs and symptoms are non-specific and common to other non-infectious sources of systemic shock. Patient care would be improved by a rapid test to monitor key biomarkers and determine whether antibiotic use is appropriate. We propose to deliver a quantitative, multiplexed ...

Rapid design and prototyping of systems and components needed by the DoD include the need for accurate models of non-linear and time-dependent magnetic circuit components, that provide advanced circuit capabilities for improved communications and remote sensing applications. Simulation of circuits using RF computational engines work well in the linear regime, but are inaccurate for non-linear and ...

Future, large footprint weapon systems can benefit from inexpensive telemetry collection assets that could be easily and quickly deployed in open-ocean and could either store the data for later pickup, or retransmit the data either on command from shore or autonomously. A low-cost telemetry collection system on buoys would enable development, testing, and evaluation of new weapon systems using rea ...

DARPA has embarked on the Experimental Spaceplane (XS-1) program to facilitate rapid insertion of smallsat payloads at aircraft-like operational tempos. An enabling technology for minimizing the cost and maximizing the payload-to-space capability of XS-1is reusable, all-composite, liner-less (Type V) cryogenic tanks with very low mass fractions. DARPA has identified that current material limitat ...

We propose a novel and promising solution for automated real-time audio authentication to combat vishing attacks. We first propose detailed solutions for different types of audio attacks, such as impersonators, spliced audio, pre-recordings, disguised, o...

Recent advances in Artificial Intelligence (AI) and computing power provide new opportunities to better organize and exploit large volumes of stored data residing in an organizations archives. State-of-the-art filing systems produce search results tha...

Traveling Wave Tubes (TWTs) were developed in the 1940s and are still a very popular RF amplifier device today.Yet, many TWT technologist have prophesized the end of the TWT market as new solid state RF devices emerge. Fortunately, continuous improveme...

In solid-state, a transistor-based concept is inherently transit-time limited. Transistors are already working with gate dimensions of 10s of nm and the saturation velocity of electrons in semiconductors is not going to exceed 107 – 108 cm/s, so there is no room to improve performance on a fundamental level. In VE devices, the diminished electron beam associated with scaling to small interaction ...

Heureka and DigitalGlobe propose exciting innovations to leverage commercial and public satellite imagery for national security uses. We will conduct one of the world’s largest machine learning experiments ever attempted with submeter or very high reso...
