There is an increased need for high-power UHF microwave amplifiers for scientific, medical, industrial, broadcast and military applications with improved overall efficiency- Existing amplifier technology can provide up to a megawatt of power with electronic efficiencies in the range from 65% to 70% for a single amplifier, and in some special cases efficiencies in the mid 70% range- However the pow ...

In general, HPC systems should not be used to carry out cybercrimes or execute improper jobs- Existing fingerprinting-based solutions can be used to understand what are running on HPC systems, but they typically are reactive, require system-wide data collection and processing, and do not consider adversarial scenarios- Hence, it is essential to build offline code analysis tools that can provide fi ...

One of the major hurdles to the commercialization of OLED lighting technology is its low light extraction efficiency when compared to inorganic LEDs- Currently only ~ 30% of the light produced by the OLED can be extracted- In order to be considered as a commercially viable option, OLED efficacy has to improve dramatically- The mismatch between the refractive indices among the active layer, transpa ...

Secondary Ion Mass Spectrometry (SIMS) is an important tool in the study of nanoscale composition of biological materials- For example, nanoscale SIMS has been used successfully to study important processes for bioenergy, such as nutrient transport in the rhizosphere, structural characterization of cell walls, and metabolic pathways in complex systems- Researchers use SIMS to collect high-spatial- ...

It has been observed that cyber-attacks are increasing in both prevalence and sophistication. Most existing cyber defense systems are still using the aged signature-matching techniques which can be easily avoided by current malware through polymorphic methods, such as obfuscation. In this effort, IAI proposes to develop DeepDefense, a deep-learning based cyber defense system to effectively detect ...

iNovex offers a practical approach to transition traditional engineering processes focused on controlling the documentation about systems, to a digitized shared reasoning environment focused on models of complex systems of systems.Our approach supports the Digital Thread's Authoritative Truth by applying semantic technologies to link disparate data sources and engineering artifacts across the acqu ...

WW Technology Groups (WWTG) proposed effort provides a scalable and powerful framework and foundation for Model Based System Engineering (MBSE) of Big Data (BD) with a software toolchain.The approach uses an established front end to perform the connection to data storage and flow of information that can consume a wide variety of data types and formats found in engineering documents.A series of BD ...

This is a prototype system that will take raw observation data, detect and characterize maneuvers, and use reinforcement learning to understand and react to evasive RSO behaviors in near real time. This will provide a framework to evaluate autonomous behavior strategies, such a safety, effectiveness, and robustness to manipulation. This work will enable surveillance operators to distinguish betwee ...

Space superiority requires space protection and space situational awareness (SSA), which rely on rapid and accurate space object behavioral and operational intent discovery. The focus of this project is to develop a stochastic approach for rapid discovery of evasive satellite behaviors. Designing the innovative decision support tool has numerous challenges: (i) partial observable actions; (ii) eva ...
