ABSTRACT:Unwanted RFI is a growing concern due to the ever expanding RF world around us. Not only are the number of RFI sources increasing, so too is the frequency usage across the RF spectrum. As a result, RF systems, like the AFSCN, are expected to become more susceptible to disruptions in coverage and service. Additionally, these systems must maintain a small RF footprint and not contribute to ...

ABSTRACT:There is interest in developing an electronically controllable variable transmittance for fixed wing visor applications. Guest-host liquid crystal technology developed by AlphaMicron, namely e-Tint, has demonstrated the ability to meet the optical requirements for this application. However, implementation on large area, complex curve visors has not been attempted.AlphaMicron proposes to i ...

ABSTRACT:Quantitative ablation recession rate measurements of heat shield surfaces are essential for evaluating the performance of heat shield materials. Currently, these measurements are limited to two-dimensional images that focus on the nose tip regression rate. For wedge testing, recession rate is determined by comparing pre- and post-test measurements, and therefore, recession rate as a funct ...

ABSTRACT: SIFT's Phase 2 Hy-CIRCA proposal builds on progress in Phase 1 to address the challenge of effectively, reliably, and safely tasking cooperating teams of autonomous cyber-physical systems (CPSs). SIFT's Playbook(tm) interface approach provides high-level, goal-based tasking for multi-agent autonomous missions. SIFT's Cooperative Intelligent Real-Time Control Architecture (CIRCA) automa ...

ABSTRACT: Researchers are identifying new biomarkers to help monitor, diagnose, and treat growing threats to the human body and enhance human performance. Recent sensor work combining biorecognition elements with field effect transistors (bio-FETs) has been shown sensitive and selective to biomarkers in the picomolar range with continuous detection; however device-to-device performance variability ...

ABSTRACT: Sleep deprivation, exercise, or continuous mental tasking are fatigue-related contributors in DoD mishaps. Therefore, a critical need exists for fatigue detection technologies which are real-time, non-invasive, compact, portable, and accurate to aid decisions to replace or rest an individual as a preventative measure. Certain compounds in human breath have been linked to disease states ...

Achieving cyber security has been problematic given the general lack of foundational quantitative metrics to gauge the advantages of one security solution over another. This work significantly advances the development of quantitative metrics and the sec...

By incorporating microwave plasmas at ambient pressure—higher than can normally be accomplished for materials reactors—highly reactive plasmas will be used to process carbon nanomaterials at a two orders of magnitude higher reaction rate than previously accomplished. The result is a vastly simpler, ecologically cleaner process suitable for competing head-to-head costs with carbon black. Becaus ...

High-average current high-quality electron beams are imperative for high-power RF accelerators used in various energy and environmental applications in industry, medicine, and national security as well as for advanced existing and future accelerator systems such as PIP II, particle colliders (eRHIC BNL) for cooling high-energy proton, ion, and hadron beams, storage rings, wakefield accelerators (A ...

The ages of men have been defined by the materials that make up the tools we use, from the ancient stone and iron ages to the modern nuclear and silicon ages. Over these ages, man’s knowledge has been built upon previous observations. The base of this materials knowledge is understanding the relationships between structure- processing-properties-performance. The top of this pyramid is systematic ...
