A key technology with immediate potential for reduction of greenhouse gas (GHG) emissions associated with fossil fuel power plants is carbon sequestration. To ensure successful CO2 sequestration, the ability to monitor leakage from the geologic storage sites and the pipelines delivering the CO2 to those sites is paramount. The goal of this SBIR is to accelerate the development of a low-cost fiber- ...

This proposal details an ambitious effort to develop Hybrid Phishing Protection System (HPPS). HPPS is a novel heuristics-based protection system that employs three lines of defenses to provide automatic, high-accuracy, and low-latency phishing identifica

This proposal details an ambitious effort to develop Smart Host-Based Intrusion Detection System (SHIDS). The SHIDS supports self-healing, self-monitoring, self-diagnosing, self-hardening, and self-recovering network architecture after corruption by an attack by automatically creating malware fingerprints and alert messages to protect against variants of known threats as well as possible zero day ...

The methods that has been historically developed and fielded for alarm and fault management in traditional communications networks do not provide adequate operational assurance for complex ad hoc tactical networks, especially for unskilled and inadequately trained operational personnel. Work on tactical network operations management that is proposed under A09-150 will use a novel approach that int ...

Multi-channel array manifolds are required for wideband AESA applications. In modern solid-state AESA arrays, MMIC-based T/R modules generally utilize digitally-controlled phased shifters to steer the beam on transmit and receive. The given phase value is only accurate at one frequency, and so for wide bandwidths of several hundred MHz (at X-band for example), the beam does not get formed properly ...

Key obstacles to extending OFDM to wireless links and networks at high-frequencies and dynamic channels are inherent low performance to Doppler and power amplifiers operation with high back-off. Other significant obstacles are multipath and impulsive noise. PEARL-OFDM combines a layered architecture with technologies that mitigate such obstacles and enable full-range rates that maximizes connectiv ...

Aria Microwave System Inc. (AMS) will develop a lightweight, compact, scalable DEW system with 60% - 90% DC-to-RF efficiency. Examples of an S-Band concept system show that lethality levels > 1 W/cm ^2 at 100 meters can be attained with DC power in 10’s of kW, 10% duty cycle. The system uses AMS’s proprietary solid state, compact, lightweight, high efficiency, high power, active cavity amplifi ...

The design and development of piezocrystal sonar transducers is a challenging multidisciplinary and technological effort that spans many fields and skill sets. We look to extend and improve our transducer assembly technologies to reduce cost and implementation time for sonar technology transition and in particular our methods for Active-Passive single crystal ring development and fiber glass wrapp ...

Current comprehensive rotorcraft analyses typically use lifting line theories coupled with 2D look-up tables to determine rotor blade lift, drag and pitching moment. These methods cannot directly capture 3D flow effects that influence the aerodynamic characteristics of advanced planforms, complex tip-shapes and low aspect ratio wing/tail surfaces. CFD codes have been coupled to comprehensive codes ...

Enhancing rotorcraft safety due to engine or drive train failures has been a primary concern throughout the history of vertical flight operations. Recent work on autorotation trajectory optimization has shown potential for improved flight control and guidance solutions, but work remains to implement these solutions without over-burdening the pilot during this high workload flight condition. With t ...
