The main objective of this project is to develop technologies for variable speaking speed synthesis, or Text-to-Speech (TTS). A TTS system converts written text into spoken language. There are numerous commercial TTS systems; however, most systems do not allow for speed control of the output speech. In the simulation-based virtual training system, TTS systems are used to generate the voice of the ...

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 overall objective of this Phase II program is to continue and finalize the development of the dropsonde satellite data transmission device and back-end data retrieval system. This design and development effort will yield a number of prototype units to be integrated with the Yankee Environmental Systems dropsonde being developed concurrently. The combined device will be a more automated system ...

Bridger Photonics (BP) and collaborative partner Montana State University (MSU) propose to develop a completely novel, non-mechanical scanning mechanism that will enable a compact, high-resolution, imaging LADAR system for enhanced navigation aid during helicopter brownouts. Such systems are becoming prominent in today’s modernized military especially as the cost in lives and dollars has come to ...

We propose the development of a compact broadband underwater cylindrical transducers with integrated tuning networks and power amplifiers for Mobile Acoustic Counter Measures. There is a need for cost effective transducers that are broadband and have broad-beam coverage. BTech has designed and built improved counter measure transducers as well as acoustic modem transducers using both PZT materials ...
