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 ...

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 ...

High resolution SAR imaging and Ground moving target indicator (GMTI) radar are of crucial to intelligence surveillance and reconnaissance operations. High resolution SAR imagery are often realized at the expense of wide bandwidth waveform, and to achieve long dwells over a wideband width, often the operating frequency band overlaps with other co-band radars, and it becomes necessary to notch out ...

Carbozyme will develop a novel closed circuit rebreathing apparatus based on biomimetic principals. Our objective is to catalyze the conversion of carbon dioxide to ionic equivalents that can be readily absorbed into seawater, eliminating gas bubbles. This design has the unique advantage of being able to operate continuously for the full duration of the oxygen supply. Installation of the rebreathe ...

Distributed fiber grating sensor technology is used to support the measurement of key blast wave parameters including position, velocity, pressure and temperature. The system will support and characterize existing propellants and explosives and be used to demonstrate the difference between materials that deflagrate and detonate.

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 ...
