In this proposal, we will develop a uniform framework, called a multimedia mediator, for integrating and querying multimedia data as well as heterogenous data located on a distributed network. The multimedia mediator will use distributed computing technology to scale up to real-world applications. We will develop graphical query languages and query engines whereby an end-user can query a system ...

AbTech will survey the hardware and software available to determine what capabilities should be included in a natural language understanding mission planning assistant. A language parsing and encoding system in ANN will be used to parse and encode ASCII outpuf resulting from a voice recognition system such as DragoDictate. The ASCII output from the voice recongnition system will go to the ANN la ...

Significant deficiencies exist in the laser source technology for IRCM, specifically in the limited pulse rep-rate capability, limited average power output and capability to be transitioned to field environments. We propose a diode pumped solid state Er,Ho:YSGG laser and optical parametric oscillator to resolve these deficiencies. This laser has a potential dual use market in micro-surgery where t ...

With new detectors capable of sensing 7.5 - 9 micron wavelengths, a future threat is emerging since these detectors can be used in seekers. The need is to counter this threat with a laser source operating at 7.5 - 9 microns. The source requirements are 5 - 10 Watts of average power and a repetition rate of > 10 kHz. The proposed laser source is a Nd:YAG-pumped tandem OPO system consisting o ...

For future long-range theater ballistic missile defense, aircraft-mounted LADAR systems require eyesafe laser transmitters that produce higher pulse energy and better beam quality than currently available optical parametric oscillators (OPOs) pumped by diode-pumped Nd:YAG lasers. Aculight proposes a novel laser transmitter approach that can simultaneously generate the required pulse energy, b ...

A discrete event computer simulation will be developed and used to evaluate the expected performance of the UHF satellite communications Automatic Demand Assignment Multiple Access (Auto-DAMA) Subsystem. Phase I will describe UHF DAMA traffic scenarios, define design requirements for the Auto-DAMA computer model and develop a model of fundamental , single channel Auto-DAMA operations. Phase II wil ...

A stratified random sampling technique is used to minimize the time until detection of users of illicit drugs. The stratification is based on likelihood of drug use and importance of the billet occupied. Likelihood of drug used is calculated from fundamental characteristics (e.g., age, sex, education), performance, health and behavior (e.g., relative amount of sick leave, unusual behavior) ...
