We shall develop a dynamic agent web architecture and software prototype that builds on top of COTS database integration technology to deliver view management and data mining services.The data mining services shall consist of case based reasoning and association. We shall use case based reasoning and association agents in identifying new links and relationships within data contain in shipboar ...

In today's military environment ships, systems, and equipment are being asked to perform at levels not thought possible a decade ago. The intent is to improve process operations and equipment reliability, availability, and maintainability without costly upgrades. Of course, these gains must be achieved without impacting combat readiness. Downsizing is also taking its toll on operations. Loss o ...

The ultimate goal of the proposed R&D is to design, develop and validate innovative CORBA-based software security services and compatible hardware architectures which provide high assurance for multi-level secure (MLS) network applications. The proposed approach is innovative in that it is based on the emerging OMG Security Services Specification (SSS) plus a proprietary technique for maintaining ...

One of the most important applications of mid-caliber (5-inch) Naval guns is in meeting the defensive requirements of the Close-In-Weapon-System (CIWS). The function of the CIWS is to engage and defeat aircraft and cruise missile threats that have avoided or survived the extended area defenses. AMELEX offers to explore combining a guidance and control/divert system with a radar or IR seeker in the ...

Airborne SAR systems currently exist and are used for wide-area surveillance and ground mapping. The majority of deployed systems have frequencies (400 MHz-30 GHz) which, in most cases, cannot penetrate the soil to the depth required for detection of buried mines and unexploded ordnance. Lower frequencies are required for penetration of the ground. However, in the lower parts of the frequency spec ...

The LCAC Full-Mission Trainer (FMT) is providing a cost-effective tool for training LCAC operators in normal craft operation and casualty mode conditions. However, the FMT was never validated with full-scale LCAC test data. Rather, the feel of the FMT was uning coefficients in response to inputs obtained from experienced LCAC operators. The FMT training schedule combined wi ...

Shipboard electrical casualty faults can produce destructive voltage transients and outages that impair ship capacity for casualty fight through. Recent work on relay algorithms to detect faults and coordinate multiple circuit protection devices (CPDs) has demonstrated high-speed relay algorithms capable of reliably detecting transient events within several microseconds of their occurrence. These ...

State-of-the-art real-time diagnostic systems generally consist of two integrated components: fault detection and fault classification (isolation) systems. Although such systems may be able to recognize failure precursors, they have no mechanism for exploiting diagnostic information for prognostic purposes, i.e., for predicting the time to machinery failure. Prognostic information is critical as i ...

Many modern systems rely on multiple innovative actuators and effectors to improve performance, versatility, and survivability. In systems where several actuators or actuator combinations are capable of affecting the behavior of a single controlled varaible, an opportunity exists to incorporate non-traditional features in the control law, including post-failure reconfiguration and optimi ...

Autonomous control of uninhabited air vehicles (UAVs) presents a number of challenges, including detecting failures across the entire flight regime/mission envelope, differentiating between behavioral changes due to failures and those due to uncertainties, real-time control law redesign, and real-time modification of UAV trajectories and sensor-allocation strategies.
