Machine diagnostic system and method for vibration analysis

A diagnostic system includes a vibration sensor mounted on a machine to measure vibrations. Vibration signals from the sensor are processed and analyzed by the system. From a known critical frequency of a vibration-generating component, the system measures the amplitude of the vibration signal at more than one harmonic frequency of the known critical frequency and compares the amplitudes to amplitudes at adjacent harmonic frequencies. When a relatively large amplitude is found at a harmonic frequency, that is a harmonic frequency near a resonant frequency of the physical path between the vibration sensor and the vibration-generating component, the system analyzes the shape and magnitude of the vibration signal around that harmonic frequency to evaluate the condition of the machine.

Agent-Based control of a municipal water system

In this project, we discuss the implementation of an intelligent agent- system for controlling a municipal water system. This work presents an agent-based approach to establishing the expected water requirements, operating constraints, and evaluation criteria and the use of collaborating agents to prescribe an optimal control scheme. A distributed control strategy is implemented and evaluated in a simulation of a municipal water system.

Cost-based dynamic reconfiguration system for intelligent agent negotiation

Autonomous, highly distributed control architectures are composed of a significant number of agents that can reason and act on behalf of represented processes or artifacts in a coordinated manner. Depending on the social organization capabilities of the agents, the autonomous system could evolve into complex agent organizations called temporal holarchies. Cost-based negotiation supports the holarchy formation. Dynamic hierarchical teamworks architecture of middle-agents is described to increase robustness of the architecture.
