An Energy Graph-Based Approach to Fault Diagnosis of a Transcritical CO2 Heat Pump
The objective of this paper is to describe an energy-based approach to visualize, identify, and monitor faults that may occur in a water-to-water transcritical CO 2 heat pump system. A representation using energy attributes allows the abstraction

An Exploratory Study of Field Failures [PDF]
Field failures, that is, failures caused by faults that escape the testing phase leading to failures in the field, are unavoidable. Improving verification and validation activities before deployment can identify and timely remove many but not all faults,

An Analytical Comparison of Some Rule-Learning Programs [PDF]
To become a mature science, Artificial Intelligence needs more theoretical work. One form this should take is the analytic comparison of existing programs to extract precise techniques from the code, compare similar techniques, expose faults, and extend ...

A Rough Set Approach of Mechanical Fault Diagnosis for Five-Plunger Pump
Five-plunger pumps are widely used in oil field to recover petroleum due to their reliability and relatively low cost. Petroleum production is, to a great extent, dependent upon the running condition of the pumps.

Transient Voltage Unit Protection Based on Fault Information Fusion
Transient protection has the advantage of ultra-fast operation. However, traditional transient protection is susceptible to the influences of transitional resistance and the initial fault angle, resulting in issues with sensitivity and reliability under ...
