This paper proposes a methodology to deal with the fault section estimation problem in electrical power systems. The main motivation for this study lies in the fact that operators of control centers usually are subject to information overload during great contingencies. The fault diagnosis is formulated as an optimization problem and solved through two stages: classification of events at equipm...

An interactive surface editing framework that is well suited to the needs of geophysical modelers and interpreters is described. This surface editing framework allows a non-expert user to quickly create complicated surfaces by combining two simple concepts: deformation and cutting. Deformations change the geometry of a surface and allow a user to model continuous geologic horizons. Cutting chan...

A method for power systems alarm handling and fault location is presented. The method employs artificial neural network classifiers whose inputs are alarms from relays and circuit breakers operation, while the outputs identify the faulted system component. Fault location is determined even in cases of protection system failures or in the presence of noisy data. The employed methodology is illus...

Ideally, health monitoring of new, complex engineering systems should occur from initial operation to decommissioning. Health monitoring typically involves a suite of modules, including system monitoring, fault detection, fault diagnostics, and system prognostics. However, for systems which have not yet operated, this is challenging. Most available health monitoring modules are empirically base...
