Fault Detection and Diagnostics Using Data Mining
2014The purpose of data mining is to find new knowledge from databases in which complexity or the amount of data has so far been prohibitively large for human observation alone. Self-Organizing Map (SOM) is a special type of Artificial Neural Networks (ANNs) used in clustering, visualization and abstraction.

Diagnostic Test Generation for Transition Delay Faults Using Stuck-At Fault Detection Tools
Journal of Electronic Testing, 2014By adding a few logic gates and one or two modeling flip-flops to the circuit under test (CUT), we create a detection or diagnostic automatic test pattern generation (ATPG) model of transition delay faults usable by a conventional single stuck-at fault test pattern generator.

Creating an automated chiller fault detection and diagnostics tool using a data fault library
ISA Transactions, 2003Reliable, automated detection and diagnosis of abnormal behavior within vapor compression refrigeration cycle (VCRC) equipment is extremely desirable for equipment owners and operators. The specific type of VCRC equipment studied in this paper is a 70-ton helical rotary, air-cooled chiller.

Robust fault detection and isolation via a diagnostic observer
International Journal of Robust and Nonlinear Control, 2000Considering fault isolation and observer design methodologies, the objective is to achieve multiple and simultaneous fault isolation capabilities along with robustness to structural uncertainties through the design of a single diagnostic observer. The present approach is based on a complete solution of the disturbance decoupled fault detection observer

Fault Detection and Diagnostic System for an Industrial Refrigeration Installation
IFAC Proceedings Volumes, 1997Abstract This paper describes the application of quantitative model-based FDI to the refrigerator system a food processing plant. This represents a critical part of the plant from a maintenance cost point of view. The main system is a thermofluid process in which an ammonia thermodynamic process is used for cooling purposes.
