This paper describes two procedures for automatic monitoring of control loop performance. The first is a procedure for detecting oscillations in control loops, and the second a procedure for detecting sluggish control loops. The focus of the paper is the industrial application of the procedures, and the various implementations possible and available.

The maintenance management plays an important role in the monitoring of business activities. It ensures a certain level of services in industrial systems by improving the ability to function in accordance with prescribed procedures. This has a decisive impact on the performance of these systems in terms of operational efficiency, reliability and associated intervention costs. To support the mai...

In various industrial fields, the operators use predesigned procedures either to solve problems or for troubleshooting. In the Parisian subway, such procedures exist since 1900. However, these procedures are not always exactly suited to the case at hand, and the operators generally prefer to customize a solution than to rely on fixed procedures. For the design of an “intelligent” assistant syst...

The ability to analyze security breaches in industrial control systems (ICS) is vital for the fast remediation of compromises and thereby helps to improve the robustness of these systems in the face of attacks. Current forensic practice lacks specific tools and procedures for performing investigations in these environments. Furthermore, the specifics of industrial control systems in most cases ...

Image processing in industrial vision systems requires both real-time speed and robustness. Modern computers, which fulfill the first demand, are sensitive to hard industrial environment conditions and require considerable amounts of energy. Programmable logic chips are available, which can realize many simple, still time-consuming operations in a parallel or a pipelined manner. The paper discu...

Oxysterols are products of enzymatic and/or chemical cholesterol oxidation. Their measurement during and after a milk production chain could represent useful tool to monitor increase the commercial nutritional value milk.

The present study describes a model which, by using pattern recognition procedures, detects defects on the external surface of pieces and industrial products, especially those whose borders are indefinite. In addition to describing the model, a practical application and the results obtained are described, including an important extension of this work, i.e. the comparison of pieces with standard...
