  • Instrumented Safety: The right balance

    The different functional safety guides and standards such as IEC61508/511, which impose formal schemes for the safety instrumented functions (SIF), have brought significant safety gains to the process industry over the last 30 years. Still, we can observe a drift in the application of those standards, which often leads to increased costs, loss of operability, and, more worrying, a false ...

  • Intrusion detection through SCADA systems using fuzzy logic-based state estimation methods

    Supervisory Control And Data Acquisition (SCADA) systems represent a vulnerability in vital infrastructures. For example, an electric power system is subjected to intrusions via its SCADA systems; however, the instrumentation provides detectable variations in response to such interference. Presented herein is a strategy that augments state estimation methods using a Hybrid Fuzzy System for fault ...

  • Use of Electromagnetic Induction Tools in salinity assessment/appraisals in eastern Colorado

    Abstract Electromagnetic induction (EMI) is a relatively low-cost and rapid method for measuring, assessing spatially soil salinity. The two studies were conducted to evaluate data obtained with a single-frequency (EM38 meter) and multi-frequency (GEM300 sensor) EMI instruments and to relate apparent conductivity measured by these instruments with the more conventional conductivity of the ...
