Fault detection, isolation, and recovery (FDIR) is a subfield of control engineering which concerns itself with monitoring a system, identifying when a fault has occurred, and pinpointing the type of fault and its location. Two approaches can be distinguished: A direct pattern recognition of sensor readings that indicate a fault and an analysis ...
Example of the application of identifying geological structures and rock contacts using aerial photographs. The black dash lines refer to some local faults which are determined according to the photo-lineaments. The yellow area is the deposits. The pale blue area is volcanic rock. The blue area (bottom right) is rhyolite. The pink area is granite.
San Andreas Fault System (Banning fault, Mission Creek fault, South Pass fault, San Jacinto fault, Elsinore fault) 1300: California, United States: Dextral strike-slip: Active: 1906 San Francisco (M7.7 to 8.25), 1989 Loma Prieta (M6.9) San Ramón Fault: Chile: Thrust fault: Sawtooth Fault: Idaho, United States: Normal fault: Seattle Fault ...
A fault plane is the plane that represents the fracture surface of a fault. A fault trace or fault line is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. [3] [4] A fault zone is a cluster of parallel faults.
Faults that do not trigger a sustained requirement for fault isolation and fault recovery actions should not be displayed for management action. For example, lighting up a fault indicator in situations if human intervention is not required induces breakage by causing maintenance personnel to perform work when nothing is already broken.
A simulation of a plausible major southern San Andreas fault earthquake — a magnitude 7.8 that begins near the Mexican border along the fault plane and unzips all the way to L.A. County's ...
A fault tree diagram. Fault tree analysis (FTA) is a type of failure analysis in which an undesired state of a system is examined. This analysis method is mainly used in safety engineering and reliability engineering to understand how systems can fail, to identify the best ways to reduce risk and to determine (or get a feeling for) event rates of a safety accident or a particular system level ...
Before detailed analysis takes place, ground rules and assumptions are usually defined and agreed to. This might include, for example: Standardized mission profile with specific fixed duration mission phases; Sources for failure rate and failure mode data; Fault detection coverage that system built-in test will realize
