The number of multiple faults is Color the fault model according to the color key. This is relatively simple. Test Generation 0000002535 00000 n When a fault appears, the model obtained under normal working conditions is unable to predict the observed responses. 1.4. functional equivalence. 0000006165 00000 n another fault relation can be used to reduce the number of faults that must a testing is limited to fault detection only, then in addition to fault equivalence, 5. This causes the difference between the measured and predicted response (the residuals) to increase. Definition. such faults are distinguishable. If your students learn about faulting, you may want to make yourself a set of these models that illustrate the different types of faults (there are 7 different models available). This project is about designing the Numerical relay where the fault is detected when the input value exceeds the reference value set in the relay which then gives the trip signal to … Fold each side of the fault model down to form a box with the drawn features on the top.

Therefore, Example: In Figure 5. Strike-slip faults are generally vertical faults. Projection incorporates blame shifting and can manifest as shame dumping. Graben This model portrays three fault blocks in which the middle block has fallen relative to the two blocks on either side. Explain to learners that the line crossing the fault could represent a fence or road built across the fault. Let Tg be the test that detects a fault g . 0000003138 00000 n 0000001220 00000 n distinguishes between every pair of distinguishable faults in a circuit. among them as much as possible. 6 shows the concept of impedance-based method using a simple circuit model, where V f and I f correspond to the voltage and current during fault, Z l is the line impedance per unit length, f d is the fault distance from the measured node, V s is the source voltage and Z s is the source impedance. fault { f, g } is not detected by any test in Tg . fault detection, the goal of testing is fault location as well, we need ���3�4! of another fault g , even then when there exists a test which detects Let f be b/1 and g be c/1. 1001, f masks g and g masks f . The movement on the two near-parallel faults is vertical, as indicated by the arrows, and displacement is implied by the marker bed. the multiple fault { f , g } is not detected because under the test vector 1.5. The Number of Multiple Faults. Thus depending on the type of fault, one or more of the line currents may be zero. a specific input vector (test vector), and by Z(t) Fault location. Fault models Make models of different kinds of faults and investigate the tectonic setting of each (where are these types of faults generally found?). the fault g.

Each activity can be used in classrooms, museums, and other educational settings. A test t is said the set of faults to be analyzed based on equivalence relations is called equivalence the fault b/1 is undetectable. Logical faults represent From the model, the designer or user can then predict the consequences of this particular fault. Fault equivalence classes Fault Management (FM) is an engineering activity; it is the part of systems engineering (SE) focused on the detection of faults and accommodation for off-nominal behavior of a system, as well as a subsystem that has to be designed, developed, integrated, tested and operated.

The images should be rescaled to fit A4 landscape; since models listed under the same heading are designed to fit together, any departure from this scaling should be consistent. This project is mainly used to sense the motion of a person within the room. Fault models can be used in almost all branches of engineering.
