Finite strain and vorticity analyses were carried out in the deformed conglomerate and micro-conglomerate of Goushti shear zone in the Sanandaj-Sirjan metamorphic belt (Zagros Mountains Iran). These deformed rocks are bounded between two NE and SW major thrust faults. Finite strain measurements on three principal planes of strain ellipsoid show the higher amounts of strain ratios near the major...

Understanding the folding style of a fold-thrust belt is crucial to understand the nature and structural history of structures that may trap natural resources within the belt. In this research, the geometry and mechanism of a number of fault-related folds has been investigated based on field data and satellite image interpretations. The main study areas are: the Sohrevard and Ushtaniyan anticli...

Actuator and sensor faults can cause poor performance or even instability in dynamic systems. In flight control systems for aircraft and spacecraft, such faults can lead to loss of control and serious incidents. Therefore, rapid detection and identification of actuator and sensor faults is important for enhancing flight safety. One approach to fault detection and identification (FDI) in actuato...

We study the class of “bounded faults” in random-access memories; these are faults that involve a bounded number of cells. This is a very general class of memory faults that includes, for example, the usual stuck-at, coupling, and pattern-sensitive faults, but also many other types of faults. Some bounded faults are known to require deterministic tests of length proportional to n log2 n, where ...

March tests have been widely used for detecting functional faults during SRAM testing. Recent development has extended the March test for diagnostic purpose to locate and identify the fault types. This paper analyses March algorithms for detection and diagnosis of Stuck-At Faults (SAFs) and Transition Faults (TFs). Unfortunately, the algorithms under studied are not able to distinguish between ...

We describe a time-e cient procedure for removing sequentially redundant faults from synchronous sequential circuits with synchronizing sequences. We use properties of redundant faults and propose several methods to identify subsets of redundant faults that can be removed simultaneously from the circuit. By removing several redundant faults simultaneously, the number of repetitions of the test ...

In this paper, the noise of electric motors is analyzed in order to obtain information for the detection of faults. Significant noise spectrum differences between healthy motor and motors with different faults are observed. The faults analyzed are bad bearing in the three phase induction motor and broken bars in single phase induction motor. The high-frequency spectral analysis of noise provide...

The new memory technologies and processes are introducing defects that cause faults that were unknown previously. One of the new observed faults in real designs are called dynamic faults. The paper gives a mathematical analysis of such a fault class based on the fault primitive concept. The dynamic fault space will be then established; within this space dynamic functional fault models can be st...

We perform dynamic simulations of thrust and normal faults over multiple earthquake cycles. Our goal is to explore effects of asymmetric fault geometry on the long-term seismicity and dynamics of dipping faults. A dynamic finite-element method is used to model the interseismic and coseismic processes, with a dynamic relaxation technique for the former. The faults are loaded by stable sliding al...
