Seismicity of the northwestern edge of the Gulf of Suez. Full size image The major fault directions in the Gabal Ataqa area are NW–SE-oriented faults. So, three 2D seismic lines are acquired in the SE–NW direction to be in the fault dip direction to delineate the subsurface features, ...
of the three main types of encyclopaedia has had to offer by reading entries on the same subject in theEncyclopédie française,Webster’s Third New International Dictionary(1961), and the 15th edition of theEncyclopædia Britannica. TheEncyclopédie françaisewill provide one or more well-...
faults well known to geologists. From field experience these had been classified into three main types called strike faults, dip faults and oblique faults which conformed to neither of these directions. With increasing knowledge it was found that the majority of those in the first class were over...
The capability of the proposed method is evaluated by simulating different types of faults including inrush currents, internal faults, and simultaneous occurrence of inrush and fault currents. The obtained data from the PSCAD-EMTDC output file is used as an input to the algorithm. The output of...
Rock masses contain ubiquitous multiscale heterogeneities, which (or whose boundaries) serve as the surfaces of discontinuity for some characteristics of the stress state, e.g., for the orientation of principal stress axes. Revealing the regularities that control these discontinuities is a key to und...
The three procedures of public announcement of administrative law enforcement, record of the whole process of law enforcement and legal review of major law enforcement decisions are to be strictly followed, and it is necessary to fully implement the system of notification and commitment of fire ...
Active disturbance rejection control (ADRC) is a model-independent method widely used in passive fault-tolerant control of the quadrotor unmanned aerial vehicle. While ADRC’s effectiveness in actuator fault treatment has been proven, its tolerance to sensor faults requires improvements. In this paper...
and then the wavelet packet algorithm was used to extract the frequency band energy and the 2-norm as the time-frequency domain indexes, the PCA (Principal Component Analysis) was used to confirm the principal component, and the crack fault of the wind turbine gearbox was diagnosed effectively....
