The mechanical properties and plastic deformation mechanisms of metal nanowires have been studied intensely for many years. One of the important yet unresolved challenges in this field is to bridge the gap in properties and deformation mechanisms reported for slow strain rate experiments (∼10-2 s-1), and high strain rate molecular dynamics (MD) simulations (∼108 s-1) such that a complete unders...

Fault analysis (detection, classification and location) of transmission network is great importance in power system. A Wavelet-Alienation-Neural (WAN) technique has been developed for the fault Unified Power Flow Controller (UPFC) compensated network. The detection various outages are accomplished by alienation wavelet based approximate coefficients computed from current signals. precise locati...

This work employs high-resolution 3D thermomechanical numerical models of the incipient oceanic spreading to investigate nucleation and long-term evolution of ridge-transform spreading patterns. The Eulerian–Lagrangian visco-plastic model allows for large strains and accounts for plate cooling by both heat conduction and hydrothermal circulation as well as for partial melting of the asthenosphe...

Oil-submerged transformer is one of the inherent instruments in South African power system. Transformer malfunction or impairment may interpose operation electric distribution and transmission system, coupled with liability for high overhaul costs. Hence, recognition inchoate faults an oil-submerged indispensable it has turned into intriguing subject interest by utility owners manufacturers. Th...

Stator winding faults are one of the most common permanent magnet synchronous motors (PMSMs), and searching for methods to efficiently detect this type fault at an early stage damage is still ongoing, important topic. This paper deals with selected detecting stator (short-circuits) a motor, which based on analysis phase current signal. These were experimentally verified their effectiveness was ...

Abstract Carbonate U-Pb dating of samples from rift-bounding faults intracontinental basins in the Borborema province, northeastern Brazil, indicate recurrent tectonic activity during Pangea breakup lasting for >150 m.y. Late Triassic to Paleocene, reactivating inherited strike-slip Neoproterozoic–Cambrian shear zones. ages that brittle deformation started some 80 before previously known...

Incipient fault detection plays a crucial role in preventing the occurrence of serious faults or failures industrial processes. In most processes, linear, and nonlinear relationships coexist. To improve performance, both linear features should be considered simultaneously. this article, novel hybrid linear-nonlinear statistical modeling approach for data-driven incipient is proposed by closely ...

Abstract We present the Malawi Active Fault Database (MAFD), an open‐access ( https://doi.org/10.5281/zenodo.5507190 ) geospatial database of 113 fault traces in and neighboring Tanzania Mozambique. is located within East African Rift's (EAR) Western Branch where active identification challenging because chronostratigraphic data are rare, and/or faults buried so do not have a surface expression...

Numerous condition monitoring techniques and identification algorithms for detection and diagnosis of faults in industrial plants have been proposed for the past few years. Motors are one of the common used elements in almost all plant machinery. They cause the machine failure upon getting faulty. Therefore advance and effective condition monitoring techniques are required to monitor and detect...

In condition monitoring of ball bearings, traditional techniques involving vibration, acceleration may not be able to detect a growing fault due to the low impact energy generated by the relative motion of the components. This study presents an experimental evaluation for incipient fault detection of lightly loaded ball bearings by using acoustic emission method. A table top bearing test rig is...
