Abstract The southwest Iberia margin is widely believed to have hosted the 1755 Great Lisbon earthquake and ensuing tsunami, one of most destructive natural events in European history. Here we combine geophysical data numerical tsunami modelling investigate source mechanism responsible for this event. We find that an intra-plate, lithospheric¬-scale thrust fault located at Horseshoe Abyssal Pla...

The different peculiarities of distribution systems added to the variability generation and integration by sources distributed generation, bring with them challenges for adaptation entire network and, mainly, its protection systems. In this context, work analyzes impacts caused system a after photovoltaic solar source against test scenarios insertion occurrence faults. results demonstrate influ...

Software security defects have a serious impact on the software quality and reliability. It is a major hidden danger for the operation of a system that a software system has some security flaws. When the scale of the software increases, its vulnerability has becoming much more difficult to find out. Once these vulnerabilities are exploited, it may lead to great loss. In this situation, the conc...

Gate camouflaging is a known security enhancement technique that tries to thwart reverse engineering by hiding the functions of gates or the connections between them. A number of works on SAT-based attacks have shown that it is often possible to reverse engineer a circuit function by combining a camouflaged circuit model and the ability to have oracle access to the obfuscated combinational circ...

[1] A mismatch of elastic properties across a fault induces normal stress changes during spatially nonuniform in-plane slip. Recently, Rudnicki and Rice showed that similar effects follow from a mismatch of poroelastic properties (e.g., permeability) within fluid-saturated fringes of damaged material along the fault walls; in this case, it is pore pressure on the slip plane and hence effective ...

Pole-to-pole DC faults on HB-MMC-VSC-HVDC schemes impose significant risk of cascade failure IGBT/diode pairs. Other novel topologies with fault blocking capability, i.e. AAC converters, and circuit breakers are not yet fully matured. Therefore, silicon thyristors used to bypass the until AC activate. However, also at due capacitor voltage collapse high junction temperatures caused imbalanced r...

The study is focused on the effect of transient external force induced by a passing seismic wave on fault motion in different creep regimes. Displacement along the fault is represented by the movement of a spring-block model, whereby the uniform and oscillatory motion correspond to the fault dynamics in post-seismic and inter-seismic creep regime, respectively. The effect of the external force ...

Warning of imminent ground shaking due to a large earthquake would be useful to a variety of agencies. This kind of ground-motion prediction is possible in southern California for events with magnitude less than 6, where path effects dominate. The 28 June 1991 Sierra Madre earthquake is presented as a test case for this concept. A single-station inversion of the record from the Pasadena station...
