In most industries, the working conditions of equipment vary significantly from one site to another, time a year and so on. This variation poses severe challenge for data-driven fault identification methods: it introduces change in data distribution. contradicts underlying assumption machine learning methods, namely that training test samples follow same Domain Adaptation (DA) methods aim addre...

The 2016 Central Italy earthquake sequence is characterized by remarkable rupture complexity, including highly heterogeneous slip across multiple faults in an extensional tectonic regime. dense coverage and high quality of geodetic seismic data allow us to image intriguing details the kinematics largest sequence, Mw 6.5 October 30th, Norcia earthquake, such as energetically weak nucleation phas...

Normal faults border many a continental shelf, but have only been considered to play subordinate role basin-controlling in previous studies. Their detailed geometries and kinematic histories are still poorly known. In this study, high-quality three dimensional (3D) seismic data used investigate distinct families of normal bordering the shelf Qiongdongnan Basin, northwest South China Sea. Sixty-...

SUMMARY We constructed an integrated rupture model of the 2021 Mw 7.1 Fukushima earthquake, intraplate by resolving both its spatiotemporal distribution slip-rate and high-frequency (∼1 Hz) radiations. analysed near-field seismic observations using a novel finite-fault inversion method that allows automatic parametrization teleseismic data from multiple arrays MUSIC backprojection (BP) enhances...

Concern about fault tolerance in the design of interconnection networks has aroused interest in finding large graphs such that the subgraphs obtained by deleting any set of up to s vertices have small diameter. Clearly, 1 ≤ s ≤ ∆ − 1, where ∆ is the maximum degree of the graph. Graphs of maximum degree ∆, diameter ≤ D and such that the graphs obtained by deletion of up to s vertices have diamet...

Computer-aided fault imaging and interpretation is a fundamental tool for subsurface structure characterization and modeling, and the existing methods are primarily based on seismic discontinuity analysis (e.g., coherence and semblance) that evaluates the lateral variation of waveform and/or amplitude. However, such attributes have a limited resolution on subtle faults without apparent displace...

We introduce the new Masked Interval Routing Scheme, MIRS for short, where a mask is added to each interval to indicate particular subsets of "consecutive" labels. Interval routing becomes more exible, with the classical IRS scheme being a special case of MIRS. We then take two directions. First we show that the interval information stored in the network may be drastically reduced in the hard c...

How to efficiently mimic the wing shape and kinematics pattern of an able hovering living flier is always a concern of researchers from the flapping wing micro aerial vehicles community. In this work, the separate or combined optimizations of wing geometry or/and wing kinematic parameters are systematically performed to minimize the energy of hovering flight, firstly on the basis of analyticall...

Recent observations suggesting the influence of creep on earthquakes nucleation and arrest are strong incentives to investigate the physical mechanisms controlling how active faults slip. We focus here on deriving generic characteristics of shallow creep along the Haiyuan fault, a major strike-slip fault in China, by investigating the relationship between fault slip and geometry. We use optical...

We determined the centroid moment tensor (CMT) solutions of earthquakes that occurred along the North Anatolian fault (NAF) beneath the Sea of Marmara and the Aegean Sea, using data obtained from Turkey’s broadband seismograph network. The CMT solution of the 2014 Aegean Sea earthquake (Mw 6.9) represents a strike-slip fault, consistent with the geometry of the NAF, and the source-time function...
