Abstract We study the spatial variation in earthquake ground motions, or equivalently dynamic displacement gradient field, using a novel analysis procedure borrowed from geodesy. Seismic data recorded Valley of Mexico by microarray three three-component surface accelerographs and two at depths 30 m 102 constrain our estimates field (from which strains rotations derive) for four moderate earthquakes distances 250 to 300 km. Our focuses on effects low-velocity materials deformation. At...
Summary Local small-scale heterogeneities, like geological inhomogeneities, surface topographies and cavities are known to affect seismic wavefield gradients. This effect is in fact measurable with current instruments. For example, the agreement between data synthetics computed a tomographic model often not as good for rotation it displacement. Here, we use theory of homogenization explain why heterogeneities strongly gradients, but itself. We show that at any receiver measuring gradient,...
Abstract We develop simple relations to estimate dynamic displacement gradients (and hence the strains and rotations) during earthquakes in lake-bed zone of Valley Mexico, where presence low-velocity, high-water content clays uppermost layers cause dramatic amplification seismic waves large strains. The study uses results from a companion article (Bodin et al., 1997) which data an array at Roma, site, were analyzed obtain gradients. In this article, we find that deformations other sites may...
SUMMARY Seismic gradient measurements from distributed acoustic sensors and rotational are becoming increasingly available for field surveys. These provide a wealth of information currently being considered many applications such as earthquake detection subsurface characterizations. In this work, using simple 2-D numerical approach, we tackle the implications wavefield on full waveform inversion (FWI) techniques test. particular, study impact measurement sensitivity to heterogeneities that...
Managing Hot Carrier Injection degradation in digital applications becomes a great challenge for advanced technology nodes. A methodology of introducing design flow is demonstrated. Model based on renormalization damage function including an energy driven and carrier density modes. Additionally, the first time, HCI degradation-induced dispersion presented calibrated. Finally, applicability our model proven at circuit-level. Simulated results are line with experimental drifts observed after...
Sustainability evaluation of two iconic bridge corridors under construction using Fuzzy Vikor technique: A case studyABSTRACTTwo projects over river Yamuna in Delhi have been evaluated from sustainability criteria Fuzzy-Vikor technique. The Barapulla elevated road project was more found to be sustainable comparison the Signature terms various indicators identified during study. In general, goals providing features are finding a balance between what is important community, natural environment...
Liquefaction of saturated soil has often been one the causes earthquake damage to structures resulting in loss life and property. The additional safety design superstructure is not any help event liquefaction foundation during an earthquake. It therefore very necessary that possibility examined before hand remedial measures are adopted against damages due soil. Complex behaviour phenomena makes prediction costly time consuming task. Fortunately, occurs only under certain conditions. To take...
