The ORNL-PSerc-Alaska (OPA) model is a blackout proposed by researchers at Oak Ridge National Laboratory (ORNL), Power System Engineering Research Center of Wisconsin University (PSerc), and Alaska (Alaska). Although the OPA landmark study, it has two limitations. First, there significant difference between simulation practice in transmission line outage update; second, cascading failure probability distribution size are general not accurate enough. Hence, an improved this paper to address...
SUMMARY Earthquake‐induced slope displacement is an important parameter for safety evaluation and earthquake design of systems. Traditional probabilistic seismic hazard analysis usually focuses on evaluating at a particular location, it not suitable spatially distributed slopes over large region. This study proposes computationally efficient framework fully systems using correlated vector intensity measures (IMs). First, spatial cross‐correlation model three key ground motion IMs, that is,...
Estimation of Newmark sliding displacement plays an important role for evaluating seismic stability slopes. Current empirical models generally utilize predefined functional forms and relatively large model uncertainty is involved. On the other hand, machine learning method typically has superior capacity in processing comprehensive data sets a nonparametric way. In this study, framework proposed to predict displacements using extreme gradient boosting (XGBoost) Next Generation Attenuation...
Real-time crowdsourced maps such as Waze provide timely updates on traffic, congestion, accidents and points of interest. In this paper, we demonstrate how lack strong location authentication allows creation software-based Sybil devices that expose map systems to a variety security privacy attacks. Our experiments show single device with limited resources can cause havoc Waze, reporting false congestion automatically rerouting user traffic. More importantly, describe techniques generate at...
Abstract Spatial correlations of ground‐motion intensity measures (IMs) are essential for seismic analysis spatially distributed systems. In this paper, geostatistical is conducted to calculate the spatial cumulative absolute velocity (CAV), Arias (Ia), and spectral accelerations (SA) using a total number more than 1500 earthquake records from nine recent earthquakes occurred in Taiwan, California, Japan. The results indicate that these IMs closely related regional site conditions, they can...
A modified bounding surface hypoplasticity model is developed to capture distinct dilatancy behaviors of loose and dense sandy soils during various phases undrained cyclic loading. Based on observations from laboratory tests, new modulus formulations are proposed improve the simulation mobility postliquefaction both sands. The state-dependent effects accumulated plastic strains moduli also incorporated in this model. demonstrates excellent capabilities through systematic comparison between...
Summary Seismic damage simulation of buildings on a regional scale is important for loss estimation and disaster mitigation cities. However, the interaction among densely distributed in city site, ie, “site‐city (SCI) effects,” often neglected most simulations. Yet, many studies have found that SCI effects are very simulations containing large number tall underground structures. Therefore, this work proposed numerical coupling scheme nonlinear time history analysis considering effects. In...
