Abstract A Bayesian framework to characterize ground motions even in the presence of missing data is developed. This approach features combination seismological knowledge ( a priori ) with empirical observations (even incomplete) via inference. At its core neural network model that probabilistically learns temporal patterns from motion data. Uncertainties are accounted for throughout framework....

In order to develop a novel voice sensor to detect human voices, the use of features which are more robust to noise is an important issue. Voice sensor is also called voice activity detection (VAD). Due to that the inherent nature of the formant structure only occurred on the speech spectrogram (well-known as voiceprint), Wu et al. were the first to use band-spectral entropy (BSE) to describe t...

The accurate modelling of seismic load is a major topic that has raised particular interest in the literature in the recent years. One of the reasons is the advent of performance based earthquake engineering (PBEE) that has become the state of the art for both civil and nuclear structures. The PBEE generally requires transient analysis in order to evaluate the seismic fragility of structures an...

We examined the determinants of resting energy expenditure (REE) in 127 observations in 56 burned children. Predicted basal energy expenditure (PBEE), body surface area (BSA), and body weight correlated significantly with REE (r2 = 0.76). Days postburn and burn size (% BSA burned) only accounted for 21%, and 24% of the variation in the elevation in REE above PBEE. The single most powerful predi...

This paper is a progress report of a MCEER research project on the development of multihazard protection technologies for critical facilities. One important component is to consider earthquake and earthquake induced hazards (e.g. fire, haz-mat leakage, power outrage, etc). This paper is concerned with earthquake and subsequent fire hazards. Records from historical earthquakes show that sometime...

The SAFE (Satellites For Epidemiology) project is co-funded by the European Space Agency (ESA) and coordinated by MEDES (FRANCE). In a twoday earthquake readiness exercise that was held on the island of Crete, Greece, on November 5-6, 2007, it demonstrated a component-based system for health early warning. The exercise that was coordinated by the Prefecture of Heraklion and FORTH-ICS, involved ...

The catastrophic consequences of recent NaTech events triggered by earthquakes highlighted the inadequacy standard approaches to seismic risk assessment chemical process plants. To date, such facilities mainly relies on historical data and focuses uncoupled components. As a consequence, dynamic interaction between equipment is neglected. In response this gap, researchers started progressive int...

Abstract Developing fragility functions is the essential step in incorporating important uncertainties next-generation performance-based earthquake engineering (PBEE) methodology. The present paper aimed to involve record-to-record variability as well modelling uncertainty sources developing curves at collapse limit state. In this article, order reduce dispersion of uncertainties, Group Method ...

Probabilistic seismic demand analysis (PSDA) is known as one of the critical intermediate steps in performance-based earthquake engineering (PBEE) design framework. Accuracy PSDA influenced by various sources uncertainties and mostly that stemming from ground motion-related variabilities. By taking a representative reinforced concrete (RC) continuous girder bridge case study, twenty-eight commo...
