Model uncertainty is prevalent in probabilistic seismic hazard analysis (PSHA) because the underlying statistical signatures for hazard are unknown. Although methods for incorporating parameter uncertainty of a particular model in PSHA are well understood, methods for incorporating model uncertainty are more difficult to implement because of the high degree of dependence between different earth...

Probabilistic seismic hazard maps are widely used for engineering design, land use planning, and disaster mitigation etc. This study conducted a review of readily available information on tectonic setting, geology, and seismicity, and the attenuation of peak ground acceleration (PGA) of Taiwan for completing the revised probabilistic seismic hazard maps by the state-of-the-art probabilistic sei...

PURPOSE Implant surface treatments that improve early osseointegration may prove useful in long-term survival of uncemented implants. We investigated Acid Etching and Plasma Cleaning on titanium implants. METHODS In a randomized, paired animal study, four porous coated Ti implants were inserted into the femurs of each of ten dogs. PC (Porous Coating; control)PC+PSHA (Plasma Sprayed Hydroxyapa...

Probabilistic seismic hazard analysis (PSHA) combines the probabilities of all earthquake scenarios with different magnitudes and distances with predictions of resulting ground motion intensity, in order to compute seismic hazard at a site. PSHA also incorporates uncertainties in ground motion predictions, by considering multiple Ground Motion Prediction ("attenuation") Models (GMPMs). Current ...

Three different implants, bare Ti-6Al-4V alloy, Ti-6Al-4V alloy coated with plasma-sprayed hydroxyapatite (PSHA), and Ti-6Al-4V alloy coated with electrochemically deposited hydroxyapatite (EDHA), were implanted into canine trabecular bone for 6 h, 7, and 14 days, respectively. Environmental scanning electron microscopy study showed that PSHA coatings had higher bone apposition ratios than thos...

Probabilistic seismic hazard analysis (PSHA) is the standard method used for designing earthquake-resistant infrastructure. In recent years, several unexpected and destructive earthquakes have sparked criticism of PSHA methodology. The seismological part problem true frequency-magnitude distribution regional seismicity. Two major models exist, Gutenberg-Richter (G-R) Characteristic Earthquake (...

Probabilistic Seismic Hazard Assessment (PSHA) evaluates the probability of exceedance a given earthquake intensity threshold like Peak Ground Acceleration, at target site for exposure time. The stochasticity occurrence seismic events is modelled by stochastic processes and propagation wave in soil typically evaluated empirical relationships called Motion Prediction Equations. large uncertainty...

Probabilistic seismic hazard analysis (PSHA) has been recognized as a reasonable method for quantifying threats. Traditionally, this ignores the effect of focal depth, in which ground motion prediction equations (GMPEs) are applied to estimate probability distribution associated with possible levels induced by site earthquakes, but it is limited unclear geological conditions, makes difficult pr...
