Acoustic and relaxation processes in supercooled o-ter-phenyl by optical-heterodyne transient grating experiment
The dynamics of the fragile glass-forming o-ter-phenyl is investigated by
time-resolved transient grating experiment with an heterodyne detection
technique in a wide temperature range. We investigated the dynamics processes
of this glass-former over more then 6 decades in time with an excellent
signal/noise. Acoustic, structural and thermal relaxations have been clearly
identify and measured in a time-frequency window not covered by previous
spectroscopic investigations. A detailed comparison with the density response
function, calculated on the basis of generalized hydrodynamics model, has been
worked out

Using the damage from 2010 Haiti earthquake for calibrating vulnerability models of typical structures in Port-au-Prince (Haiti)
After the 2010 Haiti earthquake, that hits the city of Port-au-Prince, capital city of Haiti, a multidisciplinary working group of specialists (seismologist, geologists, engineers and architects) from different Spanish Universities and also from Haiti, joined effort under the SISMO-HAITI project (financed by the Universidad Politecnica de Madrid), with an objective: Evaluation of seismic hazard and risk in Haiti and its application to the seismic design, urban planning, emergency and resource management. In this paper, as a first step for a structural damage estimation of future earthquakes in the country, a calibration of damage functions has been carried out by means of a two-stage procedure. After compiling a database with observed damage in the city after the earthquake, the exposure model (building stock) has been classified and through an iteratively two-step calibration process, a specific set of damage functions for the country has been proposed. Additionally, Next Generation Attenuation Models (NGA) and Vs30 models have been analysed to choose the most appropriate for the seismic risk estimation in the city. Finally in a next paper, these functions will be used to estimate a seismic risk scenario for a future earthquake.This work has been developed thanks to the financial support of the Universidad Politecnica de Madrid (UPM), project SISMO-HAITI
