A central limit theorem for functions of stationary max-stable random fields on R-d

Max-stable random fields are very appropriate for the statistical modelling of spatial extremes. Hence, integrals of functions of max-stable random fields over a given region can play a key role in the assessment of the risk of natural disasters, meaning t ...

Nonmodel-based framework for rapid seismic risk and loss assessment of instrumented steel buildings

Dimitrios Lignos, Seong-Hoon Hwang

This paper proposes a nonmodel-based framework for estimating story-based engineering demand parameters (EDPs) in instrumented steel frame buildings with steel moment-resisting frames (MRFs). The proposed framework utilizes a wavelet-based damage-sensitive ...

Earthquakes do not kill people, buildings do. Transforming existing cities in earthquake resilient systems should be the main goal for researchers in the field of the seismic analysis of entire towns. Providing means for realistic disaster risk scenario ca ...

Crise et gouvernance

Abigaïl-Laure Sarah Irène Kern

On January 12 2010, Haiti was hit by an earthquake of 7.2 on the Richter scale. Close to 220,000 persons died, more than 300,000 were wounded and almost two other million were displaced. The earthquake¿s epicenter was actually several kilometers away the c ...

Unsupervised Change Detection in Satellite Images using Oversegmentation and Mutual Information

Bahar Taskesen, Beril Besbinar

In this paper, a novel solution to the problem of unsupervised change detection in bitemporal satellite images is presented. Information measures, which are well-known and commonly-used in the change detection literature, result in unsharp change maps and ...

From innovation in the construction sector in Haiti to social impact on Haitian society: Digital Norms by Assimilation DNA

Abigaïl-Laure Sarah Irène Kern

The impact of the earthquake of 2010 was aggravated by the precarious housindg of the vulnerable Haitian population. Although disaster risk reduction and building sector regulations are today national priorities, Haiti lacks adequate training entities. The ...

UAVs using Bayesian Optimization to LocateWiFi Devices

Bixio Rimoldi, Stefano Rosati, Mohammad Emtiyaz Khan, Mattia Carpin

We address the problem of localizing non-collaborative WiFi devices in a large region. Our main motive is to localize humans by localizing their WiFi devices, e.g. during search-and-rescue operations after a natural disaster. We use an active sensing appro ...

Automated Damage Index Estimation of Reinforced Concrete Columns for Post-Earthquake Evaluations

The safety of buildings which have been affected by a natural disaster such as an earthquake is currently evaluated manually by certified inspectors who identify visible damage on the structural elements. This process has been proven to be time-consuming, ...
