Summary: This research axis aims at developing new probabilistic methods for interpreting in real-time the data recorded on structures. The goal of data interpretation is to detect anomalies in the behaviour of structures in order to trigger preventive actions such as visual inspections and maintenance.

Material Behavior modeling

Lucie Tabor (D)
M.Sc. | 2015 - 2017

Summary: This research axis aims at creating probabilistic models from empirical data. The goal is to capture the behaviour and intrinsic variability observed in the laboratory for advanced materials.

Keywords: Gaussian Process Regression; Heteroscedasticity; Bayesian Methods; Fiber Reinforced Concrete (UHPFRC)

Soil Contamination Caracterization

Alyssa Quach (D) | 2015 - 2016

Summary: This research axis aims at developing an artificial intelligence capable of assisting engineers during the characterization of contaminated sites. The goal is to enable the selection of an optimal soil sampling sequence and locations in order to minimize site characterization costs.

Keywords: Artificial Intelligence; Pre-Posterior Analyses; Gaussian Process Regression; Optimization; Soil Contamination
