MATLAB script for efficiently computing values of permutation entropy from 1D time series in sliding windows
STONEHENGE is an ensemble of open source Matlab and C++ codes for nonlinear dynamic analysis of vibration energy harvesting systems.
IIDAP is a standalone MATLAB-based software capable of performing a variety of dynamic analysis procedures ranging from simple response history analysis to response spectrum and incremental dynamic analyses on single degree-of-freedom systems (SDoF). IIDAP includes a wide-ranging library of SDoF system models ranging from simple non-deterioratin…
SAP2000 by CSI models and analyzes structures including bridges and buildings with linear and nonlinear finite element tools.

Comparative seismic performance assessment of 5 reinforced concrete buildings using SAP2000, including linear, modal, response spectrum, and nonlinear pushover analyses.
This repository presents a minimal early‑warning method for failure detection. Before structural failure, the number of critical points in the signal increases. By extracting raw, smoothed, and critical‑point sequences, and tracking the critical‑point time series, structural changes can be quantified as an early signal.
Lumiere Research Program '25: Comparative analysis of EEG signals using MFDFA and classic FFT to identify neuro-markers for cognitive flexibility. Investigated if multifractal dynamics predict strategy and rule-guessing performance better than traditional spectral analysis. Includes signal preprocessing, feature selection, and model parsimony.
