Evalaution and optimization of laser cutting parameters for plywood materials [PDF]
, 2013 Laser process parameters influence greatly the width of kerfs and quality of the cut edges. This article reports experiments on the laser plywood-cutting performance of a CW 1.5 kW CO2¬ Rofin laser, based on design of experiments (DOE).

Parameter estimation in Manneville–Pomeau processes
Probability, Uncertainty and Quantitative Risk, 2023 In this work we study a class of stochastic processes $\{X_t\}_{t\in\N}$, where $X_t = (ϕ\circ T_s^t)(X_0)$ is obtained from the iterations of the transformation T_s, invariant for an ergodic probability μ_s on [0,1] and a continuous by part function $ϕ:[0,1] \to \R$. We consider here $T_s:[0,1]\to [0,1]$ the Manneville-Pomeau transformation.

Relationships between LRI process parameters and impact and post-impact behaviour of stitched and unstitched NCF laminates [PDF]
, 2012 The general context of the development of out-of-autoclave processes in the aeronautics industry raises the question of the possible links between these new processes and impact behaviour. In this study, a Taguchi table was used in a design of experiment
