    Stabilization and Synchronization of a New 3D Complex Chaotic System via Adaptive and Active Control Methods by Lamia Loudahi, Jing Yuan, Lydia Dehbi, Mawia Osman

    Published 2025-05-01
    “…This paper investigates the controllability and synchronization of a newly designed three-dimensional chaotic system using active and adaptive control strategies. Although both controllers were designed with the help of a positive definite function using Lyapunov theory, for adaptive controllers, we estimated an unknown parameter of the system in real time and adjusted the control signal accordingly to maintain stability. …”

    Exposure assessment to fine and ultrafine particulate matter during welding activity in the maintenance shop of a steelmaking factory by Sergio Pili, Luigi Isaia Lecca, Tatiana Pedrazzi, Roberta Ghitti, Alessandro Murru, Michele Uras, Daniele Fabbri, Marcello Campagna, Giuseppe De Palma

    Published 2024-12-01
    “…Our study aims to evaluate the exposure to fine and ultrafine airborne particulate in welding operators working in a steel making factory.In October 2019, air monitoring was performed for four days in five different welding scenarios and in the external area of a steelmaking factory to assess the exposure to airborne particles, ultrafine (UFP) particulate and inhalable fraction, during welding activities. The airborne particles distribution as particle number and mass concentration were measured using a low-pressure electric impactor, model ELPI™ (range of sampling 0.006 μm and 10 μm), whereas the airborne inhalable fraction was collected by filtration, using the IOM Sampler selector.The particle concentration, i.e. the number of particles per cm3 (part/cm3) showed significantly higher exposure figures for nanoscale particles, especially for the fractions included in the last 4 stages sampled by ELPI (from 0.010 μm to 0.071 μm), the figure representing between 85 % and 91 % of the total, whereas for the last 7 stages (0.010 μm–0.314 μm), they represented from 98 % to 99 % of the total. …”
