Aging properties of a vegetable-based polyurethane foam under high relative humidity and different temperatures
The objective of this study is to assess, characterize, and forecast the aging effects on the mechanical properties of a vegetable-based polyurethane foam (PUF) derived from castor oil under elevated relative humidity conditions and at two distinct load orientations (aligned with the expansion direction and perpendicular to it). Ten specimens were subjected to temperatures of […]

Exploiting Machine Learning Techniques to Predict the Stainless Steel Density Produced by Selective Laser Melting Additive Manufacturing
Porosity is one of the inherent defects that results from the Selective Laser Melting (SLM) additive manufacturing technique. The porosity related to fusion-solidification kinetics, results most often from non-optimally or poorly controlled manufacturing parameters. The density, a porosity indicator, affects the mechanical properties of the manufactured material (fatigue strength, cracks, deformations, etc.). Stainless steels are […]

Integrating Human-Centricity, Sustainability, and Resilience in Digital Twin Models for Industry 5.0: A Multi-Objective Optimization Approach
This paper presents the InduDesc framework, an innovative digital twin model within the CupCarbon software, designed for the advanced needs of Industry 5.0. It integrates human-centred ergonomics, sustainability and resilience into the Flexible Job Shop Scheduling Problem (FJSP), traditionally an NP-hard challenge. By minimising operating times and balancing machine utilisation with ergonomic and sustainability considerations, […]

A polynomial algorithm for periodic scheduling
We are interested in problems related to periodic scheduling, driven by applications using networks in which terminals send identical flows periodically. The management of such flows must not only minimize latency, but also jitter, and we have shown that classical methods of sizing networks by statistical multiplexing are not suitable for this situation.

Improving Semantic Mapping with Prior Object Dimensions Extracted from 3D Models
Semantic mapping is a critical challenge that must be addressed to ensure the safe navigation of mobile robots. Equipping robots with semantic information enhances their interactions with humans, as well as their navigation and task planning capabilities. Semantic maps go beyond occupancy information, providing supplementary details about mapped elements that empower robots to gain a […]
