Hardware Security Failure Scenarios

November 13, 2024
Author(s)
Peter Mell, Irena Bojanova
Historically, hardware has been assumed to be inherently secure. However, chips are both created with software and contain complex encodings (e.g., circuit designs and firmware). This leads to bugs, some of which compromise security. This publication

Knowledge Extraction in Additive Manufacturing: a Formal Concept Analysis Approach

November 13, 2024
Author(s)
Zhuo Yang, Yan Lu, Yande Ndiaye, Mario Lezoche, Herve Panetto
In Additive Manufacturing (AM), it is still a major challenge to manage part quality, which is heavily influenced by feedstock materials, process settings, and in-process control. Deviations in these factors can lead to defects in the final product
