A numerical scheme is presented to design a lattice support for metallic components additively built via laser powder bed fusion. Results show that thermal‐induced distortion can be respectively reduced by 69%, 58%, and 50% in comparison to a uniform lattice, a fully solid support, and a truss‐based lattice support.

Model-Based Generation of Attack-Fault Trees [PDF]
Joint safety and security analysis of cyber-physical systems is a necessary step to correctly capture inter-dependencies between these properties. Attack-Fault Trees represent a combination of dynamic Fault Trees and Attack Trees and can be used to model and model-check a holistic view on both safety and security.

An Automated Fault Tree Generation Approach With Fault Configuration Based on Model Checking
Fault tree generation technology is a key issue for safety analysis of large complex systems. Traditional safety analysis methods usually describe the origin, propagation, or concrete behavior of the fault and do not portray the constraints between ...
