Dislocation mechanisms and 3D twin architectures generate

3d twinAbstract. In this article, we propose a 3D mobile crowdsensing (3D-MCS) framework aimed at sustainable urban dital twins (UDTs). The framework comprises four key mechanisms:Dital Twin tech revolutionizes CNC manufacturing, enhancing precision, minimizing errors, optimizing workflows, and speeding up production from desn to final product.
