MFFTNet: A Novel 3D Point Cloud Segmentation Network Based on Multi-Scale Feature Fusion and Transformer Architecture by Hao Bai, Xiongwei Li, Qing Meng, Shulong Zhuo, Lili Yan

“…Intelligent analysis of 3D point clouds has become a frontier in emerging fields such as autonomous driving, digital twins, and the metaverse. Precise segmentation of 3D point clouds is particularly important within these domains; however, it faces several challenges: <xref ref-type="disp-formula" rid="deqn1">(1)</xref> point cloud data inherently lacks structured topological information; <xref ref-type="disp-formula" rid="deqn2">(2)</xref> point cloud shapes are complex and highly variable, making it difficult to utilize semantic priors; and <xref ref-type="disp-formula" rid="deqn3-deqn6">(3)</xref> the sampling process of point clouds may result in sparse and uneven data. …”

Reflections and trajectories for interdisciplinary research on the energy transition by Cesare Sposito, Francesca Scalisi

“…In that case, the vast existing real estate heritage is an area in which it is possible to intervene effectively, even where it has a historical and cultural value, using tools such as digital twins or analysis methodologies capable of assessing ex-ante the impacts on the ecosystem and prefigure scenarios for cities, buildings and production processes aimed at sustainable development and compatible with the urgent objectives set for 2030 and 2050. …”
