... (RNN), Genetic Algorithm (GA), and Particle Swarm Optimization (PSO) were tested under the framework of representation learning and optimization. In the preset computing environment, the normalized RMSEs of representation learning are 0.21 and 0.17, and the calculation takes less than 0.1 second...

... representation of the tunnel structure in the form of a digital twin, facilitates the answer to the initial question (Flora et al. 2020). Furthermore, the progressing application of BIM in tunnel and infrastructure design (Tunnel Information Modelling - TIM), shows that there are still limits to implementing...

... ABSTRACT: Rock mass characterization involves field data collection, processing, and analysis of the measurement results. Software packages facilitate creation of 3D models as well as the representation of rock mass parameters and resulting block arrays. The computer-generated imagery...
