Evaluation of critical factors for typhoon-triggered landslide and subsequent debris flow in the Philippines using physically based models by Christian Gaviola John, Chieh Chao Kuo, Bencure Jannet

“…The TRIGRS and DEBRIS-2D models simulated transient infiltration effects from four days of continuous rainfall, assessing pore water pressure changes and delineating hazard zones. Parametric analyses on critical parameters—such as fstrength characteristics, soil thickness, and water table conditions—were conducted to predict spatiotemporal changes in the factor of safety. …”

Influence of Coal Cleats on Conical Pick Cutting Process Based on PFC by Jinxia Liu, Chao Zhang, Fanchang Zeng, Wenting Liu

“…The simulation results show that lump coal chips begin to form and fall off after the conical pick cuts to 50°; the cleats near the conical pick grow to be more obvious fractures; the mean and maximum fluctuations of cutting force increase with the increase of face and butt cleat spacing; the lower the density of cleat is, the more the cracks are formed during the cutting process; the face cleat spacing has greater influence on the service life of conical pick than the butt cleat spacing. …”

Research on constrained policy reinforcement learning based multi-objective optimization of computing power network by Linjiang SHEN, Chang CAO, Chao CUI, Yan ZHANG

“…The computing power network needs to maximize the system performance index on the basis of meeting user business needs, and the existing methods are mainly based on the multi-objective weighting method, which has problems such as difficult to determine hyperparameters and poor cross-scenario applicability.Based on this, based on the analysis of the characteristics of the computing power network target, the user business requirements were taken as the policy constraints, and the performance indicators of the computing power network was taken as the optimization goal based on constrained policy optimization, and the expectation certainty of user business needs and the optimization of system performance through the value-strategy-hyper-parameter multi-level iterative strategy was realized.At the same time, the multi-scale step length (MSL) method for hyper-parameter optimization was studied, which further improved the stability and accuracy of the system.Simulation results show that the proposed method has good convergence and stability under the conditions of single terminal-single edge server, multi-terminal-multi-edge server and system load change.…”

Optimal Stochastic Control Problem for General Linear Dynamical Systems in Neuroscience by Yan Chen, Yingchun Deng, Shengjie Yue, Chao Deng

“…Moreover, the optimal trajectory is almost a straight line for a reaching movement; the optimal velocity bell-shaped and the optimal variance are consistent with the experimental Fitts law; that is, the longer the time of a reaching movement, the higher the accuracy of arriving at the target position, and the results can be directly applied to designing a reaching movement performed by a robotic arm in a more general environment.…”

Communication framework for directed transmission of informative semantic by Guangming SHI, Minxi YANG, Dahua GAO, Jingxuan CHAI

“…As the traditional communication development model focusing on enhancing bandwidth and spectrum efficiency is getting bottlenecked, more and more research is shifting the goal of intelligent communication from the syntactic level to the semantic level to save bandwidth resources by sensing and transmitting semantics rather than the complete signal.For the receiver agent, it is enough to receive only the information part of the understandable semantics.If the informative parts from the semantics can be filtered for transmission, it will further reduce the bandwidth resources and the time and power consumption of semantic information processing at the sender-side.To this end, firstly, the process of semantic information processing and comprehension of an intelligent body was explored.Secondly, the semantics perceived by the receiver from the message were classified into redundant semantics, unintelligible semantics, and informative semantic.Then, a communication paradigm oriented to transmitting the informative part of the semantics, called informative communication, was proposed, and the communication paradigm was extended to include four layers: syntax, semantic, informative, and pragmatic.Finally, the feasibility and effectiveness of informative communication were verified through simulation.This provides new ideas and technical traction for the development of next-generation communication models.…”
