RISQuantitative Analysis and Spatial Pattern Research of Built-Up Environments and Surface Urban Heat Island Effect in Beijing’s Main Urban Area
Publisher: ASCE
Abstract: The surface urban heat island (SUHI) phenomenon, predominantly influenced by factors associated with the built-up environment, is prominent in large metropolitan areas. To effectively mitigate the escalating thermal ...
Reliability Analysis of Circular Tunnel Face Stability Obeying Hoek–Brown Failure Criterion Considering Different Distribution Types and Correlation Structures
Publisher: American Society of Civil Engineers
Abstract: A reliability analysis is presented of a circular tunnel face driven by a pressurized shield in a highly fractured Hoek–Brown (HB) rock mass. A limit analysis approach is employed to define a limit state function (LSF) ...

Design of Multiple Operating Degrees of Freedom Planetary Gear Trains With Variable Structure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To obtain multiple speed ratios, a synthesis methodology of planetary gear trains (PGTs) with multiple operating degreesoffreedom (DOFs) is proposed based on the variable structure method. Variable structure of PGT is ...
Spatiotemporal Aggregation Mechanism and Potential Evaluation of Population in the Central Area of Tianjin, China
Publisher: ASCE
Abstract: Low-density urban sprawl is reducing the quality of urbanization, especially in China. Improving the population aggregation degree is an essential means to solve the problem, and in this process, the central urban area ...
