RISFast and Scalable Likelihood-Free Bayesian Model Updating for Multiple-Measurement Data via Conditional Invertible Neural Network and Posterior Stacking
Publisher: American Society of Civil Engineers
Abstract: AbstractBayesian model updating (BMU) is widely used in structural health monitoring (SHM)
to calibrate model parameters and quantify uncertainties. However, a key challenge
in BMU is the intractability of the likelihood ...
Spatial Estimation of Material Parameters and Refined Finite-Element Analysis of Rockfill Dam Based on Construction Digitization
Publisher: American Society of Civil Engineers
Abstract: Quality levels for rockfill dam compaction (herein, porosity is an important index for assessing dam-material compaction quality) in any location can be estimated based on construction digitization technologies. According ...
Interdecadal Variability of Summer Rainfall in Taiwan Associated with Tropical Cyclones and Monsoon
Publisher: American Meteorological Society
Abstract: his study investigates interdecadal variability of summer (June?August) rainfall in Taiwan for the 1950?2008 period. Summer rainfall in Taiwan is partitioned into two components: tropical cyclone (TC) rainfall caused by ...
Coherent Interdecadal Variability of Tropical Cyclone Rainfall and Seasonal Rainfall in Taiwan during October
Publisher: American Meteorological Society
Abstract: y separating total rainfall into tropical cyclone (TC) rainfall caused by TC passage and seasonal rainfall associated with moisture transport of prevailing seasonal flows, this study examines the interdecadal variability ...
Numerical Investigation of the Clocking Effect Between Inducer and Impeller on Pressure Pulsations in a Liquid Rocket Engine Oxygen Turbopump
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The clocking positions between the inducer and the impeller have a certain impact on the performance of the high-speed centrifugal pump, which however, is often ignored by designers. In the present study, three-dimensional ...
Study on Tribological Properties of a New Fe3Al-Based Alloy as an Alternative Material for Scraper Conveyor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work reports on the sliding wear properties of Fe3Al-based alloy in conditions of dry sliding and quartz sand abrasion. The wear strengthening mechanism is also analyzed in detail. On this basis, the feasibility of ...
Optimization Analysis of Two-Phase Flow Distributor for Multichannel Heat Exchanger
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. The flow maldistribution in plate heat exchangers (PHEs) is serious, which hinders efficient operation. In this study, a multichannel two-phase flow model in porous media is established, and flow maldistribution ...
Numerical Simulation of the Temperature Field and Deformation of Subgrade for Sunny-Shady Slopes in a Seasonal Frozen Region
Publisher: American Society of Civil Engineers
Abstract: The second and third types of boundary conditions were mixed to simulate the change rule for the subgrade temperature field under the actual climate condition in a seasonal frozen region. The temperature difference between ...
Interannual Variability of Summer Tropical Cyclone Rainfall in the Western North Pacific Depicted by CFSR and Associated Large-Scale Processes and ISO Modulations
Publisher: American Meteorological Society
Abstract: AbstractThis study examines the interannual variability of summer tropical cyclone (TC) rainfall (TCR) in the western North Pacific (WNP) depicted by the Climate Forecast System Reanalysis (CFSR). This interannual variability ...
Ni-ZIF-8@ZIF-67-Derived Bimetallic Doped Pt-Based Carbon Catalyst for Hydrogen Evolution Reaction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The development of highly active and stable electrocatalysts is a major challenge for water electrolysis. In this work, we designed bimetallic nitrogen-doped carbon (NiCo-NC) materials with excellent performance, which ...
