    Effects of Thermal Radiation and Variable Porosity on Unsteady Magnetoconvective Heat-Mass Transport Past a Vertical Perforated Sheet by Md. Abu Bkar PK, Md. Hasanuzzaman, Md. Mosharof Hossain, Dipayan Mondal

    Published 2024-01-01
    “…This study interprets the effects of radiative and variable porosity on a time-dependent MHD-free convective heat-mass transfer past a vertical porous sheet. The PDEs governing the research are converted into nondimensional ODEs by inserting the similarity transformation containing a set of physical parameters. …”

    Sequence Analysis of How Disability Influenced Life Trajectories in a Past Population from the Nineteenth-Century Sundsvall Region, Sweden by Lotta Vikström, Helena Haage, Erling Häggström Lundevaller

    Published 2017-05-01
    “…To our knowledge this is the first study to employ sequence analysis on a substantially large number of cases to provide demographic evidence of how disability shaped human trajectories in the past during an extended period of life. Accordingly, we detail our motivation for this method, describe our analytical approach, and discuss the advantages and disadvantages associated with sequence analysis for our case study.…”

    Research on the Temporal and Spatial Evolution Characteristics of Evapotranspiration and Its Components of Guangdong Province Based on GLEAM Dataset in the Past 30 Years by WANG Dayang

    Published 2021-01-01
    “…Based on the remote sensing evapotranspiration dataset of GLEAM,this paper analyzes the temporal and spatial evolution characteristics of evapotranspiration and its components from 1989 to 2018 in Guangdong province,studies the temporal and spatial changes of evapotranspiration in the past 30 years by combining the Mann-Kendall and Sen's slope,and discusses the temporal and spatial evolution trends and patterns of components such as vegetation transpiration,soil evaporation and interception loss,and analyzes the cause of the change in evapotranspiration based on the normalized difference vegetation index (NDVI) of Guangdong province.The research can provide a scientific reference for thorough understanding of surface hydrological processes and energy balance processes under the condition of climate change.…”

    A Navier–Stokes-Informed Neural Network for Simulating the Flow Behavior of Flowable Cement Paste in 3D Concrete Printing by Tianjie Zhang, Donglei Wang, Yang Lu

    Published 2025-01-01
    “…In this work, we propose a Navier–Stokes-Informed Neural Network (NSINN) as a surrogate approach to predict the localized flow behavior of cementitious materials for advancing 3D additive construction technology to gain fundamental insights into multiscale mechanisms of cement paste rheology. NS equations are embedded into the NSINN to interpret the flow pattern in the 3D printing barrel. …”

    Experimental Investigation on Mechanical Properties of Cemented Paste Backfill under Different Gradations of Aggregate Particles and Types and Contents of Cementing Materials by Jiangyu Wu, Meimei Feng, Guansheng Han, Xiaoyan Ni, Zhanqing Chen

    Published 2019-01-01
    “…Obtaining the optimal gradation of aggregate particles is beneficial for improving the strength of cemented paste backfill (CPB). Consequently, the uniaxial compression tests with acoustic emission (AE) monitoring were performed on CPB, for which the aggregate particles satisfied the Talbot grading theory. …”
