Simulation of the Spatiotemporal Distribution of PM2.5 Concentration Based on GTWR-XGBoost Two-Stage Model: A Case Study of Chengdu Chongqing Economic Circle

open access: yesAtmosphere, 2023
Natural environmental factors and human activity intensity factors, the two main factors that affect the spatial and temporal distribution of PM2.5 concentration near the surface, have different mechanisms of action on PM2.5 concentration. In this paper,

PM2.5 concentration assessment based on geographical and temporal weighted regression model and MCD19A2 from 2015 to 2020 in Xinjiang, China.

open access: yesPLoS ONE, 2023
PM2.5 is closely linked to both air quality and public health. Many studies have used models combined with remote sensing and auxiliary data to inverse a large range of PM2.5 concentrations. However, the data's spatial resolution is limited.

Assessment model of rainwater resource utilization and influencing factors in arid and semiarid areas

open access: yesNatural Resource Modeling, Volume 36, Issue 2, May 2023., 2023
Abstract Arid and semiarid areas generally face problems of natural resource degradation. In this paper, two indicators are proposed to characterize the utilization of rainwater: rainwater resource utilization quantity (RRU, mm) and rainwater resource utilization rate (RRUR, dimensionless ratio). A spatiotemporal assessment model (rainwater utilization

A Geographically Temporal Weighted Regression Approach with Travel Distance for House Price Estimation

open access: yesEntropy, 2016
Previous studies have demonstrated that non-Euclidean distance metrics can improve model fit in the geographically weighted regression (GWR) model. However, the GWR model often considers spatial nonstationarity and does not address variations in local ...

Evolution of smart grids towards the Internet of energy: Concept and essential components for deep decarbonisation

open access: yesIET Smart Grid, Volume 6, Issue 1, Page 86-102, February 2023., 2023
In this study, we present a detailed overview regarding the evolution of smart grids towards modern Internet energy systems. We present the essential components of Internet of Energy (IoE) for decarbonisation in the future of energy sector. Also, some models and equations are provided to evaluate the effects of IoE and the misallocation of energy on ...

Local Spatial Analysis of the Crash Frequency of Food Delivery Motorcyclists vs. Nondelivery Motorcyclists in relation to Points of Interest

open access: yesJournal of Advanced Transportation, Volume 2023, Issue 1, 2023., 2023
The COVID‐19 pandemic has increased the demand for online food delivery services (OFDS), leading to an increase in related crashes over the last few years. While recent studies have focused on nonmotorised vehicles (such as bicycles or e‐bikes), few researchers have examined the role of motorcycles and the possible spatial relationships with various ...
