Assessing the change of ambient air quality patterns in Jiangsu Province of China pre-to post-COVID-19.
Uzair Aslam Bhatti,Zeeshan Zeeshan,Mir Muhammad Nizamani,Sibghatullah Bazai,Zhaoyuan Yu,Linwang Yuan +5 more
TL;DR: Wang et al. as mentioned in this paper investigated the change in air pollution (focusing on the air quality index (AQI), six ambient air pollutants nitrogen dioxide (NO2), ozone (O3), sulphur dioxide (SO2), carbon monoxide (CO), particulate matter with aerodynamic diameters ≤10 μm (PM10) and ≤2.5 μm(PM2.
Journal ArticleDOI
Hybrid Watermarking Algorithm Using Clifford Algebra With Arnold Scrambling and Chaotic Encryption
Uzair Aslam Bhatti,Zhaoyuan Yu,Jingbing Li,Saqib Ali Nawaz,Anum Mehmood,Kun Zhang,Linwang Yuan +6 more
TL;DR: A Quaternion Fourier transform (QFT) based algorithm, based on Arnold transform and chaotic encryption, is proposed in this paper, which proposes a digital watermarking algorithm that resists geometric attacks by using color images as carriers.
Journal ArticleDOI
CAUSTA: Clifford Algebra-based Unified Spatio-Temporal Analysis
TL;DR: In this paper, a unified spatio-temporal data model and hierarchical spatial index are constructed by linking basic data objects, like pointclouds and Spatio-Temporal Hyper Cubes of different dimensions, within the multivector structure of Clifford algebra.
Journal ArticleDOI
Geographic scenario: a possible foundation for further development of virtual geographic environments
Guonian Lü,Min Chen,Linwang Yuan,Liangchen Zhou,Yongning Wen,Mingguang Wu,Bin Hu,Zhaoyuan Yu,Songshan Yue,Yehua Sheng +9 more
TL;DR: It is empirically found that geographic scene provides a suitable organization schema to support geo-visualization, geo-simulation, and geo-collaboration in virtual geographic environments.
Journal ArticleDOI
Time Series Analysis and Forecasting of Air Pollution Particulate Matter (PM 2.5 ): An SARIMA and Factor Analysis Approach
Uzair Aslam Bhatti,Yuhuan Yan,Mingquan Zhou,Sajid Ali,Aamir Hussain,Huo Qingsong,Zhaoyuan Yu,Linwang Yuan +7 more
TL;DR: The study reveals that the particulate matter in the Lahore season (PM2.5, PM10) exceeds Pakistan’s National Environmental Quality Standards (NEQS) and correlation study suggests the positive correlation between the particulates matter and other mass concentration particles like Ozone, Nitrogen Oxide, Sulphur Dioxide, and SO2.
