Unveiling the Predictive Capabilities of Machine Learning in Air Quality Data Analysis: A Comparative Evaluation of Different Regression Models

引用

Open Journal of Air Pollution 2023年第4期12卷 142-159页

作者： Mosammat Mustari Khanaum Md Saidul Borhan Farzana Ferdoush mohammed Ali Nause Russel mustafa Murshed Department of Civil Construction and Environmental Engineering North Dakota State University Fargo USA Texas Department of Transportation Maintenance Division Austin USA Department of Arts and Sciences Ahsanullah University of Science and Technology Dhaka Bangladesh School of Social & Environmental Sustainability University of Glasgow Glasgow UK Department of Economics Andrew Young School of Policy Studies Georgia State University Atlanta USA

Air quality is a critical concern for public health and environmental regulation. The Air Quality Index (AQI), a widely adopted index by the US Environmental Protection Agency (EPA), serves as a crucial metric for reporting site-specific air pollution levels. Accurately predicting air quality, as measured by the AQI, is essential for effective air pollution management. In this study, we aim to identify the most reliable regression model among linear discriminant analysis (LDA), quadratic discriminant analysis (QDA), logistic regression, and K-nearest neighbors (KNN). We conducted four different regression analyses using a machine learning approach to determine the model with the best performance. By employing the confusion matrix and error percentages, we selected the best-performing model, which yielded prediction error rates of 22%, 23%, 20%, and 27%, respectively, for LDA, QDA, logistic regression, and KNN models. The logistic regression model outperformed the other three statistical models in predicting AQI. Understanding these models' performance can help address an existing gap in air quality research and contribute to the integration of regression techniques in AQI studies, ultimately benefiting stakeholders like environmental regulators, healthcare professionals, urban planners, and researchers.

Collision mitigation and vehicle transportation safety using integrated vehicle dynamics control systems

引用

Journal of Traffic and Transportation Engineering(English Edition) 2017年第1期4卷 41-60页

作者： mustafa Elkady Ahmed Elmaralebi John Maclntyre mohammed Alhariri School of Engineering Lebanese International UniversityBeirutLebanon Faculty of Engineering Ain Shams UniversityCairoEgypt Faculty of Engineering and Advanced Manufacturing University of SunderlandSunderlandSR6 ODDUK

The aim of this paper is to investigate the effect of vehicle dynamics control systems （VDCS） on both the collision of the vehicle body and the kinematic behaviour of the ve- hicle＇s occupant in case of offset frontal vehicle-to-vehicle collision. A unique 6-degree-of- freedom （6-DOF） vehicle dynamics/crash mathematical model and a simplified lumped mass occupant model are developed. The first model is used to define the vehicle body crash parameters and it integrates a vehicle dynamics model with a vehicle front-end structure model. The second model aims to predict the effect of VDCS on the kinematics of the occupant. It is shown from the numerical simulations that the vehicle dynamics/crash response and occupant behaviour can be captured and analysed quickly and accurately. Yurthermore, it is shown that the VDCS can affect the crash characteristics positively and the occupant behaviour is improved.

AIM：To investigate the association between single nucleotide polymorphisms （SNPs） in the LOXL1 gene with exfoliation syndrome/glaucoma （XFS/XFG） among ***：Sixty-one patients with XFS/XFG and 59 healthy control individuals were recruited in the *** were diagnosed with XFS/XFG using standard clinical examination techniques. The exonic rs1048661SNP and the intronic rs2165241 SNP in LOXL1 gene were genotyped using sequencing technique. Allele and genotype frequencies were compared between cases and controls using Chi-square ***：The G allele of the rs1048661 SNP and the T allele of the rs2165241 SNP were common in the sample with frequencies of 86.4% and 81.4%, respectively. In addition, there were no significant differences in the genotypic and allelic distributions between patients and controls for rs1048661 SNP （P=0.770, OR=1.21, 95%CI：0.56-2.60） and for rs2165241 SNP （P=0.605, OR=1.12,95%CI：0.59-2.09）. In addition, no significant associations were found between haplotypes of the examined SNPs and XFS/XFG in the sample （P〉0.05）. CONCLUSION：Variations in LOXL1 gene may not be associated with XFS/XFG in the Jordanian *** studies are required to confirm the current findings.

Using Two Levels DWT with Limited Sequential Search Algorithm for Image Compression

引用

Journal of Signal and Information Processing 2012年第1期3卷 51-62页

作者： mohammed mustafa Siddeq Software Engineering Department Technical College Kirkuk Iraq

In this paper introduce new idea for image compression based on the two levels DWT. The low-frequency sub-band is minimized by using DCT with the Minimize-Matrix-Size-Algorithm, which is converting the AC-coefficients into array contains stream of real values, and then store the DC-coefficients are stored in a column called DC-Column. DC-Column is transformed by one-dimensional DCT to be converted into T-Matrix, then T-Matrix compressed by RLE and arithmetic coding. While the high frequency sub-bands are compressed by the technique;Eliminate Zeros and Store Data (EZSD). This technique eliminates each 8 × 8 sub-matrix contains zeros from the high frequencies sub-bands, in another hands store nonzero data in an array. The results of our compression algorithm compared with JPEG2000 by using four different gray level images.
