Abstract

Accident prediction models are mathematical expressions or algorithms used to determine the causal factors for road accidents and road safety engineers are using these models, as well. Modelling this kind of accident is quite challenging and required good quality of data. The results of the artificial neural network model, Gaussian processes model, and support vector machine model are compared for vulnerable road accident frequency in this study. The accident frequency dataset comprises 218 records, with 146 designated for training purposes and 72 reserved for testing. The model's accuracy was contingent on: the mean absolute error, root mean square error and coefficient of correlation. The findings suggest that for predicting the vulnerable road user accidents on roads, the artificial neural network gives better correlation results as (0.912) that the support vector machine (0.879) and Gaussian processes (0.853).

13. On extrapolatory mixed quadrature rule for approximate evaluation of real definite integrals.

Subjects
*DEFINITE integrals
Abstract

This study employs Richardson extrapolation on mixed quadrature rule which is imbraided by Lobatto-4-point rule (RLA(f)) with Gauss-Legendre-3-point rule (RGL3 (f)) to form the extrapolatory quadrature rule (RRLAG13 (f)) Of precision nine. The current rule is numerically verified with six test problems and the bound for the error is resolved with suitable examples. [ABSTRACT FROM AUTHOR]

18. Curious Catalytic Characteristics of Al–Cu–Fe Quasicrystal for De/Rehydrogenation of MgH2

Abstract

The present study reports the curious catalytic action of a new class of catalyst, quasicrystal of Al65Cu20Fe15on de/rehydrogenation properties of magnesium hydride (MgH2). Catalyzed through this catalyst, the onset desorption temperature of MgH2gets reduced significantly from ∼345 °C (for ball-milled MgH2) to ∼215 °C. A more dramatic effect of the above catalyst has been observed on rehydrogenation. Here, 6.00 wt % of hydrogen storage capacity is observed in just 30 s at 250 °C. Improved rehydrogenation kinetics has been found even at lower temperatures of 200 and 150 °C by absorbing ∼5.50 and ∼5.40 wt % of H2, respectively, within 1 min and ∼5.00 wt % at 100 °C in 30 min. These are some of the lowest desorption temperatures and rehydrogenation kinetics obtained for MgH2through any other known catalyst. The storage capacity of MgH2catalyzed with the leached version of Al65Cu20Fe15quasicrystalline alloy degrades negligibly even after 51 cycles of de/rehydrogenation. The feasible reason for catalytic action has been described and discussed on the basis of structural, microstructural, Fourier transform infrared, and X-ray photoelectron spectroscopic studies.
