Using a Gaussian model to estimate the level of particle matter concentration on paved and unpaved roads in urban environment: A case study

Journal of Air Pollution and Health, 2023
Introduction: In both developed and developing countries, re-suspension of dust particles along the road owing to tire and brake wear is the most common source of Particulate Matters (PM) pollution in metropolitan areas.

Mapping of major tectonic lineaments across Cameroon using potential field data

Earth, Planets and Space, 2022
The cartography of lineaments across a territory can be optimized using geophysical potential field data. In this study, land gravity and EMAG2 (Earth Magnetic Anomaly Grid) data were simultaneously used to identify and characterize the major lineaments ...

Experimental study on the effect of load and air+gas/fuel ratio on the performances, emissions and combustion characteristics of diesel–LPG fuelled single stationary ci engine

Engineering Reports, 2023
Due to the issue of combustion stability when using natural gas and the problem of knocking when using both natural gas and hydrogen, liquefied petroleum gas (LPG) is then a good candidate to use for the dual‐fuel concept since it has been proven to be a

A Crank–Nicolson Compact Difference Method for Time-Fractional Damped Plate Vibration Equations

Axioms, 2022
This paper discusses the Crank–Nicolson compact difference method for the time-fractional damped plate vibration problems. For the time-fractional damped plate vibration equations, we introduce the second-order space derivative and the first-order time ...
