In this article, we will investigate a retarded van Remote Emergency Pack der Pol-Duffing oscillator with multiple delays.At first, we will find conditions for which Bogdanov-Takens (B-T) bifurcation occurs around the trivial equilibrium of the proposed system.The center manifold theory has been used to extract second order normal form of the B-T b
Abstract The petrol truck routing problem is an important part of the petrol supply chain.This study focuses on determining routes for distributing petrol products from a depot to petrol stations with the objective of minimizing the total travel cost and the fixed cost required to use the trucks.We propose a mathematical model that considers petrol
As for a grid-connected PWM converter with LCL filter, harmonic current can flow freely into Sorting the grid-side inductor and filter capacitor, when the connected power grid is harmonically distorted.The fact lies in that the conventional control scheme has a little ability to suppress the grid current harmonics.Though the harmonics can be suppre
In the Creamer current study, a novel methylene blue (MB)-based colorimetric method for a quick, inexpensive, and facile approach for the determination of fouling intensity of reverse osmosis (RO) membrane has been reported.This technique is based on the interaction of MB with the organic foulants and shows the corresponding change in the colour in
