Explicit limit cycles of a family of polynomial differential systems

Electronic Journal of Differential Equations, 2017
We consider the family of polynomial differential systems $$\displaylines{ x' = x+( \alpha y-\beta x) (ax^2-bxy+ay^2) ^{n}, \cr y' = y-( \beta y+\alpha x) (ax^2-bxy+ay^2) ^{n}, }$$ where a, b, $\alpha $, $\beta $ are real constants and n is ...

Characterization of Droplet Formation in Ultrasonic Spray Coating: Influence of Ink Formulation Using Phase Doppler Anemometry and Machine Learning

Advanced Materials Technologies, EarlyView.
This study explores how machine learning models, trained on small experimental datasets obtained via Phase Doppler Anemometry (PDA), can accurately predict droplet size (D32) in ultrasonic spray coating (USSC). By capturing the influence of ink complexity (solvent, polymer, nanoparticles), power, and flow rate, the model enables precise droplet control

Some properties of solutions to polynomial systems of differential equations

Electronic Journal of Differential Equations, 2005
In [7] and [8], Parker and Sochacki considered iterative methods for computing the power series solution to ${f y' = G circ y}$ where ${f G}$ is a polynomial from $mathbb{R}^n$ to $mathbb{R}^n$, including truncations of Picard iteration.

Limit cycles bifurcating from the periodic orbits of the weight-homogeneous polynomial centers of weight-degree 3

Electronic Journal of Differential Equations, 2018
In this article we obtain two explicit polynomials, whose simple positive real roots provide the limit cycles which bifurcate from the periodic orbits of a family of polynomial differential centers of order 5, when this family is perturbed inside the ...
