Wavelet collocation solution for fully wet semi-spherical porous fin
Partial Differential Equations in Applied MathematicsStudy Focus: In this paper, the thermal behavior of a semi-spherical fin embedded in a porous medium is examined. The heat transfer coefficient is considered to be temperature-dependent and follows a power-law relationship.Modeling Approach: Heat ...

A new Legendre wavelets decomposition method for solving PDEs
Malaya Journal of Matematik, 2014 In this paper, we present a novel technique based on the Legendre wavelets decomposition. The properties of Legendre wavelets are used to reduces the PDEs problem into the solution of ODEs system. To illustrate our results, two examples are studied using a special software package which implements the proposed algorithms.

A Generalization of Abel Inversion to non axisymmetric density distribution
, 2001 Abel Inversion is currently used in laser-plasma studies in order to estimate the electronic density $n_e$ from the phase-shift map $\delta \phi$ obtained via interferometry.

Residual permutation tests for feature importance in machine learning
British Journal of Mathematical and Statistical Psychology, EarlyView.Abstract Psychological research has traditionally relied on linear models to test scientific hypotheses. However, the emergence of machine learning (ML) algorithms has opened new opportunities for exploring variable relationships beyond linear constraints.

Electronic Journal of Differential Equations, 2015 A numerical method based on Legendre multi-wavelets is applied for solving Lane-Emden equations which form Volterra integro-differential equations. The Lane-Emden equations are converted to Volterra integro-differential equations and then are solved ...

Journal of Phycology, EarlyView.Abstract The distribution and connectivity of species around the globe are changing at a rapid pace. Increasing sea temperatures are a driving factor of changes in temperate macroalgal distributions. Southeast Australia is considered a global ocean‐warming hotspot, where macroalgal populations are predicted to decline significantly by 2100.
