Double ARA–Generalized Laplace Method for Solving (2 +1)–Dimensional Nonlinear Singular Pseudoparabolic Equations Rania Saadeh, Abdelilah Kamal. H. Sedeeg, Ahmad Qazza, Osama Ala′yed Journal of Applied Mathematics, 2026 This study presents a novel triple integral transformation, called the double ARA–generalized Laplace transform (DAGLT), and applies it to solve (2 + 1)–dimensional singular pseudoparabolic equations in both linear and nonlinear forms. The work begins by outlining the fundamental definitions, theorems, and characteristics of the single ARA and generalized Laplace transforms, then proceeds to unify them into a single framework (DAGLT). Detailed derivations of the core properties linearity, shifting, and partial derivative transforms demonstrate the theoretical soundness and broad applicability of DAGLT. Utilizing the Adomian decomposition method merged with this new transform, the paper presents an efficient procedure for obtaining closed‐form or series‐based solutions to challenging singular pseudoparabolic partial differential equations. Several illustrative examples showcase the effectiveness of the proposed technique, confirming that its solutions align with known results in the literature. The main advantages of the method are that it can handle singularities, and it improves the convergence. This study is promising for dealing with different models of multidimensional partial differential equations that arise in physical science and models.
Exploration of a New Approach Related to Atangana-Baleanu Derivatives for Solving Fractional Partial Differential Equations Rania Saadeh, Ahmad Qazza, Abdelilah Kamal H. Sedeeg, Ghassan Abufoudeh International Journal of Mathematical Engineering and Management Sciences, 2025 This paper explores the application of fractional calculus to solve fractional partial differential equations (FPDEs) using the Sawi transform in combination with the Atangana-Baleanu fractional derivative. The Atangana-Baleanu derivative, formulated in both Caputo and Riemann-Liouville senses, offers a powerful tool for modeling memory and hereditary properties in complex physical systems. We extend the Sawi transform’s operational framework to efficiently handle FPDEs by deriving new properties and convolution theorems relevant to the fractional derivatives. The combination of the Sawi transform with the homotopy perturbation method yields a novel approach, termed the Sawi-Transform-Homotopy Perturbation Method, which facilitates the analytical solution of nonlinear FPDEs. The proposed method was validated using fractional Kolmogorov and Rosenau-Hyman equations, achieving exact solutions in some cases and series solutions with rapid convergence in others. Numerical results demonstrated a reduction in computational complexity by approximately 30% compared to traditional methods, highlighting its efficiency and accuracy. This work underscores the utility of fractional calculus in solving real-world problems and advances analytical techniques for solving FPDEs using modern fractional operators.
A comparative analysis of the impact of different treatments on Luffa Cylindrica fiber tensile properties Rania Saadeh, Ayman A. Dawod, Ibrahim Mahariq, Ahmad Qazza, Abdelkader Khentout, et al. Plos One, 2025 In recent years, there has been a growing demand for environmentally friendly materials as alternatives to synthetic fibers, which pose significant environmental hazards due to their non-biodegradability. Natural fibers, such as Luffa Cylindrica, have gained attention due to their sustainability, lightweight properties, and biodegradability. However, their poor mechanical performance in composite applications limits their widespread use. The novelty of this study lies in the exploration of various treatments aimed at improving the tensile properties of Luffa Cylindrica fibers (LCFs), a relatively under-explored natural fiber. The research investigates the effects of immersion treatments in mineral water, seawater, vinegar (CH₃COOH), sodium bicarbonate (NaHCO₃), and ethanol (C₂H₆O) on the tensile strength, surface morphology, and absorption properties of these fibers. The study highlights that untreated LCFs exhibit superior tensile strength (5.59 MPa) compared to treated fibers. Additionally, the statistical analysis utilizing two-parameter Weibull distribution offers novel insights into the mechanical properties of treated LCFs, confirming significant variations in fiber behavior with different treatments. This study contributes to the understanding of surface modifications that enhance the performance of Luffa Cylindrica fibers in composite materials, a promising step towards their industrial application.
