Mathematical Model of the Waste Plastic Management via ABC Fractional Order Derivative
International Journal of Mathematics and Mathematical SciencesPlastic waste can be broadly classified as recyclable and nonrecyclable wastes. The United Nations has set 17 goals of which Goal 14 refers to “Life below Water.” If plastic waste is not properly managed, it can pose a health hazard, including ...

Modeling the dynamics of the novel coronavirus using Caputo-Fabrizio derivative
Alexandria Engineering Journal, 2021 The virus that begins from Wuhan China, known as COVID-19 or coronavirus is still a huge panic for humans around the globe. The elimination of this virus from our society needs proper attentions to follows the rule suggested by World Health Organization (

A New Solution to the Fractional Black–Scholes Equation Using the Daftardar-Gejji Method
Mathematics, 2023 The main objective of this study is to determine the existence and uniqueness of solutions to the fractional Black–Scholes equation. The solution to the fractional Black–Scholes equation is expressed as an infinite series of converging Mittag-Leffler ...

Extendability of parallel sections in vector bundles [PDF]
, 2015 We address the following question: Given a differentiable manifold $M$ what are the open subsets $U$ of $M$ such that, for all vector bundles $E$ over $M$ and all linear connections $\nabla$ on $E$, any $\nabla$-parallel section in $E$ defined on $U ...

Fundamental properties of differential equations with dynamically defined delayed feedback [PDF]
, 2013 The increasing price of oil, global warming and rapid industrial growth has drawn much attention to renewable energy technologies over the last few decades. The total energy consumption is estimated to increase 1.4% per year globally.

Making big steps in trajectories [PDF]
, 2010 We consider the solution of initial value problems within the context of hybrid systems and emphasise the use of high precision approximations (in software for exact real arithmetic). We propose a novel algorithm for the computation of trajectories up to

Lipschitz Flow-box Theorem [PDF]
, 1962 A generalization of the Flow-box Theorem is proven. The assumption of a C1 vector field f is relaxed to the condition that f be locally Lipschitz continuous.

Multiple barrier-crossings of an Ornstein-Uhlenbeck diffusion in consecutive periods [PDF]
, 2020 We investigate the joint distribution and the multivariate survival functions for the maxima of an Ornstein-Uhlenbeck (OU) process in consecutive time-intervals. A PDE method, alongside an eigenfunction expansion is adopted, with which we first calculate

Inertial game dynamics and applications to constrained optimization [PDF]
, 2015 Aiming to provide a new class of game dynamics with good long-term rationality properties, we derive a second-order inertial system that builds on the widely studied "heavy ball with friction" optimization method.

Tuning PI controller in non-linear uncertain closed-loop systems with interval analysis [PDF]
, 2015 The tuning of a PI controller is usually done through simulation, except for few classes of problems, e.g., linear systems. With a new approach for validated integration allowing us to simulate dynamical systems with uncertain parameters, we are able to ...
