On a nonlinear second-order difference equation

open access: yesJournal of Inequalities and Applications, 2022
We study a nonlinear second-order difference equation which considerably extends some equations in the literature. Our main result shows that the difference equation is solvable in closed form. Some applications of the main result are also given.

A New Approach to Discrete Integration and Its Implications for Delta Integrable Functions

open access: yesMathematics, 2023
This research aims to develop discrete fundamental theorems using a new strategy, known as delta integration method, on a class of delta integrable functions. The νth-fractional sum of a function f has two forms; closed form and summation form.

A Mathematical Model for the Analysis of Jet Engine Fuel Consumption during Aircraft Cruise

open access: yesEnergies, 2021
In this paper we propose a mathematical model for the fuel consumption analysis during aircraft cruise. A closed-form formula that expresses the aircraft’s weight variation over time, and hence, the fuel flow rate, is obtained as a result. Furthermore, a
