In recent years, the demand for the use of drones has increased, which has led to many problems, including the problem of landing, and many researchers have developed protocols and applications for the landing of autonomous ...

The main concern of this dissertation is concentrated on numerically solving the integrodelay differential equations with variable coefficients on a half-line, proposing a matrixcollocation method based on ortho-exponential ...

Abstract After introducing basic concepts in fuzzy mathematics, we focused our attention to solve the linear fuzzy Fredholm integral equation of the second kind by Adomian method. Using parametric form of fuzzy numbers ...

Di erential equations were invented by Newton (1642-1727). It is the beginning of modern physics and the use of analysis to solve the law of universal gravitation leading to the ellipsity of the orbits of the planets in ...

Most of problems encountered can be modelled mathematically, but these models require assumptions that are sometimes too restrictive, making application to the real world difficult. Real-world problems must take into ...

Ordinary differential equations play a major and prominent role in all fields of science due to their wide of applications in physics, engineering, and biology as an approximate model or as a result of physical laws for ...

In this thesis, we rst gave essential information such as de nitions, lemmas, and theorems used in our study. Second, we have presented the averaging theory for computing limit cycles for the systems, focus-focus, ...

In this work, we have studied the functions and polynomials of Bessel with giving some theories and properties and mentioned some of their applications, where they were employed in the solutions of integral and differential ...
