Due to the uncertainties from modeling, manufacturing, and working environments, many
vibration active control systems usually show dynamic uncertain properties. Hence structural …

In this paper, we formulate a new set of sufficient conditions for the approximate
controllability of fractional evolution stochastic integrodifferential delay inclusions of order …

In this paper, we investigate the approximate controllability for fractional integrodifferential
inclusions of order r∈(1, 2) in Banach space with sectorial operators. In particular, we obtain …

In this article, we mainly focus on the existence and approximate controllability results for the
fractional semilinear impulsive control system of order r∈(1, 2). We consider two different …

In this paper, a new mathematical model for dual variants of COVID-19 and HIV co-infection
is presented and analyzed. The existence and uniqueness of the solution of the proposed …

The goal of this study is to propose the existence results for the Sobolev-type Hilfer fractional
integro-differential systems with infinite delay. We intend to implement the outcomes and …

This work analyzes the existence and partial-approximate controllability of non-local semi-
linear systems involving two Riemann-Liouville fractional derivatives without Lipschitz …

This manuscript concerns the approximate controllability results in Hilbert space of Hilfer
fractional differential inclusions. We show that the Hilfer fractional neutral differential …

The objective of this paper is to investigate the optimal control results for Sobolev-type
fractional stochastic Volterra-Fredholm integrodifferential systems of order ϑ∈(1, 2) with …

As a section on improving the energy efficiency and thermal efficiency of convection dryers,
a different airflow distribution system in the convection dryer was established. The grape …
