Improved Adaptive Sliding Mode Control Using Quasi-Convex Functions and Neural Network-Assisted Time-Delay Estimation for Robotic Manipulators [PDF]

open access: yesSensors
This study presents an adaptive sliding mode control strategy tailored for robotic manipulators, featuring a quasi-convex function-based control gain and a time-delay estimation (TDE) enhanced by neural networks.

ON INEQUALITIES RELATED TO SOME QUASI-CONVEX FUNCTIONS

open access: yesПроблемы анализа, 2015
Estimations of errors in inequalities related to some quasi-convex functions in literature are simplified. Two new general inequalities for functions whose n-th derivatives for any positive integer n in absolute values are quasi-convex have been ...

Quasi Semi and Pseudo Semi (p,E)-Convexity in Non-Linear Optimization Programming

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2023
The class of quasi semi -convex functions and pseudo semi -convex functions are presented in this paper by combining the class of -convex functions with the class of quasi semi -convex functions and pseudo semi -convex functions, respectively.

Quasi‐convex univalent functions [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1979
In this paper, a new class of normalized univalent functions is introduced. The properties of this class and its relationship with some other subclasses of univalent functions are studied. The functions in this class are close‐to‐convex.

On co-ordinated quasi-convex functions [PDF]

open access: yesCzechoslovak Mathematical Journal, 2012
In this paper, we give some definitions on quasi-convex functions and we prove inequalities contain J-quasi-convex and W-quasi-convex functions. We give also some inclusions.

New quantum integral inequalities for some new classes of generalized ψ-convex functions and their scope in physical systems

open access: yesOpen Physics, 2021
In the present study, two new classes of convex functions are established with the aid of Raina’s function, which is known as the ψ-s-convex and ψ-quasi-convex functions. As a result, some refinements of the Hermite–Hadamard (ℋℋ{\mathcal{ {\mathcal H} {\

On the Convergence Rate of Quasi-Newton Methods on Strongly Convex Functions with Lipschitz Gradient

open access: yesMathematics, 2023
The main results of the study of the convergence rate of quasi-Newton minimization methods were obtained under the assumption that the method operates in the region of the extremum of the function, where there is a stable quadratic representation of the ...

Inclusion Relations for Dini Functions Involving Certain Conic Domains

open access: yesFractal and Fractional, 2022
In recent years, special functions such as Bessel functions have been widely used in many areas of mathematics and physics. We are essentially motivated by the recent development; in our present investigation, we make use of certain conic domains and ...
