Sliding mode control law for a variable speedwind turbine
(WSEAS, 2011)
Modern wind turbines are designed in order to work in variable speed operations. To perform this task, wind turbines are provided with adjustable speed generators, like the double feed induction generator. One of the main ...
Adaptive variable structure control law for a variable speed wind turbine
(WSEAS, 2011)
The efficiency of the wind power conversions systems can be greatly improved using an appropriate control algorithm. In this work, an adaptive robust control for a doubly feed induction generator drive for variable speed ...
Imaging Ultrasound Propagation Using the Westervelt Equation by the Generalized Kudryashov and Modified Kudryashov Methods
(MDPI, 2022-11-21)
This article deals with the study of ultrasound propagation, which propagates the mechanical vibration of the molecules or of the particles of a material. It measures the speed of sound in air. For this reason, the third-order ...
An Intelligent Platform for Software Component Mining and Retrieval
(MDPI, 2023-01-03)
The development of robotic applications necessitates the availability of useful, adaptable, and accessible programming frameworks. Robotic, IoT, and sensor-based systems open up new possibilities for the development of ...
Solution to Integral Equation in an O-Complete Branciari b-Metric Spaces
(MDPI, 2022-12-13)
In this paper, we prove fixed point theorem via orthogonal Geraghty type α-admissible contraction map in an orthogonal complete Branciari b-metric spaces context. An example is presented to strengthen our main result. We ...
New Results for Multivalued Mappings in Hausdorff Neutrosophic Metric Spaces
(MDPI, 2022-12-13)
The fundamental goal of this paper is to derive common fixed-point results for a sequence of multivalued mappings contained in a closed ball over a complete neutrosophic metric space. A basic and distinctive procedure has ...
On an Extended Time-Varying Beverton–Holt Equation Subject to Harvesting Monitoring and Population Excess Penalty
(Hindawi, 2023-04)
This paper considers a more general eventually time-varying Beverton–Holt equation for species evolution which can include a harvesting action and a penalty for overpopulation numbers. The harvesting action may be positive ...
Existence of a solution for a nonlinear integral equation by nonlinear contractions involving simulation function in partially ordered metric space
(Vilnius University Press, 2023-05)
In a recent paper, Khojasteh et al. presented a new collection of simulation functions, said

-contraction. This form of contraction generalizes the Banach contraction and makes different
types of nonlinear contractions. ...
Existence of Best Proximity Point in O-CompleteMetric Spaces
(MDPI, 2023-08-09)
In this work, we prove the existence of the best proximity point results for ⊥-contraction (orthogonal-contraction) mappings on an O-complete metric space (orthogonal-complete metric space). Subsequently, these existence ...
Hyperstability of Linear Feed-Forward Time-Invariant Systems Subject to Internal and External Point Delays and Impulsive Nonlinear Time-Varying Feedback Controls
(MDPI, 2023-07-07)
This paper investigates the asymptotic hyperstability of a single-input–single-output closed-loop system whose controlled plant is time-invariant and possesses a strongly strictly positive real transfer function that is ...
