A new hwma dispersion control chart with an application to wind farm data
( MDPI AG , 2020 , Article)Recently, a homogeneously weighted moving average (HWMA) chart has been suggested for the efficient detection of small shifts in the process mean. In this study, we have proposed a new one-sided HWMA chart to effectively ... -
A novel method to identify initial values of chaotic maps in cybersecurity
( MDPI AG , 2019 , Article)Chaos theory has applications in several disciplines and is focusing on the behavior of dynamical systems that are highly sensitive to initial conditions. Chaotic dynamics are the impromptu behavior displayed by some ... -
Application of artificial intelligence and gamma attenuation techniques for predicting gas-oil-water volume fraction in annular regime of three-phase flow independent of oil pipeline's scale layer
( MDPI AG , 2021 , Article)To the best knowledge of the authors, in former studies in the field of measuring volume fraction of gas, oil, and water components in a three-phase flow using gamma radiation technique, the existence of a scale layer has ... -
Common Fixed Point Results of Set Valued Maps for Aφ-Contraction and Generalized ϕ-Type Weak Contraction
( MDPI AG , 2019 , Article)The solutions for many real life problems may be obtained by interpreting the given problem mathematically in the form f(x)=x . One such example is that of the famous Borsuk–Ulam theorem in which, using some fixed point ... -
Construction of S-Box based on chaotic map and algebraic structures
( MDPI AG , 2019 , Article)The Advanced Encryption Standard (AES) is widely used in different kinds of security applications. The substitution box (S-box) is the main component of many modern symmetric encryption ciphers that provides confusion ... -
Entropy analysis and image encryption application based on a new chaotic system crossing a cylinder
( MDPI AG , 2019 , Article)Designing chaotic systems with specific features is a hot topic in nonlinear dynamics. In this study, a novel chaotic system is presented with a unique feature of crossing inside and outside of a cylinder repeatedly. This ... -
Extended rectangular b-metric spaces and some fixed point theorems for contractive mappings
( MDPI AG , 2019 , Article)In this paper, we introduce the class of extended rectangular b-metric spaces as a generalization of both rectangular metric and rectangular b-metric spaces. In addition, some fixed point results connected with certain ... -
Fixed point results using Ft-contractions in ordered metric spaces having t-property
( MDPI AG , 2019 , Article)In this paper, we prove the existence of fixed points of Ft-contraction mappings in partially ordered metric spaces not necessarily complete. We require that the ordered metric space has the t-property, which is a new ... -
Green synthesis of MNO nanoparticles using abutilon indicum leaf extract for biological, photocatalytic, and adsorption activities
( MDPI AG , 2020 , Article)We report the synthesis of MnO nanoparticles (AI-MnO NAPs) using biological molecules of Abutilon indicum leaf extract. Further, they were evaluated for antibacterial and cytotoxicity activity against different pathogenic ... -
On Phase-I monitoring of process location parameter with auxiliary information-based median control charts
( MDPI AG , 2020 , Article)A control chart is often used to monitor the industrial or services processes to improve the quality of the products. Mostly, the monitoring of location parameters, both in Phase I and Phase II, is done using a mean control ... -
PPF-dependent fixed point results for multi-valued ? F-contractions in Banach Spaces and Applications
( MDPI AG , 2019 , Article)The solutions for many real life problems is obtained by interpreting the given problem mathematically in the form of f (x) = x. One of such examples is that of the famous Borsuk-Ulam theorem, in which using some fixed ... -
Revisited carmichael's reduced totient function
( MDPI AG , 2021 , Article)The modified Totient function of Carmichael ?(.) is revisited, where important properties have been highlighted. Particularly, an iterative scheme is given for calculating the ?(.) function. A comparison between the Euler ... -
Single-Walled Carbon-Nanotubes-Based Organic Memory Structures
( MDPI AG , 2016 , Article)The electrical behaviour of organic memory structures, based on single-walled carbon-nanotubes (SWCNTs), metal–insulator–semiconductor (MIS) and thin film transistor (TFT) structures, using poly(methyl methacrylate) (PMMA) ... -
Statistical estimate of radon concentration from passive and active detectors in Doha
( MDPI AG , 2018 , Article)Harnessing knowledge on the physical and natural conditions that affect our health, general livelihood and sustainability has long been at the core of scientific research. Health risks of ionising radiation from exposure ... -
The generalized trust-region sub-problem with additional linear inequality constraints-Two convex quadratic relaxations and strong duality
( MDPI AG , 2020 , Article)In this paper, we study the problem of minimizing a general quadratic function subject to a quadratic inequality constraint with a fixed number of additional linear inequality constraints. Under a regularity condition, we ...
