Parameter estimation in a new chaotic memristive system using ions motion optimization
( Springer Verlag , 2019 , Article)In this paper, a new four-dimensional nonlinear oscillator is introduced. This oscillator is memristive and can exhibit chaotic behavior. A complete dynamical analysis is done on each parameter of this system by the help ... -
Effects of time-lagged meteorological variables on attributable risk of leishmaniasis in central region of Afghanistan
( Elsevier B.V. , 2019 , Article)Background Leishmaniasis remains one of the world's most neglected vector-borne diseases, affecting predominantly poor communities mainly in developing countries. Previous studies have shown that the distribution and ... -
Impact of magnetic dipole on a thermally stratified ferrofluid past a stretchable surface
( SAGE Publications Ltd , 2019 , Article)This article focuses on the characteristics of a magnetic dipole in a viscous ferrofluid induced by linear stretched surface. The analysis is disclosed by thermally stratified phenomenon and stagnation point. It is also ... -
Computational modeling and forensic analysis for terrorist airplane bombing: A case study
( Elsevier Ltd , 2019 , Article)The bombing of airliners has been a tactic used by terrorists during the past 40 years. Its prevention is a major priority by homeland security officials on a worldwide basis. In efforts to aid in the investigation of such ... -
Microscale Thermal Energy Transfer Over a Combined System of Thin Films: Analytical Approach
( Taylor and Francis Inc. , 2019 , Article)An analytical approach for the solution of the equation for phonon transport is presented for the combination thin films system. The transient phonon radiative transport model is considered and the combination of the silicon ... -
Convergence of RK-iterative process for generalized nonexpansive mappings in CAT(0) spaces
( World Scientific Publishing Co. Pte Ltd , 2019 , Article)In this paper, we introduce a new four-step iterative process and name it as RK-iterative process and prove some ?-convergence and strong convergence results using this process for generalized nonexpansive mappings in ... -
Dynamical transitions between equilibria in a dissipative Klein-Gordon lattice
( Academic Press Inc. , 2019 , Article)We consider the energy landscape of a dissipative Klein–Gordon lattice with a on-site potential. Our analysis is based on suitable energy arguments, combined with a discrete version of the Łojasiewicz inequality, in order ... -
Location charts based on ranked set sampling for normal and non-normal processes
( John Wiley and Sons Ltd , 2019 , Article)Control charts, based on ranked set sampling schemes, had been proposed recently for efficient monitoring of process location. All the proposals in the literature are based on the ideal assumption of normally distributed ... -
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 ... -
Hybrid isothermal model for the ferrohydrodynamic chemically reactive species
( Institute of Physics Publishing , 2019 , Article)A hybrid isothermal model for the homogeneous-heterogeneous reactions in ferrohydrodynamic boundary layer flow is established. The characteristics of Newtonian heating and magnetic dipole in a ferrofluid due to a stretchable ... -
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 ... -
Analysis of ferrite nanoparticles in the flow of ferromagnetic nanofluid
( Public Library of Science , 2018 , Article)Theoretical analysis has been carried out to establish the heat transport phenomenon of six different ferromagnetic MnZnFe2O4-C2H6O2 (manganese zinc ferrite-ethylene glycol), NiZnFe2O4-C2H6O2 (Nickel zinc ferrite-ethylene ... -
On the nonexistence of degenerate phase-shift multibreathers in Klein–Gordon models with interactions beyond nearest neighbors
( Elsevier B.V. , 2019 , Article)In this work, we study the existence of, low amplitude, phase-shift multibreathers for small values of the linear coupling in Klein–Gordon chains with interactions beyond the classical nearest-neighbor (NN) ones. In the ... -
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 ... -
Individual and network characteristic associated with hospital-acquired Middle East Respiratory Syndrome coronavirus
( Elsevier Ltd , 2019 , Article)Background: During outbreaks of infectious diseases, transmission of the pathogen can form networks of infected individuals connected either directly or indirectly. Methods: Network centrality metrics were used to characterize ... -
Simultaneous solutions for first order and second order slips on micropolar fluid flow across a convective surface in the presence of Lorentz force and variable heat source/sink
( Nature Publishing Group , 2019 , Article)This report presents the flow and heat transfer characteristics of MHD micropolar fluid due to the stretching of a surface with second order velocity slip. The influence of nonlinear radiation and irregular heat source/sink ... -
