A new LQP alternating direction method for solving variational inequality problems with separable structure
( Taylor and Francis Ltd. , 2016 , Article)We presented a new logarithmic-quadratic proximal alternating direction scheme for the separable constrained convex programming problem. The predictor is obtained by solving series of related systems of non-linear equations ... -
A New Memristive Chaotic System with a Plane and Two Lines of Equilibria
( World Scientific , 2021 , Article)A new 4D memristive chaotic system with an infinite number of equilibria is proposed via exhaustive computer search. Interestingly, such a new memristive system has a plane of equilibria and two other lines of equilibria. ... -
A new numerical method for heat equation subject to integral specifications
( International Scientific Research Publications , 2016 , Article)We develop a numerical technique for solving the one-dimensional heat equation that combine classical and integral boundary conditions. The combined Laplace transform, high-precision quadrature schemes, and Stehfest inversion ... -
A New System with a Self-Excited Fully-Quadratic Strange Attractor and Its Twin Strange Repeller
( World Scientific , 2021 , Article)In nonlinear dynamics, the study of chaotic systems has attracted the attention of many researchers around the world due to the exciting and peculiar properties of such systems. In this regard, the present paper introduces ... -
A New Version of Black Scholes Equation Presented by Time-Fractional Derivative
( Springer International Publishing , 2018 , Article)In this article, a new time-fractional-order Black–Scholes equation has been derived. In this derivation, the asset price satisfies in a fractional-order stochastic differential equation. Here, the effect of trend memory ... -
A non-parametric double homogeneously weighted moving average control chart under sign statistic
( John Wiley and Sons Ltd , 2021 , Article)In practical situations, the underlying process distribution sometimes deviates from normality and their distribution is partially or completely unknown. In that instance, rather than staying with/depending on the conventional ... -
A note on the Ramsey numbers for theta graphs versus the wheel of order 5
( Kalasalingam University , 2018 , Article)The study of exact values and bounds on the Ramsey numbers of graphs forms an important family of problems in the extremal graph theory. For a set of graphs S and a graph F, the Ramsey number R(S,F) is the smallest positive ... -
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 ... -
A one-step implicit iterative method for two finite families of asymptotically nonexpansive mappings in a hyperbolic space
( Springer Verlag , 2018 , Article)We introduce a one-step implicit iterative method for two finite families of asymptotically nonexpansive mappings in a hyperbolic space and use it to approximate common fixed points of these families. The results presented ... -
A penalty decomposition algorithm for the extended mean-variance-CVaR portfolio optimization problem
( World Scientific , 2023 , Article)In this paper, we study mean-variance-Conditional Value-At-Risk (CVaR) portfolio optimization problem with short selling, cardinality constraint and transaction costs. To tackle its mixed-integer quadratic optimization ... -
A point symmetry based method for transforming ODEs with three-dimensional symmetry algebras to their canonical forms
( Elsevier Inc. , 2016 , Article)We provide an algorithmic approach to the construction of point transformations for scalar ordinary differential equations that admit three-dimensional symmetry algebras which lead to their respective canonical forms. -
