Liquid K_(1-x) Rb_x binary alloys with various thermodynamical proportions of participating elements are investigated. The properties of thermodynamic interest are included in the study. The internal energy (Fint), Helmholtz free enrgy (FH) and ... see more

A class of vector optimization problems is considered. In particular, we reformulate this problem by means of a suitable vector variational inequality, involving the normal cone operator to the adjusted sublevel sets. Finally, this variational approach al... see more

A variational approach for ab initio handling of the Renner–Teller effect in six-atomic molecules with linear equilibrium geometry is elaborated. A very simple model Hamiltonian suitable for description of small-amplitude bending vibrations in ? electroni... see more

Background: This work incorporates results that help to understand how to favour the development of variational thinking and language in students of middle school education. Objective: to relate variational thinking with some preliminary notions of calcul... see more

The aim of this paper is the study of variational-hemivariational inequalities with nonhomogeneous Neumann boundary condition. Sufficient conditions for the existence of a whole sequence of solutions which is either unbounded or converges to zero are prov... see more

In this paper, we study an economic equilibrium problem under uncertainty using a variational approach. In particular, the equilibrium conditions involve the maximization of agents preferences, which are supposed to be not complete. Hence, we will re... see more

In this paper, A new method proposed and coined by the authors as the natural variational iteration  transform method(NVITM) is utilized to solve linear and nonlinear systems of fractional differential equations. The new method is a combination of na... see more

The aim of this paper is to evaluate the theoretical efficiency of optimal propellers by means of a variational approach; non classical propellers are included in the analysis. A solution to the optimum rotor problem, in the context of propeller vortex th... see more

In this research, the susceptible–infected–recovered (SIR) model of dengue fever is considered. We have implemented two analytical techniques, namely the variational iteration method (VIM) and the homotopy perturbation method (HPM) for solving the SIR mod... see more
