Introduction: contrast sensitivity is one of the most important psychophysical tests that may be used for the evaluation of refractive state of eye and retinal image quality. Yellow vs. blue color contrast sensitivity may be more suitable in this regard. Materials and Methods: thirty myopic eyes were considered in this study. Yellow vs. blue color contrast sensitivity was evaluated under the sa...

In order to obtain a solution to an optimal control problem‎, ‎a numerical technique based on state-control parameterization method is presented‎. ‎This method can be facilitated by the computation of performance index and state equation via approximating the control and state variable as a function of time‎. ‎Several numerical examples are presented to confirm the analytical findings and illus...

In this paper, we state some results on product of operators with closed ranges and we solve the operator equation $TXS^*-SX^*T^*= A$ in the general setting of the adjointable operators between Hilbert $C^*$-modules, when $TS = 1$. Furthermore, by using some block operator matrix techniques, we nd explicit solution of the operator equation $TXS^*-SX^*T^*= A$.

The extension of the translated–consistent Peng–Robinson (tc-PR) equation state (EoS) to mixtures has been investigated. For this purpose, advanced EoS/aresE,γ mixing rules are used combine tc-PR EoS with residual part an activity coefficient model chosen among Wilson, nonrandom two-liquid (NRTL), and universal quasi-chemical (UNIQUAC) models. performances three resulting versions compared agai...

We have used a variational approach to calculate some thermodynamic properties of the quasi-one dimensional liquid 3He such as the energy, entropy, free energy, equation of state and heat capacity at finite temperature. We have employed the Lennard-Jones potential as the inter-atomic interaction. We have seen that the total energy increases by increasing both temperature and density....

High-pressure phase equilibrium and volumetric properties of highly asymmetric mixtures related to reservoir fluids are critical the development high-pressure high-temperature (HPHT) reservoirs. However, there is a lack relevant data accurate modeling tools. In this work, we prepared pseudo-binary methane (CH4) + stock tank oil (STO) systematically measured their densities at temperatures from ...
