Calculation of the spontaneous polarization for Pb1-xCaxTiO3 close to the tricritical point
(Taylor & Francis, 2016)We calculate the spontaneous polarization as a function of temperature for a mixed crystal of Pb1-xCaxTiO3 close to the tricritical pointdx (x = 0.4). This calculation of the spontaneous polarization is performed using the ... -
A class of second order nondifferentiable symmetric duality relations under generalized assumptions
(Journal Mathematics & Computer Science-JMCS, 2020)In this article, a pair of second-order nondifferentiable symmetric dual model in optimization problem is formulated over arbitrary cones. For a differentiable function, we consider the definition of strongly K-pseudobonvexity ... -
Data-Driven Surrogate-Assisted Optimization of Metamaterial-Based Filtenna Using Deep Learning
