• Existence and uniqueness of solutions of some general fuzzy partial hyperbolic functional differential equationsExistence and uniqueness of solutions of some general fuzzy partial hyperbolic functional differential equations

    Abstract. In this paper, we investigate the existence and uniqueness of fuzzy solution for a class of general hyperbolic equations with state-dependent delays. We will prove the well-posedness of problem doesn’t depend on the domain and boundary data as well as initial data. Our method is based on Banach fixed point theorem in completely new we...

  • Optimization of laminated composite plates for maximum biaxial buckling loadOptimization of laminated composite plates for maximum biaxial buckling load

    Abstract: This paper proposes an optimization procedure for maximization of the biaxial buckling load of laminated composite plates using the gradient-based interior-point optimization algorithm. The fiber orientation angle and the thickness of each lamina are considered as continuous design variables of the problem. The effect of the number of ...

  • Machine learning representation for atomic forces and energiesMachine learning representation for atomic forces and energies

    Abstract: We present machine learning models for fast estimating atomic forces and energies. In our method, the total energy of a system is approximated as the summation of atomic energy which is the interaction energy with its surrounding chemical environment within a certain cutoff radius. Atomic energy is decomposed into two-body terms which ...

  • Optical back-propagation for nonlinear compensation in OFDM-based long range-passive optical networksOptical back-propagation for nonlinear compensation in OFDM-based long range-passive optical networks

    Abstract: In direct-detection optical OFDM system, the nonlinear impairment is the key factor that limits the system performance. The back-propagation techniques in digital and optical domains have been proposed to compensate the nonlinear effects, however they can be unsuitable for long-range passive optical networks (LR-PONs) due to their impl...

  • Impact of parallel computing on study of time evolution of a quantum impurity system in response to a quenchImpact of parallel computing on study of time evolution of a quantum impurity system in response to a quench

    Abstract: In an arbitrary system subjected to a quench or an external field that varies the system parameters, the degrees of freedom increases double in comparison to that of an isolated system. In this study, we consider the quantum impurity system subjected to a quench, and measure the corresponding time-evolution of the spectral function, wh...

  • Gelation of Anisotropic Colloids with Short-Range AttractionGelation of Anisotropic Colloids with Short-Range Attraction

    Abstract: Colloidal gels are space-spanning networks that form solids at dilute particle volume fractions. The kinetic process of gelation is central to understand the flow of complex fluids. Here, we report a simulation study of colloidal gelation of anisotropic colloids with attractive LennardJones potential. These forces quasi-model the critic...
