Numerical Simulation and Parametric Reduced Order Modeling of the Natural Convection of Water-Copper Nanofluid

In this article, a coupled computational framework is presented for the numerical simulation of mass transfer under the effects of natural convection phenomena in a field contains water-copper Nano-fluid. This CFD model is build up based on accurate algorithms for spatial derivatives and time integration. The spatial derivatives have been calculated using first order upwind and second order cen...

Introduction to Krylov Subspace Methods in Model Order Reduction

In recent years, Krylov subspace methods have become popular tools for computing reduced order models of high order linear time invariant systems. The reduction can be done by applying a projection from high order to lower order space using the bases of some subspaces called input and output Krylov subspaces. The aim of this paper is to give an introduction into the principles of Krylov subspac...

A Mathematical Programing Model of Budget Allocation for Development Disparities Reduction among Iran Provinces

The issues of disparities, regional imbalance development and attempt to reducing development disparities among various regions have been attracted considerable attention among researchers, planners and policy makers. In this regard, this study employs a mathematical programing model for budget resources allocation among Iran provinces in order to development disparities reduction among them. I...

Damage identification of structures using second-order approximation of Neumann series expansion

In this paper, a novel approach proposed for structural damage detection from limited number of sensors using extreme learning machine (ELM). As the number of sensors used to measure modal data is normally limited and usually are less than the number of DOFs in the finite element model, the model reduction approach should be used to match with incomplete measured mode shapes. The second-order a...
