متن کاملNONLINEAR FRAME ANALYSIS BY MINIMIZATION TECHNIQUE
By minimizing the total potential energy function and deploying the virtual work principle, a higher-order stiffness matrix is achieved. This new tangent stiffness matrix is used to solve the frame with geometric nonlinear behavior. Since authors’ formulation takes into account the higher-order terms of the strain vector, the convergence speed of the solution process will increase. In fac...
متن کاملA Hybrid FDTD–Wavelet-Galerkin Technique for the Numerical Analysis of Field Singularities Inside Waveguides
A novel hybrid Finite Difference Time Domain–Wavelet-Galerkin (FDTD–WG) technique is presented for the accurate representation of electromagnetic field solution in regions of fast field transitions. Its fundamental concept lies on the combination of the robust FDTD method with the Wavelet–Galerkin formulation, which in its turn can efficiently treat highly varying phenomena. The computational d...
متن کاملA meshless technique for nonlinear Volterra-Fredholm integral equations via hybrid of radial basis functions
In this paper, an effective technique is proposed to determine thenumerical solution of nonlinear Volterra-Fredholm integralequations (VFIEs) which is based on interpolation by the hybrid ofradial basis functions (RBFs) including both inverse multiquadrics(IMQs), hyperbolic secant (Sechs) and strictly positive definitefunctions. Zeros of the shifted Legendre polynomial are used asthe collocatio...
متن کاملA Hybrid Nonlinear-Discriminant Analysis Feature Projection Technique
Feature set dimensionality reduction via Discriminant Analysis (DA) is one of the most sought after approaches in many applications. In this paper, a novel nonlinear DA technique is presented based on a hybrid of Artificial Neural Networks (ANN) and the Uncorrelated Linear Discriminant Analysis (ULDA). Although dimensionality reduction via ULDA can present a set of statistically uncorrelated fe...
