GPU-accelerated Linear Solvers for High-order Finite Element Methods in Poisson Problems
… improving the convergence and efficiency of the preconditioned conjugate gradient (PCG) algorithm for high-order finite element methods on Graphics Processing Units (GPUs). The conjugate gradient algorithm iteratively refines an initial approximate solution until a specified stopping criterion is …

Integrated structural analysis and design using 3-D finite elements
… noded elements. An element by element (EBE) preconditioned conjugate gradient (PCG) method is used for the structural analysis, because this method is well suited for poorly banded three dimensional problems. The plates were optimized so as to minimize the stress concentration near the hole …

Efficient tranceiver [sic] techniques for interference and fading mitigation in wireless communication systems
… contribution for this part is the Stochastic Gradient Pursuit algorithm for sparse adaptive equalization. An alternative approach to combat ISI is based on the orthogonal frequency division multiplexing (OFDM) system. In this system, the entire channel is divided into many narrow subchannels, …

Multi-scale problems: an improved non-intrusive algorithm that enhances FEA platforms with the generalized finite element method; An improved preconditioned conjugate gradient solver for hierarchical generalized finite element systems of equations
… possible. An iterative solver called the preconditioned conjugate gradient method is investigated within this context, and a preconditioner is proposed for the method. This thesis shows that its proposed iterative solver is faster than previous iterative solvers. The proposed iterative …
