Polynomial methods in statistical inference: Theory and practice
… of samples. In this dissertation, we apply the polynomial methods to several statistical questions with rich history and wide applications. The goal is to understand the fundamental limits of the problems in the large domain regime, and to design sample optimal and time efficient algorithms with …

Control strategies for functional electrical stimulation induced cycling
… Thereafter controllers are designed, via polynomial methods. The results show that the controllers are robust during cadence tracking, power tracking and for disturbance rejection. The controllers can be accurately applied to exercise testing protocols. The concept of VO2 control is …

Thomas Fermi model for mesons and new noise subtraction techniques in lattice QCD.
… calculate these diagrams we use stochastic noise methods, which employ a randomly generated set of noise vectors to project out physical signals. This is done with linear equation solvers like GMRES-DR (Generalized Minimum RESidual algorithm-Deated and Restarted) for the first noise, and …

Pseudospectral methods in quantum and statistical mechanics
… pseudospectral method is a family of numerical methods for the solution of differential equations based on the expansion of basis functions defined on a set of grid points. In this thesis, the relationship between the distribution of grid points and the accuracy and convergence of the solution …

Polynomial-Based Methods for Time-Integration
… framework that is based on interpolating polynomials, and the second extends exponential integration to the spectral deferred correction framework. Both parts discuss time integration methods that can be derived without solving nonlinear order conditions. In part I, we introduce a …

H-Infinity Norm Calculation via a State Space Formulation
… use operator theory, J-spectral factorization or polynomial methods while in the state space approach one uses ideas similar to LQ theory and differential games. One of the key computational issues in the design of H-infty optimal controllers is the determination of the optimal H-infty norm. That …

Characteristic polynomials of random matrices and their role in an effective theory of strong interactions
… is to investigate the impact of characteristic polynomials on the spectral eigenvalue statistics of random matrix models, with applications in effective field theory models of Quantum chromodynamics (QCD). The symmetries of the field theory lead to random matrix ensembles named chiral Gaussian …
