Creative Matrix
… together, has become what I call a creative matrix. I see my images as choreographed compositions using a mixed media approach. The open-ended interpretation of my art have expanded the never ending possibilities of creation.

A Reconfigurable FPGA Overlay Architecture for Matrix-Matrix Multiplication
… attempts to develop hardware accelerators for matrix-matrix multiplication. Both application-specific integrated circuits (ASICs), and field-programmable arrays (FPGAs) are used for this purpose. However, a trade-off between the two platforms is that ASICs provide little flexibility after they …

Toroidal Matrix Links: Local Matrix Homotopies and Soft Tori
… we solve some local connectivity problems in matrix representations of the form C(T^N) -> M_n and C(T^N) -> M_n <- C([-1, 1]^N) using the so called toroidal matrix links, which can be interpreted as normal contractive matrix analogies of free homotopies in algebraic topology. In order to deal …

The computation of matrix functions in particular, the matrix exponential
Matrix functions in general are an interesting area in matrix analysis and are used in many areas of linear algebra and arise in numerous applications in science and engineering. We consider how to define matrix functions and how to compute matrix functions. To be concrete, we pay particular …

Altering the fiber-matrix interphase in semicrystalline polymer matrix composites
When many semicrystalline polymers are used as matrix materials in composites, a morphology known as the transcrystalline region is formed on the surface of the reinforcing material. This region introduces a new crystalline structure to the system that is different from that of the bulk matrix …

Matrix Organization Theory
Matrix organization management is a rather new concept of organization and management. Variations of traditional and project organizations have been utilized for centuries. However, the organization structure denoted by the term "matrix” has been recognized and documented only over the past two …

Sparse matrix spaces
… or an arbitrary real number. We call them sparse matrix spaces, abbreviated SMS, and examine under what conditions they contain matrices for which all eigenvalues have strictly negative real parts. We call an SMS with this property stable. We start by reviewing the necessary background from …

Orthogonal matrix polynomials and differential, difference and q-difference matrix operators
… of result that are framed in the theory of Matrix Orthogonal Polynomials, a branch of the very celebrated subject of Orthogonal Polynomials. In particular we study families of matrix valued orthogonal polynomials satisfying differential, difference or q-difference equations. The search for …

Transverse fracture and fiber/matrix interface characteristics of hybrid ceramic matrix composites
<p>"Ceramic Matrix Composites (CMCs) represent an attractive class of engineering materials for use in high temperature, high wear and corrosive environments. Much effort has been made to ascertain and improve the strength and fracture characteristics of these materials. Approaches that have …

Solutions of Matrix Equations
… matrices A and B can make many different matrix equations, e.g., <em>AB</em> = <em>BA</em>, <em>AB</em> = <em>AA</em>, <em>ABA</em> = <em>BAB</em>, and <em>AAB</em> = <em>BAA</em>. It is not always easy to describe solutions to these matrix equations. This thesis considers the problem of …

Preconditioning For Matrix Computation
… to solve. The two central subjects of numerical matrix computations are LIN-SOLVE, that is, the solution of linear systems of equations and EIGEN-SOLVE, that is, the approximation of the eigenvalues and eigenvectors of a matrix. We focus on the former subject of LIN-SOLVE and show an application …

Low rank matrix completion
We consider the problem of recovering a low rank matrix given a sampling of its entries. Such problems are of considerable interest in a diverse set of fields including control, system identification, statistics and signal processing. Although the general low rank matrix completion problem is …

Algorithms for matrix completion
We consider collaborative filtering methods for matrix completion. A typical approach is to find a low rank matrix that matches the observed ratings. However, the corresponding problem has local optima. In this thesis, we study two approaches to remedy this issue: reference vector method and trace …

Clustering via matrix exponentiation
Given a set of n points with a matrix of pairwise similarity measures, one would like to partition the points into clusters so that similar points are together and different ones apart. We present an algorithm requiring only matrix exponentiation that performs well in practice and bears an elegant …
