Using Domination to Analyze RNA Structures.
… Recently researchers at the Courant Institute of Mathematical Sciences used graph theory to model RNA molecules and provided a database of trees representing possible secondary RNA structures. In this thesis we use domination parameters to predict which trees are more likely to exist in nature as …

Fourier Analysis of Wave Equations
… of the major influential and useful subjects in Mathematical Sciences. In this thesis, I mainly use Fourier analysis and PDE methods to study the solution to an inhomogeneous wave equation on Euclidean spaces. I obtained the existence, uniqueness, and regularity for the solution. In the classical …

Implementing the NCTM Standards in a Traditional Classroom
… It was concluded by the Conference Board of the Mathematical Sciences, National Advisory Committee on Mathematical Education, that the "new math" was never implemented in the classroom even though it was detailed in various textbooks. Evans (1993) reiterated that the realities of implementation …

Can I Do Math If I Can't Read? - The Relationship Between Reading and Mathematics Standards of Learning Assessments in One High School In Virginia
How well students perform in mathematics and sciences continues to be a measure of a country's worth (Conference Board of the Mathematical Sciences [CBMS], 2012). Nations that want an educated citizenry have consistently studied ways in which to improve performance in mathematics (Claessens and …

Efficient Structure and Motion: Path Planning, Uncertainty and Sparsity
This thesis explores methods for solving the structure-and-motion problem in computer vision, the recovery of three-dimensional data from a series of two-dimensional image projections. The first paper investigates an alternative state space parametrization for use with the Kalman filter approach to …

Efficient Algorithms for Graph-Theoretic and Geometric Problems
This thesis studies several different algorithmic problems in graph theory and in geometry. The applications of the problems studied range from circuit design optimization to fast matrix multiplication. First, we study a graph-theoretical model of the so called ''firefighter problem''. The …

Splitting schemes for nonlinear parabolic problems
This thesis is based on five papers, which all analyse different aspects of splitting schemes when applied to nonlinear parabolic problems. These numerical methods are frequently used when a problem has a natural decomposition into two or more parts, as the computational cost may then be …

Planar Motion and Visual Odometry: Pose Estimation from Homographies
This thesis concerns ego-motion and pose estimation of a single camera under the assumptions of planar motion and constant internal camera parameters. Planar motion is common for cameras mounted onto mobile robots, particularly in indoor scenarios, as they remain at a constant height above the …

Sparse Modeling of Grouped Line Spectra
This licentiate thesis focuses on clustered parametric models for estimation of line spectra, when the spectral content of a signal source is assumed to exhibit some form of grouping. Different from previous parametric approaches, which generally require explicit knowledge of the model orders, this …

Machine Vision for Road Pavement Applications Bitumen Coverage and Grain Size Estimation
In this thesis some research questions regarding durability and quality of roads has been investigated. The questions are analyzed from an image analysis point of view and aims to be a complement to existing methods for analyzing asphalt. One important factor for the durability of the asphalt layer …

On Vertex Operator Algebras of Affine Type at Admissible Levels
The main purpose of this thesis is the study of the structure and representation theory of simple vertex operator algebras (VOAs) of affine type at admissible levels. To do this, it is crucial to obtain knowledge of the singular vectors which generate the maximal submodules, with respect to which …

On the existence of complex-valued harmonic morphisms
This thesis consists of 4 papers, their content is described below: Paper I. We present a new method for manufacturing complex-valued harmonic morphisms from a wide class of Riemannian Lie groups. This yields new solutions from an important family of homogeneous Hadamard manifolds. We also give a …
