A Geometric Approach to Least Squares
… of this thesis is to view linear regression in a geometric light. Lines in the plane can be identified with points on the cylinder, and fitting a line to a data set can be defined by mapping from that cylinder to R. The best-fit line would then be the minimum point for that function. The two new …

A Geometric Approach to Biomedical Time Series Analysis
<p>Biomedical time series are non-invasive windows through which we may observe human systems. Although a vast amount of information is hidden in the medical field's growing collection of long-term, high-resolution, and multi-modal biomedical time series, effective algorithms for extracting that …

Cellular-Assisted Vehicular Communications: A Stochastic Geometric Approach
… contribution of this thesis is the stochastic geometric analysis of a maximum power-based cellular-assisted VANET scheme, in which a vehicle receives information from either the nearest vehicle or the nearest cellular base station, based on the received power. We have characterized the network …

Rule Extraction from Support Vector Machines: A Geometric Approach
… models. In this thesis, an algorithm called Geometric and Oracle-Based Support Vector Machines Rule Extraction (GOSE) has been proposed to overcome the limitations of other rule-extraction methods by extracting comprehensible models from Support Vector Machines (SVM). This algorithm views the …

Chained Aggregation and Control System Design: A Geometric Approach
This thesis is an indepth study of the Generalized Hessenberg Representation (GHR) of a linear time-invariant control system. It is shown that the GHR explicitly exhibits a sequence of observability subspaces, { (,i)}. By studying these subspaces in this specific basis, a number of results follow.

A Geometric Approach for Generating Feasible Configurations of Robotic Manipulators
… solution space. This property has motivated approaches that leverage non-Euclidean geometries to replace conventional constraints and optimization criteria, thereby overcoming computational bottlenecks and common failure modes. The contributions presented in this thesis propose three such …

Exploration of a geometric approach for estimating snow surface roughness
… of surface roughness elements. Two different geometric evaluations, the Lettau and Counihan methods, were used for the estimation of Z0. The estimates based on surface geometry were evaluated and compared to anemometric Z0 values calculated from field observations of wind turbulence across the …

A Geometric Approach for Deciphering Protein Structure from Cryo-EM Volumes
… In this dissertation, we present a suite of geometric algorithms to address several aspects of protein modeling using cryo-EM density maps. Specifically, we develop novel methods to capture the shape of density volumes as geometric skeletons. We then use these skeletons to find secondary …

A geometric approach to determination of satellite ephemeris over a limited area
… examined for their potential, application in a geometric approach to determination of satellite ephemeri. The approach differs from the normal (dynamic) approach in that each satellite position is treated as an independent state variable or benchmark. Programs have been developed that simulate …

Estimating the Intrinsic Dimension of High-Dimensional Data Sets: A Multiscale, Geometric Approach
<p>This work deals with the problem of estimating the intrinsic dimension of noisy, high-dimensional point clouds. A general class of sets which are locally well-approximated by <italic>k</italic> dimensional planes but which are embedded in a <italic>D</italic>>><italic>k</italic> dimensional …

Designing Adaptive Ansätze in Quantum Simulation and Geometric Entangling Gates
… is about designing fast entangling gates with a geometric approach. We show that the geometric approach can improve the existing numerical methods by locating the good initial guesses.

Eigenanalysis solution for quasi birth and death process
… solution to such models based on Neuts's matrix geometric approach have appeared frequently in the literature. A major problem in using the matrix geometric approach is the computation of the rate matrix, which requires the solution of a matrix polynomial. In particular, computational times …

A Study of Benefits Gained from Industrial Mathematics by Students in the Inglewood Unified School District, Inglewood, California
… Unified School District, something of a geometric approach has been used. Starting from several varied points, an attempt has been made to plot a single “unknown point,” the actual value of Industrial Mathematics.

On a pseudodifferential calculus with modest boundary decay condition
… Instead of functional analytic methods, a geometric approach is invoked in pursuing the Fredholm criterion. As an application, a detailed proof of the Atiyah-Patodi-Singer index theorem, including a review of Dirac operators of product type and construction of the heat kernel, is …

Geometric Fuzzy Logic Systems
… in this research. This thesis presents the novel approach ofdefining fuzzy sets as geometric objects - geometric fuzzy sets. The logical operations for geometric fuzzy sets are defined as geometric manipulations of these sets. This novel geometric approach is applied to type-I, type-2 interval and …
