A Burr type X chainoflinks model
(Texas Tech University, 200105)In this thesis, the study of the Burr type X (often abbreviated BurrX) family of distributions applied to the chainoflinks model is considered. The Burr type X distribution was introduced by I. W. Burr in 1942. At that ... 
A college approach to fractals in middle school
(200508)The algebra and geometry of complex numbers were presented to eighth and ninth grade mathematics classes. The purpose of the presentations was to determine if this college level mathematics would have an influence on the ... 
A comparison of mean and mode for bayesian problem
(201412)Simulation is wildly used in many academic research areas. This thesis will set up a model to find out the true price in a new market from an urn problem. Black and white balls are drawn from the urn with replacement. From ... 
A computational model for flexible wing based micro air vehicles
(200608)Due to the complexities of the wing structure of a micro air vehicle, MAV, a computational model of the aircraft wing requires a combination of many structural elements. The wing typically consists of a flexible membrane ... 
A computational threefield methodology for nonconforming finite elements over partitioned domains
(200505)In this thesis, we describe a computational methodology to couple physical processes defined over independent subdomains, that are partitions of a global domain in threedimensions. The methodology presented helps to ... 
A dynamical system study of the HodgkinHuxley Model of nerve membrane
(201208)Equations of the Hodgkin and Huxley model of action potentials in squid giant axons have been studied and described in this thesis. Explanation of the development of the space clamp model that won its authors the Nobel ... 
A finite difference method for a Stefan problem
(Texas Tech University, 197805)The purpose of this paper is to approximate the solution of a Stefan problem using an implicit finite difference analog for the heat equation and an explicit finite difference analog for the differential equation describing ... 
A four moment solution to the BehrensFisher problem
(Texas Tech University, 198112)Not available 
A generalized invariant imbedding for wave propagation
(Texas Tech University, 198305)Not available 
A generalized linear complexity
(Texas Tech University, 199205)Certain cryptographic applications require pseudorandom sequences which are "unpredictable," in the sense that recovering the sequence from a short captured segment is computationally infeasible. Such sequences are said ... 
A graduate pedagogy course for mathematics teaching assistants
(Texas Tech University, 200505)We will describe a three semesterhour graduate level mathematics course which focuses on issues related to the teaching of mathematics at the college level and is taken by all new graduate students entering our program ...

A group of families of polynomials with imaginary zeros
(Texas Tech University, 193808)Not available 
A jumpdiffusion stochastic differential equation eodel for insurance in risksharing villages
(201312)This thesis presents the idea of insurance in risksharing villages in less developed countries. In less developed world people deal with different kinds of risks which yield high variation in household income. These risks ... 
A mathematical model of human saccadic eye movement
(Texas Tech University, 199805)A homeomorphic model of the eye movement plant is developed and used to simulate human saccadic eye movement. The Hillbased model incorporates nonlinear musculotendon dynamics. The effects of particular system parameters ... 
A method for truncation of a sequential test assuming an underlying exponential density function
(Texas Tech University, 196706)Not available 
A method of classification by geometric characteristics of certain equations in N variables through the use of extended analytic geometry
(Texas Tech University, 196306)Not available 
A modified simple shooting method for solving twopoint boundary value problems
(Texas Tech University, 200305)In physics and engineering, one often encounters what is called a twopoint boundary value problem (TPBVP). Several methods exist, for solving these problems. Shooting methods, such as the Simple Shooting Method (SSM) and ... 
A new approach of geneticbased EM algorithm for mixture models
(201105)Finite mixture models have been receiving an important attention over the years in practical and theoretical point of view, but it is still challenging task to estimate a reasonable estimator based on the maximum likelihood ...
