Jesus, Plato, Math And Theology: What Is Truth?, Paul Moffett Jun 2005

Jesus, Plato, Math And Theology: What Is Truth?, Paul Moffett

ACMS Conference Proceedings 2005

Mathematical ontology is relevant to Christians because so much of Christian theology has been historically shaped by Platonic mathematics and the ontology that goes with it. The various contributors to Mathematics in a Postmodern Age, edited by Howell and Bradley, seem to assume that Christians are necessarily realists in ontology, and they are not alone. But what is the cause of this Christian connection with mathematical realism in ontology? How much has our idea of God been shaped by Plato and his mathematics?


Blaise Pascal - Mathematician, Mystic, Disciple, Tim Rogalsky Jun 2005

Blaise Pascal - Mathematician, Mystic, Disciple, Tim Rogalsky

ACMS Conference Proceedings 2005

This is the story of a multi-faceted Christian mathematician. Instrumental in the development of calculus, probability theory, and computing machines, Pascal (1623-1662) was a man equally enamoured with mind and spirit. His conversion experience was marked by both rational decision and mystical vision. He is perhaps best known for "Pascal's wager," which simplistic "fire insurance" version of Christianity, demanding little from the convert. However, a more careful reading of his work and his life reveals that Pascal knew much about discipleship and its cost.


Call For A Non-Euclidean, Post-Cantorian Theology, Saburo Matsumoto Jun 2005

Call For A Non-Euclidean, Post-Cantorian Theology, Saburo Matsumoto

ACMS Conference Proceedings 2005

In this paper I propose a new approach to theology, which I refer to as a "non-Euclidean, post-Cantorian" theology. I first review three accomplishments in modern mathematics with lasting philosophical implications: non-Euclidean geometry, set theory, and the Incompleteness Theorems of Gödel. Since all of these are ideas that came after much of traditional theology had already been formed, I challenge that theology be revisited in light of what we can learn from the mathematical struggles that produced these amazing and counter-intuitive truths. I give some concrete examples and propose that such an effort can make non-trivial contribution in theology and …

Filtering The Bible And Filtering Spam, Gene B. Chase Jun 2005

Filtering The Bible And Filtering Spam, Gene B. Chase

ACMS Conference Proceedings 2005

I argue that John Craig (1996?–1731) is the first to do Bayesian statistics. Filtering email spam today using Bayes's analysis of 1763 is a new application of an old theorem. Craig 67 years before Bayes's theorem used subjective probabilities reasoning to argue that Jesus would return in the year 3150, because the Bible would eventually come into disrepute (become spam?) then.


Asserting Cs != Can't Spcialize, Building Community In A Computer Science Program, Kim Kihlstrom Jun 2005

Asserting Cs != Can't Spcialize, Building Community In A Computer Science Program, Kim Kihlstrom

ACMS Conference Proceedings 2005

As humans, we are designed to live in community. "Just as each of us has one body with many members, and these members do not all have the same function, so in Christ we who are many form one body, and each member belongs to all the others" (Romans 12:4-5). We believe it is of critical importance to build community within a computer science program, first of all because it is part of God's calling for us. In addition, building communit allows us to equip students with the interpersonal skills that they need for a productive career, and to attract …

Survival Model And Estimation For Lung Cancer Patients., Xingchen Yuan May 2005

Survival Model And Estimation For Lung Cancer Patients., Xingchen Yuan

Electronic Theses and Dissertations

Lung cancer is the most frequent fatal cancer in the United States. Following the notion in actuarial math analysis, we assume an exponential form for the baseline hazard function and combine Cox proportional hazard regression for the survival study of a group of lung cancer patients. The covariates in the hazard function are estimated by maximum likelihood estimation following the proportional hazards regression analysis. Although the proportional hazards model does not give an explicit baseline hazard function, the baseline hazard function can be estimated by fitting the data with a non-linear least square technique. The survival model is then examined …


Using Domination To Analyze Rna Structures., Travis Reves Coake May 2005

Using Domination To Analyze Rna Structures., Travis Reves Coake

Electronic Theses and Dissertations

Understanding RNA molecules is important to genomics research. 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 RNA structures. This approach appears to have promise in graph theory applications in genomics research.


Fréchet Subdifferential Calculus And Optimality Conditions In Nondifferentiable Programming, Boris S. Mordukhovich, Nguyen Mau Nam, N. D. Yen May 2005

Fréchet Subdifferential Calculus And Optimality Conditions In Nondifferentiable Programming, Boris S. Mordukhovich, Nguyen Mau Nam, N. D. Yen

Mathematics Research Reports

We develop various (exact) calculus rules for Frechet lower and upper subgradients of extended-realvalued functions in general Banach spaces. Then we apply this calculus to derive new necessary optimality conditions for some remarkable classes of problems in constrained optimization including minimization problems for difference-type functions under geometric and operator constraints as well as subdifferential optimality conditions for the so-called weak sharp minima.

Disease Outbreaks In Coupled Populations : An Application To Measles Spread In Cameroon, Kirsten Maggie Viz May 2005

Disease Outbreaks In Coupled Populations : An Application To Measles Spread In Cameroon, Kirsten Maggie Viz

Theses, Dissertations and Culminating Projects

Many childhood diseases can be modeled mathematically using a system of differential equations that group the overall population into compartments. Much research has been done to understand and control the spread of these diseases within a single population and between coupled populations with constant parameters. In this thesis, we are concerned with how a disease is spread through and between coupled populations using models with time-varying parameters and asymmetric coupling.

Measles outbreaks in the West African country of Cameroon present a good example of disease spread with seasonality. By dividing Cameroon into two subpopulations and using parameters that reflect recent …


Lower Bounds For Simplicial Covers And Triangulations Of Cubes, Adam Bliss '03, Francis E. Su Apr 2005

Lower Bounds For Simplicial Covers And Triangulations Of Cubes, Adam Bliss '03, Francis E. Su

All HMC Faculty Publications and Research

We show that the size of a minimal simplicial cover of a polytope P is a lower bound for the size of a minimal triangulation of P, including ones with extra vertices. We then use this fact to study minimal triangulations of cubes, and we improve lower bounds for covers and triangulations in dimensions 4 through at least 12 (and possibly more dimensions as well). Important ingredients are an analysis of the number of exterior faces that a simplex in the cube can have of a specified dimension and volume, and a characterization of corner simplices in terms of their …


A Mathematical Model For Treatment-Resistant Mutations Of Hiv, Helen Moore, Weiqing Gu Apr 2005

A Mathematical Model For Treatment-Resistant Mutations Of Hiv, Helen Moore, Weiqing Gu

All HMC Faculty Publications and Research

In this paper, we propose and analyze a mathematical model, in the form of a system of ordinary differential equations, governing mutated strains of human immunodeficiency virus (HIV) and their interactions with the immune system and treatments. Our model incorporates two types of resistant mutations: strains that are not responsive to protease inhibitors, and strains that are not responsive to reverse transcriptase inhibitors. It also includes strains that do not have either of these two types of resistance (wild-type virus) and strains that have both types. We perform our analysis by changing the system of ordinary differential equations (ODEs) to …


Global Optimality Conditions In Mathematical Programming And Optimal Control, Pariwat Pacheenburawana Apr 2005

Global Optimality Conditions In Mathematical Programming And Optimal Control, Pariwat Pacheenburawana

Dissertations

We derive new first-order necessary and sufficient optimality conditions characterizing global minimizers in mathematical programming and optimal controlproblems. These conditions are based on level sets of an objective functional and they do not assume special structure of a problem (convexity, linearity, etc.). For a mathematical programming problem of minimization of a smooth functional on some compact convex set with equality nonlinear constraints, we derive first-order optimality conditions in the form of a generalized Lagrange multiplier rule. This rule should hold for any point from the level set of the objective functional corresponding to a global minimizer. We demonstrate that these …


Structure Preserving Algorithms For Computing The Symplectic Singular Value Decom Position, Archara Chaiyakarn Apr 2005

Structure Preserving Algorithms For Computing The Symplectic Singular Value Decom Position, Archara Chaiyakarn

Dissertations

In this thesis we develop two types of structure preserving Jacobi algorithms for com puting the symplectic singular value decomposition of real symplectic matrices and complex symplectic matrices. Unlike general purpose algorithms, these algorithms produce symplectic structure in all factors of the singular value decomposition.

Our first algorithm uses the relation between the singular value decomposition and the polar decomposition to reduce the problem of finding the symplectic singular value decomposition to th a t of calculating the structured spectral decomposition of a doubly structured m atrix. A Jacobi-like m ethod is developed to compute this doubly structured spectral decomposition. …


Stratification And Domination In Graphs And Digraphs, Ralucca M. Gera Apr 2005

Stratification And Domination In Graphs And Digraphs, Ralucca M. Gera

Dissertations

In this thesis we combine the idea of stratification with the one of domination in graphs and digraphs, respectively.

A graph is 2-stratified if its vertex set is partitioned into two classes, where the vertices in one class are colored red and those in the other class are colored blue. Let F be a 2-stratified graph rooted at some blue vertex v . An F -coloring of a graph G is a red-blue coloring of the vertices of G in which every blue vertexu belongs to a copy of F rooted at u . The F -domination number γ …


A Sampling And Transformation Approach To Solving Random Differential Equations, Roger A. Erich Mar 2005

A Sampling And Transformation Approach To Solving Random Differential Equations, Roger A. Erich

Theses and Dissertations

This research explores an innovative sampling method used to conduct uncertainty analysis on a system with one random input. Given the distribution of the random input, X, we seek to find the distribution of the output random variable Y. When the functional form of the transformation Y=g(X) is not explicitly known, complicated procedures, such as stochastic projection or Monte Carlo simulation must be employed. The main focus of this research is determining the distribution of the random variable Y=g(X) where g(X) is the solution to an ordinary differential equation and X is a random parameter. Here, y=g(X) is approximated by …
