Coplanar Constant Mean Curvature Surfaces, Karsten Grosse-Brauckmann, Robert Kusner, John M. Sullivan
Coplanar Constant Mean Curvature Surfaces, Karsten Grosse-Brauckmann, Robert Kusner, John M. Sullivan
Robert Kusner
We consider constant mean curvature surfaces with finite topology, properly embedded in three-space in the sense of Alexandrov. Such surfaces with three ends and genus zero were constructed and completely classified by the authors. Here we extend the arguments to the case of an arbitrary number of ends, under the assumption that the asymptotic axes of the ends lie in a common plane: we construct and classify the entire family of these genus-zero, coplanar constant mean curvature surfaces.

Fixed Points Of Abelian Actions On S2, John Franks, Michael Handel, Kamlesh Parwani
Kamlesh Parwani
We prove that if $F$ is a finitely generated abelian group of orientation preserving $C^1$ diffeomorphisms of $R^2$ which leaves invariant a compact set then there is a common fixed point for all elements of $F.$ We also show that if $F$ is any abelian subgroup of orientation preserving $C^1$ diffeomorphisms of $S^2$ then there is a common fixed point for all elements of a subgroup of $F$ with index at most two.

The Apostle Table - Part Iii - Incompetent Endogenous Response Intransitivity, David Randall Jenkins
David Randall Jenkins
The Apostle Table illustrates a New Testament encryption scheme revealed in the Book of Matthew. Specifically, the list of the twelve apostles in Matthew, 10:1-4, points to the Matthew, Chapters 8 and 9, disciple characterizations. The disciples metaphorically characterize the social choice theory aspect of the scripture writers' (ordered relations theory: social choice theory: welfare model) regression. The paper is written in two parts: I. The Exogenous Pressures; and, II. The Endogenous Response. Interestingly, the paper explains why the crucified Jesus could not get off the cross.

We prove that if $\F$ is an abelian group of $C^1$ diffeomorphisms isotopic to the identity of a closed surface $S$ of genus at least two then there is a common fixed point for all elements of $\F.$

We have measured the transverse asymmetry AT' in the quasielastic 3He(e,e') process with high precision at Q2 values from 0.1 to 0.6 (GeV/c)2. The neutron magnetic form factor GnM was extracted at Q2 values of 0.1 and 0.2(GeV/c)2 using a nonrelativistic Faddeev calculation which includes both final-state interactions (FSI) and meson-exchange currents (MEC). Theoretical uncertainties due to the FSI and MEC effects were constrained with a precision measurement of the spin-dependent asymmetry in the threshold region of 3He(e,e'). We also extracted the neutron magnetic form factor …

Application Of Ansys In Seismic Response Analysis Of Constructing Of High Buildings, Yang Xiaojun
Xiao-Jun Yang
The dynamic feature of high buildings is discussed in the present study with the application of ANSYS,the large finite element analysis software,aimed at the analysis of dynamic response of high buildings.Based on the case of a 15一story-building,a model of beam and shell 3-D finite element structure is built and the frequency of structure and the mode of vibration are computed in the study;furthermore,the structural dynamic response is discussed under different seismic waves with the use of the history analysis method.The results show that the more intense the seismic wave is,the bigger is the dynamic response of the buildings.The information can …

Graphics With Pgf And Tikz, Andrew Mertz, William Slough
Graphics With Pgf And Tikz, Andrew Mertz, William Slough
Andrew Mertz
Beautiful and expressive documents often require beautiful and expressive graphics. PGF and its front-end TikZ walk a fine line between power, portability and usability, giving a TEX-like approach to graphics. While PGF and TikZ are extensively documented, first-time users may prefer learning about these packages using a collection of graduated examples. The examples presented here cover a wide spectrum of use and provide a starting point for exploration.

Programming With Perltex, Andrew Mertz, William Slough
Programming With Perltex, Andrew Mertz, William Slough
Andrew Mertz
PerlTEX couples two well-known worlds—the Perl programming language and the LATEX typesetting system. The resulting system provides users with a way to augment LATEX macros with Perl code, thereby adding programming capabilities to LATEX that would otherwise be difficult to express. In this paper, we illus- trate the use of PerlTEX with a variety of examples and explain the associated Perl code. Although Perl may perhaps be best known for its string manipula- tion capabilities, we demonstrate how PerlTEX indirectly provides support for “programming” graphics through the use of additional packages such as TikZ.
A "Sound" Approach To Fourier Transforms: Using Music To Teach Trigonometry, Bruce Kessler
A "Sound" Approach To Fourier Transforms: Using Music To Teach Trigonometry, Bruce Kessler
Bruce Kessler
If a large number of educated people were asked, ``What was your most exciting class?'', odds are that very few of them would answer ``Trigonometry.'' The subject is generally presented in a less-than-exciting fashion, with the repeated caveat that ``you'll need this when you take calculus,'' or ``this has lots of applications'' without ever really seeing many of them. This manuscript addresses how the author is trying to change this tradition by exposing casual students from kindergarten to college to Joseph Fourier's secret, that nearly any function can be built out of sine and cosine curves. And music serves as …

Closure Under Transfinite Extensions, Edgar E. Enochs, Alina Iacob, Overtoun Jenda
Alina Iacob
The closure under extensions of a class of objects in an abelian category is often an important property of that class. Recently the closure of such classes under transfinite extensions (both direct and inverse) has begun to play an important role in several areas of mathematics, for example in Quillen’s theory of model categories and in the theory of cotorsion pairs. In this paper we prove that several important classes are closed under transfinite extensions

Computing And Introductory Statistics, Daniel Kaplan
Computing And Introductory Statistics, Daniel Kaplan
Daniel T. Kaplan
Much of the computing that students do in introductory statistics courses is based on techniques that were developed before computing became inexpensive and ubiquitous. Now that computing is readily available to all students, instructors can change the way we teach statistical concepts. This article describes computational ideas that can support teaching George Cobb's Three Rs of statistical inference: Randomize, Repeat, Reject.
Symbolization Of Generating Functions; An Application Of The Mullin–Rota Theory Of Binomial Enumeration, Tian-Xiao He, Peter J.S. S, Leetsch C. Hsu
Symbolization Of Generating Functions; An Application Of The Mullin–Rota Theory Of Binomial Enumeration, Tian-Xiao He, Peter J.S. S, Leetsch C. Hsu
Tian-Xiao He
We have found that there are more than a dozen classical generating functions that could be suitably symbolized to yield various symbolic sum formulas by employing the Mullin–Rota theory of binomial enumeration. Various special formulas and identities involving well-known number sequences or polynomial sequences are presented as illustrative examples. The convergence of the symbolic summations is discussed.
Fourier Transform Of Bernstein–Bézier Polynomials, Tian-Xiao He, Charles K. Chui, Qingtang Jiang
Fourier Transform Of Bernstein–Bézier Polynomials, Tian-Xiao He, Charles K. Chui, Qingtang Jiang
Tian-Xiao He
Explicit formulae, in terms of Bernstein–Bézier coefficients, of the Fourier transform of bivariate polynomials on a triangle and univariate polynomials on an interval are derived in this paper. Examples are given and discussed to illustrate the general theory. Finally, this consideration is related to the study of refinement masks of spline function vectors.
Two Number-Theoretic Problems That Illustrate The Power And Limitations Of Randomness, Andrew Shallue
Two Number-Theoretic Problems That Illustrate The Power And Limitations Of Randomness, Andrew Shallue
Andrew Shallue
This thesis contains work on two problems in algorithmic number theory. The first problem is to give an algorithm that constructs a rational point on an elliptic curve over a finite field. A fast and easy randomized algorithm has existed for some time. We prove that in the case where the finite field has characteristic 2, there is a deterministic algorithm with the same asymptotic running time as the existing randomized algorithm.

Tian-Xiao He
We define the Sheffer group of all Sheffer-type polynomials and prove the isomorphism between the Sheffer group and the Riordan group. An equivalence of the Riordan array pair and generalized Stirling number pair is also presented. Finally, we discuss a higher dimensional extension of Riordan array pairs.
