Locally Topological Groupoids, Osman Mucuk

Turkish Journal of Mathematics

The notion of Iocally topological groupoid was introduced by Aof and Brown in [2]. On the other hand in [6] by Mackenzie a topological groupoid MG, called monodromy groupoid, is constructed. In this paper we prove that this groupoid MG gives a Iocally topological groupoid.

The Spectra And Fine Spectra For P-Cesáro Operators, Cafer Coşkun

Turkish Journal of Mathematics

In [6], Rhaly computed the spectrum of p-Cesaro operator on the Hilbert space l_2 = {x = (x_k): \Sigma_k IX_kl^2 < infinite}. In the present paper, we study the spectrum and fine spectrum for p-Cesáro operators acting on C_o, the space of null sequences.

Painlevé Analysis And Infinite Lie Symmetries Of The Complex Modified Korteweg-De Vries-Ii Equation, Abulgassim Ali Muhammad, Mehmet Can

Turkish Journal of Mathematics

The Painleve analysis developed by Weiss et al. [9] for nonlinear partial differential equations is applied to the CMKdV-II equation. It has been shown that this equation passes the Painleve test. By specializing the arbitrary functions that appear in the phi series expansions found in the test, one obtains a system of partial differential equations for the formally arbitrary data. For specific systems, and conjectured in general, these equations are integrable. The form of the resulting reduction enables the identification of integrable reductions of the original systems. Assuming u_i = \upsilon_i = 0, i >= 2 we obtain conditions to …

On The Solution Of The E.P.D. Equation Using Finite Integral Transformations, Neşe Dernek

Turkish Journal of Mathematics

In this paper, a solution is given for the following initial boundary value problem: \Delta=u_{tt}+k/t+u_t+g(x, t) (t>0) u(0, t)=u(a, t)=0 u(x, 0)=f(x), u_t(x, 0)=0 where x, a \epsilon R^n, t is the time variable, k < 1, k ? -1, -2, -3, . . . is a real parameter, \Delta is the n dimensional Laplace operator, f and g real analytic functions. The equation in this problem is known as the nonhomogeneous Euler-Poisson-Darboux (E.P.D.) Equation. The solution is obtained using finite integral transformation technique and is the sum of two uniformly and absolutely convergent power series.

Locally Nilpotent P-Groups Whose Proper Subgroups Are Nc-Groups, A.O. Asar, A. Yalincaklioğlu

Turkish Journal of Mathematics

Let G be a locally nilpotent p-group in which every proper subgroup is an NC-group. It is shown that G is itself an NC-group if either (i) the normal closure of every finite subgroup of G is a Chernikov extension of a CC-group or (ii) every proper normal subgroup of G is the union of an ascending chain of normal CCsubgroups.

Set Theoretic Real Analysis, Krzysztof Ciesielski

Faculty & Staff Scholarship

This article is a survey of the recent results that concern real functions (from Rⁿ into R) and whose solutions or statements involve the use of set theory. The choice of the topics follows the author's personal interest in the subject, and there are probably some important results in this area that did not make to this survey. Most of the results presented here are left without the proofs.

Darboux Like Functions That Are Characterizable By Images, Preimages And Associated Sets, Krzysztof Ciesielski

Faculty & Staff Scholarship

For arbitrary families A and B of subsets of R let C(A,B)= {f| f: R-->R and the image f[A] is in B for every A in A} and C^-1 (A,B)= {f| f: R-->R and the inverse image f^-1(B) is in A for every B in B}. A family F of real functions is characterizable by images (preimages) of sets if F=C(A,B) (F=C^-1(A,B), respectively) for some families A and B. …

Surface Morphology Of Gan Films Determined From Quantitative X-Ray Reflectivity, D Lederman, Zhonghai Yu, T H. Myers, Michelle Richards-Babb

Faculty & Staff Scholarship

The surface of two GaN films grown under Ga-rich conditions by molecular beam epitaxywas characterized using x-ray reflectivity, assuming a self-affine/fractal surface morphology. The surface height fluctuations were similar for both samples at the largest lateral length scales at which the fractal description is valid, although this lateral length was significantly greater and the “jaggedness” significantly smaller for the sample grown under higher Ga flux. Previous atomic force microscopy images revealed a higher density of large features on the surface for the sample grown under lower Ga flux. The lateral size of the features are dominated by a convolution of …

Particle Modeling Of Liquid Drop Formation On A Solid Surface In 3-D, Mark Korlie

Department of Mathematics Faculty Scholarship and Creative Works

Using a molecular aggregate approach and classical Newtonian dynamics, we show how to simulate a liquid drop formation on a horizontal solid surface in three-dimensional space. We use sets of quasi-molecular particles which interact in accordance with classical molecular-type formulas. For application, the liquid is taken to be water while the solid surface is taken to be graphite. The resulting dynamical equations for the particles are large systems of second-order, nonlinear, ordinary differential equations which must be solved by a numerical method. Computer simulations of the results and related contact angle calculations are presented and discussed. The results are in …

Particle Simulation Of Carbon Dioxide Bubbles In Water, Mark Korlie, D. Greenspan

Department of Mathematics Faculty Scholarship and Creative Works

Using a molecular aggregate approach and classical molecular dynamics type formulas, a method that can be used to simulate the motion of fluid drops within fluids is described through a detailed study of a prototype problem, the motion of carbon dioxide bubbles in water. The resulting equations are solved numerically. The rise of the bubbles and the motion of the water near the bubbles are described.

Parallel Algorithms For Single-Layer Channel Routing, Ronald I. Greenberg, Shih-Chuan Hung, Jau-Der Shih

Computer Science: Faculty Publications and Other Works

We provide efficient parallel algorithms for the minimum separation, offset range, and optimal offset problems for single-layer channel routing. We consider all the variations of these problems that are known to have linear- time sequential solutions rather than limiting attention to the "river-routing" context, where single-sided connections are disallowed. For the minimum separation problem, we obtain O(lgN) time on a CREW PRAM or O(lgN / lglgN) time on a (common) CRCW PRAM, both with optimal work (processor- time product) of O(N), where N is the number of terminals. For the offset range problem, we obtain the same time and processor …

Reflections On The Gao Report On The Nuclear Triad, David W. Hafemeister

Physics

Senate Hearings on the GAO report on the nuclear triad and on the START treaty showed that vulnerabilities of the U.S. triad were vastly over‐stated, that the performance of new projected strategic systems was over‐estimated, and that the performance of existing U.S. strategic systems was under‐estimated. These exaggerations enhanced the psychological (Freud) aspects of the Cold War and compromised logic (Newton).

With the end of the Cold War it is imperative that we re‐examine the basic premises that guided the choices of the strategic nuclear systems. The initial bottom line is that these systems were successful in that they did …

Three-Dimensional Direct Simulation Monte Carlo Method For Slider Air Bearings, Alejandro Garcia, W. Huang, D. B. Bogy

Faculty Publications

The direct simulation Monte Carlo (DSMC) method is used to solve the three-dimensional nano-scale gas film lubrication problem between a gas bearing slider and a rotating disk, and this solution is compared to the numerical solution of the compressible Reynolds equations with the slip flow correction based on the linearized Boltzmann equation as presented by Fukui and Kaneko [molecular gas film lubrication (MGL) method] [ASME J. Tribol. 110, 253 (1988)]. In the DSMC method, hundreds of thousands of simulated particles are used and their three velocity components and three spatial coordinates are calculated and recorded by using a hard-sphere collision …

Semantic Analysis Of The Postscript Page Description Language, Ben Knuth

Honors Theses, 1963-2015

The Postscript page description language is a functional programming language. Central to the effective use of the language are the functional properties of delayed evaluation and referential transparency. Postscript performs all of its operations via distinct, multiple stacks which stores function binding lists, function parameters, and function code. By way of these stacks, Postscript creates dynamic computational states which leads identical expressions to evaluate to different results. This hints towards the polymorphic quality of an object-oriented language, even though it contradicts the functional precept of manifest interfaces thereby introducing a nonorthogonality. One other streak of object-orientation that shows up in …

Where The Guesswork Ends And The Accrual Begins: Environmental Remediation Liabilities And Their Effects On The Managerial Decision-Making Process, Corie Sue Dumdie

Honors Theses, 1963-2015

Environmental remediation is not new, but accounting for the costs of such a process is. In 1996, the first authoritative literature on accounting for the costs of cleaning up environmental degradation were established, and they gave insight into the accounting treatment for environmental remediation liabilities (ERLs). The aim of the thesis is to explain the new accrual methods for ERLs and show their importance as they have influenced many managerial philosophies. The thesis also examines some of the weaknesses of ERLs and illustrates possible changes for the future. The most important aspect of ERLs is that they have helped management …

A Comparison Of The Kinetics Of Fatty-Acid Metabolism In Smokers And Nonsmokers, Patricia A. Valusek

Honors Theses, 1963-2015

For many years, the United States government has required labels on all cigarette packages warning against the many ill effects associated with smoking. One of the major factors contributing to the unhealthy aspects of smoking is its profound impact on nutrient levels within the body. Free radicals found in both the gas and tar phases of cigarette smoke may pose a significant threat to the fatty-acid levels in the body. One method of assessing this threat is to examine the fatty-acid synthesis rates of smokers and nonsmokers. An assumption was made that a destruction of fatty-acids will be displayed as …
