A Mathematical Curiosity In Estimating The Radius Of The First Ring Electrons Of An Arbitary Atom, Donald Greenspan
A Mathematical Curiosity In Estimating The Radius Of The First Ring Electrons Of An Arbitary Atom, Donald Greenspan
Mathematics Technical Papers
In this note, we explore an elementary method for approximating the radii and speeds of first ring electrons in atoms. The approach uses only a single algebraic equation with parameters. Any particular atom under study defines all the parameters. A simple hand calculator technique always applies for solving any resulting equation. Results are given through calcium and, to three decimal places, are shown, unexpectedly, to be essentially identical to available quantum mechanics calculations.

Mathematics Technical Papers
A new particle-type of modeling is developed for the simulation of phenomena related to the bending of elastic shells. Application is made to the determination of unstable equilibrium modes and to the simulation of snap-through inversion. Computer examples are described and discussed.
A Discrete Model For The Recovery Of Oil From A Reservoir, Cristobal Vargas-Jarillo
A Discrete Model For The Recovery Of Oil From A Reservoir, Cristobal Vargas-Jarillo
Mathematics Technical Papers
In this work we simulate oil recovery by means of a molecular type approach. This means that we consider the solid and liquid materials to be composed of a finite number of particles, which are approximants for molecules. Porous flow is studied qualitatively under the assumption that particles of rock, oil and the flooding flow interact with each other locally by means of a compensating LennardJones type potential and are also under the influence of gravity. Extensive computations are described and discussed in which initial data and parameters are varied. A comparison is made with actual physical experiments.

A Class Of Elliptic Partial Differential Equations With Exponential Nonlineraities, Pierre A. Vuillermot
A Class Of Elliptic Partial Differential Equations With Exponential Nonlineraities, Pierre A. Vuillermot
Mathematics Technical Papers
This is the second of a series of papers devoted to systems of ordinary and partial differential equations with exponential nonlinearities [20], in which we prove the existence of at least a countable infinity of one- parameter families of nontrivial, Hölder continuous solutions for a class of second-order, strongly nonlinear Dirichlet boundary-value problems in two and more dimensions. Let Y be a C(2)-Young function, namely a twice continuously differentiable, even convex lR—valued function on IR such that[see pdf for notation] and[see pdf for notation]. By C(2)-function, we shall mean a function which is twice continuously differentiable everywhere except possibly at …

On A Class Of Strongly Nonlinear Dirichlet Boundary-Value Problems: Beyond Pohozaev's Results, Pierre A. Vuillermot
Mathematics Technical Papers
Let [see pdf for notation] be an open bounded domain with closure [see pdf for notation] and smooth boundary [see pdf for notation]. Consider the class of nonlinear boundary-value problems defined by [see pdf for notation] with [see pdf for notation] regular enough,[see pdf for notation] and where [see pdf for notation] denotes Laplacian. If n = 2, it is known that the boundary-value problem (1.1) possesses nontrivial, classical eigensolutions (with appropriate eigenvalues ^) even if ø grows exponentially fasts if n ≥ 3, it is also known that problem (1.1) has, with ^ starshaped, no nontrivial, classical solutions as …
Homotopy Equivalences On 3-Manifolds, Gerard A. Venema
Homotopy Equivalences On 3-Manifolds, Gerard A. Venema
University Faculty Publications and Creative Works
Suppose M3 is a 3-manifold and f: M3 ⟶ X is a homotopy equivalence onto an ANR X. In this paper the cellularity properties of point preimages under f are studied. It is shown that for every open cover α of X there exists an open cover β of X such that if f is a β-equivalence then each f-1(x) is α-cellular in M3 X R1. In fact, the (open) cellularity occurs in a continuous fashion and so the map f can be approximated by a Euclidean bundle map.
Topoi And Categories Of Fuzzy Sets, Lawrence Stout
Topoi And Categories Of Fuzzy Sets, Lawrence Stout
Lawrence N. Stout
Let H be a completely distributive lattice and hence a Heyting algebra. Goguen's category of fuzzy sets Set(H) Eytan's logos Fuz(H) and the topos of sheaves on H, Sh(H), are interconnected by pairs of adjoint functors between them. Each of the categories has a predicate calculus. These predicate calculi are related through the functors between the categories. Change of base lattice gives rise to several functors which preserve or reflect specific kinds of statements in the predicate calculi. This paper gives details of the categories, the predicate calculi attached to them, the functors between the categories, and the preservation properties …

Maximal functions which measure the smoothness of a function are introduced and studied from the point of view of their relationship to classical smoothness and their use in proving embedding theorems, extension theorems and various results on differentiation. New spaces of functions which generalize Sobolev spaces are introduced.

On Isomorphic Decompositions Of Graphs, Sergio Ruiz
On Isomorphic Decompositions Of Graphs, Sergio Ruiz
Dissertations
A decomposition of a nonempty graph G is a collection of subgraphs G(,1), G(,2), ... , G(,k) of G such that their edge sets form a partition of the edge set of G. If G(,i) is isomorphic to a fixed graph H for each i, then G has an isomorphic decomposition into the graph H or, equivalently, G is H-decomposable. Several topics, each concerning isomorphic decompositions, are investigated in this dissertation.
An historical introduction to the subject of isomorphic decompositions is given in Chapter I. We also present there some new information on finding regular graphs that are H-decomposable for …

The Role Of Nonreal Eigenvalues In The Identification Of Cycles In A Compartmental System, Jerome Eisenfeld, S. M. Grundy, W. F. Beltz
Mathematics Technical Papers
The paper concerns the relationship between the cycles in the graph of a compartmental system and the modes of the impulse response function associated with an input-output experiment. Suppose that there is at least one oscillatory mode, [see pdf for notation]. Let [see pdf for notation] be the slowest mode. The main result is that the system contains a cycle of length three or longer and that the length of the longest cycle is at least [see pdf for notation]. The paper also deals with the problem of estimating cycle length from discrete data.

Existence Of Coupled Quasi-Solutions Of Systems Of Nonlinear Reaction-Diffusion Equations, V. Lakshmikantham, G. S. Ladde
Existence Of Coupled Quasi-Solutions Of Systems Of Nonlinear Reaction-Diffusion Equations, V. Lakshmikantham, G. S. Ladde
Mathematics Technical Papers
Systems of nonlinear parabolic initial boundary value problems arise in many applications such as epidemies, ecology, biochemistry, biology, chemical and nuclear engineering. Constructive methods of proving existence results for such problems, which can also provide numerical procedures for the computation of solutions, are of greater value than theoretical existence results. The method of upper and lower solutions coupled with monotone iterative technique has been employed successfully to prove existence of multiple solutions of nonlinear reaction-diffusion equations, in special case, by various authors [3,4,5,10,11,15 181. Recently, in [6,17] weakly coupled systems of reaction diffusion equations, when the nonlinear terms are independent …

Doctoral Theses
The study of optimality of block designs formally began with wald (1943) proving a very important optimality property, designated as D-optimality of Iatin Square. Desi gns in a given physical set up. Next Ehrenfield (1955) proved the E-optimality property of Latin Square Designs. Since then, the work in: the area has primarily consisted in evolving a number of useful opti- mality oriteria for oomparing block design in a reasonable set up given and oharacterizing and/or constructing desi gns saiisfying the so called optimality criteria developed. But it was not until 1958, when the theory was given a proper and precise …
