  • Annals of Mathematics In this paper we will solve one of the central problems in dynamical systems: Theorem 1 (Density of hyperbolicity for real polynomials). Any real polynomial can be approximated by hyperbolic real polynomials of the same degree. Here we say that a real polynomial is hyperbolic or Axiom A, if the real line is the union of a repelling hyperbolic set, the basin of hyperbolic attracting periodic points and the basin of infinity.

  • In the military, you cannot fight a battle without ammunition, guns, food and transport. This is an aspect of logistics. Similarly, you cannot run a project without certain requirements, e.g. you cannot develop a curriculum without a budget, subject experts, students to benefit from the curriculum, and so forth. Project Risks Project risks are the anticipated and unanticipated obstacles that might arise in the course of a given project. A risk analysis is conducted in order to isolate the most likely ones, and involves answering the question: “What could go wrong?” ...

  • Between the covers of this remarkable text one can experience, at near warp speed, a journey through the cosmos of subject matter dealing with dimensioning and tolerancing of mechanical products. The editor, as one of the contributing authors, has aptly summarized the content broadly as “about product variation.” The contained chapters proceed then to wend their way through the various subjects to achieve that end.

  • For centuries the human race has noted and recorded for the following purposes: memory; communication; problem solving and analysis; creative thinking; and summarisation, etc. The techniques that have been used to do this include sentences, lists, lines, words, analysis, logic, linearity, numbers, and monotonic (one colour) usage. Good though some of these systems seemed, they have all used what you know to be the dominantly 'left cortical' thought modalities.

  • Polymer nanocomposites are commonly defined as the combination of a polymer matrix and additives that have at least one dimension in the nanometer range. The additives can be one-dimensional (examples include nanotubes and fibres), two-dimensional (which include layered minerals like clay), or three- dimensional (including spherical particles). Over the past decade, polymer nanocomposites have attracted considerable interests in both academia and industry, owing to their outstanding mechanical properties like elastic stiffness and strength with only a small amount of the nanoadditives.

  • Nanomaterials, characterized by at least one dimension in the nanometer range, can be considered to constitute a bridge between single molecules and infinite bulk systems. Besides individual nanostructures involving clusters, nanoparticles, quantum dots, nanowires and nanotubes, collections of these nanostructures in the form of arrays and superlattices are of vital interest to the science and technology of nanomaterials.

  • The discourses and institutions of human rights are contemporary devices for bringing morality to bear on the harsh realities of political, economic and social life. These attempts to render the conditions of human existence more tolerable and more dignified tend to focus mainly on the role of domestic and international law and the conduct of states and the international institutions that represent them.

  • We Americans assume that our economic system will always scamper to provide us with the products we want. Special orders don’t upset us! I want my MTV!

  • The statistical analysis of multivariate data requires a variety of techniques that are entirely different from the analysis of one-dimensional data. The study of the joint distribution of many variables in high dimensions involves matrix techniques that are not part of standard curricula. The same is true for transformations and computer-intensive techniques, such as projection pursuit.

  • At the global level, the relationship between population and environ- mental impact is not easy to test in a way that leads to reliable and non- spurious estimates. This is because of the lack of data on environmental degradation covering a sufficiently large number of countries over a suffi- ciently large period of time. It is for this reason that studies have tended to focus on CO2 emissions and energy use, for which cross-country and time- series data are available.

  • Our goal is to develop automated methods for the segmentation of threedimensional biomedical images. Here, we describe the segmentation of confocal microscopy images of bee brains (20 individuals) by registration to one or several atlas images. Registration is performed by a highly parallel implementation of an entropy-based nonrigid registration algorithm using B-spline transformations. We present and evaluate different methods to solve the correspondence problem in atlas based registration.

  • We have attempted to improve and update this text while retaining the features that make it unique, namely, an emphasis on physical understanding, and the ability to estimate, evaluate, and predict results without blind reliance on computers, while still maintaining rigorous connection to the mathematical basis for quantum chemistry. We have inserted intomost chapters examples that allowimportant points to be emphasized, clarified, or extended. This has enabled us to keep intact most of the conceptual development familiar to past users.

  • This paper is about a class of strange attractors that have the dual property of occurring naturally and being amenable to analysis. Roughly speaking, a rank one attractor is an attractor that has some instability in one direction and strong contraction in m−1 directions, m here being the dimension of the phase space. The results of this paper can be summarized as follows. Among all maps with rank one attractors, we identify, inductively, subsets Gn, n = 1, 2, 3, · · · ,

  • Access to library materials and services, on one dimension, is represented in the location of physical facilities. Because libraries are traveled-to outlets, marketing location theories can be applied successfully to library siting. (Wood and Koontz) accountability Libraries like private sector businesses are increasingly called upon to make all units accountable for results. Growing funds are needed for technology as opposed to only books. Funders often cut the library budget first, in favor of other agencies such as police and fire or other seemingly, more necessary agencies.

  • AMATH 581 Homework 2 Shallow Liquid Simulation Erik Neumann 610 N. 65th St., Seattle, WA 98103 erikn@MyPhysicsLab.com November 19, 2001 Abstract A model of shallow fluid behavior is evaluated using a variety of numerical solving techniques. The model is defined by a pair of partial differential equations which have two dimensions in space and one dimension of time. The equations concern the vorticity ω and the stream function ψ which are related to the velocity field of the fluid. The equations are first discretized in time and space.

  • Note immediately one difference between linear equations and polynomial equations: theorems for linear equations don’t depend on which field k you are working over, 1 but those for polynomial equations depend on whether or not k is algebraically closed and (to a lesser extent) whether k has characteristic zero. Since I intend to emphasize the geometry in this course, we will work over algebraically closed fields for the major part of the course.

  • One highly conspicuous crop of examples of mental phenomena related to the non-existent is of course yielded by our experience of works of art. It is therefore somewhat surprising that Meinong himself does not apply his theory of non-existent objects to the working out of a detailed theory of the ontology and psychology of aesthetic phenomena. This task was however carried out by one of his most prominent disciples, Stephan Witasek, in his masterly Grundzüge der allgemeinen A " sthetik of 1904.
