On Lane's Integral

Hill, William James 08 1900 (has links)
The problem and purpose of this paper is to develop Lane's Integral in two-space, and then to expand these concepts into three-space and n-space. Lane's Integral can be used by both mathematicians and statisticians as one of the tools in the calculation of certain probabilities and expectations. The method of presentation is straightforward with the basic concepts of integration theory and Stieltjes Integral assumed.

Openness of Being: The Question Emptiness in Chinese Landscape as seen from Heidegger's Discourse on Art

Lin, Siou-Sia 13 June 2012 (has links)
With respect to art, we mainly discuss the issue of 'space', and we generally believe that there exists the so-called 'art-space'. However, Heidegger considers art in a very different way which is phenomenological. With phenomenological reduction, he reinterprets how the art-space exists, and he also endows art with a brand new meaning, that is, ¡§opening¡¨ , which is the way one expresses oneself. Nonetheless, Heidegger explains art in a dialectical way, that is to say, the negative way. However, that is the reason for Chinese landscape painting to be painted. In this essay, I try to yield further evidence for Heidegger 's theory, by investigating into Chinese landscape painting. The 'art-space' is hidden by the 'blank' spot of the landscape painting, so it is not emptiness, but gathering 'space', 'space itself', and 'light' into a whole; at the same time, it shows truth, which is lived truth. The 'art-space' does not come from imitating, but from a 'text-space' between likeness and unlikeness.

Different Aspects Of Embedding Of Normed Spaces Of Analytic Functions

Bilokopytov, Ievgen 23 August 2013 (has links)
In the present work we develop a unified way of looking at normed spaces of analytic functions (NSAF's) and their embedding into the Frechet space of analytic functions on a general domain, by requiring only that the embedding map is bounded. This is a succinct definition of NSAF and derive from it a list of interesting properties. For example Proposition 4.4 describes the behavior of point evaluations and Proposition 4.6 part (i) gives a general sufficient condition for a NSAF to be a Banach space, which as far as we know, are new results. Also, Proposition 4.5, parts (ii) and (iii) of Proposition 4.6 and Proposition 4.7 are results, which are slight generalizations of fairly standard results, which show up elsewhere in a more specific setting. Some of the facts about NSAF's are stated and proven in a more general context. In particular, a significant part of the material is dedicated to the normed space of continuous functions on a metric space. On the other hand, we provide the necessary background on differential geometry and complex analysis, which further determine the peculiarities in the context of spaces of analytic functions. At the end we illustrate our results on two specific examples of NSAF's, namely the Bergman and the Bloch Spaces over a general domain in Cd. We give a new proof of the reflexivity of the Bergman Space Ap(G, μ) for the case p>1 and of the Schur property of A1(G, μ). We also give new proofs for the equivalences of some of the definitions of the Bloch functions.

Orbital debris : technical and legal issues and solutions

Taylor, Michael W., 1971- January 2006 (has links)
This thesis examines the current technological and legal issues concerning orbital debris (space debris). The unique physical characteristics of the space environment are identified and explained. The thesis then explores the causes of orbital debris and examines the risk posed by debris to the most frequently used orbital areas. Significant environmental, legal, political, and economic consequences of orbital debris are described. The current technical and legal controls on the creation of debris are discussed and evaluated. Finally, proposed solutions are considered and critiqued. The thesis concludes with a non-binding treaty-based proposal for a new legal debris control regime that can encourage compliance and enhance accountability.
