The primary aim of this paper is to illustrate the value of visualization in cartography and to indicate that tools for the generation and manipulation of realistic images are of limited value within this application. This paper demonstrates the value of visualization within one problem in cartography, namely the generalisation of lines. It reports on the evaluation of the Douglas-Peucker algor...

Proper relation algebras can be constructed using Z/pZ as a base set using a method due to Comer. The cycle structure of such an algebra must, in general, be determined a posteriori, normally with the aid of a computer. In this paper, we give an improved algorithm for checking the cycle structure that reduces the time complexity from O(p) to O(p).

This paper concerns the estimation of an intertemporal model for labour supply and consumption that recognises the presence of nonworkers and which is cast in a structural optimising framework that allows for uncertainty. Through the utilisation of a micro-data source that measures consumption and labour supply we are able to estimate a flexible preference model which incorporates comer solutio...

Spatially homogeneous Bianchi type-II, VIII and IX anisotropic, as well as isotropic cosmological models can be obtained in a scalar tensor theory of gravitation proposed by Saez and Ballester (1986) when the source for energy momentum tensor is a bulk viscous fluid containing one-dimensional cosmic strings. All the models obtained and presented here are expanding, non-rotating and accelerating...

Improved Complexity of Area Sequence Moments for Mouse Drawn Shapes Vinay Saxena Department of Mathematics, Kisan P.G. College, Bahraich, U.P. 271801, INDIA ______________________________________________________________________________________ Abstract: A mouse drawn shape that is represented by a function of sequence of pixels can be completely specified by the locations of its corner pixels g...

a method for deformation computation based on strain tensor elements, as an alternative to the usual way of application of gradient of displacement vector, is proposed. the method computes directly the strain tensor elements from the computed/observed changes in distances and angles between the stations of a geodetic network in two epochs of observations. displacement vector which is determined...

The Douglas fir terpene alpha-pinene was shown to inhibit the growth of a variety of bacteria and a yeast. Other terpenes of the Douglas fir, including limonene, camphene, and isobornyl acetate, were also inhibitory to Bacillus thuringiensis. All terpenes were inhibitory at concentrations normally present in the fir needle diet of Douglas fir tussock moth larvae. The presence of such terpenes i...

In this article, we obtain two sets of results. The first set results are for the case bi-disc while second describe in part, which these carry over to general poly-disc. A classification irreducible hermitian holomorphic vector bundles D2, homogeneous with respect Möb×Möb, is obtained assuming that associated representations multiplicity-free. Among ones give rise an operator Cowen-Douglas cla...

In this paper, we study a class of Finsler metrics defined by a Riemannian metric and a 1-form on a manifold. We find an equation that characterizes Douglas metrics on a manifold of dimension n ≥ 3.
