The semianalytical method for the calculation of the shape function coefficients which we developed by combining analytical and numerical techniques is now applied to cells with hexagonal symmetry. All values of the / ratio are taken into account and our calculated coefficients are used to...

A coalgebraic, equational approach to the specification of observational structures allowing for a choice in the result type of observations is presented. Observers whose result type is structured as a coproduct of basic types are considered, and notions of covariable, coterm and coequation,...

We investigate a class of Cantor sets, which has the striking property such that their Hausdorff dimensions are strictly less than their packing dimensions, while their corresponding measures, regarded as Borel measures on the sets, are equivalent. Furthermore, we give another class of Cantor...

In this paper, we argue that, although Wittgenstein's reservations on Gödel's interpretation of his own formal reasoning are, indeed, of historical importance, the uneasiness that academicians and philosophers continue to sense, and express, over standard interpretations of Gödel's formal...

In this paper denotes any classical modular Lie algebra of D-type over an algebraically closed field of characteristic 5 associated with an algebraic group of universal type. Irreducible L-modules are dealt with, being remarkably reflected by irreducible modules for C-type appeared in [Ki]....

This paper presents a simple resistant estimator of multivariate location and dispersion. The DD plot is a plot of Mahalanobis distances from the classical estimator versus the distances from a resistant estimator and can be used to detect outliers and as a diagnostic for multivariate normality....

In this paper we present a graphical tool useful for visualizing the cyclic behaviour of bivariate time series. We investigate its properties and link it to the asymmetry of the two variables concerned. We also suggest adding approximate confidence bounds to the points on the plot and...
