This paper presents a theorem concerning a matroid with the parity condition. The theorem provides matroid generalizations of graph-theoretic results of Lewin [3] and Gallai [1]. Let M=(E, F) be a matroid, where E is a finite set of elements and F is the family of independent sets of M (in this paper, we presuppose a knowledge of matroid theory; our standard reference is Welsh [4]). Assume that...
Ilex paraguariensis St.Hil. é uma espécie de importância econômica tendo em vista sua utilização na região meridional da América do Sul no preparo do chimarrão, uma bebida estimulante, preparada pela infusão de suas folhas e talos moídos. Este trabalho apresenta a análise de metilxantinas em folhas de I. paraguariensis e outras espécies de Ilex freqüentemente relatadas como adulterantes. A dete...
methods for estimating the means and covariances of stumpage prices and incorporating _._ th m in harvest scheduling models. We approached the esti ation problem by fitting timeseries models to loblolly pine sawtimber and pulpwood stumpage prices in Georgia, USA, _= and deriving formulas for means and covariances of price predictions. Statistical evidence _ supported integrated autoregressive m...
Previous studies on sex-differentiated mate preferences have focused on univariate analyses. However, because mate selection is inherently multidimensional, a multivariate analysis more appropriately measures sex differences in mate preferences. We used the Mahalanobis distance (D) and logistic regression to investigate sex differences in mate preferences with data secured from participants res...
The aim of the paper is to derive the numerical least-squares esti-mator for mean and variance of random variable. In order to do so the following questions have to be answered: (i) what is the statistical model for the estimation procedure? (ii) what are the properties of the estimator, like optimality (in which class) or asymptotic properties? (iii) how does the estimator work in practice, ho...
WASTE NOT William Edwards Deming, the first child of William Albert Deming and Pluma Irene Edwards, was born on 14 October 1900 in Sioux City, Iowa. His father worked mainly in freelance legal work and his mother gave music lessons on their grand Kimball piano. As a child, Deming grew up in meagre conditions. He and his family lived for years in a tarpaper shack. As a boy he worked at a hotel f...
This paper describes the state of the art of coding schemes for dialogue acts and the efforts to establish a standard in this field. We present a review and comparison of currently available schemes and outline the comparison problems we had due to domain , task, and language dependencies of schemes. We discuss solution strategies which have in mind the reusability of corpora. Reusability is a ...
