We define and study odd analogues of classical geometric combinatorial objects associated to permutations, namely Schubert varieties, diagrams, inversion sets. show that there is a bijection between sets permutations acyclic orientations the Turán graph, dimension variety permutation length permutation, give several necessary conditions for subset [n]×[n] be diagram permutation. also sign-twist...

This article demonstrates how you can make use of the tools that have been provided for on-line querying of data resources. These tools rely on others (such as the NLM and NCBI) providing and documenting appropriate web interfaces. The tools described here allow you to either retrieve the data (usually in XML) or have it rendered in a browser on the local machine. To do this you will need the B...

INTRODUCTION Currently, most data warehouses are being used for summarizationbased, multi-dimensional, online analytical processing (OLAP). However, given the recent developments in data warehouse and online analytical processing technology, together with the rapid progress in data mining research, industry analysts anticipate that organizations will soon be using their data warehouses for soph...

Quickly transmitting large datasets in the context of distributed computing on wide area networks can be achieved by compressing data before transmission. However, such an approach is not efficient when dealing with higher speed networks. Indeed, the time to compress a large file and to send it is greater than the time to send the uncompressed file. In this paper, we explore and enhance an algo...

the overall purpose of this paper is to evaluate the effectiveness of personality attributes as predictors of consumer behavior in contrast to traditional demographic variables in the digital environment. new variables were needed to replace the traditional ones. this research evaluated three groups of consumer behaviors and examined personality and demographic variables. the primary data colle...

Das Ziel des „my-X“ Projektes besteht darin: Analysewerkzeuge online in Form von „pre-paid“ Konstruktion anzubieten. Im folgenden Beitrag werden die wichtigsten Charakteristika über das (seit Januar 2007 erstellte) System dargestellt. Diese Informationen betreffen einerseits kurz die technische Realisierung, andererseits umfangreicher die Erfahrungen der Referenzund Testprojekte (bis Ende Oktob...

Parents of children with autism spectrum disorders (ASD) experience very heightened levels parenting stress. Symptoms ASD, attention deficit hyperactivity disorder (ADHD), and oppositional defiant (ODD) vary in diagnosed ASD. The current study examined ADHD, ODD symptoms an ASD sample through a hierarchical linear regression to determine which accounted for the greatest proportion unshared vari...
