This study investigates the impact of pharmacy policies on patient waiting time in the Chemotherapy Day Unit of the Netherland Cancer Institute Antoni van Leeuwenhoek hospital (NKI-AVL). The project evaluated whether a reduction in waiting time resulting from medication orders being prepared in advance of patient appointments was justified, given that medications prepared in advance risked bein...

We present PrologCheck, an automatic tool for propertybased testing of programs in the logic programming language Prolog with randomised test data generation. The tool is inspired by the well known QuickCheck, originally designed for the functional programming language Haskell. It includes features that deal with specific characteristics of Prolog such as its relational nature (as opposed to Ha...

— A very simple formalism, viz. abstract data types, using équations and preconditions, is proposedfor describing the proper tie s oj the object s and the opérations ofa data structure. Two cases studies are detailed: sets, and dictionaries (viz. binary search trees). A small number of rules and heuristics are then developed in order to systematically construct the classical algorithms of searc...

The original description of the k -d tree recognized that rebalancing techniques, such as are used to build an AVL tree or a red-black tree, are not applicable to a k -d tree. Hence, in order to build a balanced k -d tree, it is necessary to obtain all of the data prior to building the tree then to build the tree via recursive subdivision of the data. One algorithm for building a balanced k -d ...

This paper proposes a real time Automatic Vehicle Location (AVL) and Monitoring system for pilgrims road transport coming towards city of Makkah in Saudi Arabia based on Data Distribution Service (DDS). This service is a real time publish/subscribe middleware. Using this middleware approach, we are able to locate and track a huge number of mobile vehicles and identify pilgrims for an annual Isl...

Classification is considered as one of the building blocks in data mining problem and the major issues concerning data mining in large databases are efficiency and scalability. In this paper we propose a data classification method using AVL trees enhances the quality and stability of data mining problems. Researchers from various disciplines such as statistics, machine learning, pattern recogni...

The paper presents an inside-out method for conformal meshing of multiple domains in contact applicable to meshes consisting of arbitrary polyhedra. The method is automatic and does not require high-quality surface triangulation. It is an extension of AVL’s automatic polyhedral mesh generator FAME with an additional step during which the cells are distributed to their domains and the internal i...

The focus of this installment of the Educator's Corner is on tree construction – red-black trees. Some of the material for this column is taken from Chapter 13 of the forthcoming book " Modern Software Development Using C#/.NET " by Richard Wiener. This book will be published by Thomson, Course Technology in the Fall, 2005. A fascinating and important balanced binary search tree is the red-blac...
