It is well known that multiplication inside a computer does not follow the associative property because of roundoff effects. possible to use this fact generate other different chaotic instances maps or oscillators when three terms appears. Chaos very sensitive small changes in initial conditions and amplifies these rounding We condition build instances, which give results, Lü oscillator 2D map,...

Ontologies are widely used in many domains and evolve as domains change [7]. From the other side, the relational database technology has ensured the best facilities for storing, updating and manipulating the information of problem domain. We propose in this paper a transformation process from existing data in relational databases into OWL class instances using XSLT. This process allows us to ma...

Making business processes accessible to users constitutes a crucial challenge throughout their entire life cycle: users should be enabled to understand business process models ( Analysis & Design phase), keep an overview on running process instances ( Operation phase), perceive process adaptations ( Operation phase), and comprehend as well as interpret results of analyzing processes ( Evaluatio...

The usefulness of process models (e.g., for analysis, improvement, or execution) strongly depends on their ability to describe reality. Conformance checking is a technique to validate how good a given process model describes recorded executions of the actual process. Recently, artifacts have been proposed as a paradigm to capture dynamic, and inter-organizational processes in a more natural way...
