The quantum Yang-Baxter equation ¯rst appeared in theoretical physics and statistical mechanics. Afterwards, it has proved to beimportant also in knot theory, quantum groups, etc. This paper deals with the (colored) Yang-Baxter equation and computational methods. A new result about…

This Special Issue contains selected papers presented at the International Symposium on Understanding Intelligent and Complex Systems - UICS 2009, held on 22-23 October 2009 at Petru Maior University of Targu Mures, Romania.

Object-oriented concepts are useful concerning the reuse of existing software. Therefore a transformation of procedural programs to objectoriented architectures becomes an important process to enhance the reuse of procedural programs. Moreover, it would be useful to assist by automatic methods…

Self-organization is common in natural systems. This tutorialdescribes some of these systems, speci¯cally from insect societies like in bees, termites or ant colonies. In a first part, a modeling process is explained. Objects and phenomena targeted by these methods are…

Pattern recognition aims to classify data (patterns) based ei-ther on a priori knowledge or on statistical information extracted from the data. In this paper we will concentrate on statistical pattern recognition using a new probabilistic approach which makes possible to…

During the last three decades, different types of decompositions have been processed in the field of graph theory. Among these we mention: decompositions based on the additivity of some characteristics of the graph, decompositions where the adjacency law between the…

The paper investigates for some basic contextual factors (suchus the problem complexity, the users' creativity and the problem space complexity) the cognitive complexity associated with modelling the group decision processes (GDP) in e-meetings. The analysis is done by conducting a…

This paper presents three data mining techniques appliedon a SCADA system data repository: Naijve Bayes, k-Nearest Neighbor and Decision Trees. A conclusion that k-Nearest Neighbor is a suitable method to classify the large amount of data considered is made finally…

The proposed transformation module performs mapping be-tween two di®erent knowledge representation forms used in grammar induction systems. The kernel knowledge representation form is a special predicate centered conceptual graph called ECG. The ECG provides a semantic-based, language independent description of…

Photoprotective products are considered borderline betweencosmetics and pharmaceuticals due to physiological implications they have on skin health considering the environmental changes (radiations, global warming, and the diminished ozone layer) and due to the high demands regarding the balance between the…
