One of the main factors for the knowledge discovery success is related to the comprehensibility of the patterns discovered by applying data mining techniques. Amongst which we can point out the Bayesian networks as one of the most prominent when considering the easiness of knowledge interpretation achieved. Bayesian networks, however, present limitations and disadvantages regarding their use an...

Fungal cellulases offer advantages of a secreted enzyme complex and relative easiness and economy of producing enzyme. Considerable amount of work has been done on fungal cellulases, especially with resurgence of interest in biomass-ethanol and concept of bio-refineries. Significant information has also been gained on basic biology of organisms producing cellulases, and in process development f...

A simple model for the dynamics of dunes is introduced. The model simulates formation processes of typical shapes dunes: transverse dunes, barchans, seif dunes, star dunes, parabolic dunes and elongated parabolic dunes according to several environmental factors. The results have qualitative correspondence to the real systems. Considering the simplicity of the algorithm and the consequent easine...

This work aims at presenting, in a comprehensive manner, several approaches to model and simulate closed loop topologies using the classical Lagrangian formulation. One of great advantages approach is its simplicity easiness obtaining equations motion. However, critical aspect arises when mechanical systems include topologies, since process deriving motion becomes complex task. The key point pr...

Tiif, rectal route for anaesthesia has been long under consideration. The first efforts in this direction were made by F. Roux in1846. The undeniable advantages of the rectal route, the easiness of administration, the avoidance of choking and excitation, and freedom from complications, opened up the way for further research. Injury to the bowel wall was the great danger in the experiments of Ro...

Ontologies have recently received popularity in the area of knowledge management and knowledge sharing, especially after the evolution of the Semantic Web and its supporting technologies. An ontology defines the terms and concepts (meaning) used to describe and represent an area of knowledge.The aim of this paper is to identify all possible existing ontologies and ontology management tools (Pro...

In this paper, we evaluate popular Web-based tools for test design, implementation, delivery, automatic grading and result analysis. We compare these tools with respect to the variety of question types that support, the capabilities for multimedia use, the security, the easiness of development, maintenance and delivery of tests, the automatic grading and the statistical analysis of the results....

We present a review of the various integer linear programming (ILP) formulations that have been proposed for the routing and wavelength assignment problem in WDM optical networks with a unified and simplified notation under asymmetrical assumptions on the traffic. We show that all formulations proposed under asymmetrical traffic assumptions, both link and path formulations, are equivalent in te...
