This paper presents the design, implementation, and evaluation of a student model in DEPTHS (Design Pattern Teaching Help System), an intelligent tutoring system for learning software design patterns. There are many approaches and technologies for student modeling, but choosing the right one depends on intended functionalities of an intelligent system that the student model is going to be used ...

In our modern society and due to the ever-growing flood of information data mining methods are increasingly applied in many areas. However, often the data is unstructured and not manageable which makes it difficult to extract interesting and relevant information. Data mining methods help find coherences in large data sets and make them useful for humans. In order to interpret new knowledge, it ...

Mushrooms degrade lignocellulosic biomass by releasing lignolytic and hydrolytic enzymes which convert material into soluble low molecular weight compounds are then absorbed as nutrients. In the present study, enzymatic activities of Pleurotus HK 37 during growth on Saba comorensis exocarps were evaluated. It was observed that, has ability to produce enzyme (Laccase) (Carboxymethyl cellulase, x...

developing reliable yet flexible software is a hard problem. although modeling methods enjoy a lot of advantages, the exclusive use of just one of them, in many cases, may not guarantee the development of reliable and flexible software. formal modeling methods ensure reliability because they use a rigorous approach to software development. however, lack of knowledge and high cost practically fo...

In this paper, we investigate the connection between closed Newton-Cotes formulae, trigonometrically-fitted methods, symplectic integrators and efficient integration of the Schr¨odinger equation. The study of multistep symplectic integrators is very poor although in the last decades several one step symplectic integrators have been produced based on symplectic geometry (see the relevant lit...
