The University of Craiova is a public university located in Craiova, Romania. Founded in 1947, with 4 institutes at the beginning, in the Palace of Justice of Craiova. It is the largest university in the historical Oltenia province of Romania. It was the last university established in the Kingdom of Romania. It was the fifth university in Romania officially approved by the Ministerial Council of the Socialist Republic of Romania in 1965, with 7 faculties: Mathematics, Philology, Electrotechnics, Agriculture, Horticulture, Chemistry and Economics. The university is a member of the European University Association. It currently includes a total of 16 faculties and 2 colleges for undergraduate and postgraduate programms. Professor Dan Claudiu Dănișor is the University's 12th Rector since 2012. The university is governed by a 7-member Vice-Rector. The university is internationally known by its football club FC Universitatea Craiova. Wikipedia.

This paper is trying to clarify recent published results related to a generalized version of 2D Burgers-KdV equation. The generalization consists in considering a nonlinearity of the form un as coefficient of the second derivative uxx. The claim was that the Lie algebra does not depend on n. We show that different algebras correspond to n = 1 and n ≥ 2: One proves that the correct algebra for the case n = 1 depends on four constant parameters and two independent functions. By using similarity reduction procedure, new point-like symmetries and invariant wave solutions of the equation are generated. © 2014 Ed. Academiei Române. Source

Personalized instruction is seen as a desideratum of today's e-learning systems. The focus of this paper is on those platforms that use learning styles as personalization criterion called learning style-based adaptive educational systems. The paper presents an innovative approach based on an integrative set of learning preferences that alleviates some of the limitations of similar systems. The adaptive methods used as well as their implementation in a dedicated system (WELSA) are presented, together with a thorough evaluation of the approach. The results of the experimental study involving 64 undergraduate students show that accommodating learning styles in WELSA has a beneficial effect on the learning process. © 2010 Blackwell Publishing Ltd.

We consider a mixed variational problem involving a nonlinear, hemicontinuous, generalized monotone operator. The proposed problem consists of a variational equation in a real reflexive Banach space and a variational inequality in a subset of a second real reflexive Banach space. We investigate the existence of the solution using a fixed point theorem for set valued mapping. An example arising from Contact Mechanics illustrates the theory. © 2014 Published by Elsevier Ltd.

Intuitionistic fuzzy sets, proposed by Atanassov, have gained attention of many researches for applications in various fields. Different types of similarity measures for intuitionistic fuzzy sets were proposed and used in numerous applications. In this paper we extend some crisp cardinality measures to measures for intuitionistic fuzzy sets; the main role in this process is played by the Frank t-norm family. © 2014 Published by Elsevier B.V.

During the last few years, social media technologies have started to be used for collaborative learning. While most of the case studies reported so far involve a single social media tool or several individual, separate tools, in this paper we advocate the use of an integrated social learning environment, which aggregates several Web 2.0 tools (wiki, blog, microblogging tool, social bookmarking tool, media sharing tools). The platform, called eMUSE, occupies a well defined niche in the landscape of Web 2.0-enhanced learning spaces, providing value-added services for both students and teachers: learner tracking functionality, monitoring and visualization features, grading and evaluation support. A comprehensive rationale underlying eMUSE, a description of the platform architecture and functionalities, as well as an experimental validation in a project-based learning context are provided in the paper. © 2012 Springer Science+Business Media, LLC.
