IMPACTUL TRECERII LA ECONOMIA BAZATA PE CUNOSTINTE ASUPRA SISTEMULUI EDUCATIONAL ROMANESC

In many countries, the knoledge based economy only just become an important economic theme in public sector, although it has been on the agenda of international conferences on economy for the past five to 10 years. Several countries have been implementing knowledge based economy strategies which have been well documented for public sector. Various surveys of knowledge management practices in education institutions show the increasing awareness of knowledge management as a critical determinant of those organisations performance and its education process quality . They also make evident the increasing use of knowledge strategies, tools and processes in education systems.knoledge based economy, knoledge management, education system, virtual libraries, teaching activities.

On a Generalized Kepler-Coulomb System: Interbasis Expansions

This paper deals with a dynamical system that generalizes the Kepler-Coulomb system and the Hartmann system. It is shown that the Schr\"odinger equation for this generalized Kepler-Coulomb system can be separated in prolate spheroidal coordinates. The coefficients of the interbasis expansions between three bases (spherical, parabolic and spheroidal) are studied in detail. It is found that the coefficients for the expansion of the parabolic basis in terms of the spherical basis, and vice-versa, can be expressed through the Clebsch-Gordan coefficients for the group SU(2) analytically continued to real values of their arguments. The coefficients for the expansions of the spheroidal basis in terms of the spherical and parabolic bases are proved to satisfy three-term recursion relations.Comment: 24 pages, Latex, LYCEN 941

Chaotic SystemsofFractionalOrder

This thesis investigates the bifurcation and stability properties of discrete systems induced by fractional-order continuous chaotic finance systems and Arneodo's chaotic system. The research is structured into four chapters, each focusing on different aspects related to fractional calculus, chaos theory, discretization methods, and the main results obtained from the analysis. Chapter 1 and Chapter 2 provide a preliminary introduction to fractional calculus, presenting the necessary mathematical tools and concepts for understanding the fractional order systems. Additionally, it discusses the fundamentals of chaos theory, emphasizing the significance of chaos. In Chapter 3, various discretization methods are examined to transform the continuous fractional-order chaotic systems into discrete counterparts. The discretization techniques are thoroughly analyzed, considering their impact on the system dynamics and preserving the essential chaotic features during the discretization process. Chapter 4 presents the main results of the thesis. Firstly, it investigates the bifurcation and stability properties of a new discrete system induced from a fractional-order continuous chaotic finance system. Through numerical simulations and mathematical analysis, the chapter reveals the existence of bifurcation points and characterizes their influence on the system's stability. Secondly, a similar analysis is conducted on a discrete system induced from the chaotic Arneodo's system, exploring its bifurcation patterns and stability properties
