PROBLEMS OF MODERNIZATION OF PREPARATION OF THE PRIMARY SCHOOL TEACHERS IN TERMS OF STANDARDIZATION OF PEDAGOGICAL EDUCATION

  • TITLE: PROBLEMS OF MODERNIZATION OF PREPARATION OF THE PRIMARY SCHOOL TEACHERS IN TERMS OF STANDARDIZATION OF PEDAGOGICAL EDUCATION
  • AUTHOR(S): G. Olesia
  • ABSTRACT: The article deals with the questions of strategy and technology of creating and realization of the Higher Education standards, which can be regarded as complicated and structural model of professional competence and personal abilities of teacher to realize professional functions. Special attention is centred on the basic and specialized aspects which are related to professional growth and correlation of theo-retical and practical teacher’s preparation.

SIMULATION MODEL OF VOLTAGE INVERTER AS REGULATOR OF VARIABLE CHARACTER LOADS

  • TITLE: SIMULATION MODEL OF VOLTAGE INVERTER AS REGULATOR OF VARIABLE CHARACTER LOADS
  • AUTHOR(S): B. Boichev
  • ABSTRACT: The large number of electronic generators placed in operation and their capabilities determine the cause many researchers to discuss intensively the issue of their use for control of reactive loads. Paper deals with investigation of the possibility of inverters application as regulators of loads with variable character using computer simulations.

MICROWAVE ASSISTED SYNTHESIS OF 2-PIPERIDONE AND 2-PYRROLIDONE- MORPHINANES

  • TITLE: MICROWAVE ASSISTED SYNTHESIS OF 2-PIPERIDONE AND 2-PYRROLIDONE- MORPHINANES
  • AUTHOR(S): D. Vasilev
  • ABSTRACT: The conventional technique of heat is slower and leads to degradation once the products. The use of microwaves not only reduces the reaction time from hours to minutes, but increased the yield and selectivity. These are the reasons microwave organic synthes is can be applied in industry.The microwave heat is very efficient source of energy and can be used to greatly reduce the reaction time of a series of organic reactions. In this work is studied referral codeinone in reactions of hetero-cyclization with 1,3-binucleophiles, with the participation of the α, β-unsaturated ketone system in its molecule.

MONITORING OF E-LEARNING EFFICIENCY

  • TITLE: MONITORING OF E-LEARNING EFFICIENCY
  • AUTHOR(S): L. Skopalik
  • ABSTRACT: E-learning is a priority at European and national level and for TU-Gabrovo. Using attractive modules for e-learning with high quality is with a particular importance. The paper presents the developed approach and the chosen criteria for monitoring of efficiency of e-learning modules. Pilot evaluation of the efficiency of e-learning courses, applying developed methodology and criteria are presented. The results from the monitoring are used for improving e-learning quality.

A NEW NONCONFORMING RECOVERY ALGORITHM FOR TWO-SIDED BOUNDS OF EIGENVALUES

  • TITLE: A NEW NONCONFORMING RECOVERY ALGORITHM FOR TWO-SIDED BOUNDS OF EIGENVALUES
  • AUTHOR(S): A. Andreev, M. Racheva
  • ABSTRACT: In recent papers the authors present and develop an original method for obtaining two-sided bounds of the exact eigenvalues. This idea is based on the combination of nonconforming finite element methods giving lower bounds of eigenvalues and a postprocessing procedure using conforming finite element spaces. Here a new approach is proposed, applicable to second- and fourth-order eigenvalue problems. Namely, a conforming finite element method is used for eigenpairs approximation and then by means of nonconforming recovery interpolant a lower bound approximation of the exact eigenvalues is obtained when the mesh parameter 0h > is sufficiently small. Some appropriate combinations of finite elements (conforming and nonconforming) which fulfil the algorithm are presented and discussed. Numerical experiments illustrating the efficiency of the proposed method are also given.
