Investigations of propagation, reflection and action on plasma of stochastic electromagnetic radiation

The broadband generator of stochastic electromagnetic oscillations in a decimetric band of waves lengths with output power ≈ 0,3 W is described. The epitaxial-planar VHF transistors of КТ911 type terminated by ring microstrips are used as an active elements. Electrical and amplitude-frequency characteristics of the generator are given. Spectral characteristics of oscillations were investigated by methods of correlation and phase-frequency analysis. We established, that oscillations have non-regular character with appreciable phases jumps.. The stochastic VHF oscillation with such characteristics will be used for investigation of its transmission, reflection and action on plasma

Comparative Pedagogical Analysis of Teacher Education Programs in France And The USA

This article presents the results of comparative pedagogical studies that aim at determining the general and specific features of teacher education programs in France and the US. The study is based on binary comparisons and classical methods of comparative pedagogy, including comparative, descriptive and inductive-deductive. In the course of the study, the authors of the article determined conditions for efficient teacher training that are common to the French and US systems of higher education; established the key factor causing the specific functioning of education systems in France and the US; indicated the priority directions of designing teacher education programs in France and the US. The authors have interpreted the study results with due regard to the competency-based educational paradigm and determined trends that condition the general laws of designing educational programs
