The restricted two-body problem in constant curvature spaces
We perform the bifurcation analysis of the Kepler problem on and .
An analogue of the Delaunay variables is introduced. We investigate the motion
of a point mass in the field of the Newtonian center moving along a geodesic on
and (the restricted two-body problem). When the curvature is small,
the pericenter shift is computed using the perturbation theory. We also present
the results of the numerical analysis based on the analogy with the motion of
rigid body.Comment: 29 pages, 7 figure
Trajectory and stability of Lagrangian point in the Sun-Earth system
This paper describes design of the trajectory and analysis of the stability
of collinear point in the Sun-Earth system. The modified restricted three
body problem with additional gravitational potential from the belt is used as
the model for the Sun-Earth system. The effect of radiation pressure of the Sun
and oblate shape of the Earth are considered. The point is asymptotically
stable upto a specific value of time correspond to each set of values of
parameters and initial conditions. The results obtained from this study would
be applicable to locate a satellite, a telescope or a space station around the
point .Comment: Accepted for publication in Astrophysics & Space Scienc
Modern pedagogical technologies in the system of additional professional education
The text of this article reflects the results of theoretical and practical research in the field of equipping the system of additional professional education with the means of modern pedagogical technologies that affect the quality of professional training of future specialists. The most relevant pedagogical technologies are considered separately, and their effectiveness or ineffectiveness is confirmed by means of online questionnaires. Besides, a significant segment of the study is devoted to reviewing and comparing the experience of predecessors in this matter. The role of personality –oriented and competence-based approaches in the system of additional vocational education is revealed and actualized, their individual elements, especially significant for research, are singled out. A special place in the structure of the study is occupied by the chosen key method – online questionnaire, which is based on data provided by more than 150 teachers of the systems of both higher professional and additional professional education. All of them are not geographically tied to one place, in connection with which one can judge the objectivity of their opinions, as well as the vast geography of the dissemination of the research results. This method is one of the most effective and promising methods of scientific analytical and reflective research
