Systemtechnik des Schienenverkehrsmination algorithms. The framework loosely follows the AI search paradigm — exploring the space of formulas derived from the input by applying various rewriting operators in search of a problem formulation that will be good input for the intended Q.E. program. The only operator provided by the proto

Grundbegriffe des Schienenverkehrs,d in calculation engine. It obstructs extensive usage of such systems because of requiring special knowledge and skills, e.g., in programming, to use them. Another problem of computer algebra systems is multitude of data formats and the implied difficulty in simultaneous usage of different systems.

Systemtechnik des Schienenverkehrs existence and stability of the rhombus-like central configurations in Newton 9-body problem, which consists of two homothetic rhombuses, is studied. It is proved that these central configurations are unstable. All computations are executed by means of computer algebra system Mathematica.

Systemtechnik des Schienenverkehrselestial mechanics, astrodynamics, and other natural sciences. Before appearance of Programming Systems such as . etc., we knew for classical Newtonian three-body problem only Euler exact collinear and Lagrange triangular solutions, for many-body problem – the rotating regular tetragon solution foun

Steuerung und Sicherung der Fahrwegelemente,se of two equal masses there can exist central configurations in the form of isosceles triangle with three bodies being in its vertices and the fourth body being situated in the axis of symmetry inside or outside the triangle. The number of possible configurations in such cases depends on the masses
