Computing experiment for simulating altitude-latitude distributions of ionospheric parameters
AbstractA mixed derivatives influence in during three-dimensional simulation of ionosphere by difference methods is considered.
A mixed derivatives influence in during three-dimensional simulation of ionosphere by difference methods is considered.
Moisture transport in soils under conditions of drainage on the basis of an agreed account of the capillary and the description of moisture transfer on porous surfaces is simulated.
The fundamental solution of a Cauchy problem and the spectral task for a one-dimensional Schrodinger equations with potential in the form of polynomials m P (x) (m 6) is solved. Numerical calculations are applied to modelling adiabatic potentials with two minima characteristic for a proton in compounds with intramolecular hydrogen bonds.
Client-side optimization methods are very efficient to improve performance of web resources of culture organizations. In comparison to server-side optimization these methods are related to frontend architecture only and can’t be achieved only with additional hardware.
General requirements of visualization systems and their role in scientific calculations are covered. The architecture and capabilities of Visualization Toolkit (VTK) are described. Input data formats and some calculation results are described. List of mature visualization systems used VTK is considered.
A new approach for evaluating the quality of University timetables is proposed. This approach uses a multicriterion expert system with two quality
indexes: the average penalty imposed on timetabling and highest penalty imposed on one of the constraints. The system based on a series of intelligible rules and use the algorithms of fuzzy logic for getting the final evaluation of timetabling was created. An algorithm for searching a set of Pareto optimal timetables based on the Pareto simulated annealing algorithm is constructed.
