Generation of equations for shell models of turbulence in the Maple system

The paper describes a technology for the automated compilation of equations for shell models of turbulence in the computer algebra system Maple. A general form of equations for the coefficients of nonlinear interactions is given, which will ensure that the required combination of quadratic invariants and power-law solutions is fulfilled in the model. Described the codes for the Maple system allowing to generate and solve systems of equations for the coefficients. The proposed technology allows you to quickly and accurately generate classes of shell models with the desired properties.

Automation of instruction sheets on attention devices and signaling circuits compilation

Objective: To study the compilation of instruction sheets on devices and methods of its automation. Methods: Methods of information theory were applied, as well as graph theory in order to present technical documentation in electronic form. Results: Current experience of compiling instruction sheets on attention devices and signaling circuits (ADSC) was analyzed. The main steps of new instructions elaboration were considered, as well as the specificities of approval procedure of instruction sheets on ADSC devices. The causes of error occurrence in the process of instruction sheets compilation were described in the article. Prerequisites for automation of instructions compiling process were analyzed. The issue of access to documentation data in branch format was discussed separately. Algorithms of automated compilation of instruction sheets on ADSC devices were developed. The functioning of automation module of instructions’ compilation was described. Practical importance: Application of the module proposed in the article allows for the solution of manual instructions’ compilation problems and the reduction of expenses on technical documentation maintenance of ADSC devices. The problems of current approach to compilation of instruction sheets on ADSC devices were described. The automation methods were suggested, the former will make it possible to move to a new level of application safety of modern approaches to planning and maintaining of technical documentation.
