Lifting transonic full-potential flow is investigated using a streamfunction formulation which combines grid generation and flow physics into a single equation for the transformation metric. Supercritical calculations are carried out using the modified density method to provide numerical...

The paper deals with the methodology of managing the development of large-scale systems and covers problems of designing large-scale production/transportation systems and their development control. It also discusses some of the results in this field obtained by the author. A specified feature of...

This paper contains formalized models which provide determining the expediency of DDB (distributed databases) designing for the considered set of users, designing of external model of users' subject scope and of the generalized external model (GEM) of DDBs, normalization of GEMs, obtaining...

The possible variants of CAD system structure development is examined. These variants are based on the mainoperations of its algorithm functions and differs in its user characteristics. The classification of CAD-systems is carried out based on functional properties.

We define modified importance sampling and discuss conditions under which variance reduction is possible relative to the Crude Monte Carlo method. Application of modified importance sampling to the “what if” problem and to sensitivity analysis of discrete-event systems are given. Numerical...

The information system ABLAK program package consists of a collection of application programmes for serving a single office Bureau. The ABLAK database is managed by the LATOR database management system.

LATOR is a general purpose database management system for establishing and maintaining a database environment for a set of computers connected in a local area network. Consistency of data structures is preserved automatically. The philosophy of LATOR is different from that of the commercial...
