A mathematical model has been constructed that makes it possible to determine operational characteristics of the pneumatic drive and select design parameters of simulator elements.

As a result of calculating characteristics of the sports simulator pneumatic drive some drawbacks have been revealed in pneumatic equipment. For this very reason an original design of pneumatic control element with improved characteristics has been developed and its flow diagram is given in the paper.

One of the most important values while forming gear wheels is a material section area S_с which is to be removed by a tool in the process of forming a space between two teeth in one pass. Cutting resistance which is proportional  to section area of  the layer to be cut and, correspondingly, a thermodynamic intensity in the polishing zone depend on S_с value.

The paper proposes relations for calculation of a material section area S_с which is to be removed from a blank while forming a space between two teeth of a satellite gear of a planetary pin tooth reducer.

Measurements being made in the AutoCAD packet have shown that any corrections of the profile do not make a significant influence on a section area S_с.

The paper proposes a scientific and innovative approach to solution of an important problem in the field of rational nature management and ecology which presupposes realization of evaluation, analysis and monitoring of environment  quality  (EQ) in Belarus.  This  approach is based on methods and  facilities  of  administrative-command  and  partially  automatic-control  management.   The  main components of the innovative approach are an automatic  system for  evaluation and monitoring of EQ including estimation and formation of nature-resource potential within 11 cadaster and other data base, general principles on evaluation and monitoring of EQ, structural and algorithmic schemes for evaluation of ecological state of administrative territories, calculation of generalized indices of nature-territorial complexes and solution of nature protection problems in respect of EQ monitoring. A system of equation calculation for the analysis and evaluation of technogenic load on main nature components of the environment (free air, water objects, soil cover), realization of monitoring function in respect of EQ and ecological state of local and urban territories, nature resources  and enterprises, pollution and state of some recipients and also data resources for execution of analytical calculations and functions directed on monitoring quality of nature components of the environment is advanced in the paper.

Optimization of currency portfolio structure of export industrial enterprises in the Republic of Belarus, by which we shall understand a currency structure of export contracts of an international enterprise, is considered as one of the most important problems in the financial management of an enterprise. Statement and analysis of industrial enterprise alternative costs and simultaneous investigation of tendencies pertaining to changes in the exchange rates give the possibility (under other equal status) to reduce non-systematic risks in foreign trade. Diversification of industrial enterprise currency portfolios with the purpose to decrease financial risks and with due account of exchange rate correlation can lead to an increase of payments in Russian currency and Eurocurrency under enterprise export contracts. The given changes decrease currency risks in the foreign trade however they entail possible increase of the export share of products to the Russian Federation in total export volume of the Republic of Belarus that increases dependence of the Republic of Belarus on the Russian Federation as the main foreign trade partner.
