W publikacji zaproponowano matematyczny model i algorytm określenia zbilansowanej dawki pokarmowej dla krów mlecznych. W pracy przedstawiono korektę matematycznego modelu i opracowano algorytm programu bilansowania dawek pokarmowych. Opracowany model i algorytm pozwalają wyznaczyć dobowe zapotrzebowanie organizmu zwierzęcia na składniki pokarmowe i mikroelementy z uwzględnieniem zestawu pasz, planowanego...
This article provides a list of errors methodology national income to fulfill international standards: the system of national accounting (SNA-93), the European System of Accounts (ESA-95) and the updated version of the SNA-93 – SNA 2008. On the example of the Russian Federation published statistics showing the absolute and relative size of distortions calculated values of national income as used in...
In precision joints complementarity of details is incomplete in most cases (usually group), that leads to essential complication of assembly process and it is accompanied by decline of productivity and work in progress occurrence. Values of these losses can be steered, but it is connected with additional complications of assembly technologies and expenses for their realization. There is a problem...
There is a description of the question of a decrease in costs for transportation of products in machine-assembling production in this article. This decrease is based on the procedure, which is offered by the author and is founded on optimization of material flows on a production section due to a rational arrangement of the technological modules on it. The developed procedure of construction of schemes...
An optima procedure for synthesis of multiproduct reactor systems is suggested. The first step is to determine theoretically possible values of product sellectivities for given market demand and reaction scheme. At this stage the processing power for supplied material is given. The second step is to determine reactors constructional, regime and structural parameters delivering sellectivities values...
This topic deals with the possibilities of using basic excavation machines for tilling ground on high and steep roadbed slopes, especially for excavations or embankments of railways' and motorways' roadbed slopes. Dynamics' simulation of these machines taking into account the vibration of excavation bucket causing of engine's vibration has been presented. This simulation model enables to define real...
