The article describes a number of little-known methods for translating natural numbers from one number system to another. The first is a method for converting large numbers from the decimal system to the binary system, based on multiple divisions of a given number and all intermediate quotients by 64 (or another number equal to 2n ), followed by writing the last quotient and the resulting remainders in binary form. Then two methods of mutual translation of decimal and binary numbers are described, based on the so-called «Horner scheme». An optimal variant of converting numbers into the binary number system by the method of division by 2 is also given. In conclusion, a fragment of a manuscript from the beginning of the late 16th — early 17th centuries is published with translation into the binary system by the method of highlighting the maximum degree of number 2. Assignments for independent work of students are offered.

We analyze a problem of formalization a non-repeated decision-making in entrepreneurship when there are exist alternatives with negative outcomes, or losses, one among which does not have dangerous consequences. We consider a problem of modelling the subset of alternatives as variants of risks combinations, in particular, the choice of an optimal variant of the alternative. The proposed model may be exploited for formal justification of the alternative choice during the early stages of non-repeated.

Opening an underground mine or part of it presents complex and responsible issue, which affects the economy and effectiveness of the mine operation. This paper presents a methodology for selecting the optimal variant for opening, the lead-zinc ore mine Toranica, Macedonia. Six variants of opening and haulage of ore and waste rocks in the deeper parts of the ore deposit have been considered. After the performed analysis, the optimal variant for opening and haulage for the Toranica mine was determined.

Abstract The design phase is the most important step of the lifecycle of a technical system. If the manufacture process of any product is based on high quality technical documentation, then there is a chance to achieve a very good product. The paper aims to provide a method for determining the optimal variant of a technical project based on certain technical, economic conditions or terms of use imposed in the early stages of design.

To efficiently move towards a more sustainable dwelling stock in Belgium, priorities need to be defined. Accordingly, it should be questioned if the new policy measure requiring the passive standard for newly built residential buildings from 2020 onwards is justified. This paper emphasises on the energy related aspects of the results of a PhD research. In the research residential buildings in the Belgian context were optimised from a life cycle environmental impact and cost perspective. The results proved that not for all dwelling types and layouts the passive standard is the optimal variant. A well-considered design, orientation and choice of dwelling type will be necessary to make the future requirement of the passive standard technically feasible and efficient.
