  Is devoted to the actual problem of constructing classifiers objects given by a point in a multidimensional space of feature values. A version of the geometric separation of sets by hyperplanes normal to the center-distance data sets. This approach to separating planes reduces the computational operations performed. This author separability criterion allows a normal quite effective in terms of computational complexity the exact solution of the normal separation, which requires only a linear search of points separated sets. Proposed in the article the approach to classification of sets in the multidimensional space of values ​​of their attributes can be used as a starting point for building effective in terms of computational complexity classification not only for normally separable sets, but also for more complex variations thereof. This is the most significant practical importance of materials submitted by the authors.

"Construction production is connected with emergence of a number of negative impacts on environment. In article main types of the construction works, being accompanied the main are considered by loads of ecology. The special attention is given to a problem of construction garbage, options of a solution with a dump. Versions of the solution of a question of utilization of construction garbage - sorting, processing. Economic aspects of a solution with utilization of construction garbage: Ekonolmiya of materials, decrease in quantity of a waste. "

Results of the flight research spent in April - among students of RSUCE are brought May, 2012. The Main objective of research - definition of the emotional relation of students to local and central political orders. Primary data are received by questioning on a method of semantic differential. By the received results semantic portraits of four types of political usages (two ideal constructions and two above-stated real orders), relative distances in semantic space between images of these usages are defined. That has allowed to calculate levels of emotional perception of local and central political usages in linear approach.

Keywords: questioning, semantic differential, affective component, group installation, political order, level of emotional perception
