“…One of the areas of geotechnology where abstract mathematical spaces can be utilized is efficient control [11,12,13,14] x Lx (13) and the symptom 2 i p is the "peak-to-peak" parameter given by the relation: In Table 1 are given the distances between the centroids of symptom vectors in the space 9 E with scalable symptoms into the interval 0,1 by using the metric (1). All 9 symptoms are extracted form the concurrent acoustic signal from the process of rotary drilling of five rocks.…”

Hilbert spaces are representing an individual class of abstract mathematical spaces within functional analysis. Hilbert space is infinite dimensional complex space with inner conjunction. Points of this space are functions and by their coordinates is arranged an infinite sequence of functional values of these functions at a certain interval. Algebraic structure of such spaces is giving a place to define, quantify and then analyze geometric relationships between functions which are the vectors of Hilbert space. An aim of the article is to refer to usage of Hilbert space as a state space of process represented by suitable acquired information signal. Space structures are giving a place to classify status of the process and also monitor its dynamics.

The contemporary shaft furnaces for the production of sintered magnesia have a very good performance. However, there are still significant possibilities of their improvement. Thermodynamic, hydrodynamic and rheological processes don't run optimally. The purpose of the research was to determine the reasons and realization of optimization measures. One of the significant requirements was to process materials with lower granularity (20 -40 mm). The improvement was focused on the charging system modification, burner system modification, coke utilization in the central part of the furnace, sinter heat utilization, increasing the insulation. Their verification was reached at the operational conditions. The result was conceptually new pilot shaft furnace, determined for the further research. The basic features of the new shaft furnace are distributed burners improving combustion of the secondary air flowing through the central part of the furnace. By this approach significant improvement of the temperature homogeneity through the furnace cross section is achieved.
