Complicated networks can be programmed during a short period of time thanks to high computing power. Network models can be currently used for the sim...

An ecosystem cannot be fully and effectively described simply by simple mathematical rules. Sustainability is difficult to define or measure because it is inherently vague and complex. This paper presents a neuro-fuzzy model, which uses data from different parameters to monitor and assess a certain ecosystem. If classic mathematical methods cannot provide solutions of uncertain data and treating vague situations, a possible solution to represent these conditions may be the use of neuro-fuzzy approach. Therefore, a...

Over the last decades, deep drilling technology expanded fast. Newly created progressive technologies improved quality of drilling work and speeded-up the drilling process. Currently, 75-80 % drilling methods used world-wide are traditional, while 20- 25 % are new techniques. Slovakia is a little behind this trend: our utilization ration shows 95-98 % traditional drilling methods, compared to only 2-5 % new ones. Together with development of new deep-well boring technologies, new types of drilling sets for deep dr...

The acceleration and deceleration periods during each race of a vertical transport installation may be considered as periods of transitional processes where kinematics and dynamic measures variations take place (acceleration, speed and forces) as well as some electric measures (actuating motorпїЅs current). Considering T as the duration of the process, for the minimisation of the installed power, the minimisation of the energy dissipated in the system is imposed during the transitional period: ? ? ? ? ? ? T 2 1 0 ...

The investigation of the fault tectonics in the Kovdor carbonatite intrusion (NW Russia) has resulted in the identification of a new brittle deformations type. It is formed due to the simultaneous turn of fissure planes at discrete angles around two orthogonal guiding lines (axes), where one is represented by a vertical massif symmetry axis (L1), and the other axis (L2) lies horizontally in the fracture plane. Nonetheless, the rotation along the both axes is codirectional, i.e., when moving counterclockwise around...

The theme of this article is analysis of the reinforced concrete arc bridge structure. This article is especially focused on Monier arc bridge. A typical load applied on bridges is moving load, but this type of structure is mainly loaded with surrounding ground mass.

Productivity of geothermal reservoirs is often limited by capability of injection wells due to clogging of near-filter zone or increased viscosity of cooled waters. Especially for highly saline reservoirs, injection of cooled waters to water-bearing formation is often the only way of their disposal. In turn, this phenomena has little importance in case of low-mineralized waters. However, several water-treatment procedures can be used to recover valuable minerals, thus producing diluted water and salt concentrate. ...
