Ecological and resort area of Caucasian Mineral Waters occupies a special place among the resort regions of Russia due to the richness, diversity, quantity and value of mineral waters, landscape and climatic conditions, therapeutic muds. The pace of development of mineral water resources for the resort and industrial bottling has recently increased. The increase in the number of enterprises for bottling mineral water and organizations of sanatorium-resort type has a significant impact on the growth of water intake...

The concepts of danger, uncertainty and risk are often used intuitively and inaccurately not only in common language but also in the media where it is unfortunately commonplace and last but not least in scientific circles. The clan defines uncertainty, danger and risk, and graphically visualises the aspects it encompasses. The graph is defined by two dimensions, namely probability and objectivity. The notion of danger is the least unequivocal. This is an object property that is a threat. Uncertainty was mathematic...

The article deals with the synthesis of a closed distributed control system for the drill temperature field. The technique is developed on the basis of the the temperature fields control function. The analysis and modeling of the drilling process during the passage of the drill through the variable environment (ice-ground-ice-water-ice) are performed with taking into account the drill heating. To increase the productivity of the passage, it is proposed to use sectional heating of the drill instead of the existing ...

The transition to advanced digital, intelligent production technologies, the creation of systems for processing big amounts of data, machine learning and artificial intelligence is caused, among other things, by the need to move to a new level of digital energetics, which ensures the interrelationship between the generation, distribution and consumption of energy resources and their effective management. The efficiency of the use of energy resources is one of the urgent problems in the energy sector. One of the pr...

In order to ensure energy security, at national level, coal constitutes an important source, though its share in the energy mix is reduced in the past few years in favor of clean technologies and on the background of the fall in the energy consumption. Where can be located in the project of energy security, the production of coal, exploited in the mining units in the Jiu Valley and valorized at the two power plants, Mintia and Paroseni-components of the Hunedoara Energy Complex, amid the request for intervention f...

The paper mentions performance evaluation of thermal solar power plants in conditions of Belgorod region of Russian Federation. The main task is thermal energy production determination of vacuum solar collector in environmental conditions of Belgorod region of Russia. For quantity of heat calculation of thermal solar power plant it is taking into account solar radiation (insolation) changing in different seasons, collector angulation and sun ray angle change in different time, amount of clouds, coefficient of effi...

The paper deals with the analysis of the design elements of the road at the crossing point of the railway line. For the analysis were selected existing level crossings in the Czech Republic, where problems were found during the traffic. These were mainly problems of repeated disorder road pavement in contact with the construction of the level crossing. In addition, there are problems with the crossing of motor road transport or freight traffic. Particularly in the case of longer vehicles (heavy goods vehicles, pub...

Paper focuses on methodology for preprocessing of transactional data from public transport system the in region as administration unit of the Czech Republic. The aim is to present synthetic information in GIS information system. Necessary data sources are defined and evaluated. Target group of users are those who plan development of public transport system. Information covering state of each bus or other mean of transport (number of passengers categorized by tariffs between any stops of the bus line) and activitie...

In the present study, an image porcessing analysis of porosity in some iron-based powder materials was proposed. The specimens analyzed were produced from atomised iron powders of different sizes ( 150 ?m). The analyzed powders were compressed in a mold using uniaxial pressing and the applied pressure was 600 MPa with the disc dimensions of ? 8 ? 6 mm. The compacts were sintered at a temperature of 1.150 °C with the sintering time of 60 and 90 minutes. The sintered specimens obtained were analyzed regarding the po...

This article is referring to an analysis regarding the skating temperature variation and the electrical power energy consumption obtained by a removable outdoor ice rink, which was seasonal installed in the exterior of a big size commercial building in Romania. The electrical energy power consumption was performed during a period of five years, between 2014/2015, 2015/2016, 2016/2017 and 2017/2018, starting with the 15th of November and ending with the 15th of March, each period. The skating rink temperature varia...

In the Czech Republic, mining is regulated by a number of laws and decrees. The basis of this article is the approximation of legal provisions and their quantitative expression, the legal provisions applied in the area of economical exploitation of mineral resources in our territory. The provisions of the Upper Law are based on four fundamental principles and, on the basis of these principles, the provisions regarding the economical exploitation of mineral resources can be assigned to the individual principles. Am...
