The methodology of sustainable forecasting of runoff and diagnosing bifurcations of its formation, being considered in the article, allows solving fundamentally new hydrological problems (including problems of engineering hydrology) related to the possibility of obtaining long-term estimates of the probabilistic characteristics of long-term river runoff under the conditions of evolutionary changes in the runoff formation factors (climate and anthropogenic activity on catchments). Currently, these long-term estimat...

The MEMS technology has experienced an amazing growth since the mid-20th century, becoming a major presence in current technologies. The MEMS devices refers to microstructures that are based on both electrical and mechanical components. Given their multiple applicability, made the demand on market to increase, resulting the rapid development of this technology. With a wide opening in the field of navigation, MEMS devices are based on accelerometers and gyros, but also on sensors such as magnetometers, environmenta...

Research goal of the paper is mathematical description of the physical process of forming the surface waters quality on the example of the Lower Section of the Ingulets River. The methodology in which the chemical status of a water body (category and class of water quality) is assessed based on the analysis of observational data (concentrations of priority hazardous pollutants) was used. Based on a general assessment, the suitability of surface waters for use in various economic purposes is established. We propose...
