Neural models in diagnostics of the financial result of housing and utility enterprises
Published 2019-07-01“…Neural networks can have a complex architecture when different parts of the neural network include different numbers of connections and different neurons.The article develops the ideas laid down by its authors in [7, 8], where a neural network of direct propagation and a way of learning with a teacher have already been used. The model, described below, has been modified due to the authors’ desire to improve it, as well as dictated by the specifics of the housing and utility companies: a list of key indicators has been developed that affect not the financial result, but, consequently, the financial condition of companies in this sector of the Russian economy; the number of input factors characterizing the input sample was increased, each direct factor or group of direct factors was supplemented with an indirect factor; direct and indirect factors explaining the same processes are combined into clusters that influence the corresponding neuron; the number of neurons in the output layer has been expanded, the number of classes has been increased, the data are classified by means of the neural network in more detail; in the course of the program, it is possible to select the period to which the input data (month, quarter, half year, year) belong. …”

Simulation of Soil Freeze-thaw Process and Water Balance in Shrubland Meadow in Shallow Mountain Area of Qilian Mountains
Published 2025-04-01“…Soil water-heat dynamics are pivotal in influencing regional hydrological processes.Understanding the dynamics of soil thermal and moisture changes during freezing and thawing processes is essential for assessing water balance in high-altitude regions.This study utilizes meteorological and soil water-heat observational data from a typical shallow mountainous catchment in the Qilian Mountains to simulate the water-heat dynamics of subalpine shrub meadow soil using the SHAW model, analyzing the changes in water balance during the soil freezing and thawing process.The results indicate that the SHAW model effectively simulates the temporal and vertical variations in soil temperature and moisture in subalpine shrub meadow soils.The findings demonstrates that the Nash-Sutcliffe Efficiency (NSE) for simulated soil temperature at various depths exceeded 0.88, with ae correlation coefficient (R) greater than 0.97and a Root Mean Square Error (RMSE) less than 1.89 ℃.For soil moisture, the correlation coefficient (R) was greater than 0.94, NSE was greater than 0.88.and the RMSE was less than 0.05 m³·m⁻³.Overall, the simulation of soil temperature is more accurate than that of soil moisture, especially in deeper soil layers.The soil freezing and thawing periods, delineated by temperature profiles, revealed a distinct unidirectional freezing and thawing characteristic of the subalpine shrub meadow soil, with the longest duration in the complete freezing period and the shortest in the freezing period.The trends in temperature and moisture across the soil profile exhibit a "U" shape, indicating higher soil temperatures and moisture during the thawing period compared to the freezing period, with significant fluctuations in surface soil moisture and relative stability at deeper layers.The water balance characteristics are significantly varied across different soil freezing and thawing periods.During the freezing period, the precipitation input is 4.28 mm, with the main expenditure of water is deep percolation at 9.06 mm.In the complete freezing period, the precipitation input is 28.69 mm, with the main expenditure of water is surface runoff at 17.90 mm.During the thawing period and the complete thawing period, the precipitation input is 106.29 mm and 207.31 mm respectively, with the major water output through evapotranspiration, where plant transpiration accounted for 78.11% and 71.54% respectively.The soil moisture shows a negative balance during the freezing and complete thawing periods, indicating a net loss of moisture.Conversely, the soil moisture exhibits a positive balance during the complete freezing and thawing periods, signifying a net increase in moisture.This study may provide empirical data and theoretical support for the formation and transformation of water resources in the Qilian Mountain region.…”
