Problems of power signal feature modeling for complex fluctuating load by WANG Xuewei, WU Di, YUAN Ruiming, MA Jian, LI Wenwen

“…In order to solve the problems of power signal characteristic analysis, feature extraction, modeling and testing standard of electricity meter encountered in the "three new characteristics" scenario of novel power system construction, this paper points out that the commonly-used load model cannot meet the requirements of testing the dynamic error of electricity meter, the definitions of power signal characteristics and current signal run length affecting electric energy metering are proposed. …”

Cognitive modeling of problems and methods of protecting territories from landslides by Galina V. Gorelova, Dmitry I. Katsko, Alexander I. Katsko

“…The cognitive map made it possible to solve the problem of identifying or match-ing the real landslide process and methods of protecting territories from landslides with their graphical representation in the form of concepts (graph vertices) and cause-and-effect rela-tionships between them (graph edges), which subsequently allows us to move on to formaliza-tion – the construction of mathematical models (Bayesian belief networks, simultaneous equa-tions systems, path analysis models, etc.). …”

DEVELOPMENT OF CITIES IN STAVROPOL KRAI IN THE 1960s: PROBLEMS OF LATE URBANIZATION by E. Pyrkina

“…On the all-Russian background of the mid-twentieth century, the cities of Stavropol were poorly urbanized, despite the rapid growth of the urban population and the high concentration of new industrial construction in them. At the same time, albeit slowly, with great dificulty, the process of changing the economic activities of the townspeople began - the proportion of the population engaged in management, culture, and maintenance increased, and signs of a shift to industrial work appeared. …”
