    The development of a general concept and implementation of a data-storage and analysis system for practice oriented data, one of the subsystems of which is an analytical system for the accumulation and analysis of data from users of social networks, is topical. The development of a general concept and implementation of a data-storage and analysis system for practice oriented data, one of the subsystems of which is an analytical system for the accumulation and analysis of data from users of social networks, is topical. Data that users leave about themselves in social networks can be useful in solving various tasks. The proposed article describes the subject area associated with the collection and storage of data from users of social networks. Proceeding from the subject area, the general architecture of the universal data collection and storage system is proposed, which is based on the client-server architecture. For the server side of the system, a fragment of the data model is provided, which is associated with the accumulation of data from external sources. The framework of the system architecture is described. The developed universal system is based on the information technology of data warehousing, and it has the following aspects: an expandable complex subject area, the integration of stored data that come from various sources, the invariance of stored data in time with mandatory labels, relatively high data stability, the search for necessary trade-off in data redundancy, modularity of individual system units, fl and extensibility of the architecture, high security requirements vulnerable data.The proposed system organizes the process of collecting data and filling the database from external sources. To do this, the system has a module for collecting and converting information from third-party Internet sources and sending them to the database. The system is intended for various users interested in analyzing data of users of social networks.Актуальным представляется разработка общей концепции и реализация системы хранения и анализа данных практико-ориентированной направленности, одной из подсистем которой является аналитическая система накопления и анализа данных пользователей социальных сетей. Данные, которые пользователи оставляют о себе в социальных сетях, могут быть полезны при решении различных задач. В предлагаемой статье описывается предметная область, связанная со сбором и хранением данных пользователей социальных сетей. Исходя из предметной области, предлагается общая архитектура универсальной системы сбора и хранения данных, которая базируется на клиент-серверной архитектуре. Для серверной части системы приводится фрагмент модели данных, которая связана с накоплением данных из внешних источников. Описывается каркас архитектуры системы. Разрабатываемая универсальная система базируется на информационной технологии складирования данных и для нее характерны следующие аспекты: расширяемая комплексная предметная область, интегрированность хранимых данных, которые поступают из различных источников, инвариантность хранимых данных во времени с обязательными метками, относительно высокая стабильность данных, поиск необходимых компромиссов в избыточности данных, модульность отдельных блоков системы, гибкость и расширяемость архитектуры, высокие требования к безопасности хранимых данных.Предлагаемая система организовывает процесс сбора данных и заполнения базы из сторонних источников. Для этого в системе разработан модуль для сбора и преобразования информации из Интернет-источников и отправки их в базу данных. Система предназначена для различных пользователей, заинтересованных в анализе данных пользователей социальных сетей.

    Review of experimental data and modeling of the viscosities of fully liquid slags in the Al2O3-CaO-'FeO'-SiO2 system

    A general model based on the Urbain formalism has been developed, which enables the viscosities of liquid slags to be predicted for all compositions in the Al2O3-CaO-'FeO'-SiO2 system in equilibrium with metallic iron. Available experimental viscosity data have been analyzed and critically reviewed. The Urbain formalism has been modified to include compositional dependent model parameters. Experimental data in unaries, binaries, ternaries, and the quaternary system have been described by the model over the whole compositional and temperature ranges using one set of model parameters. This viscosity model can now be applied to various industrial slag systems

    A quasi-chemical viscosity model for fully liquid slags in the Al2O3-CaO-'FeO'-SiO2 system

    No full text
    A structurally based viscosity model for fully liquid silicate slags has been proposed and applied to the Al2O3-CaO-'FeO'-SiO2 system at metallic iron saturation. The model links the slag viscosity to the internal structure of melts through the concentrations of various anion/cation structural units (SUs). The concentrations of structural units are equivalent to the second nearest neighbor bond concentrations calculated by the quasi-chemical thermodynamic model. This viscosity model describes experimental data over the entire temperature and composition range within the Al2O3-CaO-'FeO'-SiO2 system at metallic iron saturation and can be extended to other industrial slag systems
