    Application of mashup technology for dynamic integration of semi-structured data
    (Видавництво Львівської політехніки, 2013) Kushniretska, Irina; Berko, Andriy
    The usage mashup-technology for the dynamic integration of semi-structured data has been considered in this paper. Architecture of web-mashup, which consists of the three parts has been described. The process of the creation the mashup-service on data level, on process level and on presentation level has been presented. Four specific search strategies that use different kinds of information for query ranking and selection have been proposed.

    Modeling of sewer networks by means of directed graphs
    (Lviv Politechnic Publishing House, 2017-03-21) Berko, Andriy; Zhuk, Volodymyr; Sereda, Igor; Lviv Polytechnic National University
    The paper presents an analysis of the known theoretical models of drainage network of the city as directed graphs of different types. It is proved that ringing sewer networks increases reliability of their work and improves maneuverability and regulation of drainage system as a whole. A theory of solving the optimization problem “capacity – economic efficiency” was proposed to design optimization schemes for sewage system, using the straightdual algorithmproposed by Saharovych.
