This paper presents a modular approach to discover process models for multi-agent systems from event logs. System event logs are filtered according to individual agent behavior. We discover workflow nets for each agent using existing process discovery algorithms. We consider asynchronous interactions among agents. Given a specification of an interaction protocol, we propose a general scheme of workflow net composition. By using morphisms, we prove that this composition preserves soundness of components. A quality evaluation shows the increase in the precision of models discovered by the proposed approach.
Studying of color palette in watercolor painting is being reported in the following article. To create an expressive image, out of the real world colors the artist chooses those that match his thoughts, feelings and artistic solution of a painting. Examples of tasks are being offered which help with the studying of color palette and auspiciously influence development of creative abilities, creative thinking of students, pupils and scholars.
The ultimate goal of this study is to demonstrate the legitimacy of “Nekrasov’s byronism” as a research topic. For this purpose we are trying to prove that Byron’s poetry influenced the poetry of Nekrasov. In particular, Byron’s poems partially formed the structure of the Nekrasov’s poem “Who is Happy in Russia” (1863–1876). Byron’s poems are inclined to dramatic composition, separate scenes and include songs. “Komu na Rusi zhit’ khorosho” also tends to drama, consists of a chain of scenes, monologues, dialogues and contains inserts in the form of songs. Poet Grisha Dobrosklonov, one of the main Nekrasov’s poem characters, corresponds to Byronic romantic hero. Byron’s influence on the poetry of Nekrasov is confirmed by the fact that among his first books Nekrasov called the tragedy of Valerian Olin “The Corsaire”, the translation of the Byron’s poem. The ballet “The Corsaire” made after the poem by Lord Byron, twice delivered in St. Petersburg at the turn of the 1850s and 1860s, as well as increasing public interest in the figure of British classics could also revived Nekrasov’s long-standing impressions at that time.

Despite all the advantages brought by service-oriented architecture (SOA), experts argue that SOA introduces more complexity into information systems rather than resolving it. The problem of service integration challenges modern companies taking the risk of implementing SOA. One of important aspects of this problem relates to dynamic service composition, which has to take into account many types of information and restrictions existing in each enterprise. Moreover, all the changes in business logic should also be promptly reflected. This chapter proposes the approach to solution of the stated problem based on such concepts as model-driven architecture (MDA), ontology modelling and logical analysis. The approach consists of several steps of modelling and finite scope logical analysis for automated translation of business processes into the sequence of service invocations. Formal language of relational logic is proposed as a key element of the proposed approach which is responsible for logical analysis and service workflow generation. We present a logical theory to automatically specialize generic orchestration templates which are close to semantic specification of abstract services in OWL-S. The developed logical theory is described formally in terms of Relational Logic. Our approach is implemented and tested using MIT Alloy Analyzer software.
Plein-air in additional education studio organization is being discussed in the article. As a part of estetic students' education, open-air represents drawing and painting outside in open-air. Purpose of open-air working is to fasten and broaden knowledge and experience received during academic year, to develop abilities of its creative application in open space natural illumination conditions. Different activities are being described: drawing (doodle, sketch, long-tirmed drawing) and painting (short-termed and long-termed etude).
