ItemAbstraction of synchronous computational model for parallel graph processing(Видавництво Львівської політехніки, 2013) Romaniuk, Oleksandr; Koroteeva, TetyanaThe analysis of current approaches to the development of algorithms for parallel and distributed computing on data graphs. The proposed technique facilitates the writing of parallel algorithms based on graphs by usage of the Actor and the Valiant's Bulk-Synchronous Parallel models. This approach differs by determinism of algorithms, by resilience to different faults and by higher level of abstraction that makes a developer free from implementation details introduced by parallel and concurrent programming primitives. ItemAuthenticity of digital images(Видавництво Львівської політехніки, 2013) Hanzlik, Lucjan; Wodo, WojciechCopyrights are a big issue these days, it is extremely easy to loose our intellectual property (in sense of digital images) and thus money, moreover it is hard to proof our rights in the court. Our digital pictures must be protected in such a manner that it should be easy to proof we are the legitimate owner of the image and it should be computationally hard to forge such proof. We present a sketch of a new solution for copyright protection of digital images using chameleon hash functions, signatures and steganography. It is an extension of previous work in this field. We introduce a probabilistic similarity method into our scheme, which convince the verifier at certain level about the owner of the picture. ItemReccurence plots parameters during epileptic seizure patterns onset(Видавництво Львівської політехніки, 2013) Popov, Anton; Topikha, OleksandrThe purpose of the paper is to investigate the applicability of recurrence plots paremeters for early detection of epileptic seizures.

The method implements the information resources processing in electronic content commerce systems and automation technology simplifies the commercial content formation. In the given article the main problems of electronic content commerce and functional services of commercial content forming are analyzed. The proposed method gives an opportunity to create an instrument of information resources processing and to implement the module of content forming. ItemLife cycle of the electronic encyclopedia as the information system(Видавництво Львівської політехніки, 2013) Zhezhnych, Pavlo; Hirnyak, MariyaThe paper dwells on the integral aspect of the electronic encyclopedia, namely its life cycle. There is a generalized system of the electronic encyclopedia formation in this article. It reveals the essence of the each life cycle stage. It is justified the choice of knowledge extraction from open texts for the encyclopedic conten formation. ItemImage classification and retrieval by color concentration features(Видавництво Львівської політехніки, 2013) Melnyk, Roman; Hryha, ІvanThe method for distributed features of visual pattern extracted from intensity fragments and segments is considered.

ItemVerbalization of communicative strategies and tactics in the speech genre of parliamentary debate (based on debates in the House of Commons on March 25, 2013)(Видавництво Львівської політехніки, 2013) Artym, KhrystynaThe article focuses on communication between members of parliament, viewed as a strategic process. It provides a comprehensive research into lingual-and-pragmatic features of parliamentary debate as a specific genre of political discourse. The argumentative strategy is regarded as the central component of the communicative model of debate. It is implemented through a number of tactics. Communicative moves, linguistic and speech means of their realization are analyzed. The research suggests theoretical and practical perspectives and directions for future research, while the comprehensive classification of communicative strategies and tactics still does not exist.

ItemThe representation of high order Markov process through equivalent first order process(Видавництво Львівської політехніки, 2013) Yakovyna, Vitaliy; Nytrebych, Oksana; Fedasyuk, DmytroThe expanded transition probability matrix with size of S Sn S is used to represent n-order Markov process, which consists of S components, through first order process. With growth of process order the matrix size increases rapidly and a lot of resources are needed to store it, although many of its elements are zero. In this paper we propose to split states of Markov processes to "fictitious" depending on the model order, which can significantly reduce the size of the transition probability matrix.

This allows to analyse the software reliability at the early lifecycle stages. ItemEnglish poetry analysis with the assistance of database(Видавництво Львівської політехніки, 2013) Bondaruk, OlenaThe article illustrates the role of database application in linguistic researches, namely in master theses at the applied linguistics department of Lviv National Polytechnic University. The novelty of the analysis lies in exploring the linguistic phenomena using the database management systems. The analysis is exemplified by the exploration of database that is used to resolve the linguistic issues and to optimize the examination of lexical features of English poetry in the late 16th - early 17th centuries.
