Item Перша сторінка до розділу “Прикладна та комп’ютерна лінгвістика”(Видавництво Національного університету «Львівська політехніка», 2016)Item Building a smart news annotation system for further evaluation of news validity and reliability of their sources(Видавництво Львівської політехніки, 2013) Shakhovska, Natalia; Berbelyuk, VolodymyrThe article describes the elements of news annotating information systems to further assess the news validity and reliability of their sources. Considers the process of system operation and algorithms that can be used in the implementation of such a system.Item The efficiency of using GIS as subsystem in information model of power generation(Видавництво Львівської політехніки, 2013) Shendryk, Vira; Shulyma, OlhaIn the work were considered the benefits of using GIS in Distributed Energy Generation and tools for creating GIS with the aim to consider existing ways to combine information system with energy efficiency.Item Protection of window glass from acoustic leakage(Видавництво Львівської політехніки, 2013) Lych, Sergij; Rakobovchuk, VolodymyrIn a survey was presented an analysis of the most common glass samples on the Ukrainian market on their protection level against leakage of acoustic information. The glass samples were studied by means of roentgen analysis, and the impact of elemental composition of glass according to a laser beam reflection factor was defined.Item Abstraction 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.Item Authenticity 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.Item Reccurence 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. Trends of Recurrence Rate and Determinism of electroencephalogram recurrence plots are calculated for different time windows. Experiments show that both parameters start to grow approximately 250 seconds in advance of epileptic seizure activity onset for time window of 5 minutes.Item Some aspects of studying of high performance technologies by Moldavian young researchers(Видавництво Львівської політехніки, 2013) Petic, Mircea; Titchiev, Inga; Frinea, Irina; Iliuha, Nicolai; Macari, VeaceslavAim of this article is to present an overview of the project for young researchers - “Systems and Technologies of Distributed Processing of Information and evaluating the effectiveness of their Use” and show which are the goals of project what has been achieved until moment and what are the expected results. The description of available at the Institute of Mathematics and Computer Science HPC infrastructure, adopted methodology and stages of achievment are given. A special compartiment is devoted to workflow Petri nets in modeling of parallel processes. At the end we present a method of image template matching.Item Structural, lexical, and pragmatic features of american immigration acts in historical perspective(Видавництво Львівської політехніки, 2013) Khoma, NataliiaThe article deals with the issue of American immigration act as the linguistic phenomena. The main purpose of the study is to fully analyse structure, lexis and pragmatics of American immigration acts. During the analysis the genre of immigration act was defined. Typology of terms and speech acts was suggested alongside with the dynamics in structure, lexis and pragmatics of immigration acts demonstration.Item Uniform method of operative content management in the electronic content commerce systems(Видавництво Львівської політехніки, 2013) Vysotska, Victoria; Chyrun, Lyubomyr; Chyrun, LiliyaIn the given article content lifecycle model in electronic commerce systems is proposed. The model describes the processes of information resources processing in the electronic content commerce systems and simplifies the content automation management technology. In the given paper the main problems of e-commerce and content function management services are analyzed.
