Shchogoleva","doi":"10.15407/csc.2021.04.013","DOIUrl":"https://doi.org/10.15407/csc.2021.04.013","url":null,"abstract":"Introduction. Digitization of legislation is an important area today, which is identified by the government as a priority. Creating digital legal documents and verifying them for compliance with the law is a necessary task in all areas of jurisprudence. This sets the task of automatic formalizing a legal document created as an arbitrary text in natural language. Purpose. Preparing a document for storage in digital format for further processing may require prior work with an original text. When using automatic means of linguistic analysis of the texts submitted in natural language, in particular, legal, which processes the text in sentences (working up the text sequentially sentence by sentence), problems of local and global nature arise. The problem of local nature is created, in particular, by the presence in the text of the sentences, which due to their considerable length are difficult to process (with the help of one or another tool of text analysis). The problem of a global nature arises when the semantic connection between the components of different sentences should be taken into account during the automatic processing of the text. The purpose of this work is to develop means for overcoming these problems. Results. A model for structuring long sentences containing enumerations as well as a method for eliminating the synonymy of object names referred to in the text, which is intended for automatic analysis, has been developed. Conclusion. Marking up sentences containing enumerations is useful, especially when the text is intended for analysis using a procedure that processes the text sentence by sentence. Structuring a sentence with an enumeration enables, on the one hand, to prepare the sentence for processing in parts, and on the other hand, not to lose the integrity of the sentence when processing in parts. In the method of eliminating the synonymy of names proposed in this paper, both the step of identifying the names of objects and the step of revealing the identity of names requires semantic analysis. To control the correctness of these steps, Oracle was introduced to improve the reliability of the result.","PeriodicalId":33554,"journal":{"name":"Control Systems and Computers","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41515901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The linguistic approach, based on the transition from the observed cyclic signal to a sequence of symbols (codeword), which characterize the dynamics of indicators from cycle to cycle, makes it possible to use the procedures of mathematical linguistics to increase the reliability of decisions. The purpose of the article is to expand the diagnostic capabilities of the linguistic approach to the analysis and interpretation of electrocardiograms (ECG). Methods. Each ECG cycle is encoded with one of four symbols characterizing changes in two indicators: traditional (cycle duration) and original (symmetry of the repolarization area). Results. Based on the processing of real clinical data of verified patients and healthy volunteers, standards of patients with chronic coronary artery disease (СAD) and healthy patients. The standards are developed using computational procedures of mathematical linguistics – the Levenshtein distance, which is the minimum number of editing operations (insertion, deletion and replacement of a character), ensuring the transition from one word to another and the frequency of occurrence of substrings in the analyzed word. On the basis of these procedures, decision rules that have been developed allow making diagnostic decisions based on the Levenshtein distance to the standards and the frequency of occurrence of one-, two- and three-symbol patterns in code words. It was found that the combination of these two methods expands the diagnostic capabilities of the linguistic approach to the analysis and interpretation of the ECG. Conclusions. It has been shown that using of the developed decision rules makes it possible to increase the sensitivity and specificity of diagnostics even in cases when the ECG does not show traditional electrocardiological signs of myocardial ischemia.","PeriodicalId":33554,"journal":{"name":"Control Systems and Computers","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46869870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The control unit coordinating interaction of all other blocks of a digital system is one of the central blocks and is a sequential circuit. As a rule, when synthesizing control unit circuits, the problem arises of reducing hardware costs. Methods for solving this problem depend on features of both the architecture of the control unit and the elemental basis. Purpose. The main goal of this work is to reduce hardware costs and power consumption of control units of digital systems by taking into account features of the element base of the control unit and rational organization of addressing microinstructions. FPGA (field-programmable logic array) microcircuits, widely used for the implementation of modern digital systems, were chosen as an elementary basis. Methods. Methods of set theory, synthesis of automata, and software modeling as well as the library of standard automata and FPGA Virtex-7 from Xilinx were used for assessment the effectiveness of solving the problem. Results. The paper proposes a method for optimizing the circuit of the microinstruction addressing unit based on splitting the set of outputs of elementary linear operator circuits, which is based on the idea of double coding of states. The proposed method, under certain conditions, makes it possible to reduce the number of levels in the microinstruction addressing circuit to two. Conclusion. Studies have shown that double coding of states can increase performance, reduce hardware costs (the number of LUTs and their interconnections) and power consumption in Mealy’s circuitry. Based on these results, it can be expected that, with the number of conditions exceeding the number of LUT inputs, the proposed approach will improve the characteristics of the composition microprogram control unit in comparison with the equivalent control unit U1.","PeriodicalId":33554,"journal":{"name":"Control Systems and Computers","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45520841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The digital economy, being customer-oriented, highlights the provision of high-quality services and processes. The successful solution of this problem depends on many factors, among which the assessment of the quality of the service of logistics services by the transport system plays an important role. Purpose. For the sustainable development of the transport and logistics system, it is necessary to develop a concept for ensuring the assessment of the quality of logistics services based on a qualimetric approach to obtain a synergistic effect of the system’s functioning Methodology. The methodology and problems of qualimetry concentrate on a comprehensive and quantitative assessment of the quality of objects of any nature, including logistics services. To solve the problem of assessing the synergistic effect of the qualitative functioning of the transport and logistics system, a nonparametric DEA (Data Envelopment Analysis) method is proposed, which is a highly intelligent method for analyzing the functioning environment due to the fact that its methodology is based on the intelligent technology of benchmarking – comparative analysis based on reference indicators (standards) Results. The transport and logistics system, as an ordered set of elements with certain connections, has special systemic properties that are not inherent in individual elements, but allow for a synergistic effect in the process of functioning. The effect of logistic synergy arises in the process of mutual strengthening of relations between the internal and external environment at the level of input and output material and information flows. Quality management of logistics services is based on the provision of operational information about the quality of logistics services and timely management decisions to ensure this quality. In accordance with the principles of the standards, product quality management is aimed at ensuring customer satisfaction and continuously improving the quality of logistics services. Conclusions. To find a general assessment of the efficiency of the functioning of the transport and logistics system based on the DEA method, the following were developed: a model for assessing the effectiveness of input (i.e., use of resources), oriented to the input, and a model for assessing the efficiency of an output (i.e. logistic system), that is output-oriented. The model developed on the basis of the DEA method for assessing the efficiency of the functioning of the transport and logistics system allows to evaluate it as a stable system in a certain period of time, using the normative quality of the performed logistics services.","PeriodicalId":33554,"journal":{"name":"Control Systems and Computers","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41739125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A characteristic feature of the modern agricultural sector is the use of advisory that provides the implementation of modern technologies into the production process. We analyze the specifics of existing advisory systems, their goals, main activities, and problems. This analysis causes expediency of documentation and validation of informal and non-formal outcomes of learning typical for agriculture and their processing by knowledge-oriented services based on modern Semantic Web technologies and resources. Purpose. This work is intended for the integration of labour and education markets and is aimed at semantization of agricultural advisory services for the expansion of advisory system functionality with the help of validation of outcomes of non-formal and informal learning of potential employees. Processing of semantics is based on the use of knowledge about agriculture subjects from internal and external ontologies by advisory intelligent applications. Such processing requires the creation of a relevant formal model that describes all main objects and subjects of agro-advisory activities, development of formalization methods for model components and defining of matching criteria based on internal and external ontologies. Software realization of proposed solution by AdvisOnt system is aimed at demonstration of its efficiency for practical agro-advisory tasks and advantages of semantic approach. Methods. In this work, we use methods of mathematical modeling, elements of ontological analysis and logical inference. Results. We propose an advisory system AdvisOnt that analyses the outcomes of non-formal and informal learning and ensures their validation for more efficient matching of information about potential employees, employers and agricultural educational resources. AdvisOnt is based on ontological representation of this knowledge formalized by competencies, vacancies, training courses, user profiles, etc. The system is aimed to generate recommendations for employment or further learning of necessary competencies by matching these objects. External knowledge bases are used for semantic formalization of vacancies and resumes for their more pertinent matching with the help of agricultural domain knowledge and competence classifications. AdvisOnt users receive recommendations on employment and about training courses that provide advisable competencies. Conclusion. Sustainable development of agro-industrial production needs rapid dissemination of agricultural knowledge and information, mobility and continuous training of agricultural professionals provided by advisory systems. We suggest how using ontological knowledge for advisory services allows to expand the possibilities of counseling.
