FINDING AND RANKING KNOWLEDGE ON THE SEMANTIC WEB
DescriptionThe basis of Semantic Web technology is the possibility of joint construction of ontology and the formation of the dictionary without centralized control. All the information and the knowledge encoded in the ontology as semantic web-terms and the semantic web-documents. Swoogle helps software agents and knowledge engineers find Semantic Web knowledge encoded in RDF and OWL documents on the Web. Navigating such a Semantic Web on the Web is difficult due to the paucity of explicit hyperlinks beyond the namespaces in URIrefs and the few interdocument links like rdfs:seeAlso and owl:imports. In order to solve this issue, this paper proposes a novel Semantic Web navigation model providing additional navigation paths through Swoogle’s search services such as the Ontology Dictionary. Using this model, we have developed algorithms for ranking of Semantic Web objects at three levels of granularity: documents, terms and RDF graphs. The article focuses on the ranking at the document level, based on a rational search model, which emits the agent's behavior when navigating at the document level, and ranking on level terms, the value of which is determined by the number of their references in all documents

Description
One of the key areas of interdisciplinary research is to ensure public safety. In order to solve a number of problems within this area we can effectively use information technology and, in particular, an automated pattern recognition technology and identification of objects on digital images. There are addition problems in objects identifying process besides eliminating the influence of ambient light, angle, items of clothing and headgear. To ensure the applicability of the recognition approach to public security issues it must meet requirements of the high processing speed, the replenishment capabilities onthe-fly list of known images, and the low computational complexity of algorithms. The article deals with the main approaches to the recognition and identification of objects on digital images based on statistical approaches, as well as neural network models. We have allocate their basic features and principles, provided a brief description of each method. Consideration has been made in terms of the application for the problems of public safety, in which there is importance of the speed of the identification of the object, the ability of quickly learning for the system to accept new images and simultaneously process a plurality of input images. The analysis of the existing approaches has shown that none of them satisfy at least one or several needs, which are defined by domain problems of public safety

MODELING NEURAL INTERACTIONS WITH THE USE OF CELLULAR AUTOMATION
DescriptionThis article considers the organization of neuralnetwork interactions based on models of cellular automata. These models are focused on improving the efficiency of the iterative processes of functioning of neural networks and their learning. The models considered in this article are presented in the form of two-level hierarchical structures. Models of the lower level are defined as "cellular neural element". They are based on formal descriptions of the dynamic neurons with the additional insertion of the state functions and the special procedures of formation of the specified function. Also, we have added special methods for forming patterns of activation functions. The conception of developed models is based on the use of the theory of graphs, theory of neural networks and the mechanism of cellular automata. These models will be used as the basis for software modeling

CLINICAL AND MORPHOLOGICAL FACTORS AND PREDICTION PARAMETERS OF CELL CYCLE IN ESOPHAGEAL CANCER
DescriptionThe aim of the study is to compare the traditional clinicopathologic factors and prognosis of cell cycle parameters, such as ploidy, cell cycle kinetics, as well as the study of DNA content in the tumor tissue of patients with esophageal cancer. Cancer of the esophagus - a very aggressive malignant disease, most commonly manifested impaired swallowing. As a rule, this type of cancer pathology is characterized by unfavorable outcome. Ploidy and cell proliferation activity, defined by the content of the DNA of the tumor - synthesizing cells are one of the important indicators of the growth rate of malignancy and prognosis. The study was performed on tumor tissue fragments of the 30 patients operated on for cancer of the esophagus. DNA study - conducted in the open cell material aftercare. DNA cell content was determined by flow cytometry BD FACSCanto II. By studying the DNA-cytometric parameters, we found the prevalence of aneuploid tumors in 66.7%. It was shown that DNAcytometric parameters are independent of gender. Major weight of diploid and aneuploid cell tumors of the esophagus was in G0 / 1 phase of the cell cycle. Comparative analysis of DNA - cytometric parameters and the degree of differentiation of esophageal tumor revealed a prevalence of aneuploid tumors in all the test cases. content distribution pattern of tumor cells was found in the G0 / G1-, G2 + M -, S - phase of the cell cycle at different stages of the disease
