Classification of roles played by the actors can be very informative because it gives us the complete overview of the network allowing for understanding how the network is organized and how it is going to behave in front of certain external or internal events. In the paper we present how this task can be accomplished with support of OWL-based ontology and related tools. As a sample social structure we use a network of e-mail users.","PeriodicalId":247264,"journal":{"name":"2008 1st International Conference on Information Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122008686","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}

Basic requirement is fast (under 50 ms) determination of the commune of the subscriber. To obtain as accurate information as possible aggregation of several methods was proposed: using a database of locations of IP ranges created by specialized companies, traceroute and using history of the user locations to assume his current one. It is also explained how the concept described above was implemented and run on a testing platform along with the results of its operation. In the ending part of the article the directions of development were described.","PeriodicalId":247264,"journal":{"name":"2008 1st International Conference on Information Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129235230","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}

However, produced sequences are much shorter and there are many more of them, which indicate that the problem is harder. Presented algorithm was created to process data from 454 sequencing method.

Geoobjects are used to model discrete entities such as districts or roads and geofields for continuous phenomena such as air pollution or temperature over a given region. The term geofield query denotes a query regarding geofields. This paper addresses geofield query processing by introducing: (a) PNR representation - relational representation of geofields and geoobjects based on Peano N space-filling curve and relation-valued attributes, (b) Peano algebra - a set of operations extending relational algebra with operations for processing geofields and geoobjects in PNR representation, and (c) geofield queries optimization rules. Presented Peano algebra and optimization rules made it possible to evaluate geofield queries much faster than in classical raster representation.","PeriodicalId":247264,"journal":{"name":"2008 1st International Conference on Information Technology","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122528744","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}

Let us call S a list assignment for G. We look for a legal graph coloring f such that for every vertex v isin V we have f(v) isin S(v). A trade from a vertex u to v means that we remove color c from S(u) and add it to S(v). In the trading model we ask how many trades are required in order to obtain a list assignment that has a list coloring. So (G, S) is p-tradeable if this can be done in p or fewer trades. We show a polynomial algorithm for determining the minimal p for complete graphs. An analogous problem for trees is NP-hard. However, it is polynomial for partial k-trees with fixed k and fixed total number of colors.","PeriodicalId":247264,"journal":{"name":"2008 1st International Conference on Information Technology","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126705147","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}

Several approaches and techniques of measurements are available for marine environment monitoring including direct sampling, airborne and satellite imagery and underwater acoustics. The huge development in the information technology has provided the possibilities for much faster and more efficient access to survey data, allowing their remote, nearly real-time management, processing and visualisation. The proposed GIS is able to integrate many different types of marine pollution survey data, especially those acquired by various acoustic sensors like Multibeam Sonar Systems (MBSS), echosounder and Side Scan Sonars (SSS). It also supports instantaneous 2D and 3D visualisation in the form of thematic layers that can be overlaid. The system utilises the ArcSDE application server that facilitates storing and managing spatial data (raster, vector, and survey) in a database and ArcGIS Engine GlobeControl and MapControl components for georeferenced presentation of various objects. The set of geoprocessing and spatial analysis methods can be used in order to retrieve relevant information and analysis results.","PeriodicalId":247264,"journal":{"name":"2008 1st International Conference on Information Technology","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113932456","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}
