Computers with fast processing units and large amounts of memory allow for practical applications of time consuming and resource intensive algorithms, both for spatial analysis as well as visualization of large-volume data such as high resolution raster images, DTM and vector data. However, most Web-based geographic information systems are used for presentation of static data, while the area of dynamic and semi-dynamic data visualization has been mostly neglected. Novel applications of known devices and models such as synthetic aperture radar and oil spill simulations require interactive data presentation, which up until now has been mostly realized using standalone applications or thick Web clients. This paper describes a number of Web-based GIS technologies for presentation of semi-dynamic geographic information retrieved from many different sources. It also describes the possibilities these technologies provide for publishing interactive geospatial data such as oil spill spread animation overlaid on background data (eg. terrain elevation data, satellite imagery) and presented in a geographic context. Web-GIS technologies like ESRI ArcIMS (Arc Internet map server) and open source geoserver with OpenLayers client library were compared during the research. The paper presents their corresponding capabilities, interactive geographic information presentation efficiency as well as general performance when serving considerable amounts of data.","PeriodicalId":247264,"journal":{"name":"2008 1st International Conference on Information Technology","volume":"17 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113975145","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}

Programs which fulfill this functionality are called file integrity checkers. This paper concerns modern approach to file system integrity checking. It reviews architecture of popular systems that are widely used in production environment as well as scientific projects, which not only detect intruders but also take actions to stop their activity. The concept and architecture of ICAR system (integrity checking and restoring system), which we are developing, will be presented. The ICAR System not only covers functionality of integrity checkers but also automatically restores files, which were modified by the intruder. ICAR has been designed as kernel module of the operating system and it uses read-only devices to store data. The article can prove useful to the operating systems users, that are interested in securing their data and system configuration.","PeriodicalId":247264,"journal":{"name":"2008 1st International Conference on Information Technology","volume":"11 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":"121849189","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}

In this article we describe the Relative Fairness Bound measure which is often used to evaluate fairness of different packet scheduling algorithms found in communication networks. We examine this measure using the apportionment theory which is used to analyze the apportionment of seats in a parliament. The main result of our analysis is that there exists no practical algorithm optimizing the RFB measure. We show that any algorithm optimizing the relative fairness bound must use potentially huge buffer to collect incoming packets that have to be scheduled. We show that a method optimizing the RFB measure is neither house monotone nor population monotone.","PeriodicalId":247264,"journal":{"name":"2008 1st International Conference on Information Technology","volume":"2 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":"133179100","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}

In the general case a problem of determining the chromatic number is NP-hard, thus any graph invariants that can be used to bound it are of great interest. Within this paper we discuss the properties of the invariants originating in the notion of a potential function. We study their interdependencies and the relationships to the classical Welsh-Powell and Szekeres-Wilf numbers. We also present the results of experimental comparison of two known sequential algorithms to the algorithms that use orderings of vertices with respect to their potentials.","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":"128241616","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}
