Quantitative Descriptors of Food-web Matrices
A food web customarily describes the qualitative feeding relationships in a community. Descriptors have been used to extract ecologically meaningful information from such data, e.g., the proportion of top species (the proportion of taxa without consumers) or vulnerability (the average number of consumers per taxon). Analyses of collections of food webs based on these properties have revealed re...
متن کاملWeb Matrices: Structural Properties and Generating Combinatorial Identities
In this paper we present new results for the combinatorics of web diagrams and web worlds. These are discrete objects that arise in the physics of calculating scattering amplitudes in non-abelian gauge theories. Web-colouring and web-mixing matrices (collectively known as web matrices) are indexed by ordered pairs of webdiagrams and contain information relating the number of colourings of the f...
متن کاملAnalyzing new features of infected web content in detection of malicious web pages
Recent improvements in web standards and technologies enable the attackers to hide and obfuscate infectious codes with new methods and thus escaping the security filters. In this paper, we study the application of machine learning techniques in detecting malicious web pages. In order to detect malicious web pages, we propose and analyze a novel set of features including HTML, JavaScript (jQuery...
متن کاملA Web Service to Personalise Map Colouring
Offering geospatial data in the World Wide Web (WWW) has developed rapidly in recent years. Today, a lot of data sources are available, many of which provide data by using a Web Map Service (WMS) as interface which is specified by the Open Geospatial Consortium (OGC). In this way, interoperability is achieved: Data and maps are accessible and usable independent of formats, systems, and vendors....
متن کاملA density based clustering approach to distinguish between web robot and human requests to a web server
Today world's dependence on the Internet and the emerging of Web 2.0 applications is significantly increasing the requirement of web robots crawling the sites to support services and technologies. Regardless of the advantages of robots, they may occupy the bandwidth and reduce the performance of web servers. Despite a variety of researches, there is no accurate method for classifying huge data ...
