Web Pages Content Analysis Using Browser-Based Volunteer Computing

Existing solutions to the problem of finding valuable information on the Websuffers from several limitations like simplified query languages, out-of-date in-formation or arbitrary results sorting. In this paper a different approach to thisproblem is described. It is based on the idea of distributed processing of Webpages content. To provide sufficient performance, the idea of browser-basedvolunteer computing is utilized, which requires the implementation of text pro-cessing algorithms in JavaScript. In this paper the architecture of Web pagescontent analysis system is presented, details concerning the implementation ofthe system and the text processing algorithms are described and test resultsare provided

Volunteer Computing Simulation Using Repast And Mason

Volunteer environments usually consist of a large number of computing nodes,with highly dynamic characteristics, therefore reliable models for a planning ofthe whole computing are highly desired. An easy to implement approach to mo-delling and simulation of such environments may employ agent-based universalsimulation frameworks, such as RePast or MASON. In the course of the paperthe above-mentioned simulation frameworks are adapted to support simulationof volunteer computing. After giving implementation details, selected resultsconcerning computing time and speedup are given and are compared with theones obtained from an actual volunteer environment

Anti-Crisis Management of City Traffic Using Agent-Based Approach

The paper presents a multi-agent system for modelling and optimising city traffic. Our attention is focused on the prevention of crisis situations and detection of anomalies. Analysed critical situations include traffic jams, whereas an anomaly is when there is a decrease in average vehicle velocity in the whole city or its part. The methods of crisis situation prevention are based on the choice and configuration of the appropriate algorithms of city light management or on modification of intersection and road network topologies
