Abstract: The internet, as a unique medium of communication and information, converges different media forms into networks and simultaneously, different modes of communications. This creates difficulty in choosing a theory when carrying out studies on the socio-economic, psychological and political basis of the internet. Selecting a theory that appropriately suit such studies will depend on the theory’s potential to offer a view of a very powerful mass medium that ties its power to the audience members’ dependency on the medium and its contents. This paper, enumerates several reasons why the Dependency Theory of mass communication is most aptly suited for Internet/Web studies. It also explaines the stand of Defleur and Ball-Rokeach who offered this theory and some insights into some studies and opinions of media experts who support the application of this theory on internet studies.

Abstract: Nowadays more and more applications require a mobile robot able to operate autonomously in an outdoor environment. The accuracy and precision of mapping systems for the working environment is particularly important for the management, control and efficiency of the activity of the mobile robot. For these reasons, mapping systems must be consistent and efficient, and capable to represent in real-time the surroundings, thus allowing the robot, equipped with a system of autonomous movement, the exploration of unknown environments. Here we present a new Web GIS platform able to track the navigation of mobile robots on a georeferenced cartographic data and to assign possible paths or waypoints. The WebGIS platform has been developed using only free and open source software and has been customized with useful tools for the management of the navigation of mobile robots.
