The large amount of information that is spread over the Internet is an important resource for all people but also introduces some issues that must be faced. The dynamism and the uncertainty of the Internet, along with the heterogeneity of the sources of information are the two main challanges for the today’s technologies. This paper proposes an approach based on mobile agents integrated in an i...

An increasing amount of information is available from mobile devices. We consider the problem of retrieving data from mobile sources in an information-centric network architecture called Named Data Networking. We propose an approach in which indirection points locally map requests for persistent data names to requests for temporary location names that reflects the sources’ current network attac...

The goal of this paper is to examine randomness sources available in current mobile phones or other mobile devices. We identify potential sources of randomness and perform an analysis focused on the camera and the microphone input noise as promising sources of randomness. We also perform statistical tests and analyse quality of these sources of randomness including estimation of entropy in the ...

In our paper we study practical aspects of random and pseudorandom number generation in mobile environments. We examine and analyze several sources of randomness available in current mobile phones and other mobile devices at the application level. We identify good physical sources of randomness that are capable of generating data with high entropy in reasonable time and we investigate some rele...

We present the user-centered, iterative design of Mobile Facets, a mobile application for the faceted search and exploration of a large, multidimensional data set of social media on a touchscreen mobile phone. Mobile Facets provides retrieval of resources such as places, persons, organizations, and events from an integration of different open social media sources and professional content source...

Physicochemical fundamentals have been developed for the basic design solutions and fabrication technologies of prospective electrolytic power cells with a reusable cell capacity 350–500 W·h/kg at first stage 1000 second stage. Along conventional chemical current sources ionistors, there are emerging high-performance supercapacitor structures thin dielectric in double electric layer hybrid capa...
