Machine learning for text classification is the cornerstone of document categorization, news filtering, document routing, and personalization. In text domains, effective feature selection is essential to make the learning task efficient and more accurate. This paper presents an empirical comparison

developed and installed a system for use by visitors to Lancaster. The system combines mobile computing technologies with a wireless infrastructure to present city visitors with information tailored to both their personal and environmental contexts. In this paper we present an evaluation of GUIDE, focusing

Attempts to generalize the Internet's point-to-point communication abstraction to provide services like multicast, anycast, and mobility have faced challenging technical problems and deployment barriers. To ease the deployment of such services, this paper proposes an overlay-based Internet Indirection Infrastructure (i3) that offers a rendezvous-based communication abstraction. Instead of explicitly sending a packet to a destination, each packet is associated with an identifier; this identifier is then used by the receiver to obtain delivery of the packet. This level of indirection decouples the act of sending from the act of receiving, and allows i3 to efficiently support a wide variety of fundamental communication services. To demonstrate the feasibility of this approach, we have designed and built a prototype based on the Chord lookup protocol.

We present an art installation entitled “WAP kitchen”, presented at the 7th International Festival of Computer Arts in Maribor, May 2001. The project is a result of collaboration of the academic sculptor Duˇsan Bučar from the Academy of Fine Arts with students and educators from the Faculty

Understanding usage patterns in wireless local-area networks (WLANs) is critical for those who develop, deploy, and manage WLAN technology, as well as those who develop systems and application software for wireless networks. This paper presents results from the largest and most comprehensive trace

popular. Access to the World Wide Web from such devices is usually done through Wireless Application Protocol (WAP). There is a set of concerns over how secure and usable WAP is as a technology, and whether it is robust enough to implement mobile commerce applications, and other applications

The Wireless Application Protocol (WAP) is rapidly growing to be the de facto standard for small wireless devices and mobile devices--mobile phones, personal digital assistants (PDAs), pagers-- to connect to Internet as part of “Mobile Computing Revolution”. Most of these wireless and mobile

. The studies of the protocol include an overview of the architecture, a description of the different layers of the protocol stack and an introduction to how the security layer works. Some advantages with WAP as well as alternatives to the protocol within the wireless domain are also included. For the future

This master thesis will give a brief introduction to WAP technology. The aim of this research was to investigate how to deliver alarms, which show faultsoccuring in the a telecommunication system and link between a WAP device. By studying documents, white papers and seeking knowledge from employees

Abstract: The paper presents issues and architectures for mobile applications and GSM infrastructure. The paper shows the redesign of the solution for avoiding denial of service from WAP applications using WIM features. The first section contains the structure of GSM network from voice and data
