Introduction In 1987, the need to strive towards development aimed at making it possible to satisfy the present needs without compromising the needs of future generations is generally acknowledged. The Rio Earth Summit in 1992 propagated Agenda 211, whi ...
Our component-based parametrisable font system is a newly developed font description and reproduction technology. It incorporates for each basic character shape a software method responsible for the synthesis of an instance of that character. A given font ...
This paper provides an asymptotic performance evaluation of network-based or multilateral positioning systems, where the times and/or angles of arrival of the signals traveling from a mobile station (MS) to a set of fixed stations (FSs) are used to estimat ...

A life cycle assessment was carried out based on a detailed life cycle inventory for a typical GSM 900 mobile phone network and related End of Life (EOL) treatment infrastructure. The environmental relevance of the three life cycle phases: production, use ...
So far, cellular networks have been operated in "private" frequency bands. But recently, several researchers and legislators have argued in favor of a more flexible and more efficient management of the spectrum, leading to the possible coexistence of sever ...
This document develops an analysis of the performance of a VoIP application over W-CDMA HSUPA. It starts by describing fundamental issues about VoIP. Then, it investigates several limiting factors of HSUPA voice capacity, i.e. HSUPA control channel overhea ...
Naouel Ben Salem, Levente Buttyan, Jean-Pierre Hubaux and Markus Jakobsson abstract: In multi-hop cellular networks, the existence of a communication link between the mobile station and the base station is not required: a mobile station that has no direct ...

With the development of object identification technology object tagging becomes more and more common. In this work we analyze how recycling processes can benefit from deployment of passive RFID tags and discuss how spreading small electronic chips in the e ...
