In this paper we provide an arc-path formulation for the problem of locating and sizing wavelength division multiplexing (WDM) and optical cross-connect (OXC) equipment in a %ber optic network. The problem is heuristically solved by limiting the number of paths for each demand and applying CPLEX to the resulting formulation. The results obtained are then compared to those given by a metaheurist...

This paper investigates the role of pitch accent information in spoken-word recognition in listeners in Fukushima, Japan, whose dialect is accentless. Previous research revealed that accentless listeners were less sensitive to pitch accent than Tokyo Japanese listeners. The present study asked whether middle-aged listeners’ use of accent information would differ from that of young listeners. 40...

The Telecommunication Sector of the International Telecommunication Union (ITU-T) has developed a set of standards for multimedia conferencing over packet-based networks. These standards are aggregated under a standard umbrella termed Recommendation H.323. Recommendation H.323 describes terminals, equipment, and services for multimedia communication over networks such as the Internet. H.323 ter...

The reduction of the energy consumptions of a Telecommunication Power System represents one of the critical factors of the telecommunication technologies, both to allow a sizeable saving of economic resources and to realize "sustainable" development actions. The consumption of about one hundred base stations for mobile phones were monitored for a total of over one thousand days, in order to stu...
