1. We examined mechanisms of coexistence between two congeneric species of frugivorous primates, the blue monkey (Cercopithecus mitis) and the red-tailed monkey (C. ascanius). 2. We used giving-up densities (the amount of food which animals leave in a patch) in fruit trees to measure foraging efficiency and to evaluate possible mechanisms of coexistence.(More)
In the last few years, we saw the emergence of Voice-Over-IP (VoIP) protocols to enable low-cost telephony services. While VoIP providers are rapidly growing market share against Public Switched Telephone Network (PSTN), these technologies are lacking mobile support. We believe that Mobile Ad Hoc Networks (MANETs) may offer a good platform for the fast(More)
MANET networks are transitory, poorly regulated and essentially local in nature. Such environments have need for Information Assurance (IA) services, but the lack of regulation, the limited reach-back connectivity, and the ad hoc nature of the networks make supplying these services difficult. MANET IA services should supply subscriber confidentiality, data(More)
—The focus of this paper is on the minimum cost resource provisioning and nodal equipment location (PROVLOC) problem for Wide Area Networks (OWANs), i.e., optical networks that cover broad areas. Minimizing the cost means minimizing the network capital and operational expenditures throughout the dimensioning of the nodal equipment, and the location of(More)
