Research presented in this paper uses the Network Simulator, ns2, to investigate the direct effects and subsequent consequences associated with the use of different transport protocols in a SIP context. Specifically, we seek to perform a comparative evaluation of UDP, TCP and SCTP based on a model simulating a scenario most likely to benefit from congestion(More)
Multisensory neurons integrate concordant visual-auditory cues in order to enhance the detection and reaction to such cross-modal events. As shown in studies of superior colliculus (SC) neurons, the magnitude of multisensory enhancement obeys a principle of inverse effectiveness: proportionately larger products are achieved when the effectiveness of the(More)
