Traffic modeling is an important tool for performance evaluation of networks. Simple models like Poisson process have been discredited in modeling Internet traffic. At the same time, characterization studies of Internet traffic revealed the presence of different types of correlations in Internet traffic. In this paper, we explore the use of M|G|infin process in capturing traffic correlations. We use...
Session initiation protocol (SIP) is a session signaling protocol designed to establish multimedia sessions (voice, video and data). Meanwhile multimedia applications are sensitive to the quality of service (QoS) provided by the underlying network. Therefore SIP could manage QoS for multimedia sessions by interacting with QoS mechanisms deployed in IP networks, and especially in DiffServ domain. In...
The present study addresses the question whether metabolic dopamine can be immunocytochemically detected within non-dopaminergic catecholaminergic axonal fibers. For this purpose, confocal microscopy was used to analyze sections treated for the double fluorescence immunostaining of dopamine and either noradrenaline or phenylethanolamine-N- methyltransferase (the enzyme in adrenergic neurons that...
