Girish Varatkar Radu Marculescu Department of Electrical and Computer Engineering Carnegie Mellon University, Pittsburgh, PA 15213 USA Abstract The objectives of this paper are twofold: First, to introduce the self-similarity as a fundamental property exhibited by the bursty traffic between on-chip modules in typical MPEG-2 video applications. Indeed, statistical tests performed on relevant tra...

globally around 38 million people die each year as a result of non communicable diseases (ncds) in which 42% (~ 16 million) are premature deaths (below the age of 70). nine voluntary global targets were set by world health organization to control above mentioned premature deaths. iran added 4 more targets to it, including 20% reduction in the mortality rate due to road traffic injuries. the nee...

ATM networks are designed for the transmission of a wide variety of applications, each having different traffic characteristics. A Cellular Automaton (CA) can effectively generate random patterns which have good randomness characteristics. This paper makes the first step to use 1-D LHCA to generate random traffic distributions for ATM networks.

This paper discusses the concept of a structurally safe traffic system. The crucial question is how potential errors occurring in traffic can be reduced by revising the layout of the road environment. Two considerations play an important role: inherent safety and self-explaining properties. Inherent safety refers to the reduction of potentially dangerous encounters. Traffic systems having self-...

A rapid growth of the Internet and proliferation of new multimedia applications lead to demands of high speed and broadband network technologies. Routers are also necessary to follow up the growth of link bandwidths. From this reason, there have been many researches on high speed routers having switching capabilities. To have an expected effect, however, a control parameters set based on traffi...

A detailed traffic analysis of optical packet switch design is performed. Special consideration is given to the complexity of the optical buffering and the overall switch block structure is considered in general. Wavelength converters are shown to improve the traffic performance of the switch blocks for both random and bursty traffic. Furthermore, the traffic performance of switch blocks with a...

We consider a queue fed by Gaussian traffic and give conditions on the input process under which the path space large deviations of the queue are governed by the rate function of the fractional Brownian motion. As an example we consider input traffic that is composed of of independent streams, each of which is a fractional Brownian motion, having different Hurst indices.

This study examined the associations between perceived neighborhood and home environmental factors and excessive television (TV) viewing time among Taiwanese older adults. The sample data was collected by administering computer-assisted telephone interviewers to 980 Taiwanese older adults (aged ≥ 65 years) living in two regions. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculat...

In this article, a new technique for grooming low-speed traffic demands into high-speed optical routes is proposed. This enhancement allows a transparent WavelengthRouting Switch (WRS) to aggregate traffic en route over existing optical routes without incurring expensive Optical-ElectricalOptical (OEO) conversions. This implies that: a) an optical route may be considered as having more than one...

The railway system is vulnerable to disruptions that require careful management of available infrastructure capacity in order to keep operations feasible and attractive for passengers and for the environment. Dispatchers manage traffic with a limited view on the network impact of their actions. Effective large scale dispatching solutions are required to better forecast the delay propagation in ...
