The mobility of modern metropolises strongly relies on urban rail transit (URT) systems, and such a heavy dependence causes that even minor service interruptions would make the URT systems unsustainable. This study aims at optimally dispatching the ground feeder-bus to coordinate with the urban rails' operation for eliminating the effect of unexpected service interruptions in URT corridors. A f...

The Bus Rapid Transit (BRT) station is the interface between passengers and services. The station is crucial to line operation as it is typically the only location where buses can pass each other. Congestion may occur here when buses maneuvering into and out of the platform lane interfere with bus flow, or when a queue of buses forms upstream of the platform lane blocking the passing lane. Furt...

Urban mobility involves many interacting components: buses, cars, commuters, pedestrians, trains etc., making it a very complex system to study. Even bus responsible for delivering commuters from their origins destinations in loop service already exhibits complicated dynamics. Here, we investigate the dynamics of simplified version such consisting two buses serving three stops. Specifically, co...

background: educational centers have higher standards for controlling noise pollution as it has been shown that noise pollution is a major cause of discomfort for teachers and students. noise pollution reduces concentration, interferes in the conversation, and leads to dropouts and lower grades especially in mathematics. the present study aimed to evaluate noise pollution in the schools of birj...

In this paper we present a comprehensive mathematical analysis of the energy dissipated in deep sub-micron (DSM) buses. The estimation is based on an elaborate bus model that includes all the distributed and lumped parasitic elements that appear as technology scales. The energy drawn from the power supply during the transition of the bus is evaluated in a compact closed form. The notion of acti...

Multi-Chip Module design is an increasingly common design style for integrated circuits. The area taken up by buses in a multi-chip module design has a signiicant eeect on the size of the circuit. This paper considers several diierent methods that reduce the required number of buses. Two models of interchip communication are studied. The rst, called immediate transfer, requires that all values ...

In this paper we consider the use of optical slab waveguides as buses in a parallel computing environment. We show that slab buses can connect to many more elements than conventional electrical or ber optic buses. We also introduce a novel multiplexing scheme called mode division multiplexing that vastly increases the number of independent channels that a single slab can support. We show that o...
