This paper proposes split shared-bus architecture to reduce the energy dissipation for global data exchange among a set of interconnected modules. The bus splitting problem for minimum energy is formulated as a Minimum-Exchange Bus Split problem, which is shown to be NP-complete. The problem is solved heuristically by using a max-weight matching algorithm and combinatorial search. Experimental ...

This study presents the conceptual design of an intersection bus-pedestrian collision warning system for bus drivers approaching an intersection. The basic parameters of the proposed design concept include the bus drivers’ perception-reaction time, the emergency deceleration rate of the bus, and pedestrian walking speed. A bus driving simulation was designed and conducted to analyze bus drivers...

Bus: A bus is a shared interconnect used for connecting multiple components of a computer on a single chip or across multiple chips. Connected entities either place signals on the bus or listen to signals being transmitted on the bus, but signals from only one entity at a time can be transported by the bus at any given time. Buses are popular communication media for broadcasts in computer systems.

This paper describes the design of the Bus Timetabling System (BTS) we have developed for one of the largest privately held bus companies in the world. This Bus Company operates close to 3,500 buses and employs over 7,500 bus drivers. The BTS generates a timetable for each bus route using “distributed constraint-based search” (DCBS). The DCBS algorithm combines techniques of constraint programm...

The bus-invert method, proposed by M. R. Stan and W. P. Burleson [l], is a simple and yet effective method to reduce data-bus switching activity if the switching of data lines is spatially and temporally independent and uniformly distributed. Suppose the bus is n-bit wide. The bus-invert method can reduce not only the average switching activity of the I/O bus, but also the peak switching activi...

The performance of a system, especially a multiprocessor system, heavily depends upon the efficiency of its bus architecture. This paper presents a methodology to generate a custom bus system for a multiprocessor System-on-a-Chip (SoC). Our bus synthesis tool (BusSyn) uses this methodology to generate five different bus systems as evaluate the performance of each bus system in the context of tw...

The objective of optimal feeder reconfiguration of radial distribution system problem is to obtain the best set of branches to be opened, one each from each loop, such that the resulting radial distribution system has the desired performance. This paper presents a feeder reconfiguration problem in the presence of distributed generators to minimize the system power loss while satisfying operatin...

in this paper, a novel multi-objective bus stop location model is proposed, which considers not only the coverage of demand and minimization of access time but also the necessities of suitable stops for transit network design phase. three objective functions are considered including minimizing (i) sum of the total access distance (time), (ii) the weighted combination of stops, and (iii) the num...
