System-level buses consume much more power by orders of magnitude than on-chip buses. Existing bus encoding schemes are based on rail-to-rail CMOS bus drivers while recent high-performance devices include BiCMOS bus drivers to achieve transfer bandwidth required. BiCMOS drivers consume significant quiescent power as well as active power proportional to the bus frequency. This paper introduces a...

the aim of the study was to determine the prevalence of metabolic syndrome (mes) in professional bus drivers, and its association with overtime working hours among those drivers in urmia, iran. in this cross sectional study the studies population was 626 professional bus drivers, aged 20-69 yr. the mes (according to thenational cholesterol educationprogram adult treatment panel iii), waist circ...

In this paper, using longitudinal data on route level monthly average weekday ridership in the entire Chicago Transit Authority (CTA) bus system from January 2002 through December 2010, we evaluate the ridership effects of the CTA real-time bus information system. This bus information system is called CTA Bus Tracker and was incrementally implemented on different CTA bus routes from August 2006...

The air quality in air-conditioned mass transport buses may affect bus drivers' health. In-bus air quality improvement with the voluntary participation of bus drivers by opening the exhaust ventilation fans in the bus was implemented in the Seventh Bus Zone of Bangkok Mass Transit Authority. Four bus numbers, including bus numbers 16, 63, 67 and 166, were randomly selected to investigate microb...

BACKGROUND Our aim is to study the accuracy of emergency medicine (EM) physician-performed, bedside ultrasonography (BUS) in patients with clinical suspicion of scaphoid fracture and normal radiographs. METHODS From January to December 2011, an EM physician used BUS to prospectively evaluate patients presenting to the emergency department (ED) with clinical suspicion of scaphoid fracture and ...

Background Window opening during bus transportation is recommended as a tuberculosis prevention strategy.Yet, drivers are affected by lack knowledge and risk perception of passengers and assistants. Boosting knowledge of and notifying the high risk of tuberculosis transmission for every passenger could be too costly. However, strategies targeting bus drivers as key agents unlike targeting all p...

Bus systems in the United States are unattractive to many potential riders because of their lack of efficiency, especially with regard to travel time. One of the reasons services are not more efficient has to do with the spacing of bus stops. After using a nearest facility algorithm with an 800 m walking distance threshold to identify eligible bus stops in the current bus system in the city of ...

The network induced delay seriously effect the real-time and stability of CAN bus networked control systems. In this article, the structure of CAN bus NCS was analyzed, meanwhile studied the cause and integral part of delay. Then adopted TrueTime to build simulation model of CAN bus NCS. Discussed the effects of CAN bus network delay on performance of control system in three cases. Then drew a ...

Travel by bus with long hours will create discomfort feeling for bus passenger. Long hour travel will create physiological stress and psychological stress on bus passenger. It may due to vibration, noise, as well as seat comfort. Seat comfort is a subjective feeling of bus passenger. In this research, air cushion was used to replace the part of the seat foam. During the development of the integ...

This paper describes an efficient hardware implementation of a new technique for interfacing the data exchange between the microprocessor-based systems and the external devices. This technique, based on the use of software/hardware system and a reduced physical address, enlarges the interfacing capacity of the microprocessor-based systems, uses the Direct Memory Access (DMA) to increases the fr...
