Bus transportation performance must be able to demonstrate safety capabilities, one of which is the condition vehicle. Therefore, achieve bus vehicles' performance, research carried out determine causes accidents. This study aims accidents related vehicle conditions. Some variables that are observed include brake, wheel, equipment, stability, and worthiness. The data collection method used coll...

The indoor air quality in public transport systems is a major concern South Korea. Within this context, we investigated the effect of purification on intercity buses, one most popular options Air purifiers were custom designed and equipped with high-efficiency particulate (HEPA) filters to remove matter ultraviolet light-emitting diodes (UV-LEDs) airborne bacteria. To investigate effectiveness ...

Based on the boundary conditions obtained from actual measurements during infrastructure period of Jinghe Dongzhuang Power Station, a calculation model predicted bus bar hole environment was established, and full-scale numerical simulation performed based CFD to analyze effect air supply velocity changes temperature fields in working area. The ventilation is evaluated compared by calculating in...

The WDM-based multichannel dual bus networks (MCDBN) for high-speed LAN/MAN was proposed in the few years. When a station requests to connect to another, the transmitter of source station and the receiver of destination station must listen to a same channel (wavelength). The problem of using minimal wavelengths for a set of requests on MCDBN had been proved as NP-hard. Intuitively, the problem ...
