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...

The monitoring and warning of urban rail transit is the core of operation management, and the breadth and depth of the monitoring range directly affect the quality of urban rail transit operation. For the current domestic monitoring system, most of the critical equipments and technologies are introduced from abroad; it is diseconomy, and also causes hidden danger. Realizing the localization of ...

As peer-to-peer (P2P) applications (e.g. BitTorrent) impose high costs to Internet Service Providers (ISPs) due to the large volumes of interdomain traffic generated, extensive research work has been done concerning locality-awareness approaches. Although such approaches are based on properties of the physical network topology, they take very little consideration of the real business relationsh...

A station closure is an abnormal operational situation in which the entrances or exits of a rail transit station have to be closed for some time due to an unexpected incident. A novel approach is developed to estimate the impacts of the alternative station closure scenarios on both passenger behavioral choices at the individual level and passenger demand at the disaggregate level in a rail tran...

introduction: functional constipation is one of the most common gastrointestinal symptoms which could affect patients’ quality of life. the colonic transit time test could be used for determining functional constipation subtypes. the aim of our study was to determine the abnormalities of the subtypes of functional constipation using ctt. methods and materials: this cross-sectional study was per...

• Each table in the database has one column and stores the possible values for a ground fluent term. •Whenever there is complete knowledge about the term, the corresponding table has exactly one row. E.g., the ground fluent term door has only one possible value (Closed ) and so the table for door has exactly one row: Closed. •Whenever there is incomplete knowledge, the table has more than one r...

paper, we attempt to reconstruct the sitcalculus on a dense flow of time. The

Abstrac t This paper presents a procedure for wind speed measurement using ultrasonic transducers based on short-time Fourier transform (STFT). The measurement of wind speed was performed by estimating the ultrasonic transit-time (ToF). For this purpose the estimated ToF was used the technique of digital signal processing, based on the STFT. The ultrasonic signal detection was performed by sett...
