This paper presents the application of a modified fuzzy reasoning spiking neural P systems (MFRSN P system, for short) to fault diagnosis of metro traction power supply systems. In MFRSN P systems, three types of neurons are used to represent operation information of protection devices including protective relays and circuit breakers; a reasoning algorithm associated with MFRSN P systems is int...

En Chile, durante el ‘estallido social’ de octubre 2019, hubo estaciones la red metro Santiago que fueron foco constante violencia y destrucción, muchas ellas resultaron parcial o completamente siniestradas. Este evento histórico —entre otras cosas— dio paso al inicio del proceso constituyente, cual se votó en plebiscito entrada año 2020 tuvo las opciones Apruebo Rechazo a redacción una nueva c...

Population density varies widely among U.S. metro areas. A simple, static general equilibrium model demonstrates that moderate differences in metro areas’ consumption amenities can cause extremely large differences in their population density. Such amenities are more strongly capitalized into housing prices than into wages. Empirical results suggest that amenities do indeed help to support high...

This paper analyzes the impact of metro station proximity on property value from both theoretical and empirical perspectives. Data on second-hand apartments within six kilometers of metro line 1 and 2 stations in Nanjing are used. Our empirical results show that metro station proximity has a positive partial effect on property value. The degree of impact diminishes with the increase of the dist...

Metro systems are one of the most important transportation systems in people’s lives. Due to the huge amount of energy it consumes every day, highly-efficient operation of a metro system will lead to significant energy savings. In this paper, a new integrated Energy-efficient Operation Methodology (EOM) for metro systems is proposed and validated. Compared with other energy saving methods, EOM ...

When providing travel guides for a specific route in a metro network, we often place the route around the center of the map and annotate stations on the route with thumbnail photographs. Nonetheless, existing methods do not offer an effective means of customizing the network layout in order to accommodate such large annotation labels while preserving its planar embedding. This paper presents a ...

In this paper we investigate the effect of the Delhi Metro, an intra-city mass rail transit system, on air pollution within Delhi. To identify effects on pollution, we exploit the discontinuous jumps in metro ridership, each time the network is extended. Our identifying assumption is that in the absence of the extension there would be a smooth transition in pollution levels. We find strong evid...

In this paper, we explore whether the geography of bank services has been converging toward the market since banking geographic deregulation. We use Illinois as a study area and examine changes in various market segments such as metro and non-metro markets, and regional markets. We adopt the Spatial Concentration Index (SCI) and the related supply and demand SCI deviations to measure changing s...
