Given the security problems of the urban rail transportation, this paper proposes a methodology for congestion risk evaluation and precaution in order to guarantee the safety of passengers and improve the operation efficiency in metro stations. To begin with, we selected the retention rate of the platform, the waiting rate of the ticket gate and the transfer efficiency as the indexes for the st...

Wireless sensor networks(WSN) are an exiting emerging technology that scientists believe to become a part of every day life in the next few years. However, at this time many issues in wireless sensor networks remain unresolved. This paper studies the architecture of a neural wireless sensor network designed to identify technical condition of the base station of wireless sensor networks ,and thi...

This position paper presents the preliminary design insights for ParkPal — an interactive system for supporting social running route planning in a city park. Based on our previous research efforts in augmenting the experiences of runners and ad-hoc multi-device interactive spaces, we propose a system composed of multiple station deployed in a city park. The stations contain tablet computers tha...

The waste intermodal station of Clyde, in the city of Sydney, Australia, is in the heart of a complex network of terminals connected by road and rail to transport urban waste from its first collection to its final disposal. The amount of waste the network is projected to handle in 2015 will increase from about 340,000 tonnes/year in 2006 up to about 1.5 million tonnes/year, following population...

New and forthcoming Earth Observation satellite missions include in their payloads remote sensing instruments of very low spatial resolution. Data and product validation from these sensors introduces a set of specific scientific issues that make it necessary to carry out specific measurements over large extended areas. The main objective of the VALENCIA Anchor Station is to define a reference a...

Abstract City Gate Stations (CGS) are critical elements of Natural Gas (NG) distribution systems, as they connect national high-pressure transmission networks with local low-pressure networks. One their main tasks is to pre-heat the gas avoid dangerous sub-cooling due Joule-Thompson effect after pressure reduction stage. For this process, significant amounts thermal energy required, usually obt...

This document reports on a carefully designed set of fixed and mobile reception tests in Mexico City on the DRM (Digital Radio Mondiale) system at a frequency in the uppermost shortwave broadcasting band – around 26 MHz – for local broadcasting. The testing was done during July 2005. These were not operational tests; that is, neither the transmitter antenna, nor antenna location, nor transmitte...

Niigata City can be easily accessed from Tokyo by the JR Joetsu Shinkansen (100 min.), which arrives approximately every 30 min. Niigata Airport has direct flights from Nagoya Chubu Centrair, and Osaka International Airport, and is also an international gateway with regular flights from Harbin, Incheon, Shanghai, Taipei and other international cities. It takes 25 min. by bus from Niigata Airpor...

We present a simulation methodology for generating the locations of stations in Bicycle-Sharing Systems. We present several methods that are inspired by the literature on spatial point processes. We evaluate how the artificially generated systems compare to existing systems through a case study involving 11 cities worldwide. The method that is found to perform best is a data-driven approach in ...

Aims: To compare the vitamin D status of 34 children, 9–24 months old, living in an area of Delhi renowned for high levels of atmospheric pollution (Mori Gate), with a comparable age matched group of children from a less polluted (Gurgaon) area of the city. Methods: Serum concentrations of calcium, alkaline phosphatase (ALP), parathyroid hormone (PTH), 25-hydroxyvitamin D (25(OH)D), and 1,25-di...
