This study aims to investigate the spatial variation in the characteristics of water quality monitoring sites, identify the most significant parameters and the major possible sources of pollution, and apportion the source category in the Kinta River. 31 parameters collected from eight monitoring sites for eight years (2006-2013) were employed. The eight monitoring stations were spatially groupe...

Rail transit is developing rapidly in major cities of China and has become a key component of urban transport. Nevertheless, the security and reliability in operation are significant issues that cannot be neglected. In this paper, the network and station vulnerabilities of the urban rail transit system were analyzed based on complex network and graph theories. A vulnerability evaluation model w...

The long-term changes in the main tidal constituents (O1, K1, M2, N2, and S2) along the coasts of China and in adjacent seas are investigated based on 17 tide-gauge records covering the period 1954– 2012. The observed 18.61 year nodal modulations of the diurnal constituents O1 and K1 are in agreement with the equilibrium tidal theory, except in the South China Sea. The observed modulations of t...

The improvement of the exploitation of energy resources in power stations is a topic of growing interest. However, experimentation costs in order to increase productivity are very high, either because the possible equipment to change would be very expensive, or simply, because the plant would have to stop. In such cases, the simulation is a fast and cheap way to analyze the power plant behavior...

In recent decades, a decrease in snowfall attributed to the effects of global warming (among other causes) has become evident. However, it is reasonable to investigate meteorological causes for such decrease, by analyzing changes in synoptic scale patterns. On the Iberian Peninsula, the Castilla y León region in the northwest consists of a central plateau surrounded by mountain ranges. This cre...

Suspended solids or sediments can be pollutants in rivers, but they are also an important component of lotic food webs. Suspended sediment data for rivers were obtained from a United States-wide water quality database for 622 stations. Data for particulate nitrogen, suspended carbon, discharge, watershed area, land use, and population were also used. Stations were classified by United States En...

Intelligent networks are becoming more enveloping and dwelling a new generation of applications are deployed over the peer-to-peer networks. Intelligent networks are very attractive because of their role in improving the scalability and enhancing performance by enabling direct and real-time communication among the participating network stations. A suitable solution for resource management in di...

IceTop, the surface component of the IceCube neutrino telescope at the South Pole, is an air-shower array which will finally consist of 160 ice Cherenkov tanks at 80 stations spread over an area of 1 km. Currently 40 stations are deployed and taking data. The detector is designed to cover the energy range above the knee up to about 10 eV and study the mass composition of primary cosmic rays. In...

The traditional urban public transport system generally cannot provide an effective access service for people with disabilities, especially for disabled, wheelchair and blind (DWB) passengers. In this paper, based on advanced information & communication technologies (ICT) and green technologies (GT) concepts, a dedicated public urban transportation service access system named Mobi+ has been int...
