extended abstract introduction the widespread and great inequalities in income generation, commonwealth, job opportunities and developmental facilities between urban and rural areas, have leaded the rural population towards the decline and in some instances the rural exodus. additionally, the rural poverty and deprivation has also caused major urban crisis, due to the vast rural migration and ...
In the current environment, the economic clusterization, which contributes to closer interrelations between the businesses operating within this system and promotes development of the involved regions, represents one of the key factors relating to competitive ability improvement of the active businesses. Identification and assessment of regional clusters is actually regarded as an insufficientl...
Analysis of the 16 polycyclic aromatic hydrocarbons (PAHs) of the US Environmental Protection Agency priority pollutant list was carried out in sediment samples of an industrial port in the southern Kaohsiung Harbor of Taiwan which is supposed to be extensively polluted by industrial wastewater discharges. The determination and quantification of PAHs in sediment samples were performed using gas...
The integrated development of Beijing-Tianjin-Hebei region has become one of the national economic development strategies in China. To understand this strategy, this paper studies the regional and industrial characteristics of the upcoming Beijing-Tianjin-Hebei (BTH) region, compares the BTH region with its existing counterparts in the Yangtze River Delta (YRD) region and the Pearl River Delta ...

In this paper, we explore the effect of oxygen supply on the conditions necessary to sustain a self-propagating front from a spherical source of heat embedded in a much larger volume of solid. The ignition characteristics for a spherical hot-spot are investigated, where the reaction is limited by oxygen, that is, reactant + oxygen → product. It is found that over a wide range of realistic oxyge...
We consider the base station placement problem for wireless sensor networks with successive interference cancellation (SIC) to improve throughput. We build a mathematical model for SIC. Although this model cannot be solved directly, it enables us to identify a necessary condition for SIC on distances from sensor nodes to the base station. Based on this relationship, we propose to divide the fea...
A complete dynamic wideband channel model for industrial wireless sensor network is presented. The model takes into account the noise, interferences, and heavy multipath propagation effects present in harsh industrial environments. A first-order two-state Markov process is adopted to describe the typical bursty nature of the impulsive noise usually present in industrial environments. The interf...
