Fossil resources, i.e. concentrated carbon from biomass, have been irrecoverably exhausted through modern industrial civilization in the last two hundred years. Serious consequences including crises in resources, environment and energy, as well as the pressing need for direct and indirect exploitation of solar energy, pose challenges to the science and technology community of today. Bioenergy, bulk...
Traffic prediction is of significant importance for telecommunication network planning and network optimization. In this paper, the traffic series from a certain mobile network in Heilongjiang province in China is studied. The characteristics in respect of both trend and periodicity are explored with autocorrelation function. Based on the characteristics exhibited in the traffic series, multiplicative...
China's coastal region is physically and socio-economically vulnerable to accelerated sea-level rise and associated coastal flooding because of its low topography, highly developed economy and highly-dense population. In this study, we present a scenario of sea level rise and storm surge flooding along the China's coastal region over the next century and apply them to a digital elevation model (DEM)...
Based on the data of high-tech industry in China during 1998-2007, the paper calculates the level of specialization, diversity and competition of high-tech industry. From the perspective of industrial added value and patents, the paper establishes the panel data model to analyze the impact of growth and innovation of high-tech industry from its agglomeration effect. The result shows that strong positive...
Based on the overview of the theory and measurement methods of specialization and diversification, this paper calculate the specialization and diversification level of equipment manufacturing industry from the perspective of sector and regional separately in China during 1993~2007. Then the paper establish panel data model to analysis the spillover effects of specialization and diversification. The...
The fundamental of neural network and its application are introduced firstly. Then the main factors which affect the runoff and the sediment transport volume in the problems of the water and sediment fluxes in the Yellow River Mouth during the flood and non-flood period are analyzed. Furthermore, the BP model is set up by using the program in the toolbox of the neural network under the environment...
This paper addresses energy measurement audit in coal-fired power plant. Energy audit, as an effective energy-saving and emission-reducing measure, was launched in thousands of high energy-consuming enterprises in China in 2006. The big part of energy audit is energy measurement audit. In this paper, the work center of energy measurement is obtained by analyzing the contents and characteristics of...
The European Union Allowance (EUA) futures traded on European Climate Exchange (ECX) is selected to represent the Greenhouse Gas Emission Permits (carbon assets) in this paper. The Copula function is applied to get the joint distribution function of the return rates of EUA futures and a Qualified Domestic Institutional Investor (QDII) fund in China. Based on the joint distribution function of the...
The waterlogging is one of the most serious hazards in Shanghai. The method of scenario simulation was applied to assess the waterlogging hazard on roads in the central urban districts of Shanghai. Two scenarios were simulated by the rainstorm simulation model in Shanghai Flood Risk Information Center and a hazard assessment model was built to compare the disaster situation among different regions...
Injecting drug use(IDU) has been the dominant route for HIV infection in China, especially in Yunnan province and the HIV epidemic is a complex phenomenon in the world today. The most profound factor in the proliferation of this disease is the aggregate effects of individual behavior and perception of risk. Agent-based modeling (ABM) is the dominant paradigm in social complex network simulation which...
Remote sensing technique has advantages in exploring the spatiotemporal trends of urbanization compared with traditional socioeconomic indicators (e.g. population growth, employment shifts, etc.). Details in urban change and growth can be effectively identified using multi-temporal images of remote sensing by multi-scales analysis approaches at the metropolitan, city or district level. In this study,...
Communication is important for successful services, and media selection is the key for communication. However nearly all previous research focused on qualified researches. In this research, quantified analyses on media selection in IT and consulting companies are made using media fitness framework (MFF). Moreover, selections from China and Japan were compared. FTF and email are found to be two of...
