In the 21st century, electricity supply will face more and more challenges, trends of lowcarboneconomy and energy conservation work requirements for safe and reliable operationof power systems and green economic development put forward new and higherrequirements. With the increasing complexity of the power system and power systemoperating environment continues to advance, the traditional power network...
In this paper, based on the reality that holiday load is in a “trough” segment relative to the annual load curve, we intend to set up a preferential price during the holidays, through economic levers to encourage some industrial enterprises to go into operation in order to achieve the effect of valley filling. We can calculate the preferential price when achieving the target the electricity enterprises...
According to the National Standard of the People's Republic of China <Agricultural Safety and Quality of Agricultural Products — Pollution-free Vegetable Production Environment Requirements> (GB/T18407.1-2001), environmental quality assessment of heavy metal in soil of pollution-free vegetable produced in Hebei Plain Area was carried out. The results by the single-index model indicated that...
The characteristics of spatio-temporal distribution of tropospheric NO2 vertical column density (VCD) over Yangtze Delta(YD) are presented, on the basis of measurements from the satellite instruments Ozone Monitoring Instrument(OMI). From these observations, monthly and yearly averaged tropospheric NO2 variations are determined for the period of 2005-2009. A linear regressed model is used to fit the...
The tight coupling between the data and the layout of the spreadsheets is one of the important problems in spreadsheet systems. The existing solutions are lack of flexibility and inefficiency in data retrieval. To improve the performance, a concept of data semantic object is introduced which encapsulate the data and its semantic in an object. The objective is to decouple the data and structure in...
Water and chloroform extracts of various Chinese medicinal insects were added into the medium of Ganodermasinense to investigate the effects of the extracts on production of biomass, intracellular polysaccharides (IPS), and extracellular polysaccharides (EPS). The results showed that chloroform extract of E. sinensis (CES) at 55 mg/L lead to significant increase in both biomass and IPS concentration...
To screen stimulators for mycelial growth and polysaccharides production of Ganodermalucidum, the fungus was inoculated into the media with and without supplementation of several fatty acids and ether extracts of Chinese medicinal insects. Palmitic acid at 1.0 g/L lead to significant increase in both biomass and extracellular polysaccharides (EPS) concentration from 7.73 plusmn 0.41 to 10.21 plusmn...
Alliances bring firms some advantages. A good and stable buyer-supplier relationship is crucial in a firm alliance. In this study, we develop an agent-based model to study how the myopic behavior of retailer in a distributed supply chain affects the whole supply chain alliance. We investigate the effect of firm's myopic behavior both in stable and dynamic environment including competition for price...
