Automatic Generation Control (AGC) and Automatic Voltage Control (AVC) are key approaches to frequency and voltage regulation in power systems. However, based on the assumption of decoupling of active and reactive power control, the existing AGC and AVC systems work independently without any...

China's CO2 emission has attracted world's attention in the last few years for its rapid increase. It is necessary to analyze the current situation of China's carbon emission for its CO2 reduction. Carbon flow chart is an intuitive and quantitative tool for showing a whole picture of CO2 flows...

This paper analyzes the effect of applying a combined cooling, heating and power (CCHP) system in two types of buildings: residential and office buildings in Dalian, China. The CCHP system configuration was optimized by adding an air-conditioning system (AC) and a heat storage tank (HST) in each...

Combined Cooling, Heating and Power (CCHP) systems have been widely used in different kinds of buildings to make better use of fuels because of their high overall efficiency. This paper presents a mathematical analysis of a CCHP system in comparison to a Heating, Ventilation and Air Conditioning...

This paper investigates how the introduction of heterogeneous relationships and the subsequent investment preference influences the evolution of cooperation in prisoner’s dilemma games. We consider random tie strength values drawn from distributions with different heterogeneity. We show that...

This paper compares the competitive advantages of high technology products export from BRIC countries to the United States using quantitative (ESI and RCA index) and qualitative analyzingof export value and distribution performance. We estimate a Varying Coefficient Model on panel data for BRIC...

Consumer services such as airlines and hotels include a proliferation of bookings through Internet-proprietary and Internet-third party sites. The other dominant channel for making airline and hotel purchases is via telephone. This research investigates differences in how buyers utilize the...
