With the wide adoption of alternate wetting and drying (AWD) irrigation for rice production, the water and nitrogen (N) fate in lowland paddy fields under AWD irrigation was needed to be investigated for assessing the water saving and environmental effects of AWD, compared to traditional...

The widely adopted alternate wetting and drying (AWD) irrigation for rice production in lowland paddy fields with shallow groundwater table is increasingly needed to quantify the soil water regime for irrigation schedule design. Field experiments were conducted to compare the soil water flow...

Scientifically forecasting gross domestic expenditure devoted to research and development (GERD) and the ratio of GERD to GDP in the future is an important task in formulating long-term S&T development policies in China. For quite a long time, China mainly adopted expert opinion based on...

In this paper, the energy efficiency of airlines has been studied with number of employees, capital stock and tons of aviation kerosene as the inputs and Revenue Ton Kilometers, Revenue Passenger Kilometers, total business income and CO2 emissions decrease index as the outputs. A new model,...

In this paper, transportation carbon efficiency is redefined, and its inputs and outputs are obtained from a literature review. Carbon, capital and labor are selected as the inputs, and passenger turnover volume and freight turnover volume are defined as the outputs. A new model, a virtual...

In many remote areas, expensive fossil fuels such as diesel are used to meet local electricity demand. However, their environmental impact is significant. Consequently, some of these areas have started to use hybrid systems that combine renewable energy sources and fossil fuel generation, such...

During the last decade, the development of tidal current industries has experienced a rapid growth. Many devices are being prototyped. For various purposes, investors, industries, government and academics are looking to identify the best device in terms of of cost of energy and performance....

Three-dimensional effects in studying a vertical axis tidal current turbine are modeled using a newly developed vortex method. The effects on predicting power output and wake trajectory are analyzed in particular. The numerical results suggest that three-dimensional effects are not significant...

Energy shortage is exacerbated by energy wastage and low efficiency, so energy efficiency has become a popular research topic. However, in most studies, the inputs and outputs of energy efficiency are selected through qualitative analysis and literature review, the rationality is not convincing....

We model banks’ liquidity holding decision as a simultaneous game on an interbank borrowing network. We show that at the Nash equilibrium, the contributions of each bank to the network liquidity level and liquidity risk are distinct functions of its indegree and outdegree Katz-Bonacich...
