Traditional Savonius wind turbine has advantages such as simple structure, fast start-up, etc., however, it also has significant disadvantages of low wind energy utilization efficiency. A novel wind turbine is proposed by improving structure of Savonius wind turbine in order to increase the low wind energy utilization efficiency. To compare performance of the novel wind turbine and the Savonius wind...
This paper investigates a kind of computer algorithm for analyzing the stability and stabilization of nonlinear continuous-time singular dynamic Leontief input-output model. A new mathematic method is applied to directly study the singular dynamic input-output systems instead of transforming the singular systems into general systems. With the computer analysis algorithm derived from this paper, the...
Using an aggregate production model where capital, labor and energy are treated as separate inputs, this paper tests for the existence and direction of causality between output growth and oil consumption in China. Using the Johansen cointegration technique, the empirical findings indicate that there exists long-run cointegration among output, labor, capital and oil consumption in China. Then using...
