Sustainable Development Model of Production Increase with Energy Conservation in Wuhan Iron and Steel

Dai Lin,Zhou Huoqing,Tian Zhiyu

Strategic Study of CAE 2006, Volume 8, Issue 12,   Pages 31-38

Abstract:

In March 2006，《The Outline of the 11th Five-Year Plan for National Economic and social Development (Profile)》stated that energy consumption per unit of GDP will be reduced by about 20% in “The 11th Five-year Plan ” period，which indicates the economic growth is transferring from conventional industrialization to new pattern. Due to the economic structure emerging with high energy intensity in “The 10th Five-year Plan”period, the proportion of energy consumption of industrial sector had gradually increased from 68.63% to about 71% of the national energy consumption. Apparently, iron and steel industry had experienced its rapid growth with the steel output increasing from 128.5 million tons to 352.39 million tons and the annual growth rate of 22.36% . Its energy consumption accounted for 21 % of the whole industrial energy consumption. Therefore, how to realize the sustainable development of increasing the output while reducing the energy consumption in those high-energy intensity enterprises would provide the good reference to the industrial sector, even to the whole country. Based on the investigation and analysis on WISCO, some important inspiration and experiences were summarized.

Keywords： Wuhan Iron and steel Corporation     energy consumption per unit of GDP     energy conservation     sustainable development

A comprehensive error calibration method based on dual uniform circular array Research Article

Jia-jia Zhang, Hui Chen, Song Xiao, Meng-yu Ni,zjj2015wuhan@163.com

Frontiers of Information Technology & Electronic Engineering 2019, Volume 20, Issue 10,   Pages 1415-1428 doi: 10.1631/FITEE.1800240

Abstract: Based on the , a novel method is proposed to estimate the direction-of-arrival (DOA) and jointly calibrate , , and . In this paper, only one auxiliary source is required to generate three time-disjoint sources with the help of the rotation platform. Subsequently, according to the principle that the signal subspace is orthogonal to the noise subspace, the cost function is constructed. The alternating iteration method is used to estimate the coefficients of the three kinds of errors. During the process, the proposed algorithm makes full use of the structural characteristics of the array when estimating , while the signal phase matrix is used to eliminate the phase influence caused by the delay in signal arrival at the antenna array when estimating and . Compared with the algorithm using multidimensional nonlinear search, the proposed algorithm has lower computational complexity. Moreover, our algorithm does not require additional auxiliary sensors. Simulation results demonstrate that the proposed algorithm is effective and can precisely and comprehensively calibrate the errors in a .
