Published: July 2019

Abstract
The China Optimized Development Area was officially released in the National Main Functional Area Plan in 2011. It is an important population and economically intensive area of China and has a huge impact on China’s future development. Under the background of international commitment and national planning to reduce carbon emission intensity, China’s optimized development area should play a leading role. Based on the location quotient analysis method, this paper analyzes the basis and prospects of optimizing the development area to take the lead from the industrial structure level, and draws the following conclusions. From the perspective of a single city, it compares with the overall industrial structure of the country and obtains optimization. Compared with the whole country, the development zone has a better industrial structure as the basis for carbon emission peaks. The optimized development zone should continue to carry forward its advantages in industrial structure and play a leading role in China’s 2030 carbon emission peak.
Time Series Generation and Complex Correlation Assessment for Multiple Wind Farms
Authors: Xu Shenzhi , Xu Bo 
Published: July 2019

Abstract
Analysis and calculation of power system often requires a large number of medium and long-term wind power output series as data foundation. However, for most wind farms that have not been built or put into operation for a long time, the current output data is limited and it is difficult to support related research. It is necessary to use a limited amount of measured data to generate lots of wind power output time series that are similar to the actual data. Considering the concentrated development mode of wind power, this paper proposes a time series generation method for multiple wind farms based on the Markov Chain and Monte Carlo (MCMC) method and combined with high-dimensianal Markov process. The mixed Copula function fitting model is used to describe the spatial correlation of wind farms accurately. The measured wind power ouput is used to verify the results. It shows that the proposed method can simulate the output characteristics of single wind farm while maintaining the spatial correlation among different wind farms with geographical proximity

Abstract
With the rapid development of the modern economy, the importance of improving energy efficiency and reducing environmental pollution is increasing. Developing an ecological economy is an inevitable course to achieve sustained economic growth. In order to ensure the smooth development of the green economy, the government has introduced a series of environmental protection policies. Meanwhile, a large number of environmental protection and green industries have emerged. However, the economic impact of environmental policies on environmental protection and green industries is difficult to predict. Environmental policy in national level promulgated more frequently, but these policies specifically for environmental protection industry green industry and environmental policy is not much. So the analysis of the process focused on Water Pollution Control Action Plan and public service in-depth promotion of government and social capital cooperation work notice. Results show that the Water Pollution Control Action Plan has a binding effect on the yield of green industries and public service in-depth promotion of government. In contrast, public service in-depth promotion of government and social capital cooperation work notice increases the income of the environmental protection industry, and it has a negative constraint on the green industry.

Authors: Junwen Chen , Gang Zhao , Hua Zhang 
Published: July 2019

Abstract
An energy consumption prediction method based on process parameters and neural network was proposed to study the inherent energy consumption characteristics of open source melt deposition 3D printer and improve energy efficiency. An improved regularized network is used for optimization to avoid over-fitting and under-fitting problems. The orthogonal test sample data were trained in MATLAB environment, and the predictive model between process parameters and energy consumption of open source melt deposition 3D printing was established. The energy consumption prediction results of BP networks and regularized networks are compared by analyzing convergence curves and network training charts. The results show that the BP network training has experienced over-fitting, resulting in a prediction energy consumption error of about 10%. The improved regularization method effectively avoids the over-fitting phenomenon and the error of energy consumption prediction is about 1%. It can effectively improve the calculation efficiency of energy consumption prediction, which shows the accuracy of this method in energy consumption prediction.

Abstract
ACARS is a digital data link system that transmits short messages by radio or satellite between aircraft and ground stations. ACARS control centre is connected with each ACARS ground station and each airline information centre through the ground communication network. Exchange data and information with airlines in both directions through code addressing. However, because ACARS messages use plaintext transmission, anyone can monitor and decode ACARS messages with a low-cost receiver and obtain details such as aircraft type, location, planned route, passenger status and aircraft operation state, etc., thus posing a major threat to flight safety. The following security problems exist in the current ACARS system.

Authors: Xiao Li-guang , Liu Xi-xu 
Published: July 2019

Abstract
This paper mainly studies the effect of Diatomite Content on the thermal insulation performance of straw fiber cement-based composites. The test shows that 30% sulphoaluminate cement is replaced by ordinary Portland cement. XRD test showed that the diffraction peaks of Ca (OH)2 and Ettringite were stronger than those of ordinary Portland cement, and the crystallization effect was better. The compressive strength and flexural strength increased by 7.6% and 20% respectively. With the increase of diatomite content, the dry density and thermal conductivity of the composite decreased. When diatomite content was 25% of the total cementitious material, the dry density of the composite was 1068.37 kg/m3, and the thermal conductivity could reach 0.1163 W/(m.K). The thermal insulation performance of the composite could be significantly improved by adding diatomite.

Published: July 2019

Abstract
A granulated biosorbent-Ni-SC (Ni2+ ions imprinted seaweed-chitosan) was made by seaweed powder encapsulated with cross-linked chitosan and ion-imprint technology in this study. Ni-SC and granulated SC biosorbent (without ion-imprint technology) were investigated for nickel ions removal. The maximum nickel adsorption capacity of Ni-SC and SC were both achieved at pH 7.0 and the capacity of Ni-SC was higher than that of SC. The diffusion-controlled model and pseudo-second-order model were used to fit the adsorption kinetics data. The adsorption capacity of Ni-SC was higher than that of SC during the whole kinetics process. Also the adsorption isotherm study showed that the maximum adsorption capacity of Ni-SC (0.99 mmol·g−1) was higher than that of SC (0.41 mmol·g−1). The Thomas model can well describe the dynamic adsorption observations and the maximum column adsorption capacity qmax was 0.24 mmol·g−1.

Authors: Liu Yuan 
Published: July 2019

Abstract
Activated carbon and quicklime were used to prepare complex calcium based adsorbent for flue gas desulphurization. The desulfurization properties of adsorbent were analyzed on fixed bed. The results showed that the desulfurization effect of the composite adsorbent was best when the ratio of activated carbon to calcium was 1:2, the water heating time was 24 hours and heating temperature was 90 °C. At the same time, low temperature plasma technology is used to ionize the composite adsorbent, increase the number of surface chemical functional groups of the adsorbent, and then improve its desulfurization efficiency. The effect of modification time and power on desulfurization efficiency was studied. The results show that low temperature plasma ionization modification can obviously improve the desulfurization performance of composite adsorbent.
