Authors: Chen Changkun , Cao Sai , Xu Tong 
Published: August 2019

Abstract
It is particularly necessary to prevent the occurrence of wildfires, which caused a series of economic losses and ecological disasters. In this paper, an evaluation model is established by the combination of Triangular Fuzzy Theory and FTA (F-FTA). Considering the human and environmental errors in the wildfire fault, the triangular fuzzy probability, error limits and importance degree of the events are adopted, and the causes of probability fluctuation and proper measures are raised. In addition, this model is applied in Zhaotong, Yunnan to analysis the potential risk of wildfires. The result shows that the triangular fuzzy probability of local wildfire fault is (0.0024, 0.021, 0.071), and the probability of wildfire occurrence fluctuates greatly. Especially, Sacrificial fire (X18
), Burning Charcoal (X8
), Burning woodland (X9
), Smoking in the wild (X16
), Burning pasture (X10
), Children playing with fire (X20
) exist highly risk. Therefore, fire-fighting equipment should be arranged flexibly, and individualized measures should be formulated in response to the accidental occurrence of wildfires to provide guidance for the prevention and control of wildfires faults.

Published: August 2019

Abstract
CO2 mineral sequestration has significant advantages such as safety and permanence, but its industrial application is limited by high costs. Combining CO2 mineral sequestration with existing industrial processes can make it economically viable by integrating ore extraction, crushing and grinding, and avoiding the construction of new carbonation plant. In this paper, CO2 mineral sequestration was combined with the leaching of sodium sulfate from glauberite. The dissolution behavior and carbonation process of glauberite ore were studied in detail. The influences of key parameters such as ammonia dosage, CO2 pressure and temperature were also investigated. The results showed that under the optimal conditions (ammonia dosage 110%, CO2 pressure 5 bar, temperature 100°C), the carbonation rate of glauberite can reach 93.4%, while the concentrations of sodium ion and sulfate ion were 25.8g/L and 53.8g/L, respectively. The increase of ammonia dosage and CO2 pressure contributed to the dissolution and carbonation of glauberite. Temperature, however, affected them in two very different ways.

Authors: Li Shunyou , Zhou Dandan , Jin Xiuqi , Liu Yang 
Published: August 2019

Abstract
The spatial interpolation method is of great sign ificance for the spatial distribution of heavy metals in soil and the prevention and control of pollution. However, different interpolation methods are applied to predict the accuracy of different heavy metal pollution distributions in small-scale areas with a single farmland. There is no relevant argument. Taking a farmland (96000m2) in Lanping County, Yunnan Province, Yunnan Province as the research object, 144 surface soil samples were collected and the contents of Pb and Cd in soil were determined by ICP-MS. The deterministic spatial interpolation method and geostatistical Kriskin interpolation method were used to investigate the accuracy of different interpolation methods and the distribution characteristics of Pb and Cd in soil. The results show that the optimal interpolation methods for heavy metals Pb and Cd in polluted farmland are 0-order ordinary Kristen interpolation method, and the content of Pb and Cd in the soil is relatively accurate. This study will provide important basic information for the identification of spatial distribution characteristics of different heavy metals in small-scale areas with a single farmland, which will help to comprehensively evaluate the function of spatial interpolation to identify spatial distribution information of heavy metals.

Abstract
Recent research indicates that electric vehicles can greatly ease the problem of environmental pollution caused by fossil fuels. Therefore, based on the development of electric vehicle market in the United States, this paper aims at finding an optimal approach for the conversion of fossil fuels to electricity, in elements of environment, economy, etc. Firstly, a station-building model about the amount of charging stations for the future requirements is established. According to the site-selecting principles, we set the station-building cost optimization model to forecast the number of electric vehicle developments in the next decade. Secondly, we build an optimization model and a logistic model to draw a conclusion that after the emergence of the new technology, there are more charging stations than before. Moreover, the proportion of electric vehicles has reached 100% in advance of five years ahead of the original forecast, which speeds up the construction of charging stations. Lastly, we suggest a series of new energy development plans on account of the serious pollution under the domestic environment.

Abstract
A weak signal processing method is used to distinguish the defect signal while signal-to-noise ratio is small, and the application in cable non-destructive testing so that can find the tiny defects in the cables. For the signal noise obeys the normal distribution in time domain which is symmetrically distributed on both sides of the real value. The signal noise could cancel each other after accumulating. while the real signal does not obey the normal distribution and could be amplified after time accumulating. A weak signal processing method is designed to collect weak signals multiple times under timing control, and accumulate the collected signal sequence strictly according to the time line. The accumulation of weak signals could effectively amplify the real signal without amplifying the noise, so that the weak signal generated by the tiny defects could be clearly distinguished. The application of weak signal processing method could greatly improve the accuracy of cable non-destructive testing.

Abstract
The numerical simulation of coal char combustion process can quickly obtain the combustion characteristics of char. It has guiding significance for the design and operation industrial boilers. But during the numerical simulation, how to choose the appropriate kinetic parameters is a difficult problem. The values of combustion activation energy in previous literatures were different. This paper focused on the influence of activation energy on the simulation results of char combustion. The activation energies of 20 Chinese typical coals were measured by a two-step in-situ reaction analyzer. CBK (Carbon burnout kinetics) model was used to simulate char combustion process. Results showed that when activation energy varied greatly, the the predicted combustion rate and particle temperature were very different, especially in the later stage of char combustion.

Abstract
With the rapid development of social economy, the demand for urban transportation is increasing, and the energy consumption and greenhouse gas emission of urban transportation are also increasing year by year. In this situation, energy saving and emission reduction of transportation industry is imperative. This paper studies the evaluation of the low carbon development level of urban transportation system. Based on the research of domestic and foreign literatures and the characteristics of Qingdao, the urban low-carbon traffic evaluation index system is constructed, including transportation infrastructure, transportation services, resources and environment, and transportation policies and regulations. There are 16 evaluation indicators. The entropy weight method is used to determine the weight value of the evaluation index, and then the gray correlation model is used for evaluation. Taking Qingdao as an example, the empirical analysis shows that in recent years, the low-carbon traffic level in Qingdao is constantly changing. At the same time, the correlation degree of each index is analyzed to find out the crux that hinders the development of low-carbon urban transportation.

Published: August 2019

Abstract
In order to avoid battery over-charges and over-discharges and improve the battery pack capacity, a passive equalization controller based on fuzzy logic control (FLC) is proposed to reduce the impact on inconsistency in manufacture and use processes of battery pack. A cell’s state of charge (SOC) difference and its temperature is chosen as the FLC’s input and the balance current is chosen as the FLC’s output. The advantage of this FLC is can reach a larger balancing current and control the batteries temperature at the same time compare with average SOC controller and switch controller. Simulation results show that the equalization strategy based on FLC can achieve battery pack balance in a shorter time in a lower finish temperature. This equalization strategy can provide battery management system (BMS) designer a higher performance control strategy on the basis of the existing hardware platform.

Published: August 2019

Abstract
As an unconventional power supply for on-line monitoring equipment, how to arrange the electric field energy harvesting device at the tower side and ensure its structural reliability in typhoon weather is worth further discussion. From the point of view of installation practicability, this paper adopts magnetic suction device, taking into account the T-shaped and circular cross-sections and modeling them. Through fluid-solid mechanical coupling simulation, the force and deformation of the device under different airflow velocities are obtained. The expression of minimum magnet suction which can ensure that the device is adsorbed stably at the side of the tower is deduced and used as the main index to measure the reliability of the structure of the device. Compared with the two kinds of device structures, the structure reliability of T-shaped collector is difficult to meet at higher wind speed, while the cylindrical collector is more reliable even when the wind speed gets high enough.

Published: August 2019

Abstract
Aiming at the problem of fast load recovery after power system blackout, an intelligent optimization strategy of load recovery based on grid partition is proposed. An optimal regionalization strategy for system recovery after major blackouts is proposed. In the optimization model, factors such as charging reactive power of overhead lines for generator recovery and closing times of lines for load recovery are taken into account. After optimizing the large-scale system partition, a unified load recovery optimization model considering network reconfiguration factors is established for each partition to realize the parallel load recovery of each partition. Aiming at the optimization model proposed above, the load recovery optimization problem based on power grid partition is solved by combining traditional graph theory and genetic algorithm. In the solution, the genetic algorithm is improved, and aiming at a large number of infeasible problems arising from the application of genetic algorithm, a method of random load rejection and shortest path repair strategy is proposed, which further improves the optimization efficiency and global optimization ability of the algorithm. The correctness and effectiveness of the proposed model and method are verified by simulation analysis of IEEE30-bus system.
