Published: December 2019

Abstract
With the improvement of ecological environment and the expansion of the scale of power grid construction, “bird damage” has brought great hidden dangers to the safe and stable operation of power grid. On the one hand, human awareness of natural protection has been enhanced, the speed of bird reproduction has been accelerated, and the threat of birds to the line has gradually increased. On the other hand, bird damage prevention measures were not considered in the early design of power grid. Bird damage was prevalent in operation. After bird damage, the response measures were not timely, the treatment efficiency was low, and the number of line trips and non-outages increased. Especially in some backward areas, once the power grid loses contact with the provincial network, it will cause large-scale blackouts in the county (township) often occur, which directly affects the safe, stable and reliable operation of the power grid. It is urgent to prevent bird damage on the line.

Published: December 2019

Abstract
Aiming at the problem that the tumor is difficult to be accurately segmented due to noise and edge discontinuity in the chest breast MRI image, a medical image segmentation algorithm based on gradient edge detection and control marked watershed is proposed. Firstly, the mathematical morphology reconstruction filter is used to remove the small texture and noise of the MRI image of the breast tumor, and then the local minimum associated with the object is extracted from the low-frequency components of the gradient image, and they are formed into a binary marker image; The reconstructive technique is forced to be the local minimum of the original gradient image, the adaptive correction of the gradient image is realized, and finally the watershed segmentation is performed. The experimental results show that the algorithm can automatically and quickly extract the breast tumor region in the series of MRI images and realize the automatic segmentation of the region of interest in the medical image.

Authors: Chen Changkun , Xu Tong , Zhao Dongyue , Lei Peng 
Published: December 2019

Abstract
The serious consequences of transmission lines tripping fault induced by wildfires (TLTFIW) urges scholars to pay more attention to the safe operation of transmission lines. To illustrate the evolution process of TLTFIW and quantitatively evaluate the occurrence probability of subsequent events, an algorithm used for TLTFIW is proposed by using ETA, FTA and fuzzy number theory in this paper. The evolution process of TLTFIW is simulated according to ETA, which is divided into six stage including wildfires occurring, early wildfires early-monitoring, Wildfires extinguishing, Wildfires spreading, transmission lines tripping, and re-closing failure. In addition, the reason of the subsequent events in the evolution process are analysed by FTA, and the trapezoidal fuzzy theory is employed to calculate the probability of each events. Finally, based on the evaluation results, suggestions are provided for the evolution links with greater risks. Furthermore, transmission lines located in Xiangxi is introduced to present an application of the algorithm.

Authors: Zhang Jialin 
Published: December 2019

Abstract
The way in which science and technology innovation center drives regional innovation capabilities depends on the spillover and radiation of innovation resources. Starting from the connotation of the science and technology innovation center, combined with the electric field theory in physics, the innovative radiation field with the science and technology innovation center as the field source is constructed, and the field source intensity is quantified from four aspects: innovation resources, innovation input, innovation achievements and innovation carrier. Taking the Shanghai science and technology innovation center as the research object, and using 2014 as the base year, the innovative radiation effects of the Yangtze River Delta urban agglomeration before and after construction was measured. The research shows that the radiation intensity of Shanghai has increased significantly since the establishment of the science and technology innovation center, but the overall radiation pattern has changed little and there is still a lot of room for improvement. Finally, the countermeasures for enhancing the innovative radiation effect of the Shanghai science and technology innovation center are proposed.

Abstract
With the development of social economy, the demand for transportation is also growing. High-speed railway has become an important part of the transportation system. It is not only an inevitable requirement for the development of the national economy, but also an important support for the implementation of the national strategy. Therefore, whether the high-speed train can operate smoothly and safely is related to the passenger’s life and health and property safety. This requires accurate control of the automatic operation of the high-speed train during the driving process. At present, China’s research on the automatic operation control of high-speed trains is still in its infancy. The problems of traction and brake system actuator failures that may occur during long-term running of trains can be solved by artificial neural network-based modeling methods. The automatic operation control algorithm of high-speed train running process is established. The self-correcting control strategy based on artificial neural network is used to realize the speed tracking of high-speed trains. The high-speed train visual simulation system is established by virtual reality technology and verified on the artificial neural network platform.

Authors: Cao Yang , Jia Fangxiu , Zhang Qing 
Published: December 2019

Abstract
Position sensitive detectors (PSDs) have been spotlighted as effective position sensors in terminal navigation of laser semi-active guided weapons. However, it remains an ongoing challenge to improve linearity, especially under impulsive excitation. In this paper, the response of the PSD for continuous light excitation is proposed for the first time to correct the PSD response results under pulsive excitation. After establishing the mathematical model of the two-dimensional PSD, the response results under different illumination excitation are simulated and analysed, which theoretically proves the feasibility of the correction method in this paper. Finally, the experiment is carried out with PSD (S5990-01). The results reveal that the distortion degree of the PSD response results is more obvious with the decrease of pulse width under pulse illumination. The impulse response result can be linearly mapped into a steady-state response result with the range of slope values being 0.403∼0.614 and intercept values being -0.098∼0.106.

Abstract
In the performance test of mesh network routing protocol, it is found that BATMAN. Adv routing protocol has better performance than the existing multi-hop routing protocol, but it also has the defects of poor routing convergence and slow response to network topology changes. Based on the detailed analysis of BATMAN. Adv routing protocol, this paper proposes an improved method. First, the statistical method of OGM package was redesigned, the cumulative sliding window method is used to improve the influence of the latest serial number of OGM, and the calculation method of TQ value is changed from average accumulation to weighted accumulation to further improve the influence of the latest TQ value. At the same time, an improved mechanism is proposed in order to solve the problem of link blocking caused by sudden node failure. Finally, through simulation experiments, the performance of the packet delivery rate and end-to-end delay of the three routing protocols in two different scenarios is compared. It shows that the improved protocol can effectively improve the packet delivery rate, reduce the average end-to-end delay, and improve the network performance.
