Authors: Lu Jiahao 
Published: March 2021

Abstract
With the development of society, the progress of science and technology, the level of computer has been improved. Digital imaging technology has also achieved unprecedented development. The most commonly used digital cameras are Charge-coupled device (CCD) and Complementary Metal Oxide Semiconductor (CMOS) image sensors. Bayer filters are often used to help sensors capture color information. However, only one component can be achieved per pixel. Full-color images must be obtained by color interpolation. Therefore, the color interpolation algorithm has attracted the attention of the academic community. In this paper, three classical color interpolation algorithms- Bilinear interpolation algorithm, COK Algorithm, Gradient Interpolation Algorithm- are compared and studied. The Optimal Algorithm is selected by comparing false color, noise and color moire fringe. After comparison, it is found that the three basic algorithms will have color moire fringes appear. But the gradient interpolation algorithm has the least moire fringe and noise. COK Algorithm, second of all. But the COK Algorithm has color overflows.

Abstract
With the advancement of the construction of the China southern regional frequency regulation auxiliary service market, the calculation method of the AGC performance index of the generator set needs to be further optimized. To this end, an optimization scheme for calculating the AGC performance index of generator sets that is suitable for the China southern regional frequency regulation auxiliary service market is proposed. First, the demand for AGC unit participation in the frequency regulation market is analyzed, and a model for AGC unit participation in the frequency regulation market is established. Through theoretical analysis and data comparison, it is shown that the traditional calculation method of AGC frequency modulation performance index is not suitable for the calculation of AGC performance of FM market units. Aiming at the key content of the frequency modulation market for the AGC performance requirements of the unit, a suitable calculation method is proposed. Finally, the actual case that illustrates the applicability of the index calculation method in this paper is analyzed.

Authors: Zhang Longteng , Sun Yi 
Published: March 2021

Abstract
In order to improve climbing performance of the robot in complex environments, the wheeled-legged mechanism is gradually being widely used. In this paper, we use computer-aided modeling technology to design a 2-DOF ePaddle-based robot of high step-climbing capacity. Climbing strategies of the robot under the circle-wheeled (CW) mode and active-paddle-legged (APL) mode are carried out. We discuss determinants for success in climbing by establishing the climbing posture models. Simulation results processed with MATLAB tools reveal that paddle’s motion can significantly improve the climbing performance to avoid slipping. The experimental results verify the robot is capable of climbing over 300mm obstacle APL modes, which is 2.14 times the wheel radius.

Published: March 2021

Abstract
At present, there are various indoor positioning technologies, most of which need to establish a base station to achieve positioning. The cost of establishing a base station is high, and sometimes it is greatly disturbed by the influence of buildings. The indoor positioning accuracy without base station is not high, and the matching time is also long.In order to solve these problems, the experimental group first adopted magnetism as the primary measurement tool for indoor navigation and positioning. In addition, by using the Kriging method, the high precision magnetic reference map is established in the server to improve the positioning accuracy, and the inertial navigation technology is used to shorten the matching time. This paper mainly discusses the establishment of the Kriging method in the magnetic reference map and the localization matching algorithm of the inertial navigation auxiliary magnetic navigation. The experimental group verified and simulated the feasibility of this method, which can greatly improve the positioning accuracy and matching efficiency.

Abstract
This paper analyzes the players in the game of "crossing the desert", and puts forward the optimal customs clearance strategy to help the game players reach the destination within the specified time under the condition that the remaining funds are retained as much as possible. Firstly, the redundant paths are eliminated and the complete subgraph of the game map is drawn to improve the speed of computer optimization. Then, the multiple rules in the game are transformed into the constraints in the planning model, such as load constraint, remaining fund constraint, resource margin constraint and so on. By solving the model based on adjacency matrix and mixed integer programming, the rationality of the optimization strategy is verified by an example. The waiting model is used to decompose the number of players and consider different space and time to maximize the revenue of a mine as much as possible, while reducing the basic consumption of latecomers in a certain area and the consumption of resources purchased in the same village.

Published: March 2021

Abstract
Implicit sentiment analysis is an important part of sentiment computing, especially sentiment analysis based on deep learning has become a research hotspot in recent years. In this paper, convolutional neural networks are used to extract text features, combined with long-term and short-term memory network (LSTM) structure to extract context information, and add attention mechanism to the network to construct a new hybrid neural network model to achieve implicit emotion for text analysis. The hybrid neural network model extracts more meaningful sentence semantic and structural hidden features from the word-level and sentence-level hierarchies, respectively, and pays attention to the features with a large emotional contribution rate through the attention mechanism. The classification accuracy rate of the model on the public implicit sentiment dataset has reached 77%. The research of implicit sentiment analysis can improve the effect of text sentiment analysis more comprehensively, and further promote the application of text sentiment analysis in the fields of knowledge embedding, text representation learning, user modeling and natural language.

Authors: Hu Zhiqing , Zhang Yuheng , Guo Liming 
Published: March 2021

Abstract
In order to study the effects of grain orientation on thread rolling deformation, the mechanical performance was analyzed from a microscopic perspective. The Voronoi method was employed to establish a polycrystalline model and a user-defined material subroutine (UMAT) was adopted. Meanwhile the crystal plasticity finite element method (CPFEM) was used to simulate the deformation behavior of the grain on thread rolling process. The simulation results show that the deformation degree of the grain is different due to the different initial grain orientation and the representative element strain curve is more accurate after homogenization. It is also indicated that the initially activated slip systems cause the movement of the other slip systems. By analyzing the rotation of the grain orientation and the evolution of the texture through the pole figure, it can be seen the CPFEM results show high consistency with the test results of the electron back scatter diffraction (EBSD).
