Published: June 2020

Abstract
In order to identify the relationship between dynamic plantar pressure information and hallux valgus, this paper proposes a CNN model to achieve a gait detection method based on plantar pressure. The plantar pressure data during walking convert into an image, and then the convolution neural network model in deep learning is used. Given enough input image data and expected classification results. By changing the parameters of CNN, the relationship between plantar pressure image and hallux valgus was established. Then final classification model is obtained. The result shows that the accuracy of the proposed CNN model for the diagnosis of hallux valgus achieve 90.56%, which can be used as a clinical assistant method for the diagnosis of hallux valgus. The experimental results verify the validity of the model.

AbstractIn recent years, with the rapid development of big data technology, users are more and more inclined to solve the problems of large amount of data and complex business scenarios with big data platform. When the system is faced with the scene of data hotspot and frequent data modification, it will produce a lot of useless data and cause data hotspot problems, which make a lot of access to the level of disk storage. Unreasonable data allocation of HFile will affect I/O performance and reduce system availability. This thesis proposes a comparison strategy based hot data. According to the frequency of data access, this stategy change the selection method of merging subsequence of Exploring Compaction Policy, so as to achieve a more suitable effect for hot data query business.

Abstract
The resettlement evaluation system for the recent flood control projects in the lower Yellow River consists of many economic indicators, social indicators, resource indicators and environmental indicators. Although the design of quantitative indicators is the main one, many of them are still used in order to better reflect the evaluation objectives. Qualitative and fuzzy indicators, traditional methods and means have been difficult to be competent in the comprehensive analysis of multi-factor and multi-level in the production and living system of immigrants. Yaahp software, based on the basic research method of AHP, constructs a hierarchical structure model, and assigns weights and calculations to post-immigration evaluation indicators.

Authors: Li Xia , Jin Xin , Guo Pan 
Published: June 2020

Abstract
The water-bearing system in the karst area is complex and changeable. Water in the water-bearing medium has the characteristics of coexistence of fissure flow and pipeline flow, coexistence of laminar and turbulent flow, coexistence of linear and nonlinear flow, coexistence of continuous flow and isolated water body. In areas where economic development is relatively backward, most areas lack data or no data. Based on the characteristics of the karst area in the southwest, this paper proposes a thinking evolution algorithm to optimize the gray neural network model. This method improves the optimization ability of runoff prediction models and effectively overcomes human neural network learning. The speed is slow and there are inherent shortcomings of local minima. After studying the daily flow forecast of Zhenlong Station, it is shown that the relative error of the prediction is small and can be effectively used for short-term runoff prediction.

Published: June 2020

Abstract
The key to agricultural modernization and environmental protection and green development depends on the progress of agricultural science and technology and the cultivation of new professional farmers. The cultivation of new professional farmers is the reality and future of modern green agriculture. The 19th National Congress of the Communist Party of China proposed a strategy for rural revitalization, which is the general plan for the work of “agriculture, rural areas and farmers” in the new period. Vigorously cultivating new-type professional farmers is a basic requirement for implementing the strategy of promoting agriculture through science and education and realizing agriculture and rural modernization. This article takes Jilin Province as a case, and on the basis of combing related research results, referring to the analytic hierarchy process and multiple regression analysis, analyses the causes of the formation of new professional farmers from multiple perspectives, and then analyses Jilin under the strategy of green agriculture through science and education The logical path for the cultivation of new-type professional farmers in the province proposes to adhere to the road of cultivation of new-type professional farmers that is “endogenous-led and exogenous-driven”.

Authors: Wang Xiaowei , Fu Tieqiang , Wang Chuanqi , Ling Jian 
Published: June 2020

Abstract
In this paper, the engine-in-the-loop (EIL) method was used to study the fuel consumption and emission characteristics of heavy-duty trucks at China Automotive Test Cycle (CHTC-HT) and world transient vehicle cycle (C-WTVC) on an engine test bed. The result of the vehicle speed followability shows that the difference between the actual vehicle speed and the target vehicle speed is within ±2 km/h, indicating that the vehicle cycle can be well reproduced on the engine test bed by EIL method. The consistency results of fuel consumption and emissions indicate that the fuel consumption error is 0.89%, the NOx error is 1.02%, and the particle number (PN) error is 5.04%. For this vehicle, the fuel consumption per 100 kilometers at CHTC-HT is 21.33L, which is 2% higher than that of C-WTVC; while NOx emissions of CHTC-HT are 59.2% higher than that of C-WTVC. It is more difficult for enterprises to meet the fuel consumption and NOx emission standards under China Automotive Test Cycle.

A method of RCS Sequence extraction based on CAC + EMD
Authors: Mao Nanping , Su Yan , Pan Gaofeng , Liu Guoqing , Sun Xiaodong 
Published: June 2020

Abstract
When the spatial object possesses the periodic motion, an obvious periodic phenomenon can be produced by its RCS sequence. Some methods such as Fast Fourier Transform Algorithm (FFT) and Circular Autocorrelation Function (CACF) can be used to judge the existence as well as the extraction of the sequence’s periodicity. Autocorrelation Function, Average Magnitude Difference Function (AMDF) and their combined transformation are essentially estimated by the correlation of their periodic signal. More than two periods of observation time is needed for accurate estimate. Furthermore, the requirement of the date rate is high and. Furthermore, such methods always accompanied by the errors of frequency multiplication and frequency division. In this paper, a periodic discriminant and estimation method combining cyclic autocorrelation and empirical mode decomposition is proposed. The periodicity of the original signal can be enhanced by the cyclic autocorrelation (CAC), and the signal component with the relatively complete periodicity can be obtained by the empirical mode decomposition (EMD). The periodic estimation of the measured data showed that the period estimated by CAC +EMD is more stable. In addition, this method is also effective in extracting the signal period with the weaker periodic phenomenon. In this paper, a periodic discriminant and estimation method combining cyclic autocorrelation (CAC) and empirical mode decomposition (EMD) is proposed (CAC+EMD), and a comprehensive comparison with the Single method is made, both CAC and CAC+EMD can extract the stable signal’s period effectively. With the gradual increase of noise discriminant effect of CAC+EMD on signal period is much better than CAC. Because CAC does not have the ability to process the non-stationary signal, so this method has a poor discriminant effect on signal period. As for the discriminant effect of CAC+EMD, there is no difference between stable signal and non-stationary signal.

The paper analyzes the operation stability of bag-type dust removal system through mathematical model, looks for the balance between people’s environmental requirements and garbage incineration, and proposes relevant monitoring schemes to the government, ultimately seeking to improve the stability of dust removal system. In this paper, the direct proportional relationship between the stability and the concentration difference of the bag dedusting system is obtained. It is shown that the dust concentration in the air decreases after the bag is replaced compared with that before the bag is replaced, and some feasible suggestions for environmental monitoring are put forward according to the model conclusion.
