摘要：
In transportation fields, safety, efficiency, and reliability of engines are primary concerns. Remaining useful life (RUL) estimation technology is used to assess the current health status and make effective maintenance plans for engines. How to estimate RUL accurately to increasing the reliability and safety of systems is a challenge issue. However, the existing estimation methods focus on single size sequence. To address it, this paper proposes a remaining useful life prediction model based on hybrid long-short sequences for engines. For long sequence, long shortterm memory neural network is used to predict RUL by mining smoothed data potential association rules. For short sequence, time window is used to determine the size of short-term sequence, and a direct relation between engine state and RUL is modeled by gradient boosting regression. Finally, back propagation neural network is used to analyze the RUL results of long sequence and short sequence to obtain hybrid sequence prediction result. The proposed model is implemented in a turbofan engine degradation dataset, and the experimental result demonstrate the proposed model is better than other in terms of accuracy.
摘要：

Medical image storage and analysis are progressively becoming cloud-based, providing the preconditions for the efficient cooperation of remote diagnostics and the full sharing of research resources. However, the frequent medical data breach events have greatly infringed on the privacy of users and brought about huge social losses. Therefore, how to strengthen medical images security and privacy protection during transmission, storage and use is very urgent. In this paper, the security requirements of medical images in cloud computing are analyzed. And a survey is introduced focusing on the development status of medical images security techniques in recent 5 years. The open issues of medical image security are also analyzed in this paper, which point out the possible directions for future research.

摘要：
The wood processing industry is an important industry which affects the national economy and social development. The data envelopment analysis model (DEA) is a quantitative evaluation method for studying industrial efficiency. In this paper, the wood processing industry of 8 provinces in southern China is taken as the study object, and the efficiency of each province in 2006 to 2015 was measured and calculated with the DEA method, and the efficiency changes, technological changes and Malmquist index were analyzed dynamically. The empirical results show that there is a widening gap in the efficiency of wood processing industry of the 8 provinces, and the technological progress has shown a lag in the promotion of wood processing industry. According to the research conclusion, along with the situation of domestic and foreign wood processing industry development, the government must introduce relevant policies to strengthen the construction of the wood processing industry technology innovation policy system and the industrial coordinated development system.

摘要：
With the abundance of spectral information and texture information of remote sensing images, the feature variables applicable to land cover classification also increase. But the high-dimensional features will deteriorate the classifier performance. In this paper, an improved selection method was proposed by considering separability and redundancy between feature variables. The study area - You County was divided into eight land cover types based on the SPOT-5 remote sensing image in 2009 combined with the continuous inventory data of forest resources during the same period. A total of 3,921 sample plots containing classification information were selected, of which 2/3 were used as training data, 1/3 as testing data. Waveband operations and texture extraction were performed on the images and a total of four bands information, eight texture factors, and nine vegetation indices were extracted as candidate feature variables subset. Calculate the weighted average of the Jeffries-Matusita (JM) distance between different classes of each feature variable, as the measure of class separability, and select the variable ordered first. Then calculate the PEARSON correlation coefficient between the remaining variables and the selected variables as the measure of variables redundancy. The ratio of separability and redundancy is referred to as the improved JM distance, which is successively substituted into the Bayesian classifier in descending order. The results show that (1) From the JM distance, the spectral features are more suitable for the land cover classification in the study area than the texture features. (2) The overall classification accuracy can be improved through the feature variables selected by improved JM distance. (3) The number of feature variables using the improved JM distance to achieve stable classification accuracy is far less than traditional JM distance, which effectively reduce feature dimensions. Therefore, the improved selection method proposed in this paper not only retains the class separability but also avoids the information redundancy, and can effectively select the feature variables.

摘要：
The permanent magnet synchronous machines (PMSMs) have been used in a variety of different industrial applications. The transient parameters of the PMSM determine the safe operation and stability of the whole system. This paper introduces Hilbert-Huang transform (HHT) to identify the transient parameters of the PMSM. First of all, based on three-phase sudden short-circuit current, the DC and AC components from the transient current are extracted by using empirical mode decomposition (EMD). Then, by performing curve fitting on the envelope of DC and AC components separately, the transient parameters of the PMSM are obtained. Finally, the current waveform based on identification parameters is compared with the finite element (FE) current waveform to verify the effectiveness of the identification method.

摘要：
The obtained precisely high frequency information is the key of single-frame image super-resolution reconstruction by using two-dimensional wavelet. Because the bicubic interpolation of high frequency components decomposed by wavelet will introduce noise, it will affect reconstruction effect. An improved algorithm using Fourier transform and zero-padding resampling instead of bicubic interpolation is proposed in this paper. The advantage of frequency domain interpolation is obtained by using Fourier transform and zero-padding resampling. And high frequency components obtained by wavelet decomposition of the original image can be interpolated optimally without introducing noise, which makes the high frequency details more precise in the reconstruction process. The experimental results show that the improved algorithm is superior to the traditional two-dimensional wavelet reconstruction algorithm, which can be applied to the single-frame remote sensing image super-resolution reconstruction.

摘要：
This paper proposes the method of analog circuit fault diagnosis based on high-order cumulants combined with Information Fusion. It is to extract the original voltage and current signals from output terminal of the circuit under test, to determine their kurtosis and skewness as fault eigenvectors, and to import them into improved BP neural network for fault diagnosis. As for construction of fault eigenvectors, high-order cumulants technique, compared to Principal Component Analysis (PCA) which is based on second order statistics, pays more attention to information neglected by PCA. After Information Fusion is employed to integrate voltage with current as fault eigenvectors, it makes eigenvectors show relatively comprehensive fault information. Diagnosis examples further verify that fault eigenvectors gained in this way have higher recognition rate and diagnosis accuracy.
摘要：
The purpose of this study is to load different formats of tile files through the tile Pyramid model in the Android platform, so as to optimize the storage mode according to the use scene. To compare the compression rate, loading time, loading speed, loading speed, portability and convenience under the given experimental data, according to the four commonly used storage modes (scattered files, ZIP files, SQLite database files and tile flow collection files). The experimental results show that loading SQLite database files loading tiles, the average time consuming 301ms, the average memory consumption 25.8MB, the overall performance is the best, is the preferred format for the Android version of the GIS grid data storage. At the same time, the test results show that the comprehensive advantage of the custom tile flow collection file is significant. If the storage structure of the file is further optimized, it can completely replace the SQLite storage mode and no longer be limited to the limitation of the database itself.

摘要：
The subdomain model for analytical calculation of magnetic field is widely developed to predict electromagnetic performance in permanent magnet ( PM) machines. Based on the principle of the mutual flux through the stator windings due to step-skewed PMs identical to that from equivalent non-skewed PMs, a 2D subdomain model of surface-mounted PM machines accounting for step-skewed magnets is proposed. By resolving the analytical expressions of the equivalent PMs subdomain, the 3D problem of step-skewed magnets along axis is simplified to a 2D problem, which saves the computational resources and improves the efficiency. The 2D multislice finite-element analysis confirms accuracy of the analytical method.

摘要：
The subdomain technique has been widely used to predict electromagnetic performance in permanent-magnet (PM) machines. Due to the high accuracy of magnetic field distribution prediction by subdomain technique, a simple method for electromagnetic performance calculation in surface-mounted PM machines with skewing is proposed. By taking the machine with step-skewed magnets as a combination of multi-machines operating with different rotor positions at the same instant, the influence of the axial magnet segments can be considered in 2D subdomain model of surface-mounted PM machines. Based on the magnetic field analytical solution, the cogging torque, back-EMF and electromagnetic torque is calculated, and the 2D multislice finite-element analysis confirms accuracy of the analytical method.

摘要：
The urban heat island (UHI) phenomenon has been studied extensively. There are also urban cool island bodies, such as water and green spaces, but relatively fewer reports explored the urban cool island (UCI) phenomenon. The goal of this work is to find the effective urban channel water pattern to bring down the temperature in summer. The relevant elements of water cooling effect were identified by Dalton's law of evaporation, and "land's cool island region" was put forward to indicate the cool island's effect on exploitable land. The landsat+Thermal Infrared Sensor (TIRS) date and Envi softwear were applied to obtain the land surface temperature and the spatial characters. Analysis results indicated that with the increase of water's width, the range of "land's cool island region" is amplified, but the efficiency of unit width water's land's cool island region is decreasing. This work puts forward "narrow section, dense water network" as an urban water environment planning layout pattern based on the efficiency of unit width water.
摘要：
This paper considers the problem of scheduling multiple two-stage flowshops that minimizes the makespan, where the number of flowshops is part of the input. We study the relationship between the problem and the classical makespan problem. We prove that if there exists an \(\alpha \)-approximation algorithm for the makespan problem, then for the multiple two-stage flowshop scheduling problem, we can construct a \(2 \alpha \)-approximation algorithm for the general case, and \((\alpha + 1/2)\)-approximation algorithms for two restricted cases. As a result, we get a \((2 + \epsilon )\)-approximation algorithm for the general case and a \((1.5 + \epsilon )\)-approximation algorithm for the two restricted cases, which significantly improve the previous approximation ratios 2.6 and 11/6, respectively.

摘要：
Multi-source remote sensing data is rarely used for the comprehensive assessment of land ecologic environment quality. In this study, a digital environmental model was proposed with the inversion algorithm of land and environmental factors based on the multi-source remote sensing data, and a comprehensive index (Ecoindex) was applied to reconstruct and predict the land environment quality of the Dongting Lake Area to assess the effect of human activities on the environment. The main finding was that with the decrease of Grade. and Grade. quality had a decreasing tendency in the lake area, mostly in suburbs and wetlands. Atmospheric water vapour, land use intensity, surface temperature, vegetation coverage, and soil water content were the main driving factors. The cause of degradation was the interference of multi-factor combinations, which led to positive and negative environmental agglomeration effects. Positive agglomeration, such as increased rainfall and vegetation coverage and reduced land use intensity, could increase environmental quality, while negative agglomeration resulted in the opposite. Therefore, reasonable ecological restoration measures should be beneficial to limit the negative effects and decreasing tendency, improve the land ecological environment quality and provide references for macroscopic planning by the government.
