Azimuth super-resolution is generally realized by real beam scanning deconvolution and array antenna super-resolution algorithms, especially by using amplitude envelope or phase information. Aiming at the situation that echo information is not fully utilized, this paper proposes a forward looking imaging method of array radar scanning based on compressed sensing, combining the real beam scanning by transmitter and the echo receiving by array antenna. Under the condition of sparse scene, the range dimension super-resolution is achieved by pulse compression, and the azimuth direction complex observation matrix is constructed based on the array antenna echo model, and the super-resolution is achieved by improved L1 norm smoothing approximation algorithm. The 2d super-resolution imaging simulation results show that the proposed method can effectively improve the performance.

As the core key equipment of the power system, power transformers transmit AC power to the power grid. They are an indispensable part of long-distance power transmission and play a vital role in the safe, stable and reliable operation of the power grid. In order to perform on-line detection of partial discharge of transformers and classify faults, this paper proposes an intelligent spectrum monitoring method based on power transformers. This article first designs a power transformer electromagnetic spectrum signal acquisition system, and then performs data preprocessing on the collected power transformer spectrum data using wavelet transform. Wavelet transform can check the frequency domain characteristics of the local time domain process and the time domain characteristics of the local frequency domain process. After that, this paper use a convolutional neural network model, which is a residual network. The model makes a reference to the input of each layer and learns to form a residual function instead of learning some functions without reference. This residual function is easier to optimize and can greatly deepen the number of network layers, Input the preprocessed I/Q data into the network model for fault classification of power transformers. Based on the above, the frequency spectrum of the power transformer can be effectively monitored and fault detection can be performed. Experimental results show that our method can classify power transformer faults with an accuracy rate of 98.4%, and has a higher accuracy rate than traditional transformer fault detection techniques.

The Transformer has achieved tremendous success in computer vision, natural language processing, and graph representation learning. However, the transformer cannot effectively encode the topology information of the graph into the model, while it is the advantage of the graph convolution network (GCN). Therefore, we propose a model GTGC combining transformer and GCN for graph classification tasks. To this end, we take the result of graph data passing through multi-head self-attention and feed-forward blocks as the input of the graph convolution module. By increasing the number of neighbors for each node’s feature matrix, the nodes with more neighbors are more important in the attention mechanism. We validate the validity of the model on multiple data sets, including social network datasets and bioinformatics datasets. Experimental results demonstrate that our model achieves advanced accuracy

Energy is an important component of a country's economic development, and power resources are also an indispensable energy in people's production and life. There is also a large amount of energy waste caused by low lighting management efficiency in universities. This paper has designed a new intelligent light control system based on IPV6 network, using the network camera installed in the classroom to transfer the classroom image to the server through the IPV6 network. Through image processing, the data in the classroom is obtained and sent to the light control module to control the switch of the classroom light, supplemented by the manual control module, clock control module and photosensitive module, etc., and finally realize the intelligent management of the classroom lighting. Through the test of the intelligent light control system based on IPv6 network, the system has high sensitivity to moving images. For classrooms with different lighting conditions, large changes in pedestrian density and large randomness of use time, the control of the system can achieve accurate regulation. The whole system has low cost and high reliability. It is very suitable for classroom lighting control in teaching units and has good application value.

Using remote sensing technology to extract urban impervious surface information has a wide range and high efficiency and plays an essential role in monitoring urban expansion and urban ecological environment change. Generally speaking, if a place is an impervious surface, its surface temperature would be higher. The traditional impervious surface information extraction is based on a single data source and a single-phase remote sensing image, and the error of the extraction results is large. Based on the multi-temporal Sentinel-2 remote sensing image and LJ1-01 nighttime light data in 2018, the impervious surface information was extracted in the main urban area of Qingdao. Combined with the surface temperature retrieved from Landsat OLI/TIRS data, the spatial relationship between the urban heat island effect and impervious surface coverage was analyzed. The results show that multi-temporal and multi-source data can accurately extract urban impervious surface information, and some regions between impervious surface coverage and urban heat island effect cannot show spatial correlation.

Plotting system refers to a software system that can draw a series of vector symbols, typesetting, saving, reading and so on. The traditional plotting system uses key and mouse operation to draw. With the development of electronic equipment touch screen in recent years, the traditional menu selection is not convenient enough, but the way of using hand-painted sketch and recognized by the system is more natural and fast. Traditional image recognition methods need huge amount of data for training, but the vector symbol set in the plotting system is not a common symbol set, so it is difficult to obtain a large amount of data. Therefore, this paper proposes a β-TCVAE-Attention hand-drawn plot recognition method which can obtain better recognition accuracy in the case of small samples. The model first uses the Image dataset to pre-train βTCVAE, and then uses the small sample data of the plot sketch to input the β-TCVAE encoder to obtain the sketch features. After the sketch features are enhanced with the attention module, they are input into the Softmax classifier based on cosine similarity. The neural network is fine-tuned according to the classification results of the classifier. Finally, when using network prediction, input the support set and query graph into the network for classification. In this paper, a 20-way-5- shot plotting data set is collected for experiment, and the experiment proves that the model has certain accuracy.

Speech enhancement technology has been applied to many research fields of speech signal processing, such as speech coding, speech recognition, noise suppression and so on. However, in practical applications, there is always noise in the environment, voice in the transmission, to avoid noise interference, and the quality of the environment noise has different effects on the quality of the speech signal. Therefore, speech enhancement algorithm can realize the original clean speech from noisy speech signal. The traditional single microphone in the process of dealing with environmental noise, the received target signal and noise signals are often overlapping in the time and frequency spectrum. In view of the traditional method, using microphone array can improve the quality of voice communication, and can make full use of the time and space information of speech signal. Therefore, the use of a microphone array can overcome the shortcomings of a single microphone.

With the advent of the 5G era, people's requirements for communication quality are gradually increasing. Compared with the previous centimetre wave antenna, the millimeter wave antenna has a wider bandwidth and ultra-high-speed with low latency. In present, the use rate of the millimetre wave frequency band is less, so there are few interference sources. In this respect, the reliability of millimeter wave communication is improved. Patch antennas have been widely used in recent years because of their small size and good integration with other circuit components. In the design of this article, we will use CST software to simulate a 5G millimeter wave microstrip line patch antenna.

Due to the characteristics of large volume, multiple types and fast speed of power grid data, traditional methods have been unable to process power big data. Therefore, this study proposes the information security terminal architecture of mobile Internet of Things in power industry based on big data analysis, and presents the architecture of the whole system. Based on the Yarn cluster computing system that supports Spark, Hadoop technology, wireless communication technology, Internet technology, sensing technology and so on are used to provide the solution of big data storage and terminal collection of the system, and the existing difficulties and problems are analyzed. The main difficulty of big data construction lies in that HadOOP platform itself is only one of the technical means to achieve big data platform. Therefore, the main difficulty of this paper is how to construct a more reasonable data organization mode and determine the source and organization form of associated data from the actual application requirements of the power industry, so as to truly mine as much value-added information as possible from the large database.

Bayesian network can effectively deal with uncertain reasoning and realize data statistical analysis, and it has been widely used in current power system research. Because of its strong logic and fast data processing, Bayesian networks have great advantages in solving the faults caused by the uncertainty and relevance of complex systems. The construction and operation and maintenance of the power Internet of Things are faced with various uncertainties. In order to improve the ability of the power Internet of things to deal with various uncertain and unexpected factors, a Bayesian network-based reliability evaluation model of the power Internet of things is established. This model integrates the level indicator reliability requirements of the perception layer, network layer, platform layer and application layer of the power Internet of Things, and establishes a Bayesian network node and network structure containing its threat factors. In addition, the Bayesian probability solution method is used to describe the reliability level, and quantitatively analyze the failure and accident consequences of the power Internet of Things. From this, it is possible to assess the emergency response level of the power Internet of Things to formulate corresponding risk response methods, to curb any power Internet of Things security incidents at the source in the future, and to increase the security construction and operation and maintenance of the power Internet of Things.

YOLOv3 is one of the target detection methods based on DNN, which has good performance in terms of speed and accuracy. However, with the gradual increase in application scenarios and the increasing demand for detection, the missed detection problem of YOLOv3 is deeply criticized. To further improve detection performance, we propose an improved model YOLOv3-A based on YOLOv3. Firstly, YOLOv3-A introduces channel and space two-dimensional attention modules in the feature extraction backbone network to achieve feature focusing on different dimensions, thereby reducing the missed detection rate. Then, in order to avoid network degradation, YOLOv3-A uses a residual module to replace the multi-layer convolutional layer at the rear of the feature extraction backbone network. Finally, YOLOv3-A introduces two different loss functions for positioning and confidence, respectively, using GIoU loss for bounding box positioning and Focal loss for confidence to improve model accuracy. On the PASCAL VOC data set, the mAP of YOLOv3-A is 59.13%, and the mAP of YOLOv3 is 50.92%.

With the advancement of technology and the updating of information, more people choose to watch movies on the Internet. In the world of brust data, users often encounter the difficulty of finding their favorite movies. Implementing the movie recommendation system of the media platform is one of the most effective ways to solve this problem. In order to avoid the imbalance of user data in the actual operation process, the content-based recommendation model is adopted in this research, aiming to find their similar variables in each movie, to calculate similarity index between each movie through the matrix and Pearson formula. The advantage of this method is that the potential interest of users for each movie can be discovered, and the probability of the movie being recommended will not be caused by the problem of the popularity of the movie.

With the outbreak of the Covid-19, people’s reliance on electronic devices has become more and more serious. Especially in the special period in present, the mode of online learning through electronic devices has been widely adopted by young students at different stages. There are various supports for electronic devices, but most of them can only be placed in a fixed position. Some display supports can be manually adjusted to a suitable position, which cannot provide more intelligent functions. Based on the current circumstances, by using computer software to build a 3D bracket model, and make it by 3D printer, with raspberry pi as the main control chip and stm32 as the system auxiliary chip, a set of intelligent display screen bracket based on IOT is developed. The smart bracket can independently adjust the position of the user and the screen, and can set auxiliary functions in real time according to needs, such as reminder of learning hours, sitting posture adjustment, voice interaction, etc. and can control core functions through the mobile terminal of the mobile phone. This paper aims to alleviate the problems of eye fatigue and high myopia rate caused by the improper posture of young people when using electronic display devices.

The task of Chinese named entity recognition (CNER) is closely related to Chinese word segmentation, because most Chinese entities are composed of words. The CNER model with words as the minimum input unit is called word based CNER model. However, wrong word segmentation will lead to wrong entity recognition results, so the CNER model with single word as input (char based) has gradually become the focus of research. Recently, many efforts have begun to integrate external word information to improve the performance of word based CNER model. And softlexicon are excellent word information fusion methods. When using softlexicon method for word fusion, too much matching word set information will be introduced, resulting in additional "noise" interference, resulting in entity recognition errors. Aiming at the problems of softlexicon method, this paper proposes a word information Selected-Softword-Concat method (SSC), which effectively solves the problem of "noise" in softlexicon method by introducing word segmentation information. The experimental results on four general CNER data sets show that compared with softlexicon method, the F1 value of the model constructed by SSC method is increased by 0.94, 0.92, 0.78 and 0.25 respectively, which effectively solves the "noise" problem of softlexicon.

The container terminals and carriers are regarded as a challenging wireless communication enviroment, caused by the metalic walls of container and the corners with the resulting multipath and shadow effect. Accurate propagation modeling of it is helpful for node deployment and channel estimation. However, existing researches mostly focus on obstacles on the macro-scale, and rarely analyze the small-scale propagation characteristics, such as the propagation characteristics along the gaps between containers. Thus there is also a lack of engineering practical path loss model. In this paper, we first study the propagation environment of the stacked containers. Then we propose a path loss model for gaps between containers based on geometric analysis. The proposed path loss model matches well with ground truth value.

This paper mainly studies the optimal cost planning of production enterprises in supply chain management. The research on this problem can effectively reduce the risk of enterprises in the procurement process, enable enterprises to obtain the maximum benefits with the lowest cost, and enhance the market competitiveness of enterprises. First of all, the data in Annex 1 are analyzed and preprocessed to extract three kinds of indicators: supply volume, stability and credit value, and then comprehensively evaluate the quality of suppliers from these three angles. Then the double-objective programming model is used to solve the problem, and the genetic algorithm, subjective weighting method, MATLAB programming calculation and SPSS statistical analysis are used to get the ordering plan and transfer plan in the next 24 weeks, which can meet the production demand and the lowest production cost at the same time. Combined with the premise that the enterprise has sufficient room for capacity improvement, the total supply of all suppliers calculated is the weekly capacity appreciation of the enterprise. At the same time, the order quantity is the supply quantity, so when making the ordering and transshipment plan, we only need to consider the economy of the transshipment plan, through the 0-1 programming model with the lowest loss rate as the objective function, get the raw material ordering plan and transfer plan of the enterprise in the next 24 weeks. Finally, the advantages and disadvantages of the model are analyzed and evaluated. on the basis of improving the shortcomings, it is concluded that the model can also be extended to the sales planning problems faced by enterprises and the scheme selection problems in life.

The torpedo car (TPC) plays a vital role in the safe transportation of molten iron in steel manufacturing. Due to its longterm operation in high-temperature environments and frequent use, it is prone to a variety of faults. However, traditional manual judgment methods are not effective in fault diagnosis and have low safety factors. Through engineering practice and data visualization analysis, it is found that the temperature data of the torpedo car have a strong time dependence and are closely related to the occurrence of its faults. Therefore, this paper selects the temperature data from the working status data of a torpedo car in a large steel plant. On the basis of effective data preprocessing and sample construction, the multilayer ATT-GRU network model based on the attention mechanism using timing features is proposed for its fault diagnosis. The model uses a multilayer GRU network to extract the temperature sequence characteristics of different time segments, and the attention mechanism is used to focus on the part of the input that contributes a greater amount to the fault diagnosis results, so as to improve the diagnostic effect of the model on the type of the torpedo car faults. Compared with traditional methods, experiments show that this method significantly improves the convergence speed of model training and diagnosis accuracy. It provides a friendly solution for real-time and accurate fault diagnosis of the torpedo car and other industrial equipment.

Fuzzing has become one of the most commonly used methods for exploiting software program vulnerabilities because of its ease of use and effectiveness. With the increasing complexity and importance of network services, fuzzing in parallel mode can greatly improve the efficiency of finding vulnerabilities. Typical representatives are Google's Clusterfuzz and the parallel mode of fuzzers such as AFL, Libfuzz. However, due to the lack of effective control in the process of mutating seeds in different fuzzing instances, the existing parallel fuzzing methods have problems such as high redundancy of generated test cases and low comprehensive coverage. In response to this problem, we proposes a parallel fuzzing method based on two-stage mutation. First, we use random mutations to perform fuzzing test within a period of time, divide the detected state space of the target program into independent state subspaces, and then distribute the corresponding tasks to each fuzzing instance, and use the same ordered mutation on each instance to ensure the generated test cases are lowredundant. We use this method to conduct experiments on the LAVA-M test set and open source software OpenJPEG. The experimental results show that it can improve the efficiency of fuzzing and find more crashes.

The application of 5G millimeter wave communication is becoming more and more widespread. This paper analyzes the rectangular patch antenna based on the transmission line model, and designs a mobile terminal antenna for 5G millimeter wave communications through CST software, which effectively reduces its size by using centre-side feed and embedded feed technology. The simulation results suggest that the central frequency of the antenna is 43GHz, the effective working frequency band covers 40-47GHz, the width of the band is 7GHz, the port reflection coefficient when it works at the central frequency is less than -20dB, the maximum gain is 5.451dB, and the antenna also has a good sense of direction and low loss. Furthermore, the design is quite flexible and simple in structure. Therefore, it is much likely that the antenna can be used for the future 5G millimeter wave communication terminal and the MIMO antenna element of the 5G communication base station.

C4 olefins play an important role in the production of chemical products and medicine, and ethanol is used as the raw material for the preparation of C4 olefins in this paper. the catalyst combination and temperature will have an effect on the selectivity of C4 olefins and the yield of C4 olefins. This paper mainly studies the optimal scheme of C4 olefin selectivity, which is solved by correlation analysis. In this paper, a correlation analysis model based on Pearson correlation coefficient was established to determine the selective linear regression of temperature to ethanol conversion and C4 olefins, which conformed to the first-order linear regression model. Then using SPSS software under different catalyst conditions, it is concluded that the conversion of ethanol at temperature and the selectivity of C4 olefins accord with the first linear relationship of positive convergence. Then, by making a scatter diagram, the changing trend of the selectivity of each product is determined, and a reasonable regression is carried out to determine the changing trend of the selectivity of each product with time. Then a control model based on the method of control variables was established. First, the data were preprocessed to separate different types of catalysts in the catalyst combination. The effects of Co loading, Co/SiO2 content and ethanol concentration on ethanol conversion and C4 olefin selectivity were removed by control variable method, and a partial correlation model was established to supplement and improve the control model based on control variable method. The effects of HAP content, the quartz sand content, Co/SiO2 and HAP loading ratio on ethanol conversion and C4 olefin selectivity were determined.

In this paper, the relationship between ethanol conversion, C4 olefin selectivity and temperature is studied. Firstly, the initial three-dimensional surface is drawn with catalyst combination and temperature as independent variables and ethanol conversion and C4 olefin selectivity as dependent variables. Then, in order to more accurately obtain the change rate of dependent variables, take the catalyst combination as independent variables, perform linear, logarithmic and exponential fitting on the other variables respectively, obtain the fitting optimal curve and total parameter table, and draw the final three-dimensional surface diagram to further optimize the fitting results, The differential equation is established to consider the influence of the change of product concentration and reactant concentration on the dependent variable. Then, this paper analyzes the changes of substances at different time points in an experiment, in which the independent variable is time, and carries out linear, logarithmic and exponential fitting with ethanol conversion and product selectivity respectively. The fitting parameters are determined when the degree of fitting is the highest. Thus, the relationship between reactants and products with time in the reaction process can be analyzed.
