The integration of Information and Communication Technologies (ICT) into the modern power system makes it a complicated cyber-physical system (CPS). In this case, an adversary may find some loopholes, penetrate to CPS layer, compromise data, and consequently result in security and stability issues. In this paper, we proposed a laboratory set up to emulate the attacker's behavior and then detect the injected false data. To this end, RTU hardware and software are used to simulate a typical SCADA system. A protocol analyzer software is also employed to simulate a cyber-attack, inject false data, and send it to the control center. In the second stage, we developed a two-stage framework to detect FDIA. First, the LSTM, as a supervised learning algorithm, is utilized to build a predictive model. In this process, hyperparameter optimization is implemented to improve the accuracy of the developed model. In the second stage, an unsupervised scoring algorithm is applied to the real-time data to find the sequences of injected false data. Also, a penalty factor is considered during the detection procedure to prevent the algorithm from greedy search behavior. Simulation results on a real-world data set (Chicago load/weather) show the proposed method's effectiveness in the cyberattack implementation and FDIA detection problem.

The dike-pond system (DPS) is the integration of a natural or man-made pond and crop cultivation on dikes, widely distributed in the Pearl River Delta and Jianghan plain in China. It plays a key role in preserving biodiversity, enhancing the nutrient cycle, and increasing crop production. However, DPS is rarely mapped at a large scale with satellite data, due to the limitations in the training dataset and traditional classification methods. This study improved the deep learning algorithm Cascade Region Convolutional Neural Network (Cascade R-CNN) algorithm to detect the DPS in Qianjiang City using high-resolution satellite data. In the proposed mCascade R-CNN, the regular convolution layer in the backbone was modified into the deformable convolutional layer, which was more suitable for learning the features of DPS with variable shapes and orientations. The mCascade R-CNN yielded the most accurate detection of DPS, with an average precision (AP) value that was 2.71% higher than Cascade R-CNN and 11.84% higher than You Look Only Once-v4 (YOLOv4). The area of oilseed rape growing on the dikes accounted for 3.42% of the total oilseed rape planting area. This study demonstrates the potential of the deep leaning methods combined with high-resolution satellite images in detecting integrated agriculture systems.

To reduce the pain and the probability of cross-infection caused by the invasive blood glucose testing instruments, the ex vivo glucose measurement is of high significance. The electrical property of blood varies with the density of the glucose, which can be sensed by measuring its reflected coefficient in millimeter-wave. In this article, we built a contactless glucose solution concentration measurement system based on 77-GHz FMCW radar. Several preliminary signal processing algorithms are cascaded with a deep neural network to improve the accuracy of glucose solution concentration measurement. Our experiment shows that the resolution of this ex vivo glucose measurement can achieve up to 0.1 mg/mL.

A novel sparrow search algorithm and convolutional neural network (SSA-CNN) method is proposed for oil pipeline leakage detection. Firstly, the proposed SSA-CNN method converts the input data from time series to two-dimensional matrix, and the classification conditions of different convolution kernel sizes and different pooling sizes are compared. Then, the SSA algorithm is used to optimize the parameters of the CNN. The simulation results show that, compared with the traditional machine learning method, using two-dimensional data as input can enhance the neural network's extraction of eigenvalues. The proposed SSA-CNN method was able to accurately classify 148 sample points in 150 test sets with an accuracy rate of 98.67%, which is not only higher than traditional machine learning methods, but also further improves the classification capability of CNN, while the SSA-CNN method can use the parameters already learned in the test set to ensure real-time detection.

Network Intrusion Detection Systems (NIDS) have been the most effective defense mechanism against various network attacks. As attack patterns have been intelligently and dynamically evolving, the deep learning-based NIDSs have been widely adopted to improve intrusion detection accuracy. Autoencoders, one of the unsupervised neural networks, are generative deep learning models that learn to represent the data as compressed vectors without class labels. Recently, various autoencoder-generative deep learning models-have been used for NIDS in order to efficiently alleviate the laborious labeling and to effectively detect unknown types of attacks (i.e. zero-day attacks). In spite of the effectiveness of autoencoders in detecting intrusions, it requires tremendous effort to identify the optimal model architecture of the autoencoders that results in the best performance, which is an obstacle for practical applications. To address this challenge, this paper rigorously studies autoencoders with two important factors using real network data. We investigate how the size of a latent layer and the size of the model influence the detection performance. We evaluate our autoencoder model using the IDS benchmark data sets and present the experimental findings.

Modulation recognition as an important part of signal processing has been widely used in the field of satellite communication. Since the present existing modulation recognition method is still requires manual processing by professionals, automatic modulation recognition (AMR) is proposed. It has adaptive modulation capabilities to sense and learn environments and make corresponding adjustments. In this paper, we proposes a deep learning classification algorithm called Convolutional Long-Short Term deep Neural Network (CLDNN) to implement AMR. This model integrates architectures of Convolutional Neural Network (CNN), Long Short-Term Memory (LSTM) and deep neural networks (DNN) model. It was trained on the RadioML2016.10a dataset that composed of eleven commonly used modulation modes with different signal to noise ratio(SNR). The signal was generated in a real system using GNU radio to classify modulation. We adopt dropout instead of pooling operation to achieve higher recognition accuracy. In addition, comparisons with Residual Neural Network(ResNet) and Visual Geometry Group(VGG) models are presented. Experimental results demonstrate the significant performance advantage and application feasibility of the CLDNN model for AMR.

EMI Radiation Prediction and Structure Optimization of Packages by deep learning

With a rapid increase in operating frequency and package complexity, conventional analysis methods cannot efficiently cope with current complex electromagnetic interference (EMI) issues. In this paper, a new method built on a deep neural network (DNN) model is proposed to accurately and rapidly predict the maximum radiated electric field at 3-meters of a wire-bond ball grid array (WB-BGA) package. The key hyper-parameters of the DNN model, such as the learning rate and type of optimizers, are discussed in depth so as to attain optimal performance. Predicted radiation results by the DNN model and the results of the full-wave simulation show good agreement. Once DNN is trained, the prediction time is in the order of milliseconds and the model size is in megabytes, which can acquire the predicted radiation quickly and accurately and save storage space. Furthermore, to prevent the radiation from exceeding requirements, package structures are optimized by adjusting those parameters sensitive to radiation and disregarding insensitive parameters. The sensitivity of these WB-BGA package structural parameters to EMI radiation can be analyzed quickly based on data with different deviations generated by the trained DNN model. The sensitive parameters are adjusted according to their correlation with EMI radiation. The effectiveness and feasibility of the optimization method are verified by the WB-BGA package with two sets of different structural parameters.

It is a challenge work to control the complex robot system with disturbances. To solve this problem, an intelligent fuzzy sliding mode control method is proposed in this paper. Firstly, the dynamics model of the complex robot system is presented under disturbances. Then, based on the combination of sliding mode control and fuzzy logic control, the double fuzzy sliding mode controller is designed. In addition, due to the complexity of the dynamics model, it is very difficult or even impossible to obtain the exact dynamics model in practical application, therefore, a deep learning algorithm is developed, which can approximate the dynamics model as close as possible. And the stability of the proposed control method is analyzed by theory. Finally, the proposed intelligent fuzzy sliding mode control method is successfully applied to a KUKA robot system, which is compared with the existing control methods, and its superiority is demonstrated.
