In order to study the denitrification effect of NaClO2/Mg(OH)2 seawater solution, the wet oxidation denitrification experiment was carried out by circulating spray. The experiment compared the denitrification time of NaClO2 water solution, NaClO2 seawater solution and NaClO2/Mg(OH)2 seawater solution; at the same time, studied the influence of different NaClO2 concentration, spray solution temperature and NO concentration in flue gas on the denitrification effect of NaClO2/Mg(OH)2 seawater solution. The experimental results showed that during the cyclic spraying process, the NO removal rate of NaClO2 water solution, NaClO2 seawater solution, and NaClO2/Mg(OH)2 seawater solution could reach 100%, and the time to completely remove NO was 68, 85 and 91 minutes, respectively. The NaClO2/Mg(OH)2 seawater solution could keep the pH value above 8 under the action of Hydroxide ion and the acid-base buffering capacity of seawater. Under alkaline conditions, it effectively inhibited the decomposition of NaClO2 in the solution to produce ClO2 gas, and inhibiting the escape of ClO2 was the main reason for increasing the time for NaClO2 to remove NO. The removal rate of NO increased with the increase of the concentration of NaClO2 and the temperature of the spray solution, and decreased with the increase of the NO concentration in the flue gas; however, the denitrification time decreased with the increase of the temperature of the spray solution.

in order to study the influence of error on the performance of planetary roller screw, the tooth profile angle error which has great influence on axial clearance is selected as the research object, and the spiral surface equation of each part is established according to the principle of spatial meshing. based on Hertz contact theory, elastic-plastic deformation theory and deformation coordination principle, the load distribution model of planetary roller screw considering tooth angle error is obtained. The load distribution before and after considering the tooth profile angle error is analyzed by ABAQUS. The results show that the tooth profile angle error will affect the axial clearance of the planetary roller screw pair and increase the non-uniformity of the load distribution of the whole system, but the trend of load distribution at both ends of the roller is not affected. This study provides a basis for the application of planetary roller screw in engineering practice.

The integration and application of existing spatial situation information lacks systematicness and compatibility. Therefore, this paper mainly focuses on how to build a comprehensive framework for space situational knowledge acquisition to solve the above problems. Firstly, the data or information collected from various heterogeneous multi-source information sources are sorted out. Then, the iterative clustering method is used to aggregate the multi-source data to obtain the information addition, and the overall knowledge achievement of spatial situation is generated through comprehensive integration. This is the previous knowledge acquisition method that only obtains spatial target data at different levels and principles for a single sensor, laying a foundation for the subsequent application of spatial situation knowledge.

Object detection based on deep learning needs to collect and centralize a large amount of training data from multiple parties, which leads to data privacy problems. Federated learning has become an effective way to conduct deep learning when training data are distributed. However, traditional federated learning still faces the challenge of security and data heterogeneity. Specifically, the central server will introduce a single point of failure. Malicious clients and statistical heterogeneity of data will affect the performance of the model. To solve the above problems, this paper proposes FedDetectionBC, a federated learning framework for object detection model training, which takes advantage of blockchain to ensure the robustness and auditability of federated learning. To deal with data heterogeneity, a new algorithm (Exchange-FedAvg) is also proposed. Experimental results that FedDetectionBC is more robust than traditional federated learning when there exist malicious clients in the system. The proposed Exchanged-FedAvg can achieve higher accuracy with fewer communication rounds in non-IID settings.

In view of the diversity of visible watermarks and the high cost of human intervention in the process of removing visible watermarks, a method of removing visible watermarks including detection and removal was proposed. Watermarking detection based on YOLO V3 model adopts model fusion method and improves the loss function to improve the generalization of watermarking detection. Based on Generative Adversarial Nets (GAN), the structure similarity is introduced into the loss function by combining perceptual attention mechanism. The network generates images prior to repair images by learning regions other than the watermark. Experimental results show that the proposed method can improve the objective evaluation indexes such as peak signal to noise ratio (PSNR) and structural similarity.

In agricultural production, the harvest of fruit and vegetable is the most time-consuming and laborious link, which is basically completed manually. By the shortage of the fruit and vegetable picking manipulators both at home and abroad. According to the basic process and work requirements of cucumber collection, a cucumber picking manipulator with four degrees of freedom is proposed. the hardware part of the mechanical arm is composed of a base, large and small arms and end-effectors, which can realize the movement of rotation, grasping and placement. As a stable part of the picking machine, the base is rigidly connected with the structural support frame, which mainly plays the role of providing power for the mechanical picking arm and supporting the mechanical rotation. Each joint is controlled by a motor and steering gear, which has the advantages of flexible action, stable operation and good effect. It will not only play an important role in agricultural development, but also be the inevitable trend of agricultural development in the future.

End-to-end speech synthesis technology has already replaced the positions of Statistical Parametric Speech Synthesis (SPSS) in text-to-speech (TTS) field. The end-to-end model based on neural network, does not require a lot of domain knowledge but synthesize more natural speeches. Tacotron is the first model that can synthesize speeches which even human is hard to distinguish. We propose a new end-to-end speech synthesis system which is called Convolution-Recurrent-Convolution Text-to-Speech (CRCTTS). We chose Tacotron as our baseline model and adjust the architecture through fully Convolution Neural Network (CNN) module and Dynamic Convolution Attention (DCA). Besides, we also introduce the attention guided mechanism to our model for accelerating the attention alignment in the decoder module. The model we proposed has been proved that can synthesis speech with better quality and cost less time in terms of training stage and synthesis stage than the baseline model with these technologies.

With the introduction of German Industry 4.0 and Made in China 2025, industrial intelligence and industrial informatization have gradually become the frontier trend of the development of the manufacturing industry. FANUC machine tools as the mainstream machining equipment in the manufacturing industry, their intelligence and information are essential to the transformation of enterprises and the development of manufacturing industries. At present, as the shape of mechanical parts becomes more and more complex, the storage space of machine tool can no longer satisfy the storage of NC program codes generated by complex parts. In addition to this, most companies also lack advanced digital information exchange technology and cannot grasp the specific status of workshop equipment in real time. In order to solve above problems, we use C# programming language to design online machining and monitoring management system, which is based on the RS-232 serial port and Ethernet network port of FANUC machine tools. Finally, we conduct field tests and the designed system runs steady and adequate the actual requirement.
