High-precision femtosecond laser beam shaping in material processing
Authors: Guo Yiming , Wang Yu , Hu Qinglei 
Published: August 2019

Abstract
Laser beam shaping is the process of modulating the amplitude and phase of a laser beam. With the development of the spatial light modulator, laser beam shaping can modulate the light field to arbitrary pattern dynamically via the computer-generated hologram (CGH). Otherwise, femtosecond laser is widely used in material processing owing to its high peak power, low hot effect and nonlinear effects. However, femtosecond laser is not strictly monochromatic, which will introduce dispersion when femtosecond laser diffracted by a spatial light modulator, and deteriorate the effect of beam shaping. Here we present a method of high-precision femtosecond laser beam shaping. Experimental results confirm that the proposed method can be used to shape femtosecond laser beams into arbitrary patterns in the whole field of view (FOV) with the resolution near the optical diffraction limit.

Published: August 2019

Abstract
For the complicated structure and spatial relationship of urban underground pipelines, it’s necessary to employ 3D visualization technology in pipeline management and maintenance. It’s not efficient to use 3D modelling software such as 3DS MAX in building a large range scene, and it’s difficult and cumbersome to develop the functionalities for 3D visualization of urban underground pipelines from scratch by using the programming APIs such as OpenGL and DirectX3D. In this paper, based on the 3D visualization controls and interfaces by SuperMap, an adaptive method is proposed for building 3D models of urban underground pipeline network. At first, the detailed models of the pipe points and pipe segments are designed by 3DS MAX and imported as map symbols into a SuperMap Symbol library. Then the whole pipeline network is loaded and transformed into a 3D scene by using SuperMap interfaces. Moreover, the 3D models of the ground objects such as buildings are cached in OSGB format, and rendered with underground pipelines to support interactive queries and some professional analysis.

Authors: Xiao Xiong , Dong Peng 
Published: August 2019

Abstract
Due to the complicated structure, large equipment is prone to cost risks during the repair process. To assess the cost risk of such equipment, the method of step-by-step decomposition of the repair equipment can be adopted. The repair task is first decomposed into the bottom-level work unit at the system level or equipment level, and the risk factors are identified by the WBS-RBS method, and the risk is calculated by the FAHP method. The factors are combined with the probability values, and the comprehensive probability values of these risk factors are input into the cost risk assessment model based on Anylogic software. In the equipment repair task of a diesel engine, the model realizes the cost risk assessment of the underlying work unit through single agent, and builds the multi-agent to summarize the evaluation results to obtain the repair task cost risk assessment value.

Authors: Zhang Xiaoli 
Published: August 2019

Abstract
In this paper, an outlier screening method based on centrifugal rate is proposed to screen outliers in data, which is to use the size of centrifugal rate to determine whether the data is significantly larger or smaller than other normal values of centrifugal rate. Taking the mean of data as the center, the distance between any point and the mean as the long half axis of the ellipse, and the distance between the normal dimension as the center, the model is established. The eccentricity based on the mean can be obtained, and so on, the eccentricity of all data based on the mean can be obtained. Finally, the centrifugal rate which deviates from the average centrifugal rate obviously surpasses other data is listed as the abnormal value, and the abnormal value is eliminated.

Authors: Hou Xinghai , Yin Dejun 
Published: August 2019

Abstract
In this paper, a nonlinear system state observer and a vehicle upper controller suitable for a four-wheel independent drive vehicle have been proposed. The observer uses Unscented Kalman Filter to observe the longitudinal speed, lateral velocity and yaw rate of the vehicle, and then calculates the side slip angle of the vehicle. The upper controller adopts the control method of yaw rate and side slip angle combined with Sliding Mode Control to calculate the target yaw moment. Finally, the CARSIM-MATLAB co-simulation is carried out to verify the proposed control strategy. The simulation results indicate that the proposed control strategy enables the vehicle to effectively track the target yaw rate and side slip angle simultaneously, ensuring vehicle stability and safety.

Abstract
In this paper, by modifying the smoothness factor of the third-order CWENO scheme, we present the two-parameter CWENO-NZ3 scheme to improve accuracy at critical points. We selected some classical examples for numerical simulation, such as one-dimensional Sod shock tube, Shock-entropy wave interaction, Riemann problem with strong discontinuity and Rayleigh-Taylor instability problem. Numerically comparing with the classical third-order CWENO schemes, it is found that the improved schemes not only improve accuracy and resolution at the extreme points, but also reduce dissipation.

A design method for absorption of low-frequency noise using acoustic metamaterials
Authors: Xu Xi’an , Wang Xiaoming , Mei Yulin 
Published: August 2019

Abstract
This paper investigates the design method for absorbing and isolating low-frequency noise by utilizing the acoustic metamaterials, which consist of mass and membrane vibrators embedded into acoustic materials. Firstly, the unit cell model of the metamaterials is established to analyze characteristics of band-gaps, which is verified further by frequency domain response analysis. And then, the influence of geometric and material parameters of unit cells on the band-gap properties is investigated. Finally, the wave propagation in the metamaterials with finite periodic structures is simulated for the studies of the low-frequency noise isolation, and the effect of different group patterns of unit cells on the isolation of low-frequency noise is discussed. The results show that the greater the density difference between the mass and the base material is, the greater the number of band-gaps and each bandwidth become. And also, as the thickness of membrane increases, the number of band-gaps increases but the band-gaps are narrow and scattered. The finite periodic structures composed of uniform unit cells can hardly widen the low-frequency bandwidth by adjusting the parameters of the components. However, the non-uniform finite periodic structures composed of different unit cells can widen the band-gaps of the whole structure by adjusting parameters of different components.

Abstract
The deep seafloor is closest to the Earth’s interior and the physical, chemical and biological processes of the seafloor interact complexly. Therefore, the observations of the deep seafloor are critical to the study of global climate change and the change laws of ecosystems in complex environments. For the requirements of long-term observation of the deep seafloor and remote real-time data transmission in the South China Sea, an autonomous seafloor observation prototype system is designed, which combines the sea surface buoy and the seafloor junction box with the Electro-Optical-Mechanical cable. At the same time, according to the requirements of marine environmental parameters, dynamic parameters and biodiversity information collection, this paper proposed a distributed data management model based on the CAN bus to improve the data transmission efficiency and ensure the data quality. In this paper, the design of each component of the autonomous seafloor observation system was described in detail, including its hardware, software and communication system. The observation data from the experiment were given. In the sea experiment, the seafloor observation data were transmitted to the shore-based control center in real time through the satellite communication network and stored in a database. 99.4% of the data were successfully received. The results of the sea experiment show that the system can meet the requirements of long-term observation and remote real-time data transmission, and the reliability of the system is verified.

Authors: Wang Zhiwei , Zhai Mingyue 
Published: August 2019

Abstract
Technology of IoT plays an important role in the application of power information collection and fault warning of distribution network equipment. However, the communication technology used in the previous smart grid IoT demonstration application project generally has short coverage distance, high power consumption of terminals and other defects. In this paper, the requirements of typical state monitoring service in distribution network are analysed. The number of potential monitoring terminals is huge, and the service data have the characteristic of “small data”. Traditional technologies such as wireless private network or Zigbee are not suitable for this communication requirement. LPWAN such as NB-IoT and LoRa is very suitable for transmitting a small amount of information over a long distance, which provides a new support for the communication in distribution network.

Through this method, the initial skeleton of the Chinese character calligraphy image is extracted first. Then, the distortion elimination and sorting processes are performed for the initial skeleton, and the accurate skeleton of the Chinese character image is obtained. Finally, the appropriate ink dots are selected to move and render along the skeleton, thus obtaining the dynamic writing effects. Regarding the aspect of skeleton distortion elimination, the initial skeletons are first classified into three different types; then, the processing algorithms are designed respectively according to their morphological features, thus realizing highly efficient recognition and elimination for the skeleton distortion. This method can realize rapid dynamic restoration for calligraphy fonts, such as regular script.

Abstract
Information retrieval is one of the important service contents of libraries. However, Traditional information retrieval methods cannot guarantee the efficient use of book resources and good reader experience. Therefore, this paper mainly discusses how to introduce virtual reality technology into the construction of digital libraries and provide a new service mode for library visual information retrieval. In order to break the traditional way of building information platform in libraries, we propose to construct a library VR information retrieval system, and introduce the architecture, construction process and scene modelling of the system. This system can improve readers’ information retrieval experience from the perception and interaction level, and greatly promote the integration and effective utilization of library information resources.
