Authors: Xu Jiangtao , Yang Zhenwei 
Published: June 2020

Abstract
To better solve the problem of data noise caused by the application of optical fibre sensing technology in geological engineering, the overall design of geological engineering monitoring system in three dimensional (3D) visualization environment is firstly carried out in this study, and the data processing module of distributed optical fibre sensing system is designed in detail. Then feature compression algorithm is proposed for the smooth de-noising of geological monitoring data feature. Finally, through the comparison of the data smoothing de-noising of geological engineering with the compression algorithm proposed in this study, the desiccating effect is verified by using three indexes of signal-to-noise ratio, mean square error, and smoothness. The results show that the feature compression algorithm has a good effect on the smooth de-noising of geological monitoring data. At the same time, more unnecessary information is omitted in the adoption of geological engineering, and the smoothness of curves is taken into account, which greatly promotes the widespread application of distributed fibre optic sensing technology in geological engineering.

Published: June 2020

Abstract
Indium zinc oxide (IZO) thin films were prepared by radio frequency magnetron sputtering at room temperature for the applications of Cu(In,Ga)Se2 (CIGS) solar cells. The effect of the RF power during the deposition process on the structural, optical, and electrical properties of the films was investigated. XRD analysis revealed that all films showed an amorphous phase. The average optical transmittance in the range of 300-1500 nm decreased with increasing deposition power. Hall effect measurements show that the optimal hall mobility of 34.22 cm2/Vs and resistivity of 4.09×10−4 Ω•cm were obtained at the power of 90 W. The optimized IZO film was applied to CIGS solar cells, and an efficiency of 13.81% in CIGS solar cell has been achieved.

The protocol applies to system performance requirements and security requirements. The results show that the protocol can effectively solve security problems such as eavesdropping, replay attacks, and loss of synchronization. This system helps protocol designers analyze and compare the security protocols of RFID systems, and at the same time fills the gaps in experimental systems in this field.
Development mode and distribution characteristics of biolimestone of the Shahejie1 Formation in the Changdi Area of the Zhanhua Sag
Authors: Xie Chuanjin 
Published: June 2020

Abstract
Using core, drilling, logging and seismic data, the development and sedimentary evolution of biolimestone of the first member of Shahejie Formation of Zhanhua Sag were researched. The first member of Shahejie Formation Changdi Area is defined as a third-order sequence, and the biolimestone developed in the first member of Shahejie Formation was divided into three fourth-order sequences. The lacustrine transgressive system tract and the lacustrine regressive system tract, where the biolimestone both developed were also identified. The development of biolimestone is influenced by paleoclimate, relative paleowater depth and paleogeomorphology. There are three types of paleo water depth variation in the Member of Shahejie Formation, namely the water withdrawal, the high position water and the low position water. Through paleogeomorphology restoration, it is clear that the biolimestone in the first member of Shahejie Formation is mainly distributed in the southeast and eastern slope trough, and then it is determined that there are two development modes in the study area, which are the biolimestone developed in gentle slope and the biolimestone developed in trough. Due to the periodic change of the lake level, the distribution of the biolimestone in the first member of Shahejie Formation also changed correspondingly. The biolimestone is thicker around the uplift and thinner along the gentle slope direction, and its belt-like distribution is parallel to the periphery of the buried hill.

Authors: Wu Qiong , Fu Qin , Nie Mingxin 
Published: June 2020

AbstractTimely accurate traffic prediction is important in the Intelligent Traffic System (ITS). It has time-varying traffic patterns and the complicated spatial dependencies on traffic network topology which makes the prediction challenging. In this paper, we propose a novel deep learning framework—Graph Wavelet Long Short-Term Memory Neural Network (GWNN-LSTM) to capture the spatial and temporal dependence simultaneously. Moreover, Graph Wavelet Neural Network (GWNN) is utilized for spatial correlations and Long Short-Term Memory Neural Network (LSTM) is used to capture the dynamic temporal correlations in traffic time series data. Experiments on real-world datasets from loop detectors in the highway of Los Angeles County (METR-LA) demonstrate that the proposed GWNN-LSTM model outperforms the state-of-the-art baselines.

Published: June 2020

Abstract
In order to verify the feasibility of the energy recovery of the linear active heave compensation device under the descent compensation condition, the author established a schematic diagram of the hydraulic system based on the heave compensation principle, performed a simulation analysis of the hydraulic system model in a cycle, analysed energy loss of the system under specific sea conditions. Therefore, it is concluded that the gravity potential energy of the load under the descent compensation condition has great potential for recovery. Based on the results of the demonstration, the article proposes an electro-hydraulic energy recovery system of the linear active heave compensation device based on a hydraulic motor-generator. The system model is simulated and analysed in a single cycle under standard operating conditions. The results show that: When the system parameters match reasonably, the heave compensation device has a higher compensation accuracy. The energy recovery rate of the system under the down compensation condition reaches 21.6%, and the effect of energy saving is great. At the same time, simulation analysis shows that under the premise of ensuring the compensation accuracy, changes in the quantitative motor displacement and the viscous friction coefficient of the generator will affect the energy recovery efficiency to varying degrees.
