Published: March 2020

Abstract
To explore and quantify the effect of in-channel aquatic vegetation (IAV) on hyporheic exchange (HE), the research with solute tracer method were launched in a homogenous sand bed flume. The experiments took 3 trials including one control trial and two subsequent trials with only dependent variable of emergent IAV’s canopy area. The hypothesis that that IAV area has the positive correlation with mean hydraulic residence time (HRT) and correspondingly negative correlation with mean rate of HE. Comparation of the experimental support the hypothesis. However, rate of HE shows negative correlation with IAV area increasing at initial period. It is speculated that phenomenon is caused by sediment mobility which changed water pressure diffidence and formed long seepage path under IAV area. The speculation requires further research. The exploration of the complex interaction between IAV and HE requires further is still in its infancy. This research provides the promising evidence to further investigation.

Ambiguity Function of Symmetric Triangular Frequency Modulated Continuous Waveform
Authors: Liu Jing , Zhou Xingang , Zhu Yanping 
Published: March 2020

Abstract
The ambiguity function of Linear Frequency Modulated (LFM) pulse compression signal has been discussed widely, but the ambiguity function of LFM continuous waveform (CW) is rarely heard about. In this paper, the Single Periodic Ambiguity Function (SPAF) of Symmetric Triangular Frequency Modulated Continuous Waveform (STFMCW) is analytically derived in an explicit form, and its Periodic Ambiguity Function (PAF) is obtained by the relationship between SPAF and PAF. According to both theoretical analysis and simulated results, it is obtained that the dominant feature of the SPAF about STFMCW is the intact X-shaped diagonal ridge and two halves with 3 peaks, and a low pedestal which has a shape of the figure “8”. Using the frequency-difference of up-sweep and down-sweep respectively, the range-velocity coupling can be eliminated for a moving target. And any cuts of SPAF or PAF of STFMCW can be gotten.
Study on transdermal drug delivery with microneedle array
Authors: Li Yan , Zhang Dawei , Zhang Peiyu 
Published: March 2020

Abstract
New pathways of drug administration have being explored because there exist weaknesses in the traditional drug delivery such as either potential degradation in the gut in oral method or pain and infection resulted from transdermal injection. Transdermal drug delivery (TDD) is a promising technology for drug administration. Among TDD, Microneedles (MNs) made transdermal drug delivery easier and more effective. The development of microneedles is necessary to eliminate or reduce the problems employing conventional needles such as pain, needle-stick injuries or needle re-use. In order to explore the drug delivery in human tissues, we made the hypothetical models of the flow of drug and to depict the flow and the moving ways of drugs. The delivering properties of drugs into skin tissue are analysed by adopting the previous hypothetical models. The results showed that the exiting velocity from the microneedle array played an important role to impact the efficiency of drug delivery. The large exiting velocity would accelerate the transdermal drug delivery and prompt drug into the circulation. In addition, the diffusion can be ignored due to a little influence.

Published: March 2020

Abstract
With the increase in the number and length of pipelines in China, pipeline damage accidents are increasing as well. Traditional methods do not allow real-time monitoring of pipelines. The development of the Internet of Things has promoted the monitoring techniques and the development of pipelines. But a problem arises as to how to deal with the huge data generated by monitoring systems. This paper proposes a real-time data visualization method for oil pipeline monitoring based on the Internet of Things. In this method, the measurement nodes of the sensing layer collect the pipeline data and transmit them to the server of the application layer through the network layer. A web application is built based on Spring MVC in the application layer of the Internet of Things to process the data through the interaction between the front and the back. The data visualization algorithm based on Echarts and AJAX is used to position the pipelines and the real-time situation of pipeline anomalies. The results show that with this method, the program runs faster and has higher monitoring efficiency, and the poor readability problem of the oil pipeline data is solved.

A Collaborative Filtering Methods Based on Expected Utility
Authors: Zhang Tao , Zhao Kun , Zhang Xianhua , Zou Yan 
Published: March 2020

Abstract
In recent years, there has been a variety of improved collaborative filtering methods, which promote accuracy of recommendation by analysing too much user or item information like individual characteristics, application scenarios and so on. This increases the time complexity of the algorithm and leads to low efficiency of recommendation. Therefore, how to improve the quality of recommendation through analysing a small amount of effective information has attracted more attention in the research of collaborative filtering methods. This paper proposes a collaborative filtering method based on expected utility from the perspective of the economic significance of user rating. Firstly, the method establishes the corresponding similarity criterion and calculates the similarity between users or items by scoring expectation. Then, the nearest neighbour set is calculated and the final prediction is got. Finally, our method is validated by the experimental results using movielens-1m data set. The results show that the collaborative filtering method proposed in this paper is simpler and more feasible compared with the traditional IBCF, KNN and other mainstream methods, and can improve the efficiency and quality effectively of recommendation only using less information. This work has significance both in theoretical research and practical application value.
