Abstract ：
This study aims to explore the correlation between the activity trajectory of Crested Ibis and meteorological changes. The trajectory data of Crested Ibis were obtained using the HQBG3621L backpack-style tracker, and the spatiotemporal characteristics of the trajectory data were analyzed to obtain information on the activity range and habitat of Crested Ibis. The Scheirer-Ray-Hare test and Kruskal-Wallis test were used to investigate the impact of meteorological factors on the activity of Crested Ibis. The study found that meteorological factors have a certain influence on the habitat selection and activity patterns of Crested Ibis. Through this research, a better understanding of the interaction between Crested Ibis and the meteorological environment can be achieved, providing a scientific basis for the conservation and ecological management of Crested Ibis.

Abstract ：
In this paper, we firstly introduce the definition of the fuzzy metric of sets, and discuss the properties of fuzzy metric induced by the Hausdorff metric. Then we prove the limit theorems for set-valued random variables in fuzzy metric space; the convergence is about fuzzy metric induced by the Hausdorff metric. The work is an extension from the classical results for set-valued random variables to fuzzy metric space.

Abstract ：
This research mainly studies the factors influencing the efficiency of energy utilization. Firstly, by calculating Moran'sI and local indicators of spatial association (LISA) of energy efficiency of regions in mainland China, we found that energy efficiency shows obvious spatial autocorrelation and spatial clustering phenomena. Secondly, we established the spatial quantile autoregression (SQAR) model, in which the energy efficiency is the response variable with seven influence factors. The seven factors include industrial structure, resource endowment, level of economic development etc. Based on the provincial panel data (1998-2016) of mainland China (data source: China Statistical Yearbook, Statistical Yearbook of provinces), the findings indicate that level of economic development and industrial structure have a significant role in promoting energy efficient. Resource endowment, government intervention and energy efficiency show a negative correlation. However, the negative effect of government intervention is weakened with the increase of energy efficiency. Lastly, we compare the results of SQAR with that of ordinary spatial autoregression (SAR). The empirical result shows that the SQAR model is superior to SAR model in influencing factors analysis of energy efficiency.

Abstract ：
During human-robot collaborations (HRC), robot systems must accurately perceive the actions and intentions of humans. The present study proposes the classification of standing postures from standing-pressure images, by which a robot system can predict the intended actions of human workers in an HRC environment. To this end, it explores deep learning based on standing-posture recognition and a multi-recognition algorithm fusion method for HRC. To acquire the pressure-distribution data, ten experimental participants stood on a pressure-sensing floor embedded with thin-film pressure sensors. The pressure data of nine standing postures were obtained from each participant. The human standing postures were discriminated by seven classification algorithms. The results of the best three algorithms were fused using the Dempster-Shafer evidence theory to improve the accuracy and robustness. In a cross-validation test, the best method achieved an average accuracy of 99.96%. The convolutional neural network classifier and data-fusion algorithm can feasibly classify the standing postures of human workers.

Abstract ：
The goal of this study was to recognize human standing postures in human-robot collaborations such that the robot can serve the human operator better. An intelligent sensing floor was developed based on a thin-film pressure sensor and a human standing posture dataset was obtained by transforming the pressure data into a pressure image. A human standing posture recognition method based on an improved convolutional neural network is proposed. The results of the experiments demonstrate that a convolutional neural network can be used in the field of pressure images. The proposed method returned a recognition rate of 96.6%. Compared to the traditional neural network, the improved convolutional neural network model has better performance. The study results are expected to be used in standing posture monitoring to provide additional data for a robot in a human-robot collaboration system. © 2020 - IOS Press and the authors.

Abstract ：
城市轨道交通站点的使用便利程度和空间环境质量影响着轨道交通出行比率,而轨道交通作为公共交通方式之一,其出行率的高低反映着城市建设是否具有可持续性.国际成功经验表明,站点地区开发影响着城市空间发展,本文以北京东站地块规划设计为例,对站城一体化的轨道交通枢纽地块建设方式展开探讨.文章认为,轨道交通枢纽地块与城市的一体化水平和站城之间在交通衔接、产业相关、空间互补以及场所文脉这几个方面的协调水平息息相关.衔接良好的交通方式、促使人与自然良性互动的空间环境品质、彰显城市人文精神的建筑景观特征,以及与城市互补的产业发展将有力地促进交通枢纽的发展,满足人们便捷出行与高品质的生活需求,从而实现站城一体化和城市的可持续化.

In last few years, with the rapid development of robot technology, human-machine interaction technology has increasingly become the focus of many researchers. The security of human-computer interaction is becoming more and more important. As an important part of human-machine interaction, robot active sensing has also become an important field of human-machine interaction. Aiming at the requirement of active sensing technology in the field of human computer interaction, a low-cost data acquisition system for surface pressure sensing is designed by using STM32 microcontroller and film pressure sensor matrix. The system architecture, acquisition circuit and high-speed communication circuit are discussed detailly in this paper. The experimental results show that the system can collect all sensors' data of the pressure matrix, data acquisition frequency is 50Hz. The real-time display of the host computer is realized, and the network expansion interface is reserved to facilitate the expansion of the system. The linear fitting method is used to correct the sensors, and the perception accuracy of the pressure matrix sensors is improved. The pressure sensing surface can be used to create the perception of the floor, the cushion or desktop perceived perception and so on. It is a useful supplement to the field of active perception in the field of human computer interaction.
