| 1 | First results from a 760-GW linear transformer driver module for Z-pinch research显示文摘In this paper,the results of tests on a 0.76-TW linear transformer driver(LTD)module for Z-pinch research are presented for the first time.Ten LTD cavities,each generating a 1-MA/90-kV pulse on a matched load,were connected in series with a magnetically insulated voltage adder to drive the e-beam diode.Three inner stalks with different radii were tested,and the results indicate that the output parameters of the ten cavities are sensitive to the cathode radii.As an intermediate step,a high-current pulse with 832 kV/912 kA/130 ns was obtained on the e-beam diode.To date,this is the maximum power generated directly by a fast LTD with mega-ampere current output. | Lin Chen Wenkang Zou Jihao Jiang Liangji Zhou Bing Wei Fan Guo An He Weiping Xie Jianjun Deng Meng Wang Jie Wang Yuanjun Zhang | 2021 | Matter and Radiation at Extremes2021，6，4： | 1 |
| 2 | Who are on the road? A study on vehicle usage characteristics based on one-week vehicle trajectory data显示文摘Understanding the characteristics of passenger vehicle use is the prerequisite for effective urban management.However,it has been challenging in the existing literature due to the lack of continuously observed data on passenger vehicle use.Thanks to the advances in data collection and processing techniques,multi-day vehicle trajectory data generated from volunteered passenger cars provide new opportunities for examining in depth how people travel in regular patterns.In this paper,based on a week’s operation data of 6600 passenger cars in Shanghai,we develop a systematic approach for identifying trips and travel purposes,and classify vehicles into four categories using a Gaussian-Mixed-Model.A new method is proposed to identify vehicle travel regularities and we use the Z Test to explore differences in travel time and route choices between four types of vehicles.Wefind that commercially used vehicles present high travel intensity in temporal and spatial aspects and the use intensity in elevated roads is higher for household-used commuting vehicles than semi-commercially used vehicles.The methodologies and conclusions of this paper may provide not only theoretical support for future urban traffic prediction,but also guidance for employing customized active traffic demand management measures to alleviate traffic congestion. | Jihao Deng Yiqing Cui Xiaohong Chen Chris Bachmann Quan Yuan | 2023 | International Journal of Digital Earth2023，16，1： | 0 |
