Numerical Simulation of the Lunar Polar Environment: Implications for Rover Exploration Challenge

open access: yesAerospace, 2023
The lunar polar regions are key areas for future exploration due to the long-term continuous illumination and persistently shadowed regions that can cold trap abundant water and other volatiles.

Experimental study on electrostatic migration of different mineral particles composing lunar dust under electron irradiation

open access: yesFrontiers in Astronomy and Space Sciences, 2023
Dust electrostatic migration is one of the primary causes of dust events on the surface of airless celestial bodies, which can result in multiple dust phenomena, including lunar horizon glow and dust pools, and also offer crucial insights into the ...

Deep Space [PDF]

open access: yesInternational Journal of Architectural Computing, 2006
The work described here explores the problem of how digital technologies can enrich the experience of spatiality and social interaction in space(s). An existing café space at the School of Design of the Hong Kong Polytechnic University is linked to a “twin” in the form of an online-accessible environment.

Learn Generalization Feature via Convolutional Neural Network: A Fault Diagnosis Scheme Toward Unseen Operating Conditions

open access: yesIEEE Access, 2020
In recent years, Convolutional neural networks (CNNs) have achieved start-of-art performance in the fault diagnosis field. If there is no available information on the unseen operating conditions, the model trained on the seen operating condition cannot ...

Mission analysis of lunar scientific research station based on MBSE

open access: yesHangkong gongcheng jinzhan, 2023
After the completion of the three steps of "circling back", the lunar exploration has changed from the short-term single point exploration to the long-term exploration of lunar scientific research stations with the con-struction of lunar surface ...

Spectral interpretation of late-stage mare basalt mineralogy unveiled by Chang’E-5 samples

open access: yesNature Communications, 2022
Laboratory spectroscopic and X-ray diffraction analyses on the Chang’E-5 lunar soil samples have demonstrated that the spectral features of lunar late-stage mare basalts are representative of iron-rich high-Ca pyroxene rather than olivine.

An Improved Similarity Trajectory Method Based on Monitoring Data under Multiple Operating Conditions

open access: yesApplied Sciences, 2021
With the complexity of the task requirement, multiple operating conditions have gradually become the common scenario for equipment. However, the degradation trend of monitoring data cannot be accurately extracted in life prediction under multiple ...

Deep Space

open access: yes, 2021
CERN's Large Hydron Collider (LHC) in Geneva is currently the record holder in acquiring huge amounts of experimental science data. The reason is simple: the target particles are extremely rare and are searched for in an ocean of other events. In 2019 CERN's advanced tape storage system Castor held 330 petabytes, in a very sustainable way compared to ...

Unraveling the Role of Electron Plateau Distributions in the Power Gap Formation of Chorus Waves: Van Allen Probes Observations

open access: yesGeophysical Research Letters, 2023
The power gap of chorus waves at ∼0.5fce has been discovered for decades, but its generation mechanism is still under debate. Previous studies have revealed that electron plateau distributions are vitally important for the gap formation.

A New Time Series Similarity Measurement Method Based on the Morphological Pattern and Symbolic Aggregate Approximation

open access: yesIEEE Access, 2019
Aiming at the problem that the traditional similarity measurement methods cannot effectively measure the similarity of the time series with the difference both in the trend and detail, this paper proposes a new time series similarity measurement method ...
