This paper studies the problem of resolving data inconsistency from multiple sources in managing related to power equipment for China’s state grid corporation. proposes automatically align inconsistent devices sources, i.e., same that have entries with different values each source, by HENGE, a HEtetrogeneous Network GEneration model. HENGE builds into heterogeneous graph, and captures complex p...

Turbulence in the atmosphere severely degrades the imaging properties of large astronomical telescopes. At visible wavelengths, the resolving power of even the largest telescope is no greater than that of an instrument of 30-cm aperture. In principle, diffraction limited imaging can be recovered through the techniques of adaptive optics in which the shape of a deformable optical element in the ...

X-shooter is a new high-efficiency spectrograph observing the complete spectral range of 300-2500 nm in a single exposure, with a spectral resolving power R>5000. The instrument will be located at the Cassegrain focus of one of the VLT UTs and consists of three spectrographs: UV, VIS and Near-IR. This paper addresses the design, hardware realization and performance of the Near-IR spectrograph o...
