More than 3 million range measurements from the Chang'E-1 Laser Altimeter have been used to produce a global topographic model of Moon with improved accuracy. Our model, 360th degree and order spherical harmonic expansion lunar radii, is designated as Lunar Topography Model s01 (CLTM-s01). This field, referenced mean radius 1738 km, has an absolute vertical accuracy approximately 31 m spatial resolution 0.25° (∼7.5 km). new greatly previous models in coverage, resolution, also shows polar...
Test-time adaptation (TTA) has increasingly been an important topic to efficiently tackle the cross-domain distribution shift at test time for medical images from different institutions. Previous TTA methods have a common limitation of using fixed learning rate all samples. Such practice would be sub-optimal TTA, because data may arrive sequentially therefore scale change frequently. To address this problem, we propose novel dynamic adjustment method test-time adaptation, called DLTTA, which...
Purpose The symmetry error generated in the machining process of herringbone gears will destroy stability transmission system. purpose this paper is to establish a measurement model gear based on spiral method, and evaluate accuracy measured error. Design/methodology/approach A method proposed. verified by three coordinate measuring instrument. analysis established. influence speed load it analyzed. Findings At same speed, when increases from 100 N·m 500 N·m, system decreases. Under load,...
The possibility to observe satellites with the geodetic Very Long Baseline Interferometry (VLBI) technique is vividly discussed in community, particularly regard future co-location satellite missions. Chinese APOD-A nano can be considered as a first prototype-suitable for practical observation tests-combining techniques Satellite Laser Ranging (SLR), Global Navigation Systems (GNSS) and VLBI on single platform Low Earth Orbit (LEO). Unfortunately, it has hardly been observed by VLBI, so...
Robot-assisted surgery has become progressively more and popular due to its clinical advantages. In the meanwhile, artificial intelligence augmented reality in robotic are developing rapidly receive lots of attention. However, current methods have not discussed coherent integration AI AR surgery. this paper, we develop a novel system by seamlessly merging module visualization automatically generate surgical guidance for education. Specifically, first leverage reinforcement leaning learn from...
Abstract An efficient and versatile synthesis of alcohols via transfer hydrogenation from ketones with isopropanol, utilizing [Ni(6,6′‐(OH) 2 ‐2,2′‐bpy)][Br ] under alkaline conditions, has been documented. It was noteworthy that many readily reducible or labile functional groups such as nitro, cyano, halide, within the same molecular framework, did not undergo any change standard reaction conditions. Furthermore, gram scale successfully carried out good yield using a common route only...
Currently, low Earth orbit (LEO) satellites are attracting great attention in the navigation enhancement field because of their stronger signal and faster elevation variation than medium (MEO) satellites. To meet need for real-time precise positioning, timing (PNT) services, first most difficult task is correcting errors process LEO clock offset determination as much possible. Launched 29 September 2018, CentiSpace-1 (CS01) satellite experimental LEO-based system constellations developed by...
