The blast furnace is a highly energy-intensive, polluting, and extremely complex reactor in the ironmaking process. Soft sensors are key technology for predicting molten iron quality indices reflecting energy consumption operation stability, play an important role saving energy, reducing emissions, improving product quality, producing economic benefits. With advancement of Internet Things, big data, artificial intelligence, data-driven soft processes have attracted increasing attention from...
A wide-angle planar metamaterial structure exhibiting strong absorption is presented. The functions as a near-perfect absorber with the incident electric field propagating not only across but also along gaps of individual split ring resonator (SRR) elements. It coupling adjacent SRRs that provides capacitance necessary to excite LC resonance for absorption. Both simulations and experiments are shown in this paper. experimental results indicate when propagates SRR elements, obtains...
We report the design, simulation, and measurement of a magnetic-type metamaterial absorber with needlepoint-shape pattern in microwave region. Experimental result shows that expands absorption bandwidth magnetic by more than 65%, which is related to LC resonances. Different from non-magnetic absorber, power loss proposed dominated loss. The dielectric are both strengthened resonance. has applications area eliminating energy.
Comprehensive Summary Traumatic brain injury (TBI) constitutes a cluster of disorders resulting from external physical forces that undermine the structure or function brain. TBI brings high disability and mortality rates to patients. Hence, early diagnosis is utmost importance. Current approaches mainly encompass computed tomography magnetic resonance imaging; however, there are still constraints in diagnosing due limited spatial resolution long scan durations. Herein, based on advantages...
Twisted few-layer graphene (tFLG) has emerged as an ideal model system for investigating novel strongly correlated and topological phenomena. However, the experimental construction of tFLG with high structural stability is still challenging. Here, we introduce a highly accessible method fabricating robust by polymer micro-tip manipulated origami. Through using self-prepared micro-tip—which composed multiple dimethylpolysiloxane, poly(vinyl chloride), graphite sheets—to fold layers,...
In this paper, a triple-band planar absorber with high-impedance surface (HIS) is designed and fabricated. The structure composed of polyurethane foam sandwiched between lossy sheet frequency selective surfaces (FSS) perfect electric conductor. FSS possesses different resistances in periodic composite unit as compared typical HIS absorber. Losses the are introduced by printing square ring pattern on blank stickers using various resistive inks. Physical mechanism absorbers analyzed equivalent...
Resonances of the high impedance surface (HIS) absorber with periodic trapezoid-coupling pattern were studied. The theoretical, numerical, and experimental study showed that a frequency dispersion equivalent resistance could break single resonance limitation. limitation is induced by non-dispersive feature in simple patterned HIS absorber. Therefore, multi-resonances originated from effectively expanded absorption bandwidth. proposed had thickness reduced 41% −15 dB bandwidth broadened 50%...
The surface defect has a direct impact on the performance and quality of final product, so it is crucial to identify key factors causing defect.

It can be found that the (222) plane crystallization improves increase O/Ar ratio,...
Although few-shot action recognition based on metric learning paradigm has achieved significant success, it fails to address the following issues: (1) inadequate relation modeling and underutilization of multi-modal information; (2) challenges in handling video matching problems with different lengths speeds, misalignment sub-actions. To these issues, we propose a Two-Stream Joint Matching method contrastive (TSJM), which consists two modules: Multi-modal Contrastive Learning Module (MCL)...
