Gait recognition, applied to identify individual walking patterns in a long-distance, is one of the most promising video-based biometric technologies. At present, gait recognition methods take whole human body as unit establish spatio-temporal representations. However, we have observed that different parts possess evidently various visual appearances and movement during walking. In latest literature, employing partial features for description has been verified being beneficial recognition....

In this work, 91 vapor pressure data of cis-1,1,1,4,4,4-hexafluoro-2-butene (HFO-1336mzz(Z)) were measured using a Burnett apparatus in temperature range (278 to 443) K and (30 2830) kPa. The sample was analyzed by gas chromatography with mass spectrometry, the deviations caused impurities corrected based on ideal solution model. combined expanded (k = 2) uncertainty measurement is 6.2 mK, (0.30 0.90) On basis literature experimental new Wagner-type equation used correlate data. normal...

We present FastPoseGait, an open-source toolbox for pose-based gait recognition based on PyTorch. Our supports a set of cutting-edge algorithms and variety related benchmarks. Unlike other projects that focus single algorithm, FastPoseGait integrates several state-of-the-art (SOTA) under unified framework, incorporating both the latest advancements best practices to ease comparison effectiveness efficiency. In addition, promote future research recognition, we provide numerous pre-trained...

Abstract Membrane fouling and chlorination have remained the greatest threats to durable reverse osmosis (RO) membrane applications. Here, we report a facile technique of high pressure assisted deposition (HPSD) physically anchor stable graphene oxide (GO) coatings on RO membranes for simultaneous dual‐functional protection against without sacrifice water flux. Thick were directly prepared by HPSD, subsequent “skin‐removing” method was used obtain GO thin with stronger adhesion. The...

Gas sensor based on point contact tungsten trioxide (WO 3 ) was prepared by in-situ induction-heating thermal oxidation of filaments. X-ray diffractometry (XRD) and field emission scanning electron microscopy (FESEM) were employed to analyze the phase morphology fabricated thin films. The results showed that WO films exhibited a monoclinic composed hierarchical micro nano crystals. NO 2 (1-8 ppm) sensing properties sensors Pure Au-sputtering doped (2.5 at%) investigated. gas Au superior...
