2D face presentation attacks are one of the most notorious and pervasive spoofing types, which have caused pressing security issues to facial authentication systems. While RGB-based anti-spoofing (FAS) models proven counter attack effectively, existing FAS suffer from overfitting problem (i.e., lack generalization capability data collected an unseen environment). Recently, many been devoted capturing auxiliary information (<i>e.g</i>., depth infrared maps) achieve a more robust liveness...
Source-free domain adaptation (SFDA) aims to transfer knowledge from the well-trained source model and optimize it adapt target data distribution. SFDA methods are suitable for medical image segmentation task due its data-privacy protection achieve promising performances. However, cross-domain distribution shift makes difficult adapted provide accurate decisions on several hard instances negatively affects generalization. To overcome this limitation, a novel method `supportive negatives...
Haptic feedbacks are widely adopted in mobile and wearable devices to convey various types of notifications the users. This paper investigates design evaluation thermal haptic feedback on an earable form factor with multiple thermoelectric (i.e. Peltier) modules. We propose ThermEarhook, a device that can provide hot cold stimuli at points auricular skin area. To investigate users' perception area, we develop series ThermEarhook prototypes 3, 4, 5 Peltier While most existing research...
A Chinese solar greenhouse (CSG) is a horticultural facility that uses energy to promote growth environment for crops and provides high-efficiency thermal storage performance meet the demand of vegetables’ in winter. Besides being an important load-bearing structure CSGs, north wall heat sink, storing during day order act as source night. At times, night temperature lower than minimum requirement vegetables, additional heating needed. Therefore, optimizing release CSG approach improving...
Abstract The membrane oxygenator is an essential component in the Extracorporeal Membrane Oxygenation (ECMO) system to offer temporary support respiratory system. This study aims optimize hemodynamic performance and reduce thrombosis risk of a prototype using computational fluid dynamics. Numerical simulations steady laminar flow full-scale (model 1) two optimized structure Models 2 3 at rates 5∼7L/min are carried out porous media model. Flow-field-based hydraulic indicators thrombus...
<title>Abstract</title> In the present paper, unsteady cavitating turbulent flow over twisted NACA66 hydrofoil has been investigated based on an SST <italic>k</italic>-<italic>ω</italic> partially averaged Navier-Stokes (MSST PANS) model i.e., NMSST PANS model, where production term of kinetic energy in turbulence is modified with helicity. Compared experimental data, cavitation evolution, and its characteristic frequency are satisfactorily predicted by proposed model. It revealed that...
Abstract The hypersonic boundary layer (HBL) transition on a slender cone at moderate incidence has been studied via symmetry-based length model: the SED-SL model. specifies an analytic stress function (which defines eddy viscosity) parameterizing two-dimensional multi-regime structure characterizing laminar-turbulence transition. Previous studies show accurate predictions by for airfoil flows different subsonic Mach numbers, Reynolds numbers and angles of attack, especially drag coefficient...
