Class-incremental learning (CIL) under an exemplar-free constraint has presented a significant challenge. Existing methods adhering to this are prone catastrophic forgetting, far more so than replay-based techniques that retain access past samples. In paper, solve the CIL problem, we propose Dual-Stream Analytic Learning (DS-AL) approach. The DS-AL contains main stream offering analytical (i.e., closed-form) linear solution, and compensation improving inherent under-fitting limitation due...
We realized an ultimately advanced imaging system that comprises a hemi-spherically curved, back-illuminated CMOS image sensor (BIS) and integrated lens which doubles the sensitivity at edge of circle increases center by factor 1.4 with one-fifth lower dark current (J <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">d</sub> ) than planar BIS. Because field curvature aberration (A xmlns:xlink="http://www.w3.org/1999/xlink">fc</sub> was overcome in...
In modern life, emotions affect people in all aspects of their work and life. Long-term emotional problems tend to cause physical mental such as depression. The photoplethysmogram(PPG) electroencephalogram (EEG) etc are often used for emotion recognition, because the state produces reactions from different biological systems human body. This article uses an internationally released classification database called DEAP dataset that contains 32-channel standard EEG signals 8-channel peripheral...
A novel SPR biosensor that can achieve a high sensitivity is proposed; therefore, new prism coupling structure based on metal nanowires array layer designed in this paper. The thickness of each medium for the analyzed to obtain optimal spectrum, by finite element method, so able be enhanced greatly. thicknesses are given, and reach as 210.75°/RIU refractive index sensing medium, from 1.30 1.38.
Aiming at the problem that traditional speech acquisition and recognition are susceptible to environmental noise, this paper proposes a flexible graphene sensor detect vocal vibration signals. First, detection with cylindrical microsurface structure substrate is prepared by chemical vapor deposition (CVD) imprint technology, which greatly improves conformal coating cover ability sensitivity of sensor. In range 200–2500 Hz, average voltage gain ∼48 dB, frequency basically covers human...
A surface plasmon resonance biosensor based on a graphene-decorated grating excitation structure is proposed in this paper. The consists of three-layer structure, including graphene layer, and high refractive index layer. material the layer silica. physically deposited ridges. An incident light with transverse magnetic polarization used to excite plasmons mid-infrared spectral region, which highly localized at both ends property sensor improved by dielectric enhances absorption increases...
A novel nanolaser structure based on a hybrid plasmonic waveguide is proposed and investigated. The coupling between the metal nanowire high-index semiconductor with optical gain leads to strong field enhancement in air gap region low propagation loss, which enables realization of lasing at deep subwavelength scale. By optimizing geometric parameters structure, minimal threshold achieved while maintaining capacity ultra-deep mode confinement. Compared previous coupled pair lower can be...
Quasi-phase-matched second-harmonic generation in a pure crystal waveguide (PCW) is presented. A direct-bonded ridge structure with airgap boundary achieved the PCW 3.2 µm periodically poled MgO:LiNbO3. In single-pass configuration, CW 40 mW of blue light was generated power conversion efficiency 59%.
