A new demodulation procedure for a class of multiplexed signals [PDF]

IECON 2019 - 45th Annual Conference of the IEEE Industrial Electronics Society, 2019
This paper introduces a set of estimators for a wide class of multiplexed signal. The signals of interest are decomposed on independent periodic signals with a shared frequency. This latter set of signals is as general as possible; that is, not necessarily orthogonal or sinusoidal.

Agar‐Based Optical Sensing System With a Phosphorescent Grid Pattern for Measuring Stress Distributions of Root Growth Using the Sampling Moiré Method

Advanced Materials Technologies, EarlyView.
This paper presents an agar medium with a phosphorescent grid pattern that measures the stress distribution generated by growing plant roots. Using phosphorescence, the system optically separates the grid pattern from the root and extracts the grid deformation.

Multidirectional Motion Strategy of Miniature Water Surface Robot Actuated by Single Exciter

Advanced Robotics Research, EarlyView.
A novel multidirectional motion strategy on the water surface based on a single exciter is proposed, and a single‐exciter single‐plate module is developed for actuation. The driving forces generation mechanism of the module is revealed from the perspective of the asymmetric surface wave field.

Intelligent Maintenance Review for Robots: Multimodal Information, Deep Diagnosis and Embodied Artificial Intelligence

Advanced Robotics Research, EarlyView.
This review maps the methods to monitor robots’ health by fusing vibration, sound, control signals, vision, force, and oil information with artificial intelligence. It identifies deep learning, transfer learning, digital twins, and physics‐informed models as key methodological pathways enabling earlier diagnosis, safer human–robot collaboration, and ...

2FSK Communication System Demodulation Algorithm for Novel Acoustically Excited SLF Antennas

水下无人系统学报
There exist some problems for acoustically excited super low frequency(SLF) antennas, such as low transmission power and low received signal-to-noise ratio. In addition, it is difficult to design a narrow-band filter in traditional binary frequency-shift

Disorder‐Induced Extremely Low Thermal Conductivity of Graphite Fluoride

Advanced Science, EarlyView.
This article investigates the effect of fluorination on the thermal conductivity of graphite fluoride, demonstrating the relationship between structural modification and thermal conductivity in an extreme case. The record‐low through‐plane thermal conductivity measured in exfoliated graphite fluoride flakes was found to correlate with the wide ...

Complex demodulation and double demodulation [PDF]

, 1979
A method to complex demodulate signals with amplitude and phase slowly varying with time is proposed. In a first step, classic demodulation is applied that provides a good approximation of the phase sequence and a fair approximation of the amplitude ...

mGluR5 in ECCCK to BLA Circuit Modulates Depressive‐Like Phenotypes through CCK Signaling

Advanced Science, EarlyView.
Dysregulation of mGluR5 and CCK signaling contributes to major depressive disorder, yet circuit‐level mechanisms remain unclear. Here, the ECCCK→BLA pathway is identified as a critical regulator of affective behavior. mGluR5 modulates synaptic function and CCK signaling within this circuit, controlling stress susceptibility and depressive‐like states ...
