Point-Wise Phase Estimation Method in Fringe Projection Profilometry under Non-Sinusoidal Distortion [PDF]
Sensors, 2022 In fringe projection profilometry, high-order harmonics information of distorted fringe will lead to errors in the phase estimation. In order to solve this problem, a point-wise phase estimation method based on a neural network (PWPE-NN) is proposed in ...

Signal Retrieval from Non-Sinusoidal Intensity Modulations in X-ray and Neutron Interferometry Using Piecewise-Defined Polynomial Function [PDF]
Journal of Imaging, 2021 Grating-based phase-contrast and dark-field imaging systems create intensity modulations that are usually modeled with sinusoidal functions to extract transmission, differential-phase shift, and scatter information.

Non-sinusoidal Waveform in Temperature-Compensated Circadian Oscillations. [PDF]
Biophys J, 2019 Time series of biological rhythms are of various shapes. Here, we investigated the waveforms of circadian rhythms in gene-protein dynamics using a newly developed, to our knowledge, index to quantify the degree of distortion from a sinusoidal waveform.

Non-Parametric Kinematic Optimization of Flapping Foil Propulsion Using a Discrete Adjoint Method [PDF]
BiomimeticsOptimizing flapping-foil kinematics for underwater propulsion is challenging due to strong temporal coupling and nonlinear fluid–structure interactions. Most existing approaches rely on parameterized motion profiles, which restrict the accessible design ...

Traceability of Voltage Measurements for Non-Sinusoidal Waveforms [PDF]
Measurement Science Review, 2010 This paper describes the result of work performed at the Laboratoire National de Metrologie et d’Essais (LNE) aiming at developing a standard system to measure RMS value and harmonic contents of distorted voltage waveforms by means of a sampling voltmeter. Thermal converters are used to trace the RMS value to the SI units. The error of the DVM has been

Numerical Analysis of the Effect of the Non-Sinusoidal Trajectories on the Propulsive Performance of a Bionic Hydrofoil [PDF]
Journal of Applied Fluid Mechanics, 2022 Aquatic animals usually generate the effective propulsive force via non-sinusoidally flapping their fins. Inspired by the kinematics of fish, the propulsive characteristics of a NACA012 hydrofoil is numerically studied in this paper.
