Unlimited Sampling Theorem Based on Fractional Fourier Transform
Fractal and Fractional, 2023 The recovery of bandlimited signals with high dynamic range is a hot issue in sampling research. The unlimited sampling theory expands the recordable range of traditional analog-to-digital converters (ADCs) arbitrarily, and the signal is folded back into

Non-Fourier heat transport in nanosystems
La Rivista del Nuovo Cimento, 2023 AbstractEnergy transfer in small nano-sized systems can be very different from that in their macroscopic counterparts due to reduced dimensionality, interaction with surfaces, disorder, and large fluctuations. Those ingredients may induce non-diffusive heat transfer that requires to be taken into account on small scales.

Non-ideal sampling in shift-invariant spaces associated with quadratic-phase Fourier transforms
Alexandria Engineering Journal, 2023 Non-ideal sampling has nourished as one of the most attractive alternatives to classical sampling, which relies on shift-invariant spaces. The present study focuses on investigating the non-ideal sampling in shift-invariant spaces associated with the ...

Causality in non-fourier heat conduction
Journal of Physics Communications, 2022 Abstract We present a study of the causal response of non-Fourier heat conduction by introducing a dispersive generalized thermal susceptibility and show it obeys Kramers-Kronig relations. In particular, we discuss the Cattaneo-Vernotte and the dual-phase lag models.

New approach for the determination of the characteristics of signals containing fluctuating harmonics [PDF]
International Journal of Metrology and Quality Engineering, 2011 This paper describes a new approach for the analysis of signals containing fluctuating harmonics. It is based on the Fourier transform, using windowing to reduce the error arising from analysing the signal over a non integer number of signal periods and ...

Hybrid Fourier series and smoothing spline path non-parametrics estimation model
Frontiers in Applied Mathematics and Statistics, 2023 Pathway analysis is one way to determine whether there is a causal relationship between extrinsic and intrinsic factors. The linearity assumption is something that can change the model. The shape of the model is subject to linearity assumptions.
