Dynamic Single Branch Non-Uniform Sampler
, 2013 International audienceWe consider the problem of designing an effective sampling scheme for sparse multi-band signals. Based on previous results on periodic non-uniform sampling (Multi-Coset) and recent advances in Compressive Sensing (CS), we propose a ...

Finiteness theorems on elliptical billiards and a variant of the dynamical Mordell–Lang conjecture
Proceedings of the London Mathematical Society, Volume 127, Issue 5, Page 1268-1337, November 2023., 2023 Abstract We offer some theorems, mainly finiteness results, for certain patterns in elliptical billiards, related to periodic trajectories; these seem to be the first finiteness results in this context. For instance, if two players hit a ball at a given position and with directions forming a fixed angle in (0,π)$(0,\pi )$, there are only finitely many ...

Basin Research, Volume 35, Issue 4, Page 1530-1554, August 2023., 2023 Fluvial architecture in Palaeozoic foreland basins in the Appalachians is used to reconstruct drainage evolution and, thereby, provides insights on progressive terrane accretion in the hinterland. Drainage basins increased in size from the Late Ordovician (Taconic) to Late Devonian (Acadian) then decreased in size in the Pennsylvanian (Alleghanian ...

Orientation relationships, orientational variants and the embedding approach
Journal of Applied Crystallography, Volume 56, Issue 3, Page 725-736, June 2023., 2023 A statistical approach is developed for handling some standard problems involving orientation relationships. The approach is based on directional statistics.For phase transformations within polycrystalline materials, the connection between the crystal orientations of parent grains and those of child grains is usually expressed in terms of (theoretical ...

MULTI-COSET SAMPLING AND RECONSTRUCTION OF SIGNALS: EXPLOITING SPARSITY IN SPECTRUM MONITORING
, 2013 We present an analytical representation of multi-coset sampling (MCS) and implement the proposed scheme on spectrum data to analyze the effect of MCS that requires less samples. Sampling pattern (SP) selection, which is one of the most significant phases

A low-complexity sub-Nyquist sampling system for wideband Radar ESM receivers [PDF]
, 2014 The problem of efficient sampling of wideband Radar signals for Electronic Support Measures (ESM) is investigated in this paper. Wideband radio frequency sampling generally needs a sampling rate at least twice the maximum frequency of the signal, i.e ...

Adaptive non-uniform sampling of sparse signals for Green Cognitive Radio [PDF]
, 2016 International audienceBased on previous results on periodic non-uniform sampling (Multi-Coset) and using the well known Non-Uniform Fourier Transform through Bartlett's method for Power Spectral Density estimation, we propose a new smart sampling scheme ...

Magnetic Resonance in Medicine, Volume 96, Issue 5, Page 2489-2504, November 2026.ABSTRACT Purpose To improve the accuracy of diffusion‐weighted powder average signals for diffusion encoding with arbitrary b‐tensors. Methods We identify an intrinsic dihedral (D2) symmetry of diffusion signals for arbitrary diffusion encoding, which defines their natural signal space (a quotient of 3D rotations). Based on this, we propose a method to
