Galerkin Finite Element Method for Caputo–Hadamard Time-Space Fractional Diffusion Equation

open access: yesMathematics
In this paper, we study the Caputo–Hadamard time-space fractional diffusion equation, where the Caputo derivative is defined in the temporal direction and the Hadamard derivative is defined in the spatial direction separately.

Discrete Fourier and Hadamard transforms

open access: yesElectronics Letters, 1970
Elementary properties of discrete Fourier transforms (d.f.t.) have appeared in recent literature. Corresponding properties of BIFORE (Hadamard) transforms are summarised and compared with those of the d.f.t.

EXPLOITING PARTIALLY RECONFIGURABLE FPGA FOR PERFORMANCE ADJUSTMENT IN THE RVC FRAMEWORK [PDF]

open access: yes, 2012
International audienceIn this paper, we present a method to implement a specific algorithm using the RVC framework and the dynamic partial reconfiguration (DPR). The DPR is a technique allowing to replace modules in a design at run-time.

Geometrically focused training and evaluation of organs‐at‐risk segmentation via deep learning

open access: yesMedical Physics, EarlyView.
Abstract Background Deep learning methods are promising in automating segmentation of organs at risk (OARs) in radiotherapy. However, the lack of a geometric indicator for dosimetry accuracy remains to be a problem. This issue is particularly pronounced in specific radiotherapy treatments where only the proximity of structures to the radiotherapy ...

Achieving robust labeling above the circle of Willis with vessel‐encoded arterial spin labeling

open access: yesMagnetic Resonance in Medicine, EarlyView.
Abstract Purpose To improve the robustness of noninvasive vessel‐selective perfusion imaging and angiography using vessel‐encoded arterial spin labeling (VEASL) when applied to complex vascular geometries, such as above the circle of Willis (CoW) in the brain.

Complex Hadamard Matrix-Aided Generalized Space Shift Keying Modulation

open access: yesIEEE Access, 2017
In this paper, we present a complex Hadamard matrix-aided generalized space shift keying (HSSK) modulation scheme, which introduces complex-Hadamard-based signal vectors at the transmitter to provide higher spectrum efficiency than generalized space ...

Hadamard single-pixel imaging versus Fourier single-pixel imaging

open access: yes, 2017
Single-pixel imaging is an innovative imaging scheme and has received increasing attentions in recent years. It is applicable to imaging at non-visible wavelengths and imaging under low light conditions. However, single-pixel imaging has once encountered

On a New Class of Meromorphic Univalent Function Associated with Dziok_Srivastava Operator

open access: yesJournal of Kufa for Mathematics and Computer, 2015
In this paper, we introduce and study a new class of meromorphic Univalent functions defined by Dziok_Srivastava operator for this class. We obtain coefficient inequality, convex set, closure and Hadamard product (or convolution).Further we obtain a(n,δ

Kriging‐variance‐based multi‐member ensembles of radar–rain‐gauge precipitation estimates: Application in Switzerland

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We explore the variance of the radar–rain‐gauge combination kriging‐based system “CombiPrecip”, showing that it represents satisfactorily the radar–rain‐gauge precipitation uncertainty around the kriging expected value. We then present a method to generate ensembles out of it, which we find to be very similar in texture with the expected‐value image ...
