A Compressed Sensing Framework for Magnetic Resonance Fingerprinting [PDF]

, 2014
Inspired by the recently proposed magnetic resonance fingerprinting (MRF) technique, we develop a principled compressed sensing framework for quantitative MRI. The three key components are a random pulse excitation sequence following the MRF technique, a

From Adult to Adolescent: Alignment in Clinical Trials and Outcomes in Axial Spondyloarthritis

Arthritis Care &Research, Accepted Article.
Spondyloarthritis (SpA) is a group of chronic inflammatory diseases encompassing axial and peripheral forms, with up to 20% of patients developing symptoms before age 16. Despite this substantial pediatric burden, treatment options for juvenile‐onset SpA (JSpA), particularly those with axial disease (axJSpA), remain limited.

Ultra fast charging station harmonic resonance analysis in the Dutch MV grid: application of power converter harmonic model [PDF]

, 2017
This article introduces an advanced converter harmonic model that can be used to study harmonic resonance when the ultra-fast charging station (UFCS) is connected to the medium-voltage (MV) grid.

Adaptive Observer for Coupled Wave PDE and Infinite ODE With Sampled Data and Unknown Input: Application to Brain Hemodynamics Estimation

International Journal of Adaptive Control and Signal Processing, EarlyView.
This article proposes a convergent adaptive observer for a damped wave PDE and an infinite‐dimensional ODE coupled in cascade using sampled‐in‐space ODE state measurements. The proposed observer estimates the distributed states of the PDE and ODE along with unknown PDE parameters and spatial input.

Second-harmonic double-resonance cones in dispersive hyperbolic metamaterials [PDF]

, 2014
We study the formation of second-harmonic double-resonance cones in hyperbolic metamaterials. An electric dipole on the surface of the structure induces second-harmonic light to propagate into two distinct volume plasmon-polariton channels: a signal that

Key Resonance Component Evaluation of Medium-Voltage Power Systems

Zhongguo dianli
Modal analysis techniques can capture the most comprehensive harmonic resonance data. Although current sensitivity analysis methodologies can rank the impact that each electronic component has on resonance, they fall short in precisely pinpointing the ...

Unified Harmonic Resonance

, 2005
This publication summarizes a series of experiments that reverse-engineer Nikola Tesla’s theoretical wireless-energy grid using acoustic analysis. By translating Tesla’s resonant 3-6-9 structure into controlled audio frequencies, the study demonstrates measurable harmonic coherence, phase stability, and geometric symmetry identical to Tesla’s predicted

Second harmonic resonance in a self-gravitating fluid column [PDF]

, 1981
The second-harmonic resonance of weakly nonlinear progressive waves in a self-gravitating cylindrical fluid column is examined. The steady state analysis of the dynamical equations governing the second harmonic resonance reveals that the general motion ...
