Sampling of non‐Gaussian Ensemble Average Propagators for the simulation of diffusion magnetic resonance images

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose (a) To design a methodology for drawing random samples of any Ensemble Average Propagator (EAP) (b) to modify the KomaMRI simulator to accommodate them as realistic spin movements to simulate diffusion MRI (dMRI) and (c) to compare these simulations with those based on the Diffusion Tensor (DT) model.

MR sequence design to account for nonideal gradient performance

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose MRI systems are traditionally engineered to produce close to idealized performance, enabling a simplified pulse sequence design philosophy. An example of this is control of eddy currents produced by gradient fields; usually these are compensated by pre‐emphasizing demanded waveforms.

Cartesian MaxGIRF: Model‐based EPI reconstruction incorporating gradient nonlinearity and concomitant field effects

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose Lower field strength scanners with large bore size or complex geometries, and scanners with stronger gradient systems experience increased gradient nonlinearity and concomitant fields, each of which causes distortions in EPI. Current correction approaches based on image‐domain interpolation introduce undesirable spatial blurring.

Launch Uncertainty Analysis Under Barrel Erosion Using Experiments and Random Matrix Theory

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The effects of barrel erosion on artillery firing performance have long been a subject of concern, but its effect on launch uncertainty has yet to be investigated. This article explores the influence of barrel erosion on the interior ballistic mechanical properties and launch disturbances.

A Data‐Driven Approach to Integrated Adaptive Morphing and Guidance for Cruise Missiles

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT To address the complex coupling between aerodynamic characteristics and guidance control for morphing flight missiles, this study proposes a data‐driven approach to integrated adaptive morphing and guidance. Firstly, an aerodynamic surrogate model is constructed using a fully connected neural network (FCNN), mapping the configuration ...
