Compressed sensing acceleration of radial 3‐D alternating Look‐Locker T1 mapping
Magnetic Resonance in Medicine, EarlyView.Abstract Purpose To determine how various compressed sensing (CS) models can accelerate alternating Look‐Locker T1$$ {T}_1 $$ mapping. Methods An alternating Look‐Locker acquisition was retrospectively accelerated by factors of 1–12. The data was reconstructed into 12 images with multiple CS models, which utilized combinations of spatial total ...

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT Nonlinearity in parallel compliance can be exploited to improve the performance of locomotion systems in terms of (1) energy efficiency, (2) control robustness, and (3) gait optimality; that is, attaining energy efficiency across a set of motions. Thus far, the literature has investigated and validated only the first two benefits.

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT In this article, the physics informed neural networks (PINNs) is employed for the numerical simulation of heat transfer involving a moving source under mixed boundary conditions. To reduce computational effort and increase accuracy, a new training method is proposed that uses a continuous time‐stepping through transfer learning.

Parameterized Local Reduced Order Model of Stimulated Volume Evolution in Reservoirs
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Real‐time simulation of large‐scale geomechanics problems, such as hydraulic dilation stimulation, is computationally expensive as they must span multiple spatial and temporal length scales, often including nonlinearities and thermo‐hydromechanical processes.

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT The stability analysis of a saturated soil slope subjected to seepage flow generated by rapid water level drawdown is investigated in this paper by means of the limit analysis kinematic approach. The analysis takes into account the inherent spatial variability of soil strength and permeability properties.
