A retraced spiral strategy with semi‐automatic deblurring for volumetric thermometry

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose To develop a 3D MRI‐thermometry technique for transcranial MR‐guided focused ultrasound (MRgFUS). Methods A stack of retraced in‐out (RIO) spirals was incorporated into a 3D, RF‐spoiled, gradient recalled echo (GRE) sequence with a minimized energy deblurring strategy. Bloch simulations examined isochromat precession during RIO readout

ANN‐Based Green's Function Approach for Reservoir Geomechanics

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Green's functions have been a tool to analyze important reservoir geomechanics effects like subsidence, compaction, well closure, and permeability variation. However, the classical Green's function is related to linear elastic, homogenous, and geometrically simplified media.

Exact Methods for the Split Delivery Vehicle Routing Problem With Two‐Dimensional Loading Constraints

Networks, EarlyView.
ABSTRACT The Split Delivery Vehicle Routing Problem with Two‐dimensional Loading Constraints (2L‐SDVRP) integrates vehicle routing, split delivery, and two‐dimensional packing constraints. In the 2L‐SDVRP, customers can be served by multiple vehicles, and their demands consist of different two‐dimensional rectangular items that must be packed in the ...

Sensitivity‐Based Distributed Model Predictive Control for Non‐Linear Systems Under Inexact Optimization

Optimal Control Applications and Methods, EarlyView.
This article introduces a novel sensitivity‐based algorithm for nonlinear distributed model predictive control. The algorithm requires only local computations with one neighbor‐to‐neighbor communication step per iteration and exhibits a linear order of convergence under suitable conditions.
