The Development and Challenges of PET/MRI Dual‐Modality Imaging Probes—An Update

Journal of Magnetic Resonance Imaging, Volume 62, Issue 5, Page 1245-1259, November 2025.
ABSTRACT The integration of Positron emission tomography (PET) with Magnetic resonance imaging (MRI) combines the functional imaging capabilities of PET with the high‐resolution anatomical detail of MRI, creating a synergistic platform for advanced diagnostic imaging and image‐guided therapies. Central to the success of this dual‐modality system is the

Comparison between Model Predictive (MPC) and Model Reference Adaptive Controllers (MRAC) for Electrohydraulic Steering System Implemented as Real-Time Simulink® Program

IOP Conference Series: Materials Science and Engineering, 2020
Abstract The purpose of the article is to investigate tracking performance of steering cylinder when controlled with two nonlinear controllers. The system under study is a laboratory electrohydraulic steering test rig. Two controls strategies are examined - model reference adaptive control (MRAC) and model predictive control (MPC).

Tube model reference adaptive control

, 2013
By using the concept of on-line goal adaptation, we develop a new paradigm of performance shaping in MRAC. The general idea is to replace the single reference model generated trajectory in classical adaptive design with a tube reference model.
