Machine Learning‐Based Risk‐Adjusted CUSUM Control Chart for Monitoring Readmission Rate Following PTBD Catheter Placement

Quality and Reliability Engineering International, Volume 42, Issue 3, Page 933-949, April 2026.
ABSTRACT Percutaneous transhepatic biliary drainage (PTBD) catheter placement is known to have a high readmission rate. This work focuses on monitoring the change in readmission rate after a new clinical paradigm for post‐procedural care is implemented for the PTBD procedures.

Open‐Set Recognition of Radar One‐Dimensional Range Profiles Based on Attention Mechanism and Multi‐Task Joint Training

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
To address the issues in radar automatic target recognition (RATR) based on high‐resolution range profiles (HRRP)—specifically, the inability of closed‐set methods to handle unknown categories and the limitation of conventional open‐set methods that can only reject unknown categories without further subdivision—this paper proposes the MHA–CoST open‐set

Characterisation and Classification of Resident Space Objects Using Radar Networks

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This paper describes a simulated environment for generating Inverse Synthetic Aperture Radar (ISAR) images and interferometric point clouds using a three‐receiver radar configuration, along with the creation of extensive datasets to train and evaluate deep learning models under varying Signal‐to‐Noise Ratio (SNR) conditions. Findings show that modified

3‐D Micro‐Motion Parameters Estimation of Smoothly Precession Cone‐Cylinder Targets Based on Monostatic Radar

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This article proposes a method that a single radar was used for the first time to estimate the micromotion parameters and geometric information of a precession cone‐cylinder target with unknown precession angle by utilising the relationship between the curves of each scattering point in high‐resolution range profile (HRRP) and time–frequency diagram ...

Dynamic Compressed HRRP Generation for Random Stepped-Frequency Radar Based on Complex-Valued Fast Sequential Homotopy [PDF]

, 2014
Compressed sensing has been applied to achieve high resolution range profiles (HRRPs) using a stepped-frequency radar. In this new scheme, much fewer pulses are required to recover the target’s strong scattering centers, which can greatly reduce the ...
