Human Motion Recognition With Limited Radar Micro-Doppler Signatures
IEEE Transactions on Geoscience and Remote Sensing, 2021 The performance of deep learning (DL) algorithms for radar-based human motion recognition (HMR) is hindered by the diversity and volume of the available training data. In this article, to tackle the issue of insufficient training data for HMR, we propose an instance-based transfer learning (ITL) method with limited radar micro-Doppler (MD) signatures ...

International Journal of Gynecology &Obstetrics, EarlyView.Abstract The labor care guide (LCG) is a new tool for monitoring labor, introduced to replace the partograph, which had been used improperly and inconsistently across various contexts. Early research suggests that healthcare practitioners view the LCG as a tool that enhances the quality of care during labor and delivery.

Renal screening sonography—A comparative study in a Portuguese basic emergency service
Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 8-16, March 2025.Renal sonography screening aids in clinical decision‐making for patients with suspected renal colic. This study intends to compare the accuracy and pertinence of sonographic findings obtained by a sonographer in a Basic Emergency Service (BES) with that of radiologists at Referral Hospital (RH) in Portugal. Renal sonography screening was able to detect

Bistatic human micro-Doppler signatures for classification of indoor activities [PDF]
2017 IEEE Radar Conference (RadarConf), 2017 This paper presents the analysis of human micro- Doppler signatures collected by a bistatic radar system to classify different indoor activities. Tools for automatic classification of different activities will enable the implementation and deployment of systems for monitoring life patterns of people and identifying fall events or anomalies which may be
