Classification of UAV-to-Ground Vehicles Based on Micro-Doppler Signatures Using Singular Value Decomposition and Deep Convolutional Neural Networks

IEEE Access, 2019
Attack from the unmanned aerial vehicles (UAVs) has been the main means of high-precision strike. Therefore, classifying ground vehicles from the UAV with high accuracy is of great significance.

Evaluation of systemic consequences of brachycephalic obstructive airway syndrome in dogs

Veterinary Record, EarlyView.
Abstract Background Brachycephalic obstructive airway syndrome (BOAS) results from upper airway anatomical abnormalities and may cause systemic effects depending on severity. Methods A prospective, case‒control and observational study was conducted.

Sonar micro-Doppler effect induced by ship oscillatory motion in waves: Phenomenon, model, and experimentation [PDF]

JASA Express Letters
Traditional research attributes the modulated sidebands of ship radiation line-spectrum signals to reflections off rough ocean surfaces, but the Doppler effect caused by vessel motion may also contribute.

The Evolution in Understanding the Physiological Causes of Dyspnoea in Large Hiatal Herniation: A Narrative Review

ANZ Journal of Surgery, EarlyView.
ABSTRACT Background The symptomatology of large hiatus hernia (LHH) has been historically poorly understood, with cardiorespiratory symptoms caused by LHH being underappreciated by clinicians. This study reports on the mechanisms of dyspnoea in LHH through a historical review of symptoms and evolved physiological literature, discussing likely causation.

DeepActivity: a micro-Doppler spectrogram-based net for human behaviour recognition in bio-radar

The Journal of Engineering, 2019
The movements of the human body and limbs result in unique micro-Doppler signatures, which can be exploited for classifying human activities. In this work, the authors propose a Convolutional Gated Recurrent Units Neural Network (CNN-GRU) to classify ...

Physiological cardiotocography interpretation and neonatal morbidity: A historical pre–post cohort study in a tertiary perinatal center

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
In this historical pre–post cohort study, the implementation of physiological cardiotocography (PCI) interpretation was associated with reduced neonatal morbidity, neonatal acidosis, and neonatal unit admission. Adjusted cesarean section rates did not increase, supporting PCI as a promising approach to intrapartum fetal surveillance.

Three-dimensional reconstruction of space rotating target based on narrow-band radar networks

The Journal of Engineering, 2019
The micro-motion of space target is an important signature for classification and recognition, which has received great attention. Based on the micro-Doppler signals from narrow-band radar networks, this study proposes a three-dimensional reconstruction ...

Mitral regurgitation and decompensated heart failure in a young pregnant pony mare: An aetiological challenge

Equine Veterinary Education, EarlyView.
Summary A 4‐year‐old, 6‐month pregnant, Welsh pony mare presented with severe acute clinical signs including depression, anorexia, pale mucous membranes, tachycardia with a grade 4/6 holosystolic murmur and moderate expiratory dyspnoea with diffuse wheezes. There was no evidence of placentitis or fetal distress.
