Rail defect detection by video cameras has recently gained much attention in both academia and industry. Rail image data has two properties. It is highly imbalanced towards the non-defective class and it has a large number of unlabeled data samples available for semisupervised learning techniques. In this paper we investigate if positive defective candidates selected from the unlabeled data can...

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Echocardiographic left ventricular (LV) global longitudinal strain (GLS) may be used to detect subclinical dysfunction in patients who have received cardiotoxic chemotherapy. However, some persons participating recreational sports, GLS at rest lower than normal, but normalizes after a short exercise test as soon resti...

The specific aim of this study was to quantify muscle activity while performing squat with technique variations. Eight healthy volunteers performed squats under 5 types of foot positions: neutral position, under a 10o descending wedge, under a 10o ascending wedge, under a 10o medial wedge and under a 10o lateral wedge. It was evaluated electromyographic data of vastus medialis oblique, vastus l...

Background: Human movement such as physical work, exercise and sport activities can be analyzed to determine kinetic (force) and kinematic (motion) characteristics. In the past, proper assessment of force variables requires force plates that can limit the types of activities performed. Additionally, large amounts of data are often generated, requiring often tedious and time-consuming analyses a...

T he squat is widely used as a staple exercise in resistance training programs. It is used by athletic and recreational populations alike to enhance both strength and hypertrophy of the lower-body musculature and improve functional performance (17). However, considerable controversy exists as to optimal squat depth, particularly as to whether deep squatting increases the risk of injury to the k...
