Image Analysis of Air Flow around a Ping-pong Ball

A ping-pong ball in left atrium.

Accepted 18 December 2017 DesCripTion Rheumatic heart disease (RHD) is much prevalent in low/middle-income country like India with the prevalence ranging from 0.2 to 1.1/1000 for RHD and from 0.0007 to 0.2/1000 for rheumatic fever. Factors that precipitate the formation of clot are atrial fibrillation (AF) rhythm, left atrial (LA) size, duration of symptoms, advanced age and severity of mitral ...

Modelling Coupled Heat and Air Flow: Ping-pong Vs Onions

Ping pong ball in the hefty heart: a case report.

We describe here a very unusual case of a large free floating left atrial thrombus due to critical mitral stenosis detected by incidental echocardiography, in whom peculiar symptoms and complications of ball thrombus were absent. The patent's only symptom was mild dyspnoea attributed to smoking. She had no syncope or arrhythmia induced embolic event. Owing to non-availability of cardiothoracic ...

A Receding Horizon Control for Lifting Ping-pong Ball

This paper proposes a control system for lifting a ping-pong ball without the use of a camera. The system measures the time of collision between a plate and a ball with a microphone. The control system must then be able to direct both the position and the velocity of a motor for each subsequent collision, even if the model contains uncertainty or modeling errors. To achieve this objective, an o...
