Aerial drones have improved significantly over the recent decades with stronger and smaller motors, more powerful propellers, and overall optimization of systems. These improvements have consequently increased top speeds ...

Cardiac valves regulate blood flow in the heart by maintaining the circulation in a single direction. When these valves have a disability, it can lead to serious heart problems; being responsible for 30% of cardiac surgery ...

Aeroelastic stability analysis plays an important role during the development of new aircraft. It can affect flight envelope, the aircraft geometry, and the design of components, like control surface actuators, for example. ...

Most of the established procedures for analysis of aeroelastic flutter in the development of aircraft are based on frequency domain methods. Proposing new methodologies in this field is always a challenge, because the new ...

Cardiovascular diseases are the leading causes of death, accounting for more than 17.6 million cases worldwide. Among the main diseases, it can be highlighted the problems related to malfunctioning of heart valves such as ...

The present work describes an alternative methodology for identification of aeroelastic stability in a range of varying parameters. Analysis is performed in time domain based on Lyapunov stability and solved by convex ...
