Morphological features of pterygoid hamulus and its clinical significance;

Objective: To study the morphology of pterygoid hamulus and its relation with surrounding structures,providing anatomy data for clinical diagnosis and treatment of pterygoid hamulus syndrome.

It deals with the deformation by force and the stress distribution of "s" hooks which are used in lifting membrane panels.

Noise reduction mechanism of non-smooth leading edge of owl wing;

The wings of projectile provide the lift, control the direction and keep the stability of flying.

Based on CFD technique,three different shapes rudder/wing were designed which consulted some rudders/wings of Autonomous Underwater Vehicles(AUV)mother models.
