Wide binary stars with separation greater than about 2000 astronomical units are interesting natural laboratories that allow a direct probe of gravity at low acceleration weaker than about 1 ...

To eliminate the reliance on direct angular velocity measurements, a cascaded estimation scheme is proposed, employing indirected angular velocity estimation through a single vector measurement that ...

Abstract: This paper addresses the attitude tracking control problem of liquid-filled spacecraft in the presence of angular velocity constraints and limited control torque. Significant challenges ...

Objective Concussion is a prevalent brain injury in sport and the wider community. Despite this, little research has been conducted investigating the dynamics of impacts to the unprotected human head ...

The momentum of an object is the product of its mass and its velocity. There is an equivalent law for rotating objects. A rotating object tends to remain rotating with a constant angular momentum ...
