It is a 2-degree-of-freedom (DOF) impulsive mechanical system that ... The procedure exploits a time-independent representation of a possible periodic solution via a virtual holonomic constraint. The ...

In this work we show that constraint qualifications based on the notion of constant rank can be understood as assumptions that ensure that the polar of the linear approximation ... Guignard's CQ holds ...

However, this method has the following defects: 1) Balasa's necessary condition for existence of the cell placement that satisfies the given constraints is incorrect; 2) some cells overlap ... method ...
