Geometric algebra is used in an essential way to provide a coordinatefree approach to Euclidean geometry and rigid body mechanics that fully integrates rotational and translational dynamics. Euclidean points are given a homogeneous representation that avoids designating one of them as an origin of coordinates and enables direct computation of geometric relations. Finite displacements of rigid b...

We present an interface between a deformable body mechanics model and a rigid body mechanics model. What is novel with our approach is that the physical representation in both the models is the same, which ensures behavioral correctness and allows great flexibility. We use a massspring representation extended with the concept of volume, and thus contact and collision. All physical interaction o...

679 mindful of instances where the trauma was too severe or where psychiatric disease renders therapeutic interference ineffectual. and problems of infancy and adolescence. Fully realizing the intricacy of the interrelation of personality factors and the difficulties in communicating such complexes, it is with regret, rather than with destructive criticism, that I recognize many lacunae in the ...
