This unusual feature of human demography has been hypothesized to have evolved because of the "grandmother" effect, or the contributions that post-reproductive females make to the fitness of their children and(More)
Lumped parameter models can not sufficiently describe dynamics of many distributed systems, such as a continuous rotating shaft with bending. The finite element method is employed to embed distributed dynamics of rotating shafts with bending into constitutive laws of bond graphs resulting a finite element bond graph model. Defining the nodal displacements,(More)
