As usual in my walk trough Live Labs, i found “Pivot”, well what is it? in the own words from Live Labs, Pivot is a new way to interact with massive amount of data in the web using “Collections”. “Collections” are the heart the Pivot, they combine large groups of similar items on the Internet, so we can begin viewing the relationships between individual pieces of information in a new way. Conceptually, a collection is just like any other web content. There’s a set of files on a server, and a local...

Symbolic Lagrangian formulations of the equations of motion of tree structured constrained mechanical systems have the potential to be both more efficient and more numerically robust than formulations which use nonlinear kinematic constraint equations. D* is a program for efficiently computing symbolic derivatives, derive a simple recursive factorization of the Lagrangian equations of motion which, along with our extended implementation of the D* symbolic differentiation algorithm, yields empirically...
