ALGEBRAIC SOLUTION OF MODELS WITH A QUICK THRUST BY MEANS OF A COMPUTER ALGEBRA SYSTEM.

Quick thrusts or pushes do appear in a number of engineering situations which are usually modeled by means of delta generalizad functions. Some of these may be properly manipulated with computer algebraic systems such as Mathematica. The aim of this note is showing how this may be carried out in a number of specific examples corresponding to some dynamic systems. [ABSTRACT FROM AUTHOR]
