    • The Composition of Bennett’s Hyperboloids From the Loop Itself 

      J. Eddie Baker (The American Society of Mechanical Engineers (ASME), 2004)
      Despite the tidiness with which the Bennett linkage can be related geometrically to its associated quadric surfaces, the corresponding algebraic determinations have generally turned out to be ...

    • The 3-RRS Wrist: A New, Simple and Non-Overconstrained Spherical Parallel Manipulator 

      Raffaele Di Gregorio (The American Society of Mechanical Engineers (ASME), 2004)
      Orientating a rigid body without changing its position is required in many technical applications. This manipulation task is accomplished by manipulators (spherical manipulators) that are just ...

    • Multi-Objective Optimization Using Asynchronous Distributed Applications
