Abstract: The workspaces and kinematic characterization of serial chain manipulator geometries and the geometric optimization have been studied extensively. Much less is known about workspaces for manipulation ...

Abstract: This paper addresses the instantaneous kinematics of robotic manipulators which have an in-parallel scheme of actuation. Hybrid geometries which require both serial and parallel actuation are also ...

Abstract: A process to produce a family of novel materials from polycarbonate, having a microcellular structure, is described. The process utilizes the high solubility of carbon dioxide in polycarbonate ...

Abstract: A numerical analysis procedure using the boundary-integral equation method is presented for the solution of problems of time-dependent inelastic deformation in planar metallic bodies. The formulation ...

Abstract: A sequential approximation algorithm is presented here that is particularly suited for problems in engineering design and structural optimization, where the number of variables is very large and ...

Abstract: The spherical five bar parallel drive linkage is investigated for use as a spherical manipulator or as a pointing mechanism. The direct and inverse kinematics are derived for a general 5-R ...

Abstract: Heterogeneous objects, composed of different materials, are increasingly being used in engineering applications. Also, a new fabrication method called Layered Manufacturing (LM) has shown potential ...

Abstract: This paper describes a hybrid mobility system that combines the advantages of both legged and wheeled locomotion. The legs of the hybrid mobility system permit it to surmount obstacles and ...

Abstract: A new inter-pulse frequency-diverse technique is introduced for weather radar second-trip suppression and retrieval. Inter-pulse coding is widely used for second trip suppression or cross-polarization isolation. Here, a ...

Abstract: Several newer constitutive relations have recently been proposed for describing the mechanical behavior of metals and alloys under elevated temperature creep conditions. A salient feature of the ...
