Topological Synthesis of Compliant Mechanisms Using Spanning Tree Theory
(The American Society of Mechanical Engineers (ASME), 2005)This paper introduces the spanning tree theory to the topological synthesis of compliant mechanisms, in which spanning trees connect all the vertices together using a minimum number of edges. ... -
A Quadratic Programming Formulation for the Design of Reduced Protein Models in Continuous Sequence Space
(The American Society of Mechanical Engineers (ASME), 2005)The notion of optimization is inherent in the design of a sequence of amino acid monomer types in a long heteropolymer chain of a protein that should fold to a desired conformation. Building ... -
A Three Degree-of-Freedom Model for Self-Retracting Fully Compliant Bistable Micromechanisms
(The American Society of Mechanical Engineers (ASME), 2005)A three degree-of-freedom (3DOF) pseudo-rigid-body model (PRBM) has been developed and used in the design of a new class of self-retracting fully compliant bistable micromechanism (SRFBM). The ... -
Force Analysis of a Vibratory Bowl Feeder for Automatic Assembly
