To address the searching problem of protein conformational space in ab-initio protein structure prediction, a novel method using abstract convex underestimation ACUE based on the framework of evolutionary algorithm was proposed. Computing such conformations, essential to associate structural and functional information with gene sequences, is challenging due(More)
Analyses of the inverse and forward positions of a 3-DOF parallel mechanism (PM) along with two rotational DOFs and one translational DOF are presented in this paper. The module of this 2-PRU-PRRU PM is created, and the Jacobian of the 2-PRU-PRRU PM is derived. Boundary, local, and combined singularities are identified based on the Jacobian. The workspace(More)
