Higher-order kinematic analyses of a planar parallel robot based on screw theory
(2020)
This paper presents the higher-order kinematic analyses of a planar parallel robot, addressed by means of the theory of screws. The reduced velocity, acceleration, jerk and hyper-jerk state for the end-effector of robot ...
Trajectory-tracking control of a planar parallel robot using generalized predictive control with constraints
(2020)
This paper presents the generalized predictive control with constraints, implemented to a planar parallel robot in order to calculate and track the desired trajectory of the end-effector of this robot. The manipulator is ...
Kinematic and Workspace Analysis of Spherical 3RRR Coaxial Parallel Robot Based on Screw Theory
(2020-12-24)
A kinematic and workspace analysis of Spherical 3-RRR Coaxial Parallel Robot are developed in this paper. Position and orientation was determined through the inverse and forward kinematics using geometric and numerical ...
Fiscal impacts and cross-border effects of a change in state liquor policy
(2020-07)
This paper analyzes the economic effects of the 2012 change in liquor policy (Initiative 1183) in Washington State in the United States. This policy increased the availability of liquor but also increased taxes on liquor ...
A Novel Full Boundary Element Formulation for Harmonic Analysis of Elastic Membranes Coupled to Acoustics Fluids
(2020)
A novel full Boundary Element Formulation for the harmonic analysis of elastic membranes coupled to acoustics fluid is presented. The elastic membranes is modeled using the classical linear elastic pre-stretched membrane ...
