A Scale-Space Approach to Landmark Constrained Image Registration
Adding external knowledge improves the results for ill-posed problems. In this paper we present a new multi-level optimization framework for image registration when adding landmark...

Transformation of optimal control problems with a state constraint avoiding interior boundary conditions
— A well–known problem in constrained optimal control is the presence of interior boundary conditions for constrained arcs which require a–priori knowledge of the optimal sol...

On Clamping Planning in Workpiece-Fixture Systems
Deformation at contacts between the workpiece and locators/clamps resulting from large contact forces causes overall workpiece displacement, and affects the localization accuracy o...

Numerical optimization in hybrid symbolic-numeric computation
Approximate symbolic computation problems can be formulated as constrained or unconstrained optimization problems, for example: GCD [3, 8, 12, 13, 23], factorization [5, 10], and ...

Synthesis of Constrained nR Planar Robots to Reach Five Task Positions
— In this paper, we design planar nR serial chains that provide one degree-of-freedom movement for an end-effector through five arbitrarily specified task positions. These chai...
