A Geophysical Investigation in Which 3D Electrical Resistivity Tomography and Ground-Penetrating Radar Are Used to Determine Singularities in the Foundations of the Protected Historic Tower of Murcia Cathedral (Spain)

Remote Sensing
This study presents a procedure in which 3D electrical resistivity tomography (ERT) and ground-penetrating radar (GPR) were used to determine singularities in the foundations of protected historic towers, where space is limited due to their ...

Robust Control for High-Speed Visual Servoing Applications

International Journal of Advanced Robotic Systems, 2008
This paper presents a new control scheme for visual servoing applications. The approach employs quadratic optimization, and explicitly handles both joint position, velocity and acceleration limits.

Verification and Generation of Safe Straight Paths for a 4-DOF Spherical Manipulator

Tikrit Journal of Engineering Sciences, 2013
Sometimes in a manufacturing environment, a robotic arm is wanted to move in a straight path such as welding, painting and assembling. This straight path causes the manipulator to actuate all or most of its joints in the same time to track the path ...

Topological configurations of singularities for quadratic differential systems

, 2018
In [1-7] the authors proved that there are at least 1879 and at most 1880 di erent geometric con gurations of singularities of quadratic di erential systems in the plane. This classi cation is completely algebraic and done in terms of invariant polynomials and it is ner than the classi cation of quadratic systems according to the topological classi ...
