We report on the motion of a spinning sleeping top an inclined plane. Below critical inclination angle tops are force free. The trajectory weakly planes in adiabatic limit is invariant angular frequency and thus under rescaling time, however not time reversal. stationary characterized by its Hannay type geometric to plane horizontal direction. At larger inclinations becomes unstable accelerates...

Traditional plane alignment techniques are typically performed between pairs of frames. In this paper we present a method for extending existing two-frame planar-motion estimation techniques into a simultaneous multi-frame estimation, by exploiting multi-frame geometric constraints of planar surfaces. The paper has three main contributions: (i) we show that when the camera calibration does not ...

In recent years, the optimization of multi-objective service composition in distributed systems has become an important issue. Existing work makes a smaller set Pareto-optimal solutions to represent Pareto Front (PF). However, they do not support complex mapping quality (QoS) objective space, thus having limitations providing representative solutions. We propose enhanced differential evolution ...

Renishaw Ballbar QC20–W is primarily intended for diagnostics of CNC machine tools, but it also used in connection with industrial robots. In the case standard measurement, when measuring plane parallel to robot base, not all joints move. The purpose experiments present article was verify hypothesis motion desired circular path placed on an inclined plane. first part conducted established confi...

This paper proposes a method to measure the inclined angle of an objective image based on the most frequent edge direction. This paper also describes a relation between the measured inclined angles by the proposal method and the visual inclined angles. An edge direction is changed according to the inclination of an objective image. The most frequent edge direction is supposed to show the global...

In the title compound, C(22)H(15)BrO(4), the bromo-benzene ring is inclined at dihedral angles of 23.87 (11) and 52.37 (11)° with respect to the planes of the two benzene rings. The two benzene rings of the biphenyl unit form a dihedral angle of 49.08 (11)°. In the crystal, mol-ecules are linked into [100] chains by C-H⋯O hydrogen bonds.

In the title compound, C(21)H(22)N(2)O(2), the mean plane of the pyrazole ring makes dihedral angles of 18.80 (12) and 77.13 (5)°, respectively, with the mean planes of the phenyl and tert-butyl-benzyl rings. The carboxylate group is inclined at 8.51 (14)° with respect to the pyrazole ring. The crystal structure displays inter-molecular O-H⋯O hydrogen bonding, generating centrosymmetric dimers.

In the mol-ecule of the title sulfonamide compound, C(13)H(11)NO(4)S, the dihedral angle between the planes of the benzene ring and the carboxyl substituent group is 6.7 (4)°. The two aromatic rings are inclined at 45.36 (15)° to one another. In the crystal, adjacent mol-ecules are linked via classical inter-molecular N-H⋯O and O-H⋯O, and non-classical C-H⋯O hydrogen bonds, which stabilize the ...
