Determining robot location by cylindrical object shapes
Electronics Letters, 1992 A fast single-view approach to determining the robot location by using a known-radius cylindrical object is proposed. In the approach, no prerequisite intrinsic camera parameters are imposed, and only 3-D vector algebra is used in calculating the robot location. Therefore, alignment error can be avoided, the time of location determination is 0.3 s, and

3D direct and inverse solvers for eddy current testing of deposits in steam generator
, 2014 We consider the inverse problem of estimating the shape profile of an unknown deposit from a set of eddy current impedance measurements. The measurements are acquired with an axial probe, which is modeled by a set of coils that generate a magnetic field ...

Analytical Calculation of Cylindrical Shells in the Form of Second-Order Algebraic Surfaces
Structural Mechanics of Engineering Constructions and BuildingsWhen choosing the shape of a shell, one should strive for the boundary conditions to ensure momentless behavior of the shell. Second-order algebraic surfaces include three degenerate surfaces: parabolic, elliptic, and hyperbolic cylindrical surfaces, and
