We report on cylindrical permanent-magnet structures that exploit the image effect in a surrounding circular soft-iron sheath. We present the theory for a general multipole ring, where the polarization direction = ( + 1) is a positive or negative integer, and is the angular coordinate. For the uniformly magnetized case = 1, a long cylindrical ring produces no field in its bore, and the field ou...

In cloaking, a body is hidden from detection by surrounding it by a coating consisting of an unusual anisotropic nonhomogeneous material. The permittivity and permeability of such a cloak are determined by the coordinate transformation of compressing a hidden 2D or cylindrical body into a line. Some components of the electrical parameters of the cloaking material (ε, μ) are required to have inf...

In the proposed work an analytical model of a p-channel dual material gate all around tunnel FET (DMGAA-TFET) is presented and its performance is compared with the conventional GAA-TFET. The electrostatic potential profile of the model is obtained using 2-D Laplace’s solution in the cylindrical coordinate system. A quantitative study of the drain current has been carried out using electric fiel...

In practical engineering, the use of Pauli algebra can provide a computational advantage, transforming conventional vector to straightforward matrix manipulations. this work, matrices in cylindrical and spherical coordinates are reported for first time their representing three-dimensional is discussed. This method leads unified representation 3D multivectors with algebra. A significant advantag...

This paper presents a new method for reconstructing paintings from component images. A set of monocular images of a painting from a straight homogeneous generalized cylinder is taken from various viewpoints. After deriving the surface localization in the camera coordinate system, the images are backprojected on the curved surface and attened. We derive the perspective distortion of the scene in...

In this paper it is shown a practical method wich lets evaluate the full set of robot configurations that produce collisions between the environment and the cylindrical manipulator. The method is based on a sound mathematical formalism so the feasibility of the results is guaranteed. The application of the formalism is performed by means of choosing a suitable coordinate functions, in the works...

A type of transformation media called α media is proposed by performing a direct transformation to the metric tensor of another kind of media, called seed media. Light rays in an α medium correlate to those in its seed medium through a simple displacement or rotation relation. Three types of commonly encountered anisotropic media are covered by the concept of α media: (1) media of slab shape, h...

We derive the elastic properties of a cylindrical cloak for in-plane coupled shear and pressure waves. The cloak is characterized by a rank 4 elasticity tensor with 16 spatially varying entries which are deduced from a geometric transform. Remarkably, the Navier equations retain their form under this transform, which is generally untrue [Milton et al., New J. Phys. 8, 248 (2006)]. We numericall...

Modeling turbulent convection in the melt is the most di cult part of the simulation of the transport processes in the growth of large-diameter silicon crystals by the Czochralski (CZ) process. We report the application of hybrid nite-element/ nitevolume methods for the integrated modeling of turbulence in the melt and heat transfer by conduction, convection and radiation throughout the CZ syst...
