In this paper, an ideal cylindrical metamaterial invisibility cloak with infinite-length which its electric permittivity and magnetic permeability mapped to the Drude dispersion model is simulated. The sinusoidal plane waves with microwave frequencies used as sources. To this end, the dispersive finite-difference time-domain method (FDTD) used with Convolutional Perfectly Matched Layered (CPML)...

laguerre function has many advantages such as good approximation capability for different systems, low computational complexity and the facility of on-line parameter identification. therefore, it is widely adopted for complex industrial process control. in this work, laguerre function based adaptive model predictive control algorithm (ampc) was implemented to control continuous stirred tank rea...

This paper presents a new methodology for complete solution of general shape deep drawn parts. Evaluation of forming severity, estimation of the punch load and prediction of the thickness variation are the major results obtained in this work. The punch work is the summation of the homogenous work of flange deformation and bending and frictional works. To evaluate the strain energy of the flange...

Declustering and load-balancing are important issues in designing a high performance geographic information system (HPGIS) which is a central component of many interactive applications such as real-time terrain visualization. The current literature provides eecient methods for declustering spatial point-data. However, there has been little work towards developing eecient declustering methods fo...

graphs are denoted by capital roman letters and plane graphs by capital greek letters. If the graph G is isomorphic to the plane graph F, then F is a representation of G. If the edges of F are polygonal arcs (respectively straight line segments), then F is a polygonal arc representation (respectively straight line representation). A closed Jordan curve partitions the Euclidean plane into a boun...

This paper addresses the question of how the vertical structure of a product line relates to brand equity. Does the presence of “premium” or high-quality products in a product line enhance brand equity? Conversely, does the presence of “economy” or low-quality products in a product line diminish brand equity? Economists and marketing researchers refer to variation in quality levels of products ...

in this syudy a continuous bovine kidney cell line derived from a primary bovine kidney cells was established for the first time in iran. the cells were originating from two-day-old normal male calf of holstein breed. the cell cultures were continuously passaged following complete proliferation of primary cells. the specific properties or characteristics of the cell were defined using cytogene...

if we try to estimate the parameters of the ar process {xn} using the observed process {xn+zn} then these estimates will be badly biased and not consistent but we can minimize the damage using a robust estimation procedure such as gm-estimation. the question is does additive contamination affect estimates of “core” parameters in the infinite variance case to the same extent that it does in the ...
