the kalut-e-ashrafa area is located in the north-east of ardakan area in central iran, yazd province. this area promises copper mineralization. the most of the minerals in this study area are silica-rich veins and veinlets. therefore, in order to identify geological formations with silica zones and to determine potential mineralization areas, aster images and remote sensing methods were used. a...

The uniaxial perfectly matched layer (PML) method uses rectangular domain to define the PML problem and thus provides greater flexibility and efficiency in dealing with problems involving anisotropic scatterers. In this paper we first derive the uniaxial PML method for solving the time-domain scattering problem based on the Laplace transform and the complex coordinate stretching in the frequenc...

Using the concept of steerable filters, it is possible to represent the rotation of a known template – and thus arbitrary orientations of lines or edges – as a linear combination of a fixed number of base filters, thus allowing a computationally efficient detection of 1D structures. In spite of their usefulness in many image processing areas, such structures exhibit one important drawback: Due ...

Quantum computational devices currently under development have the potential to accelerate data analysis techniques beyond ability of any classical algorithm. We propose application a quantum algorithm for detection unknown signals in noisy data. apply Grover's matched filtering, signal processing technique that compares number candidate templates. In comparison method, this provides speedup pr...
