s of IWANASP, October 22 – 24, 2015, Lagos, Portugal A FAST FOURIER–GALERKIN METHOD SOLVING A BOUNDARY INTEGRAL EQUATION FOR THE BIHARMONIC EQUATION

When an extreme earthquake occurs, it is essential to detect the severe structural damage that affect the structural safety immediately. This paper proposes a method for quick earthquake damage detection/evaluation of reinforced concrete bridge columns. An intelligent sensor unit is developed that captures changes in the natural period of a bridge column by FFT of response acceleration recorded...

FFT mainly involved important role in electronics & communication field. The various types of FFT radix algorithm have analyzed and is to be modified in future. As a result of its exhaustive computational necessities, it occupies large area and consumes high power if implemented in hardware. Efficient algorithms are developed to improve its architecture.In this paper, we have conversed about FF...

Similar in nature to an image mosaic, a photo-stencil is a rendering of a binary target image by an arrangement of smaller binary stencil images. This paper presents a method for efficiently creating photo-stencil images, making use of the Fast Fourier Transform to speed up costly computations. The resulting photo-stencils are a new and interesting form of nonphotorealistic rendering.

This paper is concerned with the group-theoretical background of integral transforms and the role they play in signal processing on the sphere. An overview of topological groups, measure and representation theories, and an overview of the Windowed Fourier Transform and the Continuous Wavelet Transform are presented. A group-theoretical framework within which these transforms arise is presented....

We calculate the local Fourier transformations for a class of Q l -sheaves. In particular, we verify a conjecture of Laumon and Malgrange ([L] 2.6.3).

This paper describes the use of a resynthesis strategy in testing an auditory model, specifically a version of the DOMIN model. The steps by which the original speech is processed to produce a reduced, auditory (DOMIN) spectrum are described; subsequently, the reduced representation is used to produce resynthesised speech having the same auditory spectrum. In light ofthis equivalence, the exten...

This paper looks at one of the jewels of mathematics, the Fourier series / transform and briefly surveys its applications and looks at possible ways of enhancing the performance of the fast Fourier transform
