A new frequency domain method for the quantification of glottal volume velocity waveforms is presented in this study. This technique, called Parabolic Spectral Parameter (PSP), is based on fitting a parabolic function to a pitchsynchronously-computed spectrum of the estimated voice source. The PSP-algorithm gives a single numerical value that describes how the spectral decay of an obtained glot...

Recently, many numerical methods that are developed for the solution of electromagnetic problems have greatly benefited from the hardware accelerated scientific computing capability provided by graphics processing units (GPUs) and orders of magnitude speed-up factors have been reported. Among these methods, the finite-difference frequency-domain (FDFD) method as well can be accelerated substant...

Abstract—A multiresolution frequency domain (MRFD) analysis similar to the finite difference frequency domain (FDFD) method is presented. This new method is derived by the application of MoM to frequency domain Maxwell’s equations while expanding the fields in terms of biorthogonal scaling functions. The dispersion characteristics of waveguiding structures are analyzed in order to demonstrate t...

A method is presented to incorporate thin, lossy layers into a finite-difference frequency-domain model while retaining a coarse grid-spacing. This approach significantly reduces computational effort. The new method is validated by a comparison with analytical solutions. © 2004 Wiley Periodicals, Inc.

In this communication, several aspects of the implementation of a finite element method for the resolution of inverse problems (occurring in parameter identification) are exposed. Identification of a thermal parameter (diffusivity) at micrometric scale is obtained from observations of output signal due to a periodic input. Resolution of this identification problem is facilitated by the formulat...

This paper presents a graphics processing based implementation of the Finite-Difference Frequency-Domain (FDFD) method, which uses a central finite differencing scheme for solving Maxwell’s equations for electromagnetics. The radar cross section for different structures in 2D and 3D has been calculated using the FDFD method. The FDFD code has been implemented for the CPU calculations and the sa...

We propose a novel network traffic matrix decomposition method named Stable Principal Component Pursuit with FrequencyDomain Regularization (SPCP-FDR), which improves the Stable Principal Component Pursuit (SPCP) method by using a frequency-domain noise regularization function. An experiment demonstrates the feasibility of this new decomposition method. key words: Traffic Matrix, Stable Princip...

Frequency Domain Adaptive Filters (FDAFs) are an important subject of current research in digital signal processing. One of the main reasons is that FDAFs have the ability to reduce complexity, especially when the filter length becomes very large. In Adaptive Filter (AF) configurations a convolution and a correlation have t o be carried out. These operations can be done by using overlap methods...

A novel approach to motion estimation is presented. The scheme employs a multiresolution model of 2-D motion, in which the motion within local regions at di erent scales is described in terms of a six parameter a ne model. A frequency domain method is used to estimate the local a ne motion parameters and a coarsene tracking algorithm is used to determine the global motion eld. Results of experi...
