A Frequency Decomposition Time Domain Model of Broadband Frequency-Dependent Absorption
frequency decomposition bandpass Gauss filter broadband ultrasound frequency-dependent attenuation time domain
2010/10/22
This study aims to extend the time-domain model for the frequency-dependent attenuation of a single frequency excitation to a broadband excitation via a finite frequency decomposition. Our model satis...
Quantification of the CARI breast imaging sensitivity by 2D/3D numerical time-domain ultrasound wave propagation
Breast cancer CARI technique Ultrasound Time-domain wave propagation Finite element time domain method
2010/10/22
Breast imaging systems must recognize very small lesions at early stage of detection in order to save lives and reduce costs. The clinical amplitude–velocity reconstruction imaging (CARI), a recent br...
Dual reciprocity BEM applied to transient elastodynamic problems with differential quadrature method in time
Elastodynamics Dual reciprocity BEM Differential quadrature method Time-stepping integration Lyapunov matrix equation
2010/10/22
This paper is concerned with numerical analysis of the transient elastodynamic problems by the dual reciprocity BEM (DRBEM) in space combined with the di€erential quadrature method (DQM) in time....
Coupling dual reciprocity BEM and differential quadrature method for time-dependent diffusion problems
Dual reciprocity BEM Differential quadrature method Transient diffusion Lyapunov matrix equation
2010/10/22
This paper presents the very ®rst combined application of dual reciprocity BEM (DRBEM) and di€erential quadrature (DQ) method to time-dependent di€usion problems. In this study, the DRBE...
