Published: June 2011

In this article, we propose a massively parallel, real-time algorithm for the estimation of the dynamic phase map of a vibrating object. The algorithm implements a Fourier-based quadrature transform and temporal phase unwrapping technique. CUDA, a graphic processing unit programming architecture was used to implement the algorithm. It was tested on a fringe pattern sequence using three devices with different capabilities, achieving a processing rate greater than 1600 frames per second (fps).

Article Synopsis
  • * The model uses the differential quadrature finite element method (DQFEM) based on first-order shear deformation theory (FSDT) and has been validated through comparisons with existing literature, ABAQUS software, and experimental results.
  • * The research aims to understand how different structural properties and boundary conditions affect the vibration frequencies of these plates, providing insights for the design and stability of lightweight rotor structures in applications like aircraft engines.

Article Synopsis
  • The paper introduces a new theoretical probability distribution model for the peak-to-average power ratio (PAPR) specifically for digital sub-carrier multiplexing (DSCM) systems, which is a novel idea in existing literature.
  • It proposes an innovative interleaved discrete Fourier transform spread DSCM (I-DFT-S-DSCM) method that creates reversible correlations among subcarriers to effectively reduce PAPR.
  • Results from a simulation using a 64-GBaud 16 quadrature amplitude modulation (16-QAM) DSCM system show that the I-DFT-S-DSCM scheme can lower PAPR by up to 1.44 dB and improve overall system performance, including bit error rate (BER),

This paper examines the thermo-hydro-mechanical (THM) coupling behavior of layered transversely isotropic media under axisymmetric and plane strain conditions by utilizing the transformed differential quadrature method (TDQM), taking groundwater into consideration. Initially, the coupled governing equations of layered transversely isotropic media in multi-dimensional coordinate systems are established with considering the influence of groundwater levels. Subsequently, appropriate integral transform methods are applied to derive ordinary differential equations under different coordinate systems.

The development of numerous diseases, such as renal cyst, cancer, and viral infection, is closely associated with the pathological changes and defects in the cellular peripheral brush. Therefore, it is necessary to develop a potential new method to detect lesions of cellular peripheral brush. Here, a piecewise linear viscoelastic constitutive model of cell is established considering the joint contribution of the peripheral brush and intra-cellular structure.

Demonstration of metaplectic geometrical optics for reduced modeling of plasma waves.

Section for Plasma Physics and Fusion Energy, Department of Physics, Technical University of Denmark, DK-2800 Kgs. Lyngby, Denmark.

The Wentzel, Kramers, and Brillouin (WKB) approximation of geometrical optics is widely used in plasma physics, quantum mechanics, and reduced wave modeling, in general. However, it is well-known that the approximation breaks down at focal and turning points. In this paper, we present an unsupervised numerical implementation of the recently developed metaplectic geometrical optics framework, which extends the applicability of geometrical optics beyond the limitations of WKB, such that the wave field remains finite at caustics.
