Constant Propagation Through Array Variables

open access: yes, 1999
Constant propagation can provide significant improvements in program speed, both by directly enabling optimizations such as constant folding and algebraic simplication and by providing information that increases the effectiveness of other compile-time ...

A conventional method for acoustic impedance eduction in a flow duct based on the straight forward method

open access: yesNihon Kikai Gakkai ronbunshu, 2019
A conventional method for acoustic impedance eduction in a flow duct is proposed. This method is based on the straight forward method. Assuming that a single mode propagates in the duct and the flow is uniform, propagation constants for both forward and ...

Numerical Modeling and De-Embedding of Non-Planar Periodic Guided-Wave Structures via Short-Open Calibration in 3-D FEM Algorithm

open access: yesIEEE Access, 2018
In this paper, a numerical short-open calibration (SOC) technique is presented to numerically model and de-embed a variety of non-planar periodic guided-wave structures based on the 3-D full-wave finite element method (FEM).

Use of Two Open-Terminated Coaxial Transmission-Lines Technique to Extract the Material Relative Intrinsic Parameters

open access: yesIEEE Access, 2020
We have presented an open-terminated transmission-line technique, based on the use of two substantially identical circular coaxial structures with different lengths, to extract the material relative permittivity εr.

TM POLARIZED SURFACE WAVES PROPAGATING ALONG THE SURFACE OF A PHOTOREFRACTIVE CRYSTAL WITH NONLINEAR SELF-FOCUSING COATING

open access: yesКонденсированные среды и межфазные границы, 2019
Objective. A model of a composite waveguide structure based on a photorefractive crystal with a diffusion mechanism with a nonlinear self-focusing coating is considered. The Kerr effect is realized in the coating when the refractive index depends on the

Random fractional Fourier transform : stochastic perturbations along the axis of propagation

open access: yes, 1999
The fractional Fourier transform (FRT) is known to be optically implementable with use of a medium with a perfect radial quadratic-index profile. Using the quantum-mechanical operator formalism, we examine the effects on the FRT action of such a medium

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Constant Propagation on the Value Graph: Simple Constants and Beyond [PDF]

open access: yes, 2000
We present a new algorithm for constant propagation (CP), which works on the value graph of a program. This algorithm combines the (1) efficiency of the sparse CP-algorithms of Reif and Lewis, Ferrante and Ottenstein, and Weg man and Zadeck with the (2) conceptual simplicity of their classic conventional counterparts of Kildall, and Kam and Ullman ...
