T.C. Fan*, F.Y. Lin, C.S. Hwang, Ian C. Hsu Synchrotron Radiation Research Center, Hsinchu, Taiwan National Tsing Hua University, Hsinchu, Taiwan Abstract Several laboratories have used the pulsed wire method for magnetic field measurement. The acoustic wave distortion of the wire was observed. The limitations of this method were discussed. A pulsed wire system is under test in SRRC on an undul...

The paper addresses a crucial point in ultra-wideband (UWB) radio wave propagation, which is the spatial-temporal resolution of scattering objects into multiple frequency-dependent scattering centers. The effect contributes to the widely observed temporal dispersion of pulse-shaped transmit signals and their distortion, respectively. Particularly the latter is explained by (multiple) diffractio...

This paper presents an optimization of the electric power quality by designing a 9 steps multilevel power inverter, which adopts a multi-PWM optimized using genetic algorithms (GA), and minimizing Total Harmonic Distortion (THD) of the first 50 harmonics to about 0%. This optimization is considered an alternative technique because it reduces the expression used to quantify TDH numerically. Part...

We report experimental results of quantitative imaging in supersonic circular jets by using a monochromatic light probe. An expanding cone of light interrogates a three-dimensional volume of a supersonic steady-state flow from a circular jet. The distortion caused to the spherical wave by the presence of the jet is determined through our measuring normal intensity transport. A cone-beam tomogra...

We present a general proof of the distortion-correction theorem, that is, of the possibility of correcting wave distortion by the technique of optical phase conjugation. The proof is valid for fully vectorial nonparaxial propagation in the presence of a tensorial refractive-index perturbation and backscattering of the incident field.

The characterization of a Balanced Modulation and Detection analog optical link is presented. The link consists of a pair of low-biased DFB lasers modulated in a push-pull manner and a balanced photodetector. The measured link noise shows an enhancement of 15 dB around the laser threshold and large intermodulation distortion is observed due to imperfections in the half-wave rectification proces...

In this paper we apply a well-tested approximation of electron Coulomb distortion effects to the exclusive reaction (e, e ′ p) in the quasielastic region. We compare the approximate treatment of Coulomb distortion effects to the exact Distorted Wave Born Approximation evaluated by means of partial wave analysis to gauge the quality of our approximate treatment. We show that the approximate Møll...

1. Non-invasive recording techniques of the arterial pressure pulse will distort the arterial wall and may alter pulse wave measurements. We hypothesized that intersubject variability of these measurements would be reduced if recording forces were normalized to reflect individualized arterial occlusion forces. 2. In 10 normal male subjects (age 24 +/- 1 years), brachial, radial and finger arter...
