This study is on how leg utilisation may affect skiing efficiency and performance in double-poling ergometry. Three experiments were conducted, each with a different style of the double-poling technique: traditional with small knee range-of-motion and fixed heels (TRAD); modern with large knee range-of-motion and fixed heels (MOD1) and modern with large knee range-of-motion and free heels (MOD2...
A silica/electro-optic (EO) polymer phase modulator is proposed for millimeter-wave (MMW) radiation receiver with the use of a bowtie antenna. Waveguide design optimization is presented for a waveguide with an EO polymer core and silica/solgel cladding. Electrode effects on the insertion loss and poling efficiency are also analyzed and conditions for low-loss and high poling efficiency establis...
The aims of this study were to compare performance with physiological and perceptual responses on steep uphill inclines between double poling diagonal stride investigate the effects pole length when poling. Eight male, competitive cross-country skiers (22 ± 1.1 yrs, peak oxygen uptake (VO<sub>2peak</sub>) in stride: 69.4 5.5 ml·kg<sup>-1</sup>·min<sup>-1</sup>...
A difunctional NLO Azo-Dye chromophore has been synthesized and polymerization has been performed with a comonomer bearing a side-chain epoxy group. Deposition of the polymer on glass substrates was performed by spincoating, resulting in uniform films up to 2 μm thickness. The orientation of the chromophore was performed under a “pinto-plane” positive corona discharge followed by a heat-treatme...
Type I (GE124) and Type II (KV) fused silica were thermally poled in a vacuum and in air under identical poling conditions. Second-order nonlinear (SON) strength and nonlinear depth were found all to be the same. Samples were then stored in high and low humidity to study their SON stability. The SON of poled GE124 was stable over time despite different poling atmospheres and humidity in storage...
We present a multi-scale modelling framework to predict the effective electromechanical behavior of ferroelectric ceramics and thin films. This paper specifically focuses on the mesoscopic scale and models the effects of domains and domain switching taking into account intergranular constraints. Starting from the properties of the single crystal and the pre-poling granular texture, the theory p...
