We measured the second-harmonic signal generated by high-quality zinc oxide single crystals. Comparing this signal with that generated by single-crystal quartz, used as a standard, we found that the components of the second-order susceptibility tensor differ somewhat from the values reported earlier. Measurements of two zinc oxide single crystals with different orientations yield similar results.
in this thesis a calibration transfer method is used to achieve bilinearity for augmented first order kinetic data. first, the proposed method is investigated using simulated data and next the concept is applied to experimental data. the experimental data consists of spectroscopic monitoring of the first order degradation reaction of carbaryl. this component is used for control of pests in frui...
There is a kind of composite materials made up of noble metal nanoparticles (such as gold, silver, copper) and a dielectric material (such as silica) with unique properties. In this paper, using Strong Permittivity Fluctuation Theory (SPFT) method, the coefficient of effective permittivity and the effective susceptibility coefficient are calculated for combining glass with metal nanoparticles, ...
استفاده از معیارهای پایا در طراحی الگوریتمها و بررسی عملکرد آنها جایگاهی ویژه در دانش مخابرات و کنترل دارد. یک معیار مناسب در طراحی الگوریتمهای وفقی پایا نرم h می باشد. با استفاده از این نرم و با در نظر گرفتن سرعت تغییرات پارامتر در یک مدل کاربردی دو الگوریتم در رده الگوریتمهای lms و (least mean squared) و (normalized lms) nlms با عنوانهای (second order lms) slms و (second ...
Nonresonant second harmonic generation (SHG) phase and amplitude measurements obtained from the silica-water interface at varying pH values an ionic strength of 0.5 M point to existence a nonlinear susceptibility term, which we call ?X(3), that is associated with 90° shift. Including this contribution in model for total effective second-order produces reasonable estimates interfacial potentials...
