Wavelength ratio

The thermal healing has been studied most extensively for one-dimensional gratings. Above roughening, the gratings acquire, for small amplitude to wavelength ratios, a sinusoidal form, as predicted by the classical continuum theory of Mullins and confirmed by experimenf-s and Monte Carlo simulations. - The decay of the amplitude is, asymptotically, exponential in time. This is true for both evaporation dynamics and (experimentally more relevant) surface diffusion.

Fig. 3. Theoretical streamwise velocity profiles for a 15 Hz capillary-gravity wave. Curves are shown for an ideal inviscid flow, a real flow with zero viscoelasticity, and a surfactant flow with a finite viscoelasticity. All profiles are taken under a wave crest. The wave amplitude wavelength ratio is 1 20...

K and 750 p K is about 400 and the de Broglie wavelength ratio factor varies inversely with temperature. Therefore, in order that the cross section ratio be consistent with low- and high-temperature experiments,...

Note that, in this case, the wavelength ratio fi is uniquely determined by the set of (Cp, G). 

An example of the reconstructed image in the PCR method is presented in Fig. 4, where we calculated the wavelength ratio and the direction vector e, for each grating component Gj by using Eqs. (9) and (10), neglecting off-Bragg diffraction. In this simulation, we assumed... 

Note that if the grating component Go and the wavelength ratio //o are given, then Cp and eao have only one free parameter. This is because, from Eq. (5), Op and Pp should satisfy...

Characteristic absorbance ratios have been shown useful for several other applications. For example, various heme structures can be distinguished by specific spectral elements in the Soret band (400-450 nm) region. Two separate groups of researchers have shown that Trp and Trp-related structures can also be differentiated by characteristic wavelength ratios at 255 and 270nm [17,18]. However, as pointed out by Rozing [19], these methods have serious limitations, particularly when more than one aromatic residue occurs in a peptide. 

Although the definition of shallow water can be signal dependent, in terms of depth-to-wavelength ratio, water depth of less than 100 m is generally referred to as shallow water. In shallow water, the SVP is irregular and difficult to predict because of large surface temperature and salinity variations, wind effects, and multiple reflections of sound from the ocean bottom.
