Fig. 9.4 The calculated TM and TE modes for X 1550 nm light propagating in the 220 nm x 450 nm photonic wire waveguide shown in Fig.9.3. The mode electric field profiles are shown as line plots along the center axis of the waveguide (indicated by the dashed lines), as well as in full cross section by gray scale contour plots...

Figure 17.6 shows the results for a typical composite image of the entire flame in which the image intensity, or gray scale value, is plotted on the vertical axis against radial and axial distance coordinates. To find the flame area, a threshold intensity is first picked and a binary image is created with all pixels with intensities above the threshold set to 1 (white) and the rest set to 0 (black). The number of white pixels is then proportional to the surface area of the flame at that intensity contour. This process is then repeated to build up a plot of flame area versus a normalized threshold number (intensity value/256) such as that shown in Fig. 17.7a. 

Fig. 8.10. Spectrograms of the atomic dipole (logarithmic scale, white gray = 1 0) and harmonic held (contour plot, logarithmic scale 1 10) at r = 0 and z = 9mm, as generated by the PC (a) and NC (b) pulses...

Figure 4 Plot of 2o- error in age versus age, both on log scales. Pa dates are illustrated with solid circles °Th dates are illustrated with gray squares. Contours indicate analytical error in Pa/ su ratio and pertain only to the solid circles. All data were collected using mass spectrometric techniques, and illustrate the high precision of this technique despite extremely low natural concentrations of the isotopes of interest (after Edwards et al., 1997).

Fig. 147. Time evolution of (i) transmittance (at 1.96 eV) (dashed line) and resistivity (soUd Une) (ii) Contour plots of the X-ray intensity as a function of time for 13 x (6 nm Mg -I- 6 nm Y) multilayer capped with Pd (10 nm). At t = 0.18 h hydrogen was introduced into the system. The gray scale correspond to a logarithmic intensity scale...
