In addition, the geometry of the duct and trapping layers and the strength of the duct, often defined as the M difference of the trapping layer, are critical properties of a duct that regulate the impact of the duct on EM propagation. These properties of the duct, together with the M profile itself, determine the effects of the duct on the EM waves going through the medium.
The simulation result of wave trajectory path propagation in the coast of Lhoknga can be seen in Figures 6 and 7.
Then according to the characteristics of the stage the propagation period can be divided into different steps.
Figure 4 presents the guided light propagation by applying fixed voltage [V.sub.app] (1) = 2.2 V in channel 1 and applying voltage [V.sub.app] (2) = 0 V, 1.5 V, 2.2 V, and 2.8 V in channel 2, which correspond to Figures 4(a)-4(d), respectively.
The Influence of Fillings, Angle, and Distance on Crack Propagation. The mechanical properties of the fillings affect the discontinuity degree of the specimen, which was measured by the wave impedance.
In fact, as a more advanced modeling approach, the DEM has already been applied in some propagation software programs.
Therefore, the hydrostatic pressure needs to be updated with the propagation of the crack in real time.
(iii) Construction of propagation flow graph: we propose the construction method of taint propagation flow graph to backtrack taint source, which can precisely locate the specific offset of taint data.
Figure 4 presents typical combustion images obtained experimentally and an outline of the method used for analyzing the autoignition propagation speed.
In addition to propagation mechanisms, the network structure is also very important for the process of information propagation.
In Section 3, the investigative study results for the radiated electromagnetic noise propagation in the automobile test system is discussed.
Although vegetative propagation is an alternative way for the production of desired clones, propagation through traditional root cutting is not effective due to long procedure and slow growth (Tyagi and Prakash, 2004; Singh et al., 2008).
