In figure 8(a) the top of the cap wasn t reconstructed well enough due to the same reasoning as in object no. 1. A similar deficiency is caused by a non sufficient number of exposure angles. Figure 8(b) shows the horizontal edge of the caps bottom. In Fig. 8(c) the side of the vial is clearly seen, yet with the reconstruction distortion pointed out for object 1. Figure 9... [Pg.482]

Figure Al.7.5(a) shows a larger scale schematic of the Si(lOO) surface if it were to be biilk-tenninated, while figure Al.7.5(b) shows the arrangement after the dimers have been fonned. The dashed boxes outline the two-dimensional surface unit cells. The reconstructed Si(lOO) surface has a unit cell that is two times larger than the bulk unit cell in one direction and the same in the other. Thus, it has a (2 x 1) synnnetry and the surface is labelled as Si(100)-(2 x i). Note that in actuality, however, any real Si(lOO) surface is composed of a mixture of (2 X 1) and (1 x 2) domains. This is because the dimer direction rotates by 90° at each step edge.

Small full-thickness wounds are closed and sealed off quickly by reconstruction of the epidermis from the edges of the wound. Large full-thickness injuries take too long to heal by this process and require grafting. All such wounds remain highly permeable until covered over again with a healthy, fully differentiated epidermis. [Pg.210]

After this reconstruction the scattering pattern should be smooth. If, on the other hand, seams are observed at the edges of the former invalid regions this shows that penumbra was not detected and the mask of the valid pixels was chosen too large. Solution erode the old mask and return to the start of pre-evaluation. [Pg.101]

Using the secret key, one reconstructs the binary string M, and the graph G with all the extra edges added as in the embedding process. [Pg.5]

A mechanism which proceeds through surface reconstruction of the substrate has been identified for Ni deposition on Au(lll) [120, 121]. The process begins with place exchange of nickel into a particular position in the reconstructed Au(lll) surface, followed by deposition of Ni islands on top of the imbedded atom. At higher overpotentials, nucleation occurs instead at step edges, so that control of the potential allows control of the nucleation process and the distribution of Ni in the early stages of growth. In this instance, the nucleation process has been captured by STM on the atomic scale. [Pg.179]

To overcome this limitation, a series of images of an entire field of cells can be obtained, then the waves can be visualized when the images are played back in rapid sequence. Specific lines of analysis can then be chosen after the experiment is completed. The line is selected to be perpendicular to the wave front (that is, along the direction of propagation). As before, the lines are stacked on top of one another, yielding a reconstructed line scan that contains all the information of a true line scan. The leading edge of the Ca2+ wave appears on the line scan as a sharp line with a constant slope. Since the slope is distance/time, appropriate conversion factors allow true speeds to be obtained in jUm/s. [Pg.177]

Addition of the first components up to p = 9 is shown in Figure 2.10. Reconstruction of the boxcar function is rapid although ears persist next to the edge, a feature characteristic of discontinuities and known as the Gibbs effect , o... [Pg.103]

Two basic issues can be distinguished here (i) the physico-chemical nature of zigzag and armchair sites at the edges of fused-benzene-ring structures, including their differences and similarities with respect to polycyclic aromatic hydrocarbon (PAH) molecules, and (ii) the reconstruction of these edges to potentially more stable structures. [Pg.505]
