Computer generated map

The 2D autocovariance function was computed on the selected map region that contains the spot train (eight proteins) in addition to 53 proteins randomly located (4.5-7 p7 and 0.65-0.68 log Mr values, enlarged inset in Fig. 4.13a). From the 2D autocovariance function, the number of proteins present in this map region, m, can be correctly estimated m = 53 7 for the original computer-generated map containing 53 SCs (blue line in inset in Fig. 4.13b) and m = 62 8 for the map where the spot train was added (red line in inset in Fig. 4.13b).

Once the computer-generated map is available then the portion identifying solvent compositions which yield > 1.5 is clearly marked. Though a more exhaustive and objective approach than the MOM, the other disadvantages remain. 

CH3OH, has a polar covalent C-0 bond, and (b methyl-iithium, CH3Li, has a polar covalent C-Li bond. The computer-generated representations, called electrostatic potential maps, use color to show calculated charge distributions, ranging from red (electron-rich ... 

Figure 2.9.3 shows typical maps [31] recorded with proton spin density diffusometry in a model object fabricated based on a computer generated percolation cluster (for descriptions of the so-called percolation theory see Refs. [6, 32, 33]).The pore space model is a two-dimensional site percolation cluster sites on a square lattice were occupied with a probability p (also called porosity ). Neighboring occupied sites are thought to be connected by a pore. With increasing p, clusters of neighboring occupied sites, that is pore networks, begin to form. At a critical probability pc, the so-called percolation threshold, an infinite cluster appears. On a finite system, the infinite cluster connects opposite sides of the lattice, so that transport across the pore network becomes possible. For two-dimensional site percolation clusters on a square lattice, pc was numerically found to be 0.592746 [6].

The three dimensional structure was obtained by means of single crystal X-ray diffraction. CuKa radiation, a graphite monochromator, and a photomultiplier tube were used to collect 1825 total reflections on an automated diffractometer. Of these, 1162 were used for the analysis. Figure 2 shows a computer generated drawing of halcinonide. The position of the chlorine atom was not clear from the Patterson map, but the direct method program "MULTAN" gave its position. 

AIM theory provides a physical basis for the theory of Lewis electron pairs and the VSEPR model of molecular geometry. Equipped with computers and computer-generated, three-dimensional electron density maps, scientists are able to view molecules and predict molecular phenomena without even having to get off their chairs ...

Photoresists. These are used in holography because they can be employed to map holographic exposures into surface relief. This property is utilised in the production of embossing masters, reflection and transmission gratings and in computer generated holograms. 

These computer-generated electrostatic potential maps use color to show the calculated electron density in a molecule. Electron-rich regions are red and electron-poor regions are blue. 

In particular, the two tt bonding electrons are equally distributed among the [three OC sectors. Figure 9.6 shows a computer-generated relief map of the jelectron density of CO taken from ref. 119.
