Geometrical deformations

It performs information embedding in the spatial domain and hence is sensitivity to geometric deformation such as image miss-alignment and to the presence of stains or scribbles on the printed media. 

The dispersion in geometrically deformed tubes (squeezed, twisted and coiled ) has been extensively studied by Halasz (6, 7 and 8), and the effect of radial convection (secondary flow) on the dispersion introduced in tightly...

Geometrical deformations in adduct of 2-nitroimidazole with sodium derivatives of crown ether (15-crown-5)-(2-nitroimidazolato)-sodium are observed [48],... 

Do all vital processes involve pulsating structures undergoing simultaneous cycles of geometrical deformation and electro-magnetic polarization If so do mutated genotypes have to be capable of conforming to such pulsations ...

The ideas introduced in this section provide a skeletal description of some of the ways in which the geometric deformations in solids are considered. To provide a more concrete realization of these ideas, we now introduce several case studies... 

The geometric deformation of molecules can also induce orbital distortions. Seebach and coworkers [IS] have shown that dioxanones 1 are distorted. In the ground state, carbon-4 is pyramidalized through the mean plane of the ring toward carbon-2. This distortion is enhanced in the transition state for a nucleophilic attack, so such reactions are stereoselective because of better overlap control (Figure L7). 

Table 7.15 displays NBOs and occupancies of the n%-and Uq -radical species at the torsional crossing. Despite strong geometric deformation and electronic excitation, the resemblance of these NBOs to one another as well as to those of lower-lying species is quite apparent. Thus, one can conclude that a compact set of NBOs (or their NHO hybrid constituents) provide a useful basis set for concise, acciuate, and descriptive valence-shell configurational assignments over...
