A collaborative editing system defines operational transforms for transforming conflicting operations on styles of the text of the document. An embodiment of a method of the present invention may comprise introducing a treatment fluid comprising nano-clay into a subterranean formation. The selected middleware component is then dynamically assembled at the client. For each exposure, the mechanism sets the corresponding Fourier coefficients to zero for spatial frequency terms greater than the cut-off frequency of the optical system. The external element obtained is removed from the master mold.
