Filter sequence

Figure 6b shows the unsheared 3Q MAS NMR spectrum of zeolite scolecite (which contains two non-equivalent four-coordinated Al sites) acquired with the three-pulse z-filter sequence. 

MQMAS/HETCOR experiments involving spin-5/2 nuclei have been reported by Chan [93] and more recently by Mali et al. [94] who obtained, respectively, an Al —MQHETCOR spectrum of magnesium aluminoborate and Al—> P MQHETCOR spectra of aluminophosphate molecular sieves. The authors of both reports used the z-filter sequence to convert both triple-quan-...

Subspace modeling can be cast as a reduced rank regression (RRR) of collections of future outputs on past inputs and outputs after removing the effects of future inputs. CVA performs this regression. In the case of a linear system, an approximate Kalman filter sequence is recovered from this regression. The state-space coefficient matrices are recovered from the state sequence. The nonlinear approach extends this regression to allow for possible nonlinear transformations of the past inputs and outputs, and future inputs and outputs before RRR is performed. The model structure consists of two sub models. The first model is a multivariable dynamic model for a set of latent variables, the second relates these latent variables to outputs. The latent variables are linear combinations of nonlinear transformations of past inputs and outputs. These nonlinear transformations or functions are... 

Probably require less postexchange processing than their aqueous exchange counterparts. As a minimum, the materials prepared by aqueous exchange must be filtered, then dried. They may further require one or more washing and filtering sequences, thus generating more wastewater... 

Some of these conditions can be weakened. ) The indicator function 1[o,d solves equation (10) with ho = hy = I and /i = 0 for all ft 0, 1. This is the simplest possible filter sequence. A fancier example is listed in Table 1, with its corresponding solution V to equation (10) plotted in Figure 7.
