The surface wave propagation is computed by the phase-resolving non-hydrostatic SWASH code. The SWASH data are used to make a suitable dynamic boundary condition at the beach face to force Richards' equation. The latter is solved by …

WebGolay defined his “complementary series”, which we call sequences, in his 1961 paper ([2]) in three equivalent ways. A proof of equivalence will follow the definitions. For the first definition, we need the notion of a separa-tion of a sequence.

WebThe Golay equation on the right is the basic equation describing the dispersion that takes place in an open tubular column. It is the van Deemter equation minus the A-term, which doesn’t apply to open tubes. (This is the main reason why capillary GC is so much more efficient than packed GC and
WebIn 1964, Savitsky and Golay proposed a method equivalent to LOESS, which is commonly referred to as Savitzky–Golay filter . William S. Cleveland rediscovered the method in 1979 and gave it a distinct name. The method was further developed by Cleveland and Susan J. Devlin (1988). LOWESS is also known as locally weighted polynomial regression. WebThe Golay equation can also be used to examine the dispersion that takes place in connecting tubes, detector cells and other sources of extra-column dispersion. Extra-column dispersion will be considered in another chapter but the use of the Golay equation for this purpose will be briefly considered here.
WebOne can calculate the resolution of a chromatographic system from two consecutive peaks using the following equation: (Equation 8-8)R = 2⋅dW1 + W2 where d is the separation between two peaks (measured from top to top) and W1and W2are the widths at baseline of the two peaks. This is illustrated in Figure 8-5.
