Binomial relation

Finally, this result can be given a more compact form, if the binomial relation is used to eliminate the -summation. The xc-contribution is extracted from via (2.3, 2.27, 2.35). Introducing the interaction operator... 

This resembles the binomial relation suggested by Coulomb and much favored by some workers. It has been used in many misleading connotations. In a detailed discussion of this it has been suggested (Tabor ) that if multinomial equations are to be favored in friction there are much better reasons for using a quinque-nomial (penta-nomial, 5-term) equation rather than a binomial. 

If the reaction is not too far from equilibrium such that S is small, the rate of reaction r can be expressed in S by substituting terms as [A]gq - aS for the concentrations in (2.2). Using the binomial relation... 

Stresses are usually related to strains through an effective modulus. If the components of stress are nondimensionalized by a suitable scalar modulus c, then they are also of order c. Using (A.94), (A.lOl), and the binomial theorem in (A.39), the relation between the normalized spatial stress s = s/c and the normalized referential stress S = S/c becomes... 

A related problem is to find the probability of M failures or less out of N components. This is found by summing equation 2.4-9 for values less than M as given by equation 2.4-10 which can be used to calculate a one-sided confidence bound over a binomial distribution (Abramowitz and Stegun, p. 960). 

A paper published by Hall and Selinger [3] points out that an empirical formula relating the concentration (c) to the coefficient of variation (CV) is also known as the precision (cr). They derive the origin of the trumpet curve using a binomial distribution explanation. Their final derived relationship becomes equation 72-2 ... 

There are a couple more entries for 5-MeO-DMT, one very important one, and the other quite trivial. There is a drug-use phenomenon that is often referred to by the popular title of "toadlicking." The toad involved is the Sonora Desert Toad, also called the Colorado River Toad, and carries the binomial Bufo alverius. It is not the closely related marine toad Bufo marinus, as... 

In practice, simpler though less reliable tests are used for evaluating the state of mixing. One of these involves calculating certain mixing indices that relate representative statistical parameters of the samples, such as the variance and mean, to the corresponding parameters of the binomial distribution. One such index is defined as follows ... 

Symmetrically shifted pulses have been proposed as a means of solvent suppression. Symmetrically shifted pulses are symmetrically shifted laminar pulses that contain equal numbers of rectangular pulse components of the same phase at an offset frequency. The basis of the symmetrically shifted pulse family is the SS pulse which is conceptually equivalent to applying simultaneous ir/2 rectangular pulses with two separate, but in-phase, transmitters at offset frequency from the water. On a practical basis an SS pulse is obtained by a complete Itt cosine modulation of a single transmitter (see Fig. 15). An S pulse is half of an SS pulse (i.e. a half-cycle tt pulse) which results in a narrower null and a 180° phase inversion at the transmitter frequency. They are also the soft, continuous equivalent of binomial sequences. The SS and S pulses have broader excitation maxima than the sinusoidal profile of the JR sequence. The method has maximal excitation at an offeet frequency of second-order U-shaped water suppression. The exdtation profile is related to the maximum amplitude modulation and can be determined by numerical evaluation of the Bloch equations. Hence a new pulse shape must be used for each excitation window. The SS pulses give better water suppression than the JR sequence, but at the expense of poorer excitation of resonances closer to the water. Also, there is no phase inversion at zero frequency. The S pulse gives better excitation near the water frequency but with less water suppression.
