Using Integers

The problem with this approach is that since it is impractical to list all possible values an integer can take, to avoid latches either the default case branch must be specified or the full case synthesis directive must be used. Another problem with this approach is not good readability.

An eigencomponent routine confirms that the matrix ATA has one eigenvalue equal to zero with corresponding eigenvector [0.485, —0.485, +0.2425, —0.485, -0.485]1. It is common practice to use integers as stoichiometric coefficients. This can be achieved by dividing each component by the component of smallest modulus (0.2425), which produces the vector [2, - 2,1, - 2, - 2] corresponding to the mineral reaction... 

The focus on the start-up phase of a hydrogen infrastructure, by taking into account uncertainties of future market development over the step-by-step optimisation (myopic approach) and the influence of single production plants (using integer variables), thus allowing economies of scale to play out. 

In a methodology they developed called holographic QSAR (44), Hurst and Patterson have used integer-valued vectors to characterize the frequency of occurrence of molecular fragments. However, they do not use the vectors in their native form but rather fold them into a smaller vector by hashing. 

Schneider et al. (45) have also used integer-valued vectors to characterize what they call 2-D pharmacophores. 

This function closely fits the standard gamma function of gamma(x) =xZ3. The two sections (one linear and the other nonlinear) were introduced to allow for invertability using integer arithmetic. Finally the gamma-corrected RGB values are mapped to the range [0, 255].

The term in Eq. (6.167) can be rewritten in closed form using integer moments of up to third order. On the other hand, the right-hand side of Eq. (6.168) cannot be written in terms of any finite set of integer moments and must therefore be closed (e.g. using quadrature). The collision source term C2oo,i2 has four contributions ... 

Aware of only these four hues, Balmer calculated 1 for a fifth hue lyn = 7). A hue with a wavelength very close to the predicted value was observed experimentally. Balmer suggested that his formula might also predict wavelengths of other series of spectral fines by using integer values for n other than 2 and rw n L 1. Other series of hydrogen lines were not known then, but were subsequently discovered (the Lyman, Paschen, Brackett, and Pfund series of fines). 

Discrete observations. Values which arise from counting events and (usually) which can be represented using integer values. An example would be the number of seizures suffered in a given time interval by epileptic patients.

The method of writing the equations is very cumbersome as well as the presentation of the numerical model [41]. Surely, a more simple way is based on using integers i and j, so that the following is obtained for the position of the very thin sheet in which the concentration is constant x = i. Ax, and for the time t = j. At. By using these symbols, the concentration is written as C j.

In the examples of nuclear reactions which follow we will focus on conservation of particles even though we know from Einstein s formula E = mc that small amounts of mass can be converted into enormous amounts of energy and we will use integers for particle numbers. In this way, we have to balance the isotope superscripts as well as the subscripts. Note in the fission of U, the number of (protons + neutrons) in the superscript adds up to 236 on both sides of the reaction and the number of protons in the subscripts adds up to 92 on both sides of the reaction. Here are a few nuclear reactions given in the Sasin and Sasin text [10,11] (by peimission) ...
