Inequality issues

Some of the basic mathematical requisites for scientific programming include understanding of (a) rules of operator precedence, (b) machine precision, (c) equality and inequality issues, and (d) potential for overflow/underflow of numbers. Related concepts such as relative and absolute differences are also important for scientific programming. [Pg.36]

Since international justice requires developed nations to help reduce global health inequalities, and one of the best ways of reducing health inequalities is to promote access to medications for developing nations, it follows that international justice requires developed nations to help developing nations attain access to medications, especially those used to treat or prevent infectious diseases. There are two different access issues that need to be addressed availability and cost. [Pg.93]

The simple inequality (4.10) captures the essence of the second law. Its general consistency with universal inductive experience will be established in Section 4.4, and its further consequences (culminating in the final form of the second law as expressed by Clausius) will be developed in Sections 4.5-4.7. Thus, Carnot s remarkable principle provides virtually complete answers to the questions posed at the beginning of this chapter, although the relationship of (4.10) to these broader issues will certainly not become obvious until the following section. [Pg.126]

There are two issues central to this proposal, namely is there an inversion of phase stability at atmospheric pressure and does the hexagonal phase then crystallize before the orthorhombic As will become clear, the available data do not allow a definite answer to the first but probably not, to the second the answer is certainly no. We consider these matters in turn, first testing the inequality 5 against measured parameters. [Pg.10]

The symbol ([A,B]) is just (T [A,B] T, a quantum-mechanical average over the quantum state Tq. The inequality is known as Heisenberg-Kennard-Robertson relationship, which has often been interpreted as the mathematical expression of the disturbance following measurement. Ballentine noted that this relationship does not seem to have any bearing on the issue of joint measurement instead, this relation can be traced back to the preparation process of an initial state, see Ref. [1,10]. [Pg.58]

To show inequality (114), the preceding assumptions (i) through (vii) were made. When assumptions (i), (iv), and (v) are not satisfied, robustness issues arise, because the process behaves differently from the assumptions of the controller. When assumption (vi) is not satisfied, then fragility issues arise, because the controller behaves differently from the way it was designed. It should be mentioned that the issue of fragility is not confined to constrained MFC systems. Keel and Bhattacharyya (1997) showed that even in linear time-invariant control systems, there are controllers for which extremely small deviations of the controller parameter values from their designed values can result in instability (see Section IV,F). [Pg.176]

Irrespective of the type of analysis, monitoring and evaluation of equity must compare differences in outcomes by socioeconomic status. Without a consistent summary measure, confusion can arise, because differences or changes over time can be caused by either variation in the socioeconomic status of the populations being compared or by variation in the distribution of health outcomes among them. This issue can be addressed by using appropriate summary measures, such as concentration coefficients or the index of relative inequality (Wagstaff, Pad, and Van Doorslaer 1991). [Pg.99]

Fractal Model. We consider in more detail the issue of relaxation times relevant to our fractal model of anomalous relaxation. As appears from the potential energy landscape for a system under the action of an external electrical field (Fig. 67), the energy differences between minima separated by energy maxima of different levels of self-similarity diminish, the larger the number of a selfsimilarity level. In view of the standard definition of a relaxation time, x eu "r. one may write the following chain of inequalities,... [Pg.246]

As previously noted, if responses are observed in real time, steady states can be observed and temporal inequality ceases to be an issue. However, this can be an issue in stop-time experiments, where real-time observation is not possible and the product of a drug response interaction is measured at a given time point. This is further discussed later in the chapter. [Pg.89]

These issues arise due to the limitations imposed by machine precision. Very often, two quantities that should be identical will not pass the equality test because of the different ways in which they are computed. Sometime inequalities are also impacted. As an example, the Matlab statements in Code Block 2 (Figure 2.2) will produce unexpected errors (the statements were tested on Matlab Version 7.01 interactive default setting of single precision). [Pg.37]

When Statements 1 and 2 are used to calculate the values of two small numbers, x and y , one of them ( y ) is incorrectly rounded off to zero, whereas the smaller of the two ( x ) still retains nonzero value. Thereafter, all subsequent comparisons of x and y lead to unexpected and incorrect results. For example, the results of comparison in Statements 4 and 5 are definitely wrong, whereas the comparison in Statement 3 may or may not lead to an incorrect conclusion. There are some techniques to overcome these issues. For example, Matlab provides a variable eps that indicates the smallest floating point increment possible in a given precision. Statements 9 and 10 use eps in the context of comparing the difference of two numbers, as well as in deciding whether inequality comparisons can be made, and produce more predictable results. [Pg.37]

Racial inequality remains one of the most controversial and emotional issues in American life. The euphemistic word diversity is used as shorthand whenever speakers are referring to the issue of inequality among... [Pg.197]

In many applications satisfying the inequality, m > n, can represent a serious problem as ILS requires more standard calibration mixtures than the number of wavelengths (independent variables) selected. This can serve to limit the spectral reange or resolution of the data used in the analysis. Wavelength, variable, selection is an important issue. [Pg.181]
