Maximum rankings, comparison

Test can be made at a number of extensions and compounds can be compared in terms of fatigue life at the same strain or at the same strain energy. In the latter case, absolute comparisons can be made on compounds of different modulus. When comparing different rubbers, it is necessary to test at a number of strains or to define the severity of conditions which will occur in service, because with the number of variables (G, K, W, n and C0) the ranking order may vary with the maximum strain employed. 

Note Species name, phylum or division, common name, and concentration of total MAAs ([MAA], in nmol mg-1 protein) are indicated. Notes describe whether samples are from a whole organism or specific tissues, and value indicates if data are from a single measurement, a maximum value from several samples (max), or a maximum mean value (mean) reported. See text Section II.A.6 for an explanation of how rankings were determined. The comparison of values from different research laboratories may be somewhat problematic as there are currently no commercial standards available for MAAs and calibration of instruments is achieved by a variety of means. 

The sweetness inhibitory activity of plant terpenoids is evaluated by placing 5 mL of 0.5 or 1 mM solution of the compound in the mouth for 2-3 minutes. On expectorating, the mouth is then washed with distilled water. Then, different concentrations of sucrose (0.1-1 mM) are tasted. The maximum concentration of sucrose at which complete supression of sweetness is perceived may then be recorded for each tastant [133]. In practice, antisweet compounds of plant origin have tended to be ranked in terms of sweetness inhibitory potency by comparison with gymnemic acid I (90) [19]. 

A company typically has several projects competing for funds to be invested. The projects are ranked based on their NPV and risk. This is an economic decision problem. However, each project is an optimization problem by itself For a valid comparison among projects, the optimum design is required for each project to have the maximum NPV. 

With 15 comparisons involving six pairs of S s and nine pairs of D s unweathered oils, the maximum [/-value would be 54 the value for random ranking would be 27. The better pattern recognition schemes gave values of 0-5 that is, the lower the number generated, the better the method was in making oil comparisons. (Note The random chance of getting a numerical value of less than 6 is 0.4%.)... 

A ranking system that is at least semiquaiMitative has been devdoped (Ref 26). In this syston, the value of a normalized erosion resistance, defined as the maximum rate of volume loss of a reference matoial divided by the maximum rate of volume loss for the material being evaluated, is computed. This allows comparison of materials that have been tested under different sets of conditions, provided that the refoence material has been tested under each the diffoent sets of conditions. Figure 8 is a summary of ntxmal-ized erosion resistance for a wide variety of alloys tested at different conditions, using 18Cr-8Ni austenitic stainless steel with a hardness of 170 HV as the...
