Relations between Generations

Several parameters come into the relation between density and equivalence ratio. Generally, the variations act in the following sense a too-dense motor fuel results in too lean a mixture causing a potential unstable operation a motor fuel that is too light causes a rich mixture that generates greater pollution from unburned material. These problems are usually minimized by the widespread use of closed loop fuel-air ratio control systems installed on new vehicles with catalytic converters. [Pg.188]

In a real rotor system the amount and location of unbalances cannot always be found. The only way to detect them is with the study of rotor vibration. Through careful operation, the amount and the phase angle of vibration amplitude can be precisely recorded by electronic equipment. The relation between vibration amplitude and its generating force for an uncoupled mass station is... [Pg.585]

Previously Wright had studied asymptotic relations between the coefficients in two generating functions related by the formula equation... [Pg.133]

Storer model used in this theory enables us to describe classically the spectral collapse of the Q-branch for any strength of collisions. The theory generates the canonical relation between the width of the Raman spectrum and the rate of rotational relaxation measured by NMR or acoustic methods. At medium pressures the impact theory overlaps with the non-model perturbation theory which extends the relation to the region where the binary approximation is invalid. The employment of this relation has become a routine procedure which puts in order numerous experimental data from different methods. At low densities it permits us to estimate, roughly, the strength of collisions. [Pg.7]

The overall strategy for finding the relation between K and Kc is to replace the partial pressures that appear in K by the molar concentrations and thereby generate Kc. For this calculation, we write activities as Pj/P° and [J]/c° and track the units by keeping P° and c° in our expressions. [Pg.491]

However, a preference relation between such schemes is some consensus of opinion. The reader can encounter in the theory and practice various schemes generating approximations of order 2 in time and space ... [Pg.522]

In Chapter 5.2, S. Candel, D. Durox, and T. Schuller consider certain aspects of perturbed flame dynamics. The relation between combustion instability and noise generation is described by reference to systematic experiments. The data indicate that acoustic emission is determined by flame dynamics. On this basis, combustion noise can be linked with combustion instability. [Pg.229]

Of course, care should be taken when comparing the experimental data and the modeling results the model is an approximation, and the experiment has its uncertainties. The most important approximation is that the model is one-dimensional. A main uncertainty of the experiment is the relation between source power and plasma power (see Section 1.3.2.3). The source power is defined as the power delivered by the power generator. In experiments, the source power is a discharge setting (Table IV). The plasma power is the power dissipated by the plasma. As a rule, this plasma power is smaller than the source power, due to losses in the matching network, which matches the plasma impedance to the impedance of the source power generator, viz., 50 [180]. From comparison of experimental data... [Pg.53]

Equations 12.6.2 to 12.6.4 and the relation between s, y, and are sufficient to calculate the global rate at specified values of TB and CB. Unfortunately, information on the last relation is rather limited. The curves presented in Figure 12.10 and reference 61 give the desired relation for first-order kinetics, but numerical solutions for other reaction orders are not available to this extent we will presume that numerical solutions may be generated if needed for design purposes. [Pg.490]

In 1775 Lavoisier discovered oxygen and the relation between air and life. This renewed the controversy about spontaneous generation, the objection to Spallanzani s results being that it was the exclusion of air (oxygen) from the flasks which prevented the development of life. [Pg.45]

Note also that one can always generalize the above approach so that the same random output does not occur twice anymore, but rather occurs as related, for example. This new relation (instead of the previous equality relation) is needed to ensure that the output of the modified circuit stay unaltered. However, we believe that all such approaches to fix the above schemes will eventually be broken because it is quite hard to hide the relation between the two runs of the pseudo random generator. Therefore it will be a non trivial task to fix these schemes. [Pg.13]
