It even seems possible that it has been a growing problem for pollsters: As Democrats have become increasingly dependent on irregular voters, it becomes more important for polls to accurately model the composition of the electorate.
According to the preliminary results of the ASPEN HYSYS conceptual process simulation model; the composition of hydrogen rich gas (0.62% H2O, 38.83% H2, 1.65% CO, 26.13% CO2, 0.08% CH4, and 32.69% N2) has been determined.
Thus, by weighting both groups with their inverse probability of treatment in the outcome model, the composition of the sample which has received treatment t is re-balanced.
Within the structural equations model the latent variable is represented by a reflective construct; one or more formative constructs model the composition of the variable [44].
In their model, the composition of the different layers would be the same but the first layer will incorporate the "impurities" randomly, whereas in subsequent layers it will be directed by the substrate.
We try to relate the solid composition of the (Ba,Sr SO4 solid-solution to the conditions at the geothermal plant concerning temperature, pressure, and solution composition, and discuss it with respect to the challenges in modelling the composition of (Ba,Sr SO4 solid-solutions on the basis of thermodynamic mixing models.
In order to achieve this, we carefully considered three aspects of our model: the composition of the groups, the nature of group activities, and accountability in evaluation.
To model the composition of nucleotide pairs which are argued to have an important effect on formation of secondary structures, a model that preserves both the amino acids order and content, and the frequencies distribution of 16 possible pairs of adjacent nucleotides (dinucleotides) for each sequence separately was used.
And these two known as HD 209458b and HD 189733b had a signature for water that was much fainter than astronomers had been expecting from planet models and the composition of their stars.
And this eventually led to a successful theoretical model of the composition of hadrons, namely quantum chromodynamics, or the quark-model of strong interactions.
