We deal with the lumpability approach to cope with the state space explosion problem inherent to the computation of the performance indices of large stochastic models using a state aggregation technique. The lumpability method applies to Markov chains exhibiting some structural regularity and allows one to efficiently compute the exact values of the ...

Proportion: Learning Proportional Reasoning Together
2012Proportional reasoning is a broadly applicable skill that is fundamental to mathematical understanding. While the cognitive development of proportional reasoning is well understood, traditional learning methods are often ineffective. They provide neither real-time feedback nor sophisticated tools to scaffold learning.

Journal of Philosophical Logic, 1995
The author's aim is to defend the Aristotelian concept of distribution against Geach's criticism (see section IV) by applying it to extended syllogistic systems. Section I deals with ``fractional'' syllogistics containing statements of the form ``more than 1/2 of the \(S\) are \(P\)'' or ``at least 7/8 of \(S\) are not \(P\)''.

Knowledge of the body proportions of the growing child is essential since the individual parts of the human body develop at different speeds which results in a constantly changing pattern of the interrelationship between the various measurements. At any age a child can be recognized by its proportions characteristic for that age.

On proportional plus proportional-integral suboptimal control
IEEE Transactions on Automatic Control, 1975Two suboptimal control policies employing integral state feedback suitable for nonlinear systems and nonquadratic performance functionals have been proposed. Necessary conditions are obtained using the variational approach to select optimally the time-invariant parameters for a general control structure of which the two suboptimal policies proposed are

How proportional is proportional representation?
The Mathematical Intelligencer, 1986In a very popular way the author discusses the problem of division of seats in some assembly between parties provided the number of votes received by these parties at the elections is known. The author shows why the proportional distribution is not adequate and discusses different quota methods, e.g. D'Hondt's rule, Droop quota etc.

Proportional Budgeting and Decentralization
Econometrica, 1995Summary: Governments, universities, and other not-for-profit organizations frequently employ two -- potentially incongruent -- budgeting procedures: proportional budgeting and decentralization. The former entails allocating budget increments or decrements uniformly across divisions or sectors of the organization.

Confidence Intervals for Proportions and Differences in Proportions
2014Proportions, fractions, percentages, risks, hazards are all synonymous terms to indicate what part of a population had events like death, illness, complications etc. Instead of p-values, confidence intervals are often calculated. If you obtained many samples from the same population, 95 % of them would have their mean results between the 95 ...
