Pluralization: A Mathematical Model

Operations Research, 1972
This is the first of a series of simple mathematical models to explore the concept of decentralization. The primary focus is on pluralization as one of three aspects of decentralization. We derive expressions for cost and for net benefit as a function of the number of identical, uniformly dispersed facilities capable of servicing requests from sources

Models and Mathematics

JAMA, 1965
Scientific investigation is a particular search for a comprehensive view of nature; it is, in effect, a matter of proposing questions concerning phenomena and then searching for the answers in a systematic manner. An important aspect of this investigation, therefore, is the separation of the currently answerable from the unanswerable questions.

Mathematical Models of Running

SIAM Review, 1993
Based on a careful appraisal of the various models, it is suggested that approximately \(3\%\) of a sprinter's effort is spent on overcoming air resistance, a figure that is supported by an independent estimate derived from the long jump. An interesting consequence of the analysis is the feature that the benefits of sprinting at altitude cannot be ...

Mathematical Modeling in Chronobiology

2013
Circadian clocks are autonomous oscillators entrained by external Zeitgebers such as light-dark and temperature cycles. On the cellular level, rhythms are generated by negative transcriptional feedback loops. In mammals, the suprachiasmatic nucleus (SCN) in the anterior part of the hypothalamus plays the role of the central circadian pacemaker ...

Mathematical Modelling in Dutch Textbooks: Is It Genuine Mathematical Modelling?

2017
n this chapter, we analyse the two most frequently used Dutch mathematics textbooks for upper secondary schools in order to determine to what extent the tasks in these textbooks meet the criteria we have set for genuine mathematical modelling: does a modelling task have a modelling purpose, and do the students have to perform characteristic modelling ...

Mathematical modeling of bioassays

Biochemistry (Moscow), 2017
The high affinity and specificity of biological receptors determine the demand for and the intensive development of analytical systems based on use of these receptors. Therefore, theoretical concepts of the mechanisms of these systems, quantitative parameters of their reactions, and relationships between their characteristics and ligand-receptor ...

Mathematical Models of Hysteresis

Physical Review Letters, 1986
A new approach to Preisach's hysteresis model, which emphasizes its phenomenological nature and mathematical generality, is briefly described. Then the theorem which gives the necessary and sufficient conditions for the representation of actual hysteresis nonlinearities by Preisach's model is proven.

Mathematical Models in Marketing

Operations Research, 1967
For a marketing situation, mathematical models are developed expressing the relation between net revenue and the variables that affect it. These models are extensions of the ones discussed by Mills, and Krishnan and Gupta. Mills assumed that each competitor has only one controllable variable, viz., promotional effort.
