Mathematical Modelling and Mathematical Methods in Energy
Numerical Linear Algebra with Applications, 2006The workshop on Mathematical Modelling and Mathematical Methods in Energy was held in COPEL Building, Curitiba, Brazil from 29 November to 1 December 2004 with more than 100 participants. The scientific programme consisted of 20 invited talks and 20 contributed papers. All talks were well attended with deep discussions.

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, 1993Based 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
2013Circadian 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?
2017n 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), 2017The 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, 1986A 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, 1967For 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.

Modelling with Mathematics and Technologies
2012This chapter seeks to provide an integrating theoretical framework for understanding the somewhat disparate and disconnected literatures on “modelling” and “technology” in mathematics education research. From a cultural–historical activity theory, neo-Vygtoskian perspective, mathematical modelling must be seen as embedded within an indivisible, molar ...

Information Processing & Management, 1984
Abstract An object of serious study in the information sciences is printed language, called text. This paper presents numerous examples of mathematical models of text and in so doing exposes some interesting results and problems associated with the linguistic, mathematical, and computational aspects of current research involving text.
