A Mathematical Type for Physical Variables [PDF]

, 2008
In identifying the requirements of a markup language for describing the mathematical semantics of physics-based models, we pose the question: "Is there a mathematical type for physical variables?" While this question has no a priori answer, since physics is fundamentally empirical, it appears that a large body of physics may be described with a single ...

ON VARIABLES IN MATHEMATICS AND IN NATURAL SCIENCE

The British Journal for the Philosophy of Science, 1954
IN the development of mathematics and natural science which began in the seventeenth century, perhaps the most characteristic concept is that of a variable. But what is a variable ? Russell, who investigated all aspects of this notion, called it 'certainly ...

Affective Variables and Mathematics Education

The Elementary School Journal, 1984
to general feelings such as liking/disliking of mathematics, nor is it meant to exclude perceptions of the difficulty, usefulness, and appropriateness of mathematics as a school subject. There are several ways affective variables are related to mathematics learning. It is likely that a student who feels very positive about mathematics will achieve at a

GIRLS AND MATHEMATICS: PARENTAL VARIABLES

British Journal of Educational Psychology, 1979
Summary. 234 girls taking A‐level mathematics were compared with 265 girls taking A‐level French. They were more reserved (A), stable (C), tough‐minded (I), radical (Q1) and group‐dependent (Q2) on the 16PF, and less feminine on the CPI Fe Scale. Girls in both subjects tended to identify with their fathers rather than mothers. Father identification is

Complex Variables in Industrial Mathematics

1988
Complex analysis has long been regarded both as an elegant subject in its own right, and as a powerful tool in applied mathematics. The subject has inescapable limitations, however, and it might be said that it has been superseded by more modern methods.

Simulation of fetal heart rate variability with a mathematical model

Medical Engineering & Physics, 2017
In the clinic, the cardiotocogram (CTG), the combined registration of fetal heart rate (FHR) and uterine contractions, is used to predict fetal well-being. Amongst others, fetal heart rate variability (FHRV) is an important indicator of fetal distress.

Inequalities and mathematical properties of uncertain variables

Fuzzy Optimization and Decision Making, 2011
Uncertain variables are measurable functions from uncertainty spaces to the set of real numbers. In this paper, some important inequalities of uncertain variables, for example, extension of Jensen's inequality, Liapounov's inequality, and refined Markov inequalities are presented.
