A mathematical model of the “Rattleback”
International Journal of Non-Linear Mechanics, 1980Abstract A mathematical model is presented which gives a fairly comprehensive explanation of the strange behavior of a certain type of stone, called a Celt or Rattleback, which if placed on a flat horizontal surface and caused to spin in a particular direction about a vertical axis, will quickly stop spinning, oscillate about a horizontal axis, and ...

A mathematical model for spirometry
Computers and Biomedical Research, 1987A model originally designed to fit population growth data was investigated to determine whether it could fit spirometric traces as a function of time in normal and ill humans and in normal rats, obtained, respectively, by spirometer and whole-body plethysmography.

On mathematical modeling in robotics
1993Some selected applications of mathematical modeling methods in the AI field robotics are presented in survey style by examples of geometric reasoning, topological reasoning and so-called fibered logical spaces for logical reasoning in robotics. The main perspective is on interaction and combination of different fields and methods from symbolic ...

Models for mathematical systems
Communications of the ACM, 1966A program, written for the IBM 7090, which defines a model for a finite collection of associative algebras for the computer, is described and illustrated. The program contains a structure broad enough in scope to allow one to perform operations on such diverse mathematical concepts as differential equations, infinite series and differential forms in a ...

Mathematical Modelling of the Internet
2000Abstract In the current Internet, the rate at which a source sends packets is controlled by TCP, the transmission control protocol of the Internet [8], implemented as software on the computers that arc the source and destination of the data. The general approach is as follows. When a resource within the network becomes overloaded, one

Mathematical Models for Rabies
2011Rabies virus and its associated host-pathogen population dynamics have proven a remarkable model system for developing mathematical models of infectious disease emergence and spread. Beginning with simple susceptible-infectious-removed (SIR) compartment models of fox rabies emergence and spread across Western Europe, mathematical models have now been ...

The Mathematics behind Modeling
1998The purpose of this chapter has been to furnish insight into the theoretical background on which compartmental modeling software packages are based. To accomplish this goal, only the basic ideas were stressed, avoiding discussion of the intricacies required for efficiency.
