A mathematical model of wheelchair racing
… toward improved performances. In this thesis, a mathematical model is developed, which is capable of providing such valuable kinematic and kinetic information. This two-dimensional model represents the body segments as a coupled pendulum system of point masses and the wheel as a distributed-mass …

Towards a mathematical model of tonality
… performance decisions. The proposed Spiral Array model offers a parsimonious description of the inter-relations among tonal elements, and suggests new ways to re-conceptualize and reorganize musical information. The Spiral Array generates representations for pitches, intervals, chords and keys …

A Mathematical Model of the Sleep-Wake Cycle
… use the S-system method for the development of a mathematical model consisting of two phases. The first phase covers the switch between wakefulness and sleep, which is controlled by the interactions between wake- and sleep-promoting neurons, whereas the second phase addresses the generation of …

A Mathematical Model for Type II Instrumental Discriminations
… assumptions found in the Trabasso & Bower (1968) mathematical model for type I and relevant redundant cue (RRC) discriminations, a mathematical model was proposed for type II discriminations. A type I discrimination has one relevant cue. An RRC discrimination has two relevant cues, either of which …

A mathematical model for managing equity-linked pensions
… [10] for pricing these minimum guarantees. The model they developed prices these minimum guarantees using option pricing theory. We also look at the model proposed by Deelstra et al. [13] which prices minimum guarantees in a stochastic financial setting. We conclude this mini-thesis with new …

A Mathematical Model To Simulate Small Boat Behaviour
The use of mathematical models and associated computer simulation is a well established technique for predicting the behaviour of large marine vessels. For a variety of reasons, mainly related to effects of scale, existing models are unable to adequately predict the manoeuvring characteristics of …

A mathematical model of a grazing system including beetles
[PAGES SCANNED INCORRECTLY] A number of mathematical studies of herbivore (predator)- grass (prey) models (e.g. Noy-Meir 1975,_ 1976,1978; Wielgolaski 1973; Christian et al. 1978) have been developed. With the exception of a few (Jackson 1980), in all these models the accumulation of dung in …

A Mathematical Model of Adhesion Interactions between Living Cells
This thesis presents a simple force-based model of moving and interacting cells that incorporates a realistic description of cell adhesion and applies it to a system of spherical cells. In addition, several results in matrix theory are proved with the end of showing that the equations produced by …

A mathematical model of coal-fired fluidised bed boilers
A mathematical model of a large coal-fired fluidized bed boiler for power generation is synthesised. The effect of variations in the main parameters of the model on variables such as the background carbon concentrations in the bed, and the transient response of heat evolution are studied. The …

A mathematical model of polymerase chain reaction induced stutter
… is achieved through data analysis, probabilistic modeling, and statistics. We find that a mathematical model that combines stochastic effects from PCR with fluorescent noise explains the most significant features of the observed phenomena.

A mathematical model of transient flow in pipeline filling
A mathematical model was developed for the rapid filling of an initially dry pipe. The pipe was assumed to be horizontal and to contain an orifice at the downstream end. The key elements of the model were the momentum equation governing the flow of the water, the thermodynamic equations for the …

Time-optimal CNC tool paths : a mathematical model of machining
Free-form surface machining is a fundamental but time-consuming process in modern manufacturing. The central question we ask in this thesis is how to reduce the time that it takes for a 5-axis CNC (Computer Numerical Control) milling machine to sweep an entire free-form surface in its finishing …

A mathematical model of iodine spiking in pressurized water reactors
… is termed "iodine spiking.” A physical model of this process is sought for explanatory and predictive purposes. A FORTRAN code is developed that solves a system of differential equations which describe the production and removal of iodine in the fuel, gap region, and primary coolant. As …

A mathematical model for the detection of deep space objects
… with certain probabilities was investigated. A mathematical model was then developed from given problem specifications that deals with the trade-off of various parameters involved in the detection problem. A software package that allows the user to input data interactively was written to …
