#### Geogebra, tool for mediating knowledge in the teaching and learning of transformation of functions in mathematics.

(2011)

As a teacher of mathematics, I always taught the topic functions (graphs such as linear,
quadratic, hyperbola, exponential, trigonometric functions) in the same way all of my
twenty-three years in the profession. I often ...

#### Mathematics for future engineers : a study of teaching and learning mathematics in an engineering curriculum.

(2016-01-19)

This is a study of teaching and learning in the first mathematics module for engineering
students at a South African university. The theoretical framing of the study is derived from
multiple analytical tools: Bernstein’s ...

#### Chebyshev spectral pertutrbation based method for solving nonlinear fluid flow problems.

(2015-03-03)

In this dissertation, a modi cation of the classical perturbation techniques for solving nonlinear ordinary
di erential equation (ODEs) and nonlinear partial di erential equations (PDEs) is presented.
The method, called ...

#### Representation of regular formal languages.

(2014-05-17)

This dissertation presents three different approaches to representing Regular Formal languages, i.e., regular expressions, finite acceptors and regular grammars. We define how each method is used to represent the language, ...

#### Congestion control based on dynamics pricing scheme and service class-based joint call admission control in heterogeneous wireless networks.

(2015-02-26)

Next Generation of Wireless Networks (NGWNs) are heterogeneous and consist of several Radio
Access Technologies (RATs) that coexist in the same geographical area. This heterogeneity of
wireless networks is supposed to ...

#### Modeling the burden of disease for cattle.

(2014)

Summary measures of human population health (SMPH) represents approaches to
measuring the burden of disease. These approaches are divided into two classes: health
expectancies and health gaps. A health gap model approach ...

#### Spanning trees : eigenvalues, special numbers, and the tree-cover ratios, asymptotes and areas of graphs.

(2014)

This dissertation deals with spanning trees associated with graphs. The number
of spanning trees of a graph can be found by considering the eigenvalues of the
Laplacian matrix associated with that graph. Special classes ...

#### Analysis of co-infection of human immunodeficiency virus with human papillomavirus.

(2014-05-17)

We formulate a deterministic mathematical model for the co-infection of HPV with HIV without
treatment. Mathematical techniques were used to analyze the stability of the models in terms of basic
reproduction numbers for ...

#### Connectedness and the hyperspace of metric spaces.

(2015)

One of the prime motivations for studying hyperspaces of a metric space is to understand the
original space itself. The hyperspace of a metric space X is the space 2X of all non-empty
closed bounded subsets of it, endowed ...

#### Some aspects of semirings of functions.

(2014-02-25)

A well known fact of classical analysis is that the Stone- Cech compacti cation of a Tychono
space is achieved as the structure space of the commutative unitary ring of real valued continuous
functions de ned on it. An ...
