#### Computing the Greeks using the integration by parts formula for the Skorohod integral

(Stellenbosch : Stellenbosch University, 2008-03)

The computation of the greeks of an option is an important aspect of financial
mathematics. The information gained from knowing the value of a greek of
an option can help investors decide whether or not to hold on to or ...

#### Off-line signature verification

(Stellenbosch : University of Stellenbosch, 2005-03)

A great deal of work has been done in the area of off-line signature verification over the
past two decades. Off-line systems are of interest in scenarios where only hard copies of
signatures are available, especially ...

#### The transfer of distributions by LULU smoothers

(Stellenbosch : Stellenbosch University, 2008-12)

LULU smoothers is a class of nonlinear smoothers and they are compositions
of the maximum and minimum operators. By analogy to the discrete Fourier
transform and the discrete wavelet transform, one can use LULU smoothers
to ...

#### 'n Studie van die konveksiteitstelling van A.A. Lyapunov

(Stellenbosch : University of Stellenbosch, 2008-03)

Let T be a non-empty set, A a u-algebra of subsets of T and u : .A -+ Rn a bounded,
countably additive measure. A set E E A is called an atom with respect to u if u(E)=/F 0
and, if F E A, FeE, then u(F) = u(E) or u(F) = ...

#### Cardinal spline wavelet decomposition based on quasi-interpolation and local projection

(Stellenbosch : University of Stellenbosch, 2009-03)

Wavelet decomposition techniques have grown over the last two decades into a powerful tool
in signal analysis. Similarly, spline functions have enjoyed a sustained high popularity in the
approximation of data.
In this ...

#### Iwasawa theory for elliptic curves

(Stellenbosch : Stellenbosch University, 2006-04)

ENGLISH ABSTRACT: In this thesis we consider modules over the Iwasawa algebra, these naturally arise in the classical theory
of class groups over cyclotomic fields as exposed by Kenkichi Iwasawa. We classify these modules ...

#### Regulated rewriting in formal language theory

(Stellenbosch : University of Stellenbosch, 2008-03)

Context-free grammars are well-studied and well-behaved in terms of decidability, but many
real-world problems cannot be described with context-free grammars. Grammars with regulated
rewriting are grammars with mechanisms ...
