Multiple outlier detection and cluster analysis of multivariate normal data
(Stellenbosch : Stellenbosch University, 2003-12)
ENGLISH ABSTRACT: Outliers may be defined as observations that are sufficiently aberrant to arouse the
suspicion of the analyst as to their origin. They could be the result of human error, in
which case they should be ...
Optimal management of MPLS networks
(Stellenbosch : Stellenbosch University, 2002-03)
ENGLISH ABSTRACT: Multiprotocol Label Switching (MPLS) is a routing technology which can manage Quality of
Service (QoS) in scalable connectionless networks using relatively simple packet forwarding mechanisms.
This ...
Traffic engineering label switched paths
(Stellenbosch : Stellenbosch University, 2002-03)
ENGLISH ABSTRACT: The Internet is evolving into a commercial platform requiring enhanced protocols and an expanded
physical infrastructure allowing a better delivery from IP. Multi-protocol Label Switching (MPLS)
is a ...
Spectrum preserving linear mappings between Banach algebras
(Stellenbosch : Stellenbosch University, 2003-04)
ENGLISH ABSTRACT: Let A and B be unital complex Banach algebras with identities 1 and I'
respectively. A linear map T : A -+ B is invertibility preserving if Tx is
invertible in B for every invertible x E A. We say that ...
Reinforcement learning for routing in communication networks
(Stellenbosch : Stellenbosch University, 2003-04)
ENGLISH ABSTRACT: Routing policies for packet-switched communication networks must be able to adapt
to changing traffic patterns and topologies. We study the feasibility of implementing
an adaptive routing policy using ...
Hidden Markov models for on-line signature verification
(Stellenbosch : Stellenbosch University, 2002-12)
ENGLISH ABSTRACT: The science of signature verification is concerned with identifying individuals by their handwritten
signatures. It is assumed that the signature as such is a unique feature amongst
individuals and the ...
Implementation and evaluation of two prediction techniques for the Lorenz time series
(Stellenbosch : Stellenbosch University, 2003-03)
ENGLISH ABSTRACT: This thesis implements and evaluates two prediction techniques used to forecast deterministic chaotic
time series. For a large number of such techniques, the reconstruction of the phase space ...
The modelling of TCP traffic in MPLS networks
(Stellenbosch : Stellenbosch University, 2003-04)
ENGLISH ABSTRACT: The Internet has experienced tremendous growth in the last three decades and has emerged as a
platform to carryall forms of communications including voice, video and data. Along with this
growth came ...
Fredholm theory in general Banach algebras
(Stellenbosch : University of Stellenbosch, 2010-03)
ENGLISH ABSTRACT: This thesis is a study of a generalisation, due to R. Harte (see [9]), of Fredholm
theory in the context of bounded linear operators on Banach spaces
to a theory in a Banach algebra setting. A bounded ...
Investigating credit based mechanisms for enhancing performance in wireless ad hoc networks
(Stellenbosch : Stellenbosch University, 2012-12)
ENGLISH ABSTRACT: This thesis explores two key aspects of wireless ad hoc networks. The first aspect concerns the topic of stimulating cooperation between nodes in a wireless ad hoc network. The functionality of a wireless ...
