Source model extraction---the automated extraction of information from system artifacts---is a common phase
in reverse engineering tools. One of the major challenges of this phase is creating extractors that can deal with
irregularities in the artifacts that are typical for the reverse engineering domain (for example, syntactic errors,
incomplete source code, language dialects and embedded languages).

A domain-specific language (DSL) provides a notation tailored towards an application domain and is based on
the relevant concepts and features of that domain. As such, a DSL is a means to describe and generate members
of a family of programs in the domain.

Quality of Service (QoS) protocols and architectures play an important role in distributed multimedia systems
since multimedia presentations need to be played for the user without stalls, necessitating guaranteed
response times. However in the Internet no other QoS than best--e#ort is given. This report investigates
some QoS architectures and protocols designed to overcome these limitations and looks at the applications
of these protocols for multimedia systems.

Many dependencies appear between the di#erent stages of the creation of a hypermedia presentation. These
dependencies have to be taken into account while designing a system for their automatic generation. In this
work we study two of them and propose some techniques to treat them. During this process, we introduce the
partial design of a hypermedia formatting model that we call Hypermedia Formatting Objects.

Of the various programming paradigms in use today, object-orientation is probably the most successful in
terms of industrial take-up and application, particularly in the field of multimedia. It is therefore unsurprising
that this technology has been adopted by ISO/IEC JTC1/SC24 as the foundation for a forthcoming
International Standard for Multimedia, called PREMO. Two important design aims of PREMO are that it be
distributable, and that it provide a set of media-related services that can be extended in a disciplined way to
support the needs of future applications and problem domains. While key aspects of the object-oriented
paradigm provide a sound technical basis for achieving these aims,...

Learning one class at a time can be seen as an eective solution to classi
cation problems
in which only the positive examples are easily identi
able. A kernel method to accomplish this
goal consists of a representation stage - which computes the smallest sphere in feature space
enclosing the positive examples - and a classi
cation stage - which uses the obtained sphere
as a decision surface to determine the positivity of new examples. In this paper we describe a
kernel well suited to represent, identify, and recognize 3D objects from unconstrained images.

With the rapid growth of interest in the Internet as a means for accessing multimedia
presentations for education, entertainment and commerce, comes a corresponding need for
systems to supply automatically generated, personalised presentations. Multimedia is a rich and
complex genre of resources and the interrelated effects of content, style and structure ensure
that automatic presentation generation is in itself a complicated and challenging task.

The Semantic Web envisions a Web that is both human readable and machine processible. In
practice, however, there is still a large conceptual gap between annotated content repositories
on the one hand, and coherent, human readable Web pages on the other. To bridge this
conceptual gap, one needs to select the appropriate content from the repository, structure and
order the material, and design a Web page that effectively conveys the selected content and the
chosen structure. In addition to this conceptual gap, there is also a technological gap. On one
side of this gap, we find the semantic-oriented technology deployed to build annotated content
repositories. This includes...

The "Document Web" has established itself through the creation of an impressive family of XML
and related languages. In addition to this, the "Semantic Web" is developing its own family of
languages based primarily on RDF. Although these families were both developed specifically for
"the Web", each language family has been developed from different premises with specific
goals in mind. The result is that combining both families in a single application is surprisingly
difficult. This is unfortunate, since the combination of semantic processing with document
processing provides advantages in both directions --- namely using semantic inferencing for
more intelligent document processing and using document processing tools for...

The extended backward differentiation formulas (EBDFs) and their modified form (MEBDF) were proposed by
Cash in the 1980s for solving initial-value problems (IVPs) for stiff systems of ordinary differential equations
(ODEs). In a recent performance evaluation of various IVP solvers, including a variable-step-variable-order
implementation of the MEBDF method by Cash, it turned out that the MEBDF code often performs more
efficiently than codes like RADAU5, DASSL and VODE. This motivated us to look at possible parallel implementations
of the MEBDF method. Each MEBDF step essentially consists of successively solving three
nonlinear systems by means of modified Newton iteration using the same Jacobian matrix. In a direct...
