Course Contents

Each year, the University of Antwerp invites a number of experts in the field of Computer Science, to give a presentation about their work, in order to expose students to new and emerging trends. For already the fourth consecutive year now, we organize some of these seminars in conjunction with two associated institutions, namely the "Hogeschool Antwerpen" and the "Karel De Grote Hogeschool". As such, we aim to foster cross-fertilization between the closely related fields of ICT and Computer Science.

This year, the seminar will be organized as a series of lectures around the topics "Tools for Software Engineering" and "Telecom" (Telecommunicatienetwerken). Below is the tentative list of lectures that will be provided for each topic.

GROOVE (Graph-Based State Spaces)

Speaker
Prof. Dr. A. Rensink
Universiteit Twenthe
Abstract
We intend to verify object-oriented software through model checking, by representing program states as graphs and execution steps as derivations from graph production rules. We propose the resulting state space model as an alternative to traditional, state vector- based models. In this talk I will discuss the pros and cons of this approach, touching upon diverse aspects such as algorithmic complexity, symmetries, partial order reduction, representation techniques, logics for expressing properties, and abstraction. The approach has been partially implemented in a state space generation tool "GROOVE" (Graphs for Object-Oriented Verification), which I will also demonstrate.

Between rigor and usability: the process modeling tool Protos

Speaker
Dr. Hajo Reijers
TU Eindhoven
Abstract
Business processes modeling is a popular activity in industry. Model of business processes can be used for many different purposes, such as: the analysis and subsequent redesign of that process (e.g. BPR [2]), the introduction of a quality system within that process (e.g. ISO), the development of software that supports (parts of) the process, the implementation of a workflow management system to manage the process [1], the introduction of a cost accounting system (e.g. Activity Based Costing) and the demonstration of compliance to various regulations (e.g. Sarbanes Oxley).

Because of this multitude of goals, it is perhaps no suprise that many different techniques and tools have emerged to support the modeling of business processes. In particular graphical approaches such as the UML, EPC's and IDEF have become prevalent in industry. In the academic world, Petri nets have become quite popular, especially for the purpose of business process modeling [1]. This popularity has resulted in various proposed Petri net variants [3]. What is interesting here is that in business, ease of use and market leadership are the factors that will make a process modeling tool attractive. In the academic world, much more emphasis is placed on the expressiveness and well-foundedness of the underlying modeling technique.

The process modeling tool Protos [4,6] is of interest as it attempts to combine the best of both worlds. Current versions of Protos are in use by hundreds of organizations in more than 25 countries. Although it originally was introduced as an informal, easy-to-use graphical modeling tool, Petri net semantics have been incorporated in the past years. As a result, a whole variety of possibilities emerged to extend the tool with analytical capabilities, which - curiously enough - prove to be very practical in business life. The lecture will give an overview of the tool Protos, as well of the past and current developments.

Electronic ID

Speaker
Ronny Depoortere
PASS Zetes
Abstract
De elektronische identiteitskaart die iedere Belg ten laatste in 2009 bezit, biedt enorm veel mogelijkheden. Om een beter inzicht te krijgen in de eID zullen eerst de elektronische elementen en de fysische beveiliging besproken worden. Daarna zal verder ingegaan worden op de mogelijke toepassingen, de beschikbare tools via rijksregister en fedict. Tot slot komen de eID-shop, de eID kaartlezer en de evolutie aan bod.

De elektronische variant van de Belgische identiteitskaart (eID) gaat onder meer dienen om onzekerheid over de leeftijd van MSN-chatters weg te halen. Dat kondigde Bill Gates aan op 1 februari 2005 bij zijn bezoek aan ons land. De Microsoft-oprichter had verder lof over het initiatief dat hij "de meest secure identiteitsverificatie die Microsoft ooit heeft gezien" noemde.

VoIP en QoS door een checkpoint-Firewall

Speaker
Peter Sandkuijl
Checkpoint
Abstract
Met de voortgang van de technologie zien we in de markt een verdergaande acceptatie van Voice over IP verkeer. Dit verkeer wordt ervaren als bedrijfskritisch en dient ter allen tijde beschikbaar en performant te zijn. Nu voice ook over hetzelfde netwerk als dataverkeer wordt getransporteerd, opent dit ook een reeks van mogelijke kwetsbaarheden, aangezien veel meer toegang mogelijk is naar de verkeersstromen. Zaken als Denial of Service (DoS) worden plotseling actueel. In de presentatie komen de verschillende VoIP toepassingen aan bod.

De problematiek die geïntroduceerd wordt vanwege de opbouw van de verkeersstromen en de beveiligign van dat verkeer worden behandeld. Naast een goede inspectie van het verkeer dient er ook een Quality of Service aanwezig te zijn, aangezien VoIP verkeer geen zaken als ruis of vertraging mag introduceren. Bandbreedte beheer in relatie tot VoIP is de tweede topic die behandeld wordt in de presentatie.

Model Checking with Spin

Speaker
Dr. Maurice ter Beek,
ISTI-CNR
(Istituto di Scienza e Tecnologie dell'Informazione -
Consiglio Nazionale delle Ricerche)
Abstract
Model checking is an automatic technique to verify whether or not a system design satisfies its specifications. Such a verification is moreover exhaustive, i.e. all possible input combinations and states are taken into account. To avoid running out of memory due to a state-space explosion - which would make an exhaustive verification impossible - often a simplified model is used that captures the core of the system design but abstracts from unnecessary details. One of the best known and most successful model checkers is Spin, which was developed at Bell Labs during the last two decades. It is freely available through spinroot.com and it is very well documented.

Spin's input language is Promela, a non-deterministic C-like specification language for modelling finite-state systems communicating through channels. Specifications in Promela can be fed to Spin, together with a request to verify certain correctness properties. Spin then converts the Promela processes into finite-state automata and on-the-fly creates and traverses the state space of a product automaton over these finite-state automata, in order to verify the specified correctness properties. There are several ways of formalising correctness properties in Promela. One way is to add labels to the Promela specification to mark specific points in the specification, which can then be used to formulate LTL properties and to test their validity by running Spin. LTL stands for Linear Temporal Logic and it is an extension of predicate logic that allows one to express assertions about behaviour in time, without explicitly modelling time.

I will begin this talk by briefly recalling some notions from automata theory that underly Spin. Subsequently I will explain the model checker Spin, its input language Promela, and LTL in more detail. Finally, I will show an application of model checking with Spin to an industrial case study.

Aspect Oriented Software Development

Speaker
Kris Deschutter,
Universiteit Gent
Abstract
Aspect Orientation is an emerging paradigm for software-development which allows one to define concerns which crosscut an entire application in a modular way; something which is often impossible to do using Object Orientation. This talk will give an overview of the history and the ideas behind this new technology, which IBM has already outed as mission critical for its business. We will discuss some of the various views on what AOP is (or is thought to be), while showing some of the different tools under development today.

One conclusion has already been drawn though: whatever the programming language of tomorrow turns out to be, it will definitely contain some form of aspects.
