Explainable Software Engineering in the Public Sector The field of software engineering seeks to devise theories, methods, tools, and techniques that support the development, operation, and evolution of the digital infrastructure modern society relies on. While the software engineering capabilities have advanced substantially over the past decades, it remains challenging to deliver high quality systems in a timely and cost-effective manner. Government system in particular have a weak reputation in this respect.To better understand why, we analyze 125 complex software projects in the public sector in The Netherlands. The projects are described in public reports published by the Advisory Council on IT Assessments (AcICT), which advises the Dutch parliament and cabinet on riks and chances of success in complex Information Technology (IT) projects. The projects span a time period of 10 years, represent a total budget of over 14 billion Euros, and cover such areas as tax collection, social security, pensions, health, traffic control, defense, or water management.We study these reports through the lens of "explainability", focusing on supporting decision making. Furthermore, we reflect on current advances in software engineering, including modern software testing and large language models, in addressing current software engineering challenges.

Le GIEC alerte sur l’impact croissant du réchauffement climatique sur l’eau, avec des sécheresses et inondations plus fréquentes, menaçant l’approvisionnement mondial. D’ici 2050, 42 % des bassins hydrographiques seront gravement affectés, et les dégâts liés aux inondations pourraient quadrupler en cas de réchauffement de 4 °C. Les populations les plus vulnérables, bien que peu responsables, en subissent les pires conséquences. En Wallonie, les récentes catastrophes climatiques et pollutions de l’eau illustrent ces enjeux. Pour sensibiliser le public, un événement est organisé à Charleroi avec débats et projections.Au programme17h00 | Séance d'introduction           Responsable UNESCO Belgique           Mr Aurélien Dumont, Secrétariat du Programme hydrologique intergouvernemental de l’UNESCO, Situation Mondiale de l’eau17h40 | Projection du film "H2O, l’eau, la vie et nous : l’Urgence"18h30 | Pause18h45 | Conférences et débat           Prof. Marnik Vanclooster (UCLouvain), « Situation en Wallonnie »           Prof. Alfred Bernard (UCLouvain), « Normes et toxicologie »           Débat Animé par le Prof. Karim ZouaouiBoudjeltia (ULB), avec la participation d’Aurélien Dumont, Marnik Vanclooster, Alfred Bernard.20h30 | Cocktail dinatoireGRATUIT : Inscription souhaitée : f.amer@wbi.beLes membres de la Sous-Commission « sciences exactes et naturelles »Bernard Feltz (UCLouvain, Président), Bertrand Hespel (UNamur), Marie-Geneviève Pinsart (ULB, CIGB), René Rezsohazy (UCLouvain), Frédéric Rychter (Secrétaire général), Olivier Sartenaer (UNamur), Didier Serteyn (ULiège), Anne Staquet (UMons), Marnik Vanclooster (UCLouvain), Karim Zouaoui Boudjeltia (ULB)

This thesis presents a novel approach to address the challenges of deploying and managing Network Functions Virtualization (NFV) in resource-constrained and multi-domain environments. The proposed solution leverages a Raspberry Pi clusterbased approach for NFV deployment in resource-constrained environments, combined with a deployable Sidecar VNF (S-VNF) coordinator for multi-domain NFV orchestration.The thesis demonstrates the feasibility of integrating NFV into edge computing environments by successfully deploying and managing Network Services (NSs) on a Raspberry Pi cluster. The S-VNF coordinator facilitates efficient cross-cloud VNF deployment and management while ensuring security and interoperability.While the obtained deployment and scaling delays in the testbed setup were significant due to the bare-metal deployment process used, the proposed solution remains valuable in environments where service maintenance time is a critical factor.By automating deployment and scaling, organizations can minimize the impact of service maintenance time, improve customer satisfaction, and enhance system resilience. Moreover, the solution enables NFV to be deployed effectively in edge environments, providing benefits such as reduced latency and improved network performance.Overall, this thesis contributes to the advancement of NFV by providing innovative solutions for deployment and management in challenging environments. The proposed framework has the potential to enable the widespread adoption of NFV and drive the development of new network services.Dirigée par le Prof. Laurent SCHUMACHER et le Prof. Sokchenda SRENG.Devant un jury composé de :Prof. Wim VANHOOF, Président, Université de NamurProf. Laurent SCHUMACHER, Co-Promoteur, Université de NamurProf. Sokchenda SRENG, Co-Promoteur, ITC Graduate School (Cambodge)Prof. Florentin ROCHET, Membre interne, Université de NamurProf. Johann MARQUEZ-BARJA, Membre externe, Université d’AnversProf. Bruno QUOITIN, Membre externe, Université de MonsProf. Raveth HIN, Membre externe, ITC Graduate School (Cambodge)Vous êtes cordialement invités à un drink, qui suivra la soutenance publique.Pour une bonne organisation, merci de donner votre réponse pour le jeudi 20 mars.Contact : Daelman Isabelle – isabelle.daelman@unamur.be

Le Professeur Timoteo Carletti de l’Université de Namur vient de publier dans la prestigieuse revue Nature Physics en collaboration avec la Professeure Ginestra Bianconi de l’Université Queen Mary de Londres et huit autres chercheurs internationaux. Cette étude révolutionnaire pourrait conduire au développement de nouveaux algorithmes d’IA, à de nouvelles façons d’étudier le fonctionnement du cerveau ou encore à des percées dans des disciplines telles que la physique, la science du climat, la finance et bien d’autres.

Abstract Over the past two centuries, advances in healthcare have significantly extended life expectancy by reducing the impact of many diseases. As this progress continues, attention shifts toward more complex illnesses, with cancer emerging as the foremost challenge. Photodynamic therapy (PDT) is a light-activated cancer treatment approved in 1995 that offers a targeted approach by using photosensitizers (PSs) — compounds that, upon light activation, generate reactive singlet oxygen to selectively damage tumor tissue. However, current commercial PSs suffer from several drawbacks: ill-defined composition, poor accumulation in tumors and slow clearance, limited application depths, and insufficient fluorescence for diagnostic imaging. This thesis addresses these limitations by pursuing the development of efficient and partially fluorescent PSs that absorb strongly in the red to near-infrared (NIR) range. The first part of the work focuses on computational tools based on quantum chemistry, particularly density functional theory, to predict molecular properties relevant to PDT. These methods are benchmarked and refined to ensure accurate and efficient screening of candidate compounds. Additionally, a commonly used metric for quantifying charge transfer distance in excited states is reformulated to be independent of molecular symmetry, allowing broader and more robust applicability. In the second part, these tools guide the design of novel PSs. One strategy involves modifying pyrrolopyrrole aza-BODIPY dyes into donor–acceptor structures to enable singlet oxygen generation via spin–orbit charge transfer intersystem crossing (SOCT-ISC). Another approach focuses on a twisted BODIPY compound that achieves photosensitization by facilitating ISC through a distortion of the symmetry. This PS is tuned to absorb NIR light and, in some cases, leverage the SOCT-ISC mechanism. Overall, these efforts did not only yield promising PSs but also provided computational insights to accelerate future developments in the field.

La pandémie de Covid-19 est une tragédie humaine qui a causé des millions de morts à travers le monde et mis en grande tension toute notre société. Mais elle a aussi été un formidable moment collectif pour de nombreux scientifiques de l'UNamur, dont les recherches se poursuivent pour tenter de mieux comprendre cette maladie et ses conséquences.
