“Signal Processing in the AI era” was the tagline of this year’s IEEE International Conference on Acoustics, Speech and Signal Processing, taking place in Rhodes, Greece.
In this context, Brent de Weerdt, Xiangyu Yang, Boris Joukovsky, Alex Stergiou and Nikos Deligiannis presented ETRO’s research during poster sessions and oral presentations, with novel ways to process and understand graph, video, and audio data. Nikos Deligiannis chaired a session on Graph Deep Learning, attended the IEEE T-IP Editorial Board Meeting, and had the opportunity to meet with collaborators from the VUB-Duke-Ugent-UCL joint lab.

VUB, ULB and the Brussels Capital Region government announce the launch of a new Artificial Intelligence for the Common Good Institute during the Belgian AI Week of AI4Belgium.
Today, Annemie Schaus and Caroline Pauwels, respectively rectors of ULB and VUB, were proud to announce the launch of FARI the Artificial Intelligence institute for the Common Good. It was also endorsed by the Brussels Capital Region ministers Barbara Trachte and Bernard Clerfayt.
FARI is a unique structure that aims at gathering over 300 researchers in AI (amongst others the ETRO dept) and associated disciplines, around projects that could benefit the general interest. The institute will promote research on trustworthy, transparent and explainable artificial intelligence. It will also aim at helping the Brussels Region and its inhabitants address some of the challenges they face in various domains. FARI researchers will provide ideas and contribute to projects on transportation, sustainable development, healthcare services, civic consultations on AI and algorithms. Its projects will actively involve citizens and reinforce education on AI and its impacts in the region.
The institute aims at creating a bridge between AI experts, citizens, companies and local organizations. It will have three hubs: an Research & Innovation Hub, a Think Tank on AI, Data and Society, and an AI Test and Experience Hub.

Nowadays, carbon nanomaterials are increasingly garnering attention as the next generation of semiconductor materials. Notably, graphene and carbon nanofibers (CNFs) have emerged as pivotal players in the semiconductor domain, owing to their remarkable electrical, mechanical, and thermal properties, coupled with their distinctive structural attributes.
Graphene, characterized by its two-dimensional single-layer structure of densely packed carbon atoms, boasts unparalleled electrical conductivity. This positions it for significant potential in applications like highfrequency electronic devices and sensors. Furthermore, its transparency and flexibility pave the way for innovative advancements in flexible electronic devices and display technologies, rejuvenating the electronics industry’s potential. CNFs, celebrated for their nanoscale diameter and exceptional mechanical attributes, carve a niche for themselves in material science. Their superior conductivity heralds vast opportunities, especially in realms such as conductive fibers and flexible circuitry. Within the spectrum of synthesis techniques, Chemical Vapor Deposition (CVD) emerges as a standout method, particularly for producing highquality graphene films and CNFs.
This dissertation delves into the CVD preparation, performance characterization, and subsequent applications of these materials, particularly in electromagnetic (EM) and ultraviolet (UV) optics. Specifically, the research encompasses:
- Investigating the photoluminescence (PL) performance of ZnO/graphene composite films and ZnO@CNFs composite fibers within the UV emission spectrum
- Determining the optimal thickness of ZnO in the ZnO/graphene composite for optimal UV-PL behavior
- Analyzing the anisotropic EM loss behavior of CNFs and ZnO@CNFs samples across the MMW and sub-terahertz bands
- Pioneering a novel quality-assessment method for wafer-scale CVDprepared graphene films, grounded in their distinctive interactions with terahertz TE10 waves
In essence, this research centers on graphene and CNFs, exploring their potential in the realm of EM and UV optics and offering insights based on their intrinsic properties.
