Ricci, Diletta (author), Konstantinou, T. (author), Visscher, H.J. (author)The renovation of existing buildings is widely recognized as a powerful strategy for reducing emissions and land use. However, when it comes to residential buildings, the socio-technical challenges are particularly complex. The necessity and urgency of increasing energy efficiency often lead to retrofit processes that overlook residents’ needs...conference paper 2024

Križanović, Josip (author), Roić, Miodrag (author), Pivac, Doris (author)Land administration (LA) is dynamic, and it cannot be understood, built or improved unless the processes associated with it are understood. One of the core standards in the domain of LA, namely ISO 19152 Land Administration Domain Model (LADM) provides conceptual data models for land administration systems (LASs). However, it does not cover all...conference paper 2023

(author), Farahani, Reza (author)Our society is increasingly digital, and its processes are increasingly digitalized. As an emerging technology for the digital society, graphs provide a universal abstraction to represent concepts and objects, and the relationships between them. However, processing graphs at a massive scale raises numerous sustainability challenges; becoming...conference paper 2023

Herrera-Semenets, Vitali (author), Bustio-Martínez, Lázaro (author), Hernández-León, Raudel (author), van den Berg, Jan (author)Decision trees are one of the most popular structures for decision-making and the representation of a set of rules. However, when a rule set is represented as a decision tree, some quirks in its structure may negatively affect its performance. For example, duplicate sub-trees and rule filters, that need to be evaluated more than once, could...conference paper 2023

Supporting Children’s Metacognition with a Facial Emotion Recognition based Intelligent Tutor SystemRuan, Xingran (author), Palansuriya, Charaka (author), Constantin, Aurora (author), Tsiakas, K. (author)The present study aims to investigate the relationship between emotions experienced during learning and metacognition in typically developing (TD) children and those with autism spectrum disorder (ASD). This will assist us in using machine learning (ML) to develop a facial emotion recognition (FER) based intelligent tutor system (ITS) to...conference paper 2023

Hoftijzer, J.W. (author), Carelsberg, H.M. (author), Sypesteyn, M. (author)There is a growing interest in the discipline of design sketching and drawing. Whereas its origin lies in the sketching and presenting of tangible (industrially designed) products, the discipline has, since approximately 2010, extended in various ways, along various dimensions. Various authors have addressed and discussed the most prominent...conference paper 2023

Agiollo, A. (author), Cavalcante Siebert, L. (author), Murukannaiah, P.K. (author), Omicini, Andrea (author)Although popular and effective, large language models (LLM) are characterised by a performance vs. transparency trade-off that hinders their applicability to sensitive scenarios. This is the main reason behind many approaches focusing on local post-hoc explanations recently proposed by the XAI community. However, to the best of our knowledge,...conference paper 2023

Kruse, N.C. (author), Fioranelli, F. (author), Yarovoy, Alexander (author)Due to numerous benefits, radar is considered as an important sensor for human activity classification. The problem of classifying continuous sequences of activities of unconstrained duration has been studied in this work. To tackle this challenge, a radar data processing method utilizing point transformer networks has been proposed. The method...conference paper 2023

Guendel, Ronny (author), Ullmann, I. (author), Fioranelli, F. (author), Yarovoy, Alexander (author)Radar-based human activity recognition in crowded environments using regression approaches is addressed. Whereas previous research has focused on single activities and subjects, the problem of continuous activity recognition involving up to five individuals moving in arbitrary directions in an indoor area is introduced. To treat the problem, a...conference paper 2023

Yuan, S. (author), Fioranelli, F. (author), Yarovoy, Alexander (author)The ambiguity problem in forward-looking Doppler beam sharpening is considered. Doppler beam sharpening (DBS) has shown its potential to improve cross-range resolution for automotive radar applications. However, it suffers from ambiguities when targets are positioned symmetrically with respect to the vehicle trajectory. A new approach named ...conference paper 2023

van der Hoeven, Jelmer (author), Natali, A. (author), Leus, G.J.T. (author)Forecasting time series on graphs is a fundamental problem in graph signal processing. When each entity of the network carries a vector of values for each time stamp instead of a scalar one, existing approaches resort to the use of product graphs to combine this multidimensional information, at the expense of creating a larger graph. In this...conference paper 2023

(author), Anitori, Laura (author)Integrated sidelobe level is a useful measure to quantify robustness of a waveform-filter pair to unknown range clutter and multiple closely located targets. Sidelobe suppression on receive will incur a loss in the signal to noise ratio after pulse compression. We derive a pulse compression filter that has the greatest integrated sidelobe...conference paper 2023

(author)Under in-plane compressive load conditions, the growth of a delamination initially induced by an impact can be followed by a fast growth after a threshold level, which leads to a catastrophic failure in composite structures. To avoid reaching this critical level, it is essential to uncover the delamination size and growth pattern in real time....conference paper 2023
