Alimohammadi, H. (author), Vassiljeva, K. (author), Hassan HosseinNia, S. (author), Ellervee, P. (author), Petlenkov, E. (author)This paper examines the stability implications of integrating piezoelectric actuators into metamaterial beams, focusing on the compensation of structural damping and its effect on the system's dynamic performance. Metamaterials, characterized by their unique bandgap properties, offer potential in various engineering applications, including...conference paper 2024

Mulder, W.A. (author)To estimate the depth errors in a subsurface model obtained from the inversion of seismic data, the stationary-phase approximation in a two-dimensional constant-velocity model with a dipped reflector is applied to migration with a time-shift extension. This produces two asymptotic solutions: one is a straight line, and the other is a curve....journal article 2024

Alpizar Castillo, J.J. (author), Ramirez Elizondo, L.M. (author), Bauer, P. (author)The urge to reduce the dependence on natural gas for heating at the residential level has led to the deployment of different fossil fuel-free alternatives. In the Netherlands, two technologies are leading the transition: heat pumps, due to their high COP, and photovoltaic–thermal systems, due to their dual electric-thermal output. However,...journal article 2024

Marchiori, Francesco (author), Conti, M. (author)The growing integration of vehicles with external networks has led to a surge in attacks targeting their Controller Area Network (CAN) internal bus. As a countermeasure, various Intrusion Detection Systems (IDSs) have been suggested in the literature to prevent and mitigate these threats. With the increasing volume of data facilitated by the...conference paper 2024

Ricci, Federica (author), Yang, M. (author), Reniers, G.L.L.M.E. (author), Cozzani, Valerio (author)Emergency response is a procedural safety barrier of paramount importance for the mitigation of fire scenarios and the prevention of escalation. However, in Natech scenarios, emergency response may be affected by the natural event impacting the site. Indeed, when contrasting Natech accidents, emergency responders have to face both the natural...journal article 2024

Zahedi, M.Z. (author)Computation-in-Memory (CIM) is a promising alternative to traditional computing systems where the storage is conceptually separated fromthe computing units. Instead, the CIM paradigm aims to perform the computation where the data resides, alleviating the memory bottleneck and ultimately leading to higher energy efficiency and performance. From...doctoral thesis 2023

Balayn, A.M.A. (author)Machine learning (ML) is an artificial intelligence technology that has a great potential for being adopted in various sectors of activities. Yet, it is now also increasingly recognized as a hazardous technology. Failures in the outputs of an ML system might cause physical or social harms. Besides, the development and deployment of an ML system...doctoral thesis 2023

Diab, I. (author)Electricity grids are increasingly congested as the world moves toward a sustainable, electrified future. Expanding and upgrading these infrastructures is costly and challenging on a technical and administrative level and even redundant when considering that some sub-parts of these grids, such as electric transportation networks, are massively...doctoral thesis 2023

Delle Donne, C. (author)Computer networks have been one of the most revolutionary concepts and technologies of the last fifty years. Currently, it is arguably impossible to imagine a world without the internet. And yet, just five decades ago, hardly anybody knew what it even meant. Today, the first quantum computer networks are starting to take shape, along with the...doctoral thesis 2023

Machado Lima de Camargo, C. (author)As a result of climate change, sea level is changing all over the world at unprecedented rates. Sea-level change can have significant impacts on coastal communities, infrastructure and global economy, as most of the major cities are located near to or at the coast. Rising sea levels can lead to, for instance, more severe and more frequent...doctoral thesis 2023

Sabzehee, F. (author), Amiri Simkooei, A. (author), Iran Pour, S. (author), Vishwakarma, B.D. (author), Kerachian, R. (author)The Urmia lake in north-west Iran has dried up to perilously low levels in the past two decades. In this study, we investigate the drivers behind the decline in lake water level with the help of in-situ and remote sensing data. We use total water storage (TWS) changes from the gravity recovery and climate experiment (GRACE) satellite mission....journal article 2023

Mohamed, Ahmed (author), Abdelrady, Ahmed (author), Alarifi, Saad S. (author), Othman, Abdullah (author)Because of climate change and human activity, North and Central Africa are experiencing a significant water shortage. Recent advancements in earth observation technologies have made widespread groundwater monitoring possible. To examine spatial and temporal mass fluctuations caused by groundwater variations in Chad, gravity solutions from the...journal article 2023

Sileryte, R. (author), Wandl, Alex (author), van Timmeren, A. (author)With circular economy being high on governmental agendas, there is an increasing request from governing bodies for circularity measurements. Yet, currently existing macro-level monitoring frameworks are widely criticized for not being able to inform the decision-making. The criticism includes, among others, a lack of consensus on...journal article 2023

Howard, Thomas (author), Driller, K.K. (author), Frier, William (author), Pacchierotti, Claudio (author), Marchal, Maud (author), Hartcher-O'Brien, J. (author)Ultrasound mid-air haptic (UMH) devices are a novel tool for haptic feedback, capable of providing localized vibrotactile stimuli to users at a distance. UMH applications largely rely on generating tactile shape outlines on the users' skin. Here we investigate how to achieve sensations of continuity or gaps within such two-dimensional curves...journal article 2023

It has caused a significant exogenous shock that offers a wealth of natural experiments and produced new data about broadband, clouds, and the Internet in times of crisis. In this chapter, we characterise and...book chapter 2023

(author), Feldmann, Anja (author), Gasser, Oliver (author), Fiebig, Tobias (author)DNS is one of the core building blocks of the Internet. In this paper, we investigate DNS resolution in a strict IPv6-only scenario and find that a substantial fraction of zones cannot be resolved. We point out, that the presence of an AAAA resource record for a zone’s nameserver does not necessarily imply that it is resolvable in an IPv6-only...conference paper 2023
