Gama, F. (author), Marques, Antonio G. (author), Leus, G.J.T. (author), Ribeiro, Alejandro (author)In this ongoing work, we describe several architectures that generalize convolutional neural networks (CNNs) to process signals supported on graphs. The general idea of the replace time invariant filters with graph filters to generate convolutional features and to replace pooling with sampling schemes for graph signals. The different...conference paper 2019

Shareef, A. (author), Taneja, P. (author), Van Schuylenburg, M. (author)The Maldives is a Small Island Developing State which depends on sea-borne transport connectivity for trade and inclusive nationwide growth. The high international freight costs to its small domestic market are aggravated by deficiencies in services and capacity in the Port of Male', the sole maritime gateway to the country. Male' City is the...conference paper 2019

Gavin, Kenneth (author), Broere, W. (author), Kovacevic, M. S. (author), de Haas, K. (author)In this paper we present issues related to the performance of immersed tube tunnels in the Netherlands. A range of issues are experienced for the ageing structures including long-term settlement at tunnel joints and consequent leakage. Because of the age of these structures some important aspects are often unknown thus creating uncertainty...conference paper 2019

Diambra, A. (author), Corti, R. (author), Liu, H. (author), Pisano, F. (author), Abell, J. A. (author)This paper presents an objective comparison between two recent constitutive models employing the concept of the hardening memory surface to predict the high cyclic loading behaviour of granular soils. The hardening memory surface is applied to the well-known Severn-Trent sand and the SANINSAND04 constitutive models. While the addition of the new...conference paper 2019

Neustroev, G. (author), de Weerdt, M.M. (author), Verzijlbergh, R.A. (author)Infinite-horizon non-stationary Markov decision processes provide a general framework to model many real-life decision-making problems, e.g., planning equipment maintenance. Unfortunately, these problems are notoriously difficult to solve, due to their infinite dimensionality. Often, only the optimality of the initial action is of importance to...conference paper 2019

Gonzalez Saiz, G. (author), Sciacchitano, A. (author), Scarano, F. (author)The time-segment assimilation (TSA) method levers upon the spatio-temporal information from a finite number of successive time samples of particle velocity, coming from PTV and STB, into a refined spatial reconstruction of the velocity field of the flow. The method recently introduced by Schneiders and Scarano (2018) is elaborated here further...conference paper 2019

Aslan, Y. (author), Puskely, J. (author), Roederer, A.G. (author), Yarovoy, Alexander (author)The thermal and electromagnetic effects of varying the ground plane thickness and aperture size of the 5G integrated base station antennas are investigated. A double-sided PCB structure is designed with antennas and digital beamforming chips on the opposite sides. Fully-passive cooling is achieved by using fanless CPU coolers attached to the...conference paper 2019

Gujarati, Arpan (author), Nasri, Mitra (author), Majumdar, Rupak (author), Brandenburg, Björn B. (author)Estimating metrics such as the Mean Time To Failure (MTTF) or its inverse, the Failures-In-Time (FIT), is a central problem in reliability estimation of safety-critical systems. To this end, prior work in the real-time and embedded systems community has focused on bounding the probability of failures in a single iteration of the control loop,...conference paper 2019

He, Z. (author), Sun, P. (author), Van Mieghem, P.F.A. (author)Network recoverability refers to the ability of a network to return to a desired performance level after suffering malicious attacks or random failures. This paper proposes a general topological approach and recoverability indicators to measure the network recoverability in two scenarios: 1) recovery of damaged connections and 2) any...conference paper 2019

van der Sar, T. (author)Spin waves are the elementary spin excitations of magnetic materials. This paper presents the use of nitrogen-vacancy spins in diamond to study spin-wave resonances, thermally excited spin waves, and spin-wave chemical potentials. These techniques open up new possibilities for nanoscale imaging and control of spin transport in mesoscopic spin...conference paper 2019
