Iannarelli, A. (author), Ghaffarian Niasar, M. (author), Ross, Robert (author)Dielectric elastomer actuators (DEAs) are a class of electrostatic actuators that have promising applications in fields like sensors, soft-robotics, microfluidics, and energy harvesting. The crucial points in the working principle of DEA are the application of high electric field and the use of compliant electrodes. These electrodes are...journal article 2020

Zhong, N. (author)Thermal interface materials (TIMs) are widely used as gap–filler materials between electronic devices such as LEDs and ICs and their heat sink and aim to control the heat dissipation and to provide mechanical anchoring. As the rated power densities of electronic devices are increasing rapidly, the TIMS are exposed to higher thermal and...doctoral thesis 2020

Varkey, D. (author)This thesis utilises the random finite element method (RFEM) to provide practical guidance and tools for geotechnical engineers to account for the influence of soil spatial variability. This has involved: (a) practical insight and guidance on the choice of characteristic soil property values and scales of fluctuation; (b) a robust approach to...doctoral thesis 2020

Arous, Ines (author), Dolamic, Ljiljana (author), Yang, J. (author), Bhardwaj, Akansha (author), Cuccu, Giuseppe (author), Cudré-Mauroux, Philippe (author)Explainability is a key requirement for text classification in many application domains ranging from sentiment analysis to medical diagnosis or legal reviews. Existing methods often rely on "attention" mechanisms for explaining classification results by estimating the relative importance of input units. However, recent studies have shown that...conference paper 2021

Lee, J. (author), Mitici, M.A. (author)Predictive aircraft maintenance is a complex process, which requires the modeling of the stochastic degradation of aircraft systems, as well as the dynamic interactions between the stakeholders involved. In this paper, we show that the stochastically and dynamically colored Petri nets (SDCPNs) are able to formalize the predictive aircraft...conference paper 2021

Fu, J. (author), Nunez, Alfredo (author), De Schutter, B.H.K. (author)Preventive maintenance is applied in distribution networks to prevent failures by performing maintenance actions on components that are at risk. Distributed generators (DGs) and batteries can be used to support power to nearby loads when they are isolated due to maintenance. In this paper, a novel short-term preventive maintenance method is...journal article 2021

van Driel, W.D. (author), Bikker, J.W. (author), Tijink, M. (author)It is known that quantitative measures for the reliability of software systems can be derived from software reliability models. And, as such, support the product development process. Over the past four decades, research activities in this area have been performed. As a result, many software reliability models have been proposed. It was shown...journal article 2021

Leffler, David (author), Burghout, Wilco (author), Jenelius, Erik (author), Cats, O. (author)The paper develops a simulation model and evaluates fixed versus on-demand operational designs of a station-based automated feeder service. The evaluation considers the operational cost and average passenger level-of-service trade-offs as well as distributional differences in waiting times. Two case studies are used to evaluate such trade...journal article 2021

Seyffert, Harleigh C. (author), Kana, A.A. (author), Troesch, Armin W. (author)This paper examines the performance of 6 stiffened ship panel designs in different operational profiles. The main question of interest is: which sea states will lead to the worst panel performances in terms of reliability? As stiffened panel collapse is governed by combined lateral and in-plane loading effects (non-linear functions of the...conference paper 2021

Zhao, Xiujie (author), Chen, P. (author), Gaudoin, Olivier (author), Doyen, Laurent (author)This study proposes a framework to analyze accelerated degradation testing (ADT) data in the presence of inspection effects. Motivated by a real dataset from the electric industry, we study two types of effects induced by inspections. After each inspection, the system degradation level instantaneously reduces by a random value. Meanwhile, the...journal article 2021

Easa, Said (author), Raju, Narayana (author), Arkatkar, Shriniwas (author)Currently, the dilemma and option zones’ failures are independently used to analyze the intergreen interval at signalized intersections. Therefore, the present research work is initiated to integrate these failures. First, the dilemma and option zones are modelled using the first-order second-moment method. Then, game theory is used to model the...journal article 2022

Belgioioso, Giuseppe (author), Ananduta, W. (author), Grammatico, S. (author), Ocampo Martinez, C.A. (author)In future distribution grids, prosumers (i.e., energy consumers with storage and/or production capabilities) will trade energy with each other and with the main grid. To ensure an efficient and safe operation of energy trading, in this paper, we formulate a peer-to-peer energy market of prosumers as a generalized aggregative game, in which a...journal article 2022

Multi-objective design of aircraft maintenance using Gaussian process learning and adaptive samplingLee, J. (author), Mitici, M.A. (author)Aircraft maintenance design aims to identify strategies that render the aircraft reliable for flight in a cost-efficient manner. These are often conflicting objectives. Moreover, existing studies on maintenance design often limit themselves to only one type of maintenance strategy, overlooking other potentially dominating designs. We propose...journal article 2022
