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

Roy, S. (author), Hermans, F.F.J. (author), Aivaloglou, E.A. (author), Winter, J. (author), van Deursen, A. (author)Spreadsheets are popular end-user computing applications and one reason behind their popularity is that they offer a large degree of freedom to their users regarding the way they can structure their data. However, this flexibility also makes spreadsheets difficult to understand. Textual documentation can address this issue, yet for supporting...conference paper 2016

Varkey, D. (author), Hicks, M.A. (author), van den Eijnden, A.P. (author)The stability of six regional dyke cross-sections in the Netherlands was re-assessed using the random finite element method (RFEM), which explicitly accounts for the spatial variability of strength parameters. The RFEM assessments of the cross-sections were shown to result in significantly narrower response distributions than those obtained...conference paper 2023

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

Kardan Halvaei, F. (author), Ahmadi, M. (author), Shekhar, A. (author), Bauer, P. (author)EV Fast chargers are crucial to alleviate the driving range anxiety for E-mobility applications. A typical converter load profile consists of a short high-current pulse to rapidly refill the EV battery followed by a cooling-off period once the charging is completed. Power electronic components experience thermal cycles as a result, which can...conference paper 2023

Molenaar, M. (author), Kardan Halvaei, F. (author), Shekhar, A. (author), Bauer, P. (author)The reliability of semiconductor power devices can be studied by performing a thermal and power cycling test. In order to create the desired temperature cycles, there are four free variables to select during the power cycling test, namely the heating current, heating time, cooling time, and heatsink temperature. In this paper, the relation...conference paper 2023

(author)An N-1 contingency can negatively affect the reliability and security of electrical power systems. A single transmission line outage can cause overload on the local healthy transmission systems, and actions are required to alleviate the overload. Traditionally the system operator uses two actions depending on the operating local area power...conference paper 2022
