Xu, F. (author), Hajibeygi, H. (author), Sluys, Lambertus J. (author)Deformable fractured porous media appear in many geoscience applications. While the extended finite element method (XFEM) has been successfully developed within the computational mechanics community for accurate modeling of deformation, its application in geoscientific applications is not straightforward. This is mainly due to the fact that...journal article 2021

Psarakis, Kyriakos (author)Schema matching is a fundamental task in the data integration pipeline and has been studied extensively in the past decades, leading to many novel schema matching methods. However, these methods do not follow a standard evaluation process, leading to uncertainty in which one performs best in matching accuracy and runtime constraints, and in...master thesis 2020

Proost, Rick (author)Monitoring software behaviour is being done in various ways. Log messages are being output by almost any kind of running software system. Therefore, learning how software behaves from doing analysis over log data can lead to new insights about the system. However, the number of log messages in a computer system grow fast, and analysing the log...master thesis 2020

Dekker, Quinten (author)Dense 3D modeling based on monocular visual data is a powerful process of gaining spatial 3D understanding from 2D observations. The use of visual data to reconstruct such 3D models is still a challenging topic. To obtain the accurate dimensions, additional metadata is required such as a GPS which is not always available. Besides this, dealing...master thesis 2020

Snel, Koen (author)The ongoing demand for bigger and more efficient ships pushes their designs towards the strength limits. Sometimes, ship structures are pushed beyond their limits with the possibility of significant negative economic and environmental impact or, in the worst case, impact on human life. This makes it explicitly clear why the development of...master thesis 2020

van der Harst, Stefan (author)In the super-yacht industry, value is added by customisation of design. From an engineering perspective, standardisation contributes to working more efficiently and effectively and thus less costly. The perspective of naval architecture company C-Job is that standardisation can contribute to engineering lead time reduction. Since customisation ...master thesis 2020

Kersten, W.C. (author)The problem: Design challenges are becoming increasingly complex, amongst others because real life is getting more complex. Society is more interconnected than before and most problems occur in a variety of -quickly changing- shapes and forms, i.e. in different contexts. These contexts pose different requirements and often have interdependencies...doctoral thesis 2020

Kouvelas, N. (author), Rao, V.S. (author), Venkatesha Prasad, Ranga Rao (author), Tawde, G.C. (author), Langendoen, K.G. (author)Long Range Wide Area Network (LoRaWAN) covers the needs of energy-constrained IoT-devices for operational longevity and extended communication range in a best-effort fashion. However, Lo- RaWAN’s minimalist design cannot handle the traffic from dense deployments with more than a few hundred devices connected to a single gateway, since each LoRa...conference paper 2020

Brouwer, Jetse (author)Distributed ledger technology was expected to spark a technical revolution similar to the internet revolution. After the release of Bitcoin in 2008, many developments have significantly increased the performance of distributed ledger technology. Nevertheless, the first truly scalable ledger has yet to be deployed. All of them have issues with...master thesis 2020

Yu, Cunming (author), Sasic, Srdjan (author), Liu, Kai (author), Salameh, S. (author), Ras, Robin H.A. (author), van Ommen, J.R. (author)Nature-inspired self-cleaning surfaces have attracted considerable attention from both fundamental research and practical applications. This review adopts a chemical-engineering point of view and focuses on mechanisms, modelling, and manufacturing (M3) of nature-inspired self-cleaning surfaces. We will introduce six nature-inspired self...journal article 2020

Klemke, Roland (author), Antonaci, Alessandra (author), Limbu, B.H. (author)Gamification aims at addressing problems in various fields such as the high dropout rates, the lack of engagement, isolation, or the lack of personalisation faced by Massive Open Online Courses (MOOC). Even though gamification is widely applied, not only in MOOCs, only few cases are meaningfully designed and empirically tested. The...journal article 2020

Dwarka, V.N.S.R. (author), Vuik, Cornelis (author)Recent research efforts aimed at iteratively solving the Helmholtz equation have focused on incorporating deation techniques for accelerating the convergence of Krylov subpsace methods. The requisite for these efforts lies in the fact that the widely used and well-acknowledged complex shifted Laplacian preconditioner (CSLP) shifts the...journal article 2020

Al-Ars, Z. (author), Wang, S. (author), Mushtaq, H. (author)The rapid proliferation of low-cost RNA-seq data has resulted in a growing interest in RNA analysis techniques for various applications, ranging from identifying genotype–phenotype relationships to validating discoveries of other analysis results. However, many practical applications in this field are limited by the available computational...journal article 2020

Olieman, C. (author), Bouter, P.A. (author), Bosman, P.A.N. (author)The recently introduced real-valued gene-pool optimal mixing evolutionary algorthm (RV-GOMEA) has been shown to be among the state of the art for solving gray-box optimization problems where partial evaluations can be leveraged. A core strength is its ability to effectively exploit the linkage structure of a problem, which often is unknown a...journal article 2020

Shiferaw, Yonatan (author)LoRaWAN is amongst the most prominent LPWAN (Low Power Wide Area Networking) technologies and provides an operation mode, called Class B, where devices can be reached with limited latency. One of the most important features of LoRaWAN Class B is multicast, which allows a single transmission to be shared by multiple multicast group member end...master thesis 2019
