Houben, A.L. (author), Soleymani Shishvan, M. (author)Mineral resource modelling (MRM) requires enough geological information to define the geological model. The success of a mining project is supported by the accuracy of this model and its interpretation. Major failures can occur as a result of an incorrect degree of uncertainty quantification in the geological/geometallurgical models. There are...abstract 2023

Houben, Georg J. (author), Collins, Sarah (author), Bakker, M. (author), Daffner, Thomas (author), Triller, Falk (author), Kacimov, Anvar (author)Horizontal wells play an often overlooked role in hydrogeology and aquifer remediation but can be an interesting option for many applications. This study reviews the constructional and hydraulic aspects that distinguish them from vertical wells. Flow patterns towards them are much more complicated than those for vertical wells, which makes their...journal article 2022

(author)How can humans remain in control of artificial intelligence (AI)-based systems designed to perform tasks autonomously? Such systems are increasingly ubiquitous, creating benefits - but also undesirable situations where moral responsibility for their actions cannot be properly attributed to any particular person or group. The concept of...journal article 2022

Pradena, Mauricio (author), Houben, L.J.M. (author), César, Andrés (author)Generally, joint performance in concrete pavements is evaluated in laboratory by applying dynamic loads that require large scale experimental setups. In order to propose a simplified laboratory test, a comprehensive literary review of the fundamentals of load transfer at joints is made, and the load transfer efficiency obtained via a reduced...journal article 2022

Landman, H.M. (author), Kalogeras, Dimitrios (author), Houben, Mark (author), Groen, Eric L. (author)Background: Previous research has shown that experiencing motion stimuli negatively impacts cognitive performance. Objective: In the current study, we investigate whether this impact relates to Type-II spatial disorientation (SD), to motion stimulus magnitude, or to an interaction of these factors. Method: Stimuli for participants (n = 23)...journal article 2022

Balayn, A.M.A. (author), Lofi, C. (author), Houben, G.J.P.M. (author)The increasing use of data-driven decision support systems in industry and governments is accompanied by the discovery of a plethora of bias and unfairness issues in the outputs of these systems. Multiple computer science communities, and especially machine learning, have started to tackle this problem, often developing algorithmic solutions to...journal article 2021

Ionescu, A. (author), Katsifodimos, A (author), Houben, G.J.P.M. (author)As data is produced at an unprecedented rate, the need and ex- pectation to make it easily available for the end-users is growing. Dataset Discovery has become an important subject in the data management community, as it represents the means of providing the data to the user and fulfilling an information need. Since the end-user is the one that...conference paper 2021

Siachamis, G. (author), Houben, G.J.P.M. (author), van Deursen, A. (author), Katsifodimos, A (author)Data Integration has been a long-standing and challenging problem for enterprises and researchers. Data residing in multiple heterogeneous sources must be integrated and prepared such that the valuable information that it carries, can be extracted and analysed. However, the volume and the velocity of the produced data in addition to the modern...conference paper 2021

van Alphen, G.A. (author), Qiu, S. (author), Bozzon, A. (author), Houben, G.J.P.M. (author)In online crowd mapping, crowd workers recruited through crowdsourcing marketplaces collect geographic data. Compared to traditional mapping methods, where workers physically explore the area, the benefit of using online crowd mapping is the potential to be cost-effective and time-efficient. Previous studies have focused on mapping urban objects...conference paper 2020

Qiu, S. (author), Gadiraju, Ujwal (author), Bozzon, A. (author), Houben, G.J.P.M. (author)The trend of remote work leads to the prosperity of crowdsourcing marketplaces. In crowdsourcing marketplaces, online workers can select their preferable tasks and then complete them to get paid, while requesters design and publish tasks to acquire their desirable data. The standard user interface of the crowdsourcing task is the web page,...conference paper 2020

Ren, D. (author), Houben, L.J.M. (author)Unlike the notched specimens for conventional concrete fracture tests, this paper introduces a deformation-controlled uniaxial tensile test on an un-notched specimen. The surface of the dog bone-shaped specimen is a second order parabolic curve, and the gradual change in the specimen shape does not lead to extreme stress concentrations....journal article 2020

Houben, Maartje E. (author), van Eeden, Jasmijn C.M. (author), Barnhoorn, A. (author), Hangx, Suzanne J.T. (author)Shale host rock and containment potential are largely determined by the connected pore network in the rock, and the connection between the pore network and the naturally present or mechanically induced fracture network together determines the total bulk permeability. Pore connectivity in shales is poorly understood because most of the...journal article 2020
