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...

Experimental evaluation of load transfer efficiency of non-dowelled concrete pavements

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...

Orientation Comes First: Becoming Aware of Spatial Disorientation Interferes with Cognitive Performance

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)...

Review: Horizontal, directionally drilled and radial collector wells: Pozos horizontales y colectores radiales de perforación direccional

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...

Managing bias and unfairness in data for decision support: a survey of machine learning and data engineering approaches to identify and mitigate bias and unfairness within data management and analytics systems

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...

Determination of fracture energy of early age concrete through a uniaxial tensile test on an un-notched specimen

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....

Laboratory characterization of the load transfer-crack width relation for innovative short concrete slabs pavements

Pradena, M.A. (author), Houben, L.J.M. (author), César, Andrés (author)

Aggregate interlock is the dominant load transfer mechanism in non-dowelled Jointed Plain Concrete Pavements, as the innovative short concrete slabs. Although the Load Transfer Efficiency of this pavement innovation is based on that mechanism, the structural design methods do not relate the Load Transfer Efficiency by aggregate interlock with...

Fracture-Induced Permeability in Whitby Mudstone

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...

Complex event processing on real-time video streams

Li, Z. (author), Katsifodimos, A (author), Bozzon, A. (author), Houben, G.J.P.M. (author)

Cameras are ubiquitous nowadays and video analytic systems have been widely used in surveillance, traffic control, business intelligence and autonomous driving. Some applications, e.g., detecting road congestion in traffic monitoring, require continuous and timely reporting of complex patterns. However, conventional complex event processing ...

Supporting Self-Regulated Learning in Online Learning Environments and MOOCs: A Systematic Review

Wong, Jacqueline (author), Baars, Martine (author), Davis, D.J. (author), van der Zee, M.T.A. (author), Houben, G.J.P.M. (author), Paas, Fred (author)

Massive Open Online Courses (MOOCs) allow learning to take place anytime and anywhere with little external monitoring by teachers. Characteristically, highly diverse groups of learners enrolled in MOOCs are required to make decisions related to their own learning activities to achieve academic success. Therefore, it is considered important to...

Approaches for Dialog Management in Conversational Agents

Harms, Jan-Gerrit (author), Kucherbaev, P. (author), Bozzon, A. (author), Houben, G.J.P.M. (author)

Dialog agents, like digital assistants and automated chat interfaces (e.g., chatbots), are becoming more and more popular as users adapt to conversing with their devices as they do with humans. In this paper, we present approaches and available tools for dialog management (DM), a component of dialog agents that handles dialog context and...

Joint faulting behaviour of innovative short concrete slabs

Pradena, Mauricio (author), Houben, L.J.M. (author)

Pavements are one of the largest assets of a city and their functional condition (ride quality) is priority for their clients. In jointed plain concrete pavements (JPCPs), the presence of joint faulting (JF) reduces the ride quality. Today, short slabs are available as a cost-effective JPCP innovation. The objective of this paper is to analyse...

Potential permeability enhancement in Early Jurassic shales due to their swelling and shrinkage behavior

Houben, M. E. (author), Barnhoorn, A. (author), Peach, C. J. (author), Drury, M. R. (author)

The presence of water in mudrocks has a largely negative impact on production of gas stored in these rocks, due to the fact that water causes swelling of the rock. Removing the water from the mudrock could potentially shrink the rock and increase the overall permeability of the rock. Investigation of the swelling/shrinkage behaviour of the...

Modelling the effect of plastic sheet curing on early age temperature development in concrete pavement

Ren, Dongya (author), Houben, L.J.M. (author)

Prediction of the temperature development at an early age is a good starting point to assess the development of the restrained thermal stress and thermal cracking in rigid pavements. This paper presents a numerical early age concrete pavement temperature prediction model. It enables to evaluate the effect of various paving conditions, such as...

Experimental identification of the transition from elasticity to inelasticity from ultrasonic attenuation analyses

Barnhoorn, A. (author), Verheij, Jeroen (author), Frehner, Marcel (author), Zhubayev, A. (author), Houben, Maartje (author)

The transition from recoverable elastic to permanent inelastic deformation is marked by the onset of fracturing in the brittle field. Detection of this transition in materials is crucial to predict imminent failure/fracturing. We have<br/>used an ultrasonic pulse transmission method to record the change in waveform across this transition during...

Human Aided Bots

Kucherbaev, P. (author), Bozzon, A. (author), Houben, G.J.P.M. (author)

A chatbot is an example of a text-based conversational agent. While natural language understanding and machine learning techniques advance rapidly, current fully automated chatbots still struggle to serve their users well. Human intelligence, brought by crowd workers, freelancers or even full-time employees can be embodied in the chatbot logic...

Evaluating Crowdworkers as a Proxy for Online Learners in Video-Based Learning Contexts

Davis, D.J. (author), Hauff, C. (author), Houben, G.J.P.M. (author)

Crowdsourcing has emerged as an effective method of scaling-up tasks previously reserved for a small set of experts. Accordingly, researchers in the large-scale online learning space have begun to employ crowdworkers to conduct research about large-scale, open online learning. We here report results from a crowdsourcing study (N=135) to evaluate...
