Verriet, J. (author), van der Sanden, B. (author), van der Veen, G. (author), van Splunter, A. (author), Lousberg, S. (author), Hendriks, M. (author), Basten, T. (author)Product family development facilitates reuse across all phases of systems engineering; in case of model-based systems engineering, this reuse involves the models as well. Introducing a model-based way of working is challenging, especially for product family development. This paper describes a case of introducing a modelbased way of working in...conference paper 2023

Numan, N. (author), Haar, F.T. (author), Cesar, P. (author)Head-mounted displays (HMDs) are an essential display device for the observation of virtual reality (VR) environments. However, HMDs obstruct external capturing methods from recording the user’s upper face. This severely impacts social VR applications, such as teleconferencing, which commonly rely on external RGB-D sensors to capture a...conference paper 2021

Vazquez, A.R. (author), Goos, P. (author), Schoen, E.D. (author)Definitive screening designs permit the study of many quantitative factors in a few runs more than twice the number of factors. In practical applications, researchers often require a design for m quantitative factors, construct a definitive screening design for more than m factors and drop the superfluous columns. This is done when the number of...article 2020

Hannay, J.E. (author), van den Berg, T. (author), Gallant, S. (author), Gupton, K. (author)Modeling and Simulation as a Service (MSaaS) embodies the idea that simulations should be composed quickly for the task at hand from loosely coupled shared components, simulation services, in a cloud-based environment. These simulations are then offered, as composed simulation services, to human and technical consumers. Instrumental to this, is...article 2020

Witte, J.P.M. (author), Zaadnoordijk, W.J. (author), Buyse, J.J. (author)Since the nineteen fifties, groundwater levels in the Netherlands dropped more than as simulated by hydrological models. In the rural sandy part of the Netherlands, the difference amounts to approximately 0.3 m on average. The answer to the question of what or who caused this ‘background decline’ of groundwater tables may have juridical and...article 2019

Klusener, S. (author), Mooij, A.J. (author), Ketema, J. (author), van Wezep, H. (author)When software components are developed iteratively, code frequently evolves in an inductive manner: A unit is created and is then copied and modified many times. Such development often happens when variation points and, hence, proper domain abstractions are initially unclear. As a result, there may be substantial amounts of code duplication, and...conference paper 2018

al Duhaiby, O. (author), Mooij, A.J. (author), van Wezep, H. (author), Groote, J.F. (author)Maintaining legacy software is one of the most common struggles of the software industry, being costly yet essential. We tackle that problem by providing better understanding of software by extracting behavioural models using the model learning technique. The used technique interacts with a running component and extracts abstract models that...conference paper 2018

(author)Situation Awareness (SA) during tele-operation in robot-assisted disaster management has a major impact on the effectiveness and efficiency. Data perceived by the human and robot agents should be processed and shared in such a way that these agents can understand and direct the other agent's behaviors. E.g., for safe and effective tele-operation...conference paper 2017

den Hartog, F.T.H. (author), Daniele, L.M. (author), Roes, J.B.M. (author)About two thirds of the energy consumed in buildings originates household appliances. Nowadays, appliances are often intelligent and networked devices that form complete energy consuming, producing, and managing systems. Reducing energy is therefore a matter of managing and optimizing the energy utilization on a system level. These systems need...conference paper 2015

In such domains, intelligent electronic partners (ePartners) can play a useful role in supporting human-robot teams in their problem solving process whenever a non...conference paper 2015

Daniele, L.M. (author), den Hartog, F.T.H. (author), Roes, J.B.M. (author)Around two thirds of the energy consumed by buildings can be traced back to the residential sectors and thus household appliances. Today, most appliances are highly intelligent and networked devices, in principle being able to form complete energy consuming, producing, and managing systems. Reducing the use of energy has therefore become a...conference paper 2015

van Seijen, H.H. (author), Whiteson, S. (author), Kester, L.J.H.M. (author)This article addresses reinforcement learning problems based on factored Markov decision processes (MDPs) in which the agent must choose among a set of candidate abstractions, each build up from a different combination of state components. We present and evaluate a new approach that can perform effective abstraction selection that is more...article 2014

It is based on a conceptual model and the use of search and ranking algorithms. The conceptual model is based on Abstract State Machine theory. Requirements for dynamic service mediation were derived from a real-world case. The conceptual model and the algorithms are developed...conference paper 2010

Since we are mainly interested in the velocity field upon which an analysis of transport phenomena can be based, we may assume that the flow is quasi steady. A well may be composed of a number of point sinks, therefore...article 1995
