Groenendijk, Laura (author), Rezaei, J. (author), Correia, Gonçalo (author)The quality of a transit node is determined by the experience of travellers. However, the reference model for classifying the quality of a transit node, the so-called Node-Place model, does not consider this important dimension (experience). In this paper, we propose a method to add quality from a traveller's perspective to the Node-Place (NP...journal article 2018

Aravind, M.A. (author), Saikumar, N. (author), Dinesh, N. S. (author), Rajanna, K. (author)Experience mapping based predictive controller (EMPC) is a recently developed controller based on the concepts of Human Motor Control. It has been demonstrated to out-perform other classical controllers like proportional-derivative (PD), model reference based adaptive controller (MRAC), linear quadratic regulator (LQR) and the linear...journal article 2018

Dash, A. (author), Elsinga, G.E. (author)While laboratory experiments, numerical simulations as well as field tests have underlined the influence of noise barriers in dispersing vehicular emissions and reducing downwind peak concentrations, these pollutants still remain in the atmosphere. Artificial pollutant sinks (for example, particle capturing or toxic gas treating devices)...journal article 2018

(author), Geiker, Mette (author), Brekke, Dan Evert (author), Kanstad, Terje (author)This paper theoretically and experimentally investigates the semi-empirical formulas recommended by Eurocode 2 (EC2), fib Model Code 2010 (MC2010), and Eurocode 2 with the German National Annex (DIN) for calculating crack widths in reinforced concrete. It is shown that the formulas can be derived from the principles for the idealized behavior...journal article 2018

Camere, S. (author), Schifferstein, Hendrik N.J. (author), Bordegoni, Monica (author)Designing for pleasurable and engaging product experiences requires an understanding of how users will experience the product, sometimes at a very abstract level. This focus on user experiences, rather than on the formal qualities of the product, might cause difficulties for designers in the materialization of design ideas. Designers need to...journal article 2018

Frederik, J.A. (author), Kröger, Lars (author), Gülker, Gerd (author), van Wingerden, J.W. (author)A commonly applied method to reduce the cost of wind energy, is alleviating the periodic loads on turbine blades using Individual Pitch Control (IPC). In this paper, a data-driven IPC methodology called Subspace Predictive Repetitive Control (SPRC) is employed. The effectiveness of SPRC will be demonstrated on a scaled 2-bladed wind turbine....journal article 2018

Mahajan, V.V. (author), Nijssen, Tim M.J. (author), Kuipers, J.R. (author), Padding, J.T. (author)Fluidised beds are used in a variety of processes because of their favourable mass and heat transfer characteristics. In this and many other processes, non-spherical particles are commonplace, which can drastically affect the fluidisation behaviour. In this study, we use numerical models to study non-spherical fluidisation behaviour in detail...journal article 2018

van Essen, Mariska (author), Thomas, Tom (author), van Berkum, Eric (author), Chorus, C.G. (author)This study examines to what extent travel information can be used to direct travelers to system-optimal routes that may be sub-optimal for them personally, but contribute to network efficiency. This is done by empirically examining determinants of travelers’ compliance with social routing advice. To that end, we conducted both a stated choice...journal article 2018

(author), Lehnhoff, Sebastian (author), Palensky, P. (author)The complex and often safety-critical nature of cyber-physical energy systems makes validation a key challenge in facilitating the energy transition, especially when it comes to the testing on system level. Reliable and reproducible validation experiments can be guided by the concept of design of experiments, which is, however, so far not...conference paper 2018

Frontline police officers are working on the streets and need the right information at the right time. Mobile technology can provide location-based information and could be of great assistance to them. We developed a mobile location-based real-time notification system and conducted...journal article 2018

Le, T.B. (author), Crosato, A. (author), Uijttewaal, W.S.J. (author)Rivers have been trained for centuries by channel narrowing and straightening. This caused important damages to their ecosystems, particularly around the bank areas. We analyse here the possibility to train rivers in a new way by subdividing their channel in main and ecological channel with a longitudinal training wall. The effectiveness of...journal article 2018

Ochoa, J. Jorge (author), Tan, Yongtao (author), Qian, QK (author), Shen, Liyin (author), Moreno, Eduardo López (author)Attempts for implementing sustainable urbanization have been reported and documented around the world. These efforts have led to a vast number of exemplary sustainable urbanization practices, classified as best practices. Best practices contain valuable information in the form of experiences, and learning from them represents an opportunity...journal article 2018

de Bruin, T.D. (author), Kober, J. (author), Tuyls, K.P. (author), Babuska, R. (author)Experience replay is a technique that allows off-policy reinforcement-learning methods to reuse past experiences. The stability and speed of convergence of reinforcement learning, as well as the eventual performance of the learned policy, are strongly dependent on the experiences being replayed. Which experiences are replayed depends on two...journal article 2018

(author)Adaptive Cruise Control (ACC) and automated vehicles can contribute to reduce traffic congestion and accidents. Recently, an on-road study has shown that drivers may prefer to deactivate full-range ACC when closing in on a slower leader and to overrule it by pressing the gas pedal a few seconds after the activation of the system. Notwithstanding...journal article 2018
