Development of efficient formulation for the removal of iron sulphide scale in sour production wellsMahmoud, Mohamed (author), Hussein, Ibnelwaleed A. (author), Sultan, Abdullah (author), Saad, Mohammed A. (author), Buijs, W. (author), Vlugt, T.J.H. (author)Iron sulphide scale, which exists in different forms, is common in sour oil and gas production wells. Iron sulphide hard scales are difficult to remove with acids, requiring mechanical intervention or the replacement of the production tubing. An environmentally friendly formulation with a high pH is proposed for the removal of both soft and...journal article 2018

van der El, Kasper (author), Pool, D.M. (author), van Paassen, M.M. (author), Mulder, Max (author)Novel (semi-)automated systems are rapidly being introduced into modern road vehicles, but anticipating possibly critical human-machine interaction issues is difficult, because the human driver’s behavior is as of yet still poorly understood. This paper aims to improve our understanding and models of driver steering behavior on winding roads,...conference paper 2018

Khakzad, N. (author)The performance of fire protection measures plays a key role in the prevention and mitigation of fire escalation (fire domino effect) in process plants. In addition to passive and active safety measures, the intervention of firefighting teams can have a great impact on fire propagation. In the present study, we have demonstrated an application...journal article 2018

Kura, T.M. (author), Fornalik-Wajs, Elzbieta (author), Wajs, Jan (author), Kenjeres, S. (author)Jet impingement still is one of demanding cases regarding computational fluid dynamics, due to its highly turbulent behaviour, with occurrence of turbulent-laminar transition. Even recently developed methods exhibit some drawbacks - RANS based simulations lack accuracy, LES and DNS based ones require too much computational time. Hybrid...journal article 2018

Fu, W. (author), van Paassen, M.M. (author), Mulder, Max (author)Wave-variable transformation is a means to maintain stability of haptic teleoperation in the presence of communication time delays. Its drawback is that it affects haptic perception of remote properties and thereby degrades transparency. This paper studies the effect of wave-variable transformation on human haptic perception. Based on a...conference paper 2018

(author), Bocchini, Luca (author)The roadmap for space exploration foresees longer journeys and further excursions outside low-Earth orbit as well as the establishment of permanent outposts on other celestial bodies, such as the Moon or Mars. The design of spacecrafts and habitats depends heavily on the mission scenario and must consider the radiation protection properties...journal article 2018

Desmond, Cian J. (author), Watson, S.J. (author), Montavon, Christiane (author), Murphy, Jimmy (author)The flow over densely forested terrain under neutral and non-neutral conditions is considered using commercially available computational fluid dynamics (CFD) software. Results are validated against data from a site in Northeastern France. It is shown that the effects of both neutral and stable atmospheric stratifications can be modelled...journal article 2018

We developed a device for directly surveying the luminescent properties of thin-film libraries created through combinatorial gradient sputter deposition. Step-scan recorded excitation-,...journal article 2018

(author), Kouwenhoven, Leo P. (author)Circuit quantum electrodynamics has proven to be a powerful tool to probe mesoscopic effects in hybrid systems and is used in several quantum computing (QC) proposals that require a transmon qubit able to operate in strong magnetic fields. To address this we integrate monolayer graphene Josephson junctions into microwave frequency...journal article 2018

(author)SPECT can be used to image dopamine transporter (DaT) availability in the human striatum, e.g. for diagnosis of Parkinson's disease (PD). As traditional SPECT provides limited resolution and sensitivity, we proposed a full ring focusing multi-pinhole SPECT system (G-SPECT-I (Beekman 2015 Eur. J. Nucl. Med. Mol.

Bismeijer, Tycho (author), Canisius, Sander (author), Wessels, L.F.A. (author)Effective cancer treatment is crucially dependent on the identification of the biological processes that drive a tumor. However, multiple processes may be active simultaneously in a tumor. Clustering is inherently unsuitable to this task as it assigns a tumor to a single cluster. In addition, the wide availability of multiple data types per...journal article 2018
