Salameh, S. (author), van der Veen, M.A. (author), Kappl, Michael (author), van Ommen, J.R. (author)In this work we present a comprehensive experimental study to determine the contact forces between individual metal oxide nanoparticles in the gas-phase using atomic force microscopy. In addition, we determined the amount of physisorbed water for each type of particle surface. By comparing our results with mathematical models of the...journal article 2017

Guerra Santin, O. (author), Boess, S.U. (author), Konstantinou, T. (author), Romero Herrera, N.A. (author), Klein, T. (author), Silvester, S. (author)Large differences between the expected and actual energy consumption have been found in energy efficient dwellings. Research has shown that these differences are partially caused by occupant behaviour. The financing and payback periods of low carbon technologies are often uncertain because of the impact of the occupants on building...journal article 2017

Baldi, S. (author), Le, Q.T. (author), Holub, O. (author), Endel, P. (author)Condensing boilers achieve higher efficiency than traditional boilers by using waste heat in flue gases to preheat cold return water entering the boiler. Water vapor produced during combustion is condensed into liquid form, thus recovering its latent heat of vaporization, leading to around 10–12% increased efficiency. Many countries have...journal article 2017

Bui, T.H. (author), Morana, B. (author), Akhnoukh, A.B. (author), Chu Duc, Trinh (author), Sarro, Pasqualina M (author)A surface-acoustic-mode aluminum nitride (AlN) transducer is utilized to determine the type of liquid dropped on the propagation path. It is based on tracking the shrinking droplet radius and observing stagnant liquid molecules during and after the liquid evaporation process. The device configuration is suitable to test small amounts of...journal article 2017

Ghosh, D. (author), Baldi, S. (author)Several classes of multi-model adaptive control schemes have been proposed in literature: instead of one single parameter-varying controller, in this adaptive methodology multiple fixed-parameter controllers for different operating regimes (i.e. different models) are utilised. Despite advances in multi-model adaptive control theory, the question...journal article 2017

Kalikmanov, V.I. (author), Hagmeijer, R. (author), Venner, C.H. (author)The solid–vapor interfacial free energy γsv plays an important role in a number of physical phenomena, such as adsorption, wetting, and adhesion. We propose a closed form expression for the orientation averaged value of this quantity using a statistical mechanical perturbation approach developed in the theory of liquids. Calculations of γsv...journal article 2017

van Riessen, B. (author), Negenborn, R.R. (author), Dekker, Rommert (author)The intermodal hinterland transportation of maritime containers is under pressure from port authorities and shippers to achieve a more integrated, efficient network operation. Current optimisation methods in literature yield limited results in practice, though, as the transportation product structure limits the flexibility to optimise network...journal article 2017

Hjortnaes, T. (author), Wiegmans, B. (author), Negenborn, R.R. (author), Zuidwijk, R.A. (author), Klijnhout, R. (author)Shipping companies are striving to optimize their empty container repositioning strategies which also contribute to reduced congestion and environmental improvements. In this paper we propose a multi-commodity model that makes an explicit distinction between flows of non-damaged containers, on the one hand, and flows of damaged containers, on...journal article 2017

Lenaerts, JTM (author), Van Tricht, Kristof (author), Lhermitte, S.L.M. (author), L'Ecuyer, T.S. (author)Clouds play a pivotal role in the surface energy budget of the polar regions. Here we use two largely independent data sets of cloud and surface downwelling radiation observations derived by satellite remote sensing (2007–2010) to evaluate simulated clouds and radiation over both polar ice sheets and oceans in state-of-the-art atmospheric...journal article 2017

(author), Zheng, Lanbo (author)The current weaknesses of the conventional intermodal freight transportation system have led to the development of the synchromodal freight transportation concept introduced and piloted in the Netherlands. The innovative concept has the advantage of adding flexibility, cost reduction, and sustainability among other things, into the freight...journal article 2017

Awai, L. (author), Franz, M. (author), Easthope, C. S. (author), Vallery, H. (author), Curt, A (author), Bolliger, M (author)Background: Body weight supported locomotor training was shown to improve walking function in neurological patients and is often performed on a treadmill. However, walking on a treadmill does not mimic natural walking for several reasons: absent self-initiation, less active retraction of leg required and altered afferent input. The...journal article 2017

However, the robustness of business models (BM) is seldom tested vis-à-vis the fast and unpredictable changes in digital technologies, regulation and markets. The evaluation of the robustness of a BM raises several...journal article 2017

(author), Mol, J.M.C. (author)Copper foil was anodized in 1 M KOH at potentials ranging from −400 to −100 mV vs. Ag|AgCl electrode. Cyclic voltammetry showed a distinct peak with a maximum at around −150 mV. For anodizing at −100 and −200 mV, nanowires with diameters of ca. 19 and 24 nm respectively were found to be grown. Moreover, photoluminescence and X-ray diffraction...journal article 2017

Plooij, M.C. (author), Wolfslag, W.J. (author), Wisse, M. (author)This paper identifies the class of actuators called clutched elastic actuators (CEAs). CEAs use clutches to control the energy flow into springs. CEAs in exoskeletons, prostheses, legged robots, and robotic arms have shown the ability to reduce the energy consumption and motor requirements, such as peak torque and peak power. Because of those...journal article 2017
