Van den Beemt, Antoine (author), MacLeod, Miles (author), Van der Veen, Jan (author), Van de Ven, Anne (author), van Baalen, Sophie (author), Klaassen, R.G. (author), Boon, Mieke (author)Background: Societal challenges that call for a new type of engineer suggest the need for the implementation of interdisciplinary engineering education (IEE). The aim of IEE is to train engineering students to bring together expertise from different disciplines in a single context. This review synthesizes IEE research with a focus on...review 2020

Mouri Sardarabadi, A. (author), Leshem, A. (author), Van der Veen, A.J. (author)Aims. Image formation for radio astronomy can be defined as estimating the spatial intensity distribution of celestial sources throughout the sky, given an array of antennas. One of the challenges with image formation is that the problem becomes ill-posed as the number of pixels becomes large. The introduction of constraints that incorporate a...journal article 2016

Schäfer, P. (author), Van der Veen, M.A. (author), Domke, K.F. (author)To employ the full potential of electrochemical (ec) synthesis to grow metal–organic frameworks (MOFs) in more complex organizations at the mesoscale, it is vital to understand the underlying crystallization reaction pathway. For the MOF most typically grown electrochemically, CuBTC, we systematically investigated the role of oxygen species in...journal article 2016

Second harmonic generation microscopy reveals hidden polar organization in fluoride doped MIL-53(Fe)Markey, K. (author), Putzeys, T. (author), Horcajada, P. (author), Devic, T. (author), Guillou, N. (author), Wübbenhorst, M. (author), Van Cleuvenbergen, S. (author), Verbiest, T. (author), De Vos, D.E. (author), Van der Veen, M.A. (author)Polar metal–organic frameworks have potential applications as functional non-linear optical, piezoelectric, pyroelectric and ferroelectric materials. Using second harmonic generation microscopy we found that fluoride doping of the microporous iron(III) terephthalate MOF MIL-53(Fe) induces a polar organization in its structure, which was not...journal article 2016

(author)The past decade has seen the advent of various radio astronomy arrays, particularly for low-frequency observations below 100 MHz. These developments have been primarily driven by interesting and fundamental scientific questions, such as studying the dark ages and epoch of re-ionization, by detecting the highly red-shifted 21 cm line emission....journal article 2015

Sarijari, M.A.B. (author), Abdullah, M.S. (author), Janssen, G.J.M. (author), Van der Veen, A.J. (author)The growing number of wireless devices for in-house use is causing a more intense use of the spectrum to satisfy the required quality-of-service such as throughput. This has contributed to spectrum scarcity and interference problems particularly in home area networks (HAN). Cognitive radio (CR) has been recognized as one of the most important...journal article 2015

(author)At this point in time, 3D-printing techniques in general, but especially applied for the building industry, still are in a phase of early experiments. One of the experimental attempts is to print a full-scale, three-story high, house in Amsterdam, using an up scaled version of a FDM-printer that is able to print blocks of 1.8 x 1.8 x 3.0 meters...conference paper 2015

Ensink, S.W.H. (author), Van der Veen, C. (author), De Boer, A. (author)Experimental results of four shear tests on two large prestressed concrete beams are compared to nonlinear analysis and design code calculations. The beams have a length of 12 m and a depth of 1.3 m and are reinforced with stirrups and pre-tensioning. The four tests consist of a single point load at a distance of 2.7d from the support. A priori...conference paper 2015

Lantsoght, E.O.L. (author), Van der Veen, C. (author), De Boer, A. (author)Slabs subjected to concentrated loads close to supports, as occurring for truck loads on slab bridges, are less studied than beams in shear or slab-column connections in punching. To predict the shear capacity for this case, the Bond Model for concentric punching shear was studied initially. Modifications to this model resulted in the Modified...conference paper 2015

Van Ormondt, D. (author), De Beer, R. (author), Van der Veen, J.W.C. (author), Sima, D.M. (author), Graveron-Demilly, D. (author)MRI-scanners enable non-invasive, in vivo quantitation of metabolites in, e.g., the brain of a patient. Among other things, this requires adequate estimation of the unknown temporal decay function of the complex-valued signal emanating from the metabolites. We propose a method to render a current decay estimator more simple, accurate, and robust...conference paper 2015

Lantsoght, E.O.L. (author), Van der Veen, C. (author), De Boer, A. (author)The shear problem is typically studied by testing small, heavily reinforced, slender beams subjected to concentrated loads, resulting in a beam shear failure, or by testing slab-column connections, resulting in a punching shear failure. Slabs subjected to concentrated loads close to supports, as occurring when truck loads are placed on slab...conference paper 2014

Lantsoght, E.O.L. (author), Van der Veen, C. (author), De Boer, A. (author)For an initial design or assessment of a reinforced concrete solid slab bridge, spreadsheet-based or hand calculations are typically used. The shear stress is compared to the shear capacity as prescribed by the code. The distributed loads result in a uniform shear stress at the support. Concentrated loads are less straightforward to take into...conference paper 2014

Nasalevich, M.A. (author), Van der Veen, M. (author), Kapteijn, F. (author), Gascon, J. (author)The use of metal organic frameworks (MOFs) as heterogeneous photocatalysts is critically reviewed. First we revisit the general assumption of MOFs behaving truly as semiconductors, demonstrating that such semiconducting behaviour only occurs in a very limited subset of materials. Further, the main approaches for efficient light harvesting and...journal article 2014

Amir, S. (author), Van der Veen, C. (author), Walraven, J.C. (author), De Boer, A. (author)In the Netherlands, most of the bridges were built more than 50 years ago and it is essential for designers to find out if these bridges are safe for modern traffic especially in shear since that was not considered in design recommendations before 1976. Detailed experiments have been carried out in the laboratory to investigate punching shear...conference paper 2014

(author), Van der Veen, M.A. (author)Regioregular poly(3-hexylthiophene)s with chain lengths varying from 5 to 100 monomers are synthesized. Poly(3-hexylthiophene)s show in solution an unexpectedly significant second-order nonlinear optical response. The increase in transition dipole moment upon oligomerisation causes the significant second-order nonlinear optical response.journal article 2014
