Burhani, Shahir (author), Verhagen, W.J.C. (author), Curran, R. (author)Aircraft and aircraft components are redelivered to the next operator or owner during the phase-out process. During this process the operator is required by law and contract requirements to show compliance with maintenance procedures. At KLM E&M the phase-out documentation process is under increasing scrutiny as the number of aircraft...conference paper 2016

Salauddin, M. (author), Broere, A. (author), Van der Meer, J.W. (author), Verhagen, H.J. (author), Bijl, E. (author)A new and symmetrical single layer armour unit, the crablock, has been designed in the UAE. One breakwater was reconstructed with crablock, but very limited testing had been performed. Just to become more acquainted with this new unit, pre-competitive research at a university has been performed, which is the subject of this paper. Being a new...conference paper 2015

Van den Bos, J.P. (author), Verhagen, H.J. (author), Kuiper, C. (author)This paper presents the results of a systematic validation of numerical simulation of reflection and transmission of rubble-mound breakwater structures. The aim of the study is to provide a body of validation measurements for increasingly complex situations, starting simple and building up the comlexity in terms of breawater geometry, wave...conference paper 2015

Zhao, X. (author), Verhagen, W.J.C. (author), Curan, R. (author)n an integrated aircraft design and analysis practice, Life Cycle Cost (LCC) is essential for decision making. The LCC of an aircraft is ordinarily partially estimated by emphasizing a specific cost type. However, an overview of the LCC including design and development cost, production cost, operating cost and disposal cost is not provided. This...book chapter 2015

Crum, S. (author), Van der Hoeven, M.L.E.B. (author), Krouwel, L.P.H.C. (author), Verhagen, H.J. (author)Quantifying the penetration depth of a dragging anchor on a horizontal layer of rockfill provides the possibility to optimize the layer thickness of rockfill layers with a protective function. Current research on this subject is limited and is often aimed at anchor capacities in sand and clay. Penetration behaviour in rockfill is mainly...conference paper 2015

López Royo, M. (author), Burgmeijer, M. (author), Verhagen, H.J. (author)Sectoral professionals, like coastal engineers, need to know how to cooperate in a multi-disciplinary environment, as well as how to present substantial information to (political) decision makers. In order to train (coastal engineering) students in this matter, Unesco-IHE and TU Delft have in their curriculum an Integrated Coastal Zone...conference paper 2015

Verpoorten, S.P.K. (author), Ockeloen, W.J. (author), Verhagen, H.J. (author)Since 1977 dedicated studies are made to the stability of rubble mound break-water toes under wave attack. A large number of stability methods is available, but prediction accuracy is low and validity ranges are too small for use in prac-tice. In this research the decoupled model approach is used to evaluate predic-tion capacity of existing toe...conference paper 2015

Mulder, B. (author), La Rocca, G. (author), Schut, J. (author), Verhagen, W.J.C. (author)A short lead time of the Product Development Process (PDP) is an important competitive advantage for companies. Design automation solutions provide a means to reduce the lead time and improve quality, but their development requires some investment. Before a company can commit to the development of an automation initiative, it requires an...conference paper 2015

(author), Linn, S.C. (author)Breast cancers with BRCA1 germline mutation have a characteristic DNA copy number (CN) pattern. We developed a test that assigns CN profiles to be ‘BRCA1-like’ or ‘non-BRCA1-like’, which refers to resembling a BRCA1-mutated tumor or resembling a tumor without a BRCA1 mutation, respectively. Approximately one third of the BRCA1-like breast...journal article 2015

Stjepandic, J (author), Verhagen, W.J.C. (author), Wognum, Nel (author)CE has been used for more than two decades now. Despite many successes and advantages, there are still many challenges to be addressed. These challenges are both technical and organisational. In the paper we will address the current challenges of CE. Many challenges are related to the exchange of data and...conference paper 2015

Trung, L.H. (author), Van der Meer, J.W. (author), Verhagen, H.J. (author)Little is known about the strength of the land-side slopes of the Vietnamese sea dikes under overtopping attack. Some grass-covered slopes were tested by a wave overtopping simulator. The paper describes the simulator and presents the test results. The tested grass covers could withstand overtopping rates varying from 20 l/s to 100 l/s per meter...journal article 2014

Verhagen, H.J. (author)In physical model tests there is often a need of preventing stones from moving. This can be achieved by gluing the stones. Applying PBA (Polyurethane Bonded Agregate, e.g. Elastocoast) guarantees no moving stones, a normal permeability and a transportable model.conference paper 2014

Hai, T.L. (author), Verhagen, H.J. (author)Many dike failures have been ignited by damage due to erosion on the landward slopes. This paper investigates how grass covered slopes perform when being attacked by overtopping flow during storm surges. Based on observations during a number of simulator tests, damage is classified into three types 'head-cut', 'roll-up' and 'collapse' depending...conference paper 2014
