Verhagen, H.J. (author)For this book we have deliberately chosen that the text should follow a more or less logical design procedure for closure dams. It is emphasized that only the construction aspect of stopping the water movement is considered in this book. This means that only the closing operation itself is treated; the transformation of the closing dam into a...lecture notes 2016

Visser, H.G. (author), Santos, Bruno F. (author), Verhagen, C.M.A. (author)This paper describes the development of an optimization-based cooperative planning system for the efficient routing and scheduling of flight formations. This study considers the use of formation flight as a means to reduce the overall fuel consumption of civil aviation in long-haul operations. It elaborates on the operational implementation of...conference paper 2016

Zhao, X. (author), Verhagen, W.J.C. (author), Curran, R. (author)The present study develops a method for the sake of evaluating Disposal and Recycle (D&R) cost in view of the increasing demand in aircraft retirement. Firstly, a process model is extracted. The subordinated cost elements are also identified. Next, the cost aggregations based on the D&R process steps are discussed. Moreover, it proposes...book chapter 2016

Koornneef, H. (author), Verhagen, W.J.C. (author), Curran, R. (author)Currently, task support information in aircraft maintenance is mostly provided using paper-based solutions, which are burdensome, slow and prone to error. Aircraft maintenance documentation contains vast amounts of information irrelevant for the task at hand and even for the simplest tasks multiple documents need to be consulted. Next to these...book chapter 2016

Dhanisetty, V.S.V. (author), Verhagen, W.J.C. (author), Curran, R. (author)This paper details the development of a decision-making model that evaluates the multiple repair levels that a composite structure can undergo, each with its inherent achievable survivability and consequence to operations in terms of availability, costs, and scheduling. The goal of this model is to provide the maintainer an integrated approach...conference paper 2016

Le, H.T. (author), Verhagen, H.J. (author), Vrijling, J.K. (author)Grass covers have been applied as an effective measure for protecting river levees and sea dikes. We conducted experiments to show how roots considerably improve the shear strength of soil on dike slopes. Roots of 1-year-old Bermuda and Carpet grass may increase the total shear strength of up to 20 kPa. Exposed to severe overtopping flow, dike...journal article 2016

Newcamp, Jeffrey (author), Verhagen, W.J.C. (author), Curran, R. (author)Military attack aircraft are susceptible to the harmful effects of widespread fatigue damage caused by cyclic loading of structural components, which leads to airframe retirement. Modern structural health monitoring techniques use a multitude of sensors and high data collection rates. Some legacy airframes, which are most susceptible to fatigue...journal article 2016

Newcamp, Jeffrey (author), Verhagen, W.J.C. (author), Curran, R. (author)Military aircraft fleets are continuing to age despite increased structural integrity concerns and rising maintenance costs. Aircraft are not being replaced or retired in large numbers but are instead having their lives extended beyond their original design service lives. Because aging aircraft cost more to maintain, this additional burden on...conference paper 2016

van Nes, A. (author), López, Manuel (author), de Bonth, L.F.J.M. (author), Verhagen, D.J. (author), Waayer, Simone (author)This contribution describes the tool Social Safe Urban Design (SSUD), seen<br/>together with socio-spatial and linguistic challenges when applying space syntax in the regenerating of problem urban areas. The Space Syntax jargon is technical and needs to be translated into a language understandable and acceptable to stakeholders who are...book chapter 2016

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

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

(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

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

Verhagen, C.M.A. (author)A model has been developed to demonstrate the value of a decentralized approach to formation flight routing. In the considered scenario, formation flight is an in-flight option. While centralized approaches are well covered in the literature, anticipating the use of formation flight before take-off, decentralized approaches have received less...master thesis 2015
