Dong, J. (author), Van Driel, W. (author), Zhnag, G. (author)This paper describes a new design concept of automatically diagnosing and compensating LED degradations in distributed solid state lighting (SSL) systems. A failed LED may significantly reduce the overall illumination level, and destroy the uniform illumination distribution achieved by a nominal system. To our knowledge, an automatic scheme to...journal article 2011

Nijhuis, S. (author), Van Lammeren, R. (author), Van der Hoeven, F. (author)Exploring the Visual Landscape is about the combination of landscape research and planning, visual perception and Geographic Information Science. It showcases possible ways of getting a grip on themes like: landscape openness, cluttering of the rural landscape, high-rise buildings in relation to cityscape, historic landscapes and motorway...book 2011

Wever, R. (author), Vogtländer, J. (author)The classical sustainability perspective on packaging is to reduce the environmental impact or eco burden of the packaging, using life cycle assessment to evaluate different design alternatives. Simultaneously, the classical marketing perspective on packaging is to generate value through differentiation, for instance, by providing additional...journal article 2012

Bier, H.H. (author)Distributed, networked, electronically tagged, interactive devices are increasingly incorporated into the physical envi-ronment blurring progressively the boundary between physical and virtual space. This changing relationship between physical and virtual implies not only a change in the operation and use of buildings but also a change in their...journal article 2012

Van der Put, T.A.C.M. (author)A derivation is given of simplified, exact stability design rules according to limit analysis, applied to timber beam-columns. These rules are lacking but are necessary to be able to provide real and calculable reliability as is required according to European pacts and laws. Necessary therefore are the obtained exact combined bi-axial bending,...journal article 2013

Mata Pavia, J. (author), Wolf, M. (author), Charbon, E. (author)Single-photon avalanche diode (SPAD) imagers typically have a relatively low fil factor, i.e. a low proportion of the pixel’s surface is light sensitive, due to in-pixel circuitry. We present a microlens array fabricated on a 128x128 single-photon avalanche diode (SPAD) imager to enhance its sensitivity. The benefit and limitations of these...journal article 2014

Dilner, D. (author), Lu, Q. (author), Mao, H. (author), Xu, W. (author), Van der Zwaag, S. (author), Selleby, M. (author)This paper demonstrates the use of a new model consisting of a genetic algorithm in combination with thermodynamic calculations and analytical process models to minimize the processing time during a vacuum degassing treatment of liquid steel. The model sets multiple simultaneous targets for final S, N, O, Si and Al levels and uses the total slag...journal article 2014

Loussos, P. (author), Konstantinou, T. (author), Van den Dobbelsteen, A.A.J.F. (author), Bokel, R. (author)The existing building stock has been in the focus of European Union policies for energy savings. Nevertheless, energy certification schemes refer mostly to operational energy and usually do not consider aspects related to the life cycle of the building. To look at the overall energy cost during the lifespan of a building, the energy used to...journal article 2015

Konstantinou, T. (author)Over the next decade investment in building energy savings needs to increase, together with the rate and depth of renovations, to achieve the required reduction in buildingrelated CO2 emissions. Although the need to improve residential buildings has been identified, guidelines come as general suggestions that fail to address the diversity of...journal article 2015

Schifferstein, Hendrik N.J. (author)Even though designers are specifically trained to create and build new products, their contribution to innovation in the food industry is relatively small. The industry seems unfamiliar with the ways in which designers operate and may be unaware of the added value they may provide. Therefore, this article identifies the potential roles that...journal article 2016

Scholten, D.J. (author), Kunneke, R.W. (author)Energy infrastructures are increasingly perceived as complex, adaptive socio-technical systems. Their design has not kept up; it is still fragmented between an engineering and economic dimension. While economists focus on a market design that addresses potential market failures and imperfections, opportunistic behavior, and social objectives,...journal article 2016

A Multi-Objective Optimization Framework for Offshore Wind Farm Layouts and Electric InfrastructuresFragoso Rodrigues, S.M. (author), Restrepo, C. (author), Katsouris, G. (author), Teixeira Pinto, R. (author), Soleimanzadeh, M. (author), Bosman, P. (author), Bauer, P. (author)Current offshore wind farms (OWFs) design processes are based on a sequential approach which does not guarantee system optimality because it oversimplifies the problem by discarding important interdependencies between design aspects. This article presents a framework to integrate, automate and optimize the design of OWF layouts and the...journal article 2016

Echevarria Icaza, L. (author), van den Dobbelsteen, A.A.J.F. (author), van der Hoeven, F.D. (author)The world is increasingly concerned with sustainability issues. Climate change is not the least of these concerns. The complexity of these issues is such that data and information management form an important means of making the right decisions. Nowadays, however, the sheer quantity of data is overwhelming; large quantities of data demand...journal article 2016

Zhang, X.Y. (author), Fang, G (author), Zhou, J. (author)Additive manufacturing (AM), nowadays commonly known as 3D printing, is a revolutionary materials processing technology, particularly suitable for the production of low-volume parts with high shape complexities and often with multiple functions. As such, it holds great promise for the fabrication of patient-specific implants. In recent years,...journal article 2017

(author)The goal of this study was to determine the preferred handle design for two degrees of freedom steerable arthroscopic cutter by performing a two-step development approach. The expected usefulness and usability of control components of three entirely different handles were defined by an on-line survey with 101 students and the actual control...journal article 2017

Raji, B. (author), Tenpierik, M.J. (author), van den Dobbelsteen, A.A.J.F. (author)Decisions made at early stages of the design are of the utmost importance for the energy-efficiency of buildings. Wrong decisions and design failures related to a building’s general layout, shape, façade transparency or orientation can increase the operational energy tremendously. These failures can be avoided in advance through simple changes...journal article 2017

Santoni De Sio, F. (author), van den Hoven, M.J. (author)Debates on lethal autonomous weapon systems have proliferated in the past 5 years. Ethical concerns have been voiced about a possible raise in the number of wrongs and crimes in military operations and about the creation of a “responsibility gap” for harms caused by these systems. To address these concerns, the principle of “meaningful human...journal article 2018
