Cunningham, S.W. (author), Kwakkel, J.H. (author)This paper discusses capabilities for a systematic overview of world science delivered from the use of new output indicators of science and technology. The data may be usefully structured using a complex network perspective on national publication and international collaboration. This paper uses a random sample of publication data from 2009 to...conference paper 2011

Kavian, M. (author), Slob, E.C. (author), Mulder, W.A. (author)We measured the electric parameters for four different configurations of unconsolidated homogeneous and layered sands as a function of frequency, water saturation, and salinity under fluid flow conditions. Our objective is to determine if the effect of heterogeneities at scales much smaller than the skin depth can be captured by introducing...journal article 2011

Van Bortel, G. (author)There has been a growing understanding in the Netherlands and in the UK that sustained area based interventions are needed to address the multiple forms of deprivation concentrated in some neighbourhoods. Not-for-profit housing associations contribute to the regeneration of these neighbourhoods, each within the context of their national housing...conference paper 2011

Hobma, F. (author)This paper aims at answering the question: How can we explain the evidently unstoppable growth of regulations for planning and building? The answer to this question is of relevance, since we have been (and still are) confronted with the negative consequences of an overly complex and comprehensive legal framework for planning and building. This...conference paper 2011

Sackey, E. (author), Tuuli, M.M. (author), Dainty, A. (author)The complex and dynamic nature of project environments presents both opportunities and challenges for the empowerment of individuals and teams. Yet, empowerment is a complex concept in its own right, taking on multiple forms across people, is contextually embedded and shifts over time. As research on empowerment in projects continues to grow,...conference paper 2011

Schroijen, M.J.T. (author)Anthropogenic environmental impact is growing despite large technical efforts to reduce it. Its dependency on technology induced human behaviour makes designing for environmental impact reduction particularly difficult. Despite the fact that the sustainable conundrum is characterized as a “no technical solution problem”, a framework is proposed...doctoral thesis 2011

Dulam, R.V. (author)Project failure occurs due to several reasons, but complexity and underestimation of complexity are often seen as the cause. Because of the interdisciplinary character of projects, it seems that project management approaches are not sufficient to deal with the complexity of projects. Therefore the interdisciplinary aspect has to be considered...master thesis 2011

Arsalan Arshad, M. (author)Ever since sophistication of technology and human desire for a better, more comfortable and luxurious life have started to converge, it has had a direct impact on the way engineering projects are approached and handled. This is especially true since the second half of the previous century. A natural consequence of this is that conventional...master thesis 2011

Lesaja, G. (author), Roos, C. (author)We present an interior-point method for monotone linear complementarity problems over symmetric cones (SCLCP) that is based on barrier functions which are defined by a large class of univariate functions, called eligible kernel functions. This class is fairly general and includes the classical logarithmic function, the self-regular functions, as...journal article 2011

Christiaanse, S. (author)This graduation project offers an alternative to the tradition in top-down planning in the Netherlands. The test-case for this strategy is the transformation of former industry area ‘Schieoevers’ in Delft. Both a spatial framework and a policy framework are created to support bottom up development of this project location. The spatial framework...master thesis 2011

Kazzaz, A. (author)This thesis is the outcome of an ongoing persuasion to frame the meaning of the spatial planning practice and inquiry to the context through which urban areas evolve today. The research?oriented approach has been the consequent of a perceived lack of consolidated – technocratic – planning concepts to confront today’s challenges for the...master thesis 2011

D'Amelio, V. (author), Chmarra, M.K. (author), Tomiyama, T. (author)Developing multi-disciplinary products presents cross-disciplinary problems that are difficult to predict and to solve. Unfortunately, those cross-disciplinary problems are often discovered only at a later stage of the design through physical prototypes and can lead to modification of the conceptual design of a product. This is extremely costly...journal article 2011

Bouwers, E. (author), Lilienthal, C. (author), Visser, J. (author), Van Deursen, A. (author)Evaluating the complexity of the architecture of a softwaresystem is a difficult task. Many aspects have to be considered to come to a balanced assessment. Several architecture evaluation methods have been proposed, but very few define a quality model to be used during the evaluation process. In addition, those methods that do introduce a...report 2010

Bociort, F. (author)The presence of many local minima in the merit function landscape is perhaps the most difficult challenge in lens design. We present a simplified mathematical model that illustrates why the number of local minima increases rapidly with each additional lens added to the imaging system. Comparisons with results obtained with lens design software...conference paper 2010

Verwer, S. (author), De Weerdt, M.M. (author), Witteveen, C. (author)We develop theory on the efficiency of identifying (learning) timed automata. In particular, we show that: (i) deterministic timed automata cannot be identified efficiently in the limit from labeled data and (ii) that one-clock deterministic timed automata can be identified efficiently in the limit from labeled data. We prove these results based...journal article 2010

Schipper, H.R. (author)Due to the complexity of the freeform shapes it is often not possible to distinguish any repetitive elements in freeform buildings at all. Most freeform building designs consist of many single or double curved surfaces which require complex shapes for the mould and element edges. Since the costs of the moulds (formwork) for precast concrete make...conference paper 2010

Schut, E.J. (author)In order to keep innovating, engineers are working more and more with engineering software, providing them a way to cut away their routine and repetitive activities. Computer aided design and simulation software are for instance considered standard tools in most engineering companies. Today, to solve complex engineering design problems,...doctoral thesis 2010

Kramer, N.D.F. (author)Population growth and immigration increase the demand for mass housing developments all over the world. These developments are widely criticized for being mono-functional, mono-typological, and mono-cultural. This project is a design method for a new kind of mass housing. All design rules are reformulated as algorithms, that interact with each...master thesis 2010

Rui, J. (author), Heijungs, R. (author)With solid theoretical support from industrial ecology, an increasing number of industrial ecosystems (including eco-industrial parks and industrial symbiosis) have been created all over the world. There is no doubt that the Kalundborg symbiosis, which has steadily operates for thirty years, is our successful exemplar, although some problems...conference paper 2010
