Van Breugel, K. (author)The increasing demand for quality, durability and sustainability requires a critical evaluation of currently used building codes. Although there is no doubt that we need codes, standards, certificates etc., the existence of these documents are no guarantee that the prescribed quality is realized on the building site. In this paper the essential...conference paper 2014

Mast, E.H.M. (author)The aim of this study is to develop a method to identify the barriers to and opportunities in the development of large-scale offshore wind energy in the Netherlands, taking into account the uncertainties of the future and consequences of decisions, from technological, economical, social, political and environmental perspectives. The research...doctoral thesis 2014

Jain, S. (author)This thesis discusses the role of flexibility of decisions when investing in projects that are affected by economic uncertainties. It uses the theory of real options to value such investment decisions. The thesis focuses on investment decisions related to nuclear power plants, which usually are affected by several sources of economic...doctoral thesis 2014

Qiu, Y. (author), Van Gijzen, M.B. (author), Van Wingerden, J.W. (author), Verhaegen, M. (author), Vuik, C. (author)In this paper, we consider preconditioning for PDE-constrained optimization problems. The underlying problems yield a linear saddle-point system. We study a class of preconditioners based on multilevel sequentially semiseparable (MSSS) matrix computations. The novel global preconditioner is to make use of the global structure of the saddle-point...report 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)This project is carried out on request of the BVOW, the interest group of the neighbourhoods Olofsbuurt and Westerkwartier in Delft, in order to propose solutions for the parking issue of Spoorzone Delft expected between 2015 and 2017. They are worried that parking disturbances will emerge in their neighbourhoods when the parking places of...report 2014

Timmermans, J. (author)This master thesis is about the design process of the modern creatives who work at Fabrique, a design agency in the Netherlands. To many the process of designing as successfully As Fabrique, can seem otherworldly. As Arthur C. Clarke once so aptly wrote: “any sufficiently advanced technology is indistinguishable from magic.” So how can Fabrique...master thesis 2014

Verhagen, H.J. (author), Jansen, L. (author)For describing the relation between the grainsize and the nominal diameter (d50 vs. dn50) usually a factor 0.84 is used. This factor has been derived by Laan [1981] "De relatie tussen vorm en gewicht van breuksteen (the relation between shape and weight of pieces of rock), report MAW-R-81079". However, this original report cannot be retrieved...report 2014

Carnevale, P. (author)A strong pressure towards efficiency improvements in the aviation sector is given by stringent environmental reduction goals and by the growing and volatile fuel prices. Such pressure is even stronger considering the steady growth of air traffic forecasted for the next 20 years. Structural mass reduction is one of the ways to achieve such...doctoral thesis 2014

Van Zadelhoff, G.J. (author), Stoffelen, A. (author), Vachon, P.W. (author), Wolfe, J. (author), Horstmann, J. (author), Belmonte Rivas, M. (author)Hurricane-force wind speeds can have a large societal impact and in this paper microwave C-band cross-polarized (VH) signals are investigated to assess if they can be used to derive extreme wind-speed conditions. European satellite scatterometers have excellent hurricane penetration capability at C-band, but the vertically (VV) polarized signals...journal article 2014

Kuijer, S.C. (author)Sustainable design faces challenges at a scale and level of complexity that are ill at ease with design’s mainstream focus on products and users. Recently, social practice theory has been suggested as a promising theoretical framework to inform new ways of designing. In social practice theory, practices – socially shared entities such as...doctoral thesis 2014

Van der Kuij, R.S. (author)Object of study is the organization of Real Estate Development by Dutch Housing Associations. Real estate development and housing associations seem like a logical combination. Real estate development has been one of the main activities housing associations have always been undertaking: developing dwellings for specific target groups, renovating...doctoral thesis 2014

Van Es, S.H.J. (author), Kolstein, M.H. (author), Pijpers, R.J.M. (author), Bijlaard, F.S.K. (author)Weld improvement techniques are aimed at reducing the notch effects of welds and generally focus on two aspects: a change of geometry of the weld toe and a change of the weld residual stresses. In this paper, fatigue tests are discussed, performed on butt welded specimens in steel grades ranging from S460 to S1100 in the TIG-dressed condition....journal article 2014

Assink, J.D. (author), Waxler, R. (author), Smets, P.S.M. (author), Evers, L.G. (author)In January 2011, the state of the polar vortex in the midlatitudes changed significantly due to a minor sudden stratospheric warming event. As a result, a bidirectional duct for infrasound propagation developed in the middle atmosphere that persisted for 2 weeks. The ducts were due to two zonal wind jets, one between 30 and 50 km and the other...journal article 2014
