Zhang, X. (author), Ai, T. (author), Stoter, J.E. (author)Building patterns are important features in applications like automated generalization and spatial data mining. Many previous work has however focused on a few specific patterns (i.e. collinear pattern), while many others are less discussed. This paper proposes a comprehensive typology of available building patterns through the study of existing...conference paper

Ngene, P. (author), Radeva, T. (author), Westerwaal, R. (author), Schreuders, H. (author), Dam, B. (author)Using the change in the intrinsic optical properties of YMg-based thin films upon exposure to hydrogen, we observe the presence of hydrogen at concentrations as low as 20 ppm just by a change in color. The eye-visible color change circumvents the use of any electronics in this device, thereby making it an inexpensive H2 detector. The detector...conference paper

Li, C. (author), Wang, H. (author), Van Mieghem, P. (author)The largest eigenvalue ? 1 of the adjacency matrix powerfully characterizes dynamic processes on networks, such as virus spread and synchronization. The minimization of the spectral radius by removing a set of links (or nodes) has been shown to be an NP-complete problem. So far, the best heuristic strategy is to remove links/nodes based on the...conference paper

Van Ormondt, D. (author), Van der Veen, J.W.C. (author), Sima, D.M. (author), Graveron-Demilly, D. (author)In in vivo metabolite-quantitation with a magnetic resonance spectroscopy (MRS) scanner, the model function of the attendant MRS signal is often only partly known. This unfavourable condition requires semi-parametric estimation. In the present study the unknown part is the form of the decay function of the MRS signal. The lack of knowledge is...conference paper

Bohemia, E. (author), Lauche, K. (author), Harman, K. (author)The purpose of this paper is to initiate discussion and guide a proposed workshop on issues in cross-institutional and cross-disciplinary design studios, with a focus on assessment. This paper overviews issues associated with the implementation and coordination of the Global Studio, a recent cross-disciplinary and cross-institutional teaching...conference paper

Eker, S. (author), Slinger, J.H. (author), Yucel, G. (author)Automated sensitivity analysis approaches in system dynamics focus primarily on model parameters. Although table functions are often subjectively approximated, they do not form the focus of most sensitivity analyses. Recently, a promising approach that allows automation of sensitivity analysis on functions was proposed by Hearne (2010), but the...conference paper

Blenn, N. (author), Doerr, C. (author), Van Kester, B. (author), Van Mieghem, P. (author)As Online Social Networks (OSNs) become an intensive sub- ject of research for example in computer science, networking, social sci- ences etc., a growing need for valid and useful datasets is present. The time taken to crawl the network is however introducing a bias which should be minimized. Usual ways of addressing this problem are sampling...conference paper

Yu, H. (author), Mulder, J.A. (author)The CleanEra project is initiated by the Faculty of Aerospace Engineering at Delft University of Technology. Significant reduction of noise impact on perimeters of airports via arrival trajectory optimization is considered as one of the major targets of the project. In this paper, an aircraft model and its acoustic performance are introduced to...conference paper

Daalhuizen, J. (author), Badke-Schaub, P. (author), Fokker, J. (author)Different approaches of design methodology that have been developed throughout the history of the design methods movement have produced many insights into the structure of the design process (Alexander, 1964; Simon, 1969; Schön. 1983; Hubka and Eder, 1987; Pahl and Beitz. 1984; Roozenburg and Eekels, 1995). It seems however, that little of this...conference paper

Williams, P. (author), Ockels, W.J. (author)The tethered space elevator could provide a revolutionary means for enabling cheap transportation to geostationary altitude and beyond. Assuming that such a system can be built, one of the dynamic design problems is determining a means of moving the elevator along the tether so as to minimize the residual librational motion of the elevator...conference paper

Beshir, A.A. (author), Kuipers, F.A. (author), Van Mieghem, P. (author), Orda, A. (author)In WDM networks, survivable routing and wavelength assignment (SRWA) involves assigning link-disjoint primary and backup lightpaths. In the on-line SRWA problem, a sequence of requests arrive and each request is either accepted or rejected based only on the input sequence seen so far. For special networks, we establish on-line algorithms with...conference paper

Nourian Ghadikolaee, P. (author), Rezvani, S. (author), Sariyildiz, I.S. (author), Van der Hoeven, F.D. (author)In a quest for promoting sustainable modes of mobility, we have revisited how feasible and suitable is it for people to walk or cycle to their destinations in a neighbourhood. We propose a few accessibility measures based on an 'Easiest Path' algorithm that provides also actual temporal distance between locations. This algorithm finds paths that...conference paper

Fiscaletti, D. (author), Elsinga, G.E. (author), Westerweel, J. (author)The present work involves the investigation of the fine scale motions in the turbulent region of a high Reynolds number air jet. In the fully developed region of the jets, the small scales of turbulence are assumed to be isotropic, and expected to contain elongated vortices (worms), whose diameter scales with the Kolmogorov length scale. Aimed...conference paper

Many of these new questions however require an automatic assessment of...conference paper

Based on learning and evaluation theories and concepts we discuss qualitative and quantitative evaluation processes, and its relationship to short training sessions to foster sustainable development. Short training sessions solve barriers for...conference paper

Buob, M.O. (author), Uhlig, S. (author), Meulle, M. (author)BGP is used today by all Autonomous Systems (AS) in the Internet. Inside each AS, iBGP sessions distribute the external routes among the routers. In large ASs, relying on a fullmesh of iBGP sessions between routers is not scalable, so route-reflection is commonly used. The scalability of route-reflection compared to an iBGP full-mesh comes at...conference paper
