The present difficulties of the Technological University education. A short review is given of the many educational and technical difficulties which have to be overcome by the Technical University of Delft. Een kort overzicht wordt gegeven van de vele onderwijskundige en technische moeilijkheden waarmee de technische Hogeschool kort na de Tweede...

A new bed-load transportmeter has been designed particularly for very fine bed material (below 400 micron). The basic conception is the same as for the so-called Delft-bottle used for measuring transport by turbulent suspension. The instrument is of the flow-through type. The flow enters through a narrow and relatively high nozzle and is...

This paper gives a survey of the theoretical investigations in Holland on the motion of salt and fresh water in estuaries, locks, etc. The insight gained is set forth, and also questions yet unsolved are mentioned. First the long wave phenomena in the interface of two sharply separated liquids are treated, and in connection herewith, the cases...

The designing engineer often comes across the economic decision problem in which the "benefit" of a higher design criterion must be weighed against the "cost". Several methods have been developed to deal with this optimization problem; none of them, however, offer the possibility of introducing the appropriate considerations of a general policy...

Coastal engineering problems concerning wind waves and swell can be solved with the aid of hydraulic or mathematical models. The irregular wave field i.e. the state of the sea surface can be described in a sufficient way for engineering problems either by parameters such as significant wave height and mean wave period, or in the form of power...

We demonstrate new technologies for SPECT imaging with unsurpassed resolution in mice and rats. Results of the imaging of living animals will be shown. In addition development of detectors for next generation systems with an even higher resolution will be shown.

The evaluation of dynamic Traffic Engineering (TE) algorithms is usually carried out using some specific network(s), traffic pattern(s) and traffic engineering objective(s). As the behavior of a TE algorithm is a consequence of the interactions between the network, the traffic demand and the algorithm itself, the relevance of TE may depend on...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...
