In this paper, we present a new method for detecting in-plane displacements in microelectromechanical systems (MEMS) with an unprecedented sub-ångström accuracy. We use a curve-fitting method that is commonly employed in spectroscopy to find peak positions in a spectrum. We fit a function to the intensity profile of the image of a silicon beam...

Seismic interferometry allows for the creation of new seismic traces by cross correlating existing ones. With sufficient sampling of remote-source positions, it is possible to create a virtual source record by transforming a receiver location into a virtual source. The imaging technique developed here directly retrieves reflectivity information...

The determination of wave conditions in partly sheltered areas is a challenging task for coastal engineers. Knowledge about these conditions is important for the design of coastal structures, the planning and operation of ports. Numerical models play an important role in the assessment of these conditions. Various types of models have been...

The South-Holland coast of the Netherlands undergoes the influence of the Rhine river plume released from the Rotterdam waterways. An experiment, STRAINS, was conducted to study the impact of the fresh water on the nearshore hydrodynamics and sand transport. As part of the experiment, an instrumented bottom frame measured the near-bed...

In this paper, the decision-making process behind the RE support policy will be explored in order to answer the following research questions: “why has the policy-making process been revised so many times?” and “how can such a drastic change on the RE support policy be explained?” The answer is found by making use of Lindblom's incrementalism...

For an initial design or assessment of a reinforced concrete solid slab bridge, spreadsheet-based or hand calculations are typically used. The shear stress is compared to the shear capacity as prescribed by the code. The distributed loads result in a uniform shear stress at the support. Concentrated loads are less straightforward to take into...

In het discours over het stedelijk landschap staat al een paar jaar het concept smart city centraal. Als gevolg van de revolutie in data- en communicatietechnologie vindt een grootscheepse stedelijke reorganisatie plaats die is gebaseerd op slimme technologieën. Steden moeten efficiënter, veiliger en schoner. Bij aanvang van het symposium De...

The goal of the Human Power Team from the TU Delft and the Free University of Amsterdam is to break the world speed record in unpaced cycling (Sam Whittingham, 133.28 km/h). The design of such a faired recumbent bicycle is a challenge. The Delft design, called VeloX (Human Power Team (2013)), is a fully-faired monocoque front-driven recumbent...

Background and Purpose: Thrombus characterization is increasingly considered important in predicting treatment success for patients with acute ischemic stroke. The lack of intensity contrast between thrombus and surrounding tissue in CT images makes manual delineation a difficult and time consuming task. Our aim was to develop an automated...

This paper describes the development of a model to simulate a dinghy sailors’ body temperature during a sailing match. This simulation has been developed as part of the master thesis by the author: “Thermal optimization of competitive sailing gear”. A literature study is done to define the human body heat balance and thermal comfort. Next a...

Urban sprawl phenomenon has been a huge issue since 20th century characterized by a rapid and unbalanced settlement development with transportation network particularly in a suburban area. The improvement of public transport system is a major requirement to minimize urban sprawl. Academic researchers have explained the linkage strategy between...

As indoor sports shoes are intensively used in a warm and sweaty environment for periods of up to three consecutive hours, the built-up heat inside is insufficiently released causing warm and perspiring feet. This results in an increased chance of blisters and skin irritations. Experimental research on the ventilation properties of the shoe was...

We investigated the off-line metrology for line edge roughness (LER) determination by using the discrete power spectral density (PSD). The study specifically addresses low-dose scanning electron microscopy (SEM) images in order to reduce the acquisition time and the risk of resist shrinkage. The first attempts are based on optimized elliptic...

The paper presents the answer to the question how pedalling on a specific recumbent bicycle, such as the VeloX3, influences a cyclist’s ability to steer the bicycle. The research aims to find the correlation between pedalling and the undesired steering movements it creates. To test this assumption a test setup was constructed. On this setup...

This paper presents the results of an international collaborative study5 of non-profit housing; one of the main alternatives to public housing developed in many countries. The study involved researchers6 in three countries using a common methodology to engage the leaders of non-profit organisations themselves in the research process. The paper...

Regional design is a practice that has in recent decades frequently been applied in spatial planning processes in The Netherlands. The making and use of spatial representations of plausible futures of regions was employed to refine physical implementation strategies and simultaneously, by reaching out for broad, sometimes public, attention, to...

We present the architecture and three applications of the largest resolution image sensor based on single-photon avalanche diodes (SPADs) published to date. The sensor, fabricated in a high-voltage CMOS process, has a resolution of 512 × 128 pixels and a pitch of 24 ?m. The fill-factor of 5% can be increased to 30% with the use of microlenses....

In this paper we present a novel method to determine the time of occurrence of tidal slack with a GPS receiver mounted on an anchored buoy commonly used to delineate shipping lanes in estuaries and tidal channels. Slack tide occurs when the tide changes direction from ebb to flood flow or from flood to ebb. The determination of this point in...
