Towards a standardized statistical correction between RANSe-based full-scale CFD and sea trial measurement

This research considers Amels LE and SX super yachts. Bare hull, appended hull, and actuator disk simulations were performed using CFD, and compared to sea trial results. The results of the CFD are unique because they were generated after the sea trials were conducted, resulting in the ship speed in CFD and sea trial being similar. The results...

Credit to SMEs? Robust Lending Decisions with Exploratory System Dynamics Modelling and Analysis

This project’s commissioner, the head of ING’s emerging markets credit trading desk developed a loan structure called Revenue Participation Loan to fit the needs of SMEs in emerging markets. He now wants to combine this new product with innovation in his approach to uncertainty. With these types of loans SMEs agree to pay a fixed percentage of...

In search for robustness: Combining System Dynamics and exploratory Multi- Criteria Decision Analysis

System Dynamics and Multi Criteria Decision Analysis are two decision aid methods that aim at helping decision makers to better understand the world through formal models and computations. System Dynamics with the use of feedback loops and time delays helps to understand the behavior of a system and how the various elements affect this behavior....

Using NOMOS measurements to assess improvements of ECAC Doc. 29 aircraft noise calculations

The amount of air traffic worldwide is increasing, with an adverse effect on aircraft noise in the vicinity of airports as a result. Measurements and calculations have complementary benefits and limitations for the assessment of aircraft noise. A common method for the calculation of aircraft noise is ECAC Doc. 29. Various improvements of this...

Uncertainty Estimation in Vision-Aided Robot Teleoperation System

Teleoperation allows the use of human intelligence and decision making in remote tasks which are too dangerous for humans to perform. Technologies such as force feedback and haptic guidance have shown to increase task efficiency during teleoperation. In an unmodeled environment, sensors provide input for haptic guidance or present extra...

Visualization of Fiber Tract Uncertainty during Neurosurgery

In modern neurosurgical practice, a surgeon can see a patient’s fiber tracts (nerve tracts) on a monitor in the operating room. This design study investigates the benefit of adding the uncertainty of the tracts and aims to improve the surgeon’s orientation while reducing visual clutter.<br/><br/>Based on an interview with a neurosurgeon and our...

Shared Mobility-on-Demand Systems: Reducing service unreliability

On-demand ridesharing might be an effective solution to reduce traffic congestion and, as a result, reduce emissions to mitigate environmental issues. However, travel times are more uncertain in ridesharing services compared to non-shared transit services due to their shared nature. For example, at one moment, the users are informed that the...

Impact of leader-follower behavior on evacuation performance: An exploratory modeling approach

Different leader-follower behavior may be observed in models, such as group gathering, backtracking, and flexibility of the group. However, a comparison of these behaviors resulting in possible substantially different estimates of optimal evacuation procedures is lacking. Hence, we developed an Agent-based model in combination with exploratory...

The role of DSSs in decision-making processes characterized by time pressure, uncertainty and dynamism: an agent-based modeling approach

The effect of using decision support systems in decision-making processes characterized by time pressure, uncertainty, and dynamism is still very limited and debated among researchers. By utilizing a case study that concerns the employment of a DSS to assist the procedures of intercepting fugitives undertaken by the Dutch National Police, this...

The probabilistic assessment of trench sedimentation in sand wave fields: Based on a case study at the Borssele Wind Farm Zone

For the transportation of the produced energy at offshore windfarms to the onshore grid, export cables have to be installed in the sea bed. Usually, at first trenches are dredged, in which approximately one month later the cables are installed. During this period the trench should remain sufficiently open to install the cables, fulfilling the...

Very long term development of the Dutch Inland Waterway Transport System: Policy analysis, transport projections, shipping scenarios, and a new perspective on economic growth and future discounting: Extended summary report

This report, that provides an extended summary of a similar named thesis, addresses how a new method for the evaluation of policies with a very long term impact on the Dutch Inland Waterway Transport (IWT) system can be developed. It proposes an outline for a very long term transport model, prepares a number of very long term scenarios, and...

Technical feasibility of a Dutch radioactive waste repository in Boom Clay: Tunnel crossings

OPERA-PU-TUD321b<br/>Radioactive substances and ionizing radiation are used in medicine, industry, agriculture, re- search, education and electricity production. This generates radioactive waste. In the Neth- erlands, this waste is collected, treated and stored by COVRA (Centrale Organisatie Voor Radioactief Afval). After interim storage for a...

A numerical and reliability-based investigation into the technical feasibility of a Dutch radioactive waste repository in Boom Clay

OPERA-PU-TUD311<br/>The Onderzoeks Programma Eindberging Radioactief Afval (OPERA) is the third national research programme for the geological disposal of radioactive waste in the Netherlands, operating during the period 2011 to 2016. This document is the final report of Work Package 3.1, where the principal technical feasibility of the current...

From integration mainstreaming to convivial disintegration: how superdiversity shows the pitfalls of (mainstreaming) immigrant integration

The emergent literature on mainstreaming immigrant integration frequently references the term superdiversity. The diversification of migration is put forward as one rational for implementing measures to support immigrant integration across policy fields and across levels of policy making. In this paper I reflect on those assertions and argue...
