Air Traffic Control Advisory System for the Prevention of Bird Strikes

Bird strike prevention in civil aviation has traditionally focused on the airport perimeter. Since the risk of especially damaging bird strikes outside the airport boundaries is rising, this PhD thesis researches the safety potential of operational bird strike prevention involving pilots and controllers. In such a concept, controllers would be...

Analysis of Risk-Based Operational Bird Strike Prevention

Bird strike prevention in civil aviation has traditionally focused on the airport perimeter. Since the risk of especially damaging bird strikes outside the airport boundaries is rising, this paper investigates the safety potential of operational bird strike prevention involving pilots and controllers. In such a concept, controllers would be...

Geovectoring: Reducing Traffic Complexity to Increase the Capacity of UAV airspace

Both U-space in Europe, as well as UTM in the USA, develop concepts and tools for UAV airspace. Enabling highdensity operations is one of the goals of these studies. Past and recent studies have analysed which factors affect the capacity of a UAV airspace. An improved understanding of this can lead to control methods for capacity management. Two...

Potential of peer-to-peer bike sharing for relieving bike parking capacity shortage at train stations: an explorative analysis for the Netherlands

In the Netherlands, many (mainly larger) train stations suffer from capacity shortages for bicycle parking as the result of a large increase in the use of the bicycle as a feeder mode. Sharing of parked bicycles with arriving train passengers who are in need of a bicycle for some time would decrease the number of parked bicycles and reduce the...

Beyond a Complete Failure: The Impact of Partial Capacity Degradation on Public Transport Network Vulnerability

Disruptions in public transport networks (PTNs) often lead to partial capacity reductions rather than complete closures. This study aims to move beyond the vulnerability analysis of complete failures by investigating the impacts of a range of capacity reductions on PTN performance. The relation between network performance and the degradation of...

Risk Assessment and Mitigating Measures Regarding Pile Installation at EBS Biohub Jetty

During the design phase of the reconstruction of the existing mooring facility “EBS Biohub” at the port of Rotterdam, the Netherlands, a high risk profile was recognized in the proximity of four new dolphins next to the existing jetty. The risk originated from the greater installation depth of the dolphins related to the limited foundation depth...

Beyond a complete failure: The impact of partial capacity reductions on public transport network vulnerability

Disruptions often result with partial capacity reduction without resulting with a complete breakdown. This study aims to move beyond the analysis of complete failure by investigating the impacts of partial capacity reduction on public transport network performance. We analyse the relation between the extent of capacity reduction at the line...

Modelling public transport congestion: A comparison of static and dynamic models

Competences in Context: Knowledge and capacity development in public water management in Indonesia and The Netherlands

International cooperation for reaching development goals has expanded gradually since the 1950s. The effectiveness of the Overseas Development Aid (ODA) has become a topic of great public interest. A growing body of experience exists to demonstrate that finance alone is not sufficient for development, and capacity and knowledge are increasingly...

A capacity analysis of the railway line Rotterdam?Dordrecht (NL)

Although the Dutch railway network is one of the busiest ones in Europe, it is still not completely future?proof; the limits of the current rail system are reached. In some cases major adaptions to the timetable require adjustments to the tracks themselves to come to a valid operating plan. Besides, the robustness of the network in case of...

Upgrades and Conversions of Floating Offshore Units: An Overview

Evaluation of anchorage international airport using the airport business suite

Stochastic modelling of train delays and delay propagation in stations

A trade-off exists between efficiently utilizing the capacity of railway networks and improving the reliability and punctuality of train operations. This dissertation presents a new analytical probability model based on blocking time theory which estimates the knock-on delays of trains caused by route conflicts and late transfer connections in...

Influence of loading rate on pile capacity in unsaturated sand

When in-situ tests are performed to determine the ultimate capacity of a pile after the installation, quite a lot of types of tests are available. The following tests are generally used, in order from most used method to least used method: the static testing method, dynamic testing methods, pseudostatic and statnamic testing methods. During a...

Comparison of some methods to determine the delays of landing aircraft with respect to runway capacity

The capacity of runways in use for landing aircraft may become the chief bottleneck of the capacity of airports. This runway capacity may result in long queues of aircraft waiting for landing, which in its turn results in unacceptable delays. Two analytic methods to determine these delays are described and the results are compared. The two...
