Sediment Pathways on Ebb-Tidal Deltas: New Tools and Techniques for Analysis

In an era of rising seas and other challenges posed by climate change, coastal regions like the Netherlands are facing ever graver threats. Strategic sand nourishments could mitigate the threat of coastal erosion and sea level rise on barrier island coasts while limiting ecological impacts. However, insufficient knowledge of sediment transport...

A review of public transport transfer synchronisation at the real-time control phase

We perform a systematic review of real-time control strategies for transfer synchronisations in public transport. In particular, we review inter-station and intra-station control measures that can be applied in near real-time, including vehicle holding, stop-skipping, speed control, short-turning, rescheduling, interlining, rerouting, and...

Equilibrium analysis for linear and nonlinear aggregation in network models: applied to mental model aggregation in multilevel organisational learning

In this paper, equilibrium analysis for network models is addressed and applied in particular to a network model of multilevel organisational learning. The equilibrium analysis addresses properties of aggregation characteristics and connectivity characteristics of a network. For aggregation characteristics, it is shown how certain classes of...

Fast and robust scheme for uncertainty quantification in naturally fractured reservoirs

The main objective of this study is to perform Uncertainty Quantification (UQ) using a detailed representation of fractured reservoirs. This is achieved by creating a simplified representation of the fracture network while preserving the main characteristics of the high-fidelity model. We include information at different scales in the UQ...

Determination of REV and Effective Properties of Fluvial Depositional Systems: A feasibility study using 3D FLUMY models

Fluvial reservoirs are difficult to model due to the high permeability contrast between the sandstone bodies and the overbank deposits and the complex geometry of the permeable (sandstone bodies) and impermeable zones (overbank deposits). A set of fluvial meandering models has been generated using FLUMY. The models represent a range of Net-to...

A network approach to prioritize conservation efforts for migratory birds

Habitat loss can trigger migration network collapse by isolating migratory bird breeding grounds from nonbreeding grounds. Theoretically, habitat loss can have vastly different impacts depending on the site's importance within the migratory corridor. However, migration‐network connectivity and the impacts of site loss are not completely...

Neural Dynamics based on EEG and diffusion MRI: Potential in studying stroke

After stroke, functional recovery may be promoted during the first six months through rehabilitation. Several events are thought to lead to regaining lost functions, among which the remapping of affected limbs to other regions of the cortex is a frequent occurrence. High spatial resolution brain imaging techniques, like magnetic resonance...

Indoor A* Pathfinding through an Octree Representation of a Point Cloud

There is a growing demand of 3D indoor pathfinding applications. Researched in the field of robotics during the last decades of the 20th century, these methods focussed on 2D navigation. Nowadays we would like to have the ability to help people navigate inside buildings or send a drone inside a building when this is too dangerous for people....

Distributed Connectivity-Aware Multirobot Exploration

Networks of mobile robots enable us to explore areas quickly and without danger to human operators. To execute this task successfully, communication between the robots in the network is imperative. In this thesis, we link communication between robots to network integrity, where network integrity is defined as the ability of the network to...

Stationshus: A Scandinavian influenced approach and design for a strategic multi-modal intervention in Rotterdam South

Rotterdam South the largest problematic neighbourhood in the Netherlands and deals with large social and spatial problems. With the development of a Stationshus a large intervention is made, that connects the area to the national Intercity railway network and that at the same time forms a new centre for Rotterdam South, that connects the...

Meeting the Hague south west at the border

This graduation project focuses on improving the public space and pedestrian connections between the different neighbourhoods surrounding the station area of the Hague Moerwijk. In the present situation the station area of the Hague Moerwijk is not well accessible or visible from its surroundings and the existing qualities of the area are...

Connectivity in the regular polytope representation

In order to be able to draw inferences about real world phenomena from a representation expressed in a digital computer, it is essential that the representation should have a rigorously correct algebraic structure. It is also desirable that the underlying algebra be familiar, and provide a close modelling of those phenomena. The fundamental...

Simulation of connectivity of capillary porosity in hardening cement-based systems made of blended materials

In recent years, the durability of reinforced or prestressed concrete structures has become a main concern. A key parameter in durability predictions is the microstructure of the surface zone of concrete structures, i.e. the “covercrete”, more in particular the connectivity of the pores in the cement paste matrix. In this paper, the connectivity...

Connectivity-oriented urban projects

This thesis is about connections in the built environment, networked connections for the mobility of people at the smallest scale of the urban realm: the pedestrian scale. It deals with applications of the new science of networks as a tool for observation and assessment of connectivity in the urban space. It explores networks theoretically...

Fundamental Properties of Wireless Mobile Ad-hoc Networks

Wireless mobile ad-hoc networks are formed by mobile devices that set up a possibly short-lived network for communication needs of the moment. Ad-hoc networks are decentralized, self-organizing networks capable of forming a communication network without relying on any fixed infrastructure. Each node in an ad-hoc network is equipped with a radio...
