Building and roof type classification on 3D city models

In a rapidly evolving digital landscape, 3D city models have become more accurate and complex. Despite their widespread availability of open-source 3D city model datasets, these invaluable resources remain underutilized. Our primary goal centers on the classification of building and roof types. For our client, Spotr, our work directly impacts on...

Optimize the measurement of Poly-hydroxy-alkanoates (PHA) in biomass

Poly-hydroxy-alkanoate (PHA) is an intracellular polymer that can be used as an energy and carbon source by microorganisms. Measuring PHA is important for understanding the microbial metabolism of enhanced biological phosphorus removal (EBPR) and aerobic granular sludge (AGS) systems. There is a commonly used method to measure PHA, which is...

“Holonomy”: a non-Euclidean labyrinth game in virtual reality

A Comparative Study: Catholic Church in the Hague by Aldo van Eyck

The subject of the study is the architect Aldo van Eyck and his design of the church Pastoor van Ars designed in 1964 (completed in 1969) years. In the 1960s, Catholicism within the Netherlands was undergoing some new changes as a result of the Second Vatican Council, and the effects of this event were pervasive among all church. Figures such as...

SCIPoC: Semantic Classification of Indoor Point Cloud: A study into the possibilities of classifying indoor point cloud using a Deep Learning approach

With the constantly evolving range of applications for technology the quality and amount of data constantly increases as well. In this growing data environment, there is a constant search to provide more value to all data that is available for as little effort as possible. Our research tries to add such additional value by diving into the...

CO2MORROW: The role of CO2 in the agrifood sector in the transition to a cirular economy in the province of South Holland

The province of South Holland is a key player in the global food economy. However, its agrifood sector is currently generating unwanted outputs. CO₂emissions are the largest and most problematic output flow of this sector, causing negative externalities such as climate change and sea-level rise. Actors producing the CO₂...

A way to store, query, update an InSAR spatiotemporal dataset

In SAR interferometry, the data acquired by satellite are large. The points in the dataset are usually expressed in spatial-temporal dimension in which many epochs may be included. Extra information including contextual values and data from other sources sometimes are important to be taken into account when analyzing the deformation based on the...

Influence of 3D City Layout on Air Quality

In 2021, noise pollution monitoring will be mandatory in the Netherlands, which requires data on traffic that can be re-used for air quality estimation models. One of the important input parameters for the latter is the street type, which is required by the dilution parametrisation used within the air quality model.<br/>The goal of this project...

Humanizing Houston: Construction & Water Resilient Design of Downtown Houston

Testing mobile app based data gathering in the Phetchaburi River Basin and possible applications

The Phetchaburi River in Phetchaburi province, Thailand, has a watershed with many different water resource projects. The surrounding farms rely on the Phetchaburi River for irrigation water and the drinking water companies rely on it as a source of water. However, the Phetchaburi basin has problems with yearly floods, salt intrusion and...

Chemical Stability of Ceramic Membrane

A vario-scale approach that improves integration of point clouds with different point densities

Point clouds are becoming one of the most common ways to represent geographical data. The scale of acquisition of point clouds is growing steadily. However, point clouds are often very large in storage size and require computationally intensive operations. The integration of point clouds nowadays still face a lot of challenges. This project...

Afsluitdijk upgrading, non typical Dutch solutions

The Afsluitdijk (Enclosure Dam) is a major causeway in the Netherlands, which was constructed between 1927 and 1933, running from Den Oever on Wieringen in North Holland province, to the village of Zurich in Friesland province. The dam is 32 kilometers long and 90 m wide, with an initial height of 7.25 m above sea-level and a slope of 1:4 ...

Fieldwork coastal engineering: Preliminary design of a floating marina, Varna, Bulgaria

The beach in front of the hotel Sirius is suffering from a retreating coastline. Bathymetry and beach profiles were measured. With the data from previous years the long term evolution of the coast was analyzed. The main conclusions were that the beach in front of the Sirius hotel is still suffering from erosion and if this erosion trend...
