OPAL: A Stereo Vision Obstacle Processing ALgorithm for a Walking Lunar Rover

The Lunar Zebro is a small six-legged robot. It has the potential to be used in a swarm carrying out objectives like exploring planetary surfaces. A new step towards autonomous navigation is made with the newly developed Obstacle Processing ALgorithm (OPAL) using primarily open-source libraries. This study showed that the initial iteration of...

Self-compacting high-performance fiber concrete for foundations: Part 1 -experimental verification and design considerations

An investigation is carried out into the applicability of self-compacting high-performance fiber concrete (HPFC) in foundations. A concrete mixture has been designed with a concrete cube strength of about 110 MPa. The concrete contains 60 kg/m³ steel fibers. The properties of the HPFC developed are very suitable for structural...

Do they really value your privacy?: An exploratory analysis of what can be learned about companies from their privacy statements

This master thesis explores to what degree information about a company's commitment to privacy can be extracted from a privacy statement. To do this, firstly a new database of more than 1500 privacy statements is created using Amazon Mechanical Turk. Next, 72 different aspects related to privacy of the statements are enumerated by using natural...

Using a generic spatial access method for caching and efficient retrieval of vario-scale data in a server-client architecture

This paper presents a methodology for using a generic data-driven spatial access method as a communication mechanism for vario-scale data in a server-client setting. As a complete data set is often quite large, it is managed at the server side and supporting different scale levels is important. We show that a generic R-tree like grouping method,...

Exploring the use of a generic spatial access method for caching and efficient retrieval of vario-scale data in a client-server architecture

Vario-scale data structures make it possible to derive maps at arbitrary scale. When requesting a map, data has to be transferred from server to client. This takes time, which affects the responsiveness of the system, and sometimes costs can be involved for every byte that is send over the network. Redundant data transfers should thus be avoided...

Structural assessment of existing timber roof structures for green roofs in Rotterdam

Green roofs, also known as vegetation roofs, are becoming very popular for residents of houses or apartments and for good reasons. Vegetation on rooftops have many benefits on global and local level. Expectations show that the climate change will lead to heavier storms and causes the sewers in Rotterdam to overflow. Hence, the municipality of...
