Animal burrows create discontinuities on the body of earthen levees that under certain circumstances can threaten their structural integrity through hydraulic alteration and surface erosion. Although it is a virtually established fact that discontinuities can undermine the structural integrity of levees, …

This paper evaluates a design procedure which is able to scale one-dimensional quadratic-residue diffusers, with integrated Helmholtz resonators. These acoustic structures can be tuned to room modes while fitting within a specified volume. An algorithmic solver is used to control geometric parameters …

In recent years, the number of human-induced earthquakes in Groningen, a large gas field in the north of the Netherlands, has increased. The majority of the buildings are built by using unreinforced masonry (URM), most of which consists of cavity (i.e. two-leaf) walls, and were not designed to withstand …

Part of the project: TFF-Optimization of Mixing Elements. Polymer mixing with a single screw extruder is a common process in industry. Mixing quality depends on (amongst others) the screw geometry. The main objective of this study was to quantify distributive mixing behavior of a single screw extruder …

VSTEP is a software development company that specializes in creating simulators for realistic virtual safety training. During my graduation period, I was assigned to work as a graphics programmer intern on environmental and nighttime effects in the company’s ship simulator NAUTIS. In the current version …

Revisioning the past by using current methods available to create a workflow that converts 2D housing plans efficiently and scientifially accurate into 3D geometry.

Developing and orchestrating classroom discourse about students' different solution methods is an essential yet complex task for mathematics teachers. This study reports on the first stages of classroom discourse development of one Dutch higher secondary school mathematics teacher who had no prior experience …

In this chapter, I look back at the implementation of W12-16, a major reform of mathematics education in the lower grades of general secondary education and pre-vocational secondary education in the Netherlands including all students aged 12–16. The nationwide implementation of W12-16 started in 1990 …

In this episode, I describe some activities on the history of geometry. Geogebra is first used to visualize a primary source from Descartes, and then to create the conchoide of Nicomedes. In the last part the so-called human conchoid is described, a form of embodied cognition to let your students get …

The following report gives a full description of the Bachelor Civil Engineering graduation project. The graduation is done in engineering firm Iv-Consult and the thesis topic is provided by Zwarts & Jansma Architects. Architectural bureau requires a structural solution for the roof of the ice skating …
