Accurate sound field reproduction in rooms is often limited by the lack of knowledge of the room characteristics. Information about the room shape or nearby reflecting boundaries can, in principle, be used to improve the accuracy of the reproduction. In this paper, we propose a method to infer the location …

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 …

Sub-scale Flight Testing (SFT) is potentially useful in predicting aircraft flight behaviour, especially in the case of unconventional designs for which legacy information is unavailable and wind tunnel tests are unable to predict aircraft dynamics. A necessary condition for SFT is the design of properly …

In ancient times, music education was an essential part of mathematics education: in the Quadrivium mathematics, geometry, music and astronomy formed a four-unit whole. In China, among others, Confucius emphasized the importance of music education and the connection between poetry, law and music.
