To reach for abstraction is a major but challenging goal in mathematics education: teachers struggle with finding ways how to foster abstraction in their classes. To shed light on this issue for the case of geometry education, we align theoretical perspectives on embodied learning and abstraction with …

When waves interact with surfaces of different structures they are reflected, and these reflections are mainly caused due to less wave energy being dissipated by the surface of the structure. Naturally, rock slopes or permeable structures (mangroves forests, brushwood material, etc.) are used around …

The Procedural Interior Showroom Generator is a tool made using Blender geometry nodes to assist the Letink Design 3D team in creating virtual showroom environments using procedural modelling.   To define the design theory behind the Procedural Interior Showroom Generator, the main research question …

Engineers design levees without taking into account animal activity. But in reality: *Levees attract burrowing animals *Many of them are protected (e.g. beavers) *It is not always easy to detect burrows and remove them Topics of interest are: 1. Eco engineering approaches for deterrence of animals …

Growing volumes of wood are being used in construction, interior architecture, and product design, resulting in increasing amounts of wood waste. Using this waste is challenging, because it is too labor-intensive to process large volumes of uneven wood pieces that vary in geometry, quality, and origin. …

Resolutions of certain toroidal orbifolds, like T6/ℤ2 × ℤ2, are far from unique, due to triangulation dependence of their resolved local singularities. This leads to an explosion of the number of topologically distinct smooth geometries associated to a single orbifold. By introducing a parameterisation …

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 …

This paper presents a generic trim problem formulation, in the form of a constrained optimization problem, which employs forces and moments due to the aircraft control surfaces as decision variables. The geometry of the Attainable Moment Set (AMS), i.e. the set of all control forces and moments attainable …

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 …
