Symmetric products of cubes
<p>If V is a finite set of points {V<sub>1</sub>, V<sub>2</sub>, …, V<sub>r</sub>} in some Euclidean space, E<sup>n</sup>, then the convex closure, C, of these points is a convex linear cell in E<sup>n</sup> whose vertex set is some subset of V. Given a (finite) collection of convex linear cells, …

White Cubes - Gendered Cubes : Einschreibungen von Geschlecht in die diskursiven Praktiken von Kunstmuseen ; eine Untersuchung am Beispiel der Hamburger Kunsthalle
… Doch Kunstmuseen sollten nicht als „White Cubes“ betrachtet werden, wie Brian O’Doherty diese Objektivität vortäuschende Ausstellungsinszenierung bezeichnete, sondern als interessengeleitete Instrumente der Wissensproduktion. Die vorliegende Studie zeigt mittels der Analyse der …

The implementation of a disambiguation marching cubes algorithm
… surface generation algorithm, the marching cubes algorithm, in computer volume visualization, with emphasis on the mathematical background and the ambiguity problem of the algorithm. A simple and elegant disambiguation algorithm is then described and implemented. Finally, generated data from …

Privacy-preserving data publishing and analytics using data cubes
Data cubes play an essential role in data analysis and decision support. In a data cube, data from a fact table is aggregated on subsets of the table's dimensions, forming a collection of smaller tables called cuboids. When the fact table includes sensitive data such as salary or diagnosis, …

Lines in Hales-Jewett cubes and other combinatorial results
In Chapter 1, we are concerned with the number of lines a set S <;;;; [n]d of a given size can contain. Here, a line in [n]d means a 'geometric line ', i.e. a set { x(ll, ... , x(n)} of n elements of [n]d such that for each 1 :::; i :::; d, the sequence x?), ... , x~n) is either strictly increasing …

Fast Discovery of Illegal State Cubes for Sequential Equivalence Checking
… patterns are considered which are illegal state cubes and represent and compact them using BDDs. A BDD implementation was created to compact these illegal states more efficiently. Discussion is then done on the parameters of the BDD implementation design which can be used more efficiently given …

Visual hulls for volume estimation : a fast marching cubes based approach
… can be computationally expensive. The marching cubes algorithm improves upon the voxel based model by replacing surface voxels with polygonal patches, removing the sharp voxel comers characteristic of voxel based models. The positional accuracy of each surface patch is improved through the …

Hamiltonian cycle and related problems : vertex-breaking, grid graphs, and Rubik's Cubes
In this thesis, we analyze the computational complexity of several problems related to the Hamiltonian Cycle problem. We begin by introducing a new problem, which we call Tree-Residue Vertex-Breaking (TRVB). Given a multigraph G some of whose vertices are marked "breakable," TRVB asks whether it is …

Direct imaging of self-assembly behaviors of colloids: from the microscale plates to the nanoscale cubes
Microscale and nanoscale colloidal particle self-assembly is widely studied to establish the design rules towards ordered structures and used as atomic model systems for phase transition studies such as crystallization and growth. The well-established synthetic library enables the synthesis of …

Lithographically Fabricated Micro-Reflectors for Sensitive Point of Care Diagnostics
… to antibodies. The particles, in the shape of cubes, serve as ultra-bright labels which are easily detectable using inexpensive, low-numerical aperture optics. The cubes, unlike traditional labels, are not susceptible to photo-bleaching and do not require any signal amplification. In this …

Time-Temperature Curing Relationship of an Adhesive Binder with Rice Straw
… the goal of this thesis was to study straw cubes (in lieu of the full-scale Stak Block) to discern a time-temperature relationship. A finite element (FE) model of the Stak Block was created to simulate the heating process. The results of this study indicated that the adhesive may actually …

The coloured cube test and the coloured mental rotation test: two new measures of spatial ability and mental rotation
… 2003), the new tests uses 3D colourful cubes, either as a standalone, or as a cube aggregate but with fewer elements. The test format is similar to the Raven’s Coloured Progressive Matrices Test (RCPM) which also served as a validation tool. The first new test, the Rotated Colour Cube …
