The Rookwood Pottery Company was one of the most outstanding American pottery producers in the early 20th century. Rookwood produced a line of significant architectural facing tiles, unlike anything else produced in the Arts and Crafts tile industry. This thesis is an assimilation of all the primary product. Rookwood's catalogues, commissions, and artisans are discussed to illustrate the design and production significance Rookwood's product. The analysis will be valuable for the documentation and identification of tile installations produced by the Rookwood Pottery Company from 1903-1931. / Department of Architecture

Frequency-based ocean synthesis is a class of methods for generating ocean waves in deep water using physically based ocean spectra provided by oceanographic research. The output of these methods is a heightfield which is periodic and can be used to tile a larger area. However, when using a larger number of tiles, a repetition pattern becomes apparent. Wang tiling is a method of tiling the plane non- periodically by using only a small set of input tiles with given constraints. The aim of this thesis is to create a set of Wang Tiles, each of which represents an ocean heightfield synthesised by a frequency- based method, so one can create large ocean scenes without apparent periodicity in the tiling pattern.

This dissertation is devoted to the measure theoretical aspects of the theory of automata and groups generated by them. It consists of two main parts. In the first part we study the action of automata on Bernoulli measures. We describe how a finite-state automorphism of a regular rooted tree changes the Bernoulli measure on the boundary of the tree. It turns out, that a finite-state automorphism of polynomial growth, as defined by Sidki, preserves a measure class of a Bernoulli measure, and we write down the explicit formula for its Radon-Nikodim derivative. On the other hand the image of the Bernoulli measure under the action of a strongly connected finite-state automorphism is singular to the measure itself. The second part is devoted to introduction of measure into the theory of limit spaces of Nekrashevysh. Let G be a group and φ : H → G be a contracting homomorphism from a subgroup H < G of finite index. Nekrashevych associated with the pair (G, φ) the limit dynamical system (JG, s) and the limit G-space XG together with the covering ∪g∈GT · g by the tile T. We develop the theory of selfsimilar measures m on these limit spaces. It is shown that (JG, s,m) is conjugate to the one-sided Bernoulli shift. Using sofic subshifts we prove that the tile T has integer measure and we give an algorithmic way to compute it. In addition we give an algorithm to find the measure of the intersection of tiles T ∩ (T · g) for g ∈ G. We present applications to the evaluation of the Lebesgue measure of integral self-affine tiles. Previously the main tools in the theory of self-similar fractals were tools from measure theory and analysis. The methods developed in this disseration provide a new way to investigate self-similar and self-affine fractals, using combinatorics and group theory.

The field of nanotechnology has enabled scientists to perform fascinating engineering manipulations of biological substrates. Systems of DNA are now able to perform algorithmic computations by way of constructing biological modules composed of DNA macromolecules and using laboratory techniques available to biological sciences. The tile assembly model is an established model of biomolecular computing: using properties of DNA macromolecules to define constructions of self-assembling biological systems. The existing tile assembly model uses the concept of DNA tiles conceptually shaped as squares and exposes the tiles to carefully controlled biological conditions. The result is that under this process we can design and create these systems to compute solutions to algorithmic problems. Hexagons are the only two-dimensional regular polygon other than squares that can tile a plane infinitely leaving no space uncovered, where only translations of the initial polygon is allowed. Therefore hexagon-shaped DNA tiles can be defined to cover a planar surface, with the notable difference of six adjacent tiles per position versus the four adjacent neighbours in traditional four sided tiles. In this thesis, we will define a generalization of the tile assembly model that supports six-sided DNA tiles, in addition to the traditional four sides. We will introduce a problem known as the 0-1 Knapsack problem that is currently unsolved with square tiles. Moreover, a solution to the problem was attempted by tile assembly model researchers, however we show there is an error in their solution. After we analyze their solution and discover the shortcomings of square tiles under those constraints, we then show this fault is not applicable to hexagon tiles. Therefore, we show that the 0-1 Knapsack problem is solvable using hexagon shaped tiles.

En el presente trabajo se muestra un estudio de pre factibilidad para la instalación de una planta productora de baldosas de plástico reciclado para piso y pared donde se evalúa la viabilidad técnica, económica-financiera y de mercado. En un principio se mencionan los aspectos generales como objetivos, hipótesis y marco referencial. Luego, se presenta el estudio de mercado, donde se detalla la demanda, exportaciones, importaciones y producción nacional con el objetivo de obtener una demanda interna aparente y posteriormente ajustarla con diversos factores y así obtener la demanda de proyecto. / This work presents a pre-feasibility study for the installation of a plant to produce recycled plastic tiles for floor and wall where the technical, economic-financial and market viability is assessed. First, it mentions the general aspects and objectives, hypothesis and frame of reference. Then, it presents the market research, where demand, exports, imports and domestic production is detailed with the aim of obtaining an apparent domestic demand and subsequently it is adjusted with various factors and finally is obtained the project demand. / Trabajo de investigación

The aim of this thesis is to create a business plan for an existing company Design Bath, which operates as a wholesale and exclusive distributor of company PORCELANOSA Grupo on the Czech market of ceramic tiles. The plan is focused on building and extending current distribution network of PORCELANOSA Grupo products and should serve as a background for future decision making process and development of long-term strategy of company Design Bath. On the basis of this business plan we should be able to evaluate its feasibility. The theoretical part of this thesis contains basic introduction into business plans from theoretical point of view and market research methodology. The practical part includes the description of international and Czech market of ceramic tiles in order to understand the business opportunity. Description of competition, market research, proposal of suitable forms of distribution and financial plan are all included in the practical part in the way that the chapters logically follow each other. Financial plan revealed that the business plan is viable. Potential risks and conditions of successful realization complete the last part of the thesis.
