Graph Theory for the Middle School.

Robinson, Laura Ann 15 August 2006 (has links) (PDF)
After being introduced to graph theory and realizing how it can be utilized to solve real-world problems, the author decided to create modules of study on graph theory appropriate for middle school students. In this thesis, four modules were developed in the area of graph theory: an Introduction to Terms and Definitions, Graph Families, Graph Operations, and Graph Coloring. It is written as a guide for middle school teachers to prepare teaching units on graph theory.

Multi-Colored Maps from False Color Separations: Kirtland Examples (1800-1900)

Bryan, James D. 01 January 1980 (has links) (PDF)
Cartographers utilize primary and secondary colors in producing color maps. It is relatively easy to print the primary colors of magenta, cyan, and yellow on photo paper. It is considerably more difficult to print the secondary colors of red, blue, green, orange, purple, seagreen, and leafgreen consistently.This thesis has solved the problem associated with producing photographic color for cartographic maps. A new system of developing color maps has been developed. This system has produced: (1) pure blacks, (2) suitable secondary colors, (3) pastel colors, and (4) mid-value and dark colors.

Sistemas de equações polinomiais e base de Gröbner

Vilanova, Fábio Fontes 10 April 2015 (has links)
The main objective of this dissertation is to present an algebraic method capable of determining a solution, if any, of a non linear polynomial equation systems using Gröbner basis. In order to accomplish that, we first present some concepts and theorems linked to polynomial rings with several undetermined and monomial ideals where we highlight the division extended algorithm, the Hilbert Basis and the Buchberger´s algorithm. Beyond that, using basics of Elimination and Extension Theorems, we present an algebraic solution to the map coloring that use 3 colors as well as a general solution to the Sudoku puzzle. / O objetivo principal desse trabalho é, usando bases de Gröbner, apresentar um método algébrico capaz de determinar a solução, quando existir, de sistemas de equações polinomiais não necessariamente lineares. Para tanto, necessitamos inicialmente apresentar alguns conceitos e teoremas ligados a anéis de polinômios com várias indeterminadas e de ideais monomiais, dentre os quais destacamos o algoritmo extendido da divisão, o teorema da Base de Hilbert e o algoritmo de Buchberger. Além disso, usando noções básicas da Teoria de eliminação e extensão, apresentamos uma solução algébrica para o problema da coloração de mapas usando três cores, bem como um solução geral para o puzzle Sudoku.
