Mecânica das joias : estudo estrutural aplicado à concepção e ao desenvolvimentoSchwab, Felipe André January 2016 (has links)
A criação e confecção de joias, objetos de adorno, remete aos primórdios da humanidade. Ao longo da história as técnicas construtivas foram aprimoradas, porém os métodos produtivos do ramo joalheiro ainda hoje possuem forte caráter empírico de desenvolvimento. Nesse contexto, a presente pesquisa explora a possibilidade de simulação e avaliação do comportamento mecânico da joia, aplicada em etapas que precedem à produção. Busca-se como a análise estrutural por elementos finitos pode auxiliar o designer na avaliação de joias em processos de pré-fabricação. Para isso tem-se a criação dos corpos de prova gerados pela modelagem virtual, através do software Rhinoceros 3D. Os corpos de prova são exportados para o software Abaqus CAE, no qual são configuradas as propriedades do material, condições de carregamento e de suporte, simulando aspectos do uso diário da joia. Como material para simulação, são analisados aqueles mais utilizados no segmento, o ouro, a prata e o latão. Os resultados da simulação gerados no Abaqus CAE permitem avaliar as tensões geradas sobre o modelo, bem como os deslocamentos e deformações. Assim são identificados pontos frágeis na estrutura ou mesmo onde pode ter uma otimização da quantidade de material utilizado para cada joia, reavaliando a necessidade de aumentar ou reduzir o uso do material, buscando o equilíbrio estrutural do qual a joia necessitará. Os resultados obtidos comprovam que o método converge para uma importante ferramenta que proporciona dados sobre cada projeto a ser desenvolvido. Esses dados geram uma visão analítica onde as empresas podem definir qual a prioridade para cada projeto através de índices precisos, o que reduz a taxa de erro por projeto, auxilia no consumo adequado de matéria-prima, gerando economia de tempo e dinheiro. / The creation and production of jewelry, adornment objects, refers to the beginnings of humanity. Throughout the history, the construction techniques were improved, however the production methods of the jewelry industry today still have a strong empirical development and production. With this premise, the present research explores the possibility of simulation and evaluation of mechanical behavior for jewelry, in stages that are prior to production. With the application of external loads, the behavior of the jewelry through situations that may occur during the daily use can be analyzed. To create the study object it is used the software Rhinoceros 3D for make the virtual models. In the simulations the most used materials in the jewelry segment are analyzed, as gold, silver and brass. The Finite Element software Abaqus CAE is used for the structural analysis. The results show that the method is an important tool to provide data about the development of each project. These data give an analytical perception in which companies can define projects priorities through precise indexes, reducing error rates, helping in a suitable consumption of raw materials, saving time and money.

Návrh vývoje webových aplikací s automatickým vytvářením databázového schématu / Web Application Development Scheme with Automatic Database Schema CreationProchocká, Kristína January 2015 (has links)
This thesis designs and implements an intermediary layer on both the backend and the frontend part of a web application, together with a user interface used to show analysis outputs and to manage the data. This layer was designed based on analysis of several existing solutions, in various languages and environments, and implemented using MongoDB and PostgreSQL databases, written in PHP on the server side and in JavaScript on the client side. It offers an immediately usable flexible persistence layer directly in the frontend, with analysis, feedback and an option to convert collections to PostgreSQL while keeping the same API, enabling a fluent transition.

Strukturní analýza molekulárních krystalů / Structure analysis of molecular crystalsJaníček, Jakub January 2019 (has links)
Summary: Diploma thesis covers characterization of molecular crystals by X-ray structural analysis. N-carbamimidazoylisonikotinamid and 1-phenylguanidin were chosen, because their potential use in second harmony generation. Their salts with inorganic acids were prepared and determined their structures. Phase transition of 4,6-diaminopyrimidinium nitrate was studied by x-ray diffraction and differential scanning calorimetry. This phase transition is accompanied by thermosalient effect, causing that the crystals jump. Keywords: thermosalient, jumping crystal, X-ray diffraction, non-linear optics, N-carbamimidazoylnikotinamid, 1-phenylguanidin, 4,6diaminopyrmidin.

Advances in Flavonoid Glycosyltransferase Research: Integrating Recent Findings With Long-Term Citrus StudiesMcIntosh, Cecilia A., Owens, Daniel K. 01 December 2016 (has links)
Flavonoid glycosides are required for a number of crucial roles in planta and have the potential for development in a variety of agricultural, medicinal, and biotechnological applications. A number of recent advancements have been made in characterizing glycosyltransferases, the enzymes that are responsible for the synthesis of these important molecules. In this review, glycosyltransferases are considered with regard to biochemical properties, expression patterns, levels of enzyme activity during development, and structure/function relationships. This is presented with historical context to highlight critical findings, particularly with regard to the innovative work that has come from research on citrus species. The plant glycosyltransferase crystal structures that have been solved over the past decade, either alone or in complex with sugar donor and/or acceptor molecules, are discussed. The application of results from these structures to inform current structure/function work as well as implications and goals for future crystallography and tertiary modeling studies are considered. A thorough understanding of the properties of glycosyltransferases will be a critical step in any future biotechnological application of these enzymes in areas such as crop improvement and custom design of enzymes to produce desired compounds for nutritional and/or medicinal usage.
