Characteristically, propagation of news on the Internet is a rather complex scenario. Its comprehensive understanding requires a consideration of diverse facets such as audience, problem domain, channel and type of news being propagated. My dissertation focuses on the understanding of propagation of a specific type of news- news articles, on a particular subset of the Internet, the social media. While a number of studies have looked into the phenomenon of propagation in social media, fewer of these have examined the propagation of content, specifically news articles, published by news provider websites. My dissertation presents a set of network theory based methodologies to extract and analyze various implicit propagation networks formed as a result of news article sharing on Twitter. These methodologies cover aspects related to users' article sharing behavior, influence of the news provider's social media accounts, role of followers and similarities between propagation networks of news providers. Furthermore, it also includes useful inferences derived about the news article propagation phenomenon by using a population sized data sampled from Twitter over a nine-month period. It expands on the inferences from my published works and the challenges identified in the area of news article consumption and distribution on the Internet. My dissertation intends to provide important guidelines for researchers and organizations studying social media related phenomena to derive insights about customer behavior. From the perspective of online news consumption and distribution, my study has important implications for the audience's preference of news content delivery. It also facilitates news providers to gauge their performance on social media and for news editors to help develop editorial policies tailored for an online consumer base. Finally, my dissertation presents an extensive set of network based models and methodologies that can enrich the applied network science discipline.

The objective of this research is to investigate different propagation models to determine if specified models accurately predict received signal levels for short path 900 MHz spread spectrum radio systems. The City of Denton, Texas provided data and physical facilities used in the course of this study. The literature review indicates that propagation models have not been studied specifically for short path spread spectrum radio systems. This work should provide guidelines and be a useful example for planning and implementing such radio systems. The propagation model involves the following considerations: analysis of intervening terrain, path length, and fixed system gains and losses.

[pt] A falha por fadiga nas estruturas e um problema muito comum que é caracterizado pela geração ou propagação paulatina de uma ou varias trincas e causada pela aplicação cíclica de cargas variáveis. A propagação das trincas bidimensionais tem sido estudada através de diferentes métodos numéricos que ajudam a descrever aproximadamente o valor do fator de intensidade de tensões ao longo da frente da trinca que é o parâmetro que controla a propagação. Porém, existem algumas expressões analíticas para trincas bidimensionais fornecidas na literatura que ajudam a descrever os fatores de intensidade de tensão e . Estas equações estão limitadas a diversos fatores de forma que relacionam as características geométricas da peça, espessura, largura e o tipo de entalhe já que as trincas bidimensionais mudam de aspecto a cada ciclo de carga. Contudo o processo de transição não tem sido acompanhado por estudos experimentais nem analíticos. Em especial, esta situação ocorre devido a que a transição acontece em poucos ciclos o que dificulta a sua medição. Esta pesquisa tem como objetivo geral estudar o processo de transição das trincas bidimensionais para unidimensionais com a utilização de um material transparente e com boas propriedades mecânicas como e o policarbonato. Experimentalmente, as trincas de fadiga bidimensionais se propagam em corpos de prova retangulares com defeito quarto - elíptico e são controladas sob condições de variável e baixa freqüência. Para calcular a vida total de uma trinca por fadiga, é preciso também modelar a transição. Foram tomados valores de comprimento experimentais a, c e c’ no processo de transição que nos permitem avaliar as taxas , e calculados os fatores de intensidade de tensão que controlam a transição. Os valores experimentais são também usados como dados de entrada num programa de análise numérica de propagação de trincas, o FRANC3D, o qual nos permite calcular os fatores de intensidade de tensão ao longo da frente da trinca quarto - elíptica. / [en] The fatigue failure of structures is a common problem that is characterized by the generation and propagation of one or several cracks caused by the cyclic application of variable loads. A crack is considered one-dimensional when the trajectory can be represented by a curve, as in the case where a surface crack pierces the entire thickness of a piece. If the crack penetrates partially in the specimen, it is considered to be two dimensional. Mathematical and physical models for simulating one-dimensional crack propagation by fatigue are widely known, and the main parameter that controls crack propagation is the stress intensity factor. However, the simulation of two-dimensional crack propagation has not yet reached the same state of development. There are some empirical expressions for two-dimensional cracks provided in the literature that help describe the stress intensity factors. These equations are limited to various form factors that relate the stress intensity to the geometrical characteristics of the piece. Also there are numerical methods that help describe some of the values of stress intensity factor along the crack front of a two-dimensional crack. An important question in calculating the total life of fatigue crack is describing the transition from a crack partially penetrating (two dimensional) for a one-dimensional (passing crack), because to calculate the total life of a fatigue crack is also necessary to model the transition. However, this process of transition has not for many geometries been described by analytical or experimental studies. One reason for this is that the transition often happens in a few cycles of load application, which complicates measurements. This research was aimed at investigating the process of transition from the two-dimensional crack to a one-dimensional crack with the use of polycarbonate a transparent material with good mechanical properties, polycarbonate. Experiments were conducted involving crack propagation in plates with a rectangular cross section. In each experiment, a crack was induced as a defect with a quarter-elliptical shape in one corner of the specimen. The propagation affected by the application of a low-frequency cyclic loading. Values of characteristic lengths of the two-dimensional shape of the crack (a, c and c ) were measured during the transition process, which allowed us to evaluate the rates of change of these parameters with the number of cycles N applied load and to evaluate the normalized stress intensity factors that control the transition. The experimental values are also used as input to a program for numerical analysis of crack propagation, the FRANC3D, which allows us to calculate the stress intensity factors along the front quarter-elliptical crack.

The propagation of waves through nonlinear media is of interest here, namely as it pertains to two specific examples, a nonlinear dielectric and a hyperelastic solid. In both cases, we examine the propagation of two-dimensional, weakly nonlinear, quasi-planar waves. It is found that such systems will have a nonlinearity that is intrinsically cubic, and therefore, a classical Zabolotskaya-Khokhlov equation cannot give an accurate description of the wave evolution. To determine the general evolution equation in such systems, a multi-timing technique developed by Kluwick and Cox (1998) and Cramer and Webb (1998) will be employed. The resultant evolution equations are seen to involve only one new nonlinearity coefficient rather than the three coefficients found in other studies of cubically nonlinear systems. After determining the general evolution equation, inclusion of relaxation, dispersion and dissipation effects can be easily incorporated. / Master of Science

Rock slope failures leading to rock falls and rock slides are caused by a multitude of factors, including seismic activity, weathering, frost wedging, groundwater and thermal stressing. Although these causes are generally attributed as separate causes, some of them will often act together to cause rock slope failures. In this work, two of the above factors, seepage of water through cracks and crack propagation due to the after effects of blasting are considered. Their combined impact on the development of rock falls and rock slides is modeled on ANSYS workbench using the Bingham Canyon mine slope failure of 2013 as a case study. Crack path modeling and slope stability analysis are used to show how a combination of crack propagation and seepage of water can lead to weakening of rock slopes and ultimate failure. Based on the work presented here, a simple approach for modeling the development of rock falls and rock slides due to crack propagation and seepage forces is proposed. It is shown how the information from remote sensing images can be used to develop crack propagation paths. The complete scope of this method involves demonstrating the combination of basic remote sensing techniques combined with numerical modeling on ANSYS workbench.

Sharing information securely between business partners and managing large supply chains effciently will be a crucial competitive advantage for enterprises in the near future. In this paper, we present a concept that allows for building value networks between business partners in a distributed manner. Companies are able to publish Linked Data which participants of the network can clone and subscribe to. Subscribers get noticed as soon as new information becomes available. This provides a technical infrastructure for business communication acts such as supply chain communication or master data management. In addition to the conceptual analysis, we provide an implementation enabling companies to create such dynamic semantic value networks.
