Available in PDF, EPUB and Kindle. Book excerpt: The primary focus of this dissertation is on the quantification of actor interaction and the dissemination of information through social networks. Social networks have long been used to model the interactions between people in various social and professional contexts. These networks allow for the explicit modeling of the complex interrelations between relevant individuals within an organization and the role they play in the decision making process. This dissertation considers social networks represented as network flow models in which actors have the ability to provide some level of influence over other actors within the network. The models developed incorporate performance metrics and reliability analysis established in the multi-state reliability literature to gain insights into organizational behavior. After a brief introduction, Chapter 2 provides a survey of the relevant literature on several topics of interest within this dissertation. In Chapter 3, actor criticality findings using traditional social network analysis are compared to those obtained via multi-state reliability importance measures. Chapter 4 extends the model developed in Chapter 3 to consider that an actor's social interaction and level of influence within the organization are not only multi-valued and stochastic in nature but also a function of the interactions with its neighbors. A Monte Carlo simulation model is presented to evaluate the reliability of the network, and network reliability is evaluated under various influence communication rules. In Chapter 5, a hierarchical network structure is investigated where actors are arranged in layers and communication exists between layers. A probability mass function is developed to compute the expected level of influence at the target nodes as a function of the existing communication paths within the network. An illustrative example is used to demonstrate the effects on expected influence at the target as connections are either added or removed and when the uncertainty associated with an actor's influence level is removed. Finally, in Chapter 6, a methodology is developed for eliciting the probabilities associated with the influence levels used in the network analysis of Chapters 3 - 5.

Book Synopsis Network Reliability and Resilience by : Ilya Gertsbakh
Download or read book Network Reliability and Resilience written by Ilya Gertsbakh and published by Springer Science & Business Media. This book was released on 2011-09-05 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to the probabilistic description of the behavior of a network in the process of random removal of its components (links, nodes) appearing as a result of technical failures, natural disasters or intentional attacks. It is focused on a practical approach to network reliability and resilience evaluation, based on applications of Monte Carlo methodology to numerical approximation of network combinatorial invariants, including so-called multidimensional destruction spectra. This allows to develop a probabilistic follow-up analysis of the network in the process of its gradual destruction, to identify most important network components and to develop efficient heuristic algorithms for network optimal design. Our methodology works with satisfactory accuracy and efficiency for most applications of reliability theory to real –life problems in networks.

Book Synopsis Social Network Analysis and Education by : Brian V. Carolan
Download or read book Social Network Analysis and Education written by Brian V. Carolan and published by SAGE Publications. This book was released on 2013-03-14 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an introduction to the theories, methods, and applications that constitute the social network perspective. Unlike more general texts, this title is designed for those current and aspiring educational researchers learning how to study, conceptualize, and analyze social networks. The author′s main intent is to encourage you to consider the social network perspective in light of your emerging research interests and evaluate how well this perspective illuminates the social complexities surrounding educational phenomena. Whether your interests lie in examining a peer′s influence on students′ achievement, the relationship between social support and teacher retention, or how the pattern of relations among parents contributes to schools′ norms, the tools introduced in this book will provide you with a slightly different take on these and other phenomena. Unlike other approaches, this perspective accounts for the importance of relationships within formal structures, and the informal patterns of interaction that emerge, sustain, or recede. Relying on diverse examples drawn from the educational research literature, this book makes explicit how the theories and methods associated with social network analysis can be used to better describe and explain the social complexities surrounding varied educational phenomena.

Book Synopsis Performance and Reliability Analysis of Computer Systems by : Robin A. Sahner
Download or read book Performance and Reliability Analysis of Computer Systems written by Robin A. Sahner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Performance and Reliability Analysis of Computer Systems: An Example-Based Approach Using the SHARPE Software Package provides a variety of probabilistic, discrete-state models used to assess the reliability and performance of computer and communication systems. The models included are combinatorial reliability models (reliability block diagrams, fault trees and reliability graphs), directed, acyclic task precedence graphs, Markov and semi-Markov models (including Markov reward models), product-form queueing networks and generalized stochastic Petri nets. A practical approach to system modeling is followed; all of the examples described are solved and analyzed using the SHARPE tool. In structuring the book, the authors have been careful to provide the reader with a methodological approach to analytical modeling techniques. These techniques are not seen as alternatives but rather as an integral part of a single process of assessment which, by hierarchically combining results from different kinds of models, makes it possible to use state-space methods for those parts of a system that require them and non-state-space methods for the more well-behaved parts of the system. The SHARPE (Symbolic Hierarchical Automated Reliability and Performance Evaluator) package is the `toolchest' that allows the authors to specify stochastic models easily and solve them quickly, adopting model hierarchies and very efficient solution techniques. All the models described in the book are specified and solved using the SHARPE language; its syntax is described and the source code of almost all the examples discussed is provided. Audience: Suitable for use in advanced level courses covering reliability and performance of computer and communications systems and by researchers and practicing engineers whose work involves modeling of system performance and reliability.
