Indirect economic ties of trade and investment, long overlooked by literature on the relationship between economics and conflict, reduce hostility between states. In a globalized world, states are tied not only by their direct connections, but also by dense and interlocking conn…

Capturing the changes between two biological phenotypes is a crucial task in understanding the mechanisms of various diseases. Most of the existing computational approaches depend on testing the changes in the expression levels of each single gene individually. In this work, we …
Why do some terrorist groups last much longer than others? This dissertation is among a small but growing number of studies to apply social networks analysis to the study of terrorism, and addresses an outcome of interest that is important but under analyzed. Terrorist group sur…
Low demand for index insurance in several recent pilot programs has created a puzzle for development economists and policy makers concerned with enhancing farmers risk management capacity in low-income economies. Chapter 1 contributes to the resolution of this puzzle by providin…
This thesis presents the realization of novel systems for optical sensing networks with an array of long-period grating (LPG) sensors. As a launching point of the thesis, the motivation to implement optical sensing network in precisely catering LPG sensors is presented. It highl…
The goal of this thesis is to develop statistical and learning algorithms for the design, analysis, measurement, and modeling of networking and security systems with specific focus on RFID systems, network performance metrics, user security, and software security. Next, I give a…
The goal of this thesis is to identify measurement, modeling, and optimization opportunities for large scale networks -- with specific focus on cellular networks and online social networks. These networks are facing unprecedented operational challenges due to their very large sc…
This research looks into the use of artificial intelligence combined with regression approaches to improve the prediction and/or classification of risk for developing pressure ulcers (PU) in an inpatient academic hospital. The models were run using many different combinations of…
Much of the social capital literature focuses on unambiguous social situations where actors share generalized trust or interpersonal trust. Drawing on in-depth fieldwork in northwest Azerbaijan, this thesis focuses instead on distrust and the negotiation of conflicting interpret…
The first chapter of the dissertation investigates whether remittances affect child's schooling and labor outcomes in Bangladesh, specifically enrollment in school, labor and household chores participation and performance on reading, English and math tests. To control for the en…
This dissertation covers the two major parts of my Ph.D. research: i) developing a theoretical framework of complex networks and applying simulation and numerical methods to study the robustness of the network system, and ii) applying statistical physics concepts and methods to …
Presently, there is no up-to-date literature on the characterization of reputation and trust in wireless sensor networks (WSNs) which can be referenced by scientists, researchers and students. Although some research documents include information on reputation and trust, characte…
The main goal of this study is to examine the characteristics of the networks of Tehrani men and women (structure, composition, and content), their effects upon the flow of resources, and the association between the structure of network and marital relationships. In addition to …
It is usually assumed that the parameters of an optimization problem to be known numbers or scalars. Accordingly, the objective function value is a scalar or a point value. However, in real life, the parameters may not be known exactly and all we know about them is that they fal…
The heavily distorting channels limit the use of linear equalizers and the use of the nonlinear equalizers becomes admissible. Most nonlinear equalizers, e.g. Voltera type, are usually too complicated to meet real-time processing demands. Neural networks-based equalizers, especi…
Topological Design of Enterprise networks (ENs) is a hard problem. There, we resort to heuristics to come up with desirable solutions. Enterprise Network topology design problem comprises several conflicting objectives such as minimization of cost, minimization of network delay,…
An investigation has been made into symmetry features of patterns as a means by which the patterns are described, or with which they are transformed prior to classification in order to assist a pattern recognition system. There are two main points of departure from existing symm…
In an age of austerity, specifying how governance and innovation interact is an important issue on the agenda of policymakers and scholars when discussing the role of government in dealing with 'wicked problems'. This trend of public sector spending cuts continues unabated in G2…
The role of biraderi kinship networks has recently gained attention in U.K. elections. Biraderis are patriarchal and hierarchical kinship networks that are led by male elders and originate from Pakistan and Bangladesh. These networks have been accused of influencing selections a…
