Survivability in layered networks
… thesis studies the problem of maximizing network survivability in the layered setting, with a focus on optimizing the embedding of the logical network onto the physical network. In the first part of the thesis, we start with an investigation of the fundamental properties of layered networks, and …

Farmer survivability in Virginia
… information is also important for farmer survivability. Producers in favorable financial condition own larger percentages of their operated land, and they utilize more family labor.

Survivability of time-varying networks
… poorly understood. In this thesis, we study the survivability properties of time-varying networks against unpredictable interruptions. We first show that the traditional definition of survivability is not effective in time-varying networks and propose a new survivability framework. To evaluate …

Survivability of interconnected ring networks
<i>Survivability</i> is a means of introducing redundancy in a network architecture which is utilized to maintain communication capability under failure conditions. The need for survivability exists in most communication networks. Fiber optic networks concentrate large amounts of traffic within a …

Multi-attribute tradespace exploration for survivability
Survivability is the ability of a system to minimize the impact of a finite-duration disturbance on value delivery (i.e., stakeholder benefit at cost), achieved through (1) the reduction of the likelihood or magnitude of a disturbance, (2) the satisfaction of a minimally acceptable level of value …

Multi-attribute tradespace exploration for US Navy surface ship survivability: a framework for balancing capability, survivability, and affordability
… tradeoffs in naval ship capability and survivability for the sake of affordability early in concept ship design gives Navy leadership real options for affordable ships and reduces the likelihood of detailed design changes late in the acquisition process. In the naval ship design process …

Framework for optimizing survivability in complex systems
… infrastructure such as hydroelectric dams' survivability at risk. Maximizing resiliency in complex systems can be viewed as a multi-objective optimization that includes system performance, survivability, economic and social factors. Systems requiring high survivability: a hydroelectric dam, …

An integrated approach to damage ship survivability assessment
This research concentrates on damage ship stability and means for assessing dynamic ship performance in this state. A consolidation of many approaches for tackling damage ship dynamics has been undertaken, culminating in the development of a numerical tool for simulating ship behaviour while …

Unintended Survivability: Comparative Reactions to Israel's Nuclear Posture
The overarching goal of this study is to conduct an investigation of regional perspectives on the impact of Israel's nuclear monopoly on nuclear decisions in the Middle East. This Dissertation addresses the question as to why regional actors have taken divergent nuclear paths relative to Israel's …

Survivability Against Intelligent Adversary in Next-Generation Wireless Networks
The conventional static spectrum allocation policy has resulted in a suboptimal use of spectrum resources, leading to over-utilization in some bands and under-utilization in others. As a solution, dynamic spectrum access-based Cognitive Radio Network (CRN) has been proposed. CRN allows secondary …

A system dynamics approach to aircraft survivability-attrition analysis
Mathematical representation of military operations have long fascinated analysts and practitioners. In 1916 English mathematician Frederick W. Lanchester represented the attrition rates of two opposing forces in the form of two differential equations, functions of the size and combat effectiveness …

Survivability modeling for cyber-physical systems subject to data corruption
… for dependability attributes, in particular, survivability, of cyber-physical systems. Any malfunction or security breach, whether cyber or physical, that causes the system operation to depart from specifications will affect these dependability attributes. Our focus is on data corruption, …

Growth and Survivability of Microorganisms at Martian Temperatures and Pressures
… As a comparison to methanogen growth and survivability, additional experiments were conducted using a non-spore-forming bacterium, Serratia liquefaciens, previously shown capable of growth at 7 mbar, 0 C and within an anoxic CO2 atmosphere. The experiments described here assessed the …
