This book offers a rigorous analysis of the achievements in the field of traffic control in large networks, oriented on two main aspects: the self-similarity in traffic behaviour and the scale-free characteristic of a complex network. Additionally, the authors propose a new insight in understanding the inner nature of things, and the cause-and-effect based on the identification of relationships and behaviours within a model, which is based on the study of the influence of the topological characteristics of a network upon the traffic behaviour. The effects of this influence are then discussed in order to find new solutions for traffic monitoring and diagnosis and also for traffic anomalies prediction. Although these concepts are illustrated using highly accurate, highly aggregated packet traces collected on backbone Internet links, the results of the analysis can be applied for any complex network whose traffic processes exhibit asymptotic self-similarity, perceived as an adaptability of traffic in networks. However, the problem with self-similar models is that they are computationally complex. Their fitting procedure is very time-consuming, while their parameters cannot be estimated based on the on-line measurements. In this aim, the main objective of this book is to discuss the problem of traffic prediction in the presence of self-similarity and particularly to offer a possibility to forecast future traffic variations and to predict network performance as precisely as possible, based on the measured traffic history.

Despite the large research effort in both public and commercial companies, no textbook has yet been written on this subject. This book aims to provide an overview to the topic of Carbon Capture and Storage (CSS), while at the same time focusing on the dominant processes and the mathematical and numerical methods that need to be employed in order to analyze the relevant systems. The book clearly states the carbon problem and the role of CCS and carbon storage. Thereafter, it provides an introduction to single phase and multi-phase flow in porous media, including some of the most common mathematical analysis and an overview of numerical methods for the equations. A considerable part of the book discusses the appropriate scales of modeling, and how to formulate consistent governing equations at these scales. The book also illustrates real world data sets and how the ideas in the book can be exploited through combinations of analytical and numerical approaches.

A basic coarse-grained model of mucus dynamics and structure is proposed and assessed. Mucins are replicated as chains of 20 beads, that each represent a domain with certain characteristics. The attractive ones make the chains attach to each other, and hence a dynamic network is formed. The typical properties of this network are due to the interactions among hydrophobic domains as the model system undergoes sol-gel transition as function of temperature. We developed a MD model to study this transition and the network structure. The force computations are done with the help of FENE and Lennard Jones (LJ) potentials. Three different beads are identified: cysteine rich, polar, and hydrophobic. They interact with LJ interactions with different strengths. The interactions along the chain structure are calculated with the help of FENE potential as are those between cysteine rich domains. The structure of the resulting gel network is studied for a range of temperatures.

We demonstrate a methodology for establishing orbits for the abundant, un-catalogued, yet dangerous, small orbital debris that will become observable with planned improvements to the Space Fence. Although roughly 15,000 orbital objects are present in the SSN catalog, it is believed that at least 200,000 objects that are massive enough to cause significant damage are in Earth orbit. With improvements to the Space Fence, LEO debris down to 5 cm in size may become observable. The additional hundreds of thousands of observations a day of mostly un-catalogued objects will present a significant data processing challenge. Of particular concern are the large numbers of observations that are uncorrelated either to a known object or to a single object. To deal with the large-scale uncorrelated track (UCT) problem, we have ported the Covariance-Based Track Algorithm (CBTA) into the supercomputer-based Testbed Environment for Space Situational Awareness (TESSA) in order to perform simulations at scale. CBTA bins UCTs for which initial orbits and initial covariance matrices could be determined back to a common epoch and then uses a statistical measure to see if they correlate given the state vectors and covariance matrices at that common time. If they do, the observations from the two tracks are combined and orbit determination (OD) is used to attempt to fit an orbit to the combined tracks. If OD converges, a new UCT hypothesis is created and the state and covariance of that hypothesis is saved with the other pre-existing UCTs. If a certain number of tracks are successfully combined then they are used to create a new catalog object. Old UCTs are weeded out of the pool of hypotheses when they become obsolete, or when at least some of the observations are used to create a new catalog object.

Biofidelic computer models are an invaluable tool in the understanding injury biomechanics. One crucial feature of these models is the ability to accurately capture the response of the individual tissues comprising the anatomy under study. In this thesis, we presented a simulation-based approach to describe the stress-strain response of cranial bone in mammals that can be applied to animal studies for model validation purposes as well as in human head injury studies. First, we explicitly characterized a microstructure specimen by generating large biofidelic meshes from [mu]CT images provided by the U.S. Army Research Laboratory (ARL). These meshes capture the intricate structures of the specimen for the model of cranial bone. In addition, different constitutive models were considered to describe the stress-strain response of the constituent cranial bone. Large-scale parallel finite element simulations were conducted and compared to experimental results of uniaxaial compression tests of cranial bone of adolescent Göttingen minipigs also conducted at ARL. The experiments show a significant amount of strain localization at different global strain levels, while exhibiting an apparent full elastic recovery upon unloading. Based on the experimental observations, it was found that an elastic hyperfoam model is an excellent candidate for describing the constituent material response. A detailed finite element model using the hyperfoam model for the constituent was able to capture both the stress-strain response and strain localization observed experimentally. The validated full-resolution simulations developed provide the pathway to develop homogenized constitutive models for cranial bone based on microstructural parameters that can be characterized experimentally.

Abstract: Computer-aided simulations are valuable research tools for investigation of the properties of nuclear materials at atomic scale. This is because in principle, comparing with the experimental techniques, any system could be computed, including the experimentally challenging radiotoxic materials, and the only limitation is the availability and performance of the supercomputing resources and the approximate character of computational methods. Here we present an overview of our research activities on atomistic simulations of materials related to nuclear waste management. We discuss various structural, chemical, energetic, thermodynamic and radiation damage resistance properties of phosphate-based ceramic waste forms and nuclear graphite. Emphasis is put on selecting a reliable computational methodology. Our atomistic modeling effort complements the relevant experimental studies. We demonstrate that the combined atomistic modeling and experimental studies result in superior characterization of the investigated nuclear materials.
