▼ Visualizations of networks are critical to gain insights into complex systems, however, a complex network, which contains billions of nodes and edges, is incomprehensible. In this thesis, we focus on the simplification of large
scale-
free networks by maximizing the information content and minimizing the incomprehensibility of networks. An algorithm is developed to increase information content further by enabling the sizes of retained nodes to represent information lost. Our proposed method is verified through experimental study; the results reveal the optimal filtering strategy for large
scale-
free networks is retaining roughly top 9% of vertices based on their degree centrality. This method can be applied to visualize the main information of large
scale-
free networks or used as the pre-processing step for running other algorithms on networks

▼ This is a thesis about how to characterize the statistical structure of the tails of degree distributions of real-world networks. The primary contribution is a statistical test of the prevalence of
scale-
free structure in real-world networks. A central claim in modern network science is that real-world networks are typically "
scale free," meaning that the fraction of nodes with degree k follows a power law, decaying like k^-a, often with 2 < a < 3. However, empirical evidence for this belief derives from a relatively small number of real-world networks. In the first section, we test the universality of
scale-
free structure by applying state-of-the-art statistical tools to a large corpus of nearly 1000 network data sets drawn from social, biological, technological, and informational sources. We fit the power-law model to each degree distribution, test its statistical plausibility, and compare it via a likelihood ratio test to alternative, non-
scale-
free models, e.g., the log-normal. Across domains, we find that
scale-
free networks are rare, with only 4% exhibiting the strongest-possible evidence of
scale-
free structure and 52% exhibiting the weakest-possible evidence. Furthermore, evidence of
scale-
free structure is not uniformly distributed across sources: social networks are at best weakly
scale free, while a handful of technological and biological networks can be called strongly
scale free. These results undermine the universality of
scale-
free networks and reveal that real-world networks exhibit a rich structural diversity that will likely require new ideas and mechanisms to explain. A core methodological component of addressing the ubiquity of
scale-
free structure in real-world networks is an ability to fit a power law to the degree distribution. In the second section, we numerically evaluate and compare, using both synthetic data with known structure and real-world data with unknown structure, two statistically principled methods for estimating the tail parameters for power-law distributions, showing that in practice, a method based on extreme value theory and a sophisticated bootstrap and the more commonly used method based an empirical minimization approach exhibit similar accuracy.

▼ Preferential attachment networks with power law degree sequence undergo a phase transition when the power law exponent τ changes. For τ > 3 typical distances in the network are logarithmic in the size of the network and for 2 < τ < 3 they are doubly logarithmic. In this thesis, we identify the correct scaling constant for τ ∈ (2, 3) and discover a surprising dichotomy between preferential attachment networks and networks without preferential attachment. This contradicts previous conjectures of universality. Moreover, using a model recently introduced by Dereich and Mörters, we study the critical behaviour at τ = 3, and establish novel results for the scale of the typical distances under lower order perturbations of the attachment function.

▼ petal is a network analysis method that includes and takes advantage of precise Mathematics, Statistics, and Graph Theory, but remains practical to the life scientist. petal is built upon the assumption that large complex systems follow a
scale-
free and small-world network topology. One main intention of creating this program is to eliminate unnecessary noise and imprecision introduced by the user. Consequently, no user input parameters are required, and the program is designed to allow the two structural properties,
scale-
free and small-world, to govern the construction of network models.The program is implemented in the statistical language R and is freely available as a package for download. Its package includes several simple R functions that the researcher can use to construct co-expression networks and extract gene groupings from a biologically meaningful network model. More advanced R users may use other functions for further downstream analyses, if desired. The petal algorithm is discussed and its application demonstrated on several datasets. petal results show that the technique is capable of detecting biologically meaningful network modules from co-expression networks. That is, scientists can use this technique to identify groups of genes with possible similar function based on their expression information.While this approach is motivated by whole-system gene expression data, the fundamental components of the method are transparent and can be applied to large datasets of many types, sizes, and stemming from various fields.

▼ Wealth distribution is an important issue in Economics, especially wealth inequality. There are no absolutely perfect solutions to this issue long times ago. Despite we are in 21 century, the situation are getting worse and hard to resolve. We focus on developing an agent simulation model based on Evolutionary game and
Scale-
free network. From this model, we observed some phenomena in wealth distribution by changing the network structure. And we experiments 5 strategies to increase the connectivity of agents in network, which increasing the edges to fully-connected network or increasing the edges between two different groups. After these experiments, we find that the increasing of connectivity in the network is positive to the agentsâ wealth accumulation which means we build more relationship with the other people is benefit to our wealth accumulation. Furthermore, we divide the agents in the simulation to three groups: the poor, the middle class and the rich. In the group simulation, we find that increasing the connectivity inside the poor group is the best way to decrease the Gini coefficient and wealth inequality.

▼ The reliability of portable electronic devices was studied by applying standardized test procedures for test vehicles that represent the technologies and lead-free materials typically used in novel portable products. Thermal cycling and drop testing are commonly used because they reveal the failure modes and mechanisms that portable devices experience in operational environments. A large number of component boards were assembled in a full-scale production line to enable proper statistical and fractographic analyses. The test boards were assembled with different printed wiring board protective coatings, component under bump metallizations, and solder pad structures. The component boards were tested and the times-to-failure of the various combinations were statistically analyzed. The reliability data were also analyzed by the Weibull method, and the characteristic lifetimes and shape parameters were calculated. The failure modes under the thermal cycling, where solder interconnections fail by cracking through the bulk solder, were different from those observed in the drop tests, where cracks propagate along the intermetallic layers on either side of the interconnections. Under the thermomechanical loading the as-soldered microstructure, which is composed of only a few large eutectic colonies, undergoes local recrystallization that produces networks of grain boundaries along which the intergranular cracks damage solder interconnections. Under the mechanical shock loading, in turn, the strain–rate hardening of the solder material forces cracks to propagate in the intermetallic layers instead of the bulk solder. It was found that the reliability of solder interconnections can improve when the component boards have undergone thermal cycles before drop testing. The high-angle boundaries between the recrystallized grains generated during thermal cycling provide paths along which cracks can propagate but the propagation through the bulk solder consumes more energy than the propagation through brittle intermetallic layers. On the other hand, prolonged lifetime at elevated temperatures can reduce the drop test reliability considerably due to the formation of Kirkendall voids in the Cu3Sn intermetallic layers.

▼ Efficiently storing and processing massive graph data sets is a challenging problem as researchers seek to leverage “Big Data” to answer next-generation scientific questions. New techniques are required to process large
scale-
free graphs in shared, distributed, and external memory. This dissertation develops new techniques to parallelize the storage, computation, and communication for
scale-
free graphs with high-degree vertices. Our work facilitates the processing of large real-world graph datasets through the development of parallel algorithms and tools that
scale to large computational and memory resources, overcoming challenges not addressed by existing techniques. Our aim is to
scale to trillions of edges, and our research is targeted at leadership class supercomputers, clusters with local non-volatile memory, and shared memory systems.
We present three novel techniques to address scaling challenges in processing large
scale-
free graphs. We apply an asynchronous graph traversal technique using prioritized visitor queues that is capable of tolerating data latencies to the external graph storage media and message passing communication. To accommodate large high-degree vertices, we present an edge list partitioning technique that evenly partitions graphs containing high-degree vertices. Finally, we propose a technique we call distributed delegates that distributes and parallelizes the storage, computation, and communication when processing high-degree vertices. The edges of high-degree vertices are distributed, providing additional opportunities for parallelism not present in existing methods.
We apply our techniques to multiple graph algorithms: Breadth-First Search, Single Source Shortest Path, Connected Components, K-Core decomposition, Triangle Counting, and Page Rank. Our experimental study of these algorithms demonstrates excellent scalability on supercomputers, clusters with non-volatile memory, and shared memory systems. Our study includes multiple synthetic
scale-
free graph models, the largest of which has trillion edges, and real-world input graphs. On a supercomputer, we demonstrate scalability up to 131K processors, and improve the best known Graph500 results for IBM BG/P Intrepid by 15%.

▼ Trabalho apresentado no âmbito do Mestrado em Engenharia Informática, como requisito parcial para obtenção do grau de Mestre em Engenharia Informática
The exponential growth of the Internet, due to its tremendous success, has brought to light some limitations of the current design at the routing and arquitectural level, such as scalability and convergence as well as the lack of support for traffic engineering, mobility, route differentiation and security.
Some of these issues arise from the design of the current architecture, while others are
caused by the interdomain routing scheme - BGP. Since it would be quite difficult to add support for the aforementioned issues, both in the interdomain architecture and in the in the routing scheme, various researchers believe that a solution can only achieved via a new architecture and (possibly) a new routing scheme.
A new routing strategy has emerged from the studies regarding large-scale networks, which
is suitable for a special type of large-scale networks which characteristics are independent of network size: scale-free networks. Using the greedy routing strategy a node routes a message to a given destination using only the information regarding the destination and its neighbours,
choosing the one which is closest to the destination. This routing strategy ensures the following remarkable properties: routing state in the order of the number of neighbours; no requirements on nodes to exchange messages in order to perform routing; chosen paths are the shortest ones.
This dissertation aims at: studying the aforementioned problems, studying the Internet configuration as a scale-free network, and defining a preliminary path onto the definition of a greedy routing scheme for interdomain routing.

▼ Using the 2009 National Survey of Substance Abuse Treatment Services (N-SSATS), this paper uses logistic regressions to explore the effect of facility ownership on a facility’s show of altruism. Facility’s show of altruism is operationalized as a facility offering
free treatment to all its clients,
free treatment to some of its clients, or a facility offering a sliding fee
scale to its client base in order to absorb some of the cost of treatment based on a potential client's income. Region, receipt of public funds, and religious affiliation are added as covariates in order to gauge whether the potential relationship between facility ownership and a facility’s show of altruism is genuine. Results indicate that private, for-profit ownership status of a facility is associated with a lower likelihood that a substance-abuse treatment facility would engage in altruistic behavior. However, receipt of public funds acts as a mediating variable, in that, its inclusion raises the likelihood that a private, for-profit facility would engage in shows of altruism. Furthermore, it appears that religious-affiliation increases the likelihood that a facility would display altruism by providing
free treatment, to some of its clients, or to all, but less likely to display altruism by employing a sliding fee
scale. Overall, inclusion of region, receipt of public funds, and religious affiliation all produce statistically significant results, along with facility ownership. This suggests that there are a variety of variables, apart from facility ownership alone, that might be influential over a facility's show of altruism.

▼ Many processes and systems in nature and society can be characterized as large numbers of discrete elements that are (usually non-uniformly) interrelated. These networks were long thought to be random, but in the late 1990s, Barabási and Albert found that an underlying structure did in fact exist in many natural and technological networks that are now referred to as
scale free. Since then, researchers have gained a much deeper understanding of this particular form of complexity, largely by combining graph theory, statistical physics, and advances in computing technology. This dissertation focuses on out-of-equilibrium dynamic processes as they unfold on these complex networks. Diffusion in networks of non-interacting nodes is shown to be temporally complex, while equilibrium is represented by a stable state with Poissonian fluctuations.
Scale free networks achieve equilibrium very quickly compared to regular networks, and the most efficient are those with the lowest inverse power law exponent. Temporally complex diffusion also occurs in networks with interacting nodes under a cooperative decision-making model. At a critical value of the cooperation parameter, the most efficient
scale free network achieves consensus almost as quickly as the equivalent all-to-all network. This finding suggests that the ubiquity of
scale free networks in nature is due to Zipf's principle of least effort. It also suggests that an efficient
scale free network structure may be optimal for real networks that require high connectivity but are hampered by high link costs.

▼ In Spain, two smoke-
free laws have been passed after the approval of the FCTC. In 2005, it came into effect a smoke-
free legislation (Law 28/2005). This law was a great advance for public health in Spain; however, it was not complete in terms of health protection to secondhand smoke (SHS) exposure because it allowed smoking in hospitality sectors according to size of venues. The scientific evaluation of this law showed the need to promote a total ban and motivate the modification of the law in 2010 (Law 42/2010), extending the smoke-
free regulation to all hospitality venues without exception and to some outdoors areas, including hospital premises, educational campuses, and playgrounds.
The objectives of this doctoral thesis were: To assess the impact of the Spanish smoking legislations (Law 28/2005 and Law 42/2010) on tobacco epidemic (changes in consumption, dependence, motivation to quit and smoking cessation) among smokers of a general population cohort through self-reported information and biomarkers. To evaluate the impact of the Spanish tobacco control legislation on exposure to environmental tobacco smoke (self-reported and according to levels of cotinine in saliva) on non-smokers in a cohort population. To analyze the changes in the pattern of passive smoking of the non-smokers (displacement of exposure at workplace and leisure time to home) according to age, sex, and socioeconomic level. To analyze the correlation between the implementation of tobacco control policies and tobacco consumption, particularly rolling tobacco, electronic cigarettes (e-cigarettes) users and the intent to quit smoking in 27 countries of the European Union. To describe the acceptability of the recently implemented tobacco products regulations and to explore their relation with tobacco control legislation levels in Europe.
The results of this doctoral thesis has been conducted through seven scientific articles, four of them published in journals indexed in Web of Science and three of them in peer review in journals indexed in Web of Science (please see the Section Scientific Articles of this thesis). Moreover, during my training in this doctoral thesis I got involved in other two articles one published and the other in peer review, both in journals indexed in Web of Science.
In conclusion, the implementation of the two smoke-
free legislations in Spain is related to a reduction in smoking prevalence and SHS exposure (either using salivary cotinine concentrations or information on self-reported exposure). However, the consumption of other tobacco products, particularly hand-rolled tobacco, has increased specially among young population. A significant increase was found in the salivary cotinine concentration among adult continuing smokers after both Spanish legislations. After the implementation of the two Spanish smoke-
free bans, the main setting of SHS is in the leisure time and in work, where most of the exposed ones declared expending most of the time outdoor and not having specific areas for smokers. However, cotinine…

▼ The dramatic resurgence and emergence of epidemic dengue and dengue hemorragic fever in the last two decades neatly define a global pandemic. The dispersion of dengue viruses combines local infections of humans bited by infective mosquitoes inside a city with long-range transmissions to non-infective vectors that feed the blood of infected people arriving from other urban areas. In the present work a cellular automata model for dengue epidemic is proposed and investigated through large-scale computer simulations. The model takes into account the main features concerning the population dynamics of mosquitoes and humans and the disease transmission cycle. Furthermore, the model is defined on a scale-free network in which each node is a square lattice in order to properly describe the environment as urban centers interconnected through a national transportation system. A nonzero epidemic threshold is found and it is approached with a power law behavior by the density of infected individuals, as observed in the small-world network of Watts and Strogatz. Also, it is studied the importance of three parameters for the dengue spreading: the diffusivity of the mosquitoes, the probability of a mosquito bites humans, and the travel s probability of people between two interconnected cities. Finally, maps of infected individuals are obtained in order to caracterise the epidemic spreading.
O dramático ressurgimento e a emergência da epidemia de dengue e dengue hemorrágica nas últimas duas décadas claramente definem uma pandemia global. A dispersão do vírus da dengue combina infecções locais dos seres humanos picados por mosquitos infectados dentro de uma cidade com transmissões de longo alcance por vetores não-infecciosos que se alimentam do sangue de pessoas infectadas provenientes de outras zonas urbanas. No presente trabalho um modelo de autômatos celulares para epidemias de dengue é proposto e investigado através de siulação por computador, em larga escala. O modelo leva em conta as principais características relativas à dinâmica das populações de mosquitos e seres humanos e o ciclo de transmissão da doença. Além disso, o modelo é definido em uma rede livre de escala, em que cada nó é uma rede quadrada, a fim de descrever adequadamente o meio ambiente como os centros urbanos interligados através do sistema de transporte nacional. Um limiar epidêmico diferente de zero é encontrado e é aproximado com um comportamento tipo lei de potência pela densidade de indivíduos infectados, como observado na rede mundo-pequeno de Watts-Strogatz. Também, é estudada a importância de três parâmetros na dispersão da dengue: a difusividade do mosquito, a probabilidade do mosquito picar um ser humano, e a probabilidade de viagem de pessoas entre duas cidades conectadas. Por fim, mapas de indivíduos infectados são obtidos a fim de caracterizar a difusão da epidemia.

▼ This research presents a new method to estimate the local road vehicle miles traveled (VMT) with the concept of betweenness centrality. Betweenness centrality is a measure of a node’s or link’s centrality on a network that has been applied popularly in social science and we relate it to traffic volumes. We demonstrate that VMT on local roads exhibits a
scale-
free property: it follows two piecewise (double) power law distributions. In other words, the total local VMT can be obtained by properly connecting the two distributions at a breakpoint, each having a slope of the power law distribution. We show that the breakpoint can be predicted by using certain network topological measures, which indicates that the breakpoint may be an inherent property for a particular network. We also show that the highest betweenness centrality point can be estimated using network measures. Furthermore, we prove that the estimated VMT is not sensitive to the power of the power law distributions. This research highlights a potentially new direction of effort for local road VMT estimation.

▼ Converging evidence from a variety of fields, including psychiatry, suggests that
the temporal correlates of the brain’s resting state could serve as essential markers of a
healthy and efficient brain. We use ketamine to induce schizophrenia-like states in 32
healthy individuals to examine the brain’s resting states using fMRI. We found a global
reduction in temporal variability quantified by the time series’ standard deviation and an
increase in scale-free properties quantified by the Hurst exponent representing the signal
self-affinity over time. We also found network-specific and frequency-specific effects of
ketamine on these temporal measures. Our results confirm prior studies in aging, sleep,
anesthesia, and psychiatry suggesting that increased self-affinity and decreased temporal
variability of the brain resting state could indicate a compromised and inefficient brain
state. Our results expand our systemic view of the temporal structure of the brain and
shed light on promising biomarkers in psychiatry

▼ This is a thesis about how to characterize the statistical structure of the tails of degree distributions of real-world networks. The primary contribution is a statistical test of the prevalence of
scale-
free structure in real-world networks. A central claim in modern network science is that real-world networks are typically "
scale free," meaning that the fraction of nodes with degree k follows a power law, decaying like k
-a, often with 2 < a< 3. However, empirical evidence for this belief derives from a relatively small number of real-world networks. In the first section, we test the universality of
scale-
free structure by applying state-of-the-art statistical tools to a large corpus of nearly 1000 network data sets drawn from social, biological, technological, and informational sources. We fit the power-law model to each degree distribution, test its statistical plausibility, and compare it via a likelihood ratio test to alternative, non-
scale-
free models, e.g., the log-normal. Across domains, we find that
scale-
free networks are rare, with only 4% exhibiting the strongest-possible evidence of
scale-
free structure and 52% exhibiting the weakest-possible evidence. Furthermore, evidence of
scale-
free structure is not uniformly distributed across sources: social networks are at best weakly
scale free, while a handful of technological and biological networks can be called strongly
scale free. These results undermine the universality of
scale-
free networks and reveal that real-world networks exhibit a rich structural diversity that will likely require new ideas and mechanisms to explain. A core methodological component of addressing the ubiquity of
scale-
free structure in real-world networks is an ability to fit a power law to the degree distribution. In the second section, we numerically evaluate and compare, using both synthetic data with known structure and real-world data with unknown structure, two statistically principled methods for estimating the tail parameters for power-law distributions, showing that in practice, a method based on extreme value theory and a sophisticated bootstrap and the more commonly used method based an empirical minimization approach exhibit similar accuracy.

▼ An accurate prediction of propeller hull interaction is an important step in the design of a new vessel. The prediction of full-
scale flow phenomena, which eliminates
scale effects, is becoming available due to increasing computational power. However, the complexity of full-
scale CFD calculations combined with a lack of validation data results in unknown uncertainties. This study contributes to the uncertainty estimation for full-
scale calculations by answering the question With what uncertainty can we currently numerically predict resistance and propeller power on full-
scale Reynolds numbers?. The resistance and propeller flow predictions are done for the general cargo vessel MV-regal for three cases; a double body, a
free surface resistance simulation and an open water propeller simulation. The simulations are performed for the design speed of 14 knots, resulting in a full-
scale Reynolds number of 푅푒 = 1.12 ⋅ 10ዃ. The discretization error is determined by the grid refinement study as presented by Eça and Hoekstra for the propulsion parameters; resistance coefficients and the wake factor. For each case the flow field is analysed, an uncertainty assessment is made and the results are compared to a group of numerical results for the same simulation performed by 20 participants of a case study organised by Lloyd’s register on the same vessel as is considered in this thesis. Modelling the boundary layer of a flat plate on model and full-
scale Reynolds numbers encourages the use of unstructured grids for full-
scale Reynolds numbers. The uncertainties as predicted by the grid refinement study, vary between 0.6 and 24.5 percent for the friction coefficient. For the 푅푒 = 10
7 the values are compared to a structured grid study, which had a better trend over the grid refinement series. Comparison to theoretical friction coefficient calculations confirmed the absolute friction result. The double body simulation, performed on the full-
scale number 푅푒 = 1.12 ⋅ 10
9, demonstrated the use of the unstructured grids on the full-
scale Reynolds numbers. The iterative error had to be closely monitored in order to get a stable solution. While the iterative errors had the same order of magnitude, the uncertainties as predicted by the grid refinement study for the propulsion parameters varied between 1.5 and 140 percent. This is an unacceptable large scatter in uncertainty which calls for another method to determine the uncertainty. The
free surface simulation added complexity, by modelling the
free surface resistance of the vessel. The order of convergence is lower for the
free surface simulation, which creates a higher iterative error in the uncertainty assessment. The discretization uncertainty prediction varies between 2.7 and 23.5 percent. The open water simulation, which is based on a hybrid grid of structured and unstructured grids, showed for the monitored parameters a sufficiently low iterative error and a low discretization uncertainty (between 0.1 and 3.4 percent) for the thrust and torque…

▼ There are few aspects of modern life that remain unaffected by software, and as our day-to-day challenges change, so too must our software. Software systems are complex, and as they grow larger and more interconnected, they become more difficult to modify due to excessive change propagation. This is known as the ripple effect. The primary strategies to mitigate it are modular design, and minimization of coupling, or between-module interaction. However, analysis of complex networks has shown that many are
scale-
free, which means that they contain some components that are highly connected. The presence of
scale-
free structure implies high coupling, which suggests that software systems may be hard to modify because they suffer from the ripple effect.
In this thesis, a large corpus of open-source software systems is analysed to determine whether software systems are
scale-
free, whether
scale-
free structure results in high coupling, and whether high coupling results in ripple effects that propagate change to a large proportion of classes.
The results show that all systems in the corpus are
scale-
free and that that property results in high coupling. However, analysis of system evolution reveals that existing code is modified infrequently and that there is rarely sufficient evidence to be confident that ripple effects involving a high proportion of classes have actually occurred. This thesis concludes first that while it is desirable to avoid excessive interconnectivity, it is difficult to completely eliminate high coupling; and second, that the presence of high coupling does not necessarily imply poor system design.

▼ Academic networks derived from research papers, in particular citation and co-
author networks, have been studied widely. Although networks in an individual
discipline particularly physics have been studied substantially, the di erence across
di erent disciplines remains unclear. This thesis shows that networks generated in
computer science di er greatly the networks in Physics. The data used in our exper-
iment contain more than two million papers in DBLP and half a million papers in
Physical Review journals. We observe that both citation networks can be classi ed
as
scale-
free networks. Papers in DBLP has a shorter life than PR. And physicists
collaborate more closely than computer scientists in both citation and co-author net-
works. Collaborations evolve over time in both disciplines. For the ranking of papers,
we nd that the traditional PageRank algorithm is not appropriate for citation net-
works. We investigate the small-world characteristics in both kinds of networks in
terms of small average shortest path.

▼ Reliable computational modelling of chemical processes
in condensed phases such as computation of the activation
free
energies requires both extensive configurational sampling and an
appropriate level of theoretical treatment. The former is necessary
for capturing solute-solvent fluctuations (which is extremely
problematic in the energy-minimization approach) and for obtaining
convergent
free energies, while the latter is required for reliable
description of redistribution of electron density during chemical
processes and the corresponding energetics. These two factors make
computational cost of ab initio QM/MM (QM(ai)/MM) simulations
extremely high or even prohibitively expensive for the real system
of interest such as chemical reactions in aqueous solution and
enzymatic reactions. A powerful general approach, which circumvents
these problems, is the reference potential based Paradynamics
approach. In this approach the extensive configurational sampling
is performed at a lower level of theory using a cheaper
(computationally) reference potential rather than directly on the
expensive target QM(ai)/MM potential. This is followed by
calculating the
free energy perturbation of moving from the
reference potential to the target potential. ❧ In this work, a
number of advances is presented which are made to the QM(ai)/MM
free energy computation techniques in general and to the reference
potential strategy in particular. First, a formulation of the
reference potential based Paradynamics model is given. Chapter 1
addresses an important issue of improving the convergence of the
linear response approximation (LRA), which is used to calculate the
free energy perturbation from the EVB reference potential to the QM
target potential. The improvement in the LRA convergence is
achieved by iteratively reducing the difference between the two
potentials by fitting EVB parameters to the energy and its
derivatives of the target potential. A thorough comparative
analysis of the computational cost of the Paradynamics approach is
given relative to other methods based on the direct sampling of the
target potential. In Chapter 2, an extensive study exploring,
refining, and quantifying the Paradynamics model is given. First, a
different refinement strategy for a general reference potential is
formulated, where the difference between the reference potential
and the target QM/MM surface is reduced using the correction
potentials comprised of Gaussian functions along the reaction
coordinates. Additionally we propose a way of accelerating the
potential of mean force calculations by using a combination of the
same correction potentials along the reaction coordinates and a
solvent polarizing potential. Secondly, it is rigorously
demonstrated how to gradually and in a controlled way improve
calculations of the
free energy perturbations associated with
moving from the reference potential to the target QM/MM surface
using the multi-step
free energy perturbation approach.
Furthermore, the LRA treatment is validate by comparing it to the
full FEP…

▼ In this thesis, we study deterministic compartmental epidemic models. The conventional mass-mixing assumption is replaced with infectious disease contraction occurring within a heterogeneous network. Modeling infectious diseases with a heterogeneous contact network divides disease status compartments into further sub-compartments by degree class and thus allows for the finite set of contacts of an individual to play a role in disease transmission.
These epidemiological network models are introduced as switched systems, which are systems that combine continuous dynamics with discrete logic. Many models are investi- gated, including SIS, SIR, SIRS, SEIR type models, and multi-city models. We analyze the stability of these switched network models. Particularly, we consider the transmission rate as a piecewise constant that changes value according to a switching signal. We establish threshold criteria for the eradication of a disease or stability of an endemic equilibrium using Lyapunov function techniques. Simulations are also conducted to support our claims and conclude conjectures.
We test constant control and pulse control schemes, including vaccination, treatment, and screening processes for the application of these infectious disease models. Necessary critical control values are determined for the eradication of the disease.

▼ To capture the fracture process and non-linear behavior at the element and structural level of granular materials, concrete, under the presence of pre-existing imperfections, a constitutive model and a mesh
free method is derived in this study. For the constitutive model, a micromechanical approach with 2nd gradient theory is used to derive the stress-strain and double stress - strain gradient response of the material. For the mesh-
free method, an element-
free-Galerkin formulation is used. Results of the simulations show that the model qualitatively describes the failure mechanism and processes at the element and structural level. At the element level, the model describes the failure mechanisms, evolution, and behavior of concrete for different loading conditions (uniaxial, bi-axial, tri-axial, and shear). In addition, the model parameters are related to the material's mechanical properties and geometry, and therefore they have physical meaning. This model can be used to study the material's properties that need to be enhanced and/or modified for a particular interest. At the structural level, the mesh-
free method captures the fracture process and evolution of a 2D concrete plate under the presence of two types of inclusions subjected to tensile and compressive loading. Moreover, simulation results show that the proposed element-
free-Galerkin mesh-
free method overcomes the mesh-subjectivity and does not need adaptive analysis as it is observed in finite element methods

▼ Warm Mix Asphalt (WMA) was introduced in
Europe in 1995. WMA is gaining attention because it offers several
advantages over Hot Mix Asphalt (HMA). The advantages include (1)
reduced energy consumption in the asphalt mixture production
process; (2) reduced emissions, fumes, and undesirable odors; (3)
reduced binder aging;and (4) extended construction season in
temperate climates. Moisture damage can be
defined as the effect of environmental factors such as water,
temperature, and air on the performance of asphalt concrete
pavement. The asphalt mix consists of aggregate (in different
sizes) and asphalt binder being compacted to a specified air void
ratio. Due to traffic load with existence of water, asphalt
concrete mix will start to lose adhesion between aggregate and
binder or lose cohesion within the binder
itself. The main objective of this study is to
assess the performance of WMA and HMA in presence of water by using
nano
scale techniques and Surface
Free Energy (SFE)concepts, and
then compare the results with asphalt pavement traditional
laboratory tests. In this study, the bitumen’s
main functional groups were determined by using Fourier Transform
Infrared (FTIR) Spectroscopy. The mineral compositions of aggregate
were analyzed by using X-Ray diffraction (XRD) technique. Atomic
Force Microscopy (AFM) was used to measure the surface
free energy
of aggregate and asphalt binder. It can also be used to make a high
quality (Three Dimensional) images for smooth and leveled surfaces.
Asphalt mix samples were prepared in the laboratory using Superpave
Gyratory Compactor (SGC) with different thicknesses and diameters.
Half of the asphalt mix samples were conditioned to study the
effect of moisture on the performance of the mix. Air void
structure and aggregate orientation of the asphalt mix were
examined by using X-Ray Computed Tomography (X-Ray CT). X-Ray CT
images were analyzed by using computer software called AVIZO Fire
(version 6.3) to measure the air void ratio, void sizes, and void
distribution. Simple Performance Tester (SPT) was
used to perform dynamic modulus test. The test was performed on
both unconditioned and conditioned samples to compare the results.
MTS machine was used to perform the Indirect Tensile Strength (ITS)
on the unconditioned and conditioned asphalt mix samples. Thermal
cracking temperature for compacted asphalt sample was determined by
using Asphalt Concrete Cracking Device (ACCD). The permanent
deformation (Rutting) of asphalt concrete was determined by using
Asphalt Pavement Analyzer (APA). Based on the traditional
laboratory test results, all mixes are high resistant to moisture
damage with slight differences in the performance of HMA over
WMA. Dynamic modulus test results were used as
inputs to find the relaxation modulus and creep compliance. Two
asphalt mixes from two different plants in the state of Ohio were
evaluated. Based on the traditional laboratory
tests results, the performance of the HMA was higher than the WMA
for each project and this…

▼ Understanding transcriptional regulation of gene
expression on a genome-wide
scale is predicated on deciphering
interactions between all participating regulatory proteins and DNA.
Advances in genomics are facilitating the high-throughput
identification of these interactions, and graphs are emerging as
indispensable tools for explaining how the connections in the
network drive organismal phenotypic plasticity.In this work, I
first present an investigative inquiry whose goal was to identify
the source of unaligned sequence reads generated in studies aimed
at identifying transcription factor binding sites (TFBSs).
Determining TFBSs and the resulting architectures of gene
regulatory networks (GRNs) relies on chromatin immunoprecipitation
followed by massively parallel sequencing (ChIP-Seq) methods.
ChIP-Seq furnishes millions of short reads that, after alignment,
describe the TFBSs of a particular transcription factor (TF).
However, in all organisms investigated an average of 40% of reads
fail to align to the corresponding genome, with some datasets
having as much as 80% of reads failing to align. I describe here
the provenance of previously unaligned reads in ChIP-Seq
experiments from animals and plants. I show that a substantial
portion corresponds to sequences of bacterial and metazoan origin,
irrespective of the ChIP-Seq chromatin source. Unforeseen was the
finding that 30% - 40% of unaligned reads were actually align-able.
To validate these observations, I investigated the characteristics
of the previously unaligned reads corresponding to TAL1, a human TF
involved in lineage specification of hemopoietic cells. I show
that, while unmapped ChIP-Seq read data sets contain foreign DNA
sequences, additional TFBSs can be identified from the previously
unaligned ChIP-Seq reads. These results indicate that the
re-evaluation of previously unaligned reads from ChIP-Seq
experiments contributes significantly to TF target identification
and determination of emergent properties of GRNs.Secondly, I
describe the architectural organization and associated emergent
topological properties of GRNs that describe protein-DNA
interactions (PDIs) in several model eukaryotes. By analyzing GRN
connectivity, results presented here show that the anticipated
scale-
free network architectures are characterized by
organism-specific power law scaling exponents. These exponents are
independent of the fraction of the GRN experimentally sampled,
enabling prediction of properties of the complete GRN for an
organism. I further demonstrate that the exponents describe
inequalities in TF-target gene recognition across GRNs. These
observations have the important biological implication that they
predict the existence of an intrinsic organism-specific trans
and/or cis regulatory landscape that constrains GRN topologies.
Consequently, architectural GRN organization drives not only
phenotypic plasticity within a species, but is also likely
implicated in species-specific phenotype.Lastly, I discuss future
perspectives of this work. I briefly present models that…

▼ The purpose of this national study was to assess the
policies, procedures, and practices of 100% tobacco-
free campuses
and the extent to which they adhere to the American College Health
Association, (ACHA) guidelines to promote tobacco-
free campuses and
one of the first to use Rogers’ Diffusion of Innovations (DOI)
theory as the theoretical framework to assess the diffusion and
enforcement of tobacco-
free policies. The population included key
informants from flagship (versus satellite), 100% tobacco-
free
campuses listed in the American Nonsmokers’ Rights Foundation
(ANRF) directory (n=596). Key informants from 338 of the 596
campuses responded to the 41-item, online survey, yielding a
response rate of 56.7%. Analysis of the results showed some
evidence that a school’s adopter category within the DOI theory was
predictive of enforcement efforts regarding the campus’s
tobacco-
free policies, and that an institution's adopter category
within the DOI theory predicted adherence to ACHA guidelines and
recommendations for a tobacco-
free campus. Specifically, early
adopters had lower levels of compliance than early majority and
late majority adopters. Results from this study may help
higher-education administrators consider how best to develop,
implement, maintain, and enforce successful policy
change.

▼ Geostatistical modeling of natural phenomena is an
essential step in the development petroleum reservoirs and mineral
deposits. This numerical modeling involves simulation of the
geological attributes conditional to available relevant data
sampled at various scales. The simulation is usually performed at a
point scale on a grid of regularly spaced nodes. The simulated
results are non-reproducible and order dependent when another
simulation is performed on a closer spacing in some areas or for an
expanded study area. A grid-free geostatistical simulation (GFS)
method is proposed and developed in this thesis, where the
properties of natural phenomena are modeled as a function of the
coordinates of the simulation locations. The resulting realizations
are conditioned to the data values, preserve the spatial structure
of the modeled system, and the relationship between system's
variables. Simulation is performed at the point scale and can be
upscaled to larger volumes to establish block-scale realizations.
The conditioning data can be expressed as a set of scattered
point-scale data values or a set of regularly sampled block-scale
data values. Gridded block-scale data are converted to pseudo
point-scale values using a point-scale block value representation
technique to avoid artifacts in the simulated values. The grid-free
simulation proceeds as follows. The 1-D unconditional stochastic
processes are generated in a grid-free manner with a proposed
Fourier series simulation (FSS), where the target covariance
function is decomposed with a Fourier series, and simulation is
reconstructed with linear model of regionalization as a weighted
sum of the Fourier coefficients and periodic stochastic cosine
functions expressed as a function of the coordinates and a random
phase. 2-D and 3-D unconditional stochastic processes are simulated
grid-free using the modified turning bands concept, where a set of
1-D line processes with covariance functions related to the target
2-D/3-D covariance function is linearly combined to obtain
realizations in the higher dimensional space. In the modified
turning bands method, the bands are replaced with the points and
line process simulation is carried out with the FSS as a function
the projected simulation location on a line. The anisotropy is
addressed by affine transformation of the simulation space. The
conditioning is performed using kriging in a dual form to reduce
computational time. Modeling of multivariate systems is possible
with the linear model of coregionalization. The weighted random
factors are summed to obtain valid multivariate realizations. The
assimilation of the secondary gridded data is performed with
intrinsic cokriging, where the secondary data at a simulation
location and all primary data locations are used in the
conditioning. When the secondary data do not cover the entire
simulation domain, the secondary data is projected to the
simulation location and weighted appropriately to avoid edge
artifacts. The simulation of the nugget effect component is
expressed as a function…

▼ Three surveys (one oblate and two triaxial) of dynamical models of E6 elliptical galaxies were constructed in a flattened isothermal gravitational potential. These models represent a complete survey of all three dimensional shapes possible for these galaxies that are consistent with observations. Observational properties of the models are compared with observations of E6 ellipticals in order to constrain the shape of the galaxies. The models differ in the angular distribution of their density and potentials. A surface of constant potential of the oblate models is axisymmetric about its short axis whose length (q) is 0.75 times the length of the degenerate long axis. The triaxial models also have q = .075. The length of their intermediate axes are 0.8 (almost prolate models) or 0.9 (almost oblate models) times the length of their long axes. Thus, when a model is 'viewed' from its intermediate or degen- erate axis it appears as an E6 galaxy. The models were built using Schwarzschild's method of linear programming. The oblate models are axisymmetric. Consequently, the galaxy can be supported in two ways; a large velocity dispersion in the (omega) direction (cylindrical coordinates, (omega)('2) = x('2) + y('2)) or a large disper- sion in the (phi) direction. The triaxial models lack this symmetry and thus the spatially averaged second moments of the velocity in the direction of their principal axes is approximately the same for all models. Oblate models always have their axis of rotation along their minor axis and thus they have no minor axis rotation. Almost all tri- axial models can have minor axis rotation. Triaxial models can be constructed in either potential with their projected axes of rotation at any position angle with respect to the major axes of the galaxies. Almost oblate models can be constructed that only rotate along their minor axis. Almost prolate models can be constructed with only major axis rotation. The most surprising result is that in most models, the position angle of maximum observed rotation is not orthogonal to the position angle of zero rotation. Only one galaxy (NGC 4261) is know to have minor axis rotation. This indicates that either most elliptical galaxies are oblate or some process in their formation prohibits minor axis rotation.

▼ Computer and Information Science
Rather than being randomly wired together, the components of complex network systems are recently reported to represent a scale-free architecture, in which the node degree distribution follows power-law. While social networks are scale-free, it is natural to utilize their structural properties in some social network applications. As a result, this dissertation explores social network architectures, and in turn, leverages these architectures to facilitate some influence and information propagation applications. Social network architectures are analyzed in two different aspects. The first aspect focuses on the node degree snowballing effects (i.e., degree growth effects) in social networks, which is based on an age-sensitive preferential attachment model. The impact of the initial links is explored, in terms of accelerating the node degree snowballing effects. The second aspect focuses on Nested Scale-Free Architectures (NSFAs) for social networks. The scale-free architecture is a classic concept, which means that the node degree distribution follows the power-law distribution. `Nested' indicates that the scale-free architecture is preserved when low-degree nodes and their associated connections are iteratively removed. NSFA has a bounded hierarchy. Based on the social network structure, this dissertation explores two influence propagation applications for the Social Influence Maximization Problem (SIMP). The first application is a friend recommendation strategy with the perspective of social influence maximization. For the system provider, the objective is to recommend a fixed number of new friends to a given user, such that the given user can maximize his/her social influence through making new friends. This problem is proved to be NP-hard by reduction from the SIMP. A greedy friend recommendation algorithm with an approximation ratio of 1-e-1 is proposed. The second application studies the SIMP with the crowd influence, which is NP-hard, monotone, non-submodular, and inapproximable in general graphs. However, since user connections in Online Social Networks (OSNs) are not random, approximations can be obtained by leveraging the structural properties of OSNs. The modularity, denoted by Δ, is proposed to measure to what degree this problem violates the submodularity. Two approximation algorithms are proposed with ratios of \frac{1}{Δ+2} and 1-e-1/(Δ+1), respectively. Beside the influence propagation applications, this dissertation further explores three different information propagation applications. The first application is a social network quarantine strategy, which can eliminate epidemic outbreaks with minimal isolation costs. This problem is NP-hard. An approximation algorithm with a ratio of 2 is proposed through utilizing the problem properties of feasibility and minimality. The second application is a rating prediction scheme, called DynFluid, based on the fluid dynamics. DynFluid analogizes the rating reference among the users in OSNs to the…

▼ Today, Web services are applied in a variety of industries, and compose the building blocks of many Web-based and mobile applications. They are essential for the crossorganizational functional integration and data sharing across the network. On the one hand, how to construct a network in the Web service ecosystem to better organize them is the current research focus. On the other hand, Web service discovery is also a fundamentalforintegratingtherightservicesintothebusinessscenario. Inthiswork,weused a mathematical method for the evaluation of the social web application programming interface (API) network on the basis of data collected from ProgrammableWeb from the perspective of network science. We constructed two Web-API network models. One
scale-
free network is composed based on Barabasi-Albert model, the other used popularity-similarity optimization model which considers the similarity between nodes to enhance the performance of service discovery. We discussed the theoretical approach thatweusedtoconstructnetworkmodelsandalsopresentthedevelopprocedures. After the two Web-API network models were constructed, we evaluated the two network models, including nodes degree distribution, power-law, exponent, lower bound and preferential attachment. We discovered that Web-API network can suit the power-law distribution, and the performance of service discovery with them are better than typical means.

▼ In this dissertation we investigate the behavior of Wireless Sensor Networks (WSNs) from the degree distribution and evolution perspective. In specific, we focus on implementation of a scale-free degree distribution topology for energy efficient WSNs.; WSNs is an emerging technology that finds its applications in different areas such as environment monitoring, agricultural crop monitoring, forest fire monitoring, and hazardous chemical monitoring in war zones. This technology allows us to collect data without human presence or intervention. Energy conservation/efficiency is one of the major issues in prolonging the active life WSNs. Recently, many energy aware and fault tolerant topology control algorithms have been presented, but there is dearth of research focused on energy conservation/efficiency of WSNs.; Therefore, we study energy efficiency and fault-tolerance in WSNs from the degree distribution and evolution perspective. Self-organization observed in natural and biological systems has been directly linked to their degree distribution. It is widely known that scale-free distribution bestows robustness, fault-tolerance, and access efficiency to system. Fascinated by these properties, we propose two complex network theoretic self-organizing models for adaptive WSNs. In particular, we focus on adopting the Barabasi and Albert scale-free model to fit into the constraints and limitations of WSNs. We developed simulation models to conduct numerical experiments and network analysis. The main objective of studying these models is to find ways to reducing energy usage of each node and balancing the overall network energy disrupted by faulty communication among nodes.; The first model constructs the wireless sensor network relative to the degree (connectivity) and remaining energy of every individual node. We observed that it results in a scale-free network structure which has good fault tolerance properties in face of random node failures. The second model considers additional constraints on the maximum degree of each node as well as the energy consumption relative to degree changes. This gives more realistic results from a dynamical network perspective. It results in balanced network-wide energy consumption. The results show that networks constructed using the proposed approach have good properties for different centrality measures.; The outcomes of the presented research are beneficial to building WSN control models with greater self-organization properties which leads to optimal energy consumption.
