A FRAMEWORK FOR NETWORK EVOLUTION
… il 2026, sfruttare questi dati è cruciale. La network science offre strumenti per analizzare sistemi complessi modellando nodi e archi. Ha applicazioni in diversi ambiti: nelle scienze sociali analizza social media, polarizzazione e migrazioni; in finanza studia stabilità dei mercati e frodi; …

Supply Chain Network Evolution: Demand-based Drivers of Interfirm Governance Evolution
… for a dynamic environment in a supply chain network (SCN) setting. This dissertation extends TCA and relational exchange to a dynamic, network environment. It uses the approach of building a simulation in order to study in detail the relationship between key exchange factors and the selection …

Simulating the Social Dynamics of Spatial Disparity Through Neighborhood Network Evolution
… choices about where to live and social network structure, and between neighborhood and community networks. Following an overview of enabling theories and developments, I develop a spatial dynamic simulation model that enables virtual experimentation with both friendship and location …

Numerical modeling of groundwater-driven stream network evolution in low-relief areas
Fluvial channel networks are observed to grow in unchannelized areas of low relief despite the low potential energy for erosion in these areas of low slope. Under these low slope conditions significant channel growth only occurs when water is collected and flows as concentrated discharge in …

Computational modelling of polymer network formation
… most relevant properties of the forming polymer network in step-growth polymerisation. As model systems, epoxy-amine copolymers were used, with different monomer functionalities of the hardener molecules. Using numerical simulations on a graph, which is essentially a simulated random process …

Economic and policy analysis on high-speed rail and interactions with air transport
… further study the Chinese HSR by reviewing its network evolution and projecting its future development. Second, we conduct a macroeconomic comparison between HSR and Low-cost carrier in Japan and Western Europe. The findings reveal that Japan and Europe have both promoted HSR as the government …

An Evolutionary Computation Model of Intracellular Signaling Networks
We use evolutionary computation (EC) methods to simulate the evolution of a particular class of intracellular signaling networks. This class of signaling networks mimics the cellular state transition (or mode switch) in a living cell in response to a specific number of prerequisites. Two different …

Modeling and Analysis of Interaction Networks in Ecological Systems
Understanding how networks form and evolve is an important question in many fields such as ecology, epidemiology, economics, and sociology. Studying the mechanisms of network formation can yield insight into which factors are involved in edge formation and network growth. This thesis explores …

The early history and emergence of molecular functions and modular scale-free network behavior
… Here we trace domain history onto a bipartite network of elementary functional loop (EFL) sequences and domain structures defined at the fold superfamily (FSF) level of Structural Classification of Proteins (SCOP). The resulting ‘elementary functionome’ network and its EFL and FSF graph …

In Silico Evolution of Oscillating Mass-Action Chemical Reaction Networks
Evolutionary algorithms, a class of optimization techniques inspired by biological evolution,have emerged as powerful tools for the optimization of complex systems, including the evolution of mass-action chemical reaction networks. This dissertation explores the application of evolutionary …

Investigating the evolution of diversity and complexity of Prokaryotic gene regulatory networks using in silico models
There is much debate about the evolutionary origins of diversity and many complex gene regulatory network features, such as global regulation. Using novel in silico models the evolutionary origins of complex features, heterogeneity and the role of stochastic molecular processes in gene regulatory …

Fairness in Social Networks
<p>In professional and other social settings, networks play an important role in people's lives. The communication between individuals and their positions in the network, may have a large impact on many aspects of their lives.In this work, I evaluate fairness from different …

Temporal Evolution of Scholarly Communication
The general topic of the dissertation is citation network dynamics. I employ two perspectives on the evolution of citation networks in order to extend our understanding of the context of scientific progress. The first two sections develop a general mechanism to predict how papers gain attention and …

Assessing guerrilla doctrine: battlefield lessons on network structure and multi-front insurgency
… hybrid between guerrilla hierarchies and networks, positing optimal organizational structure as a function of operational environment. Logistical capacity, tactics, target set, and military classification are in turn best determined by organizational structure. An otherwise unobserved …

Internet 0
… and in disconnected groups. Similar to computer network evolution where the Internet was used to bridge together heterogeneous computer systems, I present Internet 0 (I0) as a framework to bridge together heterogeneous devices via Internet Protocols--therefore in a manner that is compatible with …

Demonstration of an Effective 4G LTE Network Simulator to Analyze Performance and Ensure Reliable Communication
… service provider. Though the 3GPP’s Long Term Evolution (LTE) has been successful to mitigate most of the challenges, there arises a need to foresee the cellular network evolution considering various factors like increase in number of users in a particular area, urbanization etc., and …

Cooperative assembly confers regulatory specificity and promotes evolution
… a simple, generalizable means for building evolutionarily robust gene circuits that can be scaled to a wide range of host organisms and applications. Assemblies of cooperative TRs have also been found to facilitate the gene regulatory network rewiring that drives evolution. TRs that arise in …

Bio-physical controls on tidal network geomorphology
Looking over a tidal wetland, the tidal network characterised by its intricate system of bifurcating, blind-ended tidal courses clearly stands out from the overall landscape. This tidal landform exerts a fundamental control on the morphology and ecology within the tidal environment. With today’s …

Knowledge Networks in Emerging ICT Regional Innovation Systems: An Explorative Study of the Knowledge Network of Trentino ICT Innovation System
… makers, only during the last decade social networks were applied in the fields of innovation and regional economics. The majority of the existing empirical studies on networks adopt a static point of view, representing a regional knowledge network at a certain point in time, while there are …

Network reliability estimation
Computing the reliability of a network is a #P-complete problem, therefore estimation by means of simulation often becomes a favourable choice. In modern communication networks, link failure probabilities are usually small and hence network failures become rare events. This poses a challenge to …
