A Method for Analyzing Community Dynamics in Temporal Networks Applied to Emotional Recollection in fMRI Data
Temporal networks exhibit evolving patterns of connectivity, making the study of community organization a critical component of their analysis. Communities within a network are characterized by entities displaying higher interconnectivity within the community than outside it. In temporal networks, …

Complexity in Infinite Games on Graphs and Temporal Constraint Networks
… of algorithmic problems motivated by automated temporal planning and formal verification of reactive and finite state systems. Particularly, we shall focus on game theoretical methods in order to obtain improved complexity bounds and faster algorithms for the following models: Hyper Temporal …

Managing temporal uncertainty under limited communication : a formal model of tight and loose team coordination
… of autonomous robots will cooperate in large networks in order to achieve a common goal. These multi-agent systems will need to be able to execute cooperative temporal plans in the presence of temporal uncertainty and communication limitations. The duration of many planned activities will not …

The Interdependence of Scientists in the Era of Team Science: An Exploratory Study Using Temporal Network Analysis
… in the formation of collaborative relationships. Temporal network analysis at the mesoscopic level was used to study the collaboration dynamics of a specific research community, in this case the genomic research community emerging around GenBank, the international nucleotide sequence databank. The …

Understanding contagion spreading processes of cyber security threats through social networks
… studied and modelled as contagion processes on networks. Over the last decade, the unprecedented access to high resolution data about on/offline human interactions has shifted such studies from theoretical scholarly exercises to data-driven realistic models now used in a range of applications in …

Multiscale dynamics in honeybee societies
… in human society, and also characterize the temporal variation and resilience of foraging activity. In Part III, I describe a system to track individual honeybees and their interactions inside a two-dimensional observation hive with high spatiotemporal resolution. At the level of individual …

Modeling Urban Venue Dynamics through Spatio-Temporal Metrics and Complex Networks
… network science, modeling cities as connected networks of venues. Building upon a foundation of research in complex network theory, urban computing, and machine learning, we propose algorithms tailored for three computing tasks focused on modeling venue dynamics, characteristics, and trends. …

Dynamics and optimal control of information transmission in complex systems
… interactions affect information transmission on networks, and how these properties of the network may be optimally designed to achieve desired outcomes of information transmission. In Part I, spreading and consensus dynamics on time-varying networks are studied to explore how system parameters …

Robust planning and scheduling using column generation
… Controllability (SC). SC of Probabilistic Simple Temporal Networks (PSTN) involves finding a schedule to execute a sequence of actions that maximises the probability that all constraints are satisfied (robustness). Previous approaches to this problem assume independence of probabilistic durations. …

Decentralized Allocation of Tasks with Temporal and Precedence Constraints to a Team of Robots
… multi-robot task allocation problems with temporal and precedence constraints. To address this class of problems, we employ decentralized algorithms to find approximate solutions that minimize the maximum time needed to complete all tasks. To achieve decentralization, we use auction-based …

Topology of Social and Managerial Networks
… in recent years, organizational and man- agerial networks have reached high levels of intricacy. These are one of the many complex systems consisting of a large number of highly interconnected heterogeneous agents. The dominant paradigm in the representation of intricate relations between agents …

Human Behavior in Context: Analyzing Routines and Interactions Through Multi-Source Behavioral Data
… From analyzing collective behaviour with complex networks, to developing computational models for social science questions, researchers have come together to provide a more comprehensive understanding of how we act as individuals and as communities. In this context, we investigate human behaviour …
