Parametric ordering of complex systems [PDF]
, 1993 Cellular automata (CA) dynamics are ordered in terms of two global parameters, computable {\sl a priori} from the description of rules. While one of them (activity) has been used before, the second one is new; it estimates the average sensitivity of ...

Topic detection with recursive consensus clustering and semantic enrichment
Humanities & Social Sciences Communications, 2023 Extracting meaningful information from short texts like tweets has proved to be a challenging task. Literature on topic detection focuses mostly on methods that try to guess the plausible words that describe topics whose number has been decided in ...

Complexity and fragility in system of systems
International Journal of System of Systems Engineering, 2016 SoS are an ensemble of complex systems, which have the potential for an extraordinary amount of structural complexity, even temporarily, as a result of interconnections and couplings that can vary in strength. Because of this, SoS can be vulnerable to sudden catastrophic collapse as a result of small and insignificant partial functionality losses in ...

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada
Population Ecology, EarlyView.We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

What Makes Complex Systems Complex? [PDF]
, 2018 This paper explores some of the factors that make complex systems complex. We first examine the history of complex systems. It was Aristotle’s insight that how elements are joined together helps determine the properties of the resulting whole. We find (a)

The Competing Two-Strain SIS Pairwise Approximation Model With Infection Age
IEEE Access, 2019 This paper studies a two-strain SIS pairwise approximation model with a competing mechanism and non-Markovian recovery process in which the recovery rate depends on infection age.

Freight Time and Cost Optimization in Complex Logistics Networks
Complexity, 2020 The complexity of providing timely and cost-effective distribution of finished goods from industrial facilities to customers makes effective operational coordination difficult, yet effectiveness is crucial for maintaining customer service levels and ...

Narrativity in Complex Systems [PDF]
, 2021 AbstractHumans use narrative for making sense of their environment. In this chapter we ask if, and if so how and to what extent, our narrative mind can help us deal scientifically with complexity. In order to answer this question, and to show what this means for education, we discuss fundamental aspects of narrative understanding of dynamical systems ...
