Reachability in Linear Dynamical Systems [PDF]
, 2008 Dynamical systems allow to modelize various phenomena or processes by only describing their local behaviour. It is however useful to understand the behaviour in a more global way. Checking the reachability of a point for example is a fundamental problem.

Complexity and Dynamical Depth
Information, 2014 We argue that a critical difference distinguishing machines from organisms and computers from brains is not complexity in a structural sense, but a difference in dynamical organization that is not well accounted for by current complexity measures.

Linear Systems and Discontinuous Dynamics [PDF]
, 1997 A dynamical system may be called discontinuous if it is subject to abrupt changes in its dynamic characteristics. Such changes may be induced either externally (“time events”) or internally (“state events”). Here we discuss so-called linear complementarity systems.

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 ...

Network topology drives population temporal variability in experimental habitat networks
Population Ecology, EarlyView.Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

On linear dynamic complementary systems [PDF]
IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 1999 Summary: A new method is proposed to solve dynamic linear complementary systems. To this class of systems belong all electrical piecewise linear dynamic networks. The method uses numerical integration methods to transform the original problem into the static standard linear complementary problem that needs to be solved for each time step period.

Population Ecology, EarlyView.We investigate the seasonal dynamics of two freshwater snails, Biomphalaria straminea and Melanoides tuberculata, in artificial reservoirs of the Brazilian semiarid region. Despite regulated hydrology, B. straminea exhibited strong seasonal fluctuations associated with dry periods, while M. tuberculata maintained stable populations throughout the year,

Dynamical System Analysis of Interacting Hessence Dark Energy in f(T) Gravity
Advances in High Energy Physics, 2017 We have carried out dynamical system analysis of hessence field coupling with dark matter in f(T) gravity. We have analysed the critical points due to autonomous system. The resulting autonomous system is nonlinear.

Antagonistic interactions can stabilise fixed points in heterogeneous linear dynamical systems
SciPost Physics, 2023 We analyse the stability of large, linear dynamical systems of variables that interact through a fully connected random matrix and have inhomogeneous growth rates.

Model Identification and Data Analysis, 2018 The term dynamical system refers to the (differential) equations governing the timevarying behavior of some physical system. A system consisting of discrete units, e.g., the vibrations of a mass–spring chain, a more general structure, or an electrical ...
