A transient stability assessment method using post-fault trajectories

Maher Kayal, Theodoros Kyriakidis, Guillaume Olivier Lanz

Transient Stability Assessment (TSA) is the process in which the stability of a system is characterized qualitatively or quantitatively. The TSA algorithm presented in this paper is derived from the well-established Single Machine Equivalent (SIME) method ...

Weak second order explicit stabilized methods for stiff stochastic differential equations

Assyr Abdulle, Gilles Vilmart

We introduce a new family of explicit integrators for stiff Ito stochastic differential equations (SDEs) of weak order two. These numerical methods belong to the class of one-step stabilized methods with extended stability domains and do not suffer from th ...

On species persistence-time distributions

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Samir Suweis, Amos Maritan

We present new theoretical and empirical results on the probability distributions of species persistence times in natural ecosystems. Persistence times, defined as the timespans occurring between species' colonization and local extinction in a given geogra ...

An exactly solvable coarse-grained model for species diversity

Andrea Rinaldo, Samir Suweis, Amos Maritan

We present novel analytical results concerning ecosystem species diversity that stem from a proposed coarse-grained neutral model based on birth-death processes. The relevance of the problem lies in the urgency for understanding and synthesizing both theor ...

Influence of confinement on a two-dimensional wake

François Gallaire, Luca Biancofiore

The spatio-temporal development of an incompressible two-dimensional viscous wake flow confined by two flat slipping plates is investigated by means of direct numerical simulation (DNS), using a spectral Chebyshev multi-domain method. The limit between uns ...

Spatial effects on species persistence and implications for biodiversity

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Samir Suweis, Amos Maritan

Natural ecosystems are characterized by striking diversity of form and functions and yet exhibit deep symmetries emerging across scales of space, time, and organizational complexity. Species-area relationships and species-abundance distributions are exampl ...

Measurement and Theoretical Modeling of the Damping Rate of Medium-N Toroidal Alfven Eigenmodes in JET

Ambrogio Fasoli, Duccio Testa, Patrick Blanchard, Theodoros Panis, Nicolas Mellet

This paper reports on the results of recent experiments performed on the JET tokamak on Alfven Eigenmodes (AEs) with toroidal mode number (n) in the range |n|=3-15. The stability properties of these medium-n AEs are investigated experimentally using a set ...

Recent JET Experiments on Alfvén Eigenmodes with Intermediate Toroidal Mode Numbers: Measurements and Modelling with the TAEFL code

Ambrogio Fasoli, Duccio Testa, Patrick Blanchard, Theodoros Panis

This paper reports the results of recent experiments performed on the JET tokamak on Alfven eigenmodes (AEs) with toroidal mode number (n) in the range n=3—15. The stability properties of these medium-n AEs are investigated experimentally using a new set o ...
