  1. The mid-Pleistocene transition as a transcritical bifurcation on a slow manifold - February 18m 2015

    16 Sep 2015 | Contributor(s):: Peter Ashwin

    The Quaternary Period has been characterized by a cyclical series of glaciations, which are attributed to the change in the insolation (incoming solar radiation) from changes in the Earth’s orbit around the Sun. The spectral power in the climate record is very different from that of the orbital...

  2. Periodic Fluctuations in deep water formation due to sea ice - Wednesday, January 21st/28th

    16 Sep 2015 | Contributor(s):: Raj Saha

    A simple dynamical model is used to demonstrate the possibility of stable and periodic variability in oceanic convection on a millennial timescale. Sea ice could act as a heat valve over the region of deep water formation in the North Atlantic, particularly during the last glacial period when sea...

  3. Realistic modeling and analysis of synchronization dynamics in power-grid networks

    08 May 2015 | | Contributor(s):: Takashi Nishikawa

    An imperative condition for the functioning of a power-grid network is that its power generators remain synchronized. Disturbances can prompt desynchronization, which is a process that has been involved in large power outages. In this talk I will first give a comparative review of three leading...

  4. Synchronization in power grid networks

    07 May 2015 | | Contributor(s):: Suman Acharyya

    This survey discusses Master Stability Function (MSF) analysis for determining stability of synchronization of coupled oscillators on network. In addition, we briefly discuss the derivation of the Swing equation that determine the dynamics of a node in power grid network, and...
