Kinematic Basis of Emergent Energetics of Complex Dynamics
Stochastic kinematic description of a complex dynamics is shown to dictate an
energetic and thermodynamic structure. An energy function emerges
as the limit of the generalized, nonequilibrium free energy of a Markovian
dynamics with vanishing fluctuations. In terms of the and its
orthogonal field , a general vector field
can be decomposed into , where
.
The matrix and scalar , two additional characteristics to the
alone, represent the local geometry and density of states intrinsic to
the statistical motion in the state space at . and
are interpreted as the emergent energy and degeneracy of the motion, with an
energy balance equation ,
reflecting the geometrical . The
partition function employed in statistical mechanics and J. W. Gibbs' method of
ensemble change naturally arise; a fluctuation-dissipation theorem is
established via the two leading-order asymptotics of entropy production as
. The present theory provides a mathematical basis for P. W.

A Concentric-based Sleep Scheduling Scheme for Wireless Sensor Networks
[[abstract]]In Wireless Sensor Networks (WSNs), how to
extend the lifetime is an important issue. Our research
uses Sleeping Scheduling scheme which divides the
network into many concentric layers and rotates sensors in
different odd and even layers to sleep. By our scheme, we
can balance the power consumption among all sensors and
reduce power and transmission load of sensors near sink.
Our research use Transmit Power Control (TPC)
technique to control topology and divide concentric layers,
and use the topology to transmit packets to sink. Finally,
the performance of our scheme is better than other
Sleeping Scheduling schemes in the simulations.[[sponsorship]]Tamkang University[[incitationindex]]EI[[conferencetype]]åé[[conferencetkucampus]]å°åæ ¡å[[conferencedate]]20150902~20150903[[booktype]]é»åÂç[[iscallforpapers]]Y[[conferencelocation]]Taipei, Taiwa
