QoS Routing in Smart Grid.

AbstractSmart grid is an emerging technology which is able to control the power load
via price signaling. The communication between the power supplier and power
customers is a key issue in smart grid. Performance degradation like delay or
outage may cause significant impact on the stability of the pricing based
control and thus the reward of smart grid. Therefore, a QoS mechanism is
proposed for the communication system in smart grid, which incorporates the
derivation of QoS requirement and applies QoS routing in the communication
network.- Читать далее

Comparing tamed and compatible symplectic cones and cohomological properties of almost complex manifolds.

Subjects: Symplectic Geometry
AbstractWe introduce certain homology and cohomology subgroups for any almost complex
structure and study their pureness, fullness and duality properties. Motivated
by a question of Donaldson, we use these groups to relate J-tamed symplectic
cones and J-compatible symplectic cones over a large class of almost complex
manifolds, including all Kahler manifolds, almost Kahler 4-manifolds and
complex surfaces.Comparing tamed and compatible symplectic cones and cohomological properties of almost complex manifolds.
