Conditional nonlinear optimal perturbation and its applications
Conditional nonlinear optimal perturbation applications
2009/11/12
Conditional nonlinear optimal perturbation (CNOP) is proposed to study the predictability of numerical weather and climate prediction. A simple coupled ocean-atmosphere model for ENSO is adopted as an...
A Perturbation Based Model of Heat-Induced Suppression of River Ice
Perturbation Based Model Heat-Induced Suppression River Ice
2009/10/27
The study of the thermal response of ice covered streams to an effluent of high
temperature, or of fast moving water, has been of considerable interest to those
concerned with hydraulic systems, env...

Exact solutions for systems of Volterra integral equations of the first kind by homotopy perturbation method
Systems of Volterra integral equations Homotopy perturbation method
2010/9/14
In this article, the homotopy perturbation method is proposed to solve systems of Volterra integral equations of the first kind. Theoretical proposes are presented briefly, so that this paper can be r...

2010/9/14
In this paper applies the He’s homotopy perturbation method (HPM)to obtaining solution of nonlinear dynamic model.The nonlinear considered model is the Gas Dynamics equation.
WCDMA uplink system capacity: A singular perturbation approach
Singular W-CDMA singular perturbation Lyapunov
2010/9/13
We consider a WCDMA system with two types of calls: real time (RT) calls that have dedicated resources, and data on real time (BE) calls (i.e. best effort) that share system capacity. We consider rese...
Perturbation of the European free troposphere aerosol by North American forest fire plumes during the ICARTT-ITOP experiment in summer 2004
European free troposphere aerosol North American forest fire ICARTT-ITOP
2008/12/22
During the ICARTT-ITOP Experiment in summer 2004 plumes from large wildfires in North America were transported to Central Europe at 3–8 km altitude above sea level (a.s.l.). These plumes were studied...
An Adjoint Method for Obtaining the Most Rapidly Growing Perturbation to Oceanic Flows
oceanic flows quasigeostrophic model Most Rapidly Growing Perturbation
2008/12/22
This work explores the formation and growth of waves on oceanic flows using a quasigeostrophic model. In particular, we consider flow regimes consisting of zonal oceanic jets, similar in fact to the w...
Rapid Perturbation Growth on Spatially and Temporally Varying Oceanic Flows Determined Using an Adjoint Method：Application to the Gulf Stream
Rapid Perturbation Growth Temporally Varying Oceanic Flows Gulf Stream
2008/12/19
The stability of the Gulf Stream flow predicted by a nonlinear quasigeostrophic model is examined by employing an iterative method, which uses both the tangent linear equations and the adjoint tangent...
The Effect of Current-Induced Stress Perturbation On Baroclinic Rossby Waves in a Continuously Stratified Model
Current-Induced Stress Perturbation Baroclinic Rossby Waves Continuously Stratified Model
2008/12/11
A shear stress at the air–sea interface is induced by the presence of surface currents. In the case of isotropic wind, a quadratic stress law leads to a stress curl proportional to and opposing the su...
A perturbation of m-order derivations on Banach algebras
m-order derivation approximate m-order derivation stability
2010/2/25
Let \A be a unital Banach algebra and let m, 1 \leq m \leq 4, be an integer. If f: \A \to \A is an approximate m-order derivation in the sense of Hyers-Ulam-Rassias, then f: \A \to \A is an exact m-or...
