Conservation laws for a coupled variable-coefficient modified Korteweg-de Vries system in a two-layer fluid model
(Elsevier Science BvAmsterdamHolanda, 2013)
Nonlinear Self-adjoint Classification Of A Burgers-kdv Family Of Equations

A lattice gauge theory for fields in the adjoint representation
(1984-12-01)
We present a mathematical formulation for a gauge theory for fields in the adjoint representation of SU n, where the fields are general differential forms living on the lattice objects, like sites, links, plaquettes, etc. ...
Gravity wave drag estimation from global analyses using variational data assimilation principles. I: Theory and implementation
(Wiley, 2005-07)
A novel technique to estimate gravity wave drag from global-scale analyses is presented. It is based on the principles of four-dimensional variational data assimilation, using a dynamical model of the middle atmosphere and ...
Optimal attitude corrections for cylindrical spacecraft
(Elsevier B.V., 2003-01-01)
A first order analytical model for optimal small amplitude attitude maneuvers of spacecraft with cylindrical symmetry in an elliptical orbits is presented. The optimization problem is formulated as a Mayer problem with the ...
A comnutative diagram among discrete and continuous Neumann boundary optimal control problems
(Pushpa Publishing House, 2014-12)
We consider a bounded domain nR⊂Ω whose regular boundary 21ΓΓ=Ω∂=Γ∪ consists of the union of two disjoint portions 1Γ and 2Γ with positive measures. The convergence of a family of continuous Neumann boundary mixed elliptic ...
A linear solution for the artificial satellite's attitude optimal control
(1999-12-01)
A first order analytical model for a general problem of artificial satellite's attitude corrections maneuvers submitted to gravity gradient torque is presented in this paper. It is assumed that the satellite is a rigid ...
Existence, uniqueness and convergence of simultaneous distributed-boundary optimal control problems
(Polish Acad Sciences Systems Research Inst, 2015-01)
We consider a steady-state heat conduction problem P for the Poisson equation with mixed boundary conditions in a bounded multidimensional domain Ω. We also consider a family of problems Pα for the same Poisson equation ...
The seasonal cycle of gravity wave drag in the middle atmosphere
(American Meteorological Society, 2008-09)
Using a variational technique, middle atmosphere gravity wave drag (GWD) is estimated from Met Office middle atmosphere analyses for the year 2002. The technique employs an adjoint model of a middle atmosphere dynamical ...
