On a Galerkin discretization of 4th order in space and time applied to the heat equation
We present a new time discretization scheme based on the continuous Galerkin Petrov method of polynomial order 3 (cGP(3)-method) which is combined with a reduced numerical time integration (3-point Gauß-Lobatto formula). The solution of the new approach can be computed from the solution of the lower order cGP(2)-method, which requires to solve a coupled 2 × 2 block system on each time interval,...
متن کاملThird order convergent time discretization for parabolic optimal control problems with control constraints
We consider a discretization and the corresponding error analysis for a linear quadratic parabolic optimal control problem with box constraints on the timedependent control variable. For such problems one can show that a time-discrete solution with second order convergence can be obtained by a first order discontinuous Galerkin time discretization for the state variable and either the variation...
متن کاملA third-order multistep time discretization for a Chebyshev tau spectral method
A time discretization scheme based on the third-order backward difference formula has been embedded into a Chebyshev tau spectral method for the Navier-Stokes equations. The time discretization is a variant of the second-order backward scheme proposed by Krasnov et al. (J. Fluid Mech., 2008). Highresolution direct numerical simulations of turbulent incompressible channel flow have been performe...
متن کاملA Multi-objective optimization model for project scheduling with time-varying resource requirements and capacities
Proper and realistic scheduling is an important factor of success for every project. In reality, project scheduling often involves several objectives that must be realized simultaneously, and faces numerous uncertainties that may undermine the integrity of the devised schedule. Thus, the manner of dealing with such uncertainties is of particular importance for effective planning. A realistic sc...
متن کاملDecomposition of Third Order Linear Time-Varying System into its Second and First Order Commutative Pairs
Decomposition is a common tool for synthesis of many physical systems. It is also used for analyzing large scale systems which then known as fearing and reconstruction. On the other hand, commutativity of cascade connected systems have gained a grate deal of interest and its possible benefits have been pointed out in the literature. In this paper, the necessary and sufficient conditions for dec...
