Optimal Prediction for Moment Models: Crescendo Diffusion and Reordered Equations
A direct numerical solution of the radiative transfer equation or any kinetic equation is typically expensive, since the radiative intensity depends on time, space and direction. An expansion in the direction variables yields an equivalent system of infinitely many moments. A fundamental problem is how to truncate the system. Various closures have been presented in the literature. We want to st...
متن کاملOPTIMAL DESIGN OF COLUMNS FOR AN INTERMEDIATE MOMENT FRAME UNDER UNIAXIAL MOMENT AND AXIAL LOADS
The present study addresses optimal design of reinforced concrete (RC) columns based on equivalent equations considering deformability regulations of ACI318-14 under axial force and uniaxial bending moment. This study contrary to common approaches working with trial and error approach in design, at first presents an exact solution for intensity of longitudinal reinforcement in column section by...
متن کاملOptimal Prediction for Hamiltonian PartialDifferential Equations
Optimal prediction methods compensate for a lack of resolution in the numerical solution of time-dependent differential equations through the use of prior statistical information. We present a new derivation of the basic methodology, show that field-theoretical perturbation theory provides a useful device for dealing with quasi-linear problems, and provide a nonlinear example that illuminates t...
متن کاملLsign Reordered Lsign Reordered
LSign 18] is an elegant domain for analyzing constraint logic programming languages over linear real constraints. Its key conceptual ideas are the abstraction of linear constraints by replacing coeecients by their signs and the use of annotations for preserving multiplicity information on the constraints. Unfortunately, the ordering of abstract constraint stores given in 18] does not capture th...
متن کاملOptimal Control and Numerical Adaptivity for Advection–diffusion Equations
We propose a general approach for the numerical approximation of optimal control problems governed by a linear advection–diffusion equation, based on a stabilization method applied to the Lagrangian functional, rather than stabilizing the state and adjoint equations separately. This approach yields a coherently stabilized control problem. Besides, it allows a straightforward a posteriori error ...
