Preconditioned Conjugate Gradient Algorithms for Nonconvex Problems with Box Constraints,imization, Vol. 8, 532–560, 1998]. We believe that the preconditioned conjugate gradient algorithm gives more flexibility in achieving balance between the computing time and the number of function evaluations in comparison to a limited memory BFGS algorithm. The numerical results show that the proposed method is competitive to L-BFGS-B procedure.

On the Efficiency of the ,-Subgradient Methods Over Nonlinearly Constrained Networks,ts. Such Lagrangian function includes the side constraints. In order to evaluate the efficiency of these .-subgradient methods some of them have been implemented and their performance computationally compared with that of other well-known codes. The results are encouraging.

The Legacy of Camillo Possio to Unsteady Aerodynamics,in flutter and unsteady aerodynamic research, and the challenges and problems like high-speed flight that arose in aircraft development at that time. Possio’s first publications on gas dynamic and supersonic problems are reviewed. The main focus is on the 1938 report on unsteady subsonic compressibl

The Possio Integral Equation of Aeroelasticity: A Modern View,ng ‘flutter’. Currently all the effort is completely computational: wedding Lagrangian NASTRAN codes to the CFD codes to produce ‘Time Marching’ solutions. While they have the ability to handle nonlinear complex geometry structures as well as viscous flow, they are based approximation of the p.d.e.

Analysis of a PDE Model for Sandpile Growth,o a bounded domain Ω ⊂ R.. The mathematical description of the table problem, at an equilibrium configuration, can be reduced to a boundary value problem for a system of partial differential equations. The analysis of such a system, also connected with other mathematical models such as the Monge-Kan
