Optimal Shape and Layout Design under Local Stress Constraint

Optimal Design of Geometrically Nonlinear Structures Under a Stability Constraint

This paper suggests an optimization-based methodology for the design of minimum weight structures with kinematic nonlinear behavior. Attention is focused on three-dimensional reticulated structures idealized with beam elements under proportional static loadings. The algorithm used for optimization is based on a classical optimality criterion approach using an active-set strategy for extreme lim...

Optimal Coding Subgraph Selection under Survivability Constraint

Nowadays communication networks have become an essential and inevitable part of human life. Hence, there is an ever-increasing need for expanding bandwidth, decreasing delay and data transfer costs. These needs necessitate the efficient use of network facilities. Network coding is a new paradigm that allows the intermediate nodes in a network to create new packets by combining the packets recei...

Design of optimal binary filters under joint multiresolution-envelope constraint

This paper examines binary filter design by jointly applying multiresolution design and envelope constraint. In multiresolution design, the value of the designed filter for a configuration is defined at a resolution sufficiently low to have observed the configuration. Preference is given to higher resolutions, but the number of training observations is taken into account. In envelope design, th...

A Computational Method for an Optimal Design Problem in Uniform Torsion Under Local Stress Constraints

In this paper we explore the possibilities from both a computational and numerical point of view of a relaxation method studied by the authors in previous work for related problems. The model problem considered in this paper for testing our computational method is the optimal design problem of finding the optimal distribution of two elastic isotropic materials that maximizes the torsional stiff...
