Design of bi-metallic devices based on the topological derivative concept
(Pergamon-Elsevier Science Ltd., 2015-01)
In this work the topological derivative concept is applied in the context of topology design of thermo-mechanical devices, where the linear elasticity system (modeled by the Navier equation) is coupled with the steady-state ...
Piezoresistive device optimization using topological derivative concepts
(Springer, 2014-10)
A piezoresistive sensor is composed of a piezoresistive membrane attached to a flexible plate. The piezoresistive material is anisotropic, and its electrical properties change when subjected to mechanical stresses. In this ...
Design topologies optimization in GPON networks based on population densities using k-means clustering algorithm
(IEEEMéxico, 2019)
Most studies for implementation of access networks are generally focused on countries where their areas have high population density, this optimization seeks to provide solutions in countries and cities with a similar ...
