Reducing Spatial Sampling in Long-Term Groundwater Monitoring Networks Using Ant Colony Optimization

Groundwater long-term monitoring (LTM) is required to assess human health and environmental risk of residual contaminants after active groundwater remediation activities are completed. However, LTM can be costly because of the large number of sampling locations that exist at a site from previous site characterization and remediation activities. The cost of LTM may be reduced by identifying redu...

Optimal Groundwater Sampling Network Design through Ant Colony Optimization

Groundwater long-term monitoring (LTM) is required to assess the performance of groundwater remediation and human being health risk at post-closure sites where groundwater contaminants are still present. The large number of sampling locations, number of constituents to be monitored, and the frequency of the sampling make the LTM costly, especially since LTM may be required over several decades....

Noncooperative Optimization of Space-Time Signals in Ad hoc Networks

Recent results on noncooperative space-time waveform optimization for Ad hoc networks are first reviewed. The optimization criterion is sum power minimization under a QoS constraint (decoupled capacity.) Noncooperative iterative minimum mean-square (IMMSE) algorithms are advocated here as a pragmatic solution to the QoS constrained optimization problem. Connections between IMMSE, time-reversal ...

OPTIMIZATION OF SKELETAL STRUCTURES USING IMPROVED GENETIC ALGORITHM BASED ON PROPOSED SAMPLING SEARCH SPACE IDEA

In this article, by Partitioning of designing space, optimization speed is tried to be increased by GA. To this end, designing space search is done in two steps which are global search and local search. To achieve this goal, according to meshing in FEM, firstly, the list of sections is divided to specific subsets. Then, intermediate member of each subset, as representative of subset, is defined...
