In this article we applied modified binary particle swarm optimization algorithm for solving the sensor placement in distributed sensor networks. PSO is a real value algorithm, and the discrete PSO is proposed to be adapted to discrete binary space. In the distributed sensor networks, the sensor placement is NP-complete for arbitrary sensor fields and it is one of the most important issues in the...
The selection of threshold is one the general methods in image segmentation, but often the selection of the optimal value for threshold is a challenge for researchers. In this paper we proposed a fast and optimal method for selection of good enough threshold value based on Particle Swarm Optimization algorithms (PSOa). To achieve the fast speed in the proposed method, five types of PSO algorithms...
Adaptive Multi-Rate (AMR) codec was standardized for GSM in 1999. AMR offers substantial improvement over previous GSM speech codecs in error robustness by adapting speech and channel coding depending on channel conditions. The Adaptive Multi-Rate speech codec is adopted as a standard for IMT-2000 by ETSI and 3GPP and consists of eight source codecs with bit rates from 4.75 to 12.2 kbit/s. In this...
