Compressing the image causes less memory to be used store images. images increases transmission speed of compressed in network. Vector quantization (VQ) is one compression methods. The challenge vector method for non-optimization codebooks. Codebook optimization quality and reduces volume Various methods swarm intelligence meta-heuristics are improve algorithm, but using meta-heuristic based on...

assigning facilities to locations is one of the important problems, which significantly is influence in transportation cost reduction. in this study, we solve quadratic assignment problem (qap), using a meta-heuristic algorithm with deterministic tasks and equality in facilities and location number. it should be noted that any facility must be assign to only one location. in this paper, first o...

Texture image classification is an important topic in many applications in machine vision and image analysis. Texture feature extracted from the original texture image by using "Tuned" mask is one of the simplest and most effective methods. However, hill climbing based training methods could not acquire the satisfying mask at a time; on the other hand, some commonly used evolutionary algorithms...

Keeping the bus voltage within acceptable limits depends on dispatching reactive power. Power quality improves as a result of creating an effective power flow system, which also helps to reduce loss. Therefore, optimal dispatch (ORPD) studies aim at designing appropriate system configurations enable reliable operation systems. Establishment such configuration is handled through control variable...

The power industry experiences revolution known as "Power Industry Structure Renewal" mainly due to increasing progresses in science and technology which will result in a gradual change in methods of communication with energy tools. Part of the revolution is the application of small generation units in power generation; units with lower generation volume capacity, and cost compared to the enorm...
