Automatic circle detection in digital images has received considerable attention over the last years in computer vision as several efforts have aimed for an optimal circle detector. This paper presents an algorithm for automatic detection of circular shapes that considers the overall process as an optimization problem. The approach is based on the Harmony Search Algorithm (HSA), a derivative fr...

Proposing a new precise price forecasting method is still challenging task as electricity signals generally exhibit various complex features. In this paper, approach for called hybrid local general regression neural network, and harmony search algorithm (LGRNN-HSA) proposed. The proposed LGRNN-HSA developed by combining the coordinate delay (CD) method, paradigm, network (GRNN) (HSA). CD employ...

One of the serious reasons of death among women is breast cancer. Early diagnosis can help to women’s quality of life. In this context, mammography images have a most significant effectiveness. In fact, they are known as the main test used for screening and early diagnosis. Recently, computer aided mass detection techniques was an active field of research and some of these studies showed a prom...

This paper proposes an optimal design for control and overspeed protection in Gas turbine by means of reliability redundancy optimization. In general form, the problem is consisting of four control valves (stop valves), as a subsystem, each of them has the same components with reliability, weight and other parameters. The problem objective is to find a maximum reliability for total system in or...

The main aim of the present study is to propose a modified harmony search (MHS) algorithm for size and shape optimization of structures. The standard harmony search (HS) algorithm is conceptualized using the musical process of searching for a perfect state of the harmony. It uses a stochastic random search instead of a gradient search. The proposed MHS algorithm is designed based on elitism. In...

Individually Network reconfiguration or Capacitor control perform well in minimizing power loss and improving voltage profile of the distribution system. But for heavy reactive power loads network reconfiguration and for heavy active power loads capacitor placement can not effectively reduce power loss and enhance voltage profiles in the system. In this paper, an hybrid approach that combine ne...

Many search-based algorithms have been successfully applied in several software engineering activities. Genetic (GAs) are the most used scientific domains by scholars to solve testing problems. They imitate theory of natural selection and evolution. The harmony search algorithm (HSA) is one recent last years. It imitates behavior a musician find best harmony. Scholars estimated similarities dif...
