How to design an effective and efficient load-frequency controller (LFC) for a multi-area interconnected power system to improve its power quality is a challenging issue. In order to deal with this issue, this paper presents a novel distributed fractional-order PID (DFOPID) control method for the load-frequency control of each area by using an adaptive population-based extremal optimization (APEO)...
Fall detection of the elderly is a major public health problem. Thus it has generated a wide range of applied research and prompted the development of telemedicine systems to enable the early diagnosis of fall conditions. This paper proposed a model that uses tri-axial acceleration sensor devices to detect an accidental fall and transmit the fall information to designed servers through wireless transmission...
Extremal optimization (EO) has been successfully applied to a variety of combinatorial optimization problems. However, the applications of EO to constrained optimization problems are relatively rare. This paper proposes a novel EO algorithm with adaptive constraints dealing techniques called EO-ACD for constrained optimization problems. The basic idea behind EO-ACD is the combination of real-coded...
Just like the crossover and mutation operations, selection operation plays an important role in controlling the performances of genetic algorithms (GA). This paper proposes binary coded genetic algorithms (BCGA) with different selection strategies, such as roulette-wheel, exponential, linear transformation, linear ranking selection, binary tournament selection, power-law based probability selection...
