Presented in this paper is design of the new CMOS circuits to implement Min and Max operators. This work is based on analog advantages such as low die area, high DC range and simplicity which are added to the fuzzy system advantages. For implementing this idea, new current mode circuits are proposed which based on Wilson current mirrors. We used the one of them (min circuit) in implementing inference...
This paper provides an overview on immune clone selection algorithm for the automated design and optimization of fuzzy logic controller. A new optimization method for fuzzy logic controller design is proposed. The membership functions of input and output variables are defined by six parameters, which are adjusted to maximize the performance index of the controller by using immune clone selection algorithm...
In behavior based robotics, development of behavior coordination method is very important. Fuzzy behavior coordination (FBC) can be used here, but it still have weaknesses, because it can result in slow robot movement, too long time to reach the target and fail to avoid trap. In this paper, modification of FBC, by combining it with subsumption architecture, is proposed to overcome those weaknesses...
Most surgical operation need an anesthetic agent to administer for obtaining a local or general anesthetic condition of a patient. General anesthesia affects the brain cells and puts the patient unconscious, pain free, immobile and free from memory. It is a challenge to the anesthetist to administer a proper dose of anesthetic agent for required depth of anesthesia. In most situations it is a decision...
Congestion control mechanism such as random early detect (RED) allows more efficient usage of network resources. RED uses static thresholds (high and low) in combating congestion. However, as network becomes more dynamic with the introduction of multimedia and real time application, this ldquostaticrdquo approach becomes inefficient. This paper proposed a dynamic RED mechanism, namely, fuzzy active...
