A fuzzy logic toolkit has been developed for the formal specification language Z. It permits the incorporation of fuzzy concepts into the language while retaining the precision of any Z specification. The toolkit provides the necessary operators, measures and modifiers for the definition and manipulation of fuzzy sets and relations. This paper illustrates how the toolkit can be used to specify ...
in this study, a simple, rapid and selective method was developed for the determination of dexamethasone. the proposed method is based on inhibitory effect of dexamethasone on the oxidation of orange-g by bromate in sulfuric acid media. the reaction was followed spectrophotometrically at 478.5 nm (?max). under optimum experimental conditions, (72.6 ?mol l-1 of orange-g, 0.76 mol l-1 of h2so4, 0...
abstract according to increase in electricity consumption in one hand and power systemsreliability importance in another , fault location detection techniqueshave beenrecentlytaken to consideration. an algorithm based on collected data from both transmission line endsproposed in this thesis. in order to reducecapacitance effects of transmission line, distributed parametersof transmission line...
Centroid based clustering approaches, such as k-means, are relatively fast but inaccurate for arbitrary shape clusters. Fuzzy c-means with Mahalanobis distance can accurately identify clusters if data set be modelled by a mixture of Gaussian distributions. However, they require number apriori and bad initialization cause poor results. Density methods, DBSCAN, overcome these disadvantages. may p...
abstract biometric access control is an automatic system that intelligently provides the access of special actions to predefined individuals. it may use one or more unique features of humans, like fingerprint, iris, gesture, 2d and 3d face images. 2d face image is one of the important features with useful and reliable information for recognition of individuals and systems based on this ...
The objective of this study was to develop a Fuzzy Rule-Based System (FRBS) for the mathematically modeling irrigation level effect on beet cultivars ( Beta vulgaris L.). From an agronomic experiment carried out in protected environment (greenhouse), it defined as input variables, each cultivar, levels (depths 25, 40, 55, 70, 85, and 100% ETc), which ETc is crop evapotranspiration [mm d−1], whi...
Lots of problems that contain uncertainty arise in this world. Fuzzy logic is one the methods created to analyze systems these uncertainties. In study, author uses Mamdani method or often also known as Min-Max which an application fuzzy method. The purpose study was determine amount tofu production at UD. Eko Jaya Pasuruan by using MinMax (Mamdani) data used number requests and product inventor...
The Greenfield-Chiclana Collapsing Defuzzifier comes in many variants, depending on the order of slice collapse. The accuracy of the fundamental variants of forward, backward, inward and outward, and the composite variants of forward-backward and outward right-left is compared experimentally for the discretised interval type-2 fuzzy set. Keywords— Centroid, Collapsing, Defuzzification, Interval...
All the real systems exhibits non-linear nature, conventional controllers are not always able to provide good and accurate results. Fuzzy Logic Control is used to obtain better response. A model for simulation is designed and all the assumptions are made before the development of the model. An attempt has been made to analyze the efficiency of a fuzzy controller over a conventional PID controll...
