“…They are particularly useful in system modeling, such as in implementing complex mappings and system identification. AI systems comprise areas such as expert systems, artificial neural networks, genetic algorithms, fuzzy logic, and various hybrid systems, which combine two or more techniques (Kalogirou, 2003;Dincer et al, 2008). The aim of this article has been to show the possibility of the use of fuzzy logic for the calculation of performance HHO dry cell with different plate combination.…”

ABSTRACT:In this study, hydroxy (HHO) dry cell with different plate combination performances in terms of current, temperature and flow rate were experimentally investigated and modeled with RuleBased Mamdani-Type Fuzzy (RBMTF) modeling technique. Input parameters plate number and time; output parameters current, temperature and flow rate were described by RBMTF if-the rules. The dimensions of the plates were 10x10 cm 2 and 11x11 cm 2 . Current and temperature were measured for the different plate combination. This paper presents a fuzzy logic based study for estimating the uncertainty of the HHO drycell parameters. The 80 values between 90th and 270th seconds, which are not obtained from experimental work for 10x10 cm 2 and 11x11 cm 2 current, temperature and flow rate are predicted by fuzzy logic method. One of the results is; the current value predicted by RBMTF for the 11-2 plate combination and t=90 s is less than the current value from the results of the experimental work for the 11-2 plate combination and t=60 s, but higher than the current value from the results of the experimental work for 11-2 plate combination and t=120s.The comparison between experimental data and RBMTF is done by using three different statistical method. These are, root mean square error (RMSE), mean absolute error (MAE) and the coefficient of multiple determination (R 2 ). For 10x10 cm 2 dimension plate, RMSE, MAE and R 2 for the current is 0.13, 0.111 and 96.44% respectively. For 11x11 cm 2 dimension plate, RMSE, MAE and R 2 for the current is 0.07926, 0.06466 and 98.44% respectively. coefficient of multiple determinations (R 2 ). As a result, RBMTF model has shown satisfying relation with experimental results, which suggests an alternative approach to estimation of performance HHO dry cell with different plate combination.

“…If C is the fuzzy set in question and C is integrable, then the defuzzified value of C by this method is Eq. 2, where [a, b] is an interval containing the support of C. This kind of defuzzification determines z* point as the middle of area (Nguyen et al 2003;Dincer et al 2008).…”

Effects of heat treatment on physicochemical characteristics and sensory properties of different fruit juice concentrates (pekmez) were studied. Apricot pekmez had the highest viscosity followed by mulberry and date pekmez. Apricot and date pekmez had higher scores for odour, taste and consistency than others. Hydroxymethyl furfural concentration of all pekmez samples increased after heat treatments. Samples heated at 75°C showed highest L* values while at 65°C the lowest mean L* values. L* values of all pekmez samples were similar while carob Pekmez had higher L* values. Also a development of the Fuzzy Expert System (FES) was made for prediction. Using the experimental values, FES model of the system was designed. Accordance was found with experimental and FES results when compared statistically. This study provides advantage for prediction possibility of unknown sub-values', which were not experimentally studied.
