Type-1 recurrent intuitionistic fuzzy functions for forecasting
(Pergamon-Elsevier Science Ltd, 2020)In this study, a novel forecasting method that employs intuitionistic fuzzy c-means clustering and a grey wolf optimizer in recurrent type-1 fuzzy functions (R-T1FFs) is introduced. R-T1FFs, which adapt to the moving average ... -
Type-1 possibilistic fuzzy forecasting functions
(Elsevier, 2020)Type-1 Fuzzy Functions (T1FFs) were developed by Turksen as an alternative fuzzy inference system (FIS) and have been commonly used in forecasting problems. The main advantages of T1FFs are that they are free of rules and ... -
The determination of short circuits and grounding faults in electric power systems using time-frequency analysis
(Univ Cape Town, Energy Res Centre, 2015)In order to ensure that electrical energy reaches consumers uninterrupted, researchers constantly try to improve power transmission lines. To realize this improvement, probable faults should be analysed through every known ... -

(Mattioli 1885, 2020)Objective: This study was conducted to determine the association of the predisposition to food disgust and orthorexic tendencies to gender, BMI and some variables. It is the first study to assess food disgust, disgust ... -
Determination of Ni, Pb and Cd in drinking fountain water in Kirklareli/Turkey by FAAS after preconcentration on quercetin modified using granular activated carbon
(Desalination Publ, 2020)The purpose of this study was to determine the level after preconcentration of trace heavy metals ions using drinking fountain water (20 points) in Kirklareli province by flame atomic absorption spectrophotometer. The ... -
Activity levels of Po-210 and Pb-210 in some fish species of the Izmir Bay (Aegean Sea)
(Pergamon-Elsevier Science Ltd, 2013)Concentrations of Po-210 and Pb-210 were determined in the edible muscle tissue of twelve species of marine fish collected from Izmir Bay in the Aegean Sea Region of Turkey during the 2006-2007. Po-210 activity concentrations ... -
Seasonal variation of the concentrations of Cs-137 in sediment, sea water, and some organisms collected from Izmir Bay and Didim
(Taylor & Francis Ltd, 2014)Cs-137 in the marine environment mainly originates from fallout of atmospheric nuclear weapon tests, accidental releases from nuclear facilities, and from the Chernobyl accident. After the latter accident, many studies ... -
Common Fixed Point in C*-Algebra b-Valued Metric Space
(Amer Inst Physics, 2016)In this present paper, we establish the existence and uniqueness of the common fixed point theorem for self-maps in C*-algebra valued b-metric spaces. Besides, we give example to illustrate our theorem. Findings obtained ... -
