Dellphi programming of normality tests
(World Scientific And Engineering Acad And Soc, 2008)In this study, the source codes for the formulations of various normality tests are established on Delphi programming language. The main advantage of the programs given on this paper is that one can easily perform the ... -
Derivation of ME estimator of a mixture of two normal distributions
(World Scientific And Engineering Acad And Soc, 2008)In this study, we obtain the parameters of a mixture density by using the principle of maximum equality which is based on Shannon's entropy measure. Since this procedure doesn't require constructing the likelihood function ... -
Design of Fuzzy (u)over-tilde Control Charts
(Old City Publishing Inc, 2011)When expressing any data in linguistic terms related to a quality characteristic, traditional statistical techniques are insufficient to capture the vagueness in the data. Linguistic data can be transformed into numerical ... -

Determination of the criteria preferred in entering private pension system by Analytical Hierarchy Process
(2012)Bireysel emeklilik şirketleri sistemlerine daha çok müşteri kazandırmak için önemli çalışmalarda bulunmaktadırlar. Bu önemli çalışmalardan biri de tüketicilerin diğer şirketlere olan tercih sebeplerini ortaya çıkarmak ve ... -
Determining the problems of disabled employees: a survey study conducted in Eskisehir, Turkey
(Routledge Journals, Taylor & Francis LTD, 2011)In this study, disabled people, employed using a policy based quota method, were asked about their working lives by means of a survey. In order to do this, the population was defined as disabled people working for companies ... -
A development of entropy optimization methods
(2006)In this study by considering entropy optimization measure on the given set of moment vector functions special functional according to each measure is defined. Via the moment vector functions giving the least and the greatest ... -
Development of fuzzy ((X) over bar) over tilde - (R) over tilde and ((X) over bar) over tilde - (S) over tilde control charts using alpha-cuts
(Elsevier Science Inc, 2009)Statistical process control (SPC) is an approach that uses statistical techniques to monitor the process. Shewhart introduced the control charts that are one of the most important techniques of quality control to detect ... -
Different estimation methods for the parameters of the extended Burr XII distribution
(Taylor & Francis LTD, 2013)The extended three-parameter Burr XII (EBXII) distribution has recently attracted considerable attention for modeling data from various scientific fields since it yields a wide range of skewness and kurtosis values. However, ... -
The distribution of minimizing maximum entropy: Alternative to Weibull distribution for wind speed
(2006)In the present study, we have constructed MinMaxEnt distribution alternative to the Weibull distribution for the wind speed. MinMaxEnt distribution minimizes the special maximum entropy functional in the concrete set of ... -
Distributions of Wind Speed at Different Heights
(IEEE, 2016)In this study, the parameters of different distributions such as the Weibull, Rayleigh, Lognormal, Gamma and Generalized Gamma, which are used for modelling wind speed, at the different heights 10 and 30 m, have been ... -
The empirical performances of the selection criteria for nonparametric regression using smoothing spline
(World Scientific and Engineering Academy and Society, 2006)In this paper, the smoothing parameter selection problem has been examined in nonparametric regression using smoothing spline method for different data sets. For that reason a Monte Carlo simulation study has been performed ... -
An empirical study of fuzzy approach with artificial neural network models
(2012)Time series forecasting based on fuzzy approach by using artificial neural networks is a significant topic in many scientific areas nowadays. Artificial neural network models are sufficient due to their abilities to solve ... -
