In the absence of long-term data, measure-correlate-predict methods are of great importance in the assessment of regional wind energy potential. In this study, a new MCP method is introduced for wind energy applications and tested using hourly wind data from four different regions. The method,...

This paper proposes, implements, and evaluates an original discretization method for estimating the reliability of systems for which stress and strength are defined as complex functions of continuous random variables, when reliability is not derivable through common analytic techniques. This...

In this paper, we derive the distribution of life length of a parallel system with random number of components when the life distribution of each component follows a Weibull distribution and the number of components follows a Poisson distribution truncated at zero. For two independent such...

Process capability indices (PCIs) are used to measure process potential and performance. This study constructs an uniformly minimum variance unbiased estimator (UMVUE) of the lifetime performance index based on the upper record values for Weibull lifetime model. Then the UMVUE of the lifetime...

The Weibull family is widely used to model failure data, or lifetime data, although the classical two-parameter Weibull distribution is limited to positive data and monotone failure rate. The parameters of the Weibull model are commonly obtained by maximum likelihood estimation; however, it is...

Turkey is a country that is dependent on foreign energy; the majority of Turkey's energy needs are supplied through imports. Renewable energy sources are becoming important in Turkey due to both the country's energy dependency and the disadvantages of using fossil fuels. Turkey has begun to use...
