Enhancing wind direction prediction of South Africa wind energy hotspots with Bayesian mixture modeling

Rad, Najmeh Nakhaei; Bekker, Andriette, 1958-; Arashi, Mohammad (Nature Research, 2022-07-06)

Wind energy production depends not only on wind speed but also on wind direction. Thus, predicting and estimating the wind direction for sites accurately will enhance measuring the wind energy potential. The uncertain ...
Estimation of the inequality indices based on the well-known rank-based sampling schemes

Rad, Najmeh Nakhaei; Salehi, Mahdi; Mehrali, Yaser (Taylor and Francis, 2022)

Using the simple random sampling (SRS) for collecting the income data may results poor estimators specially when the sample size is not enough large. Since under this circumstance, it may be difficult to obtain a representative ...
