The α-series process is a stochastic process with a monotone trend, while the NHPP is a general process of the ordinary Poisson process and it is used as a model for a series of events that occur randomly over a variable period of time. Data on the daily fault time of machines in Bahrri Thermal Station in Sudan was analyzed during the interval from first January 2021, to July 31, 2021, to acquire the best stochastic process model used to analyze monotone trend data. The results revealed that the NHPP model could be the most suitable process model for the description of the daily fault time of machines in Bahrri Thermal Station according to lowest MSE, RMSE, Bias, MPE, and highest. The current study concluded through the NHPP the fault time of machines and repair rate occurs in an inconsistent way. The f...

Materials and Methods: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, the authors performed a systematic literature review, using three databases to assess laboratory data of COVID-19-confirmed cases, and the articles that described significant laboratory irregularities were ultimately chosen. Crosschecking was performed on the references of these articles in order to identify further studies. The statistical software R version 3.6.1 was used for meta-analysis of COVID-19 studies. Results: A total of 13 relevant articles were included. They yielded a total of 2662 individu...

(Box's M) analysis showed that the students' performance in government and private schools is not equal, both in Science and Arts section students in the basic subjects. However, (Hotelling’s Trace) test showed that there is a significant difference between the students' performance in government and private schools in both Science and Arts section student’s in the basic subjects, also the school type does affect students’ performance in the basic subject. The findings prevail that through general profile lines it is unsymmetrical about the means for students’ performance in the government and private sector and weak points for the students have been determined both in the governmental and private sector.
