... Show MoreEdward Albee's career extends to more than fifty years during which he has exposed different images of male and female protagonists mostly within the same frame; domestic instability. Albee's men and women are middle-class couples who find themselves entrapped in a meaningless world. Most, if not all, of Albee's men are detached from their wives due to existential problems or middle- age crises. Women, therefore find themselves obliged to sustain their husbands and marriages alone. Women in Albee's élan are cynical, frustrated, articulate as well as brave, strong and domineering.
Marriage Play is one of Albee’s works that tackled such image of these women. The play was comm

However, the development of economic, legal and social life dictated finding agency where the principal can be dismissed and his agent to suspend agent right or the other this agency only with the consent of his right to the agency this agency is known acting non-isolated, though the basis
... Show MoreAn impressed current cathodic protection system (ICCP) requires measurements of extremely low-level quantities of its electrical characteristics. The current experimental work utilized the Adafruit INA219 sensor module for acquiring the values for voltage, current, and power of a default load, which consumes quite low power and simulates an ICCP system. The main problem is the adaptation of the INA219 sensor to the LabVIEW environment due to the absence of the library of this sensor. This work is devoted to the adaptation of the Adafruit INA219 sensor module in the LabVIEW environment through creating, developing, and successfully testing a Sub VI to be ready for employment in an ICCP system. The sensor output was monitored with an Ardui

The estimation of the parameters of Two Parameters Gamma Distribution in case of missing data has been made by using two important methods: the Maximum Likelihood Method and the Shrinkage Method. The former one consists of three methods to solve the MLE non-linear equation by which the estimators of the maximum likelihood can be obtained: Newton-Raphson, Thom and Sinha methods. Thom and Sinha methods are developed by the researcher to be suitable in case of missing data. Furthermore, the Bowman, Shenton and Lam Method, which depends on the Three Parameters Gamma Distribution to get the maximum likelihood estimators, has been developed. A comparison has been made between the methods in the experimental aspect to find the best meth

The research employs a descriptive-analytical approach to analyze current search mechanisms and test new models based on prompt engineering. The study is divided into three main sections: the general framework of the research, the theoretical framework of the role of prompt engineering, and an analysis of the applications of artificial intelligence in Islamic Jurisprudence. The findings indicate that prompt engineering significantly improves the accuracy of search results, enhances search efficiency, and reduces biases, emphasizing the importance of collaboration betw
