6. The Use of Metaphors in a Political Speech Translated From English Into Arabic
Metaphors constitute a key element of political discourse in just about any language. That being said, little has been done to investigate the use of metaphors in political-feature articles translated from English into Arabic. The authentic texts, written in both Arabic and English, involve Critical Discourse Analysis (CDA) in which texts are analyzed to examine how writers in both languages employ metaphors in the original texts. The translated texts from English into Arabic involve CDA and Contrastive Analysis (CA) wherein texts are analyzed before being compared and contrasted with the authentic texts. The results of the study show a significant level of reliance on metaphors for communicating political messages with the target audiences in the STs. This, in turn, requires an adequate translation from English into Arabic to preserve the intended messages. In other words, the present study shows the critical importance of accurately translating political metaphors from English into Arabic, which could be further justified from the perspective of conveying the most appropriate and accurate message to the target audience.
Key Words: Metaphor, Translation, Critical Discourse Analysis, Political Speech.
7. A Prioritization Approach Upon Non-Functional and Functional User Stories in Agile-Scrum Software Development (i-USPA): A Preliminary Results
Some studies claimed that negligence of non-functional user stories become the cause to failure of software products. Indeed, to achieve a high-quality software product, during the prioritization process, both functional and non-functional user stories should take into account. Although several prioritizations for user stories have been proposed so far, however, it does not provide a specific approach or technique to consider both functional and non-functional user stories during the prioritization process. Non-functional user stories are being neglected because functional user stories are considered to be more important than non-functional user stories, lack of knowledge and methodologies to accomplish non-functional user stories and the nature of Agile Software Development process itself. Therefore, this study aims to enhance the process of user stories prioritization by integrating the functional and non-functional user-stories concurrently in Agile-Scrum Software Development. This integrated technique is called as Integrated User Story Prioritization Approach (i-USPA). The studies showed the highly need of improving the user stories prioritization process would assist the Product Owner and the stakeholders to effectively prioritize the user stories process of software products. The implemented i-USPA has been evaluated through evaluation survey which addressed directly to Scrum practitioners. Its suitability and effectiveness in prioritizing user stories in Sprint Backlog will be measured based on evaluation survey feedbacks. Hence, this study concludes that i-USPA is suitable to be used for prioritizing user stories in Scrum project. It was believed the enhanced process can reduce the required time to perform the user stories prioritization task.

Developing prediction model and assessment of dominant parameters affecting laser beam cutting of stainless steel (AISI 304)
One of the most widely used thermal energy processes that can be applied to almost the entire range of materials is the laser beam machine (LBM). Any process the settings can have a significant impact on the quality of laser cutting that result. The paper addresses the application of response surface methods to mathematical model the surface roughness (Ra) and the kerf width (Kw) in Co2 laser beam cutting with the continuous wave of stainless steel SS 304. The experiment has been carried out using the Taguchi L18 mixed orthogonal network technique. A series of experiments are conducted on SS 304 stainless steel using CO2 LBM with the continuous wave to evaluate cutting process parameters such as Laser power (LP), Cutting speed (CS), Nitrogen gas pressure (GP), and Focal point position (FP). To analyze the effect of each process parameters on response regression analysis, Analysis of variance (ANOVA), and 3D surface, and contour plot was used. The experimental results were used to develop a regression mathematical model. Minitab software is used to implement the codes and to get the results. Finally, the predicted results of laser cutting conditions have been found at which the highest quality or minimum cost can be achieved. From the result obtained, response values show that Cutting speed (F – value 1.48), assistance gas pressure (F – value 0.02) has the most significant factor that affects and has little effect on surface roughness respectively. Focal point position (F – value 51.15), Laser power (F – value 0.02) has the most significant factor that affects and has little effect on kerf width respectively. The obtained results showed a good agreement between the model and the experimental data. The predictive model approach presented in this study is quite work and is expected to be useful in reducing time-consuming and expensive experimental runs.
