Abstract

 This study investigated the optimization of wear behavior of AISI 4340 steel based on the Taguchi method under various testing conditions. In this paper, a neural network and the Taguchi design method have been implemented for minimizing the wear rate in 4340 steel. A back-propagation neural network (BPNN) was developed to predict the wear rate. In the development of a predictive model, wear parameters like sliding speed, applying load and sliding distance were considered as the input model variables of the AISI 4340 steel. An analysis of variance (ANOVA) was used to determine the significant parameter affecting the wear rate. Finally, the Taguchi approach was applied to determine

The current research is summarized by studying and understanding the imagination and what resulted from it in postmodern arts, specifically Pop Art. The research was focused spatially (America) between the year 1950-1975 AD and it defined the research problem by asking about what factors and variables that established the social imagination in culture Al-Gharbia, which in turn crystallized the Western cultural product to appear in its form, which is historically called "pop art". Two studies were adopted in the second chapter. The first one was the cultural structure of the social imagination. The second topic was concerned with the stylistic diversity of pop art, and the third chapter included research and accreditation procedures. Ther

The military presence in the Gulf region after the British withdrawal from it in 1971 was one of the most important pillars of the American strategy to climb the ladder of global leadership, as the geostrategic features that the region enjoyed provided factors of controlling energy sources and global trade routes. The United States of America guarantees Western Europe and Japan the process of access to energy sources and the exclusion of its opponents from the region, especially the Soviet Union, and the growing American military presence in the Gulf after the invasion of Iraq in 2003. On the other hand, the region experiences many contradictions, some of which threaten its security, such as the exacerbation of disputes between its count

The organization is affected by and affects the attending environment. Whereas the accounting information system is one of the informational systems existing in any organization.

     The research partake capability of developing information system in economic units through design “A Integrated System of Accounting and Management Information “to enable using the relationships of an integrated from all subsystems in economic unit specially: Accounting Information System (AIS) and Management Information System (MIS).

     Also the research partake a set of basic requisites that will contribute in application An Integrated System of Accounting and Management Informat

The nature of the political system of any country in the international system must have an impact on the policy of the State, whether in the interior or exterior, both regional and international, Turkey is one of the most important countries in the Middle East, which have a place and effectiveness on the surrounding environment, hence the importance of research lies in its political system and the transfer of power in it and its transformation from the form of the parliamentary system to the presidential system of the repercussions of the task and mutual effects between Turkey and the countries of the surrounding region in terms of the extent of achieving political stability in the Turkish interior or not and how this can be refl

Regression testing being expensive, requires optimization notion. Typically, the optimization of test cases results in selecting a reduced set or subset of test cases or prioritizing the test cases to detect potential faults at an earlier phase. Many former studies revealed the heuristic-dependent mechanism to attain optimality while reducing or prioritizing test cases. Nevertheless, those studies were deprived of systematic procedures to manage tied test cases issue. Moreover, evolutionary algorithms such as the genetic process often help in depleting test cases, together with a concurrent decrease in computational runtime. However, when examining the fault detection capacity along with other parameters, is required, the method falls sh

شيد الفكر العربي المعاصر تحولات عدة فرضتها بعض التيارات الفكرية والفلسفية الغربية، وأثرت في تكوينه وتحديد اتجاهاته، فضلا عن التحديات التي بات لزاما عليه ان يتعامل معها ويمكن رد هذه التحديات الى عدة عوامل داخلية وخارجية أنتجت عدة تيارات تناولت موضوع العقلانية في الفكر العربي المعاصر، لعل أبرزها التيار الاصلاحي، التيار الليبرالي، والتيار العقلي النقدي

تُمثل عملية صنع القرار السياسي في الكويت بمراحلها وآلياتها ومؤسساتها، معياراً على مدى تقدم النظام السياسي ونجاحه في تقدم الدولة. كذلك هي معيار لمستوى قوة تجذّر الديمقراطية بين الفرد الكويتي في المجتمع، ونتاج توازن التفاعل ما بين المؤسسات السياسية مع مؤسسات الدولة الرسمية والغير رسمية، اعتماداً على القانون لا على الأهواء والمصالح القبلية والعشائرية، لتأسيس دولة مؤسسات قبل دولة أفراد.
