The Representation(s) of Turkey’s EU Journey in Islamic Newspaper

This paper argues that relations between the EU and Turkey over the last fifty years have caused serious cracks in the Islamist media’s perspectives towards Europe. Based on the actual data, I demonstrate and discuss that while traditional political, cultural and ideological references in Islamic newspapers remain the same, the dominant discourses through which they respond to Europe and the political strategies of the Islamic-rooted, conservative Adaletve Kalkinma Partisi (Justice and Development Party, AKP) towards EU accession, show significant differences. To demonstrate this, I first offer a brief overview of the history of relations between the EU and Turkey, dealing with the major turning points of Turkey’s journey towards admission into the EU. Following this is the section focusing on shifting discourses in Turkish Islamists’ perceptions of Europe and the European Union (EU), particularly over the last two decades. This paper will then deal with actual information gathered from the four Islamic dailies (i.e., Zaman, Yeni Safak, Anadolu’da Vakit, and Milli Gazete). I utilize the techniques widely used in critical discourse analysis (CDA) in order to analyze the dominant discourses embedded in news stories which have appeared before, during, and after the release of the progress and strategy reports given by the EU in 2006

Investigation the effects of cutting parameters on power consumption in turning of haynes 242 nickel-based super alloy by RSM and GA

Talaşlı imalatta yaygın kullanımı nedeniyle tornalama işleminde güç tüketimini azaltmak sürdürülebilir bir üretim süreci için kilit faktörlerden biridir. Nikel bazlı süper alaşımlar, üstün mekanik özelliklerinden nedeniyle endüstride sıklıkla tercih edilirler. Bu çalışmanın amacı işlem parametrelerinin Haynes 242 nikel bazlı süper alaşım malzemenin tornalanmasında güç tüketimi üzerine etkilerinin incelenmesidir. Bu kapsamda, yanıt yüzeyi yöntemi (Response Surface Method-RSM) ile birleştirilen üç seviye Box-Behnken tasarımı ve genetik algoritma (GA) uygulanarak minimum güç tüketiminin tahmin edilmesinde kullanılan optimum parametre değerlerini belirlemek için regresyon modeli oluşturulmuştur. İlk olarak 3 farklı seviyedeki takım uç radüsü (0.4,0.6 ve 0.8 mm), talaş derinliği (0.2,0.4 ve 0.6 mm), ve ilerleme oranı (0.1,0.2 ve 0.3 mm/rev.) dikkate alınarak Box-Behnken deney tasarımı oluşturulmuştur. Ardından, elde edilen deney setlerine göre AdvantEdge™ vasıtasıyla her bir deney setine ait güç tüketimleri ölçülmüştür. Sonrasında, RSM’den elde edilen matematiksel tahmin modelinden yararlanılarak güç tüketimi tahmini için GA kullanılmıştır. Sonuç olarak, bu yöntemlerle bulunan tahmin değerleri karşılaştırılmış ve birbirlerine çok yakın oldukları görülmüştür. Hem istatistiksel hem de simülasyon programı sonuçları, güç tüketimini minimize etmek için düşük ilerleme oranı ve talaş derinliğine ihtiyaç duyulduğunu göstermektedir.Due to its widespread use in machining, reducing power consumption in the turning process is one of the key factors for a sustainable production process. Nickel-based superalloys are preferred in variable applications due to their superior mechanical properties. This study aims to investigate the effects of process parameters on power consumption in turning of Haynes 242 nickel-based superalloy. In this context, three levels of Box-Behnken design combined with the Response Surface Method (RSM) and genetic algorithm (GA) were applied to find the optimum parameter values used in the estimation of the minimum power consumption to create the regression model. First, the Box-Behnken experimental design was created based on 3 different levels of tool nose radius (0.4,0.6 and 0.8 mm), depth of cut (0.2,0.4 and 0.6 mm), and feed rate (0.1,0.2 and 0.3 mm/rev.). Then, the power consumption of each test measured by AdvantEdge™ based on the obtained experimental sets. Then, GA was used for power consumption estimation by utilizing the mathematical estimation model obtained from RSM. Finally, the estimated values obtained by both methods were compared. Both statistical and simulation results show that low feed rate and depth of cut are needed to minimize power consumption
