Bu çalışmada, Ultra Yüksek Moleküler Ağırlıklı (UYMA) PE-1000 plastik malzemenin abrasiv aşınma performansı incelenmiştir. UYMA, yoğunluğu 0.930–0.935 g/cm3 arasında değişen ve molekül ağırlığı 2-6 milyon seviyesinde olan bir polietilen grubudur. Yüksek molekü…

Faz değişimli malzemeler, kristal yapıları sıcaklığa bağlı olarak değişen, kristal ve amorf fazlarında elektriksel ve optik özelliklerinde büyük farklılıklar gösteren malzemelerdir. Günümüzde, başta Flash ve DRAM hafıza teknolojilerine alternatif olarak görüle…

ZnO nanopowders were synthesized via microwave assisted hydrothermal method at different precursor solution molarities. For this, the aqueous solutions of zinc aceatate dihydrate and sodium hydroxide were prepared at different molarity as precursor materials…

Palladium-catalyzed Suzuki Miyaura cross coupling reactions (SM Coupling) are made using organoboronic acid and halides. 9-(4-anthracene-9-yl-phenyl)-9H-carbazole (III) was synthesized by using Ullman and Suzuki coupling reactions. Structural analysis of the…

Here we discussed the electrical performance of Photovoltaic (PV) panels of natural dust accumulation by wind, bird droppings etc., over time which is of great importance especially for the areas where the rain density are high [1, 2]. In this study, the eff…

In recent times, anthracene-based organic thin film transistors, organic light emitting devices (OLEDs), solar cells and dye sensitized solar cells can be used to due to such features achieve high efficiency effective charge excellent and carrier mobility. Ele…

Lubricant oils are products designed to form a protective film that reduces wear and friction of machinery moving parts, protect against corrosion, cool surfaces, and reduce energy consumption. During operation, lubricant undergoes chemical changes due to cont…

The major part of freight transportation in Turkey is conducted by highway, the increase in the number of trucks and other heavy vehicles, as well as legislations allowing an increase in axle load that lead to deterioration such as rutting in flexible road pav…

Bitumen polymer modification has a long history. However, most of the polymers currently used as additive in bitumen are not economically attractive. Thus, employing recycled materials in flexible highway instead of virgin ones has become a fundamental case …

Various deteriorations primarily rutting occurs in hot mix asphalt under conditions of traffic, climate and environmental in length of time. To increase the resistance of mixtures and thus delaying these deteriorations, the various additives are added to the b…

Touristic behavior is a modern behavior that develops against modern urban life. At the core of this behavior exists search and demand for diversity which is developed to the narrative for the people who are left behind. The increasingly bureaucratic and indus…

Maxwell denkleminin AV formülasyonu esas alınarak, zamana bağlı bir akım altında süperiletken telin elektromanyetik özelliklerini çözmek için yeni bir sayısal model geliştirilmiştir. Farklı akım genlikleri için alternatif akım (AA) kayıpları hesaplanmış ve iki…

For a successful thermal performance, the right choice and design of the thermal management materials used in LED die-moulding, cooler and soldered parts is a critical engineering problem. Because they are affected by heat emitted from the pn junction in the L…

Bu çalışmada, 596 kayıt ve 31 sütundan oluşan veri setiyle R programlama dili üzerinde akciğer kanserinin ikili sınıflama başarısı test edilmiştir. İlk aşama veri setinin temizlemesi, boş değerlerin kaldırılması ve verilerin denetlenmesinden oluşmaktadır. Daha…

Global Software Development (GSD) brings together teams from diverse regions and cultural backgrounds, allowing for the pooling of varied expertise and perspectives. However, this international collaboration often comes with significant challenges, such as com…

Quality control in the industry is becoming increasingly important as a result of increasing market competition and the need for quality products. The increasing complexity of industrial processes and the increase in the amount of data available have promoted …

Yapay sinir ağları makine öğrenmesi alanında birçok problemin çözümünde sıklıkla kullanılmaktaydı. Fakat “Yapay Zeka Kışı” olarak da adlandırılan dönemde ilk olarak donanımsal kısıtlamalar ve diğer problemler sebebiyle bu alandaki çalışmalar durma noktasına ge…

Three-phase asynchronous motors are widely used in many areas of industry. Unplanned malfunctions in the motor can cause the entire system to become inefficient. Detecting and intervening the malfunctions before they grow has a direct impact on the life of the…

Detecting objects meaningfully and correctly have been challenged problem for years. Several algorithms and techniques have been developed for the extraction of man-made objects from high resolution remote sensing imagery. This paper describes and comparison t…

Digital image processing has become popular research area recently because of its widespread application compatibility such as security, robotics, quality control, face authentication. Skin segmentation methodology, which is a tool of digital image processing,…
