Bu çalışmada, frekans çözünürlüğünün (yankı çözünürlüğünün) R-MUSIC (Root-MUSIC, Çoklu Sinyal Sınıflandırma) ve ESPRIT (Rotasyonel Değişmezlik Tekniği ile İşaret Parametrelerinin Kestirimi) yöntemleri kullanılarak nasıl değiştiği incelenmiştir. Bu yöntemler,…
Plastic injection molding is a manufacturing process of heating plastic granules and forcing melted plastic into a mold cavity and removing from the mold after cooling. One of the most important elements in the production of parts by plastic injection molding …
Current study is related with numerical simulation of a centrifugal pump impeller with the specific speed of nq=13. By the help of computational fluid dynamics (CFD) at different operating points, pump performance rsults (Head-Discharge graph) are obtained. Si…
In this work, the effects of bis (2-methoxy-4-allylphenyl) oxalate (I) on levitation (Fz) and lateral forces (Fx) of bulk MgB2 superconductor has been investigated and reported for the first time. All samples were prepared from magnesium powder (Mg, 99.8 %),…
In the last century, there has been an ever-increasing demand for novel materials namely known as composites. Biological fibers are reinforcement materials of composite structures owing to their economic and ecological advantages. Among these fibers, plant f…
Bağcılık, Tokat ilinde bitkisel üretim bakımından önemli bir yerdedir. Fakat üzüm üretimi sırasında karşılaşılan sorunlardan biri olan yabancı otlar büyük problem oluşturmaktadır. Bu çalışma ile; Tokat ili bağlarında sorun oluşturan yabancı ot türlerinin yay…
Fuel cells can be considered as clean, efficient and economic devices for the next power generation. Flow configuration and operating conditions such as temperature, relative humidity and stoichiometric number are key factors for improving cell performance. …
Bu çalışmada, non-lineer ve dengesiz yükün bulunduğu güç sisteminde aktif filtre kullanılarak harmonik distorsiyonun değeri düşürülmüştür. Pasif harmonik filtrelerin aksine, modern aktif harmonik filtreler, güç faktörü düzeltme, gerilim regülasyonunu saglama…
Meriç River is the longest river ecosystem of the Balkans and most lotic ecosystem in Thrace Region of Turkey. Tunca River is one of the most important tributary of Meriç River. Therefore it is significantly effective on the water quality of Meriç River. In …
Over the last decade, distributed software development (DSD) becomes very popular for most of the major companies. According to the effects of globalization, software development methodologies and practices are also impressed. Because of the underlying philo…
Bu çalışmada takım elbise üretimi yapılan bir firmada klasik ceket üretimi için üretim akışı oluşturulmuş, daha sonra bu bantta zaman etüdü uygulaması yapılmış ve bu uygulama ile standart süreleri belirlenmiştir. Çalışma kapsamında, her departmana ait farklı…
Rubble of destroyed buildings in Turkey is a growing environmental problem, in Ankara only, there are 12 landfills to collect and store them. Adobe is a world common building material; many studies inferred its environmental qualities. This study examines th…
The metal ions accelerate drug action and efficiency of therapeutic compounds [1]. Metal complexes may inhibit the protein synthesis because of interference in the cellular respiration. Cancer is leading cause of fatality in recent years and remained as a ch…
Erosion is among the leading factors threatening our sources of soil and water. The use of soil susceptibility indices to determine erosion and risk situations has an important place especially in erosion studies. The susceptibility of soil to erosion is the…
In the fifth generation (5G), the traditional restrictions that limit the capacity of wireless communication must be overcome. Non-orthogonal multiple access (NOMA) is a promising solution capable of overcoming these constraints to meet the requirements of 5…
Cherry trees do not reproduce from seed. Desirable cultivars are grafted onto rootstocks which is generally clonally propagated. Many cherry rootstocks have been released around the world and a wide range of cherry rootstocks is available for growers. The cu…
Kargı kamışı (Arundo donax L.) üzerinde beslenen Melanaphis donacis’nın üç farklı sıcaklıklardaki biyolojik parametreleri (22.5 0C, 25 0C ve 27.5 0C) araştırılmıştır. M donacis’in bazı biyolojik parametrelerini incelendiğinde rm değerlerinin en düşük olduğu …
