The use of GPUs for general purpose applications is not a recent approach, but it was quickly becoming widespread with NVIDIA's CUDA (Compute Unified Device Architecture) architecture based on C programming language in 2007. Algorithms suitable for parallel op…

Gerçekleştirilen bu çalışmada, CNC dik işleme tezgâhında kesme parametrelerinin iş parçası yüzey pürüzlülüğü ve kesme kuvvetin üzerine etkileri incelenmiştir. Deneyler 1.5 mm sabit talaş derinliği, üç farklı kesme hızı (90, 120 ve 150 mm/min) ve üç farklı iler…

The effects of climate change in the world are observed to have significant effects on different environmental variables. Therefore, changes in climate parameters should be examined and analyzed. These changes can be determined by parametric and non-parametr…

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 last years, the use of alternative energy sources such as solar energy has become even more important because of environmental problems, especially the rapid depletion of fossil energy resources. There are works done for this purpose and solar energy applic…

Canlı varlıklar yaşamlarını sürdürebilmek için suya ihtiyaç duyarlar. Su yeryüzünde sürekli olarak bir dolanım halinde bulunmaktadır. Bu dolanım sırasında çeşitli sebeplerden dolayı suya karışan maddeler suyun özelliklerinin değişmesine sebep olur. Gerek suyun…

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…

Ball and beam system is an experimental set for control system design that the position of the ball on a beam is changed with respect to the reference direction by changing the angle of the beam. The PID controller is applied to this problem. The performance o…

Doğru akım motoru servo sistemlerde önemli bir tahrik unsurdur. Hız veya konum denetimi gerektiren sistemlerde kolay denetlenebildiği ve yüksek performans gösterdiği için sıkça kullanılmaktadırlar. Bu çalışmada, bir DC servo sistemin modellenmesi, durum değişk…

DIN 1.2344 sıcak iş takım çeliği; özel olarak içyapısı temizlenmiş, sünekliği ve tokluğu arttırılmış homojen mikroyapıya sahip, iyi ısıl kararlılığığa sahip olan yüksek ısıl şoklara dayanımlı bir çeliktir. Bu çelikler, ekstrüzyon kalıpları, dövme kalıpları, …

Artificial lighting is an important part of global electricity consumption. At office buildings, the energy consumed by artificial lighting can reach up to 40% of total energy consumption. This work is being done to find solutions to such problems with energy …

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…

Güç sisteminde akım ve gerilimin dalga formunun sinüsoidal formda olması gerekir. Fakat bu her zaman mümkün olmaz. Non-sinüsoidal gerilim veya elemanlar güç sisteminde harmoniklerin oluşmasına sebeb olur. Harmonikler güç sisteminde, ek ısıl kayıplara, rezona…

The aim of this study is to determine instantaneous irradiance and annual percentile sunlit time on the available rooftop floor area of Technical and Social Science Vocational School at Usak University by simulation using open source software. The building of …

Complex-valued artificial neural network (CVANN) has been developed to process data with complex numbers directly. In a CVANN the weights, threshold, inputs and outputs are all complex numbers. The convergence of the CVANN back propagation algorithm depending …

Various aromatic plants grow in different geographical regions of the world. These plants have many features such as flavor, healing, therapeutic. In addition to these characteristics, their contribution to ecological balance is very high. Since the early ages…

TiO2 films have been deposited by sol gel spin coating technique onto glass and p-Si substrates. TiO2 films were prepared using two different sols. The physical properties of the TiO2 films were examined based on two different parameters. In the first study,…

To determine the storage and consumption patterns in Samsun and its surroundings by means of source persons and to contribute to the studies conducted on this subject. In addition, it is to determine the differences related to the products according to the i…

Developing technology, and electronic devices, power consumption is increasing day by day. At the present time, there are many methods used to generate electricity. Most of these methods cause environmental pollution. The share of thermal power plants in elect…

The capitalist system’s entry of a crisis from the 70s has facilitated the "meta" of education, which first led to changes in the provision of educational services. Presentation of the education service at a price does not mean that the education is used for t…
