Sleep disorders such as insomnia, sleep bruxism, narcolepsy, and sleep-disordered breathing have different sleep quality parameters such as cyclic alternating pattern phases and A subtype phases. This study aims to analyze and predict the A phase subtypes from…

A microgrid is a power grid consists of distributed power generation units and loads. Microgrid is also a system that can operate in grid-connected mode and islanding (autonomous) mode. The control of distributed power generation units in microgrids is necessa…

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…

The next generation aircraft will be operated first with hybrid technology and then with purely electric technology, just like in the automobile industry. More electric aircraft concepts today have brought about a reorganization of the generation, transmission…

Analysis of faults in synchronous generators are so important to protect the generators and the power systems. In this paper, double line-to-ground fault analysis in unloaded synchronous generator is presented. Apart from the similar studies in the literature,…

In this study, the elimination of zero diffraction order and twin image from three dimensional reconstructed images in digital holography and the image enhancement are desired to achieve in a short time by using hybrid methods. In addition, the brightness of t…

Neural Network has been used in a number of scientific fields including medical diagnosis. It is clear that classification is one of the main challenges in any medical diagnosis. However, the drawbacks of conventional neural network classifier are summarized a…

Çalışmamız; sosyal etkileşim, tekrarlayan davranışlar, kısıtlı ilgi alanları ve iletişim sorunu olarak ortaya çıkan ve ömür boyu devam eden bir gelişim bozukluğu olan Otizmin erken tanısı üzerine gerçekleştirilmiştir. Karar ağacı algoritmaları ile Otistik Spek…

Meme kanseri kadınlarda en sık görülen kanser tipidir. Her sekiz kadının birinde meme kanserine yakalanma riski vardır. Bu çalışmada amaç meme kanserli hastaların prognostik faktörleri ile sağkalım arasındaki ilişkiyi değerlendirmektir. Demografik ve klinik …

Carbides change highly effective on the mechanical and tribological properties of the coatings. For this reason, it is very important to determine the carbide ratio in the microstructure correctly. Researchers mostly try to determine phase ratios by optical im…

A useful and flexible method based on the salp swarm algorithm (SSA) for the pattern nulling of linear antenna arrays with the prescribed nulls is presented. SSA is a relatively new population based evolutionary optimization algorithm. Nulling of the pattern i…

In the study synchronization was studied using an all-to-all network structure in a multiple system of Kuramoto oscillators. Synchronization performance was first investigated in a weakly connected system, and the effects of link strength and number of oscilla…

Anti-thyroid drugs are relatively simple molecules known as thionamides, which contain a sulfhydryl group and a thiourea moiety within a heterocyclic structure [1]. Methimazole (1-methyl-2-mercaptoimidazole) is widely used drug in medicine for treatment of hyp…

Several statistical analyses of the Pisarenko harmonic decomposition (PHD) method for frequency estimation of a single real sinusoid in noise have been carried out in the literature. However, all of the analyses consider the phase of the sinusoid as a constant…

Bu çalışmada birer adet ikili Al-9Si, üçlü Al-9Si-0,1Sr ve dörtlü Al-9Si-0,1Sr-0,6Mg alaşımı indüksiyonlu ergitme ocağında ergitme ve oda sıcaklığında tutulan kokil kalıba döküm yöntemi ile üretildi. Alaşımların yapısal ve mekanik özellikleri üretilen alaşım k…

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…

The column materials in the form of monodisperse and porous particles were synthesized with regard to test their column performances in Ion Exchange Chromatography (IEC) mode. Particles in the form of poly(glycidil methacrylate-coethyleneglycol dimethacrylate)…
