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…
The particulate matters in ambient air were sampled in Denizli, Turkey in winter and spring using Bergerhoff Method. The average dry deposition fluxes were calculated as 152.1 ± 30.7 mg m-2 day-1 and 333.9 ± 214.2 mg m-2 day-1 in spring and winter, respectivel…
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…
Bilişsel radyo kullanılmayan ya da az kullanılan spektrum bantlarına dinamik olarak erişim olanağı sağlayan ve kullanıcılar arasında herhangi bir olumsuzluğa neden olmadan spektrum paylaşımını gerçekleştiren yazılım tabanlı bir teknolojidir. Kablosuz haberleşm…
In the world, constructions are mostly reinforced concrete framed structures with infill walls. Different reinforcement studies have been carried out on these existing structures in order to ensure the safety of life and property without heavy damage because o…
Structural health monitoring is an interdisciplinary field that enables early detection of undesirable situations such as damage or defects that occur in the structure or its components thanks to its ability to self-diagnosis. It is possible to use safer engin…
Teknoloji günümüzde her alanda kullanılmaktadır. İnsansız Hava Araçlarının da çeşitli sektörlerde (İHA) kullanımı gün geçtikçe artmaktadır. İlk zamanlarda askeri amaçlar için kullanılan İHA teknolojisi, günümüzde jeodezi, tarım, meteroloji, iletişim, acil du…

In recent years, nanofluids, the dispersion of nanoparticles with sizes less than 100 nm in base fluids, have been attracted the interest of many researchers due to their capability of enhancing thermophysical properties. In this review paper, experimental s…
The noble gas plasmas have significant importance due to their high ionization energies requiring high temperature plasma investigation of neutral atom interactions through an analytical calculation of the second virial coefficient (SVC) with preferably Mors…
Over the last few years, object recognition systems take the researchers' attention. The revolution in the artificial intelligence and computer vision systems and algorithms drives to numerous approaches. In this research, we are presenting an object recogni…
The present study investigates the heat transfer characteristics of swirling coaxial confined impinging turbulent air jets. Experimental range covers different values of dimensionless nozzle-to-plate distance (H / D = 0.5, 1 and 2) and dimensionless flowrate…
Throughout history, many studies have been done about the number of pi (), which is the anchor part of the circumference of the circle. Some of them even went forward and appointed a blessing to the pi () number or even trying to give various secrecy. Nowa…
Introduction. Environmental pollution is a global ecological problem for today. Georgia is no exception. Among the many other contaminants, the environment here poses a serious threat to military wastes left by the former soviet Army, including toxic substan…
Elektrik sistemlerinin arızasız ve güvenli bir şekilde çalışabilmesi, akım ve gerilim gibi devre büyüklüklerin 50 Hz frekansta ve sinüsoidal formda olmasına bağlıdır. Bununla birlikte bir çok nedenlerden dolayı bu temel büyüklükler sinüsoidal özelliklerini k…
Inquiry-based learning is important for students to understand scientific knowledge and the working systems of scientists to develop their knowledge. For this, students should have some skills, and if they do not have, these skills need to be gained. Some of…
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…
In this study, the effect of using a mixture of butanol and diesel fuel in a small diesel engine on engine performance and exhaust emissions is modeled. A comparison has been made with artificial neural networks, which is an up-to-date method, and multiple l…
Alfa-sipermetrinin toksik etkilerinin araştırıldığı çalışmada, gökkuşağı alabalıkları pestisitin 3 farklı konsantrasyonuna maruz bırakılmıştır. 96 saatlik akut uygulama süresinde balıklardan 0, 24, 48 ve 96 saatlerde solungaç dokusu örneklenmiştir. Solungaç …
