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…

Variable magnetic fields are widely used in energy production. Two methods can be applied to make the magnetic field variable. The first of these is to apply an alternating current to the insulated conductor on the outer surface of a core. The other is to rota…

Coils are electrical-electronic circuit elements and they are obtained by winding conductive wires on top of one another on a core or space, when electrical current pass through the coils they bring a magnetic field around them. The electromotive force (emf) t…

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…

Bu çalışmada, Afyon Bölgesindeki 8” çapındaki bir doğalgaz boru hattının yüksek gerilim enerji iletim hattı ile yakın güzergahı kullanması, kesişim ve paralellik arz etmesi nedeniyle önceden hazırlanan rapora göre alınan tedbirler neticesinde boru hattının b…

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…

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…

Micro electro mechanical systems (MEMS) technology enables us to create any pattern with any dimension. There are many surface patterning techniques which help us transfer the desired pattern from mask to the wafer surface. Predefined patterns on the wafer sur…

Hyperspectral images offer a good separability among land cover classes, owing to their advantages to provide spectral bands with narrow wavelength intervals. It is also possible to further increase classification accuracy of hyperspectral images by integrat…

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…

Additive manufacturing which is developed in the last half century is promising manufacturing technology. It uses layer-wise production method for obtaining finished product. In recent years, thousand researches were made but there was still gaps about impac…

In this study, it is aimed to develop a deep learning application which detects types of garbage into trash in order to provide recyclability with vision system. Training and testing will be performed with image data consisting of several classes on differen…

In this study, it is aimed to design C pattern array microstrip antenna for C Band (4 to 8 GHz), X Band (8 to 12 GHz) and Ku Band (12 GHz to 18 GHz). The proposed geometry was fed by coaxial probe. Optimum antenna was designed with Artificial Neural Network …

In today’s developing world, capital needs, which are essential to fulfill an enterprise, still pose a problem despite the subsidies and special funds. The aim of this study is to analyze to what extent the subsidies of SMIDO in Tokat province, which is situa…

Urban illumination has great importance for reasons such as exhibiting the beauty of the city, facilitating night life, emphasizing important functional, aesthetic, historical and social spaces and works of art in terms of the city, besides the city's import…

Peyzaj mimarlığı kentsel açık alanlarda kullanıcı istek ve ihtiyaçlarını karşılayan doğa ve kültürel bileşenleri estetik ve işlevsel ölçütlere göre tasarlayan meslek disiplinidir. Tasarlanan kentsel alanlar özellikle sürdürülebilir mekanlar yaratmak ve geliş…

In this talk, we work on a model of the prey-predator system to see the effect of system components on species distribution for both temporal and spatial structure. In some cases, changing environmental conditions results in extinction or leads the survival …

In order to increase the performance/cost ratio of solar cells, new approaches reducing optical and electrical losses are necessary during the absorption of the light and collection of charge carriers. In this work we focused on various textures on Si surface …

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…

The quality control process for determining fabric faults causes high cost and time loss when performed with human eyes. Adding a real-time system to the fabric production mechanisms is very difficult to detect mistakes. In this study, 5 MP Raspberry Pi camera…
