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…

Optimal reactive power flow and economic power dispatch is very important in power systems. Optimal reactive power flow provides minimum active power loss and economic power dispatch provides minimum active power generation cost in power systems. This study pr…

Image processing methods have been widely used for detection of product faults in recent years. Images of industrial products that made of various materials are taken with different types of cameras and by using different lenses. Working on images of metallic …

It was aimed to find the structural discontinuities of the Eastern Anatolia Region by using horizontal gradient magnitude technique. When determining the structural discontinuities of the region, the maximum amplitudes of the horizontal gradient magnitude we…

Sektörel rekabetin artmasıyla, şirketler sundukları hizmet kalitesi ve ürün çeşitliliğinde birbirileri karşısında üstünlük sağlamaya çalışmaktadırlar. Şirketlerin üstünlük sağlamak için kullandığı yollardan biri de promosyon ürün veya belli bir ürün alımında…

Gelişen bilgisayar ve iletişim teknolojileri sonucunda güvenlik önemli bir konu haline gelmiştir. Güvenlik açıkları yetkilendirme, veri bütünlüğü sağlama, ağ güvenliği gibi sistemin çalışmasında etkili kısım veya kısımlarda olabilmektedir. Bir sistemin güven…

Due to the population growth, the use and management of natural resources has been one of the most important issues while ecological studies are gaining importance. In this context, the use and management of water which is the main source of life has had a maj…

In this paper, a different approach for the optimal active power flow solution in multi-terminal HVDC systems to minimize total active power generation cost is proposed. System constraints for all of the control and state variables of both AC and DC systems ar…

In this paper, three different types of coordinate transformations that are frequently used in geodetic applications are given the details of their application with evolutionary algorithms. Similarity (Helmert), Affin and Projective transformation models commo…

In addition to developing information technologies, medical decision support systems are used to make decisions more effective, faster, more accurate and easier to make decisions in medicine and healthcare. With data mining, which is an important part of med…

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…

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…

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…

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…

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…

Mobilya yüzyıllardır insanlığın kültürel zenginliğinin bir yansıması olmuştur. Aynı zamanda dünya ekonomisinde mobilya endüstrisi önemli bir yere sahiptir. Fakat bu endüstride rekabet hızlı bir şekilde artmaktadır. Mobilya ürünü için estetik, fonksiyonellik,…

Since the design of the first high rise building, the “Home Insurance Building” erected in Chicago in 1884-1885 only with 11 floors, new technologies encourage the designers to build taller and slender buildings penetrating through the sky. In the history, h…

Urban public spaces which have a place in urban design projects with different scales and degrees, are important living/living parts of the city used by everyone. These places are primarily used for mobility and access but also for official social events. In…

From the time that humans first started to live in a settled way, the effect of public places (as the common space for the people from every section of the community) on communications with their surroundings, and the need to meet the main requirements, have…
