In the analysis of the flood routing problem, it is necessary to determine the change of the flood wave moving through the channel according to time and location, and in this context, nonlinear 3-parameter Muskingum model (NL-MUSK) is widely used. The parame…

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…

Bu çalışmada Yapay Arı Koloni optimizasyon algoritmalarının üç varyantı sürü robotların hedef bulma probleminde kullanılmıştır. Yapay arı kolonisi optimizasyon algoritmalarının Unity 3D ortamında simülasyonunu gerçekleştiren yazılım geliştirilmiştir. Sürü ro…

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…

Increasing number of motor vehicles together with economic development brings serious air pollution problems. Especially, Particle Matter emissions from Internal Combustion Engines are difficult to control and highly dangerous for human health. Both Europa and…

One of the major problems encountered designers working in the developing industry is how product can get better designs in the first stages. There are many structural optimization methods for weight reduction operations. One of them is the lattice structura…

The study presents the tribological behavior of epoxy matrix composites containing two different fillers. Hybrid composites were produced with casting method. The composites contains fillers with different particle sizes (<90µm and in the range of 150-300 µm) …

Bu çalışmada, DIN 1.2738 çeliği CVD kaplı karbür kesici takımlarla kuru kesme şartlarında tornalama deneylerine tabi tutulmuştur. Kesme parametreleri; üç farklı kesme hızı (150, 200, 250 m/dak), üç farklı ilerleme hızı (0,1, 0,15, 0,20 mm/dev) ve sabit kesme…

Diesel engines have been preferable engines for heavy, medium and light duty vehicle applications due to their superior performance and fuel economy. However, concerns with their emissions, which are highly toxic air pollutants, put some limitations to their w…

Hardox çelikler mükemmel aşınma direncine sahip, ultra yüksek mukavemetli, kayma ve darbe aşınmasına karşı dayanıklı martensitik çeliklerdir. Madencilik ve inşaat mühendisliği endüstrisinde ağır makineler ana uygulama alanıdır. Bu çalışmada, Hardox 400 çeliğ…

Complexity in the behavior of asphalt binders are further escalated with geopolymer (fly ash and the alkali liquid) modification thus, making it difficult to predict the performance of the binder accurately. This study employs artificial neural network model…

Bu çalışmada, gezici robotun verilen sahayı tam gezinmesi problemi Çinli Postacı Problemine benzetilerek çözülmeye çalışılmış, çözümün eşleşme adımına Yapay Arı Kolonisi Algoritması ile çözüm bulunmaya çalışılmıştır. Haritalanmış sahanın grafının tek derecel…

Optimal operation of the power systems is very important. In this paper, a new approach for both the economic active power flow and active power loss minimization in multi-terminal HVDC systems is proposed. In the proposed optimization approach, system constra…

This paper presents a different approach for the optimal active power flow solution in multi-terminal AC-DC systems to minimize total active power generation cost. System constraints for all of the control and state variables of both AC and DC systems are also…

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…

Because today’s architecture is characterized by various concepts and numerous designs instead of an architectural style, it is heavily described by the identity of the architect. However, according to the d-gene pool theory of Karina Moraes Zarzar, this ident…

The dimensions of discrimination in Turkey was not discussed much. Furthermore, the policy made with it is not paid attention. The ideological tools and mass media also can be responsible for this issue. The emergence of discrimination should be a matter of …

Diyarbakır buğday alanlarında 2016-2017 yıllarında buğday bitkisinin köklerinde kökbiti, Smynthurodes betae Hemiptera: Aphididae) saptanmıştır. Bitkinin köklerinde koloni oluşturarak, köklerden bitki özsuyunu emerek beslenmesi sonucu bitkinin gelişmesi geril…

Mimarlık; toplumsal, ekonomik, teknolojik boyutlarının ötesinde temelde, mekân tasarlama ve nesneleri biçimlendirme eylemi gerçekleştirir. Mimarların biçimlendirme sürecine nasıl başladığı veya hangi yöntemleri kullandığı büyük bir araştırma konusudur. Bu çalı…
