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 …

Contact pressure is very critical for wear test. In order to make true wear experiment, counter body, surface, wear load, surface roughness, and the hardness of materials should be selected correctly. Maximum contact pressure forms at hertz…

In this study, mixed convection heat transfer and fluid flow in a three-dimensional horizontal duct with three different geometries of cavity were investigated numerically. Air flows in a square duct which is heated by a cavity with triangu…

In this study, combined thermal radiation and natural convection heat transfer problem are investigated in glass and plastic covered flat solar collector. The bottom plate that absorbs the sunlight and the ambient temperature are kept const…

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 r…

In the ceramic sanitaryware sector two different slips are used for different products. These slips are VC (vitreous china) and fine fire clay (FFC). Large-sized products must have low firing deformation, like washbasin, shower tray etc. ar…

Point Cloud is widely used in reverse engineering services and in many architectural works. Because the Point Clouds contain elements that reach the extreme numbers; they have increased the need to develop new methods in their management, p…

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 transfo…

The rapid increase in the world population and climate change due to industrialization require the preservation and sustainability of existing water resources. The calculation of drainage networks that are directly related to watershed mana…

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 sy…

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…

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 …

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 appr…

Today, geotourism is used as an important type of tourism in many parts of the world. Although geotourism potential of Turkey is not completely used, there are significant researches both in academic studies and in practice. In this researc…

Fotoğraf ortaya çıkışından beri insanların ilgisini çeken bir olgu olmuştur. Son yıllarda ise dijital fotoğrafçılık, fotoğrafçılık olgusuna önemli bir ivme kazandırmış ve yepyeni bir bağlama girmesini sağlamıştır. Artık fotoğraf sadece prof…

Because of the great earthquakes that have occured for centuries, many loss of lifes and goods have been experienced all over the world. Our country is located on active seismic zone. Many great earthquakes have also occurred in our country…

The concrete, which is an important building material, has a wide range of uses through its economic advantages and many other advantages. Economics, easy obtainable, long life, easy curing and workability are some of the advantages. Concre…

Today the concept of globalization is seen in every part of daily life. It effects and changes a wide span of casual life such as from sports to economy. Today all economies have been integrated to the world economy at different levels. In …

Foreign trade signifies the commencement of economic globalization and it dates back to the post industrial revolution era. Although several fluctuations were observed among different economic periods, it never lost its importance. It is se…

The fact that cannot be avoided the non-renewable energy sources (fossil and underground resources) are rapidly depleting, makes the search for new sources of energy extremely important in our country and all over the world. Besides, from p…
