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 …

Competition projects can be defined as a process in which ideas are produced and developed to bring out high-quality places with a high potential for quality, and a multi-disciplinary environment is created for designing unique designs in which the physical, c…

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 seen that both the cla…

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 the process of econo…

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 and have caused man…

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 research, sources of geotou…

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…

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 management is very impor…

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. are produced from FFC …

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) …

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 constant. Solar collector…

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 triangular, a rectangular a…

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 point. In this stud…

ASTM G99 also known as pin-on-disk method is widely used to determine the tribological behavior of materials. But in general, there is always uncertainties in the results of wear test method. Different attempts have been made by scientists to eliminates these …

Evolution of EU road transport emission standards indicates that the limits have been reduced more than 90% in the last decades. However, nowadays, the urban populations in many developed countries are still suffering from urban transport sourced emissions. On…

Structural health monitoring allows the status of structures or components to be assessed using sensors. This method is widely used in the evaluation of the state of engineering structures, especially aviation and space engineering. Sensors used in structural …

Structural health monitoring is an interdisciplinary field that it is possible to identify defects in the structure or components of the structure at an early stage. The sensors used in structural health monitoring are called the piezoelectric wafer active sen…

The landscape sector is a form of presentation that emerged as a result of the transformation and organization of the art of gardening into a profession. Landscape has become a discipline that facilitated the development of the proviences in Turkey in terms of…

Boron is a important element that can be used in many different fields such as the ceramic industry, fertilizers, insecticides, corrosion inhibitors and etc. Boric acid is a naturally occurring compound containing boron, oxygen and hydrogen (H3BO3) elements. I…

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…
