Exhaust gas distribution in street canyons is one of the important research subjects in urban air quality studies. Vehicle emissions are an important group of pollutants in urban areas. In this study, the dispersion of exhaust emissions from vehicles in canyon…

The structure of the gas diffusion layer influences cell performance because it also affects the passage of reaction gases and electrons. In this study, the effect of the thickness of the gas diffusion layer on the cell performance for the singlecelled PEM fue…

Eşikleme yöntemleri kenar belirleme, bölütleme ve kümeleme yaklaşımlarında sıklıkla kullanılmaktadır. Söz konusu teknikler yardımıyla renk kanallarından çeşitli sayıda kümeler elde edilebilir. Ancak, hangi yaklaşımın daha başarılı olduğu konusu belirsizliğini …

The Friction Stir Spot Welding (FSSW) method is a derivative of the Friction Stir Welding (FSW) process, which is a new welding process that recently has received considerable attention from the automotive and other industries. The studies of the different res…

In this article, the influence of the use of three different bricks on the building heat performance is compared for use on wall surfaces as a building construction element. At the beginning of the analysis, the thermal analysis of the building was carried out…

Friction stir spot welding (FSSW) method is prone to automation. In this way, by integrating the robot and automation systems have been easily developed. Thanks to the method, the effective overlapping joints can be obtained a short processing time. In the stu…

Increasing in wireless communications systems is caused to increase in the need of the frequency spectrum. CR (Cognitive Radio) measure or sense frequency spectrum activities on spectrum bands whether they are idle or used by licensed users. According to sensi…

3D printing filling structures at prototyping and design stage are increasingly important issue for products with complicated shapes. The objective of the present study is to investigate 3D printing filling structures effect on mechanical properties and surfac…

For a successful thermal performance, the right choice and design of the thermal management materials used in LED die-moulding, cooler and soldered parts is a critical engineering problem. Because they are affected by heat emitted from the pn junction in the L…

Aim of the study: It is important to be able to plan the production transmission and distribution necessary for uninterrupted electricity and to use the electricity more efficiently and to make demand forecasts. For this reason, it is aimed to estimate the ele…

In this study, research on the determination of the technological level in the greenhouse mechanization in Southeastern Anatolia Region of Turkey has been carried out. The technological equipment and operating parameters that should be in a modern greenhouse h…

In the present study, the effects of cutting parameters on surface roughness were investigated in order to determine the optimum machining conditions for the hot work tool steel (155 HB), which is an important part of the mold industry. For this purpose, the m…
