In this study, the elimination of zero diffraction order and twin image from three dimensional reconstructed images in digital holography and the image enhancement are desired to achieve in a short time by using hybrid methods. In addition, the brightness of t…
The effective control and treatment of chronic diseases requires access to diagnostic tests that are rapid, reliable and very sensitive. Nucleic acid based methods of pathogen detection technologies offer very rapid and accurate results with high sensitivity a…
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…
In this study, we focused on to drive a compound DC motor with a Fuel-Cell and battery, which uses hydrogen as a fuel. A fuel cell can supply maximum 40V electric. In order to drive a DC motor, it needs 200Vdc. Therefore, a microcontroller controlled boost con…
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…
Use of superplasticing chemical admixtures in concrete production is widespread all over the world and has become almost inevitable. Super-plasticizers (SPA), extend the setting time of concrete by adsorbing onto cement particles and provide concrete to preser…
Nowadays new applications and new web sites are being developed, better methods and tools are needed in order to be able to develop web or mobile applications in a fast and interactive way with minimal code structure. In this point, both the design of the appl…
This study was carried out in the pure oriental beech forests of Yenice-Kızılkay in the Western Black Sea Region of Turkey, where the changes in the number of side roots and the changes in the height and diameter of the beech trees were examined in three diffe…
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…
In this study, the effect of still water cooling on electricity generation in a thermoelectric generator heated by solar energy heat pipe is experimentally investigated. For this purpose, a heat pipe with ethyl alcohol as the working fluid has been manufacture…
In this study, AISI 430 ferritic stainless steel sheet with 0.6 mm thickness was joined by resistance spot welding at different welding times and currents. The effects of welding parameters on the mechanical properties of welded samples are defined in terms of…
Nowadays, there are old and new methods that involve the difficult problems and solution suggestions which many researchers research and try to solve. In the field of engineering, the success rates of the methods that produce solutions to these problems are of…
Stress corrosion is a dangerous type of corrosion occuring as a result of effective with corrosive environment and stress of sensitive a material. Many metallic material may be exposed to stress corrosion damage depending on operating conditions. In order to d…
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…
Building automation and control systems (BACs) allow plants in buildings to be controlled and managed, thus increasing the users' comfort and reducing the operation and maintenance costs. As far as the lighting services are concerned, control systems offer an …
The column materials in the form of monodisperse and porous particles were synthesized with regard to test their column performances in Ion Exchange Chromatography (IEC) mode. Particles in the form of poly(glycidil methacrylate-coethyleneglycol dimethacrylate)…
Nowadays, competition in industrial production has come to the top with technological improvements. In this competitive environment, producers need better quality, faster and less costly production methods. So, the use of industrial robotic systems is becoming…
Grinding of brittle material such as glass is becoming crucial in consequence of rapid growth in the area of white goods. Industrial area, during flat glass processing iron based diamond wheels can be selected in order to improve the service life of the grindi…
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…
