In recent years, nanofluids, the dispersion of nanoparticles with sizes less than 100 nm in base fluids, have been attracted the interest of many researchers due to their capability of enhancing thermophysical properties. In this review paper, experimental s…
This study was conducted to assess the effects of 5 types of water: Ozonated, Chlorinated, Celestite Stone-treated, Natural Spring Waters and PinResin-treated water on performance, oxidative stress and carcass parameters in Japanese quail. A total of 150, 3-…
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 …
The present study investigates the heat transfer characteristics of swirling coaxial confined impinging turbulent air jets. Experimental range covers different values of dimensionless nozzle-to-plate distance (H / D = 0.5, 1 and 2) and dimensionless flowrate…
Pansharpening, which is transferring the spatial content of a high-resolution panchromatic (PAN) band into a lowerresolution multispectral (MS) image to produce a spatially enhanced MS image, has always been one of the hottest topics of image processing. Nume…
In this study, the effect of using a mixture of butanol and diesel fuel in a small diesel engine on engine performance and exhaust emissions is modeled. A comparison has been made with artificial neural networks, which is an up-to-date method, and multiple l…
Energy conversion systems are very diverse. One of the most important of these systems is undoubtedly the electric machines. Mechanical energy production from electricity has been ongoing for about 150 years. With rapid developing technology, it has shown a ra…
Developing technology, and electronic devices, power consumption is increasing day by day. At the present time, there are many methods used to generate electricity. Most of these methods cause environmental pollution. The share of thermal power plants in elect…
In the 20th Century the technological developments also caused the change in the building systems as in every area of life. The plate systems, the shell systems, the space-cage systems, structure systems, the pneumatic systems and the cabled systems defined as…
Current study is related with numerical simulation of a centrifugal pump impeller with the specific speed of nq=13. By the help of computational fluid dynamics (CFD) at different operating points, pump performance rsults (Head-Discharge graph) are obtained. Si…
The new material type is ‘cryogels’, which have important potential in biotechnology applications. Cryogels can be obtained from natural or synthetic polymers. It is seen that cryogens prepared from natural polymers become a preferred material group for tissue…
Since the design of the first high rise building, the “Home Insurance Building” erected in Chicago in 1884-1885 only with 11 floors, new technologies encourage the designers to build taller and slender buildings penetrating through the sky. In the history, h…
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…
