Application of of ray tracing technique into S-UTD-CH model [Işin Izleme Tekni?inin EKDZ Modelinde Kullanilmasi]
(Institute of Electrical and Electronics Engineers Inc., 2015)
To make higher accuracy predictions having less computation complexity, lower computation time, a lot of electromagnetic wave propagation models are developed. These models are classified into two classes, ray tracing based ...
Investigation of an alternative fuel for diesel engines
(Polish Academy of Sciences, 2015)
Internal combustion engines use generally fossil fuel products. World resources of it is limited. Renewable alternative energy sources are getting important solution for energy demand. Hazelnut oil ethyl ester is obtained ...
Soil stabilization with using waste materials against freezing thawing effect
(Polish Academy of Sciences, 2015)
Freezing-thawing processes hapenning in seasonally cold climate cause deformation of soil in time of freezing and strength loss while thawing. Problems of ground frost heave and soil softening belong to the important ...
Evaluation of electromagnetic interference emitted from compact fluorescent lamps according to CISPR-15
(Electromagnetics Academy, 2015)
In this study, Electromagnetic interference (EMI) emitted by the compact fluorescent lamps (CFL) having biggest pie in the market has been investigated according to CISPR-15. Emissions of CFLs vary depending on trademark, ...
ZnO thin film synthesis by reactive radio frequency magnetron sputtering
(Elsevier B.V., 2014)
In this study, ZnO thin films were deposited on glass substrates by reactive RF magnetron sputtering method at argon-oxygen gas mixing (1:1) atmosphere. Some properties of the synthesized films were investigated by ...
A causal and effect model for knowledge flow analysis among firms
(Computers and Industrial Engineering, 2014)
Examination of the relations among firms with respect to knowledge flows is essential for sustainable development and creative economy in global competition as well as for governments, investors and decision makers. Knowing ...
