This paper describes the process of designing, simulating and measuring antenna parameters in order to perform a comparative analysis performance microstrip patch antennas dipole intended for use wireless sensor networks. The implemented are designed unlicensed ISM band 2.402-2.480 GHz as one most widely used bands this type network. was created based on calculation tested simulation software, ...

the abrasion is a significant issue, especially in machining of rigid steels. a functional and suitable approach for enhancing the heat transfer from machining area is using an intermediate fluid with higher heat transfer potential instead of common fluids. the objective of this experimental study is to discuss production, stability and thermal conductivity examination of water/graphene oxide n...
