Oil analysis is one of the main methods for monitoring the status of internal combustion engines and oils to ensure the lubricant's protective performance and engine health. This paper investigate oil condition monitoring in gasoline engine using oil dielectric coefficient measurement. At first capacitive sensor pectinate type is designed and manufactured that engine oil can pass through the se...

In recent years, wireless sensor networks data is taken into consideration as an ideal source, in terms of speed, accuracy and cost, in order to study the Earth's surface. One of the most important challenges in this area, is the signaling network coverage and finding holes. In recent years, wireless sensor networks data is taken into consideration as an ideal source, in terms of speed, accurac...

Wireless sensor networks have many applications in the real world and have been developed in various environments. But the limitations of these networks, including the limitations on the energy and processing power of the sensors, have posed many challenges to researchers. One of the major challenges is the security of these networks, and in particular the issue of authentication in the wireles...

In this paper, a new algorithm for satellite attitude determination with sun sensor and magnetic sensor is designed that improves the accuracy of satellite attitude determination subsystem and robust it against sensor fault. This subsystem includes sensors and attitude determination algorithm. In order to combine sensors data, we can utilize  centralized and decentralized algorithm. Decent...

electrical sensitivity of a boron nitride nanotube (bnnt) was examined toward aniline (c6h5nh2) molecule by using density functional theory (dft) calculations at the b3lyp/6-31g (d) level, and it was found that the adsorption energy (ead) of aniline on the pristine nanotubes is a bout -19.03kcal/mol. but when nanotube has been doped with si and al atomes, the adsorption energy of aniline molecu...

electrical sensitivity of a boron nitride nanotube (bnnt)  was examined toward c2h5oh molecules by using density functional theory (dft)  calculations . it was founding that the adsorption energy(ead) of ethanol on the  pristine  nanotubes  is about -51.5 kj / mol, but when  the nanotube has been doped  with si and al atoms , the adsorption  and recovery time changed and the sensitivity of nano...
