Research ArticleOpen accessIn the abstractControl of Twin Rotor MIMO System using PID and LQR ControllerSeema Chaudhary, Awadhesh KumarControl design of a TRMS system such as helicopter is very complicated task. Since the TRMS are very high non-linear system, so its non-linearity too high and the control design is very difficult problem for TRMS system. It has two rotors, the first one is the main rotor and the second one is tail rotor. The TRMS System are based … …Journal of Aircraft and Spacecraft Technology, Vol. 3, Issue 1 · 23 Oct 2019 · 7,638 accessesView PDFCite
Research ArticleOpen accessIn the abstractFree Particle Spin SpeedNicolae Petrescu, Florian Ion Tiberiu PetrescuThe electron and the proton are stable particles, compounds of the atoms, which in turn are the macroscopic scale components. A heated metal plate becomes the source of a cloud of electrons, which by an acceleration in an electromagnetic field becomes an electron beam. Protons are obtained by ionized hydrogen atoms; as the mass of the electron is negligibly small … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 5 Jul 2019 · 7,781 accessesView PDFCite

Research ArticleOpen accessIn the abstractUnderstanding Hybrid Additive Manufacturing of Functional DevicesSantosh Kumar Parupelli, Salil DesaiThe fabrication of electronic components in three-dimensional space is critical for building multifunctional devices. Traditional manufacturing approaches are limited to building planar device configurations. In order to address this limitation, our group has developed a novel hybrid additive manufacturing process that can deposit multi-material patterns on conformal substrates. This direct-write approach involves the combination of microextrusion, pico jet and laser … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 20 Mar 2017 · 8,160 accessesView PDFCite
