The behavior of an aircraft can be described with a set of non-linear differential equations by assuming six degrees of freedom (3 for linear motions and 3 for angular motions) about x, y & z axis. All the aircrafts have a PID controller for autopilot control system for pitch, yaw and roll. The PID [6, 12] controllers are associated with their PID gains which can either be tuned manually or by...
In this paper, a two dimensional large signal analysis of helix traveling wave tube (TWT) is done for non-ideal beam launching. This actually means that the electrons enter the interaction region with an initial radial velocity. Focussing magnetic field is used in axial direction to confine the beam as it progresses down the interaction region. It is also shown that the TWT can sustain a radial velocity...
Results from the gas gain monitoring (GGM) system for the muon detector using RPC in the CMS experiment at the LHC is presented. The system is designed to provide fast and accurate determination of any shift in the working point of the chambers due to gas mixture changes.
The effect of multilayer, 2-D photonic band gap substrate on the performance of rectangular microstrip patch antenna at THz frequency is simulated. The radiation efficiency, gain and directivity for the proposed antennas are 93.28%, 10.46 dB and 10.76 dBi, respectively at 875 GHz. The 10 dB impedance bandwidth of the antenna is 36.67%, which is ultra-wide bandwidth. The simulation has been performed...
