a novel ultra wideband microstrip bandpass filter using radial stub loaded resonator and interdigital coupled lines is presented in this paper. the radial stub loaded resonator and decagonal patch form a resonator named m to create tuneable multiple notches in the passband for suppression wlan interference. to realize sharp roll-off, two adjustable transmission nulls are located at the lower an...
The roll dynamics of a 5kg, 1.3 m high sounding rocket are analyzed in a vertical wind tunnel. Significant turbulence in the tunnel makes the system identification of the effective inertia, damping and asymmetry with respect to roll challenging. A novel method is developed which decouples the disturbance from the rocket frame’s intrinsic roll dynamics and allows accurate prediction of roll rate...
– A Roll Position demand (as well as Roll Position Control) missile autopilot design methodology for a class of guided missile, based on state feedback, Ackermann pole-placement and reduced order Das & Ghosal observer (DGO), is proposed. The open loop unstable model of the roll control (or roll position demand) autopilot has been stabilized by using pole placement and state feedback. The non-mi...
Comparative misalignment disturbance functions (MDF) have been measured for rotations between display and control axes for pure pitch, roll, and yaw misalignments in a high fidelity virtual environment. Twenty participants manually moved a virtual cursor using position control to touch 3-dimensionally, randomly presented nearby targets having a constant Fitts Index of Difficulty. Results show a...
The octave illusion occurs when each ear receives a sequence of tones alternating by 1 octave but with the high and low tones in different ears. Most listeners perceive these stimuli as a high pitch in one ear alternating with a low pitch in the other ear. D. Deutsch and P. L. Roll (1976) interpreted this phenomenon as evidence for a what-where division of auditory processing caused by sequenti...
