Floating Point Representations in Quantum Circuit Synthesis

open access: yes, 2013
We provide a non-deterministic quantum protocol that approximates the single qubit rotations R_x(2a^2 b^2)$ using R_x(2a) and R_x(2b) and a constant number of Clifford and T operations.

Air vehicle simulator: an application for a cable array robot [PDF]

open access: yes, 2005
The development of autonomous air vehicles can be an expensive research pursuit. To alleviate some of the financial burden of this process, we have constructed a system consisting of four winches each attached to a central pod (the simulated air vehicle)

Condition Monitoring of Gearbox based on Statistical Linguistic Analysis of Time Series

open access: yesJixie chuandong, 2015
The vibration data from defective gearboxes generally exhibit non- stationary and nonlinear property. As a result,it seems hard to effectively monitor the running status of gearbox by using the conventional time domain statistical parameters method which

Space shuttle orbiter auxiliary power unit development challenges [PDF]

open access: yes, 1985
When the flying spacecraft was approved for development, a power unit for the hydraulic system had to be developed. Unlike other systems on the orbiter, there was no precedent in earlier spacecraft for a hydraulic system nor for the power unit to drive ...
