Floating Point Representations in Quantum Circuit Synthesis
, 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.

Wind turbine gearbox technologies [PDF]
2010 1st International Nuclear & Renewable Energy Conference (INREC), 2010 The reliability problems associated with transmission or gearbox equipped wind turbines and the existing solutions of using direct drive gearless turbines and torque-splitting, are reviewed. As alternative solutions we propose the Geared Turbofan Engine (GTF) technology, and magnetically-levitated bearings from the aerospace industry, and the ...

Effect of operating conditions on gearbox noise [PDF]
, 1992 Low contact ratio spur gears were tested in the NASA gear noise rig to study the noise radiated from the top of the gearbox. The measured sound power from the gearbox top was obtained from a near field acoustic intensity scan taken at 63 nodes just above

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT This work addresses the challenge of bidirectional trajectory tracking in solar‐powered wheeled mobile robots (WMRs), considering the mechanical structure, actuator‐driver, and power stage subsystems. Notably, this is the first study to explicitly model and control the actuator‐driver subsystem within this context. The proposed solution relies
