Magnetic bearings have been applied in aerospace, new energy, bioscience, industry fields for the advantages of no-friction, no-lubrication, high speed, high accuracy, long service life and so on. The three-pole radial-axial hybrid magnetic bearing (HMB) is proposed to reduce the axial length of the magnetic bearings [1]. As the axial length of shaft is reduced, the critical speed can be increased...
The recent upsurge of research toward compressive sampling and parsimonious signal representations hinges on signals being sparse, either naturally, or, after projecting them on a proper basis. The present paper introduces a neat link between sparsity and a fundamental aspect of statistical inference, namely that of robustness against outliers, even when the signals involved are not sparse. It is...
The ability of Vertical and/or Short Take-Off and Landing is the objective of advanced fighter and shipboard fighter. In this paper we proposed a prototype of tailless configured STOVL aerial vehicle. Based on which, the mathematical model was studied by mechanical analysis and CFD (Computing Fluid Dynamics) computation. Besides, an intelligent adaptive based control law was proposed and the optimization...
An important task for target localization is camera calibration, whose purpose is to estimate the internal and external parameters of cameras. A exact mathematical model was established based on a strict geometric constraint relationship. A fast method of external common tangent was provided to obtain the image coordinates. The other parameters of the camera was computed in a reasonable method to...
The rule "insulation resistance halving for a 10 degC increase in temperature for rotating machine insulation" has been widely used in the industry. The rule was established based on testing of some insulation systems during the late 1950s. IEEE standard 43-2000 also provides a chart of the insulation resistance temperature coefficient versus temperature for correction of insulation resistance...
