In situ runout identification in active magnetic bearing system by extended influence coefficient method
No full textIn this paper, an efficient, Set easy-to-use, in-situ runout identification scheme, based on the extended influence coefficient method, is presented for active magnetic bearing (AMB) systems, It is shown experimentally that the proposed scheme successfully identifies and eliminates the troublesome runout of a well-balanced AMB system in the laboratory, so that a high-precision spindle system can be achieved, while it is in operation
A NEW METHOD FOR ANALYZING TORQUE CURVES OF UNIAXIAL ANISOTROPIC MATERIALS
No full textWe present a simple analytic method to determine the intrinsic anisotropy energy K(u) and the easy axis orientation delta of a uniaxial anisotropic thin film by analyzing the torque curve. Analytical expressions for K(u) and delta are explicitly derived using the peak value in the measured torque curve and the angle where the torque is zero.We would like to thank A. K. Aganvala for helpful discussions.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
