No full textRecovery rate analysis of plasma switch and comparison with experimental results
No full textAs a most important component in power system networks, electric circuit breakers and switches protect the electric components from being damaged by fault currents. Breakdown strength and recovery rate are the two essential characteristics of an electric switch. By applying a supercritical fluid (SCF) - a potential insulating medium for high voltage switches, the recovery rate of switches can be significantly improved, owing to the combined advantages of gas and liquid. In this work a simple model for recovery rate investigation of an electric switch is proposed, aiming to roughly indicating the recovery rate of a SCF switch. The accuracy of the model is discussed through comparison with the experimental recovery rate of an air-flushed plasma switch. Both advantage and disadvantage of this model are discussed

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
