Coaxial-Type Four Terminal Computable Inductance Resistor
No full textThis Coaxial-Type Four Terminal Computable Inductance Resistor, used by Francis B. Silsbee at the National Bureau of Standards in 1915, was the most significant of the group of computable resistors used by Silsbee to establish the basis for certifying the phase angles of current transformers. At the time, potentiometer and bridge methods were coming into use in precise alternating-current measurements, which created a demand for resistances and mutual inductances of a known phase angle.35 x 58 x 6 c

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
