Simultaneous conjoint measurement: A new type of fundamental measurement

The essential character of what is classically considered, e.g., by N. R. Campbell, the fundamental measurement of extensive quantities is described by an axiomatization for the comparision of effects of (or responses to) arbitrary combinations of “quantities”...

Measuring utility by a single-response sequential method.

A person deciding on a career, a wife, or a place to live bases his choice on two factors: (1) How much do I like each of the available alternatives? and (2) What are the chances for a successful outcome of each alternative? These two factors comprise...

Disintegration of Water Drops in an Electric Field

The disintegration of drops in strong electric fields is believed to play an important part in the formation of thunderstorms, at least in those parts of them where no ice crystals are present. Zeleny showed experimentally that disintegration begins as...

Optimum Locations of Switching Centers and the Absolute Centers and Medians of a Graph
