NOTE ON A SEQUENTIAL CLASSIFICATION PROBLEM
Abstract
An explicit description is given of a minimal complete class of decision rules for the problem of sequentially classifying the individuals of a group which is known to come from one of two completely specified populations.AD-265 394Div. 30U (TIPSW/RD) OTS price $7.60 Chesapeake Bay Inst., Johns Hopkins U., Annapolis, Md.

An induction conductivity temperature indicator (ICTI) is described. It consists of two selfbalancing digital direct readout indicators, one for conductivity and the other for temperature, with underwater sensing elements and 200 feet of cable. Conductivity is sensed by inducing a voltage into the sea water by transformer action and measuring the induced current with a second transformer, the sea water forming a single turn linking both transformers. The voltage output of the second transformer is then a function of the sea water conductivity and is measured by a servo balanced a.c. potentiometer. Temperature is sensed by a thermistor bead having a time constant of less than one second, and is measured by a servo balanced Wheatstone bridge. (Author)
