In a system consisting of many identical machines, any set of machines may be reserved from any other machine in order that the set may carry out a production job simultaneously. A simple queuing model, entailing various approximations, is used to gi

Algebraic expressions are given for some critical jump-resonance curves in feedback systems containing one nonlinearity. The usual describing-function approximation is employed, and the following nonlinearities are considered: a) linear plus (2n + 1)

A sample of 202 former army enlisted men who served in Vietnam between 1971 and 1972 were studied 28 months after their return to a large metropolitan area. Subjects were divided into three groups, frequent ( n = 98), occasional ( n = 55) and nonuser

Vietnam veterans were divided into three groups according to their inservice narcotics use: frequent users (n = 98), occasional users (n = 55) and nonusers (n = 49). Using a blind interview procedure the three groups were found to differ in the areas

Errors in electronic function-generators using biased diodes comprise (i) ‘ electronic ’ errors due to amplifier drift, diode characteristics, etc., (ii) ‘ approximation ’ errors resulting from fitting a piecewise-linear function to a. smooth

A routine performance test on gas turbines involves the measurement of gas temperatures and pressures at a prescribed series of points in the combustion-chamber exit. A scheme is described for doing this entirely automatically, while making the conve

Transfer functions with four poles, all complex, are realized as the voltage ratio of an RC-active network, by a novel application of the ‘method of single inversion’. One operational amplifier and one inverting amplifier are needed, and the feed

Hepatitis B surface antigen (HBsAg) and antibody (anti-HBsAg) were determined on 442 asymptomatic heroin users and 246 controls. Of the drug-taking group, 124 used heroin intravenously and 318 nonintravenously (smoking, sniffing). Twenty-three (5.2%)
