Effect of surface species concentrations and temperature on diamond film morphology in inductively coupled r.f. plasma CVD
Autor: J. W. Lindsay, J.M. Larson, Steven L. Girshick
Publikováno v: Diamond and Related Materials. 6:481-485
Ah,;aract Diamond tilms were deposited with an r.f. plasma operating at atmospheric pressure. The gas composition above the growth surface was measured with a gas ch~-omatograph. Experiments were conducted over a range of methane flow rates and sut's

Using arc voltage to locate the anode attachment in plasma arc cutting
Autor: Joachim Heberlein, D J Osterhouse, J W Lindsay
Publikováno v: Journal of Physics D: Applied Physics. 46:224013
Plasma arc cutting is a widely used industrial process in which an electric arc in the form of a high velocity plasma jet is used to melt and blow away metal. The arc attaches inside the resulting cut slot, or kerf, where it both provides a large hea

Diamond Growth Chemistry During Atmospheric-Pressure Plasma Cvd
Autor: J. W. Lindsay, Steven L. Girshick
Publikováno v: MRS Proceedings. 416
Diamond films were deposited by chemical vapor deposition using a radio- frequency induction plasma operating at 130 torr. Linear growth rates of polycrystalline diamond films ranged from 18 to 37 μm h-1. For a fixed substrate temperature of 1000°C

An Evaluation of Substitute Methods for Derivatives in Unconstrained Optimization
Autor: David M. Himmelblau, J. W. Lindsay
Publikováno v: Operations Research. 28:668-686
Under what circumstances can finite difference approximations serve as substitutes for analytical derivatives in unconstrained optimization? Are such techniques as good as using derivative-free methods? We investigated these two questions via both th

Spontaneous occurrence of tumors in laboratory-reared arvicoline rodents
Autor: J W, Lindsay
Publikováno v: Cancer research. 36(11 Pt 1)
Data from more than 2500 laboratory-reared rodents of four arvicoline genera raised since 1966 indicated that the incidence of neoplasia increased spontaneously in a nearly linear manner from 1968 to 1974. The incidence was highest in Clethrionomys r
