The absolute stability of a nonlinear control system
(1965)
The recent introduction of the Popov theorem concerning the stability of a nonlinear control has made it possible to obtain results not available from other techniques. A single loop system with an isolated nonlinearity ...
Geology of the West White Lake, South Bosco-Duson-Ridge, Abbeville-Perry-South Perry structures, South Louisiana
(1965)
The West White Lake, South Bosco-Duson-Ridge, and Abbeville-Perry-South Perry structures are located in the Oligocene and Miocene oil- and gas-producing trends of south-central Coastal Louisiana. Strata encountered by ...
Magnetic properties of lattice imperfections in alkali halide single crystals
(1965)
Measurements have been made on the magnetic properties of high purity, optical quality, single crystals of three alkali halides -- lithium fluoride, potassium chloride, and sodium chloride. A cylindrical sample was suspended ...
Diapause and developmental differences in various geographical populations of the pink bollworm, Pectinophora gossypiella, (Saunders)
(1965)
Studies in the laboratory and insectary showed at least two strains of pink bollworm, Pectinophora gossypiella (Sänders) exist north of the equator in the cotton growing areas of the Western Hemisphere, when measured in ...
A study of the properties of bismuth (III) iodide complexes in aqueous solution
(1965)
Freezing point depression, conductometric, and spectrophotometric studies have been made on bismuth triiodide in aqueous hydriodic acid solution at 25 degrees centigrade. These data indicate that the Bil₆⁻³ ion is the ...
