The stability of a third-order, nonlinear system with a
saturation characteristic was studied by applying the second method
of Liapunov, which is the most general approach currently used for
dynamic systems.
This thesis presents (1) the analysis of a third-order, nonlinear
system, (2) a suitable Liapunov function, generated by the...
Most studies of bacteria in water have concerned public health; little attention has been given to organisms which are indigenous to
the aquatic environment. Myxobacteria are known to occur in soil,
in the marine environment, and several have been studied in relation
to diseases of salmonid fishes. However, little information...
This analysis concerns the life and scientific work of Henry
Augustus Rowland (1848-1901), organizer and the first chairman of
the physics department at The Johns Hopkins University in 1876.
Special materials used in this research included three pieces of
Rowland's experimental apparatus which are extant in the Smithsonian
Institution Division...
Growth and reproductive patterns of the common lanternfish,
Stenobrachius leucopsarus, are described by length frequency
analysis, otolith analysis and examination of ovaries.
Length frequency analysis, employing the probability paper
method of analysis of polymodal distributions, of three and one-half
years of monthly midwater trawl collections off Oregon showed that
fish...
