The testes of the gray-tailed vole (Microtus canicaudus Miller) exhibited a high affinity for selenium relative to other selected tissues. Uptake of selenium-75 in the testis-epididymis complex was delayed relative to uptake by the whole body, kidney, and liver. This pattern of uptake suggested that selenium was metabolically incorporated into...
This paper continues exploration in the area of
programming for parallel computers. The appendix to the
paper contains an extensive survey of the literature related
to parallel computers and parallel programming techniques.
The paper itself presents a new approach to solving
the Laplace equation on a. parallel computer. A new...
Interval arithmetic is applied to the problem of obtaining
rigorous solutions to integral equations on a computer. The
integral equations considered are the linear Fredholm equation of
the second kind and the nonlinear Urysohn equation. Techniques are
presented which enable the computer to find an approximate
solution, prove the existence...
We will consider the implementation of a computer program to
solve a nonlinear algebraic system of N equations and unknowns.
The program involves the use of a parameter, Newton's method, and
an automatic change of parameter. Also considered are rigorous
error bounds for the answer. The program was implemented and...
A function translator is presented which was designed for
interactive programs which allow functions to be defined on-line. The
translator handles functions which are specified by a formula and
functions which are specified as the solution to a system of differential
equations.
The approximation of a continuous function, in the maximum
norm, by continuous splines in the Everett Interpolation Form is considered.
The topics of characterization, uniqueness, and calculation
of best approximations are investigated. Since uniqueness fails, a
new vector-valued norm, which yields uniqueness, is introduced.
In this thesis some methods for solving systems of
nonlinear equations are described, which do not require
calculation of the Jacobian matrix. One of these methods
is programmed to solve a parametrized system with possible
singularities. The efficiency of this method and a modified
Newton's method are compared using experimental...
COMPLOT is a versatile set of plot drivers designed to be used
on a Tekterminal, Calcomp, or Hewlett Packard plotter in a time-sharing
environment. Although the hardware aspects of each plotting
device are quite different, COMPLOT allows the plotting devices to
be treated as if they were the same.
Merging isothermal buoyant jets in a crossflow were investigated
experimentally. Jets of salt water were discharged from a constant
head tank into the stagnant tap water. A crossflow was simulated
by towing the discharge ports through the receiving water at desired
speeds. Visualization of the jet cross-sections produced by a...
