Transfer of load between precast bride slabs
(University of Missouri, 1961)
"This paper presents the procedures used and the results obtained in a series of static load tests designed to study the mechanism of load transfer between adjacent precast bridge-slab sections. These tests were undertaken as one phase of a general...
Methods of measuring electric fields
(University of Missouri--Columbia, 1966)
"To determine the potential of a spacecraft, an electric field meter is needed to measure the field at the surface and in the neighborhood of the craft. A search was made for field measuring methods which would not involve ...
Three and four coil systems for homogeneous magnetic fields
(University of Missouri--Columbia, 1964)
obtained by making zero as many terms as possible of the series for the field along the axis of the system. The parameters are presented in the form of tables and curves."--Page 1....
Determination of diffusion coefficients from viscosity measurements : effect of higher Chapman-Enskog approximations
(University of Missouri--Columbia, 1966)
"Numerical calculations based on the higher Chapman-Enskog approximations show that mutual diffusion coefficients calculated from binary mixture viscosity data agree within experimental uncertainty with the measured D12 ...
Measuring equivalent circuits
(University of Missouri, 1960)
"The equivalent circuit is a familiar tool to power system engineers. Today's large interconnected power systems often are studied as electric networks in which part of the network is a simplified equivalent of the actual system. Such equivalents...
Discussion of an Article by G. S. Ramaswamy and M. Ramaiah : characteristics equation of cylindrical shells : a simplified method of solution
(University of Missouri, 1963)
"Messrs. Ramaswamy and Ramaiah suggest an elegant procedure for determining the roots of the eighth-degree characteristic equation. The method consists of converting the eighth-degree equation into a biquadratic and then ...
The design of a single-layer microwave absorbing material
(University of Missouri, 1959)
The microwave absorbing structure considered here consists of a homogeneous lossy dielectric material backed by a good conductor. Some previous work has been done on obtaining the electric and magnetic parameters of a ...
The impedance of a coil placed on a conducting plane
(University of Missouri, 1963)
"Probe coils are useful in determining the properties of metals on which the coil is placed. An analysis and an equivalent circuit of the coil on a metal surface are needed and are presented here. The coil was assumed to ...
Dissolution rates of uranium dioxide sintered pellets in nitric acid systems
(University of Missouri, 1963)
A study of the effects of paced audio-rhythm on repetitive motion
(University of Missouri--Columbia, 1966)
The study described was propounded to determine if it is possible to provide a biophysical driving force that will stimulate the operator in repetitive tasks to work at a rhythm that is comfortable, yet more productive ...
Lightweight aggregates for structural concrete
(University of Missouri, 1955)
. 2) Formation of air voids in the concrete by omitting the fine aggregates. 3) The use of lightweight aggregates which owe their low density to the presence of enclosed voids in the aggregate. Combinations of the above methods may also be employed...
A statistical definition of perfect mixtures of solids of different sizes
(University of Missouri--Columbia, 1966)
"When mixing solids, it is desirable to be able to evaluate the performance of a mixer in terms of its ability to produce mixtures that approach the theoretical limit of uniformity. Although a satisfactory correlation ...
The mutual impedance of perpendicular half-wave antennas
(University of Missouri, 1960)
The mutual impedance of two coupled linear antennas is needed to obtain the radiation impedance of an array of linear antennas and to determine the effect of one antenna upon a neighboring antenna, for example, the effect ...
Relay protection for lines being sleet-melted by the short-circuit method
(University of Missouri, 1956)
"Sleet formation on transmission lines was recognized as a serious operating problem as early as 1916 and shortly thereafter methods were devised to melt sleet. In recent years various ways have been presented for connecting ...
Circuit waveforms for periodic waves
(University of Missouri--Columbia, 1964)
"A method using steady-state transforms is described which indicates how the sum function of a Fourier series may be obtained. The method can be applied to problems arising from circuits containing concentrated circuit parameters, but is not quite...
Loosening of bolted joints by small plastic deformations
(University of Missouri, 1961)
Formulas are derived for several cases of loosening of bolted joints caused by stresses in excess of elastic limits and accompanying permanent deformations. It is shown that loosening occurs during the initial application ...
A qualitative and quantitative measure of Aufwuchs Production
(University of Missouri--Columbia, 1966)
"Aufwuchs production was measured from its accrual on plexiglass substrates submerged in a stream. A method was developed for separating autotrophic and heterotrophic aufwuchs production and for separating this production ...
Sequence summation factors
(University of Missouri, 1955)
"This paper defines a new structural parameter called "Sequence-summation Factor" which may be used in the systematic calculation of "over-relaxation" factors for moment distribution processes. These sequence-summation ...
Investigation concerning polarization in barium titanate ceramics
(University of Missouri, 1957)
of polarized specimens, can be represented best by a Fourier series. It was found that direct voltage and even harmonic components are present in the unsymmetrical loops. The per-cent second harmonic and the electromechanical coupling coefficient both rise...
Transmission losses and economy loading by the use of admittance constants
(University of Missouri--Columbia, 1964)
factors used so-called "B-constants." These constants are not easily modified to consider changes in the transmission system or deviation from "base-case" system conditions. By starting with the equilibrium equation of a power system written in terms...
