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...
Application of the principle of corresponding states for polar substances
(University of Missouri, 1961)
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 near a conductor
(University of Missouri, 1958)
"The results are given of experiments undertaken to determine the manner in which the apparent inductance and resistance of an alternating current carrying coil changes when it is brought near a plate of non-ferrous metal. ...
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 ...
The design of sampled-data feedback systems
(University of Missouri, 1955)
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 ...
Experimental investigation of a magnetically balanced arc in a transverse argon flow
(University of Missouri--Columbia, 1966)
and velocities up to 100 m/sec. Magnetic field strengths up to 3 webers/m2, oriented so that the Lorentz force opposed the convective force on the arc, were applied perpendicular lo both the arc and the direction of the argon gas flow. The test apparatus...
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 ...
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 ...
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 ...
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 ...
Treatment of livestock waste: a laboratory study
(University of Missouri--Columbia, 1965)
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 ...
A dynamic analogy for foundation-soil systems
(University of Missouri, 1954)
"This paper presents a procedure whereby the dynamic soil constants required for the accurate prediction of the natural frequencies of a foundation-soil system may be determined. The foundation-soil system is treated by ...
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...
Head losses in storm drain junction boxes
(University of Missouri, 1957)
"The paper outlines results of model studies of a junction box designed primarily for urban highway storm drains. Only full-flowing pipes are included. Loss coefficients are derived from consideration of total head loss ...
