A finite difference equation is developed for the stream function in cylindrical coordinates with axial symmetry which is applicable to an irregular mesh having different length and radial dimensions. In addition, the ...

"The centrifugal governor mechanism, suitably modified, is shown to be a practical torsional vibration absorber. Equations for predicting its performance are developed, and comparisons are made with other types of ...

"The overhead projector has been used as a teaching aid for several years, in elementary education and in engineering drawing. No use of an overhead projector in kinematics has been reported, nor has there been a statistical evaluation of its...

"The elastic modulus of concrete is an important parameter in reinforced concrete design and analysis. With the increased use of lightweight aggregates for structural concrete a better understanding of the relationship ...

"Irrigation, drainage, and climatology are combined under professional corporate management of an engineer-agronomist-climatologist type to greatly increase profits on large holdings of flat humid lands. A pioneering development in the Mississippi...

"In the current literature, two different approaches to sampled-data theory prevail. One approach emphasizes the z-transformation methods for design and synthesis. The other approach emphasizes the Laplace transformation ...

In the designing of phase-shift oscillators it is advantageous to make the loss in the phase shift circuit a minimum, so that an amplifier of minimum gain may be used. A method of obtaining such a design has been developed ...

"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...

"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 ...

The Electronic Position Indicator is a radar-like device for the study of hand motions. First, a rederivation of the theory is presented to show its application to this situation. Then, the accuracy of the positional ...

"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...

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....

"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 ...
