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...

"A method is described for obtaining the trees of a v vertex complete graph through an iterative process. The iterative process is as follows, first find all the trees of a 3 vertex complete graph, then by an appropriate ...

"Digested sludge lagoons were originally considered temporary sludge storage devices; however, it was found that with prolonged storage a lagoon became an effective drying unit. Since they provide one of the more economical ...

"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...

"Electric field meters are used for the measurement of the electric field at the surface of the earth, on airplanes and on satellites. For research work and calibration of the meters, a uniform electric field facility is ...

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 ...

"A set of subroutines is discussed, which is designed to aid in the programming of computations on indexed lists of numbers using machine language or a symbolic assembly system. The most commonly performed list operations ...

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....

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 ...

"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 ...

"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...

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 ...

"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 ...
