"Occurrence of secondary flow of a viscous fluid flowing under a pressure gradient in curved channels has often been explained by invoking the existence of boundary layers before the primary flow is established. In this ...

"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...

"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 ...

"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 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...

"The viscosity of a suspension is related to the properties of the suspending liquid and the suspended particles by measuring the viscosity of suspensions made up of closely sized materials such as glass spheres, plastic ...

"A static phase converter is a device which supplies polyphase power to a load from a single-phase power source using only passive circuit elements. Ideally such a device should produce balanced polyphase voltages at the ...

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 ...

"An experimental study of an electric arc in crossed convective and magnetic fields has been made. An electric arc was established across a rectangular test section through which argon gas was flowing at approximately ...

"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 ...

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...

"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 ...
