An Acoustic Study of an Open Flue Ogan Pipe
(1965)It is the purpose of this paper to, at the most, just break the surface in attempting to answer some of the questions which will be mentioned later in the paper and, at the least, to instill some curiosity and incentive ... -
The Performance of Plastic Scintillation Detectors
(1965)This project is concerned with the performance of plastic scintillation detectors in the detection of protons and indication of their energy. Of specific interest are proton-proton scattering events in which both ... -
Microwave Diagnostic Technique in Plasma Research: Plasma Research Program Report Number Two
(1965)This project was devised to concentrate on obtaining a measurement of the density and temperature of the plasma as a function of time. The technique to be used would be to pass electromagnetic radiation in the microwave ... -
A Proton Resonance Study of Antiferromagnetic MnCl2*4H20
(1965)In this paper we present a NMR technique for determining the orientation of the local field vectors that does not require the application of a high magnetic field. The only magnetic field required is that of a ... -
Propagation of a Plane, Small-Signal, Sinusoidal Sound Wave in a Viscous Mediuml
(1965-01)This paper presents a solution to a previously unsolved mathematical problem which arises in hydrodynamics. -
Laser Operation and Related Optical Phenomena
(1965-10-07) -
Measurement of Sound Pulse Scattering from Narrow Plates with a High-Frequency Electrostatic Microphone
(1966)The recent development of wide-band electrostatic microphones, with relatively flat response extending to one-half megacycle per second, has produced a tool with valuable research capabilities in the field of acoustics. ... -
An Estimate of the Earth's Age from Therman Considerations, Assuming Initial Conditions
(1966)Geochronology can tell us much about cosmology, but it can be no better than its data. Other methods of dating the Earth exist, but all are subject to error of one form or another. Calculation of the Earth's age from ... -
The Construction of a Transmission Line Superregenerative Receiver for Use in Pure Nuclear Quadrupole Resonance Spectroscopy
(1966)The purpose of this project was to build a device that would be both a source of r-f energy and a detector capable of detecting an absorption of energy in the 100 to 300 me range. Several types of radio-frequency ... -
An Experimental Investigation of Spectral Lines of Helium
(1966)This project involves the optics of some aspects of the concave grating spectrograph and the structure of the helium atom in attempting to account for its spectrum. Since my knowledge of the subject is severely limited, ... -
A Study of the Distribuiton of Sound Generated by an Impulsive Line Source
(1966)The shock pulse and other general spark phenomena have been studied at Kalamazoo College for a number of years under the direction of Assistant Professor Wayne M. Wright. Recent accomplishments include investigations ... -
Plotting Magnetic Fields Using Nuclear Magnetic Resonance
(1966)Since its discovery in 1945 by two independent researchers, Felix Bloch of stanford and Edward M. Purcell of Harvard, nuclear magnetic resonance has been recognized to be an extremely useful tool in research. For their ... -
Spectral andd Spatial Characteristics of Laser-Induced Spark in Air
(1966)It has been found that when an intense laser beam is focused to a point in air, electrical breakdown of the air near that point occurs, forming a spark. This paper reports on experimental investigations of some ... -
Underwater Response Characteristics of Electrostatic Transducers
(1966-01)Electrostatic transducers have been used as receivers and transmitters of ultrasonic waves at frequencies up to one megacycle per second. Transducers with solid dielectric are widely used, particularly for ultrasonics ... -
An Investigation of Wind-Induced Foam Lines on Lake Mendota
(1966-01-03)This paper is concerned chiefly with wind streaks-lines of foam and debris that align themselves parallel to the direction of the wind. It is the intent of this paper, through research done on Lake Mendota in Madison, ... -
A Study of the Shape of Low Amplitude Shock Waves in a Shock Tube
(1967)A simple form of the shock tube consists of two pieces of tubing separated by a thin air-tight diaphragm. After a pressure difference is created across the diaphragm, it is ruptured. The resulting rush of air from the ... -
Zeeman Quadrupole Studies in HgCl2 and NaClO3 Using and Induction Spectrometer
(1967)The purpose of this work was to determine a method of measuring the asymmetry parameter of the electric field gradient at the nuclear site in powdered samples. The work was restricted to nuclei having a spin of 3/2. The ... -
An Experimental Investigation 12C(p,p)12C Reaction with an Open Air Van de Graaff
(1967)The purpose of this project is to attempt an experimental verification of Ernest Rutherford's differential cross section equation with elastically scattered protons. This is obviously not the height of originality, but ...
