Investigation Of The Dielectric Properties Of Grain At Microwave Frequencies, Arthur A. Kruse
Investigation Of The Dielectric Properties Of Grain At Microwave Frequencies, Arthur A. Kruse
Electronic Theses and Dissertations
The components of the complex dielectric constant of feed grains are obtained for the 8.5 to 12 gHz frequency range. The short-circuited wave guide method is employed to provide null-shift data for computer calculation of the first-order approximation of the real part of the complex dielectric constant under the simplifying assumption of negligible loss. Correction to this value is then made, where appreciable, by calculating the loss tangent from attenuation data independently obtained for the grains. The imaginary part of the complex dielectric constant then is obtained by multiplying the loss tangent by the real part. Curves of the real …
Heat Transfer By Numerical Solution For A Class Of Radiating Fins, Jia-Bo Hwang
Heat Transfer By Numerical Solution For A Class Of Radiating Fins, Jia-Bo Hwang
Electronic Theses and Dissertations
It has long been known that the heat transfer from a solid body to an ambient fluid can be increased by increasing the surface area of the solid body. Extended surfaces, or fins, are indispensable for compact heat exchangers. Geometrically, fins may be classified as straight fins, annular fins, and rod fins or spines. In most applications of fins, a fluid is circulating inside the fin-supporting pipe while the outside is exposed to another ambient fluid. The purpose of fin analysis is to find the temperature distribution in the fin and the heat transfer from the fin to the ambient …
Penny-Shaped Crack In An Elastic-Plastic Solid, Mohammad Hossein Sadeghi
Penny-Shaped Crack In An Elastic-Plastic Solid, Mohammad Hossein Sadeghi
Electronic Theses and Dissertations
The field of fracture mechanics has been of great interest to scientists for many years. In 1776, Coulomb, a French scientist, proposed a certain criterion - for yielding. This idea was later developed by an Italian researcher Tresca. More recently, Weibull, a German· scientist, studied the statistical aspect of fracture. In 1913, Inglis derived the mathematical formulae for the stress distribution around an elliptical void, and has demonstrated that for a very narrow ellipse (say crack) the stress concentration factor becomes very large. In 1921, A.A. Griffith and, a British scientist, was led by this idea to propose his theory …

Computer Evaluation Of Error-Correcting Codes For Pcm Telemetry, William W. Goddard
Electronic Theses and Dissertations
Communication in a broad sense is simply transferring information of some sort from one point to another, usually by means of electrical signals. The sender and the receiver of the information may be either man or machine. If the information to be transferred is in a numerical form, the system is called a Digital Data Communication System. This type of system is usually employed in machine-to-machine communication, but may be applied to transferring other types of information by first converting that information into a numerical (digital) form. In today's typical Digital Data Communications, the numerical data is converted to binary …

A Mathematical Model Of A River Basin, Leroy John Petrick
Electronic Theses and Dissertations
The utilization of our rivers by population and industrial activities has increased dramatically in recent years. Since the number of rivers available has remained constant, a need has been created to optimize the utilization. In order to optimize, the effects on the physical properties of the river caused by changes in utilization must be determined. Quantity, the amount of water flowing in the river, along with quality, the value of the water for further utilization, are physical properties of the river. Variations in these two properties measure the effects caused by changes in the utilization. The utilization within a basin …

A Study Of Some Physical And Chemical Properties Of Hard Red Spring And Hard Red Winter Wheat In South Dakota, Richard A. Pence
Electronic Theses and Dissertations
South Dakota is located in a transition zone between the winter wheat area to the south and the spring wheat area to the north. The summers seem to be too warm to produce the later maturing spring wheat of good test weight and of good milling quality that is in demand by consumers. Yet South Dakota remains primarily a spring wheat state because varieties and farming practices have not yet been perfected enough to overcome the problem of winter killing of winter wheat. Indications from several sources (27, 30) are that South Dakota’s wheat, especially the spring wheat, is of …

Computer Simulation Of A New Redundancy Reduction Technique, Uldis Birznieks
Electronic Theses and Dissertations
The compression of information into smaller and smaller bandwidths has been a constant struggle against an expanding demand. Since the modulation of a carrier necessarily produces sidebands, signals cannot be sent in zero bandwidth. For some time, attempts were made to beat nature, until the natural limits of noise and bandwidth were established. Men like Hartley, Nyquist, and Shannon set a sound scientific base and as a result, rules and limits have been Developed. But this struggle continues with ever more sophisticated demands. As requirements for larger amounts of scientific data arise, methods for utilizing the available means of data …
