Polarimeter, Rasheed M.A. Azzam

University of New Orleans Patents

To measure characteristics such as density and particle-size distributions of a medium that interacts with light, a polarimeter simultaneously develops all 16 elements of the Mueller matrix by modulating polarized monochromatic light with a quarter-wave retarder operating at a predetermined frequency before transmitting it to the medium and then modulating the light leaving the medium with another quarter-wave retarder which operates at a frequency five times that of the predetermined frequency of modulation of the light transmitted to the medium. The light is electrically detected and provides a signal which may, by Fourier analysis, be broken into 25 terms. The …

Religion, technologicalization, and modernization are elements of a controversial issue which has been brought un and discussed among the religious functionaries and polity of Pakistan. The issue is, what should be the role of Islam in …

Passive Cooling And Human Comfort, Florida Solar Energy Center, Philip W. Fairey

FSEC Energy Research Center®

Comfort within buildings is primarily controlled by four major factors: air temperature, mean radiant temperature, humidity and airflow. Each can have a dominating effect. Their effects are not necessarily additive and practically never linear. There are, additionally, other factors which affect comfort including clothing, activity level and climatization. Some psychological triggers, such as certain colors, also seem to affect comfort, and "state of mind" can have major effects on individual comfort sensations. Comfort zones, therefore, are very generally defined as the zone in which 80 percent of the population will experience the sensation of thermal comfort.

Silicon As A Millimeter-Wave Monolithically Integrated Substrate - A New Look, Arye Rosen, Martin Caulton, Anna M. Gombar, Walter M. Janton, Chung P. Wu, John F. Corboy, Charles W. Magee

Henry M. Rowan College of Engineering Departmental Research

Materials suitable for use as monolithic substrates are summarized. A study of the properties of silicon substrates as transmission line media shows that serious consideration should be given to them for use at mm-wave frequencies. It is concluded that for silicon resistivities of 2000 ohm-cm or greater, microstrip loss in silicon at mm-wave frequencies is only slightly higher than that in GaAs or alumina. The cross section width of a transmission line represents an appreciable part of a wavelength when microstrip is used as an impedance transformer at mm-wave frequencies. Therefore, substrate thickness (using the latest dispersion characteristics) is especially …

Electrical and Computer Engineering Faculty Research & Creative Works

We report very intense photoluminescence in spray-pyrolyzed CdTe at 77 K. We also notice striking similarities in the luminescence spectra, decay, and temperature dependence between CdTe and other thin-film semiconductors, which we interpret in terms of recombination at defect sites in intergranular regions.

Highway Finance — 1981 Update, Jean E. Hittle

Indiana Local Technical Assistance Program (LTAP) Publications

This Bulletin --- "HIGHWAY FINANCE - Update 1981" --- has been compiled to provide Local Road and Street Officials with a year-end report on the results of the 1981 gas tax legislation, as well as an updated estimate of anticipated revenue for Calendar Year 1982.

Total highway-user revenue for 1981 was up some $39 million over 1980 totals; this is about 6% over the totals forecast back in July. And on the basis of the 1981 experience, the 1982 total revenue estimate is up to $393 million -- a $23 million increase over the July forecast. If the 1982 experience …

Contours Of Constant Principal Angle And Constant Principal Azimuth In The Complex Ε Plane, R. M.A. Azzam

Electrical Engineering Faculty Publications

For light reflection at a planar interface between two homogeneous isotropic media with complex relative dielectric function ε, we show that the constant-principal-angle contours are a family of semicircles, whereas the constantprincipal-azimuth contours are a family of (segments of) hyperbolas in the complex ε plane. We also find the exact envelope curve of both families and hence determine the domain of the ε plane of multiple (three) principal angles that is bougded by the envelope curve and the real axis. A unique and peculiar interface with ε = (5 - j√2)/27 is shown to have three coincident principal angles of …

Energy In Agriculture: Energy Resource Series For Youth And Adult Energy Programs: 3. Oil And Gas, George M. Turner

Agricultural Engineering Energy Series

The oil and gas in the earth today were formed many millions of years ago, long before humans appeared on the scene. Therefore, man can only theorize about the origin of these fossil fuels.

The most widely accepted theory is that the oil and gas found in the earth today had their beginnings in decomposed animals and plants. The decomposition was caused by bacteria and chemicals called enzymes which digested the plant and animal bodies.

Energy In Agriculture: Energy Resource Series For Youth And Adult Energy Programs: 5. Solar, George M. Turner

Agricultural Engineering Energy Series

Since 1973, when the public became aware that shortages of gasoline for automobiles could drastically affect their personal lives, there has been much interest in solar energy. Many articles have appeared in the popular press about the potential of solar energy, and the federal government has allocated large sums of money for research in this area of energy. Most science textbooks now contain a chapter or two on solar energy utilization. Most engineering colleges offer courses specifically related to energy, and many of these place emphasis on the solar aspect. There is little doubt that the public, in all sectors, …

Energy In Agriculture: Energy Resource Series For Youth And Adult Energy Programs: 7. Nuclear Fission, George M. Turner

Agricultural Engineering Energy Series

Nuclear power is one of the leading sources in our search for energy. One source of nuclear power is nuclear fission, an energy-releasing process in which the nuclei of atoms are split. The energy produced is close kin to chemical energy. Similar basic laws, rules and reasoning apply.

Perhaps the best means of gaining an overall understanding of nuclear energy is to examine three of the known force fields in nature. Because of the importance of these basic concepts, this publication will concentrate on descriptions of these force fields and how they are harnessed for our use.

In addition, the …

Agricultural Engineering Energy Series

Wood is a bio-fuel. This means that it comes from living things. Lawn grass, field crops and garden plants and flowers are all in the bio-family of living things. In fact, there is no difference between the wood of today and fossil fuels of aeons ago, such as coal and oil except time. Millions of years ago all fossil fuels were lush green plants, thriving on nutrients and moisture in the earth and the photosynthesis process. These have long since died but have been preserved beneath the surface of the earth. Actually, the wood of today and the fossil fuels …

Energy In Agriculture: Energy Resource Series For Youth And Adult Energy Programs: 10. Water, George M. Turner

Agricultural Engineering Energy Series

Since early history, water has furnished man with energy. Man has always moved and settled along rivers and streams, because water makes travel easier. He soon learned to capture the movement of water in rivers, creeks and streams by inserting a wheel.

Water presents a great source of power. It has been estimated that if every available location for water power were developed, regardless of economic and environmental considerations, there would be between three and four times the power derived from all other sources. But this is impractical, because in many instances it would take more energy in materials and …

Propagation Of Traffic Noise, Kenneth R. Agent, Charles V. Zegeer

Kentucky Transportation Center Research Report

The effects of various traffic, ground cover, and geometric conditions on traffic noise propagation were evaluated in this study. There were two general methods of data collection. The first used as many as four sound-level meters and graphic-level recorders to take simultaneous recordings of the traffic stream; the second method involved a constant noise source using a random noise generator.

The L₁₀ noise level reduction per doubling of distance increased substantially when the traffic volume was less than 1,000 vehicles per hour. Wind speed and direction had a large effect on noise propagation. Ground cover also had a definite …

Development Of A Thickness Design System For Bituminous Concrete Pavements, Herbert F. Southgate, Robert C. Deen, James H. Havens

Kentucky Transportation Center Research Report

A pavement provides a functional surface for safe operation of a vehicle. The operator or passenger of a vehicle does not particularly care about the material from which the pavement structure is constructed. However, they are sensitive to such factors as speed, safety (skid resistance), and comfort (roughness). One aspect of pavement design is the selection of the thickness of the pavement and its various components sufficient to support vehicular loadings and to transfer those loadings through successive layers of the pavement - surface, base, and subgrade - to the soil on which the pavement rests. The structural design of …
