Zonation Of Central U. S. Earthquake Sources, G. L. Hempen, M. J. Klosterman, B. H. Moore, John D. Rockaway, Gerald B. Rupert

International Conferences on Recent Advances in Geotechnical Earthquake Engineering and Soil Dynamics

A variety of analyses are utilized in developing potential earthquake ground shaking at a specific location. Geological procedures for estimating causes of earthquakes are fundamental to the prediction of ground motions. Evaluations of geologic factors compliment mathematical assessments of seismological data. Earthquake potential in the Central United States is predicted using the concept of seismic source zones due to the difficulty of determining active faults. Resolution of these geographic source zones is dependent upon knowledge of historic seismicity, pertinent geologic features, and causative tectonics. Regardless of the method used to delineate source zones, these zones must be geologically and seismologically …

Angular Differential And Total Cross Sections For The Excitation Of Atomic Hydrogen To Its N=2 State By Helium Ions, John E. Aldag, Jerry Peacher, Paul J. Martin, V. C. Sutcliffe, Jacob M. George, E. Redd, Thomas J. Kvale, D. M. Blankenship, John T. Park

Physics Faculty Research & Creative Works

Differential cross sections for 15-100 keV He⁺ excitation of atomic hydrogen to its n=2 level have been determined for c.m. angles from 0 to 8 mrad. The differential cross sections are obtained from an analysis of the angular distribution of the scattered ions which have lost an energy corresponding to the excitation of the target to its n=2 level. The shape of the differential cross section changes rapidly with increasing incident energy. At 15 keV, the differential cross section falls off by a factor of 5 in 6 mrad. At 100 keV, the differential cross section decreases by nearly …

Feature Frequency In Concept Learning: What Is Counted?, Ronald Thomas Kellogg

Psychological Science Faculty Research & Creative Works

Frequency theories of concept learning assume that people count how often features occur among instances of a concept, but different versions make various assumptions about what features they count. According to the basic feature model, only basic features are counted, whereas according to the configural model, basic features and configural features (all combinations of basic features) are counted. Two experiments assessed the predictions of both versions of frequency theory. Subjects viewed schematic human faces, which included both positive and negative instances of the concept to be learned, and then provided typicality ratings, classification responses, and frequency estimates of configural features, …

Effect Of Polarization And Absorption On Differential Cross Sections And Angular Correlation Parameters For Electron Excitation Of Helium, M. E. Stewart, Don H. Madison

Physics Faculty Research & Creative Works

The effects of local polarization and absorption potentials on differential cross sections and angular correlation parameters are studied within the distorted-wave approximation for electron excitation of the 2 ¹P state of helium. For examining the effect of local polarization, we have compared a recent numerical self-consistent adiabatic polarization potential for helium with the commonly used hydrogenic adiabatic polarization potential. Different radial regions for the polarization potential were studied to determine their contribution to the overall effect of polarization. Calculations are also presented which show the effects of different strengths for a local absorption potential.

Behavior Of C- And Z-Purlins Under Wind Uplift, Parviz Soroushian, Teoman Peköz

CCFSS Library (1939 - present)

INTRODUCTION Cold-formed steel lipped channel (C-) and Z-purlins are used widely in the roofs of metal buildings. They are easy and economical to fabricate and erect. However these sections are weak in the lateral direction and in torsion. In order to use their full bending capacity in the strong direction, they must be braced in the lateral direction and against twisting. Roof panels which are connected to the purlins do provide to some extent such bracing effect by virtue of their shear rigidity and resistance to local bending at the connections. Wind uplift is an important design condition for roof …

A Suggested Course In Introductory Computer Programming, Warren A. Harrison, Kenneth I. Magel

Computer Science Faculty Research & Creative Works

Introductory programming courses have long been a popular topic of discussion. Often it is either the only computer course a student takes, or it is the foundation upon which all further training in computer science is built. The usual goal of such a course is to introduce the student to the use of a computer to solve simple problems in his or her particular discipline. Generally, the method of presenting the material may be separated into two distinct schools of thought, which we have termed the "Black Box School of Thought" and the "White Box School of Thought". In this …

Structure And Properties Of Neodymium Chromite, David Charles Hitchcock

Masters Theses

"Pure, accepton and Al doped NdCrO₃ were prepared by an organo-metallic process.

The crystal structure and lattice parameters were determined by x-ray diffraction. All compositions were orthorhombic Pbnm.

Pellets were pressed from powders of each composition and sintered to high density in a reducing atmosphere. When a small amount of Fe was substituted for Cr, the powder could be sintered in air.

Electrical conductivity for acceptor doped NdCrO₃ varied from about 1 (ohm cm)^-1 at room temperature to about 10 (ohm cm)^-1 at 900°C, about two orders of magnitude higher than the electrical conductivity of the …

Kinetic Processes In A High Pressure Laser Generated Plasma, Danny Joe Krebs

Doctoral Dissertations

"A dense sodium vapor in a high-pressure noble buffer has been simultaneously excited by short (4 ns) laser pulses from two lasers: ii the first tuned to one of the 'D' line transitions and the second tuned to either the photoionization threshold of the 3p states near 406 nm or to a higher level 3p-nd resonance. The population densities of the excited levels of atomic sodium were measured with temporal resolution by absolute intensity measurements of excited state fluorescence. At early times (~100 ns), excited state populations are determined by energy transfer collisions between two laser-excited 3p atoms while the …

A Determination Of The Energy Storage Capacity Of The Diels-Alder Reaction Between Methylfuran And Maleic Anhydride As Applied To Storing Solar Energy, Brent Gregory Sparks

Masters Theses

“The heat storage capacity of the Diels-Alder reaction between 2-methylfuran and maleic anhydride is calculated using reaction parameters obtained from solution calorimetry. An equilibrium constant of .614 1/mol and a heat of reaction of 14.33 Kcal/mole were obtained from experiments at 45°C. A reaction ΔC_p of -21.8 cal/mole was calculated from heat capacity information at 25°C. From these parameters, a solution initially seven molar in methylfuran and maleic anhydride was found to have a maximum apparent volumetric heat capacity of about 1.85 times that of water. This maximum occurs at about 335 K. Typical active solar energy schemes operate …

High Voltage Powerline Injury Studies, A. Sances, S. J. Larson, J. F. Szablya, J. Derald Morgan, J. B. Myklebust

Electrical and Computer Engineering Faculty Research & Creative Works

Current pathways and reconstructions of human injury after contact with distribution powerlines are not well understood. The impedance, currents, and modes of tissue destruction are rarely known. Eight anesthetized hogs, weighing 68 to 90 kg, were used in studies with potentials ranging from 2,100 to 14,400 volts. Electrical contact was made between the hindlimbs, from the hindlimb to forelimb, and over other regions of the body. Currents from 4 to 70 amperes rms and impedances ranging from 130 to 477 ohms were measured. Phase angles up to 40° were observed. Copyright © 1981 by The Institute of Electrical and Electronics …

Fast Transient Contingency Evaluation In Power Systems, Rodrigo S. Chamorro, Max Darwin Anderson, Earl F. Richards

Electrical and Computer Engineering Faculty Research & Creative Works

The problem of creating a practical computational tool to perform transient contingency analysis in a power system control center is considered. The computer program developed may be used in a control center computer where a state estimation program or a consistent set of load flow data is available. It can be run on a periodic basis over a previously specified contingency list, or it can be called by the system operator to analyze a particular contingency. The transient behavior of the system is evaluated based on a simulation technique widely acknowledged for its fast solutions. The method uses rapidly convergent …

"It is difficult to imagine a world without plastics. Although the development of most modern plastic materials took place after 1930, such mat􀃞ria1s are so common today that the word "plastic" is often used as an adjective to connote cheapness or lack of substance. Nevertheless, it 1s important to remember that for many uses plastics offer technical and cost advantages over other materials.

Glow Discharge Polymerization., H. Yasuda

Chemistry Faculty Research & Creative Works

In this review-paper the author summarizes some important aspects of ″polymer formation″ in the glow discharge polymerization or plasma polymerization, rather than presenting a bibliographical review of work. It is shown that glow discharge polymerization can be visualized as a process consisting of three discharge processes. These are (1) controlled discharge of monomer, (2) electric discharge (glow discharge), and (3) glow discharge polymerization of the monomer. Before the electric discharge is initiated, a steady-state flow of the monomer is generally established. During this controlled discharge of the monomer (without electric discharge), adsorption of the monomer onto the solid surfaces in …

The Effect Of Plasma-Deposited Polymers On The Nucleate Boiling Behavior Of Copper Heat Transfer Surfaces, T. Hinrichs, E. Hennecke, H. Yasuda

Chemistry Faculty Research & Creative Works

The effect of plasma deposited polymers on the nucleate boiling behavior of copper heat transfer surfaces, using water as the boiling liquid, was determined. The monomers used were tetrafluoroethylene (TFE) and methane. It was found that an 18 nm thick coating of TFE enhanced the nucleate boiling, while a 150 nm thick coating reduced the nucleate boiling. Both 15 nm and 150 nm thick coatings of methane reduced the nucleate boiling, with the effect being more pronounced with the thicker coating. A surface energy effect is postulated to explain the enhanced boiling observed. © 1981.
