Detecting the Onset of Swelling in High Temperature Ceramic BiSrCaCuO Superconductors during Sintering
(1993)Superconductors are electrical conductors that have the property of carrying large amounts of current at very low temperatures (around 5-10K). These materials must undergo an intensive heating process called sintering that ... -
The Detection of Crystal Field Splitting in Eu(III) with a Narrow-band Tunable Cw Dye Laser
(1979)The development of lasers which can be tuned over a wide range, typically 50-100nm, with the output wavelength confined to a narrow-band has made it possible to increase both the sensitivity and resolution of conventional ... -
Determinant Quantum Monte Carlo simulations of charge density waves in the Holstein model with a double well potential
(2022-11-01)This work is concerned with transitions to the ordered charge density wave (CDW) phase. CDWs are well studied, but there is still more to explore, especially as they relate to superconductivity. In some instances, CDWs are ... -
Determination of Charge of Lambda Hyperfragments
(1965)The present method gives results that are at least acceptable. There are other methods that are better, chiefly: variations on presentation of data, but these are restricted in some way. The results from this method ... -
Determination of Detection Efficiencies of CsI Photodiode and Microchannel Plate Detectors
(1989)We have measured the detection efficiencies of a CsI photodiode (Si02 windowed) and a microchannel plate detector (MCP) with an opaque CsI photocathode at 1850 A. Also, a detection efficiency curve was measured for a ... -
Determination of Elastic Constants through Analysis of Ultrasonic Elastic Wave Velocities
(1982)This Senior Independent Project is a Physics Research Project carried out in the physics department at Wayne State University. This project is in the area of solid state physics, and deals. specifically with the behavior ... -
Determination of Magnetic Susceptibilities Using Nuclear Magnetic Resonance
(1967)Since its simultaneous discovery in 1945 by Felix Bloch of Stanford and Edward Purcell of Harvard, nuclear magnetic resonance (NMR) has become a research technique of great importance, especially in the areas of investigating ... -
Determination of Sound Velocities in Liquids Using Light Diffraction of Ultrasonic Waves
(1965)Previous to the writing of this paper, Paul A. McIntosh, a 1964 Kalamazoo College graduate, examined diffraction of light by ultrasonic waves. More specifically, he derived the equation for the wave1ength of sound in ... -
A Determination of the Response Characteristics of Underwater Electrostatic Transducers
(1964)High-frequency electrostatic transducers have recently found many applications as transmitters and receivers of ultrasonic waves in gases, in a frequency range extending to one megacycle. The flat response over wide ... -
The Development and Application of an Image Processing and Analyzing System
(1982)This paper summarizes the development of an image analyzing and processing system which is designed to determinegparticle size and particle size distribution of materials that have been transported atmospherically and ... -
Development of a Simple Method for Optimizing Photovoltaic Array Arrangement
(1983)Direct conversion of sunlight into electricity can be accomplished by using photovoltaic cells made of semiconductor material, which work by the photoelectric effect. Photovoltaic cells are usually connected in larger units ... -
Development of a Timing Divice Suitable for Swimming Events
(1972)This paper describes the design of an answer to the problem of inaccurate timing devices at swimming contests. The idea to build the system was conceived of during my Career Service Quarter, Sophmore year. From then until ... -
Development of Automated Equipment for Saccadic Eye Movement Experiments
(1980)This paper reports the initial design and partial construction of automated equipment for eyeball position measurement. Interface circuitry is being developed to enable a Heath Model H-11 microcomputer to control and take ... -
Development of More Efficient Fluid Catalytic Cracking Nozzles
(1996)Since the turn of the century, oil refining has been a critical industry worldwide. The continuing importance and depleting resources create the need for constant research and development in all areas of the process. One ... -
The Diffraction of Acoustic Transients in the Nearfield of a Rectangular Aperture
(1974)Working on this SIP has been somewhat of a tightrope act, balancing my efforts between the theoretical and experimental aspects of the undertaking. If either aspect of my work seems over-emphasized in this report, it is ... -
Direct Measurements of Chemical Potential Using computer simulations
(2003)When two systems of particles are in contact and allow the transfer of particles between them, they will eventually reach what is called diffusive equilibrium. Diffusive equilibrium means the two systems have the ... -
A Direct Method to Measure Tropospheric Ozone by Absorption Spectroscopy in the Ultra-Violet Region
(1974)The Air Quality Act of 1967 placed a new and greater emphasis on the research and development of air pollution detecting and monitoring systems. By 1971, enough progress in this field had been made to allow the ... -
Dynamics and Structure of Bacterial Populations under Antibiotic Stress
(2018)The development of resistance to treatment among infectious diseases is well known as a classical Darwinian phenomena. However, a mechanistic understanding of how resistance is conferred and what the implied dynamical ...
