Structure And Magnetic Properties Of Rare Earth Garnets, Milan R. Kokta Jun 1972

Structure And Magnetic Properties Of Rare Earth Garnets, Milan R. Kokta

Dissertations

This study deals with preparation and magnetic properties of garnet compounds containing rare earth ions and scandium ions on two crystallographic sites: the dodecahedral and the octahedral. A number of compounds of the types {R3-yry}[rx Ga2-x](Ga3) O12' {R3}[Sc2](Fez Ga3-x) O12' {R3-y Scy}[Sc2] (Fe3) O12' and {R3-y ry)[r2 (Fez Ga3-z) O12' where R stands for large rare earth ions such as Nd3+ and Pr3+, …


Electromagnetic Wave Propagation In Nonuniform Waveguides With Perfect Conducting Walls, Irwin Share Jun 1972

Electromagnetic Wave Propagation In Nonuniform Waveguides With Perfect Conducting Walls, Irwin Share

Dissertations

The analysis of nonuniform waveguides is formulated in terms of non-orthogonal generalized coordinates by utilizing the Hertz vector potentials and the Riemann metric tensor.

When the Hertz potential is expressible as a function of the propagation coordinate times a function of the transverse coordinates, then the nonuniform waveguide may be represented by transverse equations and a set of uncoupled nonuniform transmission lines. This decomposition facilitates studying propagation along the propagation coordinate. Sufficient conditions to achieve this decomposition are investigated. It is demonstrated that these constraints may provide guidelines for selecting a useful coordinate system to describe the nonuniform waveguide. In …


An Investigation Of The Neuromuscular Command In The Control Of Respiration, Nirmal Kumar Mishra Jun 1972

An Investigation Of The Neuromuscular Command In The Control Of Respiration, Nirmal Kumar Mishra

Dissertations

The purpose of the investigation is to study the signals involved in the respiratory system and to obtain a model for the dynamics including the activity of the phrenic nerve as the input and the transpulmonary pressure, air flow and the volume as the response.

Experiments were done on anasthetized dogs under natural breathing, with steady state response to various levels of CO2 in the inspired air, and under electrophrenic stimulation. Bipolar electrodes were used at the phrenic nerve, in the cervical region, either for recording the phrenic neurogram or for supramaximal unilateral (or bilateral) stimulation using pulse frequency modulated …


Methods For Acoustic Holography And Acoustic Measurements, Wolfgang Fischer Jun 1972

Methods For Acoustic Holography And Acoustic Measurements, Wolfgang Fischer

Dissertations

In this dissertation, a novel "four-step acoustical holographic imaging system" is described and several means for its implementation are analyzed both theoretically and experimentally. This system is compared with other methods of acoustical holography, (ie. permitting to obtain a visible, 3-D image of an object insonified with supersonic waves) and some of its advantages are indicated.

The use of optical holographic techniques to convert an arbitrary acoustic image to a visible image is investigated and a new method - the "holographic sound image converter" - is introduced and analyzed. This converter consists of the "holographic interferometer" and an appropriate "coupler". …


Vibration And Buckling Of Elastic Plates With Shear And Rotatory Inertia, Bomi Batiwalla May 1972

Vibration And Buckling Of Elastic Plates With Shear And Rotatory Inertia, Bomi Batiwalla

Dissertations

The effects of shear, rotatory inertia and inplane forces on the transverse vibration of thin plates are studied. In addition, the effect of shear on the buckling of thin plates is examined. A general differential equation of motion is derived for an isotropic thin plate subjected to normal and inplane forces with the consideration of shear and rotatory inertia. The method of internal constraints and Hamilton's principle are utilized.

The resulting fourth order differential equation is solved for simply supported plates of various shapes by employing a finite difference technique. The shapes examined are a square, a circle, a circular …
