A Comparison Of The Collinear Mean And The Mean Sea Surface As Reference Levels For Altimeter Analysis In The Southern Pacific Ocean, Charles Beard

Theses

Satellites are used to study various oceanic phenomena, including sea surface temperature, color, and sea height variability (which is related to oceanic currents). In observing sea height variability from radar altimeters, three methods of analysis can be applied. They are the collinear or repeat track method, the cross-over difference method, and the mean sea surface method. All three are designed to remove the effects of geoid undulations from the altimeter records. This paper compares the collinear method with the mean sea surface method in a small geographic area. Both methods analyze the tracks of collinear altimeter data by subtracting a …

Investigation Of Steady Incompressible Flows In The Vicinity Of An Airfoil, Sivaraj Kailasapathy

Theses

O-type body-fitted coordinate systems are numerically generated about NACA0012 and NACA4412 airfoils. These coordinate systems are used to effect a coordinate transformation from the physical plane to a rectangular transformed plane. The software developed also has a coordinate contraction capability. Plots of uncontracted and contracted coordinate systems are presented.

The nonconservative, velocity-pressure formulation of the two-dimensional, steady-state Euler equations are transformed to the rectangular plane. The boundary conditions at the airfoil are determined by the source-panel method, following which, the explicit finite difference form of the transformed Euler equations are solved using a space-marching scheme. Non-lifting potential flow solutions are …

Development Of A Mathematical Model To Determine The Temperature Distribution In The Metal Layer And Hearth Of An Electrical Resistance Smelter, Kurt B. Carlson

Theses

A steady-state finite-difference heat transfer mathematical model was derived to determine the temperature distribution in the metal layer and the hearth of a cylindrical electrical-resistance smelter. The temperature distribution is required for the redesign of the refractory materials and their positions in the hearth to insure that the metal layer is kept molten at normal smelting temperatures and that mechanical and structural integrity of the hearth is maintained. An extensive literature search revealed that no previously defined model of this type existed and that consideration of a three-dimensional model was beyond the scope of this work. The literature search also …

A Multipurpose Test Mask For Exposure Tool Characterization, Brian Benamati

Theses

Of the many facets of integrated circuit fabrication, photolithography may very well be the most important due to the number of levels required for the fabrication of sophisticated devices. Therefore it is imperative to understand the performance capabilities of an exposure tool and identify its inherent limitations. Many methods have been developed which concentrate specifically on evaluating resolution, critical dimensions or registration. Often test patterns exist which vary widely for applications with respect to steppers, IX scanning projection aligners and other IX exposure equipment. The following work is focused on the requirements of evaluating and optimizing all aspects of performance …

Robotic Work Cell For Packing Canisters, Robert J. Makar

Theses

The purpose of this project is to reduce the manufacturing cost of the special order 2500cc truck canisters produced at Rochester Products' Lee Road facility. This was accomplished by designing and developing a robotic work cell to pack the canisters into baskets at the injection mold machine. A literature search was conducted to gain a broader understanding of robotic applications and end-effector design. In developing this cell, the layout of the work cell components was determined, a suitable robot was selected, and an end-effector was designed, built and tested.

Evaluation Of A Quantitative Aerial Thermography Method For The Determination Of Roof Top Heat Loss, Joseph Biegel

Theses

A quantitative aerial infrared thermographic method for the determination of residential roof top heat loss is studied utilizing data gathered on over 1000 homes in the city of Plattsburgh, New York. The aerial infrared thermographic technique used as the basis of this study accounts for atmospheric and emissivity effects on the thermogram data as well as convective and radiational losses from the roof surface. The strength of the method is tested on the basis of a multivariate first order linear regression analysis using the aerial heat flow measurements as the dependent variable and parameters derived from ground survey data as …

Image Motion Compensation For An Electronic Imaging System, James H. Cain

Theses

The design of an image compensation device is given which is capable of minimizing the in-track image disturbances caused by velocity variations in an optical scanning device. Guidelines for the development of this mechanism are based on known optical principles. Acceptable response capabilities for this device are based on subjective and quantitative image quality standards. A first order analysis of the device was conducted to specify the performance required to minimize the distortions mentioned above. The final system specifications take into account actual hardware that is currently available for the typical scanner system presented.

Jmsl - A Language Derived From Apl, John Mark Smeenk

Theses

A new AFL-derived language called JMSL is presented which rnodifies seven aspects of APL so that many current and potential APL users could benefit from a language which is easier to learn, read, write, and maintain. JMSL uses ASCII tokens instead of APL symbols to remedy interfacing, extensibility, and readability problems with APL. JMSL revises and extends APL built-in capabilities to provide greater expression and improved symbol-meaning correspondence. JMSL includes a new notation for nested arrays (a powerful data structure which combines the array processing of APL with the tree processing of LISP). JMSL provides hierarchical directories (similar to PASCAL …

Effect Of Center Of Gravity Location On Optimum Performance Of Random Vibratory Vehicle Suspension, Daniel Mahar

Theses

This study provides the analysis for the optimal design of a conventional vehicle suspension system, consisting of a sprung mass (vehicle body) and two unsprung masses (wheel frame), accentuated by the implementation of a damped absorber to the unsprung masses. Further, the effect of the c.g. (center of gravity) location of the vehicle body is investigated. A two dimensional, four degrees of freedom linear model is chosen. Randomly profiled terrain is assumed to impart hyperbolically distributed stationary vertical random displacements to the front and rear wheels. For generalization, nondimensional design parameters are selected. Criteria for optimization include the tire-terrain normal …
