Reflections On Solid Modeling In Cad/Cam System, Yuh-Hwa Chyr

Theses

In this thesis, we will first study the mathematical fundamental for geometric modeling. It includes modeling space, representation scheme, and various characteristics for solid modeling. Then we discuss how a solid modeling system is integrated into an overall CAD/CAm system. What functions it performs, and what fuctions must be performed with other parts of the CAD/CAM systems. And how data can be transfered between solid modeling system and other CAD/CAM system.

Solid modeling has created a new era in CAD/CAM. A solid model is an unambiguous, three-dimensional, geometric representation of a design. The more design information a model can represent, …

An Image-Capable Interprocessor Link Communications Protocol, Robert W. Brown

Theses

Image-capable interprocessor links often require the use of specialized communications protocols due to the large amounts of data that can be transmitted and the high speeds at which the data can be transferred. Without a set of generalized image-capable communications rules, these protocols are commonly customized to each interprocessor link application. The image-capable interprocessor link communications protocol described in this paper (IPLIMP) has been designed to limit the need for such customization at a low level. In order to accomplish this, IPLIMP provides simple methods for synchronizing and controlling link operations, sending and receiving data, downloading additional protocol layers, and …

To properly understand these windows it is necessary to first take a brief but close look at Jesse Shepard, to understand what kind of man he was in 1887 when he came to San Diego; next to take a …

White Chief: The Story Of Edward H. Davis, Charles Mitchell Hudgins

Theses

With Mother Earth for a couch, To sleep under the fragrant conifers; To breath the purity of the ranges; To watch the procession of the constellations; To listen to the music of the wind harps of the sierras; To leave care, worry, responsibilities behind us; To be in harmony with nature at all times; To live simply, to think severely, the love deeply, to be content; And to learn patience and tolerance from the mighty mountains; That me thinks is to be happy. Edward H. Davis Mesa Grande August 26, 1933

St. Charles County Juvenile Court Diversion Programs, Charles W. Hortmeier

Theses

It has been theorized that the less formal and penetrating a youngster's contact with the Juvenile Justice System, the smaller his or her likelihood of continued delinquency.

The Impact Of Gender Differences On The Ethical Conduct Of Corporate Middle Management, Daniel W. Kemper

Theses

This thesis will focus on the study of business ethics and the impact gender has upon the ethical decisions of corporate middle management .

Research has attributed the lack of ethics in businessmen to a decline in moral standards . Because this condition seems to be the rule rather than the exception, it becomes necessary to focus more clearly on the corporate system and the moral development of the individuals who make up this system.

Over the years moral development has been the subject of controversy as many theorists have developed their own ideas as to why people behave morally. …

The Architectural Theme In Painting, Allene Jones Ricker

Theses

The architectural theme has been used in painting in varying ways as decoration, in landscape, as composition and as abstraction. From the first century until the Renaissance, architecture was used by artists as decoration or as a backdrop, setting the stage and framing the figures. Architecture as subject matter continued to evolve in a manner nearly parallel to the development of the landscape. Architecture in the form of Roman ruins, for example, was used in picturesque landscapes.

Architecture in landscapes developed into townscapes. In both Holland and Italy the townscape was painted extensively. The Venetian view painters were interested in …

A Report On Debugging Networked Real-Time Multi-Microprocessor Systems, Anandi Krishnamurthy

Theses

Software development in networked real-time multi-microprocessor control systems is made difficult by the real-time constraints and parallel processing inherent in such systems. Software development in general, and debugging, in particular, of networked real-time multi-microprocessor systems is discussed. A tool that is a part of a debugger for such a system is described. The tool runs on a workstation with a passive user-interface and provides high-level access to the control software. The commands supported by the tool are analyzed. The software architecture of the tool is documented using data flow diagrams, a dictionary, file formats and pseudo-code.

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 …

Countywide Police Simulation System Cops, Craig J. Mcdonald

These include Bayesian probabilities, Mycin confirmation theory, fuzzy set theory, Dempster-Shafer's theory of evidence and a theory of endorsements. A toolkit to apply uncertainty processing in PROLOG expert systems is developed using fuzzy set theory as the basis for uncertainty reasoning and representation. The concepts of fuzzy logic and approximate reasoning are utilized in the implementation. The …

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 …
