A Conceptual Design Of A Catalogue Subsystem For A Student Advisory System, Claudette Captoria Browder Watson

Electronic Dissertations and Theses

At Southern University, students are assigned to faculty advisors with responsibilities for guiding the student in selecting courses to complete the requirements for a selected degree. Large departments with dynamic curricula changes encounter problems in ensuring that all students are properly advised in their respective degree programs. In an effort to address the advisement problem, an ad hoc University committee was named to study the problem and the findings and suggestions for enhancement were reported to the University administration. The Computer Science Department faculty wrote a proposal for an On-Line Computerized Academic Advisement System (CAAS) to address these problems which …

An Aeration Duct Design Model For Flat Grain Storage, Thomas C. Bridges, Douglas G. Overhults, Samuel G. Mcneill, G. M. White

Biosystems and Agricultural Engineering Faculty Publications

Traditionally most grain is stored in circular type bins which provide a convenient means for handling and management. With the excess grain production and government loan programs of the past few years, some producers have used rectangular structures and covered piles to complement their round storages. The recommended management practices used with round bins are still required in those alternative storages and may be more critical in obtaining a quality end product.

One such recommended practice used with round bins is aeration. This practice is used to maintain a uniform temperature in the grain mass, preventing condensation and "hot" spots …

Computer Use In The Warren County Riii School District: A Proposal For The Implementation Of A Computer Lab Program In The Elementary School, Debbie Reese

Theses

A problem faced by many schools in the 1980s is how to approach computer ir1struction in the elementary grades. Schools have moved into a new technological realm with the advent of the modern microcomputer. The focus of this project was to investigate current trends in computer education in the elementary grades in respect to computer placement within the schools and content of computer education programs. The paper addresses, specifically, the lack of a computer program in the Warren County RIII School District and the rationale for developing a computer lab in the elementary school. An interim plan is also proposed, …

Dc-Free Coset Codes, Robert H. Deng, M. A. Herro

Research Collection School Of Computing and Information Systems

An upper bound on the bit-error probability (BEP) of a linear cyclic code over GF(2l) with hard-decision (HD) maximum-likelihood (ML) decoding on memoryless symmetric channels is derived. Performance results are presented for Reed-Solomon codes on GF(32), GF(64), and GF(128). Also, a union upper bound on the BEP of a linear cyclic code with either hard- or soft-decision ML decoding is developed, as well as the corresponding bounds for the extended code of a linear cyclic code. Using these bounds, which are tight at low bit error rate, the performance advantage of soft-decision (SD) ML and HD ML over bounded-distance (BD) …

Atamm Multicomputer System Design, William Robert Tymchyshyn

Electrical & Computer Engineering Theses & Dissertations

The Algorithm To Architecture Mapping Model, or ATAMM, is a graph theoretic design methodology that has been created to resolve design and performance issues involved with concurrent processing. Petri-net marked graphs are used to represent the computational environment.

This thesis describes the development of a multicomputer system which will operate within the bounds specified by the ATAMM model. The system is first designed and implemented using the framework of standard multicomputer design theory. A validation is then performed by the comparison of the system's computational performance to results predicted by ATAMM. This validation is shown to be successful for three …

Using The Bat: A Six Dimensional Mouse For Object Placement, Colin Ware, Danny R. Jessome

Center for Coastal and Ocean Mapping

Placement in space is inherently six dimensional. An object can be translated in x, y and z cartesian coordinates, and it can be rotated about three axes to change its orientation. A six dimensional sensor I\I(/S conj/gured as a one button six dimensional mouse (which we call a bat) and interfaced with an IRIS workstation thus creating an environment for investigating the problems of object placement. A sojiware workbench was built which allows the manipulation of hierarchical scenes displayed on a monitor. The features of the workbench are described together with experiences using the bat in a variety of interaction …

Consequently, …

Implementing Ray Tracing Algorithm In Parallel Environment, Tjah Jadi

Dissertations and Theses

Ray tracing is a very popular rendering algorithm in the field of computer graphics because it can generate highly-realistic images from three-dimensional models. Unfortunately, the computational cost is very expensive. To speed up the rendering process we present both static and dynamic scheduling (balancing) strategies for a multiprocessor system. Hence, the load balancing among the processors is the most important problem in parallel processing. The implementation of the algorithm is based on a modified octree structure.

Using A Partial Order And A Metric To Analyze A Recursive Trace Set Equation, Jan Tijmen Udding, Tom Verhoeff

All Computer Science and Engineering Research

In Trace Theory the notion of a process is defined in terms of a set of finite-length traces over an alphabet. These processes are used as the semantics for a program notation. The program text for a recursive component naturally gives rise to an equation over trace sets. This paper takes two approaches at the analysis of that equation. The first approach is based on a partial order and it concentrates on the projection operator for processes. This yields a condition under which the greatest solution of that equation can be approximated by iteration. The second approach introduces a metric …

Shadow Pattern Simulator, Roberto A. Brown

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This paper describes an interactive computer program that can be used as a design tool in assessing the shading effects of trees in relation to buildings. The program determines the area and position of the shadow cast by a tree or group of trees on a surface of a building which can have any orientation. The program outputs numerical and graphical hourly results at any time of the day, for any day of the year, at any location on the earth, for any relative positioning between the tree and building, and estimates percent irradiation reductions on building surfaces resulting from …
