Design of Plastic Piece Parts
This paper describes a computer assisted design process originally developed at the University of Wyoming and now implemented in commercial software. In order to address the need for broadly...
Computer Aided Design of Monolithic Integrated Circuits
An algorithm has been developed to relocate the sites of electrical components and integrated circuits. The process simulates site location changes in order that path lengths of conductors...
Computerized Dynamic Human Factors Mannequins Assess and Create Products and Environments for an Aging Population
A PC-based human factors symbol library helps make designs accessible to a broad populace. The system and research results described were developed in three phases. Knowing that in order...
Constraint Based Design from Research into the Classroom
Design is constraint oriented; much of the design process involves the recognition, formulation and satisfaction of constraints. Constraints are continually being added, deleted and modified...
Stereolithography
Stereolithography is a three-dimensional printing process which produces accurate copies of CAD solid or surface models directly from CAD data. The process uses a moving laser beam, directed...
CAD/CAM: Reverse Engineering Applications
The reproduction of parts for which drawings or CAD files are not available has always caused engineering effort to be expended in a non-routine manner. The need for such a reverse engineering...
Frame Based Expert Systems?The Clear Choice for CAPP Systems
This paper gives a brief overview of Computer Aided Process Planning (CAPP) systems. We attempt to examine some of the representational problems specifically associated with production...
Safety in the Industrial Robot Environment
Safety requirements differ for applications with or without a human interface. The extent of human interface with the robot must be determined. Design of the robot, guarding, access, and...
Organization of Software Application Areas at The University of Michigan College of Engineering
This paper emphasizes the organizational aspects of bringing workstation use into a wide variety of courses through small interdisciplinary organizations within the College called sectors....
Implementation of CAE at UDC: A Pioneer Approach
This paper describes the initiation and implementation of Computer Aided Engineering at the department of electrical engineering of the University of the District of Columbia, using state-of-the-art...
Local Area Network Communications Testing
This paper presents the philosophy developed for benchmark communications testing in networks typical of CAD/CAM environments. Implementation of the test philosophy in a connectionless...
CAD and Video Teleconferencing Network Development
The Institute for Telecommunication Sciences is developing a prototype network to demonstrate the integration of a variety of services and methods for fulfilling Navy shipbuilding requirements....
Computer Networking Needs in Engineering Technology
This paper deals with the planning and implementation of a local area network at the University of Arkansas at Little Rock in the new $13 million Engineering Technology and Applied Science...
Loss of Carrying Capacity in Pipes?Transporting Softened Water with High pH
The increase in pipe roughness and loss in carrying capacity for water mains carrying high pH water is documented with over 20 field tests conducted in Austin, Texas. The data show that...
Global Risk Assessment: A Naive Look at Initiating Processes
Global risk assessment is finding those initiating processes which may cause harm to Earth systems (and ultimately the human species), their probability of occurrence, and the level of...
Continuous Sampling of Nonpoint Source Pollution
Sediment, nutrient, and other pollutant loads from storm water runoff in a small Texas watershed have been estimated using an initial strategy of periodic grab sampling and a revised strategy...
Nonpoint Source Loads and Phosphorus Budget for Lake LBJ
Nonpoint source loadings from stormwater runoff are a major contributor of pollutant loadings in many locations. A phosphorus budget is developed for Lake Lyndon B. Johnson (LBJ). Lake...
Evaluation and Selection of RBC Models for Design of Domestic Wastewater Facilities
This study evaluated three existing models commonly used for the design of Rotating Biological Contactors (RBC). Operating data from six RBC Treatment Plants located in eastern Massachusetts...
Proposal for Combining Expert Systems and Canal Design
Expert Systems can be combined with a computer aided design methodology to develop a cost effective canal system. The System should consider a feasible set of design alternatives to satisfy...
Economic Impacts of Storm Sewer Design Criteria
This paper discusses the selection of storm sewer design criteria and the resulting economic impacts. Using the Rational Method for calculating design flows, an investigation was made...
