Substantial technical and economic benefits are obtainable by fitting a visual communication system to a specific application. Some of the considerations involved in such adaptation are discussed in this paper. An experimental system to demonstrate the specific adaptation to the problem of signature verification in a savings bank is described. It is shown that satisfactory images can be transmitted over a 5‐kilocycle sound program circuit in 5 seconds. This result is obtained by reducing both the area scanned by the transmitter and the resolution of the reproduction to the minimum required for this application.
An overview ofthe radiographic capabilities with emphasis on electronic image detection and processing at the Los Alamos National Laboratory is presented. Fixed facilities and portable x-ray sources and imaging systems make up the Los Alamos capability. Examples of imaging with large area amorphous silicon imaging panels, a portable computed tomography system, high speed x-ray imaging applications and equipment, and small area, high resolution imagers are given. Radiographic simulation and reverse engineering from radiographic images to computer aided design files and solid models is also presented.
Customized product realization allows piece parts to be assembled in an optimum way. For example, striving to optimize design parameters during production by either manufacturing or assembling one part to compensate for design deviations present in another part of the assembly. This approach minimizes rejected parts in production because it provides a way to use parts that normally would have been scraped. It also maximizes part reuse in post-production by providing a logical way to determine what optimal piece parts to use in an assembly from an inventory of possible piece parts.As-Built Engineering provides a methodology for fully characterizing the enduring stockpile. This not only allows for optimally assembled systems and enhanced analysis simulations based on actual product characteristics, but also allows for the monitoring of an assembly's maturation. All post-production activities involving a product would be defined and captured in an as-built model. This has implications in both Surety and Surveillance. As-built models contain the high fidelity product information that can be used for maintenance, simulations, quality assurance, and design analysis.Benefits of As-Built Engineering include the following: 1. can be implemented without effecting mission critical activities, 2. is robust and allows new processes, technologies, and equipment to be introduced into a product realization infrastructure in a quantifiable manner, 3. provides a way to characterize product information that in turn allows assembly optimization -both during production and in post production. 4.For archival and surveillance, allows a methodology for knowing what you have so that changes in a product can be measured. 5. provides high fidelity product representations that can be used as input into emerging analysis and simulation tools being envisioned by ASCI. These high fidelity representations accurately describe each individual assembly and thus provide a basis for measuring aging and application effects. AbstractAs-Built Engineering is a product realization methodology founded on the notion that life-cycle engineering should be based on what is actually produced and not on what is nominally designed. As-BuiltEngineering is a way of thinking about the product realization process that enables customization in mass production environments. It questions the relevance of nominal based methods of engineering and the role that tolerancing plays in product realization. As-Built Engineering recognizes that there will always be errors associated with manufacturing that cannot be controlled and therefore need to be captured in order to fully characterize each individual product's unique attributes. One benefit of As-Built Engineering is the ability to provide actual product information to designers and analysts enabling them to verify their assumptions using actual part and assembly data. Another benefit is the ability to optimize new and reengineered assemblies. Princ@als ofAs-Built Engineering Cmter for Advanced Engineering Technology LA...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
