PROTOTYPES, BEHAVIORAL research, TECHNOLOGY, DISCIPLINE, and SCHOLARS
How do researchers search for knowledge? What are their behaviors and habits, and what technologies do they use? This article proposes that three design shifts - involving more human senses, enabling comparative and simultaneous viewing, and allowing immediate access to full content - will create a more fruitful research process for scholars who conduct a literature review, learn about a new topic in a related discipline, or catch up on advances in their field. The three proposed designed shifts were tested with prototyping. The systematic prototyping procedure is a method that can be employed by others to advance this field. [ABSTRACT FROM AUTHOR]
RAPID prototyping, MANUFACTURING processes, SPECIFICATIONS, MANUFACTURES, and SUPPLY chains
Despite the use of Additive Manufacturing (AM) technologies in a lot of applications including the production of some high-value products for end use, it is still very much an untapped potential. There is an increase in usage of AM technology for the manufacture of end-use products (Rapid Manufacturing (RM)) in recent years, but mass use of the technology in terms of speed, cost and quality, which is acceptable by the general consumer, is still not widely in existence today. The concept of RM as a viable production process is still not understood by many businesses/consumers, with thinking still dominated by the AM technologies for Rapid Prototyping (RP) applications. A key difference between RM and RP is in the supply chain. The RM supply chain is much more complicated than the RP supply chain. This research conducted a Delphi Study to identify the requirements or pre-requisites necessary for the use of RM technologies as a viable means to manufacture end used products (RM application of AM) in mass scale. The paper identifies 36 requirements or pre-requisites and classified them into various classes of importance in order to highlight their significance. In addition to supply chain issues, the requirements unearthed are factors or features about RM technology (equipment), materials and processes that need modification, upgrading or creation.

PROTOTYPES, TECHNOLOGY, ORGANIZATION, PROCESS control systems, SOFTWARE engineering, and METHODOLOGY
Prototyping has received a great deal of attention as an important design methodology. Current support technologies for prototyping environments are typically intended to increase the efficiency of the individual system builder. We propose a broader perspective for assessing the impact of support technology on prototyping processes. In developing this perspective, we present frameworks for prototyping processes, support technologies, and development performance. Prototyping is characterized from the behavioral perspectives of individual, social, and organizational processes--each of which must be considered in assessing impacts. Support technology is characterized by production, coordination, and organizational dimensions, each affecting prototyping processes and performance in unique ways. To assess the impacts of the process-technology linkages, measures are suggested for evaluating prototyping processes and products from task, social, and business perspectives. It is proposed that the primary determinant of performance impact is the fit between the prototyping processes and the support technology used. By combining a functional model of support technology with behavioral perspectives of the prototyping process, a better understanding of the impacts of technology on prototyping effectiveness is obtained.

The University of California, Berkeley, has developed the Hyper system that provides a completely integrated synthesis environment for real-time prototyping of datapath-intensive architectures, such as those used in high-performance, real-time systems in telecommunications, speech, video and image processing. Synthesis for real-time applications is defined as the hardware implementation with the least area, given an input computational graph, a number of real-time constraints and a hardware cell library. Hyper can generate a simulation model of the flow graph at any point, allowing the correctness of the executed operations to be verified and their effects on such performance parameters as the signal-to-noise ratio to be checked. The overall synthesis procedure in Hyper is implemented as a search process; new solutions are proposed by the system by executing such basic moves as adding or removing resources, changing the time allocation for different subgraphs in the algorithm, and applying an optimizing graph transformation.

General Electric Co's Diodes hardware prototype production system supports testing and debugging of digital-signal processor (DSP) designs as well as the fast and economical production of hardware prototypes. Diodes software partitions the DSP system into predefined function blocks, assembles it using advanced packaging technology, tests it and debugs it; it can be used as a standalone system or as part of a larger electronic environment. The algorithm is coded by the user in a high-level algorithmic language; the algorithm is translated into a structural specification by the synthesis software as a multichip module suitable for high-density interconnection (HDI) fabrication. HDI fabrication allows a prototype DSP module to be ready for testing in only a few days at a moderate cost compared to the cost of custom very-large-scale-integration (VLSI) design.
COMPUTER software, COMPUTERS, COMMERCIAL markets, ELECTRONIC industries, TECHNOLOGY, and EMBEDDED computer systems
With the integration of computer technology, consumer products, and communication facilities, the software in an embedded system now accounts for as much as 70% of total system functionalities. In this work, we propose a complete methodology called ESSP (Embedded Software Synthesis and Prototyping) for the automatic design of embedded software. Several issues are solved, including software synthesis, software verification, code generation, and system emulation. To avoid design errors, a formal approach is adopted because glitches in embedded software are intolerable and very expensive or even impossible to fix. Complex-choice Petri nets are used to model embedded software, which are then synthesized using an extended quasi static scheduling algorithm. The final generated C code is prototyped on an emulation platform, which consists of an 89C51 microcontroller for executing the software, an FPGA chip for programming the hardware for different applications, and some input/output devices. Two application examples are used to illustrate the feasibility of the ESSP methodology. [ABSTRACT FROM AUTHOR]

COMPUTER software, SYSTEMS software, COMPUTER science, COMPUTER software development, TECHNOLOGY, and GRAMMAR
Languages are critical to the successful use of computers in solving problems. Languages are useful not only in specifying how to compute solutions, but in conceptually understanding and describing solutions. Recent advances in software technology lie mostly in more sophisticated tools and models of computation as reflected in languages. The usefulness of language is difficult to overstate—a computer's sophistication depends directly on the sophistication of the languages of the computer's editors, compilers, and command interpreters. Perception of this usefulness has led to much research in the classification, characterization, and recognition of languages. In spite of the major successes of language theory, translator construction still remains a black art of computer science. The regular expressions, terminals, nonterminals, and grammars in which the translator writer thinks are nowhere to be found in the translators he writes, except perhaps in comments and as abstract entities associated with particular pieces of code. Here the uses and advantages of a language tailored specifically for the description and construction of translators are considered. [ABSTRACT FROM AUTHOR]
RAPID prototyping, TECHNOLOGY, MASS production, THREE-dimensional printing, and MACHINE molding (Founding)
Amid the general euphoria about the opportunities presented by additive manufacturing, there are those who take a more level-headed view of the disruptiveness of the technology. According to Nigel Flowers, United Kingdom managing director of Sumitomo (SHI) Demag, for example, injection molding and additive manufacturing are more complementary to one another than competitors.

Researchers at Sandia National Laboratory in Albuquerque, NM, are ecstatic over the endless possibilities of rapid prototyping for speeding up computer-aided design and manufacturing. Their report at the Rapid Prototyping and Manufacturing Conference in May 1993 on the modeling of a bicycle crank arm highlighted the advantages of rapid prototyping over traditional techniques. The experiment, which used the stereolithography technique and the selective laser sintering approach, yielded production-like prototypes in just five days. Conventional methods usually take several months. In a related development, the process' speed improvement was instrumental in winning over a customer of Sundstrand Aerospace's Electric Power Div. The customer had asked for a current-transformer/electromagnetic interference module to be repaired in four months' time. Rapid prototyping enabled Sundstrand to make a model one month after the project's start.

Present software development methods are not sufficient to handle the fast growing demand for larger systems and higher-quality software. Rapid prototyping may be the solution for improved programming productivity and software reliability. PSDL is a system description language for describing prototypes of real-time software systems. PSDL supports rapid prototyping based on abstractions and reusable software components. It is useful for very large real-time systems and for prototyping typical Ada applications. Information is provided on control constraints, computational models, timing constraints, hierarchical constraints, requirements for the hyperthermia system, prototyping methodology and the support environment.
