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.

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]
TECHNOLOGY, RAPID prototyping, MANUFACTURING processes, SILICONES, and SILICONE rubber
German RepRap GmbH, a manufacturer of industrial 3D printers, has developed a platform for liquid silicone rubber that it claims makes it possible to 3D print heat-cured silicone parts using a high performance LSR. "The combination of the printer with the Dow 3D 3335 LSR is the only commercially available technology that heat cures the silicone rubber, the same curing method as used in the LSR manufacturing process".
