FINITE element method, PERMANENT magnet generators, and STATORS
Multi-turn resolvers are employed in the applications that high reliability; high accuracy and absolute position measurement are required, simultaneously. They are basically consisted of two individual resolvers in a common frame. In this paper a novel sinusoidal air-gap length multi-turn resolver is proposed. The rotor shape and the winding configuration are designed to achieve single-speed and multi-speed operations using a single rotor and a single stator core. Furthermore, some constraints are laid down and discussed in such a way that the performance of two resolvers has no interference with each other. All the mathematical calculations are validated using time stepping finite element analysis. Finally, a prototype of the sensor is built and tested. Experimental measurements are used to verify the analytical and finite element discussions. [ABSTRACT FROM AUTHOR]
The article informs that the periodical has partnered with Framer to try and understand how designers use prototyping in interaction design projects and help them to compile a free to access report. It mentions that the partnership help give a proper understanding of whether prototyping is growing within interaction design and able to look in detail at whether prototyping helps to communicate ideas both within organisations and to clients as well as if it improves outcomes for customers.
COMPUTER software, PROTOTYPES, TESTING, COMPUTER simulation, and DESIGN
A prototyping and simulation tool that supports the development of distributed programs is described. This tool, called Jems, forms a part of Jade, a distributed software prototyping environment. The Jade environment provides tools for the design, implementation, debugging, testing, maintenance, and performance analysis of distributed, concurrent programs. Novel features of Jade include the support of: multi-lingual distributed programs; flexible monitoring of inter-process communication; multiple views into executing programs via a window system; graphical animation of executing programs; and the prototyping of distributed software. This paper presents an overview of the Jade environment, describes the distributed software prototyping tool, and outlines the status of the project. [ABSTRACT FROM AUTHOR]

Prototype, Algebraic Languages, Distributed Systems, Formal Languages, Semantics, Real-Time System, Design, Specifications, Programming Language, and Programming languages -- Design and construction
The PSDL prototyping language for hard real-time systems is described. The semi-graphical language provides a data flow notation as well as application-orientation timing and control constraints for describing a system as a hierarchy of networks of processing units that communicate through data streams. The basic PSDL constructs are defined in terms of algebraic high-level Petri nets, combining algebraic specifications of abstract data types with the concurrency and process concepts of Petri nets. The high-level Petri nets model the system's casual and timing behavior. The data abstraction facilities define the meaning of PSDL data types. The net semantics provide a basis for applying the analysis techniques and tools of high-level Petri nets.

This paper presents the design, prototyping, and analysis of a relatively small and cheap axial-flux three-phase coreless permanent- magnet generator. The excitation of the machine is done by rectangular flat shaped neodymium-iron-boron magnets. A two-dimensional model of the machine is analyzed with finite-element software to obtain the machine parameters. One special feature of the constructed generator is in the design and prototyping of nonferromagnetic holders to counteract centrifugal forces acting on magnets, especially at high speeds. By implementing the nonferromagnetic holders, one can expect to construct high-speed axial-flux permanent-magnet generators at low cost. [ABSTRACT FROM AUTHOR]

NEW product development, RAPID prototyping, STRATEGIC planning, ECONOMETRICS, and FACTORIES
Investments in design play a potentially significant role in new product development (NPD) although there is little unanimity on the most appropriate or effective design strategy. Previous case-study based studies have identified three alternative design strategies for NPD: design used as a functional specialism, design used as part of a multi-functional team and designer-led NPD. Using data on a sample of Irish manufacturing plants over three periods we are able to examine the effectiveness of each of these three design strategies for NPD novelty and success. Our analysis suggests that design is closely associated with success in NPD performance regardless of the type of strategy pursued. Adopting designer-led NPD, however, is associated with a much greater NPD performance than more functionally-oriented strategies. The effects of design on NPD outcomes are also strongly moderated by other plant characteristics. For example, the beneficial role of design on NPD outputs is only evident for plants which also engage in R&D. Also, while both small and larger plants do gain from using design as a functional specialism and as part of multi-functional teams, the additional benefits of design-leadership in the NPD process are only evident in larger plants.

Prototyping can be applied to building computer information systems, either as an alternative or as a supplement to the traditional approach of systems design and development. The traditional system, which involves developing specifications before any programming is done, often results in both the user and the data processing staff shifting the blame, with no one taking the blame for inadequate systems. In contrast, prototyping uses highly efficient programming languages and other software tools to develop a model of the intended system shortly after discussion of the initial requirements. The model takes the place of written technical specifications. The data processing staff can demonstrate the prototype, get user feedback and make changes until the system is complete.
