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]
