RAPID prototyping, REFUGEE camps, and DESIGN
More than 9 million people live in shelters globally, often in extremely hot climates. The thermal performance of shelters is often overlooked in the design process, despite being a consideration second only to safety in surveys of camp dwellers. Indeed, indoor temperatures exceeding 40°C have been recorded in previous studies. To aid in improving conditions, the roles building simulation and prototyping could play in forecasting shelter thermal performance as part of a new shelter design process are examined. The thermal performance of prototypes, built in the refugee camp of Azraq, was monitored during the hot season to evaluate four design approaches: (1) "blind" (uncalibrated) models, (2) calibrated models, (3) on-site design-variants and (4) off-site prototypes. These included the original shelter and six design alternatives implementing different overheating countermeasures. The results demonstrate that blind models are sensitive to the judgement of uncertainties but were still qualitatively useful. Model calibration vastly improves the agreement and significantly enhances forecasts of performance for the design alternatives, which remained similar across examined climates. It is therefore concluded that simulation and prototyping, either on-site or off-site, should be adopted within the shelter design process before mass deployment, to create better-living conditions for their dwellers.

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]

RAPID prototyping, BASKET making, and DESIGN
Focusing on a process where a designer embeds herself in craftspeople's workshops with the intention of 'learning from inside' and 'making together'; this paper proposes pathways for considering collaboration between designers and craftspeople via digital fabrication and weaving. The tension of forces that make weaving possible, act as an analogy for this collaboration as well as providing the title of the project as 'One Over, One Under'. The project proposes a mode of working and a spectrum of outcomes where the designer has a first-hand experience of production techniques, engages in a serious and continuous dialogue through making, and develops an intervention that also brings forth her own skill set (introducing digital fabrication and structural variations), thus transforming the conventions and boundaries between established roles and manufacturing techniques. An experiment that resulted in a series of objects considering both the technologies of production and the input of the designer, this process not only increases the potentials that crafts hold for the field of design, but it also offers possibilities of collaboration and a further articulation of the design act.

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.

FINITE element method, MAGNETS, FERROMAGNETIC materials, PROPERTIES of matter, and ELECTRICAL engineering
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]
