IEEE Design and Test of Computers, 1989
The authors describe scan path, NEC's implementation of the scan design approach to design for testability. Designers at NEC have found that scan path greatly contributes to the reduced testing and maintenance cost of their products. The authors discuss several implementations of scan design and compare four implementations, including two scan-path ...

Automated design of a three-dimensional fishbone antenna using parallel genetic algorithm and NEC
IEEE Antennas and Wireless Propagation Letters, 2005A new antenna configuration, named the three-dimensional fishbone antenna (3DFA), as an improvement of the conventional fishbone antenna, is presented in this letter. It consists of dipoles that may be of nonuniform lengths with unequal spacing and are allowed to tilt in haphazard directions. To achieve a high endfire gain and good impedance match, the

Sociotechnical Theory and NEC System Design [PDF]
, 2007 The term 'Sociotechnical' is much more than merely a buzzword, it is a set of theories and concepts that seek to jointly optimize the co-evolution of organizations and technology. In this paper we show how the specification of a set of basic sociotechnical principles (responsible autonomy, adaptability and meaningfulness of tasks) could help to create ...

Speeding up NEC electromagnetic simulation using GPU technology for antenna design problems
International Journal of Computing Science and Mathematics, 2013Graphics processing units GPUs have increasingly become an attractive alternative to central processing unit CPU for some of compute-intensive and parallel tasks. This paper presents application of GPU technology to speed up numerical electromagnetic code NEC electromagnetic simulation. Then the GPU-NEC was used to evolve antenna.

NEC design compliance, system protection and Arc Flash Hazard
IEEE Transactions on Industry Applications, 2012The National Electric Code specifies limits on settings of transformer overcurrent protective devices that directly affect system protection. However, compliance with NEC design guidelines does not assure adequate system protection. The result can be zones of poor or non-existent protection and “Extreme Danger” Arc Flash Hazard Ratings (AFH).

Neonatal Intensive Care Workflow Analysis Informing NEC-Zero Clinical Decision Support Design
CIN: Computers, Informatics, Nursing, 2022Decision support in neonatal ICUs is needed, especially for prevention and risk awareness of the devastating complication of necrotizing enterocolitis, a major cause of emergency surgery among fragile infants. The purpose of this study was to describe the current clinical workflow and sociotechnical processes among clinicians for necrotizing ...

NEC contracts for design–build–operate contracts
Proceedings of the Institution of Civil Engineers - Management, Procurement and Law, 2013The NEC Engineering and Construction Contract (ECC) is a popular choice for construction and design-and-build contracts in the UK and South Africa. They are also increasingly by being used elsewhere in the world, for example in New Zealand and in Hong Kong. The NEC family of contracts is specifically designed for international use.

Design methodology and tools for NEC electronics' structured ASIC ISSP
Proceedings of the 2004 international symposium on Physical design, 2004In this paper, we describe a design methodology and tools for NEC Electronics' structured ASIC, Instant Silicon Solution Platform (ISSP), which is being developed to fill the gap between FPGAs and standard cell-based ASICs. The ISSP has a unique regular-fabric architecture designed to achieve both a short time to production and high-performance LSI ...

Electric power systems design: The NEC and the IEC approach
Proceedings of 1996 IAS Industrial and Commercial Power Systems Technical Conference, 2002The purpose of this paper is to compare the techniques and results obtained when a general industrial or commercial building power electrical system is prepared using the United States National Electrical Code/spl copy/ (NEC/spl copy/) and the International Electrotechnical Commission (IEC) Standards.
