During the last few years the performances and therefore the complexity of the variable-speed drives as well as those of the modern power plants have considerably increased. Consequently, an optimized design of these equipments requires suitable numerical simulation tools in order to guarantee the feasibility and the performances of such equipments in steady-state or transient operation. More p...

StarBED is a network testbed begun in 2002 focused on running actual program code for software and hardware implementations. As hardware technologies develops, its facilities such as PCs and network equipments have been updated and we additionally developed SpringOS, a software support suite consisting of numerous program modules. The performance of StarBED and SpringOS increases as their equip...

This paper describes two different approaches to use Near Field Communication (NFC) enabled mobile phones in a ticketing system dedicated to event management: (i) a offline version where some equipments are not connected to the Internet ; (ii) a online version where an Internet connection is available on all the equipments composing the infrastructure. These two propositions are compared so as ...

Modern ac-dc transfer equipments can operate up to 1 GHz at least. These equipments and the related ac-voltage measurements may be attractive for calibrating high frequency power sensors in term of ac-dc transfer difference instead of effective efficiency. Furthermore, below 30 MHz, the ac-voltage standard can be also used as powerful alternative and complement to the microcalorimeter technique...

A famous instance is a picture of a receipt taken by a customer at a hunting and fishing chain store called Cabela. The receipt listed a 2.3%“medical excise tax,” which was supposedly levied as part of the Affordable Care Act. This was seen as evidence that there is a hidden tax that consumers are paying for the ACA. The store later cleared this up as being a “software glitch” on their part. Th...

Multihop network is an approach utilizing distributed wireless stations for relaying. In this system, area size, coverage and total transmit power efficiency can be improved. It is shown by computer simulations that the cooperative relaying scheme provides transmit diversity effect, and can offer much better performance compared with that of non-cooperation case. To confirm this superior perfor...

This paper addresses Model Based Diagnosis for the test of avionics systems that combines aeronautic computers with simulation software. Just like the aircraft, those systems are complex since additional tools, equipments and simulation software are needed to be consistent with the test requirements. We propose a structural diagnostic framework based on the lattice concept to reduce the time of...
