Control upgrade for the TCV coils power supplies

Damien Fasel, Ugo Siravo, Jérémie Dubray, Nicolas Cherix

The Tokamak a` Configuration Variable (TCV) coil converters are fed, during the plasma pulse, by a flywheel generator (FG) providing the AC voltages few seconds before the plasma pulse. The synchronization with the 120 Hz frequency delivered by the FG, var ...

Low emission scenario for Europe powered by lifestyle changes

Vincent Moreau

Decarbonizing economic activities requires simultaneous behavioural and technological changes. At the household level, actions are straightforward, use public transit and stay off dairy and meat. The objective here is to estimate the overall climate benefi ...

Moire Flat Bands in Twisted Double Bilayer Graphene

Oleg Yazyev, Quansheng Wu, Seyedeh Fatemeh Haddadi Givi

We investigate twisted double bilayer graphene (TDBG), a four-layer system composed of two AB-stacked graphene bilayers rotated with respect to each other by a small angle. Our ab initio band structure calculations reveal a considerable energy gap at the c ...

A New Anti-Counterfeiting Feature Relying on Invisible Luminescent Full Color Images Printed with Lanthanide-Based Inks

Jacques-Edouard Moser, Roger Hersch, Anne-Sophie Chauvin, Julien Alexandre Andres

Europium and terbium trisdipicolinate complexes are inkjet printed onto paper with commercially available desktop inkjet printers. Together with a commercial blue luminescent ink, the red-emitting luminescent ink containing europium and the green-emitting ...

Improving FPGA Performance for Carry-Save Arithmetic

Paolo Ienne, Philip Brisk, Hadi Parandeh Afshar, Ajay Kumar Verma

The selective use of carry-save arithmetic, where appropriate, can accelerate a variety of arithmetic-dominated circuits. Carry-save arithmetic occurs naturally in a variety of DSP applications, and further opportunities to exploit it can be exposed throug ...

Data-flow transformations to maximize the use of carry-save representation in arithmetic circuits

Paolo Ienne, Philip Brisk, Ajay Kumar Verma

The increasing importance,of datapath circuits in complex systems-on-chip calls for special arithmetic optimizations. The goal is to automatically achieve the handcrafted results which escape classic logic optimizations. Some work has been done in the rece ...

Bio-inspired cellular machines : towards a new electronic paper architecture

Fabien Vannel

Information technology has only been around for about fifty years. Although the beginnings of automatic calculation date from as early as the 17th century (W. Schickard built the first mechanical calculator in 1623), it took the invention of the transistor ...
