On the sloshing free surface in the draft tube cone of a Francis turbine operating in synchronous condenser mode

François Avellan, Elena Vagnoni, Loïc Andolfatto

Hydropower plants may be required to operate in synchronous condenser mode in order to supply reactive power to the grid for compensating the fluctuations introduced by the intermittent renewable energies such wind and solar. When operating in this mode, t ...

Experimental benchmark of the NINJA code for application to the Linac4 H-ion source plasma

Minh Quang Tran, Stefano Mattei

For a dedicated performance optimization of negative hydrogen ion sources applied at particle accelerators, a detailed assessment of the plasma processes is required. Due to the compact design of these sources, diagnostic access is typically limited to opt ...

The DTT device: Power and particle exhaust

Holger Reimerdes

The possible scenarios at full power of the DTT (Divertor Test Tokamak) device with the standard single null (SN) and X divertor (XD) configurations have been analysed for the aspect of safely handling the power to be exhausted on the divertor targets. In ...

Physics and performance of the I-mode regime over an expanded operating space on Alcator C-Mod

Christian Gabriel Theiler, Yu Lin

New results on the I-mode regime of operation on the Alcator C-Mod tokamak are reported. This ELM-free regime features high energy confinement and a steep temperature pedestal, while particle confinement remains at L-mode levels, giving stationary density ...

Decentralized Optimal Projected Control of PV Inverters in Residential Microgrids

Florian Dörfler, Pulkit Nahata

In this paper, we consider the problem of overvoltage arising in PV residential microgrids due to excessive power injection into the grid by the PV generators. We propose a decentralized optimal integral controller to curtail excess active power in order t ...

Penciling A Triboelectric Power Source On Paper

Jürgen Brugger, Xiao Sheng Zhang

We present a novel triboelectric nanogenerator (TENG) based on a paper-Teflon configuration fabricated by an easy and cost-efficient process. Carbon electrodes were hand-drawn by means of a graphite pencil on commercial paper cards, and the conductivity wa ...

Side-Channel Attacks on Threshold Implementations using a Glitch Algebra

Serge Vaudenay

Threshold implementations allow to implement circuits us- ing secret sharing in a way to thwart side-channel attacks based on prob- ing or power analysis. It was proven they resist to attacks based on glitches as well. In this report, we show the limitatio ...

Information-based recognition: TED talks and the institutional fabric of valuable innovation

Gianluigi Viscusi, Heidi Christina Gautschi

Information has long been considered a commodity, something that organizations and individuals can trade for financial gain (Chandler, 1993). And, the networks via which information flowed have long had a conflictual relationship with power and control, bu ...
