Free boundary equilibrium in 3D tokamaks with toroidal rotation

Wilfred Anthony Cooper, Olivier Sauter, Minh Tâm Tran, Jonathan Graves, David Pfefferlé, Daniele Brunetti, Jonathan Marc Philippe Faustin, Madhusudan Raghunathan

The three-dimensional VMEC equilibrium solver has been adapted to numerically investigate the approximate toroidal rotation model we have derived. We concentrate our applications on the simulation of JET snakes and MAST long-lived modes under free boundary ...

Efficient multistage secret sharing scheme using bilinear map

Mitra Fatemi, Reza Ghasemi

In a multistage secret sharing (MSSS) scheme, the authorised subsets of participants could recover a number of secrets in different stages. A one-stage multisecret sharing (OSMSS) scheme is a special case of MSSS schemes in which all the secrets are recove ...

An Economic Model Predictive Control scheme with terminal penalty for continuous-time systems

Colin Neil Jones, Andrea Alessandretti

In this paper, convergence and performance properties of a sample-data continuous time model predictive control (MPC) scheme with economic performance index are developed. In particular, we provide sufficient conditions for convergence of the close loop st ...

Formation of a three-dimensional plasma boundary after decay of the plasma response to resonant magnetic perturbation fields

Holger Reimerdes

First time experimental evidence is presented for a direct link between the decay of a n = 3 plasma response and the formation of a three-dimensional (3D) plasma boundary. We inspect a lower single-null L-mode plasma which first reacts at sufficiently high ...

Application of Power Time-Projection on the Operator Splitting Coupling Scheme of the TRACE/S3K Coupled Code

Rakesh Chawla, Damar Canggih Wicaksono, Hakim Ferroukhi, Omar Zerkak

This paper reports refinement studies on the temporal coupling scheme and time-stepping management of TRACE/S3K, a dynamically coupled code version of the thermal-hydraulics system code TRACE and the 3D core simulator Simulate-3K. The studies were carried ...

Masking vs. Multiparty Computation: How Large Is the Gap for AES?

Sebastian Faust

In this paper, we evaluate the performances of state-of-the art higher-order masking schemes for the AES. Doing so, we pay a particular attention to the comparison between specialized solutions introduced exclusively as countermeasures against side-channel ...

On the Role of the Necessary Conditions of Optimality in Structuring Dynamic Real-Time Optimization Schemes

Dominique Bonvin

In dynamic optimization problems, the optimal input profiles are typically obtained using models that predict the system behavior. In practice, however, process models are often inaccurate, and on-line adaptation is required for appropriate prediction and ...
