A Theoretical Investigation of Topological Insulator Nanostructures

The topology of the electron wavefunctions in certain band insulators can give rise to novel topological phases. Materials harbouring such topological phases are termed topological insulators (TI). A gapped bulk electronic spectrum, described by a topologi ...

Kron reduction methods for plug-and-play control of AC islanded microgrids with arbitrary topology

Giancarlo Ferrari Trecate

In this paper, we provide an extension of the scalable algorithm proposed in (Riverso et al., 2015) for the design of Plug-and-Play (PnP) controllers for AC Islanded microGrids (ImGs). The method in (Riverso et al., 2015) assumes DGUs are arranged in a loa ...

Comparative studies of electrostatic turbulence induced transport in presence of resonant magnetic perturbations in RFX-mod

Nicola Vianello

Three-dimensional non-axisymmetric magnetic fields are purposely applied to toroidally symmetric fusion plasmas in order to modify transport of heat and particle fluxes to the plasma-facing components (PFCs), and specifically to control and suppress edge l ...

Planck 2013 results. XXVI. Background geometry and topology of the Universe

Julien Lesgourgues, Jason Douglas McEwen, Fabio Finelli

The new cosmic microwave background (CMB) temperature maps from Planck provide the highest-quality full-sky view of the surface of last scattering available to date. This allows us to detect possible departures from the standard model of a globally homogen ...

Computing Accurate Performance Bounds for Best Effort Networks-on-Chip

Giovanni De Micheli, Luca Benini, Srinivasan Murali, Federico Angiolini, Hamid Sarbazi-Azad, Dara Rahmati

Real-time (RT) communication support is a critical requirement for many complex embedded applications which are currently targeted to Network-on-chip (NoC) platforms. In this paper, we present novel methods to efficiently calculate worst- case bandwidth an ...

Ideal MHD stability of helically symmetric magnetic islands

Laurent Villard, Andrei Martynov

A new version of the MHD_NX code, that computes the ideal MHD stability of helically symmetric equilibria with arbitrary topology of magnetic surfaces, was applied to the investigation of equilibrium magnetic islands in tokamak-like conditions. Any helical ...

Optimal filtering of an incremental second-order MASH11 sigma-delta modulator

Maher Kayal, Sylvain Maréchal, François Krummenacher

This paper describes an optimal filter design procedure for a cascaded sigma-delta modulator, starting with a block schematic of a second-order topology and deriving step by step the optimal decoder. The presented filter enhances the resolution of the MASH ...

Anisotropy effects on Rashba and topological insulator spin-polarized surface states: A unified phenomenological description

Marco Grioni, Emmanouil Frantzeskakis

Spin-polarized two-dimensional electronic states have been observed in metallic surface alloys with giant Rashba splitting and at the surface of topological insulators. We study the surface band structure of these systems, in a unified manner, by exploitin ...

Mitigating network congestion

Carolina Osorio Pizano

Congestion is a phenomenon that arises in a variety of contexts. The most familiar representation is urban traffic congestion. Nonetheless, phenomenons such as prison cell congestion, hospital bed blocking or, at a cellular scale, ribosome congestion, also ...
