Euler-Poincare Approaches to Nematodynamics

Tudor Ratiu, François Gay-Balmaz, Cesare Tronci

Nematodynamics is the orientation dynamics of flowless liquid-crystals. We show how Euler-Poincar, reduction produces a unifying framework for various theories, including Ericksen-Leslie, Luhiller-Rey, and Eringen's micropolar theory. In particular, we sho ...

A Flexible In Situ Power Monitoring Unit for Environmental Sensor Networks

Alcherio Martinoli, Alexander Bahr, William Christopher Evans

Wireless radios are a great consumer of energy in sensor networks. Retrieving data from a remote deployment in an energy-efficient fashion is a difficult problem, and while solutions have been proposed in literature, real-world systems typically implement ...

The weighted averages algorithm revisited

Juan Ramon Mosig

The classic weighted averages (WA) algorithm for the evaluation of Sommerfeld-like integrals is reviewed and reappraised. As a result, a new version of the WA algorithm, called generalized WA, is introduced. The new version can be considered as a generaliz ...

Dirac Structures, Nonholonomic Systems And Reduction

Tudor Ratiu, Madeleine Jotz

The reduction of nonholonomic systems is formulated in terms of Dirac reduction. An optimal reduction method for a class of nonholonomic systems is formulated. Several examples are studied in detail. ...

Interfacial Self-Assembly of Water-Soluble Cationic Porphyrins for the Reduction of Oxygen to Water

Hubert Girault, Astrid Johana Olaya Avendano, Pierre-François Marie Brevet

Meet at the border: Assembly of the water-soluble cobalt tetrakis(N-methylpyridinium-4-yl)porphyrin [CoTMPyP]4+ at soft interfaces is enhanced and stabilized by its interfacial interaction with the lipophilic anion (C6F5)4B−. The supramolecular structure t ...

Gold catalysis at the gas-solid interface: role of the support in determining activity and selectivity in the hydrogenation of m-dinitrobenzene

Fernando Cardenas Lizana

The catalytic gas phase hydrogenation of m-dinitrobenzene (1 atm, 423 K) over laboratory synthesised (1 mol%) Au supported on Al2O3, TiO2, Fe2O3 and CeO2 and a reference Au/TiO2 (World Gold Council) has been investigated. The catalysts were prepared by dep ...

Infinite integrals with the weighted averages algorithm

Juan Ramon Mosig

A new version of the weighted averages (WA) algorithm, called generalized WA, is introduced. Generalized WA exhibit a more compact formulation, devoid of iterative and recursive steps, and a wider range of applications. It is more robust, as it provides a ...

Global Functional Connectivity Deficits in Schizophrenia Depend on Behavioral State

Roy Salomon

Schizophrenia is a devastating psychiatric illness characterized by deterioration of cognitive and emotional processing. It has been hypothesized that aberrant cortical connectivity is implicated in the disease (Friston, 1998), yet previous studies of func ...

A DRAM Centric NoC Architecture and Topology Design Approach

Giovanni De Micheli, Luca Benini, Srinivasan Murali, Ciprian Seiculescu

Most communication traffic in today’s System on Chips (SoC) is DRAM centric. The NoC should be designed to efficiently handle the many-to-one communication pattern, funneling to and from the DRAM controller. In this paper, we motivate the use of a separate ...

On the Reduction of Atomic Broadcast to Consensus with Byzantine Faults

André Schiper, Martin Hutle, Zarko Milosevic

We investigate the reduction of atomic broadcast to consensus in systems with Byzantine faults. Among the several definitions of Byzantine consensus that differ only by their validity property, we identify those equivalent to atomic broadcast. Finally, we ...
