Using modern differential geometric methods, we study the relative equilibria for Dirichlet's model of a self-gravitating fluid mass having at least two equal axes. We show that the only relative equilibria of this type correspond to Riemann ellipsoids for ...
This work constitutes the first extended analysis of the spatial structure of Type-I ELM filament footprints on the JET outer limiters and upper dump plates. The data is obtained using a wide angle infrared diagnostic (with time resolution of 125 Hz) and c ...
An important microstructural aspect of the early hydration of Portland cement (K) is the formation of a shell of hydration products around cement grains. There is, at present, limited information on the mechanism of formation of the shell and of the chemis ...
This paper presents a method for measurement-system design through criteria related to model based structural identification. Using a multi-model approach and results from previous research carried out at EPFL, an improved algorithm is proposed. The algori ...
We study the problem of distributed estimation, where a set of nodes are required to collectively estimate some parameter of interest from their measurements. Distributed implementations avoid the use of a fusion center and distribute the processing and co ...
An inelastic neutron scattering study of Cu2Te2O5X2 (X=Cl, Br) shows strong dispersive modes with large energy gaps persisting far above T-N, notably in Cu2Te2O5Br2. The anomalous features: a coexisting unusually weak Goldstone-like mode observed in Cu2Te2 ...
The conditional indirect utility of many random utility maximization (RUM) discrete choice models is specified as a sum of an index V depending on observables and an independent random term. In general, the universe of RUM consistent models is much larger, ...
In this paper, we present an application of RFIDs for supply-chain management. In our application, we consider two types of readers. On one part, we have readers that will mark tags at given points. After that, these tags can be checked by another type of ...
An important application of unique object references is safe and efficient message passing in concurrent object-oriented programming. However, to prevent the ill effects of aliasing, practical systems often severely restrict the shape of messages passed by ...
Strengthening of dislocations by multiple obstacle types occurs in many engineering alloys. Theories have rationalized two different scaling laws for the total strength, tau(alpha)(t) = tau(alpha)(1) + tau(alpha)(2) with alpha = 1 or 2, where tau(1) and ta ...
