Non-unique flows in macroscopic first-order intersection models

Currently, most intersection models embedded in macroscopic Dynamic Network Loading (DNL) models are not well suited for urban and regional applications. This is so because so-called internal intersection supply constraints, bounding flows due to crossing ...

On inconsistent entities. A reply to Colyvan

Francesco Piazza

In a recent article M. Colyvan has argued that Quinean forms of scientific realism are faced with an unexpected upshot. Realism concerning a given class of entities, along with this route to realism, can be vindicated by running an indispensability argumen ...

Analyse non-linéaire des coques géodésiques multicouches à joints semi-rigides

Julius Natterer

In the 90ies the IBOIS-EPFL developed a new kind of shell structure. The ribs were made with simple boards waved together to form a spatial rib shell. However, the engineer currently does not have any effective method to calculate these kinds of spatial st ...

Solution of the tunneling-percolation problem in the nanocomposite regime

Peter Ryser, Claudio Grimaldi, Thomas Maeder, Gianluca Ambrosetti

We noted that the tunneling-percolation framework is quite well understood at the extreme cases of percolation-like and hopping-like behaviors but that the intermediate regime has not been previously discussed, in spite of its relevance to the intensively ...

Techniques for generating centimetric drops in microgravity and application to cavitation studies

Mohamed Farhat, Nicolas Dorsaz, Danail Obreschkow, Philipp Kobel, Aurèle De Bosset

This paper describes the techniques and physical parameters used to produce stable centimetric water drops in microgravity, and to study single cavitation bubbles inside such drops (Parabolic Flight Campaigns, European Space Agency ESA). While the main sci ...

Mathematicals Models in Science and Engineering

Alfio Quarteroni

Mathematical models, along with scientific theory and practical experiments, are a crucial part of modern engineering and science. The author takes a look at the role mathematical models play in topics ranging from vascular simulation to weather forecastin ...

Particle transport in tokamak plasmas, theory and experiment

Henri Weisen, Mikhail Maslov, Emiliano Fable

The physical processes producing electron particle transport in the core of tokamak plasmas are described. Starting from the gyrokinetic equation, a simple analytical derivation is used as guidance to illustrate the main mechanisms driving turbulent partic ...

The Coherence of Theories-Dependencies and Weights

Jingshi Li

One way to evaluate and compare rival but potentially incompatible theories that account for the same set of observations is coherence. In this paper we take the quantitative notion of theory coherence as proposed by [Kwok, et.al. 98] and broaden its found ...

Keeping in touch with one's self: multisensory mechanisms of self-consciousness

Olaf Blanke, Jane Aspell, Bigna Lenggenhager

BACKGROUND: The spatial unity between self and body can be disrupted by employing conflicting visual-somatosensory bodily input, thereby bringing neurological observations on bodily self-consciousness under scientific scrutiny. Here we designed a novel par ...

Anomalous Magnetic Excitations of Cooperative Tetrahedral Spin Clusters

Henrik Moodysson Rønnow, Helmuth Berger, Joël Mesot, Johan Juul Chang, Krunoslav Prsa

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 ...
