The Uniform Information Density (UID) hypothesis links production strategies with comprehension processes, predicting that speakers will utilize flexibility in encoding in order to increase uniformity in the rate of information transmission, as measured by surprisal (Jaeger, 2010). Evidence in support of UID comes primarily from studies focusing on word-level effects, e.g. demonstrating that su...

We consider multidimensional cosmologies in even-dimensional space-times (D = 2n) containg perfect uid and a multidimensional generalization of the Maxwell eld FA 1 An preserving its conformal invariance. Among models with an isotropic physical 3-space some integrable cases are found: vacuum models (which are integrable in the general case) and some perfect uid models with barotropic equations ...

A model is developed for the ow of a slightly compressible uid through a saturated inelastic porous medium. The initial-boundary-value problem is a system that consists of the di usion equation for the uid coupled to the momentum equation for the porous solid together with a constitutive law which includes a possibly hysteretic relation of elasto-visco-plastic type. The variational form of this...

We present here the experimental determination of the dispersion relation of surface waves of a ferro uid submitted to a steady vertical magnetic eld. The results are compared to a linear theory where all the magnetic characteristics of the uid have been taken into account. The knowledge of the dispersion equation is then used to analyse the capillary-wave resistance, that is the drag force ass...

This paper introduces the framework of synchronous constrained uid systems (SCFS) to model queueing networks driven synchronously by general uid virtual departure processes, and explores structural properties of queueing networks that t this model. The synchronous timing mechanism used in this paper allows us to model sources and servers with time-varying capacity as in communication systems wi...
