Twitter streams are on overload: active users receive hundreds of items per day, and existing interfaces force us to march through a chronologically-ordered morass to find tweets of interest. We present an approach to organizing a user's own feed into coherently clustered trending topics for more directed exploration.

In large federated and shared-nothing databases, resources can exhibit widely fluctuating characteristics. Assumptions made at the time a query is submitted will rarely hold throughout the duration of query processing. As a result, traditional static query optimization and execution techniques are ineffective in these environments.

AbstractRecently, several papers have appeared in the CFD literature, proposing an idealized instability problem as a benchmark for discriminating among numerical algorithms for two‐dimensional Navier–Stokes flows. The problem is a double shear layer simulated at coarse resolution and with a prescribed interface perturbation.

Magnetic hyperthermia is a modern type of treatment, that aims to locally destroy the cancerous tumor. However, one of the restrictions of magnetic hyperthermia therapy is the appearance of eddy currents on healthy human tissues due to the electric field induced by the alternating magnetic field.

Abstract The large-eddy-simulation technique is introduced. The mathematical formulation is presented, and several examples are discussed. Some issues related to the resolution of the wall layer are reviewed. Challenges and possible future developments are addressed.

This chapter describes a night of restlessness and unexpected encounters during the author's camping trip. It mentions how the sounds of waterfowl disturbed both the author and Sully, the dog, whose restless barking added to the difficulty of falling asleep.

As already stressed in the previous chapters, there is a priori no difficulty in envisaging a numerical solution of the unstationary Navier Stokes equations for rotational flows: the various operators are represented by discrete systems relating the values taken by the velocity or vorticity components, pressure, density, temperature, etc...
