Compressible Maps

A Two -Step Modification toward Implementing Compressible Source Terms in Low Compressible Flows

Projections onto the Cone of Optimal Transport Maps and Compressible Fluid Flows

The system of isentropic Euler equations in the potential flow regime can be considered formally as a second order ordinary differential equation on the Wasserstein space of probability measures. This interpretation can be used to derive a variational time discretization. We prove that the approximate solutions generated by this discretization converge to a measure-valued solution of the isentr...

Compressible halftoning

We present a technique for converting continuous gray-scale images to halftone (black and white) images that lend themselves to lossless data compression with compression factor of three or better. Our method involves using novel halftone mask structures which consist of non-repeated threshold values. We have versions of both dispersed-dot and clustered-dot masks, which produce acceptable image...

Modelling Compressible Multiphase Flows

We give in this paper a short review of some recent achievements within the framework of multiphase flow modeling. We focus first on a class of compressible two-phase flow models, detailing closure laws and their main properties. Next we briefly summarize some attempts to model two-phase flows in a porous region, and also a class of compressible three-phase flow models. Some of the main difficu...

Compressible Traffic Features

Despite their diversity, it is well known that traffic anomalies share a common characteristic: they introduce changes in the traffic behavioral aspects defined by certain traffic features, i.e. packet header fields. To apply traffic features for anomaly detection and identification, one promising class of approaches, which were proposed recently [1] [2] [3], have their basis on some analysis o...
