In this paper, a generalization of the traditional point-to-point to communication setup, which is named as “reliable communications with asymmetric codebooks”, is proposed. Under the assumption of independent identically distributed (i.i.d) encoder codewords, it is proven that the operational capacity of the system is equal to the information capacity of the system, which is given by maxp(x) I...

In this work, we examine fluid mixing in a full three-stream mixing channel with longitudinal vortex generators (LVGs) built on the channel bottom by numerical simulation and experiment. The effects of the asymmetrical arrangement and the attack angle of the LVGs on fluid mixing are investigated. The results show that the micromixer with LVGs at a small asymmetry index (defined by the ratio of ...

symmetry has been for a century and continues to be a subject of interest in lens design. The study of these systems is relevant for understanding the effects of fabrication and assembly errors in lenses nominally designed as axially symmetric,' for designing reflective systems without a central obstruction,2 or for designing exotic systems that provide a practical solution to a difficult probl...

The effect of the asymmetric water entry over a submerged part of a ship on the hydrodynamic impact is investigated numerically. A wedge body is considered to study and the problem is assumed to be two-dimensional. The Results of symmetric and asymmetric impacts are compared together. The effect is found significant in the numerical simulation. The maximum hydrodynamic pressure at a heel angle ...
