In future high-speed self-routing photonic networks based on all-optical time division multiplexing (OTDM) it is highly desirable to carry out packet switching, clock recovery and demultplexing in the optical domain in order to avoid the bottleneck due to the optoelectronics conversion. In this paper we propose a self-routing OTDM node structure composed of an all-optical router and demultiplex...

We describe certain extremalities for Gallager’s E0 function evaluated under the uniform input distribution for binary input discrete memoryless channels. The results characterize the extremality of the E0(ρ) curves of the binary erasure channel and the binary symmetric channel among all the E0(ρ) curves that can be generated by the class of binary discrete memoryless channels whose E0(ρ) curve...

In the Manning equation the hydraulic radius can be defined as the cross-section dimension of the shape. In pipe flow the bed shear stress is assumed to be uniformly distributed along the wetted perimeter which cannot be true in open channel flow. Hence, three approximation of the true boundary shear-stress distribution are examined and more practical conveyance depth or resistance radius formu...

The purpose of this study is to develop a mathematical model for studying the magnetic field effect on blood flow through an axially non-symmetric but radially symmetric atherosclerotic artery. Herschel-Bulkley equation has been taken to represent the non-Newtonian character of blood. The response of magnetic field, stenosis height, shape parameter on velocity, volumetric flow rate in stenotic ...

If the Standard Model is embedded in a left–right symmetric gauge theory at the TeV scale, the pair production of light W–bosons in ee collisions, ee → WW, will be affected by mixings in the gauge and neutrino sectors, and by the t–channel exchange of a heavy right–handed neutrino. The modification of the cross section by these new effects is studied for high–energy ee colliders.

The electrokinetic flow resistance (electroviscous effect) is predicted for steady state, pressure-driven liquid flow at low Reynolds number in a microfluidic contraction of rectangular cross-section. Calculations of the three dimensional flow are performed in parallel using a finite volume numerical method. The channel walls are assumed to carry a uniform charge density and the liquid is taken...

-Several new results on binary ( d , k ) codes are given. First, a new derivation for the capacity of these codes based upon information theoretic principles is given. Based upon this result the spectrum of a ( d , k ) code is computed. Finally, the problem of computing the capacity of the binary symmetric channel under the condition that the input sequences satisfy the ( d , k ) constraint is ...
