Comparison of Silicon Lattice-Filter-Based O-Band 1×8 (De)Multiplexers With Flat and Gaussian-Like Passbands

IEEE Photonics Journal, 2022
Based on cascaded Mach-Zehnder interferometer (MZI) lattice filters, we demonstrate and compare silicon O-band 8-channel (de-)multiplexers with flat and Gaussian-like passbands for the 400 GBASE-LR8 norm.

Eigenstructures of MIMO Fading Channel Correlation Matrices and Optimum Linear Precoding Designs for Maximum Ergodic Capacity

EURASIP Journal on Advances in Signal Processing, 2007
The ergodic capacity of MIMO frequency-flat and -selective channels depends greatly on the eigenvalue distribution of spatial correlation matrices. Knowing the eigenstructure of correlation matrices at the transmitter is very important to enhance the ...

Numerical Simulation of Bubble Free Rise after Sudden Contraction Using the Front-Tracking Method

International Journal of Photoenergy, 2017
Based on the front-tracking method (FTM), the movement of a single bubble that rose freely in a transverse ridged tube was simulated to analyze the influence of a contractive channel on the movement of bubbles.

Influence of bottom topography on integral constraints in zonal flows with parameterized potential vorticity fluxes [PDF]

, 2013
An integral constraint for eddy fluxes of potential vorticity (PV), corresponding to global momentum conservation, is applied to two-layer zonal quasi-geostrophic channel flow. This constraint must be satisfied for any type of parameterization of eddy PV

Throughput of Cellular Uplink with Dynamic User Activity and Cooperative Base-Stations

, 2009
The throughput of a linear cellular uplink with a random number of users, different power control schemes, and cooperative base stations is considered in the large system limit where the number of cells is large for non fading Gaussian channels.

Constraints on the pMSSM from searches for squarks and gluinos by ATLAS [PDF]

, 2012
We study the impact of the jets and missing transverse momentum SUSY analyses of the ATLAS experiment on the phenomenological MSSM (pMSSM). We investigate sets of SUSY models with a flat and logarithmic prior in the SUSY mass scale and a mass range up to

Breakthrough in a flat channel membrane microcontactor [PDF]

Chemical Engineering Research and Design, 2015
Abstract In literature three different models describing the breakthrough pressure were identified: the Young–Laplace model, the Kim–Hairrott–Zha model and the Franken et al. model. However, large differences between experimental results and model are often reported and a comparative study is lacking.
