Transport congestion events detection (TCED): towards decorrelating congestion detection from TCP [PDF]

, 2010
TCP (Transmission Control Protocol) uses a loss-based algorithm to estimate whether the network is congested or not. The main difficulty for this algorithm is to distinguish spurious from real network congestion events.

Failure Localization in Power Systems via Tree Partitions [PDF]

, 2018
Cascading failures in power systems propagate non-locally, making the control and mitigation of outages extremely hard. In this work, we use the emerging concept of the tree partition of transmission networks to provide an analytical characterization of ...

Fabrication Method of Directional Microstructure for High Energy Density, High Power Battery Cathodes

Advanced Materials Interfaces, EarlyView.
Aqueous directional ice templating (DIT) is developed for making NMC811 cathodes containing vertically aligned pore arrays through electrode thickness. The effects of calendering are studied for the DIT electrodes to find optimal calendering and simultaneously achieve high gravimetric and volumetric energy densities and rate capability for lithium ion ...

Millisecond‐Switching Dual‐Band/Dual‐Polarization Ka‐Band Wavefront Control Enabled by a Complementary Liquid‐Crystal Metasurface

Advanced Materials Technologies, EarlyView.
An LCD‐compatible complementary liquid‐crystal metasurface delivers dual‐band, dual‐polarized Ka‐band wavefront control with millisecond switching via a 10‐µm LC gap. Interlaced patch/slot pairs enable independent phase tuning at 28 and 38 GHz, while strategic 45° slot rotation suppresses parasitic resonances. Measurements on a 160 × 160‐cell prototype
