Minimization of Transmission Line Losses Through System Topology Reconfiguration
EnergiesThis research proposes a methodology for minimizing losses in transmission lines (TLs), considering the reconfiguration of the architecture of the electrical power system (EPS). The implementation of this methodology redirects the power flow with optimal

Tunable room temperature magnetic skyrmions in centrosymmetric kagome magnet Mn4Ga2Sn
Communications Physics, 2022 Skyrmions are vortex-like magnetic textures typically observed in non-centrosymmetric systems, i.e. those with no centre of inversion. Here, using Lorentz transmission electron microscopy supported with micromagnetic simulations the authors report the ...

Energy-Optimal Scheduling in Low Duty Cycle Sensor Networks [PDF]
, 2011 Energy consumption of a wireless sensor node mainly depends on the amount of time the node spends in each of the high power active (e.g., transmit, receive) and low power sleep modes.

Advanced Functional Materials, EarlyView.In this strategy, a conductive nano‐probe is employed to induce nanoscale phase transitions and map the nanoscale conductivity and trap density of GST films. By utilizing the contrasting properties of phase‐change states, nano‐resonators are fabricated that exhibit plasmonic conduction and dramatically different transport characteristics.

An Agile-Beam NOMA Scheme in Millimeter Wave Networks
IEEE Access, 2019 We propose an agile-beam non-orthogonal multiple access (NOMA) scheme for millimeter wave (mmWave) communication networks. The agile-beam NOMA scheme can flexibly switch between the single/multi-beam NOMA transmission depending on the angular phase ...

Advanced Functional Materials, EarlyView.Ferroelectricity in thin HfO2‐based films offers great possibilities for next‐generation neuromorphic memory devices. There, the response to subcoercive voltage signals is driven by the movement of mobile interfaces and their interaction with crystal defects – a yet rather unexplored aspect, which we shed light on and gain new insights into the complex
