Combining Modified Integral Quadrature Method with Simulation Technique to Solve Nonlinear Initial and Boundary Value Problems

open access: yes, 2009
Most ordinary differential equations (ODEs) can be solved using simulation technique (ST), which, however, requires the enforcement of conditions at any time domain, this limitation is the main drawback.

Digital Twin‐Based Optimization of Service Availability in LEO Mega Constellations Considering Handover Delays in Open RAN

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT As non‐terrestrial networks (NTNs) become integral to future 6G systems, ensuring seamless connectivity and service continuity over low Earth orbit (LEO) satellite constellations is essential. This work investigates the impact of open radio access network (RAN) functional splits on handover performance in NTNs, focusing on minimizing service ...

CLEAR Interference Cancellation in a Wideband Dual‐Channel Receiver for Independent Satellite Multi‐Connectivity Links

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT In this paper, the correlation learning estimation and adaptive reduction (CLEAR) of interference, an adaptive, blind and transparent interference compensation method applied in a wideband dual‐channel receiver, is studied for a pair of independent satellite multi‐connectivity links, using the same carrier frequency and signal bandwidth in use

Transforming Paper into Plasmonic Sensors: One‐Step Fabrication of High‐Enhancement SERS Nanosubstrates via Surface Energy Control

open access: yesSmall Methods, EarlyView.
Cellulose paper is transformed into a high‐performance plasmonic sensor through a process called SILVERED, which involves single‐step vapor deposition onto fluorosilanized fibers. Surface‐energy contrast drives uniform silver nanoparticle growth with sub‐10 nm hot‐spot gaps, achieving 2 pM detection of rhodamine B.
