Optimization Study of Valve Closing Schemes for Long‐Distance Gravity Flow Water Supply Systems Based on the NSGA‐II Algorithm

Engineering Reports, Volume 8, Issue 9, September 2026.
Taking the Ruyang Water Supply Project of Qianping Reservoir as the research object, a model was built with Bentley Hammer and valve closure schemes were optimized using the NSGA‑II algorithm. Results show that multistage closure is superior to single‑stage, and the optimized three‑stage scheme provides better water hammer protection, offering ...

Hydroclimatic Changes in the Marsyangdi River Basin, Central Himalaya Under CMIP6 Scenarios: Implications for the Water–Energy–Food–Ecosystem Nexus

Meteorological Applications, Volume 33, Issue 5, September/October 2026.
Under CMIP6 scenarios in the Marsyangdi River Basin, SWAT+ simulations show that warming and shifting precipitation diminish snowfall and cryospheric buffering, deepening pre‐monsoon flow deficits. This seasonal mismatch drives critical Water–Energy–Food–Ecosystem trade‐offs: dry‐season run‐of‐river hydropower generation drop, and increase in winter ...

Integrated LEO Constellation and In‐Cabin Distribution System for Continuous Aircraft 5G Connectivity

International Journal of Satellite Communications and Networking, Volume 44, Issue 5, Page 594-606, September/October 2026.
ABSTRACT The integration of low Earth orbit (LEO) satellite constellations with commercial aircraft communication systems presents critical challenges in maintaining continuous connectivity during dynamic flight conditions. Current geostationary satellite systems suffer from high round‐trip latency ( > 500 ms) and inadequate coverage at high latitudes,

Security–reliability tradeoff analysis of untrusted energy harvesting relay networks

International Journal of Distributed Sensor Networks, 2018
We investigate secure communications in untrusted energy harvesting relay networks, where the amplify-and-forward relay is an energy constrained node powered by the received radio frequency signals, and try to unauthorizedly decode the confidential ...
