Routing and Downlink Resource Allocation for Multicast Traffic in LEO Satellite Constellations
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT In this work, we optimize unicast and multicast traffic delivery over non‐terrestrial networks (NTNs) to users on the ground through direct satellite downlink (DL). We consider a gateway‐free mesh architecture with low Earth orbit (LEO) satellites interconnected via inter‐satellite links (ISLs), where unicast and multicast services compete for

Sustainable Development, EarlyView.ABSTRACT This paper presents a comprehensive policy framework for achieving Sustainable Development Goals 7 and 9 and evaluates the EU's carbon neutrality target for 2050. In this context, the effects of renewable energy consumption, energy R&D budget, energy taxes, and economic growth on the carbon footprint are examined for nine selected EU countries

Advances in Distance-Based Hole Cuts on Overset Grids [PDF]
, 2015 An automatic and efficient method to determine appropriate hole cuts based on distances to the wall and donor stencil maps for overset grids is presented. A new robust procedure is developed to create a closed surface triangulation representation of each

Sustainable Development, EarlyView.ABSTRACT This study investigates how green and non‐green goods, energy transition, digitalization, economic growth, and population affect the material footprint of G‐7 countries from 1990 to 2023. Using an extended STIRPAT framework, we show that green and non‐green goods increase material footprint, demonstrating the resource intensity associated with
