Directive Antenna Clutter Loss in Slant Paths

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper investigates the development of a clutter loss model specifically for slant paths involving directive antennas. Conventionally, clutter loss is characterized by using isotropic antennas to facilitate standard link budget calculations via single antenna gain values.

Carbon Performance in Airlines: A Qualitative Comparative Analysis of Institutional and Firm‐Level Drivers

Sustainable Development, EarlyView.
ABSTRACT Air transport is one of the fastest‐growing sources of greenhouse gas emissions, yet it remains one of the most difficult sectors to decarbonize. The sector's climate impact is amplified by two factors: the steady rise in passenger demand and the absence of commercially viable low‐carbon technologies for long‐haul flights.

Isolation, Insularity and Resilience: A Review of the Geophysical, Socioeconomic, and Environmental Vulnerabilities of Gran Canaria and Lesvos Islands for Policy Interventions to Global Change

Sustainable Development, EarlyView.
ABSTRACT The dynamic nature of small islands being geographically isolated and their perceived connectedness with global networks complicates research attempts to draw general conclusions on whether insularity leads to marginalization or strengthens their resilience for sustainable development.
